Energy Conservation Program: Energy Conservation Standards for 
Refrigerators, Refrigerator-Freezers, and Freezers

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of 
Energy.

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The Energy Policy and Conservation Act, as amended (``EPCA''), 
prescribes energy conservation standards for various consumer products 
and certain commercial and industrial equipment, including 
refrigerators, refrigerator-freezers, and freezers. In this direct 
final rule, the U.S. Department of Energy (``DOE'') is adopting amended 
energy conservation standards for refrigerators, refrigerator-freezers, 
and freezers. DOE has determined that the amended energy conservation 
standards for these products would result in significant conservation 
of energy, and are technologically feasible and economically justified.

DATES: The effective date of this rule is May 16, 2024. The 
incorporation by reference of certain material listed in the rule was 
approved by the Director as of May 21, 2014, and November 12, 2021. If 
adverse comments are received by May 6, 2024, and DOE determines that 
such comments may provide a reasonable basis for withdrawal of the 
direct final rule under 42 U.S.C. 6295(o), a timely withdrawal of this 
rule will be published in the Federal Register. If no such adverse 
comments are received, compliance with the amended standards 
established for refrigerators, refrigerator-freezers, and freezers in 
this direct final rule is required on and after January 31, 2029, for 
the product classes listed in Table I.1 and January 31, 2030, for the 
product classes listed in Table I.2.

I. Synopsis of the Direct Final Rule

    The Energy Policy and Conservation Act, Public Law 94-163, as 
amended (``EPCA''),\1\ authorizes DOE to regulate the energy efficiency 
of a number of consumer products and certain industrial equipment. (42 
U.S.C. 6291-6317) Title III, Part B of EPCA \2\ established the Energy 
Conservation Program for Consumer Products Other Than Automobiles. (42 
U.S.C. 6291-6309) These products include refrigerators, refrigerator-
freezers, and freezers, the subject of this direct final rule. (42 
U.S.C. 6292(a)(7))
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020, Public Law 116-260 (Dec. 
27, 2020), which reflect the last statutory amendments that impact 
Parts A and A-1 of EPCA.
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
---------------------------------------------------------------------------

    Pursuant to EPCA, any new or amended energy conservation standard 
must, among other things, be designed to achieve the maximum 
improvement in energy efficiency that DOE determines is technologically 
feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) 
Furthermore, the new or amended standard must result in significant 
conservation of energy. (42 U.S.C. 6295(o)(3)(B))
    In light of the above and under the authority provided by 42 U.S.C. 
6295(p)(4), DOE is issuing this direct final rule amending energy 
conservation standards for refrigerators, refrigerator-freezers, and 
freezers.
    The adopted standard levels in this direct final rule were proposed 
in a letter submitted to DOE jointly by groups representing 
manufacturers, energy and environmental advocates, consumer groups, and 
a utility. This letter, titled ``Energy Efficiency Agreement of 2023'' 
(hereafter, the ``Joint Agreement''),\3\ recommends specific energy 
conservation standards for refrigerators, refrigerator-freezers, and 
freezers that, in the commenters' view, would satisfy the EPCA 
requirements in 42 U.S.C. 6295(o). DOE subsequently received letters of 
support from states including California, Massachusetts, and New York 
\4\ and utilities including San Diego Gas and Electric (``SDG&E'') and 
Southern California Edison (``SCE'') \5\ advocating for the adoption of 
the recommended standards and a follow-up letter from the parties to 
the Joint Agreement that more specifically described the recommended 
standards for refrigerators, refrigerator-freezers, and freezers, and 
their rationale for entering into a negotiation to develop them.\6\
---------------------------------------------------------------------------

    \3\ This document is available in the docket at: 
www.regulations.gov/document/EERE-2017-BT-STD-0003-0103.
    \4\ This document is available in the docket at:

    \6\ This document is available in the docket at: 
www.regulations.gov/document/EERE-2017-BT-STD-0003-0105.
---------------------------------------------------------------------------

    In accordance with the direct final rule provisions at 42 U.S.C. 
6295(p)(4), DOE has determined that the recommendations contained in 
the Joint Agreement are compliant with 42 U.S.C. 6295(o). As required 
by 42 U.S.C. 6295(p)(4)(A)(i), DOE is also simultaneously publishing a 
notice of proposed rulemaking (``NOPR'') that contains identical 
standards to those adopted in this direct final rule. Consistent with 
the statute, DOE is providing a 110-day public comment period on the 
direct final rule. (42 U.S.C. 6295(p)(4)(B)) If DOE determines that any 
comments received provide a reasonable basis for withdrawal of the 
direct final rule under 42 U.S.C. 6295(o) or any other applicable law, 
DOE will publish the reasons for withdrawal and continue the rulemaking 
under the NOPR. (42 U.S.C. 6295(p)(4)(C)) See section II.A of this 
document for more details on DOE's statutory authority.
    The amended standards that DOE is adopting in this direct final 
rule are the efficiency levels recommended in the Joint Agreement 
(shown in Tables I.1 and I.2) expressed in terms of kilowatt hours per 
year (``kWh/yr'') as measured according to DOE's current refrigerator, 
refrigerator-freezer, and freezer test procedures codified at title 10 
of the Code of Federal Regulations (``CFR''), part 430, subpart B, 
appendices A (``appendix A'') and B (``appendix B'').
    The amended standards recommended in the Joint Agreement are 
represented as trial standard level (``TSL'') 4 in this document 
(hereinafter the ``Recommended TSL'') and are described in section V.A 
of this document. These standards apply to all products listed in Table 
I.1 and manufactured in, or imported into the United States starting on 
January 31, 2029, and all products listed in Table I.2 and manufactured 
in, or imported into, the United States starting on January 31, 2030.

A. Benefits and Costs to Consumers

    Table I.3 summarizes DOE's evaluation of the economic impacts of 
the adopted standards on consumers of refrigerators, refrigerator-
freezers, and freezers, as measured by the average life-cycle cost 
(``LCC'') savings and the simple payback period (``PBP'').\7\ The 
average LCC savings are positive for all product classes for which a 
standard is proposed, and the PBP is less than the average lifetime of 
refrigerators, refrigerator-freezers, and freezers, which varies by 
product class (see section IV.F.7 of this document).
---------------------------------------------------------------------------

    \7\ The average LCC savings refer to consumers that are affected 
by a standard and are measured relative to the efficiency 
distribution in the no-new-standards case, which depicts the market 
in the compliance year in the absence of new or amended standards 
(see section IV.F.9 of this document). The simple PBP, which is 
designed to compare specific efficiency levels, is measured relative 
to the baseline product (see section IV.C of this document).

    DOE's analysis of the impacts of the adopted standards on consumers 
is described in section IV.F of this document.

B. Impact on Manufacturers <SUP>8</SUP>
---------------------------------------------------------------------------

    \8\ All monetary values in this document are expressed in 2022 
dollars.
---------------------------------------------------------------------------

    The industry net present value (``INPV'') is the sum of the 
discounted cash flows to the industry from the base year (2023) through 
the end of the analysis period, which is 30 years from the analyzed 
compliance date.\9\ Using a real discount rate of 9.1 percent, DOE 
estimates that the INPV for manufacturers of refrigerators, 
refrigerator-freezers, and freezers in the case without amended 
standards is $4.91 billion.\10\ Under the adopted standards, which 
align with the Recommended TSL for refrigerators, refrigerator-
freezers, and freezers, DOE estimates the change in INPV to range from 
-10.3 percent to -7.8 percent, which is approximately -$504.4 million 
to -$383.5 million. In order to bring products into compliance with 
amended standards, it is estimated that industry will incur total 
conversion costs of $830.3 million.
---------------------------------------------------------------------------

    \9\ DOE's analysis period extends 30-years from the compliance 
year. The analysis period ranges from 2023-2056 for the no-new-
standards case and all TSLs, except for TSL 4 (the Recommended TSL). 
The analysis period for TSL 4 ranges from 2023-2058 for the product 
classes listed in Table I.1 and 2023-2059 for the product classes 
listed in Table I.2.
    \10\ The no-new-standards case INPV of $4.91 billion reflects 
the sum of discounted free cash flows from 2023-2056 (from direct 
final rule publication to 30 years from the 2027 compliance date) 
plus a discounted terminal value.
---------------------------------------------------------------------------

    DOE's analysis of the impacts of the adopted standards on 
manufacturers is described in sections IV.J and V.B.2 of this document.

C. National Benefits and Costs

    DOE's analyses indicate that the adopted energy conservation 
standards for refrigerators, refrigerator-freezers, and freezers would 
save a significant amount of energy. Relative to the case without 
amended standards, the lifetime energy savings for refrigerators, 
refrigerator-freezers, and freezers purchased in the 30-year period 
that begins in the anticipated year of compliance with amended 
standards (2029-2058 for the product classes listed in Table I.1 and 
2030-2059 for the product classes listed in Table I.2), amount to 5.6 
quadrillion British thermal units (``Btu''), or quads.\11\ This 
represents a savings of 11 percent relative to the energy use of these 
products in the case without amended standards (referred to as the 
``no-new-standards case'').
---------------------------------------------------------------------------

    \11\ The quantity refers to full-fuel-cycle (``FFC'') energy 
savings. FFC energy savings includes the energy consumed in 
extracting, processing, and transporting primary fuels (i.e., coal, 
natural gas, petroleum fuels), and, thus, presents a more complete 
picture of the impacts of energy efficiency standards. For more 
information on the FFC metric, see section of this document.
---------------------------------------------------------------------------

    The cumulative net present value (``NPV'') of total consumer 
benefits of the standards for refrigerators, refrigerator-freezers, and 
freezers ranges from $9.0 billion (at a 7-percent discount rate) to 
$27.0 billion (at a 3-percent discount rate). This NPV expresses the 
estimated total value of future operating cost savings minus the 
estimated increased product costs for refrigerators, refrigerator-
freezers, and freezers purchased in 2029-2058 for the product classes 
listed in Table I.1 and 2030-2059 for the product classes listed in 
Table I.2.
    In addition, the adopted standards for refrigerators, refrigerator-
freezers, and freezers are projected to yield significant environmental 
benefits. DOE estimates that the standards will result in cumulative 
emission reductions (over the same period as for energy savings) of 
100.8 million metric tons (``Mt'') \12\ of carbon dioxide 
(``CO<INF>2</INF>''), 31.6 thousand tons of sulfur dioxide 
(``SO<INF>2</INF>''), 186.1 thousand tons of nitrogen oxides 
(``NO<INF>X</INF>''), 846.5 thousand tons of methane 
(``CH<INF>4</INF>''), 1.0 thousand tons of nitrous oxide 
(``N<INF>2</INF>O''), and 0.2 tons of mercury (``Hg'').\13\
---------------------------------------------------------------------------

    \12\ A metric ton is equivalent to 1.1 short tons. Results for 
emissions other than CO<INF>2</INF> are presented in short tons.
    \13\ DOE calculated emissions reductions relative to the no-new-
standards-case, which reflects key assumptions in the Annual Energy 
Outlook 2023 (``AEO2023''). AEO2023 represents current Federal and 
State legislation and final implementation of regulations as of the 
time of its preparation. See section IV.K of this document for 
further discussion of AEO2023 assumptions that affect air pollutant 
emissions.
---------------------------------------------------------------------------

    DOE estimates the value of climate benefits from a reduction in 
greenhouse gases (``GHG'') using four different estimates of the social 
cost of CO<INF>2</INF> (``SC-CO<INF>2</INF>''), the social cost of 
methane (``SC-CH<INF>4</INF>''), and the social cost of nitrous oxide 
(``SC-N<INF>2</INF>O''). Together these represent the social cost of 
GHG (``SC-GHG''). DOE used interim SC-GHG values developed by an 
Interagency Working Group on the Social Cost of Greenhouse Gases 
(``IWG'').\14\ The derivation of these values is discussed in section 
IV.L of this document. For presentational purposes, the climate 
benefits associated with the average SC-GHG at a 3-percent discount 
rate are estimated to be $5.0 billion. DOE does not have a single 
central SC-GHG point estimate and it emphasizes the importance and 
value of considering the benefits calculated using all four sets of SC-
GHG estimates.
---------------------------------------------------------------------------

    \14\ To monetize the benefits of reducing GHG emissions this 
analysis uses the interim estimates presented in the Technical 
Support Document: Social Cost of Carbon, Methane, and Nitrous Oxide 
Interim Estimates Under Executive Order 13990 published in February 
2021 by the IWG (``February 2021 SC-GHG TSD''). www.whitehouse.gov/wp-content/uploads/2021/02/TechnicalSupportDocument_SocialCostofCarbonMethaneNitrousOxide.pdf.
---------------------------------------------------------------------------

    DOE estimated the monetary health benefits of SO<INF>2</INF> and 
NO<INF>X</INF> emissions reductions, using benefit-per-ton estimates 
from the scientific literature, as discussed in section IV.L of this 
document. DOE estimated the present value of the health benefits would 
be $3.4 billion using a 7-percent discount rate, and $9.8 billion using 
a 3-percent

[[Page 3031]]

discount rate.\15\ DOE is currently only monetizing (for SO<INF>2</INF> 
and NO<INF>X</INF>) PM<INF>2.5</INF> precursor health benefits and (for 
NO<INF>X</INF>) ozone precursor health benefits, but will continue to 
assess the ability to monetize other effects such as health benefits 
from reductions in direct PM<INF>2.5</INF> emissions.
---------------------------------------------------------------------------

    \15\ DOE estimates the economic value of these emissions 
reductions resulting from the considered TSLs for the purpose of 
complying with the requirements of Executive Order 12866.
---------------------------------------------------------------------------

    Table I.4 summarizes the monetized benefits and costs expected to 
result from the amended standards for refrigerators, refrigerator-
freezers, and freezers. There are other important unquantified effects, 
including certain unquantified climate benefits, unquantified public 
health benefits from the reduction of toxic air pollutants and other 
emissions, unquantified energy security benefits, and distributional 
effects, among others.

Note: This table presents present value (in 2022$) of the costs and
  benefits associated with refrigerators, refrigerator-freezers, and
  freezers shipped in 2029-2058 for the product classes listed in Table
  I.1 and shipped in 2030-2059 for the product classes listed in Table
  I.2. These results include benefits which accrue after 2058/9 from the
  products shipped in 2029/30-2058/9.
* Climate benefits are calculated using four different estimates of the
  social cost of carbon (SC-CO2), methane (SC-CH4), and nitrous oxide
  (SC-N2O) (model average at 2.5-percent, 3-percent, and 5-percent
  discount rates; 95th percentile at 3-percent discount rate) (see
  section IV.L of this document). Together these represent the global SC-
  GHG. For presentational purposes of this table, the climate benefits
  associated with the average SC-GHG at a 3-percent discount rate are
  shown; however DOE emphasizes the importance and value of considering
  the benefits calculated using all four sets of SC-GHG estimates. To
  monetize the benefits of reducing GHG emissions, this analysis uses
  the interim estimates presented in the Technical Support Document:
  Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates
  Under Executive Order 13990 published in February 2021 by the IWG.
** Health benefits are calculated using benefit-per-ton values for NOX
  and SO2. DOE is currently only monetizing (for SO2 and NOX) PM2.5
  precursor health benefits and (for NOX) ozone precursor health
  benefits, but will continue to assess the ability to monetize other
  effects such as health benefits from reductions in direct PM2.5
  emissions. See section IV.L of this document for more details.
[dagger] Total and net benefits include those consumer, climate, and
  health benefits that can be quantified and monetized. For presentation
  purposes, total and net benefits for both the 3-percent and 7-percent
  cases are presented using the average SC-GHG with 3-percent discount
  rate, but DOE does not have a single central SC-GHG point estimate.
  DOE emphasizes the importance and value of considering the benefits
  calculated using all four sets of SC-GHG estimates.
[Dagger][Dagger] Operating Cost Savings are calculated based on the life-
  cycle costs analysis and national impact analysis as discussed in
  detail below. See sections IV.F and IV.H of this document. DOE's
  national impact analysis (``NIA'') includes all impacts (both costs
  and benefits) along the distribution chain beginning with the
  increased costs to the manufacturer to manufacture the product and
  ending with the increase in price experienced by the consumer. DOE
  also separately conducts a detailed analysis on the impacts on
  manufacturers (the MIA). See section IV.J of this document. In the
  detailed MIA, DOE models manufacturers' pricing decisions based on
  assumptions regarding investments, conversion costs, cashflow, and
  margins. The MIA produces a range of impacts, which is the rule's
  expected impact on the INPV. The change in INPV is the present value
  of all changes in industry cash flow, including changes in production
  costs, capital expenditures, and manufacturer profit margins. Change
  in INPV is calculated using the industry weighted average cost of
  capital value of 9.1 percent that is estimated in the manufacturer
  impact analysis (see chapter 12 of the direct final rule technical
  support document (``TSD'') for a complete description of the industry
  weighted average cost of capital). For refrigerators, refrigerator-
  freezers, and freezers, those values are -$504 million to -$383
  million. DOE accounts for that range of likely impacts in analyzing
  whether a TSL is economically justified. See section V.C of this
  document. DOE is presenting the range of impacts to the INPV under two
  markup scenarios: the Preservation of Gross Margin scenario, which is
  the manufacturer markup scenario used in the calculation of Consumer
  Operating Cost Savings in this table, and the Preservation of
  Operating Profit scenario, where DOE assumed manufacturers would not
  be able to increase per-unit operating profit in proportion to
  increases in manufacturer production costs. DOE includes the range of
  estimated INPV in the above table, drawing on the MIA explained
  further in section IV.J of this document, to provide additional
  context for assessing the estimated impacts of this direct final rule
  to society, including potential changes in production and consumption,
  which is consistent with OMB's Circular A-4 and E.O. 12866. If DOE
  were to include the INPV into the net benefit calculation for this
  direct final rule, the net benefits would range from $41.3 billion to
  $41.4 billion at 3-percent discount rate and would range from $17.0
  billion to $17.1 billion at 7-percent discount rate. Parentheses ( )
  indicate negative values.


[[Page 3032]]

    The benefits and costs of the proposed standards can also be 
expressed in terms of annualized values. The monetary values for the 
total annualized net benefits are (1) the reduced consumer operating 
costs, minus (2) the increase in product purchase prices and 
installation costs, plus (3) the value of climate and health benefits 
of emission reductions, all annualized.\16\
---------------------------------------------------------------------------

    \16\ To convert the time-series of costs and benefits into 
annualized values, DOE calculated a present value in 2022, the year 
used for discounting the NPV of total consumer costs and savings. 
For the benefits, DOE calculated a present value associated with 
each year's shipments in the year in which the shipments occur 
(e.g., 2020 or 2030), and then discounted the present value from 
each year to 2022. Using the present value, DOE then calculated the 
fixed annual payment over a 30-year period, starting in the 
compliance year, that yields the same present value.
---------------------------------------------------------------------------

    The national operating cost savings are domestic private U.S. 
consumer monetary savings that occur as a result of purchasing the 
covered products and are measured for the lifetime of refrigerators, 
refrigerator-freezers, and freezers shipped in 2029-2058 for the 
product classes listed in Table I.1 and shipped in 2030-2059 for the 
product classes listed in Table I.2. The benefits associated with 
reduced emissions achieved as a result of the adopted standards are 
also calculated based on the lifetime of refrigerators, refrigerator-
freezers, and freezers shipped in 2029-2058 for the product classes 
listed in Table I.1 and shipped in 2030-2059 for the product classes 
listed in Table I.2. Total benefits for both the 3-percent and 7-
percent cases are presented using the average GHG social costs with 3-
percent discount rate. Estimates of SC-GHG values are presented for all 
four discount rates in section IV.L of this document.
    Table I.5 presents the total estimated monetized benefits and costs 
associated with the proposed standard, expressed in terms of annualized 
values. The results under the primary estimate are as follows.
    Using a 7-percent discount rate for consumer benefits and costs and 
health benefits from reduced NO<INF>X</INF> and SO<INF>2</INF> 
emissions, and the 3-percent discount rate case for climate benefits 
from reduced GHG emissions, the estimated cost of the standards adopted 
in this rule is $590.5 million per year in increased equipment costs, 
while the estimated annual monetized benefits are $1.7 billion in 
reduced equipment operating costs, $303.8 million in climate benefits, 
and $410.6 million in health benefits. In this case, the net benefit 
would amount to $1.8 billion per year.
    Using a 3-percent discount rate for all benefits and costs, the 
estimated cost of the standards is $567.5 million per year in increased 
equipment costs, while the estimated annual monetized benefits are $2.2 
billion in reduced operating costs, $303.8 million in climate benefits, 
and $592.9 million in health benefits. In this case, the net benefit 
would amount to $2.5 billion per year.

Note: This table presents present value (in 2022$) of the costs and benefits associated with refrigerators,
  refrigerator-freezers, and freezers shipped in 2029-2058 for the product classes listed in Table I.1 and
  shipped in 2030-2059 for the product classes listed in Table I.2. These results include benefits which accrue
  after 2056 from the products shipped in 2029-2058 for the product classes listed in Table I.1 and shipped in
  2030-2059 for the product classes listed in Table I.2. The Primary, Low Net Benefits, and High Net Benefits
  Estimates utilize projections of energy prices from the AEO2023 Reference case, Low Economic Growth case, and
  High Economic Growth case, respectively. In addition, incremental equipment costs reflect a medium decline
  rate in the Primary Estimate, a low decline rate in the Low Net Benefits Estimate, and a high decline rate in
  the High Net Benefits Estimate. The methods used to derive projected price trends are explained in section
  IV.H.3 of this document. Note that the Benefits and Costs may not sum to the Net Benefits due to rounding.
* Climate benefits are calculated using four different estimates of the global SC-GHG (see section IV.L of this
  document). For presentational purposes of this table, the climate benefits associated with the average SC-GHG
  at a 3-percent discount rate are shown; however, DOE emphasizes the importance and value of considering the
  benefits calculated using all four sets of SC-GHG estimates. To monetize the benefits of reducing GHG
  emissions, this analysis uses the interim estimates presented in the Technical Support Document: Social Cost
  of Carbon, Methane.

[[Page 3033]]

 
** Health benefits are calculated using benefit-per-ton values for NOX and SO2. DOE is currently only monetizing
  (for SO2 and NOX) PM2.5 precursor health benefits and (for NOX) ozone precursor health benefits, but will
  continue to assess the ability to monetize other effects such as health benefits from reductions in direct
  PM2.5 emissions. See section IV.L of this document for more details.
[dagger] Total benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with 3-
  percent discount rate, but DOE does not have a single central SC-GHG point estimate.
[Dagger][Dagger] Operating Cost Savings are calculated based on the life-cycle costs analysis and national
  impact analysis as discussed in detail below. See sections IV.F and IV.H of this document. DOE's NIA includes
  all impacts (both costs and benefits) along the distribution chain beginning with the increased costs to the
  manufacturer to manufacture the product and ending with the increase in price experienced by the consumer. DOE
  also separately conducts a detailed analysis on the impacts on manufacturers (the MIA). See section IV.J of
  this document. In the detailed MIA, DOE models manufacturers' pricing decisions based on assumptions regarding
  investments, conversion costs, cashflow, and margins. The MIA produces a range of impacts, which is the rule's
  expected impact on the INPV. The change in INPV is the present value of all changes in industry cash flow,
  including changes in production costs, capital expenditures, and manufacturer profit margins. The annualized
  change in INPV is calculated using the industry weighted average cost of capital value of 9.1 percent that is
  estimated in the manufacturer impact analysis (see chapter 12 of the direct final rule TSD for a complete
  description of the industry weighted average cost of capital). For refrigerators, refrigerator-freezers, and
  freezers, those values are -$48.7 million to -$37.0 million. DOE accounts for that range of likely impacts in
  analyzing whether a TSL is economically justified. See section V.C of this document. DOE is presenting the
  range of impacts to the INPV under two manufacturer markup scenarios: the Preservation of Gross Margin
  scenario, which is the manufacturer markup scenario used in the calculation of Consumer Operating Cost Savings
  in this table, and the Preservation of Operating Profit Markup scenario, where DOE assumed manufacturers would
  not be able to increase per-unit operating profit in proportion to increases in manufacturer production costs.
  DOE includes the range of estimated annualized change in INPV in the above table, drawing on the MIA explained
  further in section IV.J of this document, to provide additional context for assessing the estimated impacts of
  this direct final rule to society, including potential changes in production and consumption, which is
  consistent with OMB's Circular A-4 and E.O. 12866. If DOE were to include the INPV into the annualized net
  benefit calculation for this direct final rule, the annualized net benefits would range from $2,480.9 million
  to $2,492.6 million at 3-percent discount rate and would range from $1,742.2 million to $1,753.9 million at 7-
  percent discount rate. Parentheses ( ) indicate negative values.

    DOE's analysis of the national impacts of the adopted standards is 
described in sections IV.H, IV.K, and IV.L of this document.

D. Conclusion

    DOE has determined that the Joint Agreement was submitted jointly 
by interested persons that are fairly representative of relevant points 
of view, in accordance with 42 U.S.C. 6295(p)(4)(A). After considering 
the recommended standards and weighing the benefits and burdens, DOE 
has determined that the recommended standards are in accordance with 42 
U.S.C. 6295(o), which contains the criteria for prescribing new or 
amended standards. Specifically, the Secretary has determined that the 
adoption of the recommended standards would result in the significant 
conservation of energy and is the maximum improvement in energy 
efficiency that is technologically feasible and economically justified. 
In determining whether the recommended standards are economically 
justified, the Secretary has determined that the benefits of the 
recommended standards exceed the burdens. The Secretary has further 
concluded that the recommended standards, when considering the benefits 
of energy savings, positive NPV of consumer benefits, emission 
reductions, the estimated monetary value of the emissions reductions, 
and positive average LCC savings, would yield benefits that outweigh 
the negative impacts on some consumers and on manufacturers, including 
the conversion costs that could result in a reduction in INPV for 
manufacturers.
    Using a 7-percent discount rate for consumer benefits and costs and 
NO<INF>X</INF> and SO<INF>2</INF> reduction benefits, and a 3-percent 
discount rate case for GHG social costs, the estimated cost of the 
standards for refrigerators, refrigerator-freezers, and freezers is 
$590.5 million per year in increased product costs, while the estimated 
annual monetized benefits are $1.7 billion in reduced product operating 
costs, $303.8 million in climate benefits, and $410.6 million in health 
benefits. The net monetized benefit amounts to $1.8 billion per year.
    The significance of energy savings offered by a new or amended 
energy conservation standard cannot be determined without knowledge of 
the specific circumstances surrounding a given rulemaking.\17\ For 
example, some covered products and equipment have most of their energy 
consumption occur during periods of peak energy demand. The impacts of 
these products on the energy infrastructure can be more pronounced than 
products with relatively constant demand. Accordingly, DOE evaluates 
the significance of energy savings on a case-by-case basis.

---------------------------------------------------------------------------

    As previously mentioned, the standards are projected to result in 
estimated national energy savings of 5.6 quads (full-fuel cycle 
(``FFC'')), the equivalent of the primary annual energy use of 37 
million homes. In addition, they are projected to reduce CO<INF>2</INF> 
emissions by 100.8 Mt. Based on these findings, DOE has determined the 
energy savings from the standard levels adopted in this direct final 
rule are ``significant'' within the meaning of 42 U.S.C. 6295(o)(3)(B). 
A more detailed discussion of the basis for these conclusions is 
contained in the remainder of this document and the accompanying

    Under the authority provided by 42 U.S.C. 6295(p)(4), DOE is 
issuing this direct final rule amending the energy conservation 
standards for refrigerators, refrigerator-freezers, and freezers. 
Consistent with this authority, DOE is also simultaneously publishing 
elsewhere in this Federal Register a NOPR proposing standards that are 
identical to those contained in this direct final rule. See 42 U.S.C. 
6295(p)(4)(A)(i).

II. Introduction

    The following section briefly discusses the statutory authority 
underlying this direct final rule, as well as some of the relevant 
historical background related to the establishment of standards for 
refrigerators, refrigerator-freezers, and freezers.

A. Authority

    EPCA authorizes DOE to regulate the energy efficiency of a number 
of consumer products and certain industrial equipment. Title III, Part 
B of EPCA established the Energy Conservation Program for Consumer 
Products Other Than Automobiles. These products include refrigerators, 
refrigerator-freezers, and freezers, the subject of this document. (42 
U.S.C. 6292(a)(1)) EPCA prescribed energy conservation standards for 
these products (42 U.S.C. 6295(b)(1)), and directed DOE to conduct 
future rulemakings to determine whether to amend these standards. (42 
U.S.C. 6295(b)(3)) EPCA further provides that, not later than 6 years 
after the issuance of any final rule establishing or

[[Page 3034]]

amending a standard, DOE must publish either a notice of determination 
that standards for the product do not need to be amended, or a NOPR 
including new proposed energy conservation standards (proceeding to a 
final rule, as appropriate). (42 U.S.C. 6295(m)(1))
    The energy conservation program under EPCA consists essentially of 
four parts: (1) testing, (2) labeling, (3) the establishment of Federal 
energy conservation standards, and (4) certification and enforcement 
procedures. Relevant provisions of EPCA specifically include 
definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293), 
labeling provisions (42 U.S.C. 6294), energy conservation standards (42 
U.S.C. 6295), and the authority to require information and reports from 
manufacturers (42 U.S.C. 6296).
    Federal energy efficiency requirements for covered products 
established under EPCA generally supersede State laws and regulations 
concerning energy conservation testing, labeling, and standards. (42 
U.S.C. 6297(a)-(c)) DOE may, however, grant waivers of Federal 
preemption in limited instances for particular State laws or 
regulations, in accordance with the procedures and other provisions set 
forth under EPCA. (See 42 U.S.C. 6297(d))
    Subject to certain criteria and conditions, DOE is required to 
develop test procedures to measure the energy efficiency, energy use, 
or estimated annual operating cost of each covered product. (42 U.S.C. 
6295(o)(3)(A) and 42 U.S.C. 6295(Ir)) Manufacturers of covered products 
must use the prescribed DOE test procedure as the basis for certifying 
to DOE that their products comply with the applicable energy 
conservation standards adopted under EPCA and when making 
representations to the public regarding the energy use or efficiency of 
those products. (42 U.S.C. 6293(c) and 6295(s)) Similarly, DOE must use 
these test procedures to determine whether the products comply with 
standards adopted pursuant to EPCA. (42 U.S.C. 6295(s)) The DOE test 
procedures for refrigerators, refrigerator-freezers, and freezers 
appear at 10 CFR part 430, subpart B, appendix A, Uniform Test Method 
for Measuring the Energy Consumption of Refrigerators, Refrigerator-
Freezers, and Miscellaneous Refrigeration Products (``appendix A''), 
and appendix B, Uniform Test Method for Measuring the Energy 
Consumption of Freezers (``appendix B'').
    DOE must follow specific statutory criteria for prescribing new or 
amended standards for covered products, including refrigerators, 
refrigerator-freezers, and freezers. Any new or amended standard for a 
covered product must be designed to achieve the maximum improvement in 
energy efficiency that the Secretary of Energy determines is 
technologically feasible and economically justified. (42 U.S.C. 
6295(o)(2)(A) and 42 U.S.C. 6295(o)(3)(B)) Furthermore, DOE may not 
adopt any standard that would not result in the significant 
conservation of energy. (42 U.S.C. 6295(o)(3)(B))
    Moreover, DOE may not prescribe a standard (1) for certain 
products, including refrigerators, refrigerator-freezers, and freezers, 
if no test procedure has been established for the product, or (2) if 
DOE determines by rule that the standard is not technologically 
feasible or economically justified. (42 U.S.C. 6295(o)(3)(A)-(B)) In 
deciding whether a proposed standard is economically justified, DOE 
must determine whether the benefits of the standard exceed its burdens. 
(42 U.S.C. 6295(o)(2)(B)(i)) DOE must make this determination after 
receiving comments on the proposed standard, and by considering, to the 
greatest extent practicable, the following seven statutory factors:
    (1) The economic impact of the standard on manufacturers and 
consumers of the products subject to the standard;
    (2) The savings in operating costs throughout the estimated average 
life of the covered products in the type (or class) compared to any 
increase in the price, initial charges, or maintenance expenses for the 
covered products that are likely to result from the standard;
    (3) The total projected amount of energy (or as applicable, water) 
savings likely to result directly from the standard;
    (4) Any lessening of the utility or the performance of the covered 
products likely to result from the standard;
    (5) The impact of any lessening of competition, as determined in 
writing by the Attorney General, that is likely to result from the 
standard;
    (6) The need for national energy and water conservation; and
    (7) Other factors the Secretary of Energy (``Secretary'') considers 
relevant.
    (42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII))
    Further, EPCA, as codified, establishes a rebuttable presumption 
that a standard is economically justified if the Secretary finds that 
the additional cost to the consumer of purchasing a product complying 
with an energy conservation standard level will be less than three 
times the value of the energy savings during the first year that the 
consumer will receive as a result of the standard, as calculated under 
the applicable test procedure. (42 U.S.C. 6295(o)(2)(B)(iii))
    EPCA, as codified, also contains what is known as an ``anti-
backsliding'' provision, which prevents the Secretary from prescribing 
any amended standard that either increases the maximum allowable energy 
use or decreases the minimum required energy efficiency of a covered 
product. (42 U.S.C. 6295(o)(1)) Also, the Secretary may not prescribe 
an amended or new standard if interested persons have established by a 
preponderance of the evidence that the standard is likely to result in 
the unavailability in the United States in any covered product type (or 
class) of performance characteristics (including reliability), 
features, sizes, capacities, and volumes that are substantially the 
same as those generally available in the United States. (42 U.S.C. 
6295(o)(4))
    EPCA specifies requirements when promulgating an energy 
conservation standard for a covered product that has two or more 
subcategories. A rule prescribing an energy conservation standard for a 
type (or class) of product must specify a different standard level for 
a type or class of products that has the same function or intended use 
if DOE determines that products within such group (A) consume a 
different kind of energy from that consumed by other covered products 
within such type (or class); or (B) have a capacity or other 
performance-related feature which other products within such type (or 
class) do not have and such feature justifies a higher or lower 
standard. (42 U.S.C. 6295(q)(1)) In determining whether a performance-
related feature justifies a different standard for a group of products, 
DOE consider such factors as the utility to the consumer of such a 
feature and other factors DOE deems appropriate. Id. Any rule 
prescribing such a standard must include an explanation of the basis on 
which such higher or lower level was established. (42 U.S.C. 
6295(q)(2))
    Additionally, pursuant to the amendments contained in the Energy 
Independence and Security Act of 2007 (``EISA 2007''), Public Law 110-
140, final rules for new or amended energy conservation standards 
promulgated after July 1, 2010, are required to address standby mode 
and off mode energy use. (42 U.S.C. 6295(gg)(3)) Specifically, when DOE 
adopts a standard for a covered product after that date, it must, if 
justified by the criteria for adoption of standards under EPCA (42 
U.S.C. 6295(o)), incorporate standby mode and off mode energy use into 
a single standard, or, if that is not feasible,

[[Page 3035]]

adopt a separate standard for such energy use for that product. (42 
U.S.C. 6295(gg)(3)(A)-(B)) DOE's current test procedures and standards 
for refrigerators, refrigerator-freezers, and freezers address standby 
mode and off mode energy use, as do the amended standards adopted in 
this direct final rule.
    Finally, EISA 2007 amended EPCA, in relevant part, to grant DOE 
authority to issue a final rule (i.e., a ``direct final rule'') 
establishing an energy conservation standard upon receipt of a 
statement submitted jointly by interested persons that are fairly 
representative of relevant points of view (including representatives of 
manufacturers of covered products, States, and efficiency advocates), 
as determined by the Secretary, that contains recommendations with 
respect to an energy or water conservation standard. (42 U.S.C. 
6295(p)(4)) Pursuant to 42 U.S.C. 6295(p)(4), the Secretary must also 
determine whether a jointly-submitted recommendation for an energy or 
water conservation standard satisfies 42 U.S.C. 6295(o) or 42 U.S.C. 
6313(a)(6)(B), as applicable.
    The direct final rule must be published simultaneously with a NOPR 
that proposes an energy or water conservation standard that is 
identical to the standard established in the direct final rule, and DOE 
must provide a public comment period of at least 110 days on this 
proposal. (42 U.S.C. 6295(p)(4)(A)-(B)) While DOE typically provides a 
comment period of 60 days on proposed standards, for a NOPR 
accompanying a direct final rule, DOE provides a comment period of the 
same length as the comment period on the direct final rule--i.e., 110 
days. Based on the comments received during this period, the direct 
final rule will either become effective, or DOE will withdraw it not 
later than 120 days after its issuance if: (1) one or more adverse 
comments is received, and (2) DOE determines that those comments, when 
viewed in light of the rulemaking record related to the direct final 
rule, may provide a reasonable basis for withdrawal of the direct final 
rule under 42 U.S.C. 6295(o), 42 U.S.C. 6313(a)(6)(B), or any other 
applicable law. (42 U.S.C. 6295(p)(4)(C)) Receipt of an alternative 
joint recommendation may also trigger a DOE withdrawal of the direct 
final rule in the same manner. (Id.)
    DOE has previously explained its interpretation of its direct final 
rule authority. In a final rule amending the Department's ``Procedures, 
Interpretations and Policies for Consideration of New or Revised Energy 
Conservation Standards for Consumer Products'' at 10 CFR part 430, 
subpart C, appendix A, DOE noted that it may issue standards 
recommended by interested persons that are fairly representative of 
relative points of view as a direct final rule when the recommended 
standards are in accordance with 42 U.S.C. 6295(o) or 6313(a)(6)(B), as 
applicable. 86 FR 70892, 70912 (Dec. 13, 2021). But the direct final 
rule provision in EPCA does not impose additional requirements 
applicable to other standards rulemakings, which is consistent with the 
unique circumstances of rules issued as consensus agreements under 
DOE's direct final rule authority. Id. DOE's discretion remains bounded 
by its statutory mandate to adopt a standard that results in the 
maximum improvement in energy efficiency that is technologically 
feasible and economically justified--a requirement found in 42 U.S.C. 
6295(o). Id. As such, DOE's review and analysis of the Joint Agreement 
is limited to whether the recommended standards satisfy the criteria in 
42 U.S.C. 6295(o).

B. Background

1. Current Standards
    In a final rule published on September 15, 2011 (``September 2011 
Final Rule''), DOE prescribed the current energy conservation standards 
for refrigerators, refrigerator-freezers, and freezers manufactured on 
and after September 15, 2014. 76 FR 57516. These standards are set 
forth in DOE's regulations at 10 CFR 430.32(a).
2. Current Test Procedure
    On December 23, 2019, DOE published a test procedure NOPR 
(``December 2019 TP NOPR'') proposing to amend residential 
refrigerator, refrigerator-freezer, and freezer test procedure. 84 FR 
70842. On October 12, 2021, DOE published a test procedure final rule 
(``October 2021 TP Final Rule'') establishing test procedures for 
refrigerators, refrigerator-freezers, and freezers, at 10 CFR part 430, 
subpart B, appendices A (``appendix A'') and B (``appendix B''). 86 FR 
56790. The test procedure adopted the latest version of the relevant 
industry standard published by the Association of Home Appliance 
Manufacturers (``AHAM''), updated in 2019, AHAM Standard HRF-1, 
``Energy and Internal Volume of Refrigerating Appliances'' (``HRF-1-
2019''). 10 CFR 430.3(i)(4). The standard levels proposed in the NOPR 
are based on the annual energy use (``AEU'') metrics as measured 
according to appendices A and B.
History of Standards Rulemaking for Consumer Refrigerators, 
Refrigerator-Freezers, and Freezers
    The National Appliance Energy Conservation Act of 1987 (``NAECA''), 
Public Law 100-12, amended EPCA to establish prescriptive standards for 
refrigeration products, with requirements that DOE conduct two cycles 
of rulemakings to determine whether to amend these standards (42 U.S.C. 
6295 (b)(1), (2), (3)(A)(i), and (3)(B)-(C)). DOE completed the first 
of these rulemaking cycles in 1989 and 1990 by adopting amended 
performance standards for all refrigeration products manufactured on or 
after January 1, 1993. 54 FR 47916 (November 17, 1989); 55 FR 42845 
(October 24, 1990). DOE completed a second rulemaking cycle to amend 
the standards for refrigeration products by issuing a final rule in 
1997, which adopted the current standards for these products. 62 FR 
23102 (April 28, 1997).
    In 2005, DOE granted a petition, submitted by a coalition of state 
governments, utility companies, consumer and low-income advocacy 
groups, and environmental and energy efficiency organizations, 
requesting a rulemaking to amend the standards for residential 
refrigerator-freezers. DOE then conducted limited analyses to examine 
the technological and economic feasibility of amended standards at the 
ENERGY STAR levels that were in effect for 2005 for the two most 
popular product classes of refrigerator-freezers. These analyses not 
only identified potential energy savings, benefits, and burdens from 
such standards, but also assessed other issues related to them.
    DOE initiated a rulemaking and also published a notice announcing 
the availability of the framework document and a public meeting to 
discuss the document in September 2008. It also requested public 
comment on the published document. 73 FR 54089 (September 18, 2008). 
The framework document described the procedural and analytical 
approaches that DOE anticipated using to evaluate energy conservation 
standards for refrigeration products and identified various issues to 
resolve during the rulemaking. DOE published a final rule on September 
15, 2011, to satisfy the statutory requirement that DOE publish a final 
rule to determine whether to amend the standards for refrigeration 
products manufactured in 2014. (42 U.S.C. 6295(b)(4)) The limited 2005 
analyses served as background for the more extensive analysis conducted 
for final

rule published on September 15, 2011. 76 FR 57516.
4. The Joint Agreement
    On September 25, 2023, DOE received a joint statement (i.e., the 
Joint Agreement) recommending standards for refrigerators, 
refrigerator-freezers, and freezers that was submitted by groups 
representing manufacturers, energy and environmental advocates, 
consumer groups, and a utility.\19\ In addition to the recommended 
standards for refrigerators, refrigerator-freezers, and freezers, the 
Joint Agreement also included separate recommendations for several 
other covered products.\20\ And, while acknowledging that DOE may 
implement these recommendations in separate rulemakings, the Joint 
Agreement also stated that the recommendations were recommended as a 
complete package and each recommendation is contingent upon the other 
parts being implemented. DOE understands this to mean that the Joint 
Agreement is contingent upon DOE initiating rulemaking processes to 
adopt all of the recommended standards in the agreement. That is 
distinguished from an agreement where issuance of an amended energy 
conservation standard for a covered product is contingent on issuance 
of amended energy conservation standards for the other covered 
products. If the Joint Agreement were so construed, it would conflict 
with the anti-backsliding provision in 42 U.S.C. 6295(o)(1), because it 
would imply the possibility that, if DOE were unable to issue an 
amended standard for a certain product, it would have to withdraw a 
previously issued standard for one of the other products. The anti-
backsliding provision, however, prevents DOE from withdrawing or 
amending an energy conservation standard to be less stringent. As a 
result, DOE will be proceeding with individual rulemakings that will 
evaluate each of the recommended standards separately under the 
applicable statutory criteria. The Joint Agreement recommends amended 
standard levels for refrigerators, refrigerator-freezers, and freezers 
as presented in Table II.3. (Joint Agreement, No. 103 at p. 4) Details 
of the Joint Agreement recommendations for other products are provided 
in the Joint Agreement posted in the docket.\21\

American Council for an Energy-Efficient Economy, Alliance for Water 
Efficiency, Appliance Standards Awareness Project, Consumer 
Federation of America, Consumer Reports, Earthjustice, National 
Consumer Law Center, Natural Resources Defense Council, Northwest

    DOE notes that it was conducting a rulemaking to consider amending 
the standards for refrigerators, refrigerator-freezers, and freezers 
when the Joint Agreement was submitted. As part of that process, on 
February 27, 2023, DOE published a NOPR and announced a public webinar 
(``February 2023 NOPR'') seeking comment on its proposed amended 
standard to inform its decision consistent with its obligations under 
EPCA and the Administrative Procedure Act (``APA''). 88 FR 12452. DOE 
held a public webinar on April 11, 2023, to discuss and receive 
comments on the NOPR and NOPR TSD. The NOPR TSD is available at: 
www.regulations.gov/document/EERE-2017-BT-STD-0003-0045.
    Although DOE is adopting the Joint Agreement as a direct final rule 
and no longer proceeding with its own rulemaking, DOE did consider 
relevant comments, data, and information obtained during that 
rulemaking process in determining whether the recommended standards 
from the Joint Agreement are in accordance with 42 U.S.C. 6295(o). Any 
discussion of comments, data, or information in this direct final rule 
that were obtained during DOE's own prior rulemaking will include a 
parenthetical reference that provides the location of the item in the 
public record.\22\
---------------------------------------------------------------------------

    \22\ The parenthetical reference provides a reference for 
information located in the docket of DOE's rulemaking to develop 
energy conservation standards for refrigerators, refrigerator-
freezers, and freezers (Docket No. EERE-2017-BT-STD-0003, which is 
maintained at www.regulations.gov). The references are arranged as 
follows: (commenter name, comment docket ID number, page of that 
document).
---------------------------------------------------------------------------

III. General Discussion

    DOE is issuing this direct final rule after determining that the 
recommended standards submitted in the Joint Agreement meet the 
requirements in 42 U.S.C. 6295(p)(4). More specifically, DOE has 
determined that the recommended standards were submitted by interested 
persons that are fairly representative of relevant points of view and 
the recommended standards satisfy the criteria in 42 U.S.C. 6295(o).

A. Scope of Coverage

    This direct final rule covers those consumer products that meet the 
definition of ``refrigerator, refrigerator-freezer, and freezer'' as 
codified at 10 CFR 430.2.
    When evaluating and establishing energy conservation standards, DOE 
divides covered products into product classes by the type of energy 
used, or by capacity, or based upon performance-related features that 
justify a higher or lower standard. (42 U.S.C. 6295(q)) In making a 
determination whether a performance-related feature justifies a

[[Page 3038]]

different standard, DOE must consider such factors as the utility of 
the feature to the consumer and other factors DOE determines are 
appropriate. Id.
    The Joint Agreement proposed special door and multi-door energy 
allowances for product classes if manufacturers offer models with those 
features. Energy allowances applied to energy use equations correspond 
to performance-related features that would then justify new product 
classes for those configurations with special door and multi-door 
designs. The proposed approach also embeds within the energy use 
equations the difference between classes that are otherwise identical 
except for presence of an icemaker, using a logical variable I (equal 
to 1 for a product with an icemaker and equal to 0 for a product 
without an icemaker) multiplied by the constant icemaker energy use 
adder.
    The structure simplification and amendments in the Joint Agreement 
are consistent with those proposed by DOE in the February 2023 NOPR. 
Based on the comments received in response to the February 2023 NOPR 
and DOE's evaluation of the Joint Agreement, the direct final rule 
adopts these changes. See section IV.A.1 of this document for further 
detail and discussion regarding the product classes analyzed in this 
direct final rule.

B. Fairly Representative of Relevant Points of View

    Under the direct final rule provision in EPCA, recommended energy 
conservation standards must be submitted by interested persons that are 
fairly representative of relevant points of view (including 
representatives of manufacturers of covered products, States, and 
efficiency advocates) as determined by DOE. (42 U.S.C. 6295(p)(4)(A)) 
With respect to this requirement, DOE notes that the Joint Agreement 
included a trade association, AHAM, which represents 20 manufacturers 
of refrigerators, refrigerator-freezers, and freezers. The Joint 
Agreement also included environmental and energy-efficiency advocacy 
organizations, consumer advocacy organizations, and a gas and electric 
utility company. Additionally, DOE received a letter in support of the 
Joint Agreement from the States of New York, California, and 
Massachusetts (see comment No. 104). DOE also received a letter in 
support of the Joint Agreement from the gas and electric utility, 
SDG&E, and the electric utility, SCE (see comment No. 107). As a 
result, DOE has determined that the Joint Agreement was submitted by 
interested persons who are fairly representative of relevant points of 
view.

C. Technological Feasibility

1. General
    In each energy conservation standards rulemaking, DOE conducts a 
screening analysis based on information gathered on all current 
technology options and prototype designs that could improve the 
efficiency of the products or equipment that are the subject of the 
rulemaking. As the first step in such an analysis, DOE develops a list 
of technology options for consideration in consultation with 
manufacturers, design engineers, and other interested parties. DOE then 
determines which of those means for improving efficiency are 
technologically feasible. DOE considers technologies incorporated in 
commercially available products or in working prototypes to be 
technologically feasible. Sections 6(b)(3)(i) and 7(b)(1) of appendix A 
to 10 CFR part 430, subpart C (``Process Rule'').
    After DOE has determined that particular technology options are 
technologically feasible, it further evaluates each technology option 
in light of the following additional screening criteria: (1) 
practicability to manufacture, install, and service; (2) adverse 
impacts on product utility or availability; (3) adverse impacts on 
health or safety and (4) unique-pathway proprietary technologies. 
Section 7(b)(2)-(5) of the Process Rule. Section IV.B of this document 
discusses the results of the screening analysis for refrigerators, 
refrigerator-freezers, and freezers, particularly the designs DOE 
considered, those it screened out, and those that are the basis for the 
standards considered in this rulemaking. For further details on the 
screening analysis for this rulemaking, see chapter 4 of the direct 
final rule TSD.
2. Maximum Technologically Feasible Levels
    When DOE proposes to adopt an amended standard for a type or class 
of covered product, it must determine the maximum improvement in energy 
efficiency or maximum reduction in energy use that is technologically 
feasible for such product. (42 U.S.C. 6295(o)(2)(A)) Accordingly, in 
the engineering analysis, DOE determined the maximum technologically 
feasible (``max-tech'') improvements in energy efficiency for 
refrigerators, refrigerator-freezers, and freezers, using the design 
parameters for the most efficient products available on the market or 
in working prototypes. The max-tech levels that DOE determined for this 
rulemaking are described in section IV.C of this document and in 
chapter 5 of the direct final rule TSD.

D. Energy Savings

1. Determination of Savings
    For each trial standard level (``TSL''), DOE projected energy 
savings from application of the TSL to refrigerators, refrigerator-
freezers, and freezers purchased in the 30-year period that begins in 
the year of compliance with the amended standards (2027-2056 for all 
TSLs other than TSL 4; for TSL 4, 2029-2058 for the product classes 
listed in Table I.1 and 2030-2059 for the product classes listed in 
Table I.2).\23\ The savings are measured over the entire lifetime of 
products purchased in the 30-year analysis period. DOE quantified the 
energy savings attributable to each TSL as the difference in energy 
consumption between each standards case and the no-new-standards case. 
The no-new-standards case represents a projection of energy consumption 
that reflects how the market for a product would likely evolve in the 
absence of amended energy conservation standards.
---------------------------------------------------------------------------

    \23\ DOE also presents a sensitivity analysis that considers 
impacts for products shipped in a 9-year period.
---------------------------------------------------------------------------

    DOE used its national impact analysis (``NIA'') spreadsheet models 
to estimate national energy savings (``NES'') from potential amended 
standards for refrigerators, refrigerator-freezers, and freezers. The 
NIA spreadsheet model (described in section IV.H of this document) 
calculates energy savings in terms of site energy, which is the energy 
directly consumed by products at the locations where they are used. For 
electricity, DOE reports national energy savings in terms of primary 
energy savings, which is the savings in the energy that is used to 
generate and transmit the site electricity. For natural gas, the 
primary energy savings are considered to be equal to the site energy 
savings. DOE also calculates NES in terms of full-fuel cycle (``FFC'') 
energy savings. The FFC metric includes the energy consumed in 
extracting, processing, and transporting primary fuels (i.e., coal, 
natural gas, petroleum fuels), and thus presents a more complete 
picture of the impacts of energy conservation standards.\24\ DOE's 
approach is based on the calculation of an FFC multiplier for each of 
the energy types used by covered products or

[[Page 3039]]

equipment. For more information on FFC energy savings, see section 
IV.H.2 of this document.
---------------------------------------------------------------------------

    \24\ The FFC metric is discussed in DOE's statement of policy 
and notice of policy amendment. 76 FR 51282 (Aug. 18, 2011), as 
amended at 77 FR 49701 (Aug. 17, 2012).
---------------------------------------------------------------------------

2. Significance of Savings
    To adopt any new or amended standards for a covered product, DOE 
must determine that such action would result in significant energy 
savings. (42 U.S.C. 6295(o)(3)(B))
    The significance of energy savings offered by a new or amended 
energy conservation standard cannot be determined without knowledge of 
the specific circumstances surrounding a given rulemaking.\25\ For 
example, some covered products and equipment have most of their energy 
consumption occur during periods of peak energy demand. The impacts of 
these products on the energy infrastructure can be more pronounced than 
products with relatively constant demand. However, residential 
refrigerators, freezers, and refrigerator-freezers have loads that are 
more consistent throughout the year. Accordingly, DOE evaluates the 
significance of energy savings on a case-by-case basis, taking into 
account the significance of cumulative FFC national energy savings, the 
cumulative FFC emissions reductions, and the need to confront the 
global climate crisis, among other factors.
---------------------------------------------------------------------------

in New or Revised Energy Conservation Standards and Test Procedures 
for Consumer Products and Commercial/Industrial Equipment, 86 FR 
70892, 70901 (Dec. 13, 2021).
---------------------------------------------------------------------------

    As stated, the standard levels adopted in this direct final rule 
are projected to result in national energy savings of 5.6 quads (FFC), 
the equivalent of the primary annual energy use of 37 million homes. 
Based on the amount of FFC savings, the corresponding reduction in 
emissions, and need to confront the global climate crisis, DOE has 
determined the energy savings from the standard levels adopted in this 
direct final rule are ``significant'' within the meaning of 42 U.S.C. 
6295(o)(3)(B).

E. Economic Justification

1. Specific Criteria
    As noted previously, EPCA provides seven factors to be evaluated in 
determining whether a potential energy conservation standard is 
economically justified. (42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII)) The 
following sections discuss how DOE has addressed each of those seven 
factors in this rulemaking.
a. Economic Impact on Manufacturers and Consumers
    In determining the impacts of potential amended standards on 
manufacturers, DOE conducts an MIA, as discussed in section IV.J of 
this document. DOE first uses an annual cash flow approach to determine 
the quantitative impacts. This step includes both a short-term 
assessment--based on the cost and capital requirements during the 
period between when a regulation is issued and when entities must 
comply with the regulation--and a long-term assessment over a 30-year 
period. The industry-wide impacts analyzed include (1) INPV, which 
values the industry on the basis of expected future cash flows; (2) 
cash flows by year; (3) changes in revenue and income; and (4) other 
measures of impact, as appropriate. Second, DOE analyzes and reports 
the impacts on different types of manufacturers, including impacts on 
small manufacturers. Third, DOE considers the impact of standards on 
domestic manufacturer employment and manufacturing capacity, as well as 
the potential for standards to result in plant closures and loss of 
capital investment. Finally, DOE takes into account cumulative impacts 
of various DOE regulations and other regulatory requirements on 
manufacturers.
    For individual consumers, measures of economic impact include the 
changes in LCC and payback period (``PBP'') associated with new or 
amended standards. These measures are discussed further in the 
following section. For consumers in the aggregate, DOE also calculates 
the national net present value of the consumer costs and benefits 
expected to result from particular standards. DOE also evaluates the 
impacts of potential standards on identifiable subgroups of consumers 
that may be affected disproportionately by a standard.
b. Savings in Operating Costs Compared To Increase in Price (LCC and 
PBP)
    EPCA requires DOE to consider the savings in operating costs 
throughout the estimated average life of the covered product in the 
type (or class) compared to any increase in the price of, or in the 
initial charges for, or maintenance expenses of, the covered product 
that are likely to result from a standard. (42 U.S.C. 
6295(o)(2)(B)(i)(II)) DOE conducts this comparison in its LCC and PBP 
analysis.
    The LCC is the sum of the purchase price of a product (including 
its installation) and the operating cost (including energy, 
maintenance, and repair expenditures) discounted over the lifetime of 
the product. The LCC analysis requires a variety of inputs, such as 
product prices, product energy consumption, energy prices, maintenance 
and repair costs, product lifetime, and discount rates appropriate for 
consumers. To account for uncertainty and variability in specific 
inputs, such as product lifetime and discount rate, DOE uses a 
distribution of values, with probabilities attached to each value.
    The PBP is the estimated amount of time (in years) it takes 
consumers to recover the increased purchase cost (including 
installation) of a more efficient product through lower operating 
costs. DOE calculates the PBP by dividing the change in purchase cost 
due to a more stringent standard by the change in annual operating cost 
for the year that standards are assumed to take effect.
    For its LCC and PBP analysis, DOE assumes that consumers will 
purchase the covered products in the first year of compliance with new 
or amended standards. The LCC savings for the considered efficiency 
levels are calculated relative to the case that reflects projected 
market trends in the absence of new or amended standards. DOE's LCC and 
PBP analysis is discussed in further detail in section IV.F of this 
document.
c. Energy Savings
    Although significant conservation of energy is a separate statutory 
requirement for adopting an energy conservation standard, EPCA requires 
DOE, in determining the economic justification of a standard, to 
consider the total projected energy savings that are expected to result 
directly from the standard. (42 U.S.C. 6295(o)(2)(B)(i)(III)) As 
discussed in section IV.H of this document, DOE uses the NIA 
spreadsheet models to project national energy savings.
d. Lessening of Utility or Performance of Products
    In evaluating design options and the impact of potential standard 
levels, DOE evaluates potential standards that would not lessen the 
utility or performance of the considered products. (42 U.S.C. 
6295(o)(2)(B)(i)(IV)) Based on data available to DOE, the standards 
adopted in this document would not reduce the utility or performance of 
the products under consideration in this rulemaking.
e. Impact of Any Lessening of Competition
    EPCA directs DOE to consider the impact of any lessening of 
competition, as determined in writing by the Attorney General, that is 
likely to result from a standard. (42 U.S.C. 6295(o)(2)(B)(i)(V)) It 
also directs the Attorney General to determine the impact, if any, of 
any lessening of

[[Page 3040]]

competition likely to result from a standard and to transmit such 
determination to the Secretary within 60 days of the publication of a 
proposed rule, together with an analysis of the nature and extent of 
the impact. (42 U.S.C. 6295(o)(2)(B)(ii)) DOE will transmit a copy of 
this direct final rule to the Attorney General with a request that the 
Department of Justice (``DOJ'') provide its determination on this 
issue. DOE will consider DOJ's comments on the rule in determining 
whether to withdraw the direct final rule. DOE will also publish and 
respond to the DOJ's comments in the Federal Register in a separate 
document.
f. Need for National Energy Conservation
    DOE also considers the need for national energy and water 
conservation in determining whether a new or amended standard is 
economically justified. (42 U.S.C. 6295(o)(2)(B)(i)(VI)) The energy 
savings from the adopted standards are likely to provide improvements 
to the security and reliability of the Nation's energy system. 
Reductions in the demand for electricity also may result in reduced 
costs for maintaining the reliability of the Nation's electricity 
system. DOE conducts a utility impact analysis to estimate how 
standards may affect the Nation's needed power generation capacity, as 
discussed in section IV.M of this document.
    DOE maintains that environmental and public health benefits 
associated with the more efficient use of energy are important to take 
into account when considering the need for national energy 
conservation. The adopted standards are likely to result in 
environmental benefits in the form of reduced emissions of air 
pollutants and greenhouse gases (``GHGs'') associated with energy 
production and use. DOE conducts an emissions analysis to estimate how 
potential standards may affect these emissions, as discussed in section 
IV.K of this document; the estimated emissions impacts are reported in 
section V.B.6 of this document. DOE also estimates the economic value 
of emissions reductions resulting from the considered TSLs, as 
discussed in section IV.L of this document.
g. Other Factors
    In determining whether an energy conservation standard is 
economically justified, DOE may consider any other factors that the 
Secretary deems to be relevant. (42 U.S.C. 6295(o)(2)(B)(i)(VII)) To 
the extent DOE identifies any relevant information regarding economic 
justification that does not fit into the other categories described 
previously, DOE could consider such information under ``other 
factors.''
2. Rebuttable Presumption
    As set forth in 42 U.S.C. 6295(o)(2)(B)(iii), EPCA creates a 
rebuttable presumption that an energy conservation standard is 
economically justified if the additional cost to the consumer of a 
product that meets the standard is less than three times the value of 
the first year's energy savings resulting from the standard, as 
calculated under the applicable DOE test procedure. DOE's LCC and PBP 
analyses generate values used to calculate the effect potential amended 
energy conservation standards would have on the payback period for 
consumers. These analyses include, but are not limited to, the 3-year 
payback period contemplated under the rebuttable-presumption test. In 
addition, DOE routinely conducts an economic analysis that considers 
the full range of impacts to consumers, manufacturers, the Nation, and 
the environment, as required under 42 U.S.C. 6295(o)(2)(B)(i). The 
results of this analysis serve as the basis for DOE's evaluation of the 
economic justification for a potential standard level (thereby 
supporting or rebutting the results of any preliminary determination of 
economic justification). The rebuttable-presumption payback calculation 
is discussed in section IV.F of this document.

IV. Methodology and Discussion of Related Comments

    This section addresses the analyses DOE has performed for this 
rulemaking with regard to refrigerators, refrigerator-freezers, and 
freezers. Separate subsections address each component of DOE's 
analyses, including relevant comments DOE received during its separate 
rulemaking to amend the energy conservation standards for 
refrigerators, refrigerator-freezers, and freezers prior to receiving 
the Joint Agreement.
    DOE used several analytical tools to estimate the impact of the 
standards considered in this document. The first tool is a spreadsheet 
that calculates the LCC savings and PBP of potential amended or new 
energy conservation standards. The national impacts analysis uses a 
second spreadsheet set that provides shipments projections and 
calculates national energy savings and net present value of total 
consumer costs and savings expected to result from potential energy 
conservation standards. DOE uses the third spreadsheet tool, the 
Government Regulatory Impact Model (``GRIM''), to assess manufacturer 
impacts of potential standards. These three spreadsheet tools are 
available on the DOE website for this rulemaking: www.regulations.gov/docket/EERE-2017-BT-STD-0003. Additionally, DOE used output from the 
latest version of the Energy Information Administration's (``EIA's'') 
Annual Energy Outlook (``AEO'') for the emissions and utility impact 
analyses.

A. Market and Technology Assessment

    DOE develops information in the market and technology assessment 
that provides an overall picture of the market for the products 
concerned, including the purpose of the products, the industry 
structure, manufacturers, market characteristics, and technologies used 
in the products. This activity includes both quantitative and 
qualitative assessments, based primarily on publicly available 
information. The subjects addressed in the market and technology 
assessment for this rulemaking include (1) a determination of the scope 
of the rulemaking and product classes, (2) manufacturers and industry 
structure, (3) existing efficiency programs, (4) shipments information, 
(5) market and industry trends, and (6) technologies or design options 
that could improve the energy efficiency of refrigerators, 
refrigerator-freezers, and freezers. The key findings of DOE's market 
assessment are summarized in the following sections. See chapter 3 of 
the direct final rule TSD for further discussion of the market and 
technology assessment.
1. Product Classes
    The Joint Agreement specifies 32 product classes for refrigerators, 
refrigerator-freezers, and freezers. (Joint Agreement, No. 103 at p. 
15-16) In particular, the Joint Agreement recommends a consolidated 
product class representation which incorporates icemaker energy adders 
and door allowances into the energy use equations for product classes 
in which they are applicable. In addition, the Join Agreement proposes 
a new product class--upright built-in freezers with automatic defrost 
and through-the-door ice service (``9A-BI''). (Id.) In this direct 
final rule, DOE is adopting the product classes from the Joint 
Agreement, as listed in Table IV.1.

------------------------------------------------------------------------

    DOE further notes that product classes established through EPCA's 
direct final rule authority are not subject to the criteria specified 
at 42 U.S.C. 6295(q)(1) for establishing product classes. Nevertheless, 
in accordance with 42 U.S.C. 6295(o)(4)--which is applicable to direct 
final rules--DOE has concluded that the standards adopted in this 
direct final rule will not result in the unavailability in any covered 
product type (or class) of performance characteristics, features, 
sizes, capacities, and volumes that are substantially the same as those 
generally available in the United States currently.\26\ DOE's findings 
in this regard are discussed in detail in section V.B.4 of this 
document.
---------------------------------------------------------------------------

    \26\ EPCA specifies that DOE may not prescribe an amended or new 
standard if the Secretary finds (and publishes such finding) that 
interested persons have established by a preponderance of the 
evidence that the standard is likely to result in the unavailability 
in the United States in any covered product type (or class) of 
performance characteristics (including reliability), features, 
sizes, capacities, and volumes that are substantially the same as 
those generally available in the United States at the time of the 
Secretary's finding. (42 U.S.C. 6295(o)(4))
---------------------------------------------------------------------------

a. Product Classes With Automatic Icemakers
    The Joint Agreement includes a proposed simplification of maximum 
allowable energy and would express the maximum allowable energy use for 
both icemaking and non-icemaking classes in the same equation, thus 
consolidating the presentation of classes and their energy conservation 
standards. The energy use equations will, for those classes that may or 
may not have an icemaker, include a term equal to the icemaking energy 
use adder multiplied by a factor that is defined to equal 1 for 
products with icemakers and to equal zero for products without 
icemakers. This approach does not combine classes that are the same 
other than the presence of an icemaker, but does simplify the list of 
classes and representation of their maximum allowable energy use, 
providing for each set of classes with and without ice makers a single 
equation for maximum energy use. (88 FR 12452)
    DOE is adopting the Joint Agreement proposal to express the maximum 
allowable energy use for any set of classes differing only in whether 
the class includes an icemaker or not within a single equation. The 
single equation does this by including the icemaker energy use adder 
multiplied by logical variable I that is set equal to 1 for a product 
with an icemaker present and 0 for a product without an icemaker.
b. Special Door and Multi-Door Designs
    The Joint Agreement made recommendations to establish new product 
classes for models that implement special and multi-door designs. The 
standards for these product classes include energy allowances (i.e., 
specific increases in maximum allowable energy use) corresponding to 
the specific performance-related features (i.e., door-in-door designs, 
transparent doors, and multi-door designs). The allowances include a 2-
percent energy use allowance for each externally opening door in excess 
of the typical minimum for the class, a 6-percent total energy use 
allowance for a product with a door-in-door feature implemented in one 
or more of its doors, and a 10-percent total energy use allowance for a 
product with a transparent door or doors.

[[Page 3042]]

    In this direct final rule, DOE is implementing the recommended 
special door and multi-door energy allowances. DOE's direct rulemaking 
authority under 42 U.S.C. 6295(p)(4) is constrained only by the 
requirements of 42 U.S.C. 6295(o), which does not include the product 
class requirements in 42 U.S.C. 6295(q). DOE is relying on the product 
classes provided in the Joint Agreement for consideration in this rule, 
but DOE notes that special doors (i.e., transparent doors and door-in-
door features) and multi-door setups constitute performance-related 
features that provide consumer utility when implemented. Transparent 
doors allow for partial view into the interior of fresh food 
compartments without the need for a door opening. Door-in-door features 
generally allow for access to a partially separated fresh food 
compartment without the need to fully expose the main interior fresh 
food compartment. Multi-door setups provide at least one additional 
externally opening door accessing either an existing compartment or a 
separate compartment, thus providing additional options for storage and 
access to food for the consumer.
    Furthermore, DOE's analysis of these features suggests that special 
door and multi-door designs impact energy usage with some combinations 
accounting for additional energy consumption of up to 25 percent (based 
on CERA simulations).\27\ DOE notes that the additional energy usage 
results from additional thermal load associated with additional gasket 
length necessary for multi-door and door-in-door features, and 
associated with the higher thermal conductivity of transparent doors 
compared to solid doors of the same size. DOE also proposed similar 
special door and multi-door energy allowances in the February 2023 NOPR 
and finds that the recommended allowances in the Joint Agreement are 
justifiable on a similar basis in light of the analysis DOE performed 
to develop the allowances proposed in the NOPR. See chapter 5 of the 
direct final rule TSD for more information on DOE's analysis of special 
door and multi-door features.
---------------------------------------------------------------------------

    \27\ CERA is an updated version of the Environmental Protection 
Agency's Refrigerator Analysis (``ERA'') program. Earlier versions 
have been used in previous refrigerator, refrigerator-freezer, and 
freezer energy conservation standards rulemaking. CERA allows for 
the simulation of thermal load on refrigerators, refrigerator-
freezers, and freezers based of the inputs given for various 
parameters including cabinet design, compartment dimensions, door 
design, operating temperatures, controls, anti-sweat heat, and more. 
More information regarding the software is found in the direct final 
rule TSD.
---------------------------------------------------------------------------

    For the reasons previously discussed, DOE is adopting the Joint 
Agreement recommendations to establish new product classes for models 
that implement special and multi-door designs.
Energy Use Allowance--Application
    AHAM, Sub Zero Group, Inc. (``Sub Zero''), and Samsung also 
recommended that DOE apply the door coefficient to PC 4, PC 4-BI, PC 9, 
and PC 9-BI, as these classes have products offering multi-door setups 
or special doors that provide similar customer utility. (AHAM, No. 69 
at p. 8; Sub Zero, No. 77 at p. 4; Samsung, No. 78 at p. 3) True 
Manufacturing (``TRUE'') similarly stated that PC 4I and PC 4, and any 
other product classes with transparent doors, should have the same 
transparent door allowance as PC 5A and PC 5. (TRUE, No. 57 at pp. 1-2)
    DOE's assessment regarding the energy impact of designs featuring 
multi-door and special door setups warranted the proposal of energy 
allowances for classes where such features are offered. DOE reviewed 
the market and requested input from commenters related to existing 
models on the market in an effort to assess the prevalence of multi-
door designs or special doors in products on the market today and 
concluded that there likely exist such models in PC 4I, PC 4I-BI, PC 9, 
and PC 9-BI that implement multi-door setups, special doors, or both. 
Therefore, DOE is adopting the multi-door and transparent door energy 
allowances for PC 4, PC 4I, PC 4-BI, PC 4I-BI, PC 9, and PC 9-BI 
consistent with feature availability. PC 4, PC 4I, PC 4-BI, and PC 4I-
BI will be eligible for transparent door and multi-door allowances, 
while PC 9, and PC 9-BI will be eligible for the multi-door allowance. 
The magnitude and application of the allowances adopted for the 
aforementioned product classes are consistent with those recommended in 
the Joint Agreement. DOE notes that PC 4 and PC 4-BI will be eligible 
for a 2 percent allowance for each additional door for products without 
a transparent door or door-in-door with added external doors, a 6 
percent allowance for products without a transparent door with a door-
in-door, or a 10 percent transparent door allowance for the use of a 
qualifying transparent door. PC 9 and PC 9-BI will be eligible for a 2 
percent allowance for each additional door up to two additional doors.
Energy Use Allowance--Definitions
    The Joint Agreement includes the following recommended definition 
for a transparent door:
    <bullet> Transparent door means a door for which 40 percent or more 
of the surface area--as determined based on the area of the transparent 
portion of the door divided by the product of the maximum width and 
height dimension of the door--is transparent to allow viewing into the 
refrigerated compartment.
    <bullet> Conceptually, the parties recommend that DOE clarify that 
products with only very small door or drawers that are transparent 
should not be included in this definition--i.e., the door must be large 
enough to justify the allowance.
    Upon further consideration of the February 2023 NOPR proposed 
transparent door definition, the feedback received from stakeholders, 
and the Joint Agreement submitted by interested parties, including 
AHAM, DOE conducted further market research into available models with 
transparent panels, generating a list of models from various 
manufacturers and product classes representative of the units currently 
on the market that implement transparent doors. From this list, DOE 
determined transparent panel and door area based on product literature, 
in-person measurements, or use of scaled photographs. DOE then 
determined the percentage of the door covered by the transparent area 
for each model considered. DOE found that the transparent door on a 
French door configuration typically had roughly 40 percent or more of 
the total outer door area transparent, consistent with the percentage 
recommended in the Joint Agreement. Other configurations, such as two 
door bottom-mount refrigerator-freezers and compact refrigerators had 
54 percent or more of their outer door area transparent. Based on this 
assessment and consideration of the Joint Agreement recommendations, 
DOE is adopting a modified definition from the February 2023 NOPR for 
transparent doors to better align with the products on the market, as 
follows:
    Transparent door means an external fresh food compartment door 
which meets the following criteria:
    <bullet> The area of the transparent portion of the door is at 
least 40 percent of the area of the door.
    <bullet> The area of the door is at least 50 percent of the sum of 
the areas of all the external doors providing access to the fresh food 
compartments and cooler compartments.
    <bullet> For the purposes of this evaluation, the area of a door is 
determined as the product of the maximum height and maximum width 
dimensions of the door, not considering potential extension of flaps 
used to provide a seal to adjacent doors.

[[Page 3043]]

    DOE notes that this amended transparent door definition not only 
aligns with the typical implementation on the market, as previously 
described, but also is a more straightforward approach compared to 
those recommended and referenced by commenters. Specifically, DOE 
expects that the suggested approach based on the internal cabinet 
dimensions has some potential for questions about interpretation, given 
the fact that the interior dimensions could vary from the front of the 
cabinet to the rear. This could lead to varying internal cabinet area 
determinations. Therefore, in order to eliminate this potential 
variation, DOE is adopting the above definition and approach that 
simplifies the determination of the transparent door area by measuring 
and determining the area of the transparent portion divided by the 
product of the maximum height and width dimensions of the door.
Energy Use Allowance--Summary
    In summary, in this direct final rule DOE is adopting the multi-
door and special door energy use allowances as proposed in the Joint 
Agreement, with the specified amendments as previously discussed.
c. Addition of Product Class 9A-BI
    The Joint Agreement recommends the addition of a new product class 
9A-BI (i.e., built-in upright freezers with automatic defrost and with 
through-the-door ice service) and specific energy efficiency standards 
for the new product class. The current energy conservation standards 
for freezers do not include a separate product class for products of 
this configuration, and DOE has not previously considered establishing 
a separate product class for them because it has not been aware of the 
existence of such products on the market, nor has it previously been 
notified by any manufacturer of the potential introduction of such a 
product. Under the current product class structure, any such product 
would most appropriately fit into current class 9I-BI (i.e., built-in 
upright freezers with automatic defrost with an automatic icemaker), 
since there is no class that fits this description and also has 
through-the-door ice service. Hence, in the absence of a product class 
for this configuration, such products would be subject to the current 
PC 9I-BI standards, which would, under the approach for designating 
classes and standards provided in this direct final rule, correspond to 
class grouping 9-BI with the icemaker variable I in the standards 
equation equal to 1, indicating addition of the 28 kWh/year icemaker 
energy use.
    Considering that the recommendation carries support from a broad 
cross-section of interests, including trade associations representing 
these manufacturers, environmental and energy-efficiency advocacy 
organizations, consumer advocates, and electric utility providers as 
well as the support of several States, DOE believes it appropriate to 
adopt this new product class, 9A-BI. DOE notes that the addition of a 
PC 9A-BI, as suggested by the Joint Agreement, is warranted as the 
application of a through-the-door icemaker constitutes a performance 
related feature with consumer utility and is likely to be introduced on 
the market in the near future.
    DOE notes the standard as recommended by the Joint Agreement for PC 
9A-BI is 5 percent higher than that of PC 9I-BI (built-in upright 
freezers with automatic defrost with an automatic icemaker). When 
considering class 9A-BI and 9I-BI, the key difference is the addition 
of through-the-door ice service, and the potential additional thermal 
load associated with its addition. Therefore, the 5 percent adjustment 
between 9I-BI and 9A-BI can be attributed mainly to the addition of 
through-the-door ice service. When comparing recommended standards to 
other product classes in which the key difference is the addition of 
through-the-door ice (i.e., 5I vs. 5A and 4I vs. 7), the 5 percent 
adjustment remains consistent with DOE's adopted standards. As a result 
of this consistency, DOE believes the recommended standard is 
appropriate in its application.
    Given the indication from the aforementioned stakeholders that such 
a product class standard would be beneficial in its implementation, the 
classification of through-the-door ice as a performance related 
feature, and the recommendation's consistency with the other adopted 
standards, DOE is adopting a PC 9A-BI standard in this direct final 
rule.
    See section V of this document for more information regarding the 
TSL configuration and discussion of the adopted level for this product 
class. See chapter 5 of the direct final rule TSD for more discussion 
regarding the addition of this product class.
2. Technology Options

identified 37 technology options initially determined to improve the 
efficiency of refrigerators, refrigerator-freezers, and freezers, as

------------------------------------------------------------------------

B. Screening Analysis

    DOE uses the following four screening criteria to determine which 
technology options are suitable for further consideration in an energy 
conservation standards rulemaking:
    (1) Technological feasibility. Technologies that are not 
incorporated in commercial products or in commercially viable, 
existing prototypes will not be considered further.
    (2) Practicability to manufacture, install, and service. If it 
is determined that mass production of a technology in commercial 
products and reliable installation and servicing of the technology 
could not be achieved on the scale necessary to serve the relevant 
market at the time of the projected compliance date of the standard, 
then that technology will not be considered further.
    (3) Impacts on product utility. If a technology is determined to 
have a significant adverse impact on the utility of the product to 
subgroups of consumers, or result in the unavailability of any 
covered product type with performance characteristics (including 
reliability), features, sizes, capacities, and volumes that are 
substantially the same as products generally available in the United 
States at the time, it will not be considered further.
    (4) Safety of technologies. If it is determined that a 
technology would have significant adverse impacts on health or 
safety, it will not be considered further.
    (5) Unique-pathway proprietary technologies. If a technology has 
proprietary protection and represents a unique pathway to achieving 
a given efficiency level, it will not be considered further, due to 
the potential for monopolistic concerns.

    10 CFR part 430, subpart C, appendix A, sections 6(b)(3) and 7(b).
    In summary, if DOE determines that a technology, or a combination 
of technologies, fails to meet one or more of the listed five criteria, 
it will be excluded from further consideration in the engineering 
analysis. The reasons for eliminating any technology are discussed in 
the following sections.
    The subsequent sections include comments from interested parties 
pertinent to the screening criteria, DOE's evaluation of each 
technology option against the screening analysis criteria, and whether 
DOE determined that a technology option should be excluded (``screened 
out'') based on the screening criteria.
1. Screened-Out Technologies
    In conducting the screening analysis for this direct final rule, 
DOE considered comments it had received in response to the screening 
analysis conducted for the February 2023 NOPR.
    In the February 2023 NOPR, DOE screened out the technologies 
presented in Table II.2 on the basis of technological feasibility, 
practicability to manufacture, install, and service, adverse impacts on 
utility or availability, adverse impacts on health and safety, and/or 
unique-pathway proprietary technologies.

    GEA recommended that DOE screen out ``improved resistivity of 
foam,'' which is primarily hydrofluoro-olefin (``HFO'') foams, as a 
technology option. GEA stated that HFO foams represent a unique and 
proprietary technology pathway and that the two listed by DOE in the 
February 2023 NOPR TSD--Solstice LBA and Ecomate--should be excluded 
through the technology screening analysis. GEA stated that Solstice 
LBA, an HFO foam blowing agent is only produced by a single 
manufacturer, Honeywell, and should therefore be screened out from 
consideration in DOE's technology assessment in this rulemaking. GEA 
noted that Ecomate has no proven commercialization in modern consumer 
refrigerators or freezers. (GEA, No. 75 at pp. 4-5)
    As discussed in the February 2023 NOPR, HFO foams are retained as a 
design option and passed the screening analysis because the technology 
option meets the five criteria previously mentioned. While GEA notes 
Ecomate has no proven commercialization in modern consumer 
refrigerators or freezer, as discussed in more detail in section 
3.4.2.1 of the February 2023 NOPR TSD, improved resistivity foams such 
as Solstice have been implemented in refrigerator-freezer models in the 
United States, as of at least 2014 \28\ and DOE has not received 
information regarding negative impacts to product utility or 
impracticability to manufacture or service products using improved 
resistivity foam. Some of the improved blowing agents reviewed by DOE 
(e.g., CO<INF>2</INF>) have been found to be non-flammable and lower in 
GWP than traditional insulation. DOE acknowledges that Solstice LBA is 
patented by Honeywell but included other potential technologies such as 
added carbon black and CO<INF>2</INF> blowing agents in its assessment. 
Therefore, as a technology option, DOE maintains that HFO foams meet 
the prerequisites to be included past the screening analysis. However, 
because DOE could not determine the type of foam used in the directly 
analyzed models from teardowns or based on the feedback from 
manufacturers, DOE found that there was an insufficient basis to 
implement this design option as a means to increase energy efficiency 
in either the February 2023 NOPR or this direct final rule analysis.

    An individual commented that microchannel condensers should not be 
retained as a design option, citing issues with implementation in the 
HVAC industry. The individual also stated that increased insulation 
thickness should not be retained as a design option, citing lessening 
of consumer utility. (Individual Commenter, No. 59 at p. 1)
    DOE has observed implementation of microchannel heat exchangers in 
PC 5I, PC 5A, and several built-in product classes. DOE has also 
received no information regarding negative impacts in consumer utility 
or safety, and therefore, DOE retained microchannel condensers as a 
design option in this analysis As with the HFO foam design option, 
while microchannel condensers passed the screening analysis, this 
design option was not included as a design pathway to achieve higher 
efficiency levels in the direct final rule analysis due to potential 
system operation drawbacks including irregular refrigerant 
distribution, greater refrigerant-side pressure drop, and greater air-
side pressure drop.\29\

---------------------------------------------------------------------------

    DOE expects that increased insulation thickness would impact either 
the interior or exterior dimensions of a refrigerator, refrigerator-
freezer, or freezer, and as a result did not consider increased 
insulation thickness as a design option to achieve the higher 
efficiency levels for standard-size refrigerator-freezers. However, DOE 
expects that there is potential to increase insulation thickness for 
some types of freezers and compact refrigerators, given their typical 
use in in spaces that allow increased exterior dimensions, and 
therefore continues to consider increased thickness as a design option 
to achieve higher efficiency levels for PC 10, PC 11A, and PC 18.
2. Remaining Technologies
    Through a review of each technology, DOE concludes that all of the 
other identified technologies listed in section IV.B.1 met all five 
screening criteria to be examined further as design options in DOE's 
direct final rule analysis. In summary, DOE did not screen out the 
following technology options:

       Table IV.3--Technologies Remaining in the Direct Final Rule
------------------------------------------------------------------------
 
-------------------------------------------------------------------------
Insulation:
    1. Improved resistivity of insulation (insulation type.
    2. Increased insulation thickness.
    3. Gas-filled insulation panels.
    4. Vacuum-insulated panel.
Gasket and Door Design:
    5. Reduced heat load for TTD feature.
Anti-Sweat Heater:
    6. Refrigerant anti-sweat heating.
    7. Electric anti-sweat heater sizing.
    8. Electric heater controls.
Compressor:
    9. Improved compressor efficiency.
    10. Variable-speed compressors.

    11. Improved expansion valve.

    12. Increased surface area.
    13. Dual-evaporator systems.
Condenser:
    14. Increased surface area.
    15. Microchannel condenser.
Defrost System:
    16. Reduced energy for automatic defrost.
    17. Adaptive defrost.
Control System:
    18. Electronic Temperature control.
Other Technologies:
    19. Fan and fan motor improvements.
    20. Alternative refrigerants.
------------------------------------------------------------------------

    DOE determined that these technology options are technologically 
feasible because they are being used or have previously been used in 
commercially available products or working prototypes. DOE also finds 
that all of the remaining technology options meet the other screening 
criteria (i.e., practicable to manufacture, install, and service and do 
not result in adverse impacts on consumer utility, product 
availability, health, or safety). For additional details, see chapter 4 
of the direct final rule TSD.

C. Engineering Analysis

    The purpose of the engineering analysis is to establish the 
relationship between the efficiency and cost of refrigerators, 
refrigerator-freezers, and freezers. There are two elements to consider 
in the engineering analysis: the selection of efficiency levels to 
analyze (i.e., the ``efficiency analysis'') and the determination of 
product cost at each efficiency level (i.e., the ``cost analysis''). In 
determining the performance of higher-efficiency products, DOE 
considers technologies and design option combinations not eliminated by 
the screening analysis. For each product class, DOE estimates the 
baseline cost, as well as the incremental cost for the product/
equipment at efficiency levels above baseline. The output of the 
engineering analysis is a set of cost-efficiency ``curves'' that are 
used in downstream analyses (i.e., the LCC and PBP analyses and the 
NIA).
1. Efficiency Analysis
    DOE typically uses one of two approaches to develop energy 
efficiency levels for the engineering analysis: (1) relying on observed 
efficiency levels in the market (i.e., the efficiency-level approach), 
or (2) determining the incremental efficiency improvements associated 
with incorporating specific design options to a baseline model (i.e., 
the design option approach). Using the efficiency-level approach, the 
efficiency levels established for the analysis are determined based on 
the market distribution of existing products (in other words, based on 
the range of efficiencies and efficiency level ``clusters'' that 
already exist on the market). Using the design option approach, the 
efficiency levels established for the analysis are determined through 
detailed engineering calculations and/or computer simulations of the 
efficiency improvements from implementing specific design options that 
have been identified in the technology assessment. DOE may also rely on 
a combination of these two approaches. For example, the efficiency-
level approach (based on actual products on the market) may be extended 
using the design option approach either to establish ``gap fill'' 
levels (to bridge large gaps between other identified efficiency 
levels) and/or to extrapolate to the ``max-tech'' level (particularly 
in cases where the ``max-tech'' level exceeds the maximum efficiency 
level currently available on the market).
    In defining the efficiency levels for this direct final rule, DOE 
considered comments it had received in response to the efficiency 
levels proposed in the February 2023 NOPR.
    For its analysis in this rulemaking, DOE used a combined efficiency 
level and design option approach. First, an efficiency-level approach 
was used to establish an analysis tied to existing products on the 
market. A design option approach was used to extend the analysis 
through ``built-down'' efficiency levels and ``built-up'' efficiency 
levels where there were gaps in the range of efficiencies of products 
that were reverse engineered. Products from PC 3, PC 5, PC 5A, PC 5-BI, 
PC 7, PC 9, PC 10, PC 11A, and PC 18 were tested and torn down to 
provide information to lay the groundwork for the analysis. Other 
product classes such as 9-BI (and the new PC 9A-BI recommended by the 
Joint Agreement) were not directly analyzed as a part of DOE's 
analysis, as they were not deemed sufficiently representative of the 
market. A number of other product classes were indirectly analyzed, 
based on relevant directly analyzed product classes. DOE's analysis for 
PC-9BI, for example, is based on the directly analyzed PC 9.
    DOE used design option analysis techniques to extend the analysis 
to higher efficiency levels and to fill any efficiency level gaps. DOE 
generally focuses its analysis on product classes with higher market 
share as their energy impact and associated energy savings are the most 
significant. Therefore, for this direct final rule analysis DOE chose 
to test and teardown units from the product classes listed above that 
represent a significant market share, and extrapolated the analysis to 
all other product classes that were not directly analyzed, as 
appropriate.
a. Built-In Products
    For the analysis supporting this direct final rule, DOE used an 
assessment of PC 5-BI (built-in refrigerator-freezer with bottom-
mounted freezer) to address built-in products. DOE conducted analysis 
for a representative 5-BI product and compared it to analysis conducted 
for freestanding models of class 5. DOE concluded that a built-in model 
that is comparable to a freestanding model except the built-in 
configuration would have 5 percent higher energy use. Therefore, for 
example, the potential reduction in energy use for built-in PC 5 units 
would be 5 percent lower than their freestanding counterparts, based on 
the implementation of the same design options to satisfy a higher 
efficiency level. DOE has applied this 5-percent differential in 
selecting standard levels for other built-in classes for which DOE did 
not conduct direct analysis (e.g., PC 3A, PC 7, and PC 9). More 
information on the analysis of built-in product classes is available in 
the direct final rule TSD.

[[Page 3047]]

b. Baseline Efficiency/Energy Use
    For each product/equipment class, DOE generally selects a baseline 
model as a reference point for each class, and measures changes 
resulting from potential energy conservation standards against the 
baseline. The baseline model in each product/equipment class represents 
the characteristics of a product/equipment typical of that class (e.g., 
capacity, physical size). Generally, a baseline model is one that just 
meets current energy conservation standards, or, if no standards are in 
place, the baseline is typically the most common or least efficient 
unit on the market. When selecting units for the analysis DOE selects 
units at baseline from various manufacturers for each directly analyzed 
product class.
    In determining the baseline efficiency level for this direct final 
rule analysis, DOE maintained the same approach as the February 2023 
NOPR, and considered the current Federal energy conservation standards 
as the baseline level, expressed as maximum annual energy consumption 
as a function of the product's adjusted volume, adjusting for the 
change in the automatic icemaker energy contribution for product 
classes that include this feature. The current standards incorporate an 
allowance of a constant 84 kWh/yr icemaker adder for product classes 
with automatic icemakers, consistent with the current test procedure, 
which requires adding this amount of annual energy use to the product's 
tested performance if the product has an automatic icemaker. DOE 
adjusted the baseline energy usage levels for each class to account for 
the planned revision in the test procedure to reduce the icemaker 
energy use adder to 28 kWh/yr.\30\

for refrigeration products for more information regarding the 
adoption of the 28 kWh/yr icemaker adder. 86 FR 56790.
---------------------------------------------------------------------------

    DOE directly analyzed a sample of market representative models from 
within nine product classes from multiple manufactures. For most 
product classes a single representative adjusted volume was analyzed, 
though for PC 3, PC 5, and PC 11, DOE directly analyzed two 
representative adjusted volumes within the product class. DOE tested 
and tore down 13 baseline units to provide a basis for development of 
the cost-efficiency curves. DOE's analysis assumed that all baseline 
models implement R-600a refrigerant, based on feedback during 
manufacturer interviews suggesting the industry has or is in the 
process of shifting to low-GWP refrigerants, in particular away from R-
134a, in accordance with regulatory efforts to phasedown of 
hydrofluorocarbons.\31\ Further information on the design 
characteristics of specific analyzed baseline models is summarized in 
the direct final rule TSD.

for more information regarding the environmental protection agency's 
final rule regarding the phasedown of hydrofluorocarbons.
---------------------------------------------------------------------------

    BSH disagreed with DOE's use of HFO foam as representative of a 
baseline refrigerator, refrigerator-freezer, and/or freezer's 
insulation in the February 2023 NOPR, citing high environmental impact 
of the insulation, and encouraged DOE to remove HFO foam from baseline 
analysis. (BSH, No. 64 at pp. 1-2) AHAM also suggested that considering 
HFO foam at baseline efficiency levels is inappropriate and result in 
an artificially high baseline efficiency, excessively stringent 
standards for high-volume product classes, and negative environmental 
impacts. (AHAM, No. 69 at pp. 4-5)
    DOE was unable to determine the type of insulation used in teardown 
models and subsequently considered PU insulation at the baseline level 
for all product classes in the February 2023 NOPR and in this direct 
final rule. Furthermore, as described in section IV.B.2 of this 
document, DOE retained the improved insulation resistivity design 
option (i.e., HFOs) through the screening analysis, though DOE did not 
utilize it as a design to achieve higher efficiency levels in the 
engineering analysis. DOE further notes, that BSH and AHAM are parties 
to the Joint Agreement and are supportive of the recommended standard 
adopted in this direct final rule.
c. Higher Efficiency Levels
    For this direct final rule, DOE maintained the same approach as the 
February 2023 NOPR, and analyzed up to five incremental efficiency 
levels beyond the baseline for each of the analyzed product classes. 
For PC 3 and PC 7, DOE considered an efficiency level at roughly 5 
percent more efficient than the current energy conservation standard. 
For all product classes, DOE considered a level near 10 percent more 
efficient than the current energy conservation standard, equivalent to 
the current ENERGY STAR[supreg] level for refrigerators, refrigerator-
freezers, and freezers.\32\ DOE then extended the efficiency levels 
(``ELs'') in steps of close to 5 percent of the current energy 
conservation standard up to EL 4, using applicable technologies as 
discussed in sections IV.A.2 and IV.B of this document. Finally, for 
all product classes, EL 5 represents ``max-tech,'' using design option 
analysis to extend the analysis beyond EL 4 using all applicable design 
options, including the most efficient variable-speed compressors 
available on the market, and considerable use of vacuum-insulated 
panels (``VIPs'') in key areas of the cabinet walls and doors. The 
efficiency levels analyzed beyond the baseline are shown in Table IV.4.

d. VIP Analysis and Max-Tech Levels
---------------------------------------------------------------------------

    \33\ DOE notes the recommended TSL for this direct final rule is 
TSL 4, discussed further in section V.A of this document.
---------------------------------------------------------------------------

    As discussed in the previous section, DOE's NOPR analysis 
considered the use of VIPs placed throughout the side walls and doors 
at max-tech levels for many product classes.
    AHAM disagreed with the extent of VIP use at higher efficiency 
levels in the engineering analysis, asserting that DOE overestimates 
the use and impact of VIPs in its analysis, despite acknowledging the 
technology's limitations. AHAM cited panel cost, in the form of labor 
and production costs, which are significant due to complex installation 
requirements, processing controls, and quality checks. AHAM also cited 
lower effectiveness in smaller units due to ``edge effects'' (i.e., 
heat around the edges caused by the membrane film that forms the walls 
of the VIP). AHAM suggested that DOE not overestimate the impact of 
VIPs in its analysis, considering that VIPs are not used in a majority 
of products and manufacturers have reported varied levels of success 
using the technology. (AHAM, No. 69 at pp. 5-6)
    DOE's implementation of VIPs in the analyses at each stage of this 
rulemaking is based on a combination of the best information gathered 
from multiple sources related to cost, use, and energy efficiency 
impacts. DOE did not specifically account for edge effect impacts on 
thermal load for compact refrigerator, refrigerator-freezer, or freezer 
models in its analysis. Regarding VIP pricing, DOE estimated VIP panel, 
installation, processing, and quality check costs based on a number of 
discussions with refrigerator manufacturers, VIP producers, and market 
research. DOE conducted additional interviews and research in support 
of this direct final rule, which further supported and solidified the 
VIP cost estimates.
    In manufacturer interviews, DOE also gathered information regarding 
the implementation of VIPs (e.g., locations, number of panels, panel 
area), and based on that information, DOE performed simulations to 
estimate the energy impacts using CERA. CERA allowed DOE to analyze the 
thermal load impact on a fresh food and/or freezer cabinet due to 
different placements of VIP paneling throughout a cabinet (e.g., side 
panels, doors, or both). DOE then compared the results from these 
simulations to existing research into load reductions (which estimates 
energy savings at around 30 percent) \34\ and based on both sources, 
estimated that the full implementation of VIPs in existing cabinets can 
reduce heat load by up to 23 percent. DOE did not specifically account 
for edge effect impacts on thermal load for compact refrigerator, 
refrigerator-freezer, or freezer models in its analysis. However, DOE 
notes that the engineering analysis halves the thermal load impact as 
observed in simulations in order to be conservative with energy savings 
and to account for factors that are not captured in testing and/or 
simulation (e.g., differences in VIP core material, VIP installation 
method and location). DOE also notes VIPs are not implemented in most 
classes until efficiency levels above that proposed in the February 
2023 NOPR and adopted in this direct final rule.

Vacuum-Insulated Panels (VIPs),'' European Commission, January 2017.

---------------------------------------------------------------------------

    Sub Zero commented that as a small, low-volume manufacturer of 
niche built-in style refrigeration products, it is concerned that the 
standards proposed in the February 2023 NOPR will create a significant 
supply chain burden for them, as components like vacuum insulation 
panels are supplied by a limited number of manufacturers, which will 
impede their ability to deliver products to their consumers in a timely 
manner. Sub Zero requested that DOE reduce the stringency level of 
adopted standards for built-in products, to reduce these concerns. (Sub 
Zero, No. 77 at p. 2)
    To better characterize and understand the VIP market, DOE conducted 
research and interviewed relevant VIP manufacturers to gather more data 
regarding the current global VIP market, and to identify any potential 
supply chain constraints related to the adoption of more stringent 
energy conservation standards. DOE estimates that the current demand 
for VIPs in the U.S. refrigerator market is roughly 1 to 3 million VIP 
panels, whereas the global supply for VIPs is estimated to exceed 10 
million panels. Despite relatively low demand for VIPs in the U.S. 
market, there is notable VIP use in the European and Asian markets, 
with supply available from at least three major VIP manufacturers. 
Based on the information gathered, DOE expects that VIP production 
lines can be quickly scaled up to meet demand of future amended 
standards (within 1 to 2 years depending on the specific VIP design), 
well within 3-year lead time between publication of amended standards 
and the compliance date for those standards.
    In response to stakeholder feedback on the February 2023 NOPR, DOE 
carefully considered the use of VIPs in its analysis, generally 
implementing VIPs at the highest efficiency levels as one of the last 
design options considered. Therefore, based on the engineering analysis 
and its consideration of VIPs, DOE expects that to meet the adopted 
standards, manufacturers are likely to implement VIPs only in PC 5 (for 
three-door, 30 AV configuration) and PC 5A, with partial VIP usage for 
both classes.
e. Variable-Speed Compressor Supply Chain
    Numerous commenters on the February 2023 NOPR suggested that supply 
chains for VIPs and variable-speed compressor (``VSC'') may not support 
the quantities of those components that may be required at the 
efficiency levels proposed in the NOPR. AHAM recommended that DOE 
conduct a review of component availability and supply chain capacity 
for VSCs given the general global market trends for increasingly 
stringent standards for cooling appliances, including both air 
conditioning and refrigeration. (AHAM, No. 69 at p. 5) Whirlpool 
further noted that the proposed standards may result in increased 
component costs to manufacturers due to those same supply chain 
constraints, especially given that VSCs would be necessary for nearly 
all evaluated product classes. (Whirlpool, No. 70 at p. 5) Sub Zero 
also expressed concern that the proposed standards will create a 
significant supply chain burden for small, low-volume manufacturer of 
niche market built-in style refrigeration products because VSCs are 
provided by a limited number of suppliers. Sub Zero commented that the 
proposed standards will impede the ability of these small manufacturers 
to deliver to their niche consumers in a timely manner. (Sub Zero, No. 
77 at p. 2)
    Samsung supported DOE's proposed energy conservation standards for 
refrigerators, refrigerator-freezers, and freezers and the use of VSC 
technology as a significant energy-saving option. Samsung stated that 
there is already significant market availability of VSCs, and a 
regulatory certainty and 3-year compliance period would provide ample 
time for manufacturers and suppliers to establish sufficient supply 
availability of VSCs. (Samsung, No. 78 at p. 2)
    In response to these comments, DOE interviewed relevant compressor 
manufacturers to gather information

[[Page 3050]]

regarding the level of VSC implementation that would be required at the 
efficiency levels in this rule, the current and predicted supply of 
VSCs into the U.S. market, the predicted time to ramp up production of 
VSCs, and pricing of VSC compressors and components. DOE notes that the 
VSC compressors focused on in this supply chain analysis differ from 
those utilized in air conditioners and other non-related cooling 
appliances. VSC compressors utilized in refrigerators, refrigerator-
freezers, and freezers are generally different designs, are 
manufactured in different factories, and are generally produced by 
different manufacturers. Thus, based on the information provided by 
these manufacturers, DOE has determined that the industry is able to 
meet the increased demand of VSCs amid likely growing demand in the 
U.S. market.
    Based on manufacturer interviews, DOE estimates the current total 
global demand for refrigerator, refrigerator-freezer, and freezer 
compressors (all compressors, not just VSCs) is 230 million. Total 
compressor production capacity is much higher than demand, with global 
capacity for compressors estimated at over 400 million. Globally, there 
has been a shift towards VSC utilization in response to increasing 
energy efficiency regulations in the European Union (``EU'') and Japan. 
Estimates project upwards of a quarter of the global market and a third 
of the U.S. market currently utilize VSCs in refrigerators, 
refrigerator-freezers, and freezers. Considering the U.S. market 
accounts for an estimated 12 million consumer refrigeration products, a 
conservative estimate puts U.S. current demand for VSC compressors at 
roughly 4 million.
    Given DOE's understanding of the compressor marketplace, the 
expected time to build capacity to meet the new demand is expected to 
be significantly shorter than the 5 and 6-year lead time between direct 
final rule publication and the compliance date, with estimates ranging 
from 8 months to 1 year. Compressor manufacturers indicated that VSC 
production capacity has been increasing by 7 million per year between 
2018 and 2022. Additionally, high-efficiency VSC compressor designs are 
already developed and do not require additional qualification testing 
before production. Research and development (``R&D'') time to develop 
compressor designs is not required and thus would not be a factor 
affecting availability.
    DOE is aware that there have been supply constraints for VSCs 
recently due to issues with electronic component supply caused by the 
COVID-19 pandemic. Specifically, Chinese manufacturing and shipping of 
compressors decreased significantly during COVID-related lockdowns 
throughout the country between 2020 and 2022. Due to China's outsized 
impact on global supply, the effects of lockdowns were felt globally. 
Now that lockdowns have ended, however, the affected factories are open 
again and in production. Compressor manufacturers also indicated that 
they have been modifying sourcing strategies, in many cases 
establishing their own electronic component assembly lines in order to 
protect against potential future issues that could affect supply and 
production of VSCs.
    In considering all of the information provided by relevant 
manufacturers of VSCs, DOE believes that significant increases in VSCs 
in the U.S. market aligned with the standard levels adopted in this 
direct final rule are well within the production capacity of the 
compressor industry. DOE further notes, that AHAM, Whirlpool, Sub Zero, 
and Samsung are parties to the Joint Agreement and are supportive of 
the recommended standard adopted in this direct final rule.
f. Product Classes 11 and 12 Alignment
    The Joint Agreement recommended that DOE adopt a level of 10 
percent energy savings relative to the current PC 12 standard. In light 
of the recommendation outlined in the Joint Agreement, and in 
consideration of comments received in response to the February 2023 
NOPR, DOE is adopting a percentage increase in efficiency for PC 12 at 
10 percent lower relative to the current standard. Additionally, as 
recommended in the Joint Agreement and proposed in the February 2023 
NOPR, DOE is including a multi-door energy use allowance for PC 12 for 
products with two doors.
2. Cost Analysis
    The cost analysis portion of the engineering analysis is conducted 
using one or a combination of cost approaches. The selection of cost 
approach depends on a suite of factors, including the availability and 
reliability of public information, characteristics of the regulated 
product, the availability and timeliness of purchasing the product on 
the market. The cost approaches are summarized as follows:
    <bullet> Physical teardowns: Under this approach, DOE physically 
dismantles a commercially available product, component-by-component, to 
develop a detailed bill of materials for the product.
    <bullet> Catalog teardowns: In lieu of physically deconstructing a 
product, DOE identifies each component using parts diagrams (available 
from manufacturer websites or appliance repair websites, for example) 
to develop the bill of materials for the product.
    <bullet> Price surveys: If neither a physical nor catalog teardown 
is feasible (for example, for tightly integrated products such as 
fluorescent lamps, which are infeasible to disassemble and for which 
parts diagrams are unavailable) or cost-prohibitive and otherwise 
impractical (e.g., large commercial boilers), DOE conducts price 
surveys using publicly available pricing data published on major online 
retailer websites and/or by soliciting prices from distributors and 
other commercial channels.
    In the direct final rule analysis, DOE conducted the analysis using 
a combination of physical teardowns, catalog teardowns, and price 
surveys. Where possible, physical teardowns were used to provide a 
baseline of technology options and pricing for a specific product class 
at a specific EL. Then with technology option information, DOE 
estimated the cost of various design options including compressors, 
VIPs, and insulation, by extrapolating the costs from price surveys. 
With specific costs for technology options, DOE was then able to 
``build-up'' or ``build-down'' from the various teardown models to 
finish the cost-efficiency curves. DOE used this approach to calibrate 
the analysis to certified or measured energy use of specific available 
models where possible, while allowing a broader range of potential 
efficiency levels to be considered.
    The resulting bill of materials provides the basis for the 
manufacturer production cost (``MPC'') estimates.
    To account for manufacturers' non-production costs and profit 
margin, DOE applies a multiplier (the manufacturer markup) to the MPC. 
The resulting manufacturer selling price (``MSP'') is the price at 
which the manufacturer distributes a unit into commerce. DOE developed 
an average manufacturer markup by examining the annual Securities and 
Exchange Commission (``SEC'') 10-K reports filed by publicly traded 
manufacturers primarily engaged in appliance manufacturing and whose 
combined product range includes refrigerators, refrigerator-freezers, 
and freezers.
3. Cost-Efficiency Results
    The results of the engineering analysis are presented as cost-
efficiency data for each of the efficiency levels for each of the 
analyzed product classes that were

[[Page 3051]]

analyzed. DOE developed estimates of MPCs for each unit in the teardown 
sample, and also performed additional modeling based on representative 
teardown samples, to extend the analysis to cover the range of 
efficiency levels appropriate for a representative product. To estimate 
the MPCs necessary to achieve higher efficiency levels, in particular 
those beyond the highest-efficiency products in the test sample, DOE 
considered design options that were most likely to be considered and 
implemented by manufacturers to achieve the higher efficiency levels. 
Based on input from manufacturers and an understanding of the markets, 
DOE then estimated the costs associated with those design option to 
determine the MPCs at each of the analyzed efficiency levels.
    The efficiency levels and design option progression for the 
analyzed standard-size refrigerator-freezers are presented in Table 
IV.5. The cells in the table list the design options that DOE 
considered at each higher efficiency level as compared with the next-
lower efficiency level. Similarly, the efficiency levels and design 
options for standard-size freezers and Compact refrigerators, 
refrigerator-freezers are presented in Table IV.6. The MPCs for the 
analyzed product classes across the considered efficiency levels are 
presented in Tables IV.7 and IV.8. See chapter 5 of the direct final 
rule TSD for additional detail on the engineering analysis.

4. Manufacturer Selling Price
    To account for manufacturers' non-production costs and revenue 
attributable to the product, DOE applies a multiplier (the manufacturer 
markup) to the MPC. The resulting manufacturer selling price (``MSP'') 
is the price at which the manufacturer distributes a unit into 
commerce. DOE developed an average manufacturer markup by examining the 
annual Securities and Exchange Commission (``SEC'') 10-K reports \35\ 
filed by publicly traded manufacturers primarily engaged in appliance 
manufacturing and whose combined product range includes refrigerators, 
refrigerator-freezers, and freezers. See chapter 12 of the direct final 
rule TSD for additional detail on the manufacturer markup.

Gathering, Analysis, and Retrieval (EDGAR) system. Available at 
www.sec.gov/edgar/search/ (last accessed July 1, 2022).
---------------------------------------------------------------------------

D. Markups Analysis

    The markups analysis develops appropriate markups (e.g., retailer 
markups, wholesaler markups, contractor markups) in the distribution 
chain and sales taxes to convert the MSP estimates derived in the 
engineering analysis to consumer prices, which are then used in the LCC 
and PBP analysis. At each step in the distribution channel, companies 
mark up the price of the product to cover business costs and operating 
profit.
    For refrigerators, refrigerator-freezers, and freezers, the main 
parties in the distribution chain are retailers, wholesalers, and 
general contractors.
    DOE developed baseline and incremental markups for each actor in 
the distribution chain. Baseline markups are applied to the price of 
products with baseline efficiency, while incremental markups are 
applied to the difference in price between baseline and higher-
efficiency models (the incremental cost increase). The incremental 
markup is typically less than the baseline markup and is designed to 
maintain similar per-unit operating profit before and after new or 
amended standards.\36\
---------------------------------------------------------------------------

    \36\ Because the projected price of standards-compliant products 
is typically higher than the price of baseline products, using the 
same markup for the incremental cost and the baseline cost would 
result in higher per-unit operating profit. While such an outcome is 
possible, DOE maintains that in markets that are reasonably 
competitive it is unlikely that standards would lead to a 
sustainable increase in profitability in the long run.
---------------------------------------------------------------------------

    DOE relied on economic data from the U.S. Census Bureau to estimate 
average baseline and incremental markups. Specifically, DOE used the 
2017 Annual Retail Trade Survey for the ``electronics and appliance 
stores'' sector to develop retailer markups,\37\ the 2017 Annual 
Wholesale Trade Survey for the ``household appliances, and electrical 
and electronic goods merchant wholesalers'' sector to estimate 
wholesaler markups,\38\ and the industry series for the ``residential 
building construction'' sector published by the 2017 Economic Census to 
derive general contractor markups.\39\ DOE relied on economic data from 
the U.S. Census Bureau to estimate average baseline and incremental 
markups. Specifically, DOE used the 2017 Annual Retail Trade Survey for 
the ``electronics and appliance stores'' sector to develop retailer 
markups,\40\ the 2017 Annual Wholesale Trade Survey for the ``household 
appliances, and electrical and electronic goods merchant wholesalers''

Economic Census to derive general contractor markups.\42\

---------------------------------------------------------------------------

    In response to the February 2023 NOPR, AHAM commented on DOE's 
reliance on the concept of incremental markups, stating that it is 
based on discredited theory, and it is in contradiction to empirical 
evidence provided by AHAM during the 2014

[[Page 3054]]

NOPR for Energy Conservation Standards for Residential Dishwashers. 
(AHAM, No. 69 at p. 15-16)
    DOE disagrees that the theory behind the concept of incremental 
markups is discredited. DOE's incremental markup approach assumes that 
an increase in profitability, which is implied by keeping a fixed 
markup when the product price goes up, is unlikely to be viable over 
time in a reasonably competitive market like household appliance 
retailers. The Herfindahl-Hirschman Index (HHI) reported by the 2017 
Economic Census indicates that household appliance stores sector (North 
American Industry Classification System (NAICS) code 443141) is a 
competitive marketplace.\43\ DOE recognizes that actors in the 
distribution chains are likely to seek to maintain the same markup on 
appliances in response to changes in manufacturer selling prices after 
an amendment to energy conservation standards. However, DOE believes 
that retail pricing is likely to adjust over time as those actors are 
forces to readjust their markups to reach a medium-term equilibrium in 
which per-unit profit is relatively unchanged before and after 
standards are implemented.

    DOE acknowledges that markup practices in response to amended 
standards are complex and varying with business conditions. However, 
DOE's analysis necessarily considers a very simplified and hypothetical 
version of the world of appliance retailing: namely, a situation in 
which nothing changes except for those changes in appliance offerings 
that occur in response to amended standards. Obtaining data on markup 
practices in the situation described above is very challenging. Hence, 
DOE continues to believe that its assumption that standards do not 
facilitate a sustainable increase in profitability is reasonable.
    Chapter 6 of the direct final rule TSD provides details on DOE's 
development of markups for refrigerators, refrigerator-freezers, and 
freezers.

E. Energy Use Analysis

    The purpose of the energy use analysis is to determine the annual 
energy consumption of refrigerators, refrigerator-freezers, and 
freezers at different efficiencies in representative U.S. single-family 
homes, multi-family residences, and commercial buildings, and to assess 
the energy savings potential of increased product efficiency. The 
energy use analysis estimates the range of energy use of refrigerators, 
refrigerator-freezers, and freezers in the field (i.e., as they are 
actually used by consumers). The energy use analysis provides the basis 
for other analyses DOE performed, particularly assessments of the 
energy savings and the savings in consumer operating costs that could 
result from adoption of amended or new standards.
    The DOE test procedure produces standardized results that can be 
used to assess or compare the performance of products operating under 
specified conditions. Actual energy usage in the field often differs 
from that estimated by the test procedure because of variation in 
operating conditions, the behavior of users, and other factors. In the 
case of refrigerators, refrigerator-freezers, and freezers, DOE used 
usage adjustment factors (UAFs) in the February 2023 NOPR to address 
the difference in field-metered energy consumption and the DOE test 
results due to household-specific characteristics. 88 FR 12478-12479.
    Specifically, DOE combined field-metered energy use data for full-
size refrigeration products from the September 2011 Final Rule, the 
Northwest Energy Efficiency Alliance (``NEEA''), and the Florida Solar 
Energy Center (``FSEC'') with estimates of the test energy use of each 
field-metered unit. Then, DOE calculated a unit's UAF by dividing the 
annual field-metered energy use by the annual energy consumption from 
the DOE test procedure. DOE then used maximum likelihood estimation to 
fit log-normal distributions to the empirical distributions of UAFs for 
primary refrigerators and refrigerator-freezers, secondary 
refrigerators and refrigerator-freezers, and freezers. DOE sampled UAFs 
from these fitted log-normal distributions to estimate the actual 
energy use of refrigeration products for the consumer sample. DOE did 
not have adequate field-metering data to derive UAFs for compact 
refrigeration products; therefore, DOE assumed the UAF of compact 
refrigeration products was 1.0.
    In response to the February 2023 NOPR, AHAM commented that DOE 
relies heavily on the EIA's Residential Energy Consumption Survey 
(``RECS'') data for estimating energy use and how consumption varies at 
the household level. Specifically, AHAM expressed concern that the use 
of RECS data to estimate energy consumption at the household level may 
introduce ``outlier values,'' resulting in uncertainty and inaccuracies 
(AHAM, No. 69 at pp. 17-18) In this direct final rule, as well as in 
the February 2023 NOPR, DOE did not tie the energy consumption of 
refrigerators, refrigerator-freezers, and freezers to RECS survey data. 
88 FR 12452. No household or demographic information from RECS affects 
the energy consumption of a particular household. Instead, as mentioned 
above, DOE sampled from distributions of UAFs that were derived from 
field-metering studies and assigned a randomly selected UAF to each 
household. Randomly sampling from distributions of UAFs acknowledges 
the inherent uncertainty in estimating the energy use for any 
particular household, while capturing the aggregate impact of UAFs 
measured in the field, and thus better approximates the most likely 
distribution of field energy use values across the installed base of 
products than relying strictly on survey data. DOE further notes, that 
AHAM is a party to the Joint Agreement and is supportive of the 
recommended standard adopted in this direct final rule.
    Chapter 7 of the direct final rule TSD provides details on DOE's 
energy use analysis for refrigerators, refrigerator-freezers, and 
freezers.

F. Life-Cycle Cost and Payback Period Analysis

    DOE conducted LCC and PBP analyses to evaluate the economic impacts 
on individual consumers of potential energy conservation standards for 
refrigerators, refrigerator-freezers, and freezers. The effect of new 
or amended energy conservation standards on individual consumers 
usually involves a reduction in operating cost and an increase in 
purchase cost. DOE used the following two metrics to measure consumer 
impacts:
    <bullet> The LCC is the total consumer expense of an appliance or 
product over the life of that product, consisting of total installed 
cost (manufacturer selling price, distribution chain markups, sales 
tax, and installation costs) plus operating costs (expenses for energy 
use, maintenance, and repair). To compute the operating costs, DOE 
discounts future operating costs to the time of purchase and sums them 
over the lifetime of the product.
    <bullet> The PBP is the estimated amount of time (in years) it 
takes consumers to recover the increased purchase cost (including 
installation) of a more efficient product through lower operating 
costs. DOE calculates the PBP by dividing the change in purchase cost 
at higher efficiency levels by the change in annual operating cost for 
the year that amended or new standards are assumed to take effect.
    For any given efficiency level, DOE measures the change in LCC 
relative to

[[Page 3055]]

the LCC in the no-new-standards case, which reflects the estimated 
efficiency distribution of refrigerators, refrigerator-freezers, and 
freezers in the absence of new or amended energy conservation 
standards. In contrast, the PBP for a given efficiency level is 
measured relative to the baseline product.
    For each considered efficiency level in each product class, DOE 
calculated the LCC and PBP for a nationally representative set of 
housing units (all product classes) and commercial buildings (PC 11A 
only). DOE included commercial applications in the analysis of compact 
refrigerators and refrigerator-freezers (PC 11A) because they are used 
in both the residential and commercial sectors (e.g., hotel rooms and 
higher-education dormitories). DOE developed household samples from the 
2020 RECS and commercial building samples from the 2018 Commercial 
Buildings Energy Consumption Survey (``CBECS''). For each sample 
household or building, DOE determined the energy consumption for the 
refrigerator, refrigerator-freezer, or freezer and the appropriate 
electricity price and discount rate. By developing a representative 
sample of households and buildings, the analysis captured the 
variability in energy consumption, energy prices, and discount rates 
associated with the use of refrigerators, refrigerator-freezers, and 
freezers.
    Inputs to the calculation of total installed cost include the cost 
of the product--which includes MPCs, manufacturer markups, distribution 
chain markups, and sales taxes--and installation costs. Inputs to the 
calculation of operating expenses include annual energy consumption, 
energy prices and price projections, repair and maintenance costs, 
product lifetimes, and discount rates. DOE created distributions of 
values for product lifetime, discount rates, and sales taxes, with 
probabilities attached to each value, to account for their uncertainty 
and variability.
    The computer model DOE uses to calculate the LCC relies on a Monte 
Carlo simulation to incorporate uncertainty and variability into the 
analysis. The Monte Carlo simulations randomly sample input values from 
the probability distributions and refrigerator, refrigerator-freezer, 
and freezer user samples. For this rulemaking, the Monte Carlo approach 
is implemented in Python. The model calculated the LCC for products at 
each efficiency level for 10,000 housing units or commercial buildings 
per simulation run. The analytical results include a distribution of 
10,000 data points showing the range of LCC savings for a given 
efficiency level relative to the no-new-standards case efficiency 
distribution. In performing an iteration of the Monte Carlo simulation 
for a given consumer, product efficiency is chosen based on its 
probability. If the chosen product efficiency is greater than or equal 
to the efficiency of the standard level under consideration, the LCC 
calculation reveals that a consumer is not impacted by the standard 
level. By accounting for consumers who already purchase more efficient 
products, DOE avoids overstating the potential benefits from increasing 
product efficiency. DOE calculated the LCC and PBP for consumers of 
refrigerators, refrigerator-freezers, and freezers as if each were to 
purchase a new product in the first year of required compliance with 
new or amended standards. For all TSLs other than TSL 4 (the 
Recommended TSL detailed in the Joint Agreement), any amended standards 
were assumed to apply to refrigerators, refrigerator-freezers, and 
freezers manufactured 3 years after the date on which any new or 
amended standard is published. (42 U.S.C. 6295(m)(4)(A)(i)) Therefore, 
DOE used 2027 as the first year of compliance with any amended 
standards for refrigerators, refrigerator-freezers, and freezers for 
all TSLs other than TSL 4. For TSL 4, DOE used 2029 as the first year 
of compliance for representative PCs 5BI, 5A, 10, 11A, 17, and 18 and 
2030 as the first year of compliance for the representative PCs 3, 5, 
7, and 9, consistent with the Joint Agreement.
    Table IV.9 summarizes the approach and data DOE used to derive 
inputs to the LCC and PBP calculations. The subsections that follow 
provide further discussion. Details of the spreadsheet model, and of 
all the inputs to the LCC and PBP analyses, are contained in chapter 8

    In response to the February 2023 NOPR, an individual objected to 
the LCC analysis for two reasons: (1) future dollars savings are not 
the same as present-day dollars for purchase, which is especially 
problematic for low-income individuals; and (2) some in the elderly 
population would not live long enough to recover the incremental 
installed cost due to an amended standard, resulting in ``age 
discrimination.'' (Individual

[[Page 3056]]

Commenter, No. 59 at p. 2) In regard to future dollar savings vs. 
present-day dollar savings for low-income households, DOE's low-income 
consumer subgroup LCC analysis uses discount rates that are specific to 
low-income households, resulting in higher discount rates for these 
households, on average, compared to the full consumer sample used in 
the standard LCC analysis. See section IV.I of this document as well as 
chapter 11 of the direct final rule TSD for more details. In regard to 
the incremental installed cost for low-income consumers, DOE notes that 
many low-income consumers are renters who are typically not responsible 
for purchasing refrigeration equipment (see the discussion in section 
IV.I of this document as well as chapter 11 of the direct final rule 
TSD). Moreover, the low-income subgroup results indicate that low-
income households, on average, are expected to experience higher LCC 
savings and lower payback periods than the general population (see the 
results in section V.B.1.b of this document). In regard to some 
individuals not living long enough to recoup the incremental installed 
cost due to an amended standard, DOE notes that even in such cases--
which could happen to non-elderly consumers as well--the equipment 
would continue to reap energy savings, but for a new owner. Therefore, 
DOE does not believe the LCC analysis discriminates against elderly 
consumers relative to younger consumers in the general population.
    AHAM commented that due to the skewed nature of the LCC savings 
results, DOE should report median values rather than mean values. 
(AHAM, No. 69 at p. 18) DOE notes that there are a variety of ways to 
characterize distributions of impacts, and DOE considers the impacts of 
a potential amended standard on refrigerators, refrigerator-freezers, 
and freezers holistically. DOE also notes that the median LCC savings 
for affected consumers are shown in the box-and-whisker plots in 
chapter 8 of the direct final rule TSD.
    AHAM also commented that DOE should be conducting a purchase 
decision analysis in its LCC model to reflect the actual conditions and 
expectations of the purchaser. (AHAM, No. 69 at p. 15) In the current 
setup of LCC analysis, DOE is not explicitly modeling the purchase 
decision made by purchasers when the standard becomes effective. DOE's 
analysis is intended to model the range of individual outcomes likely 
to result from a hypothetical amended energy conservation standard at 
various levels of efficiency. DOE does not discount the consumer 
decision theory established in the broad behavioral economics field, 
but rather, notes that its methodological decision was made after 
considering the existence of various systematic market failures and 
their implication in rational versus actual purchase behavior. 
Furthermore, the outcome of the LCC is not considered in isolation, but 
in the context of the broader set of analyses, including the NIA. 
Moreover, the type of data required to facilitate a robust consumer 
choice modeling of a specific household appliance at the individual 
household level is currently lacking and AHAM did not provide much 
data. DOE further notes, that AHAM is a party to the Joint Agreement 
and is supportive of the recommended standard adopted in this direct 
final rule.
1. Adjusted Volume Distribution
    DOE developed adjusted volume distributions within each PC 
containing more than one representative unit to determine the 
likelihood that a given purchaser would select each of the 
representative units for a given PC from the engineering analysis. DOE 
estimated the distribution of adjusted volumes for PC 3 and PC 5 based 
on the capacity distribution reported in the TraQline[supreg] 
refrigerator data spanning from Q1 2018 to Q1 2019.\44\ DOE estimated 
the distribution of adjusted volumes for PC 11A based on the 
distribution of models from DOE's Compliance Certification Management 
System (``CCMS'') Database. Table IV.10 presents the adjusted volume 
distribution of each of the PCs having more than one representative 
unit. DOE assumed that the adjusted volume distribution remains 
constant over the years considered in the analysis.

2. Product Cost
    To calculate consumer product costs, DOE multiplied the MPCs 
developed in the engineering analysis by the markups described 
previously (along with sales taxes). DOE used different markups for 
baseline products and higher-efficiency products, because DOE applies 
an incremental markup to the increase in MSP associated with higher-
efficiency products.
    Economic literature and historical data suggest that the real costs 
of many products may trend downward over time according to ``learning'' 
or ``experience'' curves. Experience curve analysis implicitly includes 
factors such as efficiencies in labor, capital investment, automation, 
materials prices, distribution, and economies of scale at an industry-
wide level.\45\ In the experience curve method, the real cost of 
production is related to the cumulative production or ``experience'' 
with a manufactured product. DOE used historical Producer Price Index 
(``PPI'') data for ``household refrigerator and home freezer 
manufacturing'' from the Bureau of Labor Statistics' (``BLS'') spanning 
the time period between 1981 and 2022 as a proxy of the production cost 
for refrigerators, refrigerator-freezers and freezers.\46\ This is the 
most representative and current price index for refrigerators, 
refrigerator-freezers, and freezers. An inflation-adjusted price index 
was calculated by dividing the PPI series by the gross domestic product 
index from the Bureau of Economic Analysis for the same years. The 
cumulative production of refrigerators, refrigerator-freezers, and 
freezers were assembled from the annual shipments from the Association 
of Household Appliance Manufacturers (AHAM) between 1951 and 2022, and 
shipment estimates prior to 1951 using a trend analysis. The estimated 
learning rate (defined as the fractional reduction in price expected 
from each doubling of cumulative production) is 39.4 <plus-minus>1.9 
percent

    DOE included variable-speed compressors as a technology option for 
higher efficiency levels. To develop future prices specific for that 
technology, DOE applied a separate price trend to the controls portion 
of the variable-speed compressor, which represents part of the price 
increment when moving from an efficiency level achieved with the 
highest efficiency single-speed compressor to an efficiency

[[Page 3057]]

level with variable-speed compressor. DOE used PPI data on 
``semiconductors and related device manufacturing'' between 1967 and 
2022 to estimate the historic price trend of electronic components in 
the control.\47\ The regression, performed as an exponential trend line 
fit, results in an R-square of 0.99, with an annual price decline rate 
of 6.3 percent. See chapter 8 of the TSD for further details on this 
topic.

    In response to the February 2023 NOPR, AHAM commented that there is 
no theoretical underpinning for the implementation of an experience or 
learning curve and the functional form it should take. In addition, 
AHAM stated that the data that DOE used merely represents an empirical 
relationship, and a clear connection between the actual products in 
question and the data used needs to be made. AHAM noted that there is 
little reason to support the concept that price learning through 
manufacturing efficiencies should extend beyond the labor and materials 
in the product itself, and that such a relationship should not hold for 
other cost components. (AHAM, No. 69 at pp. 16-17)
    DOE notes that there is considerable empirical evidence of 
consistent price declines for appliances in the past few decades. 
Several studies examined refrigerator retail prices during different 
periods of time and showed that prices had been steadily falling while 
efficiency had been increasing, for example Dale, et al. (2009) \48\ 
and Taylor, et al. (2015).\49\ As mentioned in Taylor and Fujita 
(2013),\50\ Federal agencies have adopted different approaches to 
account for ``the changing future compliance costs that might result 
from technological innovation or anticipated behavioral changes.'' 
Given the limited data availability on historical manufacturing costs 
broken by different components, DOE utilized the Producer Price Index 
(``PPI'') published by the BLS as a proxy for manufacturing costs to 
represent the analyzed product as a whole. While products may 
experience varying degrees of price learning during different product 
stages, DOE modeled the average learning rate based on the full 
historical PPI series for ``household refrigerator and home freezer 
manufacturing'' to capture the overall price evolution in relation to 
the cumulative shipments. DOE also conducted sensitivity analyses that 
are based on a particular segment of the PPI data for household 
refrigerator manufacturing to investigate the impact of alternative 
product price projections (low price learning and high price learning) 
in the NIA of this direct final rule. DOE further notes, that AHAM is a 
party to the Joint Agreement and is supportive of the recommended 
standard adopted in this direct final rule.

---------------------------------------------------------------------------

3. Installation Cost
    Installation cost includes labor, overhead, and any miscellaneous 
materials and parts needed to install the product. DOE found no 
evidence that installation costs for refrigerators, refrigerator-
freezers, and freezers would be impacted with increased efficiency 
levels. As a result, DOE did not include installation costs in the LCC 
and PBP analysis.
4. Annual Energy Consumption
    For each sampled household or commercial building, DOE determined 
the energy consumption for a refrigerator, refrigerator-freezer, or 
freezer at different efficiency levels using the approach described 
previously in section IV.E of this document.
5. Energy Prices
    Because marginal electricity price more accurately captures the 
incremental savings associated with a change in energy use from higher 
efficiency, it provides a better representation of incremental change 
in consumer costs than average electricity prices. Therefore, DOE 
applied average electricity prices for the energy use of the product 
purchased in the no-new-standards case, and marginal electricity prices 
for the incremental change in energy use associated with the other 
efficiency levels considered.
    DOE derived electricity prices in 2022 using data from EEI Typical 
Bills and Average Rates reports. Based upon comprehensive, industry-
wide surveys, this semi-annual report presents typical monthly electric 
bills and average kilowatt-hour costs to the customer as charged by 
investor-owned utilities. For the residential sector, DOE calculated 
electricity prices using the methodology described in Coughlin and 
Beraki (2018).\51\ For the commercial sector, DOE calculated 
electricity prices using the methodology described in Coughlin and 
Beraki (2019).\52\

6. Maintenance and Repair Costs
    Repair costs are associated with repairing or replacing product 
components that have failed in an appliance; maintenance costs are 
associated with maintaining the operation of the product. Typically, 
small incremental increases in product efficiency entail no, or only 
minor, changes in repair and maintenance costs compared to baseline 
efficiency products. DOE is not aware of any data that suggest the cost 
of maintenance changes as a function of efficiency for refrigerators, 
refrigerator-freezers, and freezers. DOE therefore assumed that 
maintenance costs are the same regardless of EL and do not impact the 
LCC or PBP.
    For the February 2023 NOPR as well as this direct final rule, DOE 
developed a repair cost estimation method based on the average total 
installed cost and average annual repair costs by PC and EL from the 
September 2011 Final Rule. For each of three categories--standard-size 
refrigerator-freezers, standard-size freezers, and compact 
refrigeration products--DOE averaged the annual repair cost as a 
fraction of the total installed cost at each EL. Based on this method, 
DOE estimated consumers with standard-size refrigerator-freezers have 
annual repair costs equal to 1.8 percent of their total installed cost, 
consumers

[[Page 3058]]

with standard-size freezers have an annual repair cost of 0.8 percent 
of their total installed cost, and consumers with compact refrigeration 
products have an annual repair cost of 0.9 percent of their total 
installed cost. Because high-efficiency products have a higher 
installed cost, their estimated average annual repair costs are also 
higher.
    In response to the February 2023 NOPR, an individual commented that 
product reliability is inversely related to the number of product 
parts, and Strauch suggested that DOE use the MIL-HDBK-217 or the 
Bellcore/Telcordia reliability guides to inform its maintenance and 
repair cost analysis. (Individual Commenter, No. 59 at pp. 1-2) DOE 
appreciates the recommendation, but notes that the data required to 
properly use the MIL-HDBK-217 or Bellcore/Telcordia standards \54\ 
(e.g., parts count, parts stress conditions, and laboratory and field 
failure rates of specific parts) is unavailable in the LCC analysis. 
This is due to the fact that the LCC analyzes refrigerator, 
refrigerator-freezer, and freezer representative units as opposed to 
specific product models. Moreover, according to Hottinger Br[uuml]el & 
Kj[aelig]r (``HBK'') there are a number of limitations to such 
empirical methods, including: (1) the data used to inform these 
traditional empirical models is typically outdated, (2) whereas the 
models assume components fail independently of each other, in some 
cases the overall system design is the causal factor, and (3) obtaining 
high-quality field and manufacturing data to inform the adjustment 
factors used in the models is difficult.\55\ For these reasons, for 
this direct final rule analysis DOE continued to use the method used in 
the February 2023 NOPR.

---------------------------------------------------------------------------

    AHAM also commented that failed VIPs are unrepairable in the field 
meaning manufacturers work to ensure VIPs will not fail prior to the 
end of the product's useful life. (AHAM, No. 69 at p. 6) DOE 
appreciates this information but notes that, due to a lack of available 
data, the repair cost estimates used in the LCC analysis are not 
component-specific.
7. Product Lifetime
    DOE performed separate modeling of lifetime for standard-size 
refrigerators and refrigerator-freezers, standard-size freezers, and 
compact refrigeration products. For standard-size refrigerators, 
refrigerator-freezers, and freezers, DOE estimated product lifetimes by 
fitting a survival probability function to data on historical shipments 
and the age distributions of installed stock from RECS 2005, RECS 2009, 
RECS 2015, and RECS 2020. The survival function, which DOE assumed has 
the form of a cumulative Weibull distribution, provides an average and 
median lifetime. Moreover, the conversion from primary-to-secondary 
refrigerator or refrigerator-freezer was also modeled as part of the 
lifetime determination for standard-size refrigerators and 
refrigerator-freezers.
    For compact refrigerators, DOE estimated an average lifetime of 8.8 
years using data on shipments and the number of units in use (stock). 
For compact freezers, DOE did not have reliable stock data available to 
compare against historical shipments. Therefore, DOE estimated an 
average lifetime of 11.3 years by multiplying the average lifetime of 
compact refrigerators by the ratio of the average lifetime of standard-
size freezers (18.4 years) to the average lifetime of standard-size 
refrigerators and refrigerator-freezers (14.3 years).
    In response to the February 2023 NOPR, an individual commented that 
more stringent efficiency standards reduce the service lifetime of 
refrigerators, refrigerator-freezers, and freezers. (Individual 
Commenter, No. 59 at p. 1) DOE used the latest available data to inform 
the lifetime distributions used in this direct final rule analysis, and 
DOE does not have data to corroborate a causal connection between the 
stringency of efficiency standards and the expected service lifetime of 
refrigerators, refrigerator-freezers, and freezers. Therefore, DOE 
continues to assume that amending the efficiency standards for 
refrigerators, refrigerator-freezers, and freezers will not directly 
impact the estimated service lifetime of these products.
8. Discount Rates
    In the calculation of LCC, DOE applies discount rates appropriate 
to residential and commercial consumers to estimate the present value 
of future operating cost savings. DOE estimated distributions of 
residential and commercial discount rates for refrigerators, 
refrigerator-freezers, and freezers based on consumer financing costs 
and the opportunity cost of consumer funds (for the residential sector) 
and cost of capital of publicly traded firms (for the commercial 
sector).
    DOE applies weighted average discount rates calculated from 
consumer debt and asset data, rather than marginal or implicit discount 
rates.\56\ The LCC analysis estimates net present value over the 
lifetime of the product, so the appropriate discount rate will reflect 
the general opportunity cost of household funds, taking this time scale 
into account. Given the long time horizon modeled in the LCC, the 
application of a marginal interest rate associated with an initial 
source of funds is inaccurate. Regardless of the method of purchase, 
consumers are expected to continue to rebalance their debt and asset 
holdings over the LCC analysis period, based on the restrictions 
consumers face in their debt payment requirements and the relative size 
of the interest rates available on debts and assets. DOE estimates the 
aggregate impact of this rebalancing using the historical distribution 
of debts and assets.
---------------------------------------------------------------------------

    \56\ The implicit discount rate is inferred from a consumer 
purchase decision between two otherwise identical goods with 
different first cost and operating cost. It is the interest rate 
that equates the increment of first cost to the difference in net 
present value of lifetime operating cost, incorporating the 
influence of several factors: transaction costs; risk premiums and 
response to uncertainty; time preferences; interest rates at which a 
consumer is able to borrow or lend. The implicit discount rate is 
not appropriate for the LCC analysis because it reflects a range of 
factors that influence consumer purchase decisions, rather than the 
opportunity cost of the funds that are used in purchases.
---------------------------------------------------------------------------

    To establish residential discount rates for the LCC analysis, DOE 
identified all relevant household debt or asset classes in order to 
approximate a consumer's opportunity cost of funds related to appliance 
energy cost savings. It estimated the average percentage shares of the 
various types of debt and equity by household income group using data 
from the Federal Reserve Board's triennial Survey of Consumer Finances 
\57\ (``SCF'') starting in 1995 and ending in 2019. Using the SCF and 
other sources, DOE developed a distribution of rates for each type of 
debt and asset by income group to represent the rates that may apply in 
the year in which amended standards would take effect. DOE assigned 
each sample household a specific discount rate drawn from one of the 
distributions. The average rate across all types of household debt and 
equity and income groups, weighted by the shares of each type, is

[[Page 3059]]

approximately 4 percent (the average varies by PC).

---------------------------------------------------------------------------

    For commercial consumers, DOE used the cost of capital to estimate 
the present value of cash flows to be derived from a typical company 
project or investment. Most companies use both debt and equity capital 
to fund investments, so the cost of capital is the weighted-average 
cost to the firm of equity and debt financing. This corporate finance 
approach is referred to as the weighted-average cost of capital. DOE 
used currently available economic data in developing discount rates. 
The average discount rate for the PC 11A commercial consumer sample is 
6.8 percent.
    In response to the February 2023 NOPR, AHAM commented that 
operating costs and the depreciation of capital investments are 
deductible costs for commercial end-users from Federal and State 
corporate income taxes. AHAM suggested that DOE should incorporate the 
effects of tax deductibility in the LCC analysis. (AHAM, No. 69 at p. 
19) DOE responds that as noted in the comment, the estimation of 
commercial discount rates accounts for the tax deductibility of the 
energy costs and capital investment depreciation and therefore the net 
present value of the future operating cost savings in the LCC analysis 
should already reflect that effect.
    In response to the February 2023 NOPR, AHAM further commented that 
DOE used an inappropriate discount rate in its analysis of the effects 
of standards on low-income households, claiming that it does not take 
into account issues of capital availability or the non-financial costs 
from a purchase. AHAM also presented data from their survey work with 
Bellomy Research showing that the lowest 30 percent income groups have 
no discretionary income to save, making it impossible for them to 
rebalance their balance sheets after making a purchase. (AHAM, No. 69 
at p. 11)
    With respect to the issue of DOE's methodology for estimating 
consumer discount rates, DOE maintains that the LCC is not predicting a 
purchase decision, which DOE assumes to be AHAM's interpretation given 
their focus on the availability of cash for appliance purchases. 
Rather, the LCC estimates the net present value of the financial impact 
of a given standard level over the lifetime of the product (i.e., 30 
years) assuming the standard-compliant product has already been 
installed and allows for comparison of this value across different 
hypothetical minimum efficiency levels. It is applied to future-year 
energy costs and non-energy operations and maintenance costs in order 
to calculate the net present value of the appliance to a household at 
the time of installation. The consumer discount rate reflects the 
opportunity cost of receiving energy cost savings in the future, rather 
than at the time of purchase and installation. The opportunity cost of 
receiving operating cost savings in future years, rather than in the 
first year of the modeled period, is dependent on the rate of return 
that could be earned if invested into an interest-bearing asset or the 
interest cost accrual avoided by paying down debt. Consumers in all 
income bins generally hold a variety of assets (e.g., certificates of 
deposit, stocks, bonds) and debts (e.g., mortgage, credit cards, 
vehicle loan), which vary in amount over time as consumers allocate 
their earnings, make new investments, etc. Thus, the consumer discount 
rate is estimated as a weighted average of the rates and proportions of 
the various types of assets and debts held by households in a given 
income bin, as reported by the Survey of Consumer Finances. In the low-
income subgroup analysis, DOE specifically evaluated the impacts of 
increased efficiency on low-income households using discount rates 
estimated specifically for the low-income bin. DOE further notes, that 
AHAM is a party to the Joint Agreement and is supportive of the 
recommended standard adopted in this direct final rule.
    See chapter 8 of the direct final rule TSD for further details on 
the development of consumer discount rates.
9. Energy Efficiency Distribution in the No-New-Standards Case
    To accurately estimate the share of consumers that would be 
affected by a potential energy conservation standard at a particular 
efficiency level, DOE's LCC analysis considered the projected 
distribution (market shares) of product efficiencies under the no-new-
standards case (i.e., the case without amended or new energy 
conservation standards).
    To estimate the energy efficiency distribution of refrigerators, 
refrigerator-freezers, and freezers, DOE used current shipments data 
provided by AHAM in response to the NOPR for PCs 3, 5, 5A, 7, 9, 11A, 
and 18, and model counts from DOE's CCMS database for PCs 5BI, 10, and 
17. (AHAM, No. 69 at pp. 2-3) Models in the database were categorized 
by capacity and assigned an efficiency level based on reported energy 
use. In the absence of data on trends in efficiency, DOE assumed the 
current efficiency distribution would be representative of the 
efficiency distribution in the compliance year in the no-new-standards 
case. The estimated market shares for the no-new-standards case for 
refrigerators, refrigerator-freezers, and freezers are shown in Table 
IV.11. See chapter 8 of the direct final rule TSD for further 
information on the derivation of the efficiency distributions.

    The LCC Monte Carlo simulations draw from the efficiency 
distributions and randomly assign an efficiency to the refrigerator, 
refrigerator-freezer, or freezer purchased by each sample household in 
the no-new-standards case. The resulting percent shares within the 
sample match the market shares in the efficiency distributions.
    In the February 2023 NOPR, DOE performed a random assignment of 
efficiency levels to consumers in its Monte Carlo sample. 88 FR 12452, 
12484-12485. While DOE acknowledges that economic factors may play a 
role when consumers decide on what type of refrigerator, refrigerator-
freezer, or freezer to install, assignment of refrigeration product 
efficiency for a given installation, based solely on economic measures 
such as life-cycle cost or simple payback period, most likely would not 
fully and accurately reflect actual real-world installations. There are 
a number of market failures discussed in the economics literature that 
illustrate how purchasing decisions with respect to energy efficiency 
are unlikely to be perfectly correlated with energy use, as described 
below. DOE maintains that the method of assignment, which is in part 
random, is a reasonable approach, because it simulates behavior in the 
refrigeration product market, where market failures result in 
purchasing decisions not being perfectly aligned with economic 
interests, and is more realistic than relying only on apparent cost-
effectiveness criteria derived from the limited information in RECS. 
DOE further emphasizes that its approach does not assume that all 
purchasers of refrigeration products make economically irrational 
decisions (i.e., the lack of a correlation is not the same as a 
negative correlation). By using this approach, DOE acknowledges the 
uncertainty inherent in the data and minimizes any bias in the analysis 
by using random assignment, as opposed to assuming certain market 
conditions that are unsupported given the available evidence.
    The following discussion provides more detail about the various 
market failures that affect refrigeration product purchases. First, 
consumers are motivated by more than simple financial trade-offs. There 
are consumers who are willing to pay a premium for more energy-
efficient products because they are environmentally conscious.\58\ 
There are also several behavioral factors that can influence the 
purchasing decisions of complicated multi-attribute products, such as 
refrigeration products. For example, consumers (or decision makers in 
an organization) are highly influenced by choice architecture, defined 
as the framing of the decision, the surrounding circumstances of the 
purchase, the alternatives available, and how they are presented for 
any given choice scenario.\59\ The same consumer or decision maker may 
make different choices depending on the characteristics of the decision 
context (e.g., the timing of the purchase, competing demands for 
funds), which have nothing to do with the characteristics of the 
alternatives themselves or their prices. Consumers or decision makers 
also face a variety of other behavioral phenomena including loss 
aversion, sensitivity to information salience, and other forms of 
bounded rationality.\60\ Thaler, who won the Nobel Prize in Economics 
in 2017 for his contributions to behavioral economics, and Sunstein 
point out that these behavioral factors are strongest when the 
decisions are complex and infrequent, when feedback on the decision is 
muted and slow, and when there is a high degree of information 
asymmetry.\61\ These characteristics describe almost all purchasing 
situations of appliances and equipment, including refrigerators, 
refrigerator-freezers, and freezers. The installation of a new or 
replacement refrigeration products is done very infrequently, as 
evidenced by the mean lifetime of 14.3 years for standard-size 
refrigerators and refrigerator-freezers and 18.4 years for standard-
size freezers. Further, if the purchaser of the refrigerator, 
refrigerator-freezer, or freezer is not the entity paying the energy 
costs (e.g., a building owner and tenant), there may be little to no 
feedback on the purchase. Additionally, there are systematic market 
failures that are likely to contribute further complexity to how 
products are chosen by consumers, as explained in the following 
paragraphs. The first of these market failures--the split-incentive or 
principal-agent problem--is likely to significantly affect 
refrigerators, refrigerator-freezers, and freezers. The principal-agent 
problem is a market failure that results when the consumer that 
purchases the equipment does not internalize all of the costs 
associated with operating the equipment. Instead, the user of the 
product, who has no control over the purchase decision, pays the 
operating costs. There is a high likelihood of split-incentive problems 
in the case of rental properties where the landlord makes the choice of 
what refrigeration product to install, whereas the renter is 
responsible for paying energy bills.

---------------------------------------------------------------------------

    In addition to the split-incentive problem, there are other market 
failures that are likely to affect the choice of refrigerator, 
refrigerator-freezer, or freezer product efficiency made by consumers. 
For example, unplanned replacements due to unexpected failure of 
equipment such as refrigeration products are strongly biased toward 
like-for-like replacement (i.e., replacing the non-functioning 
equipment with a similar or identical product). Time is a constraining 
factor during unplanned replacements, and consumers may not consider 
the full range of available options on the market, despite their 
availability. The consideration of alternative product options is far 
more likely for planned replacements and installations in new 
construction.
    Additionally, Davis and Metcalf \62\ conducted an experiment 
demonstrating that, even when consumers are presented with energy 
consumption information, the nature of the information available to 
consumers (e.g., from EnergyGuide labels) results in an inefficient 
allocation of energy efficiency across households with different usage 
levels. Their findings indicate that households are likely to make 
decisions regarding the efficiency of the air conditioning equipment of 
their homes that do not result in the highest net present value for 
their specific usage pattern (i.e., their decision is based on 
imperfect information and, therefore, is not necessarily optimal). 
Also, most consumers did not properly understand the labels 
(specifically whether energy consumption and cost estimates were 
national averages or specific to their

[[Page 3061]]

State). As such, consumers did not make the most informed decisions.

---------------------------------------------------------------------------

    In part because of the way information is presented, and in part 
because of the way consumers process information, there is also a 
market failure consisting of a systematic bias in the perception of 
equipment energy usage, which can affect consumer choices. Attari et 
al.\63\ show that consumers tend to underestimate the energy use of 
large energy-intensive appliances (such as air conditioners, 
dishwashers, and clothes dryers), but overestimate the energy use of 
small appliances (such as light bulbs). Therefore, it is possible that 
consumers systematically underestimate the energy use associated with 
refrigerators, refrigerator-freezers, and freezers, resulting in less 
cost-effective purchases.

---------------------------------------------------------------------------

    These market failures affect a sizeable share of the consumer 
population. A study by Houde \64\ indicates that there is a significant 
subset of consumers that appear to purchase appliances without taking 
into account their energy efficiency and operating costs at all.

---------------------------------------------------------------------------

    The existence of market failures in the residential sector is well 
supported by the economics literature and by a number of case studies. 
If DOE developed an efficiency distribution that assigned refrigeration 
product efficiency in the no-new-standards case solely according to 
energy use or economic considerations such as life-cycle cost or 
payback period, the resulting distribution of efficiencies within the 
consumer sample would not reflect any of the market failures or 
behavioral factors above. Thus, DOE concludes such a distribution would 
not be representative of the refrigeration product market. Further, 
even if a specific household is not subject to the market failures 
above, the purchasing decision of refrigerator, refrigerator-freezer, 
or freezer product efficiency can be highly complex and influenced by a 
number of factors (e.g., aesthetics) not captured by the building 
characteristics available in the RECS sample. These factors can lead to 
households or building owners choosing a refrigeration product 
efficiency that deviates from the efficiency predicted using only 
energy use or economic considerations such as life-cycle cost or 
payback period.
    There is a complex set of behavioral factors, with sometimes 
opposing effects, affecting the refrigeration product market. It is 
impractical to model every consumer decision incorporating all of these 
effects at this extreme level of granularity given the limited 
available data. Given these myriad factors, DOE estimates the resulting 
distribution of such a model, if it were possible, would be very 
scattered with high variability. It is for this reason DOE utilizes a 
random distribution (after accounting for efficiency market share 
constraints) to approximate these effects. The methodology is not an 
assertion of economic irrationality, but instead, it is a 
methodological approximation of complex consumer behavior. The analysis 
is neither biased toward high or low energy savings. The methodology 
does not preferentially assign lower-efficiency refrigeration products 
to households in the no-new-standards case where savings from the rule 
would be greatest, nor does it preferentially assign lower-efficiency 
refrigeration products to households in the no-new-standards case where 
savings from the rule would be smallest. Some consumers were assigned 
the refrigeration products that they would have chosen if they had 
engaged in perfect economic considerations when purchasing the 
products. Others were assigned less-efficient refrigeration products 
even where a more-efficient product would eventually result in life-
cycle savings, simulating scenarios where, for example, various market 
failures prevent consumers from realizing those savings. Still others 
were assigned refrigeration products that were more efficient than one 
would expect simply from life-cycle costs analysis, reflecting, say, 
``green'' behavior, whereby consumers ascribe independent value to 
minimizing harm to the environment.
10. Payback Period Analysis
    The payback period is the amount of time (expressed in years) it 
takes the consumer to recover the additional installed cost of more 
efficient products, compared to baseline products, through energy cost 
savings. Payback periods that exceed the life of the product mean that 
the increased total installed cost is not recovered in reduced 
operating expenses.
    The inputs to the PBP calculation for each efficiency level are the 
change in total installed cost of the product and the change in the 
first-year annual operating expenditures relative to the baseline. DOE 
refers to this as a ``simple PBP'' because it does not consider changes 
over time in operating cost savings. The PBP calculation uses the same 
inputs as the LCC analysis when deriving first-year operating costs.
    As noted previously, EPCA establishes a rebuttable presumption that 
a standard is economically justified if the Secretary finds that the 
additional cost to the consumer of purchasing a product complying with 
an energy conservation standard level will be less than three times the 
value of the first year's energy savings resulting from the standard, 
as calculated under the applicable test procedure. (42 U.S.C. 
6295(o)(2)(B)(iii)) For each considered efficiency level, DOE 
determined the value of the first year's energy savings by calculating 
the energy savings in accordance with the applicable DOE test 
procedure, and multiplying those savings by the average energy price 
projection for the year in which compliance with the amended standards 
would be required.

G. Shipments Analysis

    DOE uses projections of annual product shipments to calculate the 
national impacts of potential amended or new energy conservation 
standards on energy use, NPV, and future manufacturer cash flows.\65\ 
The shipments model takes an accounting approach, tracking market 
shares of each product class and the vintage of units in the stock. 
Stock accounting uses product shipments as inputs to estimate the age 
distribution of in-service product stocks for all years. The age 
distribution of in-service product stocks is a key input to 
calculations of both the NES and NPV, because operating costs for any 
year depend on the age distribution of the stock. For this direct final 
rule, DOE excluded PC 9A--BI from the shipments analysis due to its 
very small shipments volume.
---------------------------------------------------------------------------

    \65\ DOE uses data on manufacturer shipments as a proxy for 
national sales, as aggregate data on sales are lacking. In general, 
one would expect a close correspondence between shipments and sales.
---------------------------------------------------------------------------

    Total shipments for each product category (i.e., standard-size 
refrigerators and refrigerator-freezers, standard-size freezers, 
compact refrigerators and refrigerator-freezers, and compact freezers) 
are developed by considering the demand from various market segments. 
For standard-size refrigerators and refrigerator-freezers, DOE 
considered demand from replacements for units in stock that fail, 
shipments to new construction, and the demand created by increased 
saturation into existing households corresponding to

[[Page 3062]]

the conversion of a primary unit to secondary unit. For all other 
product categories, DOE considered demand from replacements for units 
in stock that fail, shipments to new construction, and shipments to 
first-time owners in existing households. DOE calculated shipments due 
to replacements using the retirement functions developed for the LCC 
analysis (see chapter 8 of the direct final rule TSD for details). DOE 
projected shipments to new construction using estimates for new housing 
starts and the average saturation of each product category in new 
households. Shipments to first-time owners were estimated by analyzing 
the increasing penetration of products into existing households in each 
product category. For standard-size refrigerators and refrigerator-
freezers, DOE estimated shipments from increased saturation 
corresponding to the conversion of a primary unit to a secondary unit 
utilizing the primary-to-secondary conversion function developed for 
the LCC analysis. More detail on this methodology can be found in 
chapter 8 of the direct final rule TSD.
    For the direct final rule analysis, DOE incorporated data from 
stakeholders into the shipments. Confidential aggregate historical 
shipments data from 2015-2022 provided by AHAM were used to calibrate 
the total shipments for standard-size refrigerator-freezers, compact 
refrigerators, upright freezers, chest freezers, and built-in 
refrigerator-freezers. For the direct final rule, DOE used the AHAM-
provided estimates for the efficiency distributions based on shipments 
for standard-size refrigerator-freezers and compact freezers. (AHAM, 
No. 69 at pp. 2-3)
    Whirlpool requested that DOE provide data to indicate that there 
would be no impact to appliance replacement at the proposed standard 
level at TSL 5. (Whirlpool, No. 85 at pp. 8-9) DOE uses a price 
elasticity of demand to address the impact of increased prices on 
shipments based on an analysis using market-level appliance data 
including refrigerators.\66\ DOE provides the description of the price 
elasticity methodology in chapter 9 in the direct final rule TSD.

    Chapter 9 in the direct final rule TSD provides further information 
on the shipments analysis.

H. National Impact Analysis

    The NIA assesses the national energy savings (``NES'') and the NPV 
from a national perspective of total consumer costs and savings that 
would be expected to result from new or amended standards at specific 
efficiency levels.\67\ (``Consumer'' in this context refers to 
consumers of the product being regulated.) DOE calculates the NES and 
NPV for the potential standard levels considered based on projections 
of annual product shipments, along with the annual energy consumption 
and total installed cost data from the energy use and LCC analyses. For 
the present analysis, DOE projected the energy savings, operating cost 
savings, product costs, and NPV of consumer benefits over the lifetime 
of refrigerators, refrigerator-freezers, and freezers sold from 2027 
through 2056 for all TSLs other than TSL 4, the Recommended TSL 
detailed in the Joint Agreement. For TSL 4, DOE projected the energy 
savings, operating cost savings, product costs, and NPV of consumer 
benefits over the lifetime of refrigerators, refrigerator-freezers, and 
freezers sold from 2029 through 2058 for the product classes listed in 
Table I.1 and 2030 through 2059 for the product classes listed in Table 
I.2.
---------------------------------------------------------------------------

    \67\ The NIA accounts for impacts in the 50 states and U.S. 
territories.
---------------------------------------------------------------------------

    DOE evaluates the impacts of new or amended standards by comparing 
a case without such standards with standards-case projections. The no-
new-standards case characterizes energy use and consumer costs for each 
product class in the absence of new or amended energy conservation 
standards. For this projection, DOE considers historical trends in 
efficiency and various forces that are likely to affect the mix of 
efficiencies over time. DOE compares the no-new-standards case with 
projections characterizing the market for each product class if DOE 
adopted new or amended standards at specific energy efficiency levels 
(i.e., the TSLs or standards cases) for that class. For the standards 
cases, DOE considers how a given standard would likely affect the 
market shares of products with efficiencies greater than the standard.
    DOE uses a spreadsheet model, which is available in the docket, to 
calculate the energy savings and the national consumer costs and 
savings from each TSL. Interested parties can review DOE's analyses by 
changing various input quantities within the spreadsheet. The NIA 
spreadsheet model uses typical values (as opposed to probability 
distributions) as inputs.
    Table IV.12 summarizes the inputs and methods DOE used for the NIA 
analysis for the direct final rule. Discussion of these inputs and 
methods follows the table. See chapter 10 of the direct final rule TSD 
for further details.

1. Product Efficiency Trends
    A key component of the NIA is the trend in energy efficiency 
projected for the no-new-standards case and each of the standards 
cases. Section IV.F.9 of this document describes how DOE developed an 
energy efficiency distribution for the no-new-standards case (which 
yields a shipment-weighted average efficiency) for each of the 
considered product classes for the year of anticipated compliance with 
an amended or new standard.
    For the standards cases, DOE used a ``roll up'' scenario to 
establish the shipment-weighted efficiency for the year that standards 
are assumed to become effective. In this scenario, the market shares of 
products in the no-new-standards case that do not meet the standard 
under consideration would ``roll up'' to meet the new standard level, 
and the market share of products above the standard would remain 
unchanged. In the absence of data on trends in efficiency, DOE assumed 
no efficiency trend over the analysis period for both the no-new-
standards and standards cases. For a given case, market shares by 
efficiency level were held fixed to their distribution in the 
compliance year. The approach is further described in chapter 10 of the 
direct final rule TSD.
2. National Energy Savings
    The national energy savings analysis involves a comparison of 
national energy consumption of the considered products between each 
potential standards case (``TSL'') and the case with no new or amended 
energy conservation standards. DOE calculated the national energy 
consumption by multiplying the number of units (stock) of each product 
(by vintage or age) by the unit energy consumption (also by vintage). 
DOE calculated annual NES based on the difference in national energy 
consumption for the no-new-standards case and for each higher 
efficiency standard case. DOE estimated energy consumption and savings 
based on site energy and converted the electricity consumption and 
savings to primary energy (i.e., the energy consumed by power plants to 
generate site electricity) using annual conversion factors derived from 
AEO2023. Cumulative energy savings are the sum of the NES for each year 
over the timeframe of the analysis.
    In this direct final rule analysis, DOE analyzed the energy and 
economic impacts of a potential standard on all product classes in the 
scope of refrigerators, refrigerator-freezers, and freezers. Results 
for non-representative product classes (i.e., those not analyzed in the 
engineering, energy use, and LCC analyses) are scaled using results for 
the analyzed product class that best represents each non-representative 
product class. For non-representative freestanding product classes, 
energy use values are scaled by applying the ratio of the current 
Federal standard baseline between the two product classes at a fixed 
volume. For non-representative built-in product classes, DOE developed 
energy scalars using the most similar freestanding representative 
product class and assumed a 5-percent reduction in the increase in 
efficiency at each EL relative to the corresponding EL for the 
freestanding product class. For example, a 10-percent reduction in 
energy use for PC 3 would correspond to a 5-percent reduction for PC 3-
BI. DOE assumes the incremental cost between efficiency levels is the 
same for representative and non-representative product classes. See 
chapter 10 of the direct final rule TSD for more details.
    In this direct final rule, for the Recommended TSL (TSL 4), the 
scaling of certain non-representative product classes (specifically PC 
12, PC 4-BI, PC 7-BI, and PC 9-BI) has been modified from the February 
2023 NOPR, consistent with the Joint Agreement. In the February 2023 
NOPR, PC 12 was scaled to PC 11A with the same standard level for PC 12 
as PC 11A under a given TSL. However, under the Joint Agreement, at the 
Recommended TSL, PC 12 is scaled differently. At TSL 4, for PC 11A, the 
standard is met at EL 2 and for PC 12, the standard level corresponds 
to EL 1 for PC 11A. Thus, for TSL 4, DOE updated its scaling for PC 12 
to reflect EL 1 rather than EL 2 from PC 11A. In the February 2023 
NOPR, PC 4-BI and PC 7-BI were scaled to PC 7, and the standard level 
under TSL 4 corresponded to EL 3 for PC 4-BI, PC 7-BI, and PC 7. Under 
the Joint Agreement, at TSL 4, PC 7 continues to correspond to EL 3, 
but PC 4-BI and PC 7-BI correspond to EL 4. Finally, in the February 
2023 NOPR, PC 9--BI was scaled to PC 9, and both met the standard under 
TSL 4 at EL1. At TSL4, the standard for PC 9 is met at EL 2 while PC-9 
BI continues to be scaled to EL 1.
    Use of higher-efficiency products is sometimes associated with a 
direct rebound effect, which refers to an increase in utilization of 
the product due to the increase in efficiency. DOE did not find any 
data on the rebound effect specific to refrigerators that would 
indicate that consumers would alter their utilization of their product 
as a result of an increase in efficiency. DOE assumed a rebound rate of 
0. DOE did not receive any comments regarding this assumption in 
response to the February 2023 NOPR.
    In 2011, in response to the recommendations of a committee on 
``Point-of-Use and Full-Fuel-Cycle Measurement Approaches to Energy 
Efficiency Standards'' appointed by the National Academy of Sciences, 
DOE announced its intention to use FFC measures of energy use and 
greenhouse gas and other emissions in the national impact analyses and 
emissions analyses included in future energy conservation standards 
rulemakings. 76 FR 51281 (Aug. 18, 2011). After evaluating the 
approaches discussed in the August 18, 2011 statement of policy, DOE 
published a statement of amended policy in which DOE explained its 
determination that EIA's National Energy Modeling System (``NEMS'') is 
the most appropriate tool for its FFC analysis and its intention to use 
NEMS for that purpose. 77 FR 49701 (Aug. 17, 2012). NEMS is a public 
domain, multi-sector, partial equilibrium model of the U.S. energy 
sector \68\ that EIA uses to prepare its Annual Energy Outlook. The FFC 
factors incorporate losses in production and delivery in the case of 
natural gas (including fugitive emissions) and additional energy used 
to produce and deliver the various fuels used by power plants. The 
approach used for deriving FFC measures of energy use and emissions is 
described in appendix 10B of the direct final rule TSD.

3. Net Present Value Analysis
    The inputs for determining the NPV of the total costs and benefits 
experienced by consumers are (1) total annual installed cost, (2) total 
annual operating costs (energy costs and repair and maintenance costs), 
and (3) a discount factor to calculate the present value of costs and 
savings. DOE calculates net savings each year as the difference between 
the no-new-standards case and each standards case in terms of total 
savings in operating costs versus total increases in installed costs. 
DOE calculates operating cost savings over the lifetime of each product 
shipped during the projection period.
    As discussed in section IV.F.2 of this document, DOE developed 
refrigerators, refrigerator-freezers, and freezers price trends based 
on an experience curve calculated using historical PPI data. For 
efficiency levels with a single-speed compressor, DOE applied a price 
trend

[[Page 3064]]

developed using the ``household refrigerator and home freezer 
manufacturing'' PPI to the entire cost of the unit. For efficiency 
levels with a variable-speed compressor, DOE applied a price trend 
developed from the ``semiconductors and related device manufacturing'' 
PPI to the cost associated with the electronics used to control the 
variable-speed compressor and the same price trend used for single-
speed compressor units to the non-controls portion of the cost of the 
unit. By 2059, which is the end date of the projection period for the 
Recommended TSL detailed in the Joint Agreement, the average single-
speed compressor refrigerators, refrigerator-freezers, and freezers 
price is projected to drop 33-percent relative to 2030. DOE's 
projection of product prices is described in chapter 8 of the direct 
final rule TSD.
    To evaluate the effect of uncertainty regarding the price trend 
estimates, DOE investigated the impact of different product price 
projections on the consumer NPV for the considered TSLs for 
refrigerators, refrigerator-freezers, and freezers. In addition to the 
default price trend, DOE considered two product price sensitivity 
cases: For the single-speed compressor refrigerators, refrigerator-
freezers, and freezers and the non-variable-speed controls portion of 
refrigerators, refrigerator-freezers, and freezers, DOE estimated the 
high-price-decline and the low-price-decline scenarios based on 
household refrigerator and home freezer PPI data limited to the period 
between the period 1981-2008 and 2009-2021, respectively. For the 
variable-speed controls portion of refrigerators, refrigerator-
freezers, and freezers, DOE estimated the high-price-decline and the 
low-price-decline scenarios based on an exponential trend line fit of 
the semiconductor PPI between the period 1994-2021 and 1967-1993, 
respectively. The derivation of these price trends and the results of 
these sensitivity cases are described in appendix 10C of the direct 
final rule TSD.
    The energy cost savings are calculated using the estimated energy 
savings in each year and the projected price of the appropriate form of 
energy. To estimate energy prices in future years, DOE multiplied the 
average regional energy prices by the projection of annual national-
average residential energy price changes in the Reference case from 
AEO2023, which has an end year of 2050. To estimate price trends after 
2050, the 2046-2050 average was used for all years. As part of the NIA, 
DOE also analyzed scenarios that used inputs from variants of the 
AEO2023 Reference case that have lower and higher economic growth. 
Those cases have lower and higher energy price trends compared to the 
Reference case. NIA results based on these cases are presented in 
appendix 10C of the direct final rule TSD.
    In calculating the NPV, DOE multiplies the net savings in future 
years by a discount factor to determine their present value. For this 
direct final rule, DOE estimated the NPV of consumer benefits using 
both a 3-percent and a 7-percent real discount rate. DOE uses these 
discount rates in accordance with guidance provided by the Office of 
Management and Budget (``OMB'') to Federal agencies on the development 
of regulatory analysis.\69\ The discount rates for the determination of 
NPV are in contrast to the discount rates used in the LCC analysis, 
which are designed to reflect a consumer's perspective. The 7-percent 
real value is an estimate of the average before-tax rate of return to 
private capital in the U.S. economy. The 3-percent real value 
represents the ``social rate of time preference,'' which is the rate at 
which society discounts future consumption flows to their present 
value.

I. Consumer Subgroup Analysis

    In analyzing the potential impact of new or amended energy 
conservation standards on consumers, DOE evaluates the impact on 
identifiable subgroups of consumers that may be disproportionately 
affected by a new or amended national standard. The purpose of a 
subgroup analysis is to determine the extent of any such 
disproportional impacts. DOE evaluates impacts on particular subgroups 
of consumers by analyzing the LCC impacts and PBP for those particular 
consumers from alternative standard levels.
    For this direct final rule, DOE analyzed the impacts of the 
considered standard levels on low-income households and, for PC 11A, on 
small businesses. For low-income households, the analysis used a subset 
of the RECS 2020 sample composed of low-income households. DOE 
separately analyzed different groups in the low-income household sample 
using data from RECS on home ownership status and on who pays the 
electricity bill. Low-income homeowners are analyzed equivalently to 
how they are analyzed in the standard LCC analysis. Low-income renters 
who do not pay their electricity bill are assumed to not be impacted by 
any new or amended standards. In this case, the landlord purchases the 
appliance and pays its operating costs, so is effectively the consumer 
and the renter is not impacted. Low-income renters who do pay their 
electricity bill are assumed to incur no first cost. DOE made this 
assumption to acknowledge that the vast majority of low-income renters 
may not pay to have their refrigerator, refrigerator-freezer, or 
freezer replaced (that would be up to the landlord).
    DOE notes that RECS 2020 indicates that a small fraction of low-
income households only have a single compact refrigerator and/or 
freezer. Because this is the only refrigeration product in the 
household, DOE assumed that the landlord typically supplies the 
product. Additionally, RECS 2020 indicates that a small fraction of 
low-income households have a refrigeration product that would be 
categorized into PC 5, PC 5BI, or PC 5A. As a result, DOE did not do a 
low-income subgroup analysis on PCs 5, 5BI, 5A, 11A, 17, and 18.
    For small businesses, DOE used the same sample from CBECS 2018 that 
was used in the standard LCC analysis but used discount rates specific 
to small businesses. DOE used the LCC and PBP model to estimate the 
impacts of the considered efficiency levels on these subgroups.
    Chapter 11 in the direct final rule TSD describes the consumer 
subgroup analysis.
    In response to the February 2023 NOPR, AHAM commented that amended 
standards requiring more variable-speed compressors could lead to 
higher upfront costs, disproportionately impacting low-income 
consumers. (AHAM, No. 69 at p. 5) Whirlpool added that the proposed 
standards would raise the cost of entry-level models, which are the 
preferred models for low-income consumers. (Whirlpool, No. 70 at pp. 5-
6) As noted previously, many low-income consumers are renters who are 
not expected to pay the incremental cost due to an amended standard. 
For low-income homeowners who are expected to bear that incremental 
cost, the analysis incorporates the higher incremental costs at each 
considered TSL. DOE notes that at the Recommended TSL (TSL 4), the 
estimated increase in installed cost relative to the baseline (EL 0) 
product across PCs 3, 7, and 9 is less than $20. Moreover, in the 
aggregate, DOE finds that low-income consumers have higher average LCC 
savings and lower payback periods relative to the general population 
(see the results in section

[[Page 3065]]

V.B.1.b of this document). DOE also finds that, in the aggregate, only 
8.6 percent of impacted low-income consumers would experience a net 
cost at TSL 4, meaning 91.4 percent would see no change or a net 
benefit.
    AHAM also commented that DOE has not supported its split-incentive 
assumption for low-income renters (i.e., renters will reap benefits of 
more efficient products through lower utility bills while landlords 
have little to no incentive to purchase more efficient products) nor 
has DOE considered the impact of amended standards on low-income 
homeowners. (AHAM, No. 69 at p. 10) AHAM provided consumer research 
results indicating that cost is the primary consideration for 
households when purchasing a new refrigerator, low-income households 
that make less than $25,000 per year would not be able to purchase a 
new refrigerator, and 78 percent of such households would not pay $100 
extra for a more efficient refrigerator that saved $50-$150 in utility 
bills over 10 years. (AHAM, No. 69 at pp. 10-11) AHAM added that the 
proposed standards in the February 2023 NOPR will result in 
insignificant savings for consumers, which do not amount to a material 
benefit, especially for low-income consumers. (AHAM, No. 69 at p. 15) 
Whirlpool commented that DOE's assumption that landlords will absorb 
increased appliance costs and not pass them on to tenants is incorrect. 
(Whirlpool, No. 70 at p. 6)
    The existence of a split-incentive across a substantial number of 
U.S. households, in which a tenant pays for the cost of electricity 
while the building owner furnishes appliances, has been identified 
through a number of studies of residential appliance and equipment use 
broadly. Building from early work including Jaffe and Stavins,\70\ 
Murtishaw and Sathaye \71\ discussed the presence of landlord-tenant 
split incentives (i.e., the ``principal-agent problem''). While the 
study did not solely focus on the low-income households, they estimated 
that 33% of all residential refrigerator use is subject to the 
principal-agent problem, largely within rental housing. Spurlock and 
Fujita \72\ showed that 87% of low-income individuals who rented their 
homes were found to pay the electricity bill resulting from their 
energy use, such that they were likely subject to a scenario in which 
their landlord purchased the appliance, but they paid the operating 
costs. DOE notes that there continues to be a lack of data to 
corroborate the notion that landlords pass on some, or all, of 
increased appliance costs to tenants. Without representative data to 
suggest otherwise, DOE has continued to analyze low-income renters 
under the assumption that they pay no upfront costs under an amended 
standard in this direct final rule. DOE further notes, that AHAM is a 
party to the Joint Agreement and is supportive of the recommended 
standard adopted in this direct final rule.

J. Manufacturer Impact Analysis

1. Overview
    DOE performed an MIA to estimate the financial impacts of amended 
energy conservation standards on manufacturers of refrigerators, 
refrigerator-freezers, and freezers and to estimate the potential 
impacts of such standards on employment and manufacturing capacity. The 
MIA has both quantitative and qualitative aspects and includes analyses 
of projected industry cash flows, the INPV, investments in research and 
development (``R&D'') and manufacturing capital, and domestic 
manufacturing employment. Additionally, the MIA seeks to determine how 
amended energy conservation standards might affect manufacturing 
employment, capacity, and competition, as well as how standards 
contribute to overall regulatory burden. Finally, the MIA serves to 
identify any disproportionate impacts on manufacturer subgroups, 
including small business manufacturers.
    The quantitative part of the MIA primarily relies on the GRIM, an 
industry cash flow model with inputs specific to this rulemaking. The 
key GRIM inputs include data on the industry cost structure, unit 
production costs, product shipments, manufacturer markups, and 
investments in R&D and manufacturing capital required to produce 
compliant products. The key GRIM outputs are the INPV, which is the sum 
of industry annual cash flows over the analysis period, discounted 
using the industry weighted average cost of capital, and the impact to 
domestic manufacturing employment. The model uses standard accounting 
principles to estimate the impacts of more stringent energy 
conservation standards on a given industry by comparing changes in INPV 
and domestic manufacturing employment between a no-new-standards case 
and the various standards cases. To capture the uncertainty relating to 
manufacturer pricing strategies following amended standards, the GRIM 
estimates a range of possible impacts under different scenarios.
    The qualitative part of the MIA addresses manufacturer 
characteristics and market trends. Specifically, the MIA considers such 
factors as a potential standard's impact on manufacturing capacity, 
competition within the industry, the cumulative impact of other DOE and 
non-DOE regulations, and impacts on manufacturer subgroups. The 
complete MIA is outlined in chapter 12 of the direct final rule TSD.
    DOE conducted the MIA for this rulemaking in three phases. In Phase 
1 of the MIA, DOE prepared a profile of the refrigerators, 
refrigerator-freezers, and freezers manufacturing industry based on the 
market and technology assessment and publicly available information. 
This included a top-down analysis of refrigerators, refrigerator-
freezers, and freezers manufacturers that DOE used to derive 
preliminary financial inputs for the GRIM (e.g., revenues; materials, 
labor, overhead, and depreciation expenses; selling, general, and 
administrative expenses (``SG&A''); and R&D expenses). DOE also used 
public sources of information to further calibrate its initial 
characterization of the refrigerators, refrigerator-freezers, and 
freezers manufacturing industry, including company filings of form 10-K 
from the SEC,\73\ corporate annual reports, the U.S. Census Bureau's 
Annual Survey of Manufactures (``ASM''),\74\ and reports from Dun & 
Bradstreet.\75\

---------------------------------------------------------------------------

    In Phase 2 of the MIA, DOE prepared a framework industry cash flow 
analysis to quantify the potential impacts of amended energy 
conservation standards. The GRIM uses several factors to determine a 
series of annual cash flows starting with the announcement of the 
standard and extending over a 30-year period following the compliance 
date of the standard. These factors include annual expected revenues, 
costs of sales, SG&A

[[Page 3066]]

and R&D expenses, taxes, and capital expenditures. In general, energy 
conservation standards can affect manufacturer cash flow in three 
distinct ways: (1) creating a need for increased investment, (2) 
raising production costs per unit, and (3) altering revenue due to 
higher per-unit prices and changes in sales volumes.
    In addition, during Phase 2, DOE developed interview guides to 
distribute to manufacturers of refrigerators, refrigerator-freezers, 
and freezers in order to develop other key GRIM inputs, including 
product and capital conversion costs, and to gather additional 
information on the anticipated effects of energy conservation standards 
on revenues, direct employment, capital assets, industry 
competitiveness, and subgroup impacts.
    In Phase 3 of the MIA, DOE conducted structured, detailed 
interviews with representative manufacturers. During these interviews, 
DOE discussed engineering, manufacturing, procurement, and financial 
topics to validate assumptions used in the GRIM and to identify key 
issues or concerns. As part of Phase 3, DOE also evaluated subgroups of 
manufacturers that may be disproportionately impacted by amended 
standards or that may not be accurately represented by the average cost 
assumptions used to develop the industry cash flow analysis. Such 
manufacturer subgroups may include small business manufacturers, low-
volume manufacturers (``LVMs''), niche players, and/or manufacturers 
exhibiting a cost structure that largely differs from the industry 
average. DOE identified two subgroups for a separate impact analysis: 
small business manufacturers and domestic LVMs. The small business 
subgroup is discussed in chapter 12 of the direct final rule TSD. The 
domestic LVM subgroup is discussed in section V.B.2.d of this document 
and in chapter 12 of the direct final rule TSD.
2. Government Regulatory Impact Model and Key Inputs
    DOE uses the GRIM to quantify the changes in cash flow due to 
amended standards that result in a higher or lower industry value. The 
GRIM uses a standard, annual discounted cash flow analysis that 
incorporates manufacturer costs, manufacturer markups, shipments, and 
industry financial information as inputs. The GRIM models change in 
costs, distribution of shipments, investments, and manufacturer margins 
that could result from an amended energy conservation standard. The 
GRIM spreadsheet uses the inputs to arrive at a series of annual cash 
flows, beginning in 2023 (the base year of the analysis) and continuing 
30 years from the analyzed compliance year.\76\ DOE calculated INPVs by 
summing the stream of annual discounted cash flows during this period. 
For manufacturers of refrigerators, refrigerator-freezers, and 
freezers, DOE used a real discount rate of 9.1 percent, which was 
derived from industry financials and then modified according to 
feedback received during manufacturer interviews.
---------------------------------------------------------------------------

    \76\ For the no-new-standards case and all TSLs except for the 
Recommended TSL, the analysis period ranges from 2023-2056. For the 
Recommended TSL, the analysis period ranges from 2023-2058 for the 
product classes listed in Table I.1 and 2023-2059 for the product 
classes listed in Table I.2.
---------------------------------------------------------------------------

    The GRIM calculates cash flows using standard accounting principles 
and compares changes in INPV between the no-new-standards case and each 
standards case. The difference in INPV between the no-new-standards 
case and a standards case represents the financial impact of the 
amended energy conservation standard on manufacturers. As discussed 
previously, DOE developed critical GRIM inputs using a number of 
sources, including publicly available data, results of the engineering 
analysis, results of the shipments analysis, and information gathered 
from industry stakeholders during the course of manufacturer 
interviews. The GRIM results are presented in section V.B.2 of this 
document. Additional details about the GRIM, the discount rate, and 
other financial parameters can be found in chapter 12 of the direct 
final rule TSD.
a. Manufacturer Production Costs
    Manufacturing more efficient products is typically more expensive 
than manufacturing baseline products due to the use of more complex 
components, which are typically more costly than baseline components. 
The changes in the MPCs of covered products can affect the revenues, 
gross margins, and cash flow of the industry. For a complete 
description of the MPCs, see chapter 5 of the direct final rule TSD.
b. Shipments Projections
    The GRIM estimates manufacturer revenues based on total unit 
shipment projections and the distribution of those shipments by 
efficiency level. Changes in sales volumes and efficiency mix over time 
can significantly affect manufacturer finances. For this analysis, the 
GRIM uses the NIA's annual shipment projections derived from the 
shipments analysis from the base year (2023) to 30 years from the 
analyzed compliance date.\77\ See chapter 9 of the direct final rule 
TSD for additional details.

c. Product and Capital Conversion Costs
    Amended energy conservation standards could cause manufacturers to 
incur conversion costs to bring their production facilities and product 
designs into compliance. DOE evaluated the level of conversion-related 
expenditures that would be needed to comply with each considered 
efficiency level in each product class. For the MIA, DOE classified 
these conversion costs into two major groups: (1) product conversion 
costs; and (2) capital conversion costs. Product conversion costs are 
investments in research, development, testing, marketing, and other 
non-capitalized costs necessary to make product designs comply with 
amended energy conservation standards. Capital conversion costs are 
investments in property, plant, and equipment necessary to adapt or 
change existing production facilities such that new compliant product 
designs can be fabricated and assembled.
Product Conversion Costs
    DOE based its estimates of the product conversion costs necessary 
to meet the varying efficiency levels on information from manufacturer 
interviews, the design paths analyzed in the engineering analysis, and 
market share and model count information. Generally, manufacturers 
preferred to meet amended standards with design options that were 
direct and relatively straight-forward component swaps, such as 
incrementally more efficiency compressors. However, at higher 
efficiency levels, manufacturers anticipated the need for platform 
redesigns. Efficiency levels that potentially necessitate significantly 
altered cabinet construction would require very large investments to 
update designs. Manufacturers noted that increasing foam thickness 
would require complete redesign of the cabinet, and potentially, the 
liner and shelving, should there be changes in interior volume. 
Additionally, extensive use of VIPs would require redesign of the 
cabinet to maximize the benefits of VIPs.
    Based on manufacturer feedback, DOE also estimated ``re-flooring'' 
costs associated with replacing obsolete display models in big-box 
stores (e.g., Lowe's, Home Depot, Best Buy) due to

[[Page 3067]]

more stringent standards. Some manufacturers stated that with a new 
product release, big-box retailers discount outdated display models, 
and manufacturers share any losses associated with discounting the 
retail price. The estimated re-flooring costs for each efficiency level 
were incorporated into the product conversion cost estimates, as DOE 
modeled the re-flooring costs as a marketing expense. Manufacturer data 
was aggregated to protect confidential information.
    DOE interviewed manufacturers accounting for approximately 81 
percent of domestic refrigerator, refrigerator-freezer, and freezer 
shipments. DOE scaled product conversion costs by model counts to 
account for the portion of companies that were not interviewed. In 
manufacturer interviews, DOE received feedback on the analyzed product 
classes. For non-represented product classes, for which there was less 
available data, DOE used model counts to scale the product conversion 
cost estimates for analyzed product classes. See chapter 10 of the 
direct final rule TSD for details on the mapping of analyzed product 
classes to non-represented product classes. See chapter 12 of the 
direct final rule TSD for details on product conversion costs.
Capital Conversion Costs
    DOE relied on information derived from manufacturer interviews and 
the engineering analysis to evaluate the level of capital conversion 
costs manufacturers would likely incur at the considered standard 
levels. During the interviews, manufacturers provided estimates and 
descriptions of the required tooling and plant changes that would be 
necessary to upgrade product lines to meet potential efficiency levels. 
Based on these inputs, DOE modeled incremental capital conversion costs 
for efficiency levels that could be reached with individual components 
swaps. However, based on feedback, DOE modeled major capital conversion 
costs when manufacturers would have to redesign their existing product 
platforms. DOE used information from manufacturer interviews to 
determine the cost of the manufacturing equipment and tooling necessary 
to implement complete redesigns.
    Increases in foam thickness require either reductions to interior 
volume or increases to exterior volume. Since most refrigerators, 
refrigerator-freezers, and freezers must fit within standard widths, 
increases in foam thickness could result in the loss of interior 
volume. The reduction of interior volume has significant consequences 
for manufacturing. In addition to redesigning the cabinet to increase 
the effectiveness of insulation, manufacturers must update all designs 
and tooling associated with the interior of the product. This could 
include the liner, shelving, drawers, and doors. Manufacturers would 
need to invest in significant new tooling to accommodate the changes in 
dimensions.
    To minimize reductions to interior volume, manufacturers may choose 
to adopt VIP technology. Extensive incorporation of VIPs into designs 
require significant upfront capital due to differences in the handling, 
storing, and manufacturing of VIPs as compared to typical polyurethane 
foams. These investments are incorporated into the conversion costs 
estimated in the MIA for efficiency levels that would likely 
necessitate VIP technology. VIPs are relatively fragile and must be 
protected from punctures and rough handling. If VIPs have leaks of any 
size, the panel will eventually lose much of its thermal insulative 
properties and structural strength. If already installed within a 
cabinet wall, a punctured VIP may significantly reduce the structural 
strength of the refrigerator, refrigerator-freezer, or freezer cabinet. 
As a result, VIPs require cautious handling during the manufacturing 
process. DOE did not receive detailed information about the percent of 
VIPs that are punctured during the manufacturing process. Manufacturers 
noted the need to allocate special warehouse space to ensure the VIPs 
are not jostled or roughly handled in the manufacturing environment. 
Furthermore, manufacturers anticipated the need for expansion of 
warehouse space to accommodate the storage of VIPs. VIPs require 
significantly more warehouse space than the polyurethane foams 
currently used in most refrigerators, refrigerator-freezers, and 
freezers. The application of VIPs can be challenging and requires 
significant investment in hard-tooling or robotic systems to ensure the 
panels are positioned properly within the cabinet or door. 
Manufacturers noted that producing cabinets with VIPs is much more 
labor- and time-intensive than producing cabinets with typical 
polyurethane foams. Particularly in high-volume factories, which can 
produce over a million refrigerator-freezers per year, the increase in 
production time associated in increased VIP usage would necessitate 
additional investment in manufacturing capacity to meet demand. The 
cost of extending production lines varies greatly by manufacturer, as 
it depends heavily on floor space availability in and around existing 
manufacturing plants.
    Higher volume manufacturers would generally have higher investments 
as they have more production lines and greater production capacity. For 
manufacturers of both PC 5 (``refrigerator-freezer--automatic defrost 
with bottom-mounted freezer without an automatic ice maker'') and PC 5A 
(``refrigerator-freezer--automatic defrost with bottom-mounted freezer 
with through-the-door ice service''), cabinet changes in one product 
class would likely necessitate improvements in the other product class 
as they often share the same architecture, tooling, and production 
lines.
    DOE estimated industry capital conversion costs by extrapolating 
the interviewed manufacturers' capital conversion costs for each 
product class to account for the market share of companies that were 
not interviewed. DOE used the shipments analysis to scale the capital 
conversion cost estimates of the analyzed product class to account for 
the non-represented product class. See chapter 12 of the direct final 
rule TSD for additional details on capital conversion costs.
    Manufacturers may follow different design paths to reach the 
various efficiency levels analyzed. An individual manufacturer's 
investments depend on a range of factors, including the company's 
current product offerings and product platforms, existing production 
facilities and infrastructure, and make vs. buy decisions for 
components. DOE's conversion cost methodology incorporated feedback 
from all manufacturers that took part in interviews and extrapolated 
industry values. While industry average values may not represent any 
single manufacturer, DOE's model provides reasonable estimates of 
industry-level investments.
    DOE adjusted the conversion cost estimates developed in support of 
the February 2023 NOPR to 2022$ for this analysis.
    In general, DOE assumes all conversion-related investments occur 
between the year of publication of the direct final rule and the year 
by which manufacturers must comply with the new or amended standard. 
The conversion cost figures used in the GRIM can be found in section 
V.B.2 of this document. For additional information on the estimated 
capital and product conversion costs, see chapter 12 of the direct 
final rule TSD.
d. Manufacturer Markup Scenarios
    MSPs include direct manufacturing production costs (i.e., labor, 
materials,

[[Page 3068]]

and overhead estimated in DOE's MPCs) and all non-production costs 
(i.e., SG&A, R&D, and interest), along with profit. To calculate the 
MSPs in the GRIM, DOE applied manufacturer markups to the MPCs 
estimated in the engineering analysis for each product class and 
efficiency level. Modifying these manufacturer markups in the standards 
case yields different sets of impacts on manufacturers. For the MIA, 
DOE modeled two standards-case scenarios to represent uncertainty 
regarding the potential impacts on prices and profitability for 
manufacturers following the implementation of amended energy 
conservation standards: (1) a preservation-of-gross-margin-percentage 
scenario; and (2) a preservation-of-operating-profit scenario. These 
scenarios lead to different manufacturer markup values that, when 
applied to the MPCs, result in varying revenue and cash flow impacts.
    Under the preservation-of-gross-margin-percentage scenario, DOE 
applied a single uniform ``gross margin percentage'' across all 
efficiency levels, which assumes that manufacturers would be able to 
maintain the same amount of profit as a percentage of revenues at all 
efficiency levels within a product class. As manufacturer production 
costs increase with efficiency, this scenario implies that the per-unit 
dollar profit will increase. DOE assumed a gross margin percentage of 
21 percent for all freestanding product classes and 29 percent for all 
built-in product classes.\78\ Manufacturers tend to believe it is 
optimistic to assume that they would be able to maintain the same gross 
margin percentage as their production costs increase, particularly for 
minimally efficient products. Therefore, this scenario represents a 
high bound of industry profitability under an amended energy 
conservation standard.
---------------------------------------------------------------------------

    \78\ The gross margin percentages of 21 percent and 29 percent 
are based on manufacturer markups of 1.26 and 1.40 percent, 
respectively.
---------------------------------------------------------------------------

    In the preservation-of-operating-profit scenario, as the cost of 
production goes up under a standards case, manufacturers are generally 
required to reduce their manufacturer markups to a level that maintains 
base-case operating profit. DOE implemented this scenario in the GRIM 
by lowering the manufacturer markups at each TSL to yield approximately 
the same earnings before interest and taxes in the standards case as in 
the no-new-standards case in the year after the expected compliance 
date of the amended standards. The implicit assumption behind this 
scenario is that the industry can only maintain its operating profit in 
absolute dollars after the standard takes effect.
    A comparison of industry financial impacts under the two scenarios 
is presented in section V.B.2.a of this document.
3. Discussion of MIA Comments
    For this direct final rule, DOE considered comments it had received 
regarding its MIA presented in the February 2023 NOPR. The approach 
used for this direct final rule is largely the same approach DOE had 
used for the February 2023 NOPR analysis.
    In response to the February 2023 NOPR, AHAM stated that 
manufacturers may need to significantly redesign products in several 
classes to comply with the proposed DOE standards. In some high-volume 
product classes, AHAM asserted that there are no or very few shipments 
of products that meet the proposed standards. AHAM stated that this 
indicates that even when compliant models exist, they may not represent 
real-world shipments. AHAM commented that for other product classes, 
there is considerable variation in the availability of compliant models 
and shipments. AHAM added that in many instances, there are few 
compliant models and no reported shipments of compliant products, 
suggesting that substantial redesign efforts may be required across the 
market. (AHAM, No. 69 at pp. 2-3)
    DOE relied on multiple sources, including feedback from 
confidential manufacturer interviews and the design paths analyzed in 
the engineering analysis, to estimate the likely levels of redesign and 
investment required to meet each analyzed efficiency level. As 
discussed in section IV.J.2.c of this document, meeting higher 
efficiency levels may require product redesigns, particularly for 
efficiency levels that necessitate changes to the cabinet structure 
(i.e., changes to insulation such as increasing wall thickness or 
incorporating VIPs). Those costs are incorporated into the MIA. 
Regarding AHAM's concerns about low shipments at higher efficiency 
levels, DOE incorporated data from stakeholders into the shipments 
analysis for this direct final rule analysis. DOE used confidential 
aggregate historical shipments data from 2015-2022 provided by AHAM to 
calibrate the total shipments for standard-size refrigerator-freezers, 
compact refrigerators, upright freezers, chest freezers, and built-in 
refrigerator-freezers. For this direct final rule, DOE also used the 
AHAM-provided estimates for the efficiency distributions based on 
shipments for standard-size refrigerator-freezers and compact freezers. 
See section IV.G of this document for additional information on the 
shipments analysis.
    In response to the February 2023 NOPR, Whirlpool commented that a 
large decrease in INPV would stifle innovation as manufacturers would 
be forced to invest product development resources to meet the amended 
standards and potentially lay off U.S. production employees. 
(Whirlpool, No. 70 at p. 5)
    As discussed in section IV.J.2.c of this document, DOE's analysis 
shows that as efficiency levels increase, more manufacturers would need 
to dedicate more financial, engineering, laboratory, and marketing 
resources to updating products to meet more stringent standards. DOE 
accounts for those investments in the MIA (see section V.B.2.a of this 
document). However, DOE disagrees with the assertion that redesigning 
products to improve energy efficiency is in opposition to product 
innovation. As indicated by manufacturers' participation in the 
Environmental Protection Agency's (EPA) voluntary ENERGY STAR program 
and the estimated shipments that meet ENERGY STAR levels, manufacturers 
and consumers consider energy efficiency a product attribute. Of the 63 
refrigerator, refrigerator-freezer, and freezer original equipment 
manufacturers (OEMs) identified, approximately 46 OEMs manufacture 
models that meet ENERGY STAR levels and certify those models with the 
ENERGY STAR program. Approximately 22 percent of refrigerator, 
refrigerator-freezer, and freezer shipments already meet ENERGY STAR 
levels. Regarding the potential for a reduction in direct employment as 
a result of amended standards, DOE provides a range of potential 
quantitative impacts to direct employment and a discussion of the 
potential qualitative impacts to direct employment in section V.B.2.b 
of this document. Most major manufacturers with U.S. production 
facilities currently produce a portion of their products outside of the 
United States (e.g., Mexico). Adopting an amended standard that 
necessitates large increases in labor content or large expenditures to 
re-tool facilities could cause manufacturers to reevaluate domestic 
production siting options. See section V.B.2.b of this document for 
additional details on potential impacts to direct employment. DOE 
further notes, that Whirlpool is a party to the Joint Agreement and is 
supportive of the

[[Page 3069]]

recommended standard adopted in this direct final rule.
    Whirlpool commented that adoption of the proposed standard levels 
could make it difficult for multi-brand companies like Whirlpool to 
differentiate their products and product lines from other manufacturers 
as models become more technologically complex and costly. Whirlpool 
added that this could lead to the elimination of certain product 
segments and result in lost energy savings as consumers switch to more 
energy-intensive product types. (Whirlpool, No. 70 at pp. 7-8)
    DOE uses the GRIM, as described in section IV.J.2 of this document, 
to determine the quantitative impacts on the refrigerators, 
refrigerator-freezer, and freezer industry as a whole. DOE recognizes 
that the industry impacts do not apply evenly across manufacturers. 
Many manufacturers would need to update certain product designs to meet 
amended standard levels. However, DOE expects that manufacturers would 
still be able to differentiate their products and product lines by 
various factors (e.g., price, technologies, consumer features, energy 
efficiency). At the adopted level, all analyzed product classes will be 
required to meet efficiency levels below max-tech levels. Thus, DOE 
does not expect manufacturers would need to implement all analyzed 
design options across their product portfolio to meet the adopted 
levels. Furthermore, in this direct final rule, DOE is adopting the 
Recommended TSL, which would require lower efficiency levels for high-
volume product classes such as PC 5A and PC 7, as compared to the 
levels proposed in the February 2023 NOPR. Additionally, AHAM, a trade 
organization representing the interests of their members, including 
Whirlpool and other refrigerator, refrigerator-freezer, and freezer 
OEMs, is a signatory of the Joint Agreement. As discussed in section 
IV.A.1 of this document, DOE is adopting energy allowances for special 
door and multi-door designs for some product classes. Therefore, DOE 
expects that these types of features and others will remain prevalent 
in the market and could offer means for product differentiation. See 
section IV.A.1 of this document for additional information on the 
energy use allowances.
    The California Investor-Owned Utilities (``CA IOUs'') noted the 
differences between PC 7 and PC 5A in DOE's proposed energy efficiency 
standards for refrigerators, refrigerator-freezers, and freezers. The 
CA IOUs commented that the main difference between the two classes is 
the cost of moving to the VIP side walls and doors at max-tech EL, with 
PC 7 having a substantially higher order of magnitude for capital 
conversion costs compared to PC 5A. The CA IOUs recommended revising 
the proposal to consider EL 5 for PC 7 instead of EL 4. The CA IOUs 
requested that DOE elaborate on the reason for the differences in cost. 
(CA IOUs, No. 72 at p. 5)
    DOE relied on manufacturer feedback, among other sources, to derive 
the estimated product and capital conversion costs at each efficiency 
level for each directly analyzed product class. There are many reasons 
why the incremental industry conversion costs at each efficiency level 
could vary between product classes. These reasons include but are not 
limited to differences in analyzed design options, production volume, 
the number of models that would require redesign, the number of OEMs 
engaged in manufacturing each product class, the age of the product 
families and/or production equipment, and location of the production 
facilities. For PC 7, manufacturers could include less VIPs to meet the 
required efficiency level at EL 4 compared to EL 5. At EL 4, 75 percent 
of the maximum area could incorporate VIPs whereas EL 5 could 
incorporate VIPs for the maximum area on sidewalls and doors. As 
discussed in section IV.J.2.c of this document, incorporation of VIPs 
into designs requires significant upfront capital due to differences in 
the handling, storing, and manufacturing of VIPs as compared to typical 
polyurethane foams. DOE estimates the difference in capital conversion 
costs to be $117.9 million between EL 4 and EL 5. For product 
conversion costs, extensive use of VIPs would require redesign of the 
cabinet to maximize the benefits of VIPs. DOE estimated the difference 
to be $18.8 million between EL 4 and EL 5, which is attributed to 
design efforts required to meet 75 percent of maximum area of VIPs at 
EL 4 and the maximum area of VIPs at EL 5. Although manufacturers may 
incorporate some VIPs (on side walls and doors) for EL 2 for PC 5A, EL 
2 may be achieved by component swaps rather than product redesign based 
on information gathered during manufacturer interviews. AHAM commented 
the cumulative regulatory burden is significant for home appliance 
manufacturers when redesigning products and product lines for consumer 
clothes dryers, residential clothes washers, conventional cooking 
products, refrigeration products, miscellaneous refrigeration products, 
and room air conditioners. (AHAM, No. 69 at p. 20) AHAM asserted that 
engineers will therefore need to spend all their time redesigning 
products to meet more stringent energy efficiency standards, pulling 
resources from other development efforts and business priorities. AHAM 
suggested that DOE could reduce cumulative regulatory burden by spacing 
out the timing of final rules, allowing more lead time by delaying the 
publication of final rules in the Federal Register after they have been 
issued, and reducing the stringency of standards such that fewer 
products would require redesign. (Id. At p. 21) AHAM urged DOE to fully 
review the cumulative impacts its rules will have on manufacturers (as 
well as consumers). AHAM suggested that this review should include 
examining the potential impact on the economy and inflation as a result 
of reducing INPV so significantly. (Id. At p. 22)
    DOE analyzes cumulative regulatory burden in accordance with 
section 13(g) of the Process Rule. DOE details the rulemakings and 
expected conversion expenses of Federal energy conservation standards 
that could impact refrigerator, refrigerator-freezer, and freezer OEMs 
that take effect approximately 3 years before the 2029 compliance date 
and 3 years after the 2030 compliance date in section V.B.2.e of this 
document. As shown in Table V.29 in section V.B.2.e of this document, 
DOE considers the potential cumulative regulatory burden from other DOE 
energy conservation standards rulemakings for consumer clothes dryers, 
residential clothes washers, conventional cooking products, 
refrigeration products, miscellaneous refrigeration products, and room 
air conditioners in this direct final rule analysis. Regarding AHAM's 
suggestion about spacing out the timing of final rules for home 
appliance rulemakings, DOE has statutory requirements under EPCA on the 
timing of rulemakings. For refrigerators, refrigerator-freezers, and 
freezers, consumer conventional cooking products, residential clothes 
washers, consumer clothes dryers, room air conditioners, and 
dishwashers, amended standards apply to covered products manufactured 3 
years after the date on which any new or amended standard is published. 
(42 U.S.C. 6295(m)(4)(A)(i)) For miscellaneous refrigeration products, 
amended standards apply 5 years after the date on which any new or 
amended standard is published. (42 U.S.C. 6295(l)(2)) However, the 
multi-product Joint Agreement recommends alternative compliance dates. 
As discussed in section of this document, the Joint

[[Page 3070]]

Agreement recommendations are in accordance with the statutory 
requirements of 42 U.S.C. 6295(p)(4) for the issuance of a direct final 
rule. Therefore, as compared to the EPCA-required lead time, 
manufacturers will have additional time to meet amended standards for 
refrigerators, refrigerator-freezers, and freezers in this direct final 
rule.
    Regarding examining the cumulative impacts of energy conservation 
standards rulemakings on manufacturers and consumers, DOE must follow 
specific statutory criteria for prescribing new or amended standards 
for covered products, including refrigerators, refrigerator-freezers, 
and freezers. An amended standard must be designed to achieve the 
maximum improvement in energy efficiency that is determined to be 
technologically feasible and economically justified. (42 U.S.C. 
6295(o)(2)(A) and 42 U.S.C. 6295(o)(3)(B)) In its assessment of whether 
standards are economically justified, DOE considers the impact of the 
standard on manufacturers and consumers. DOE analyzes the impacts to 
manufacturers in accordance with section 13 of the Process Rule and the 
impacts to consumers in accordance with section 14 of the Process Rule. 
Although DOE does not analyze the cumulative burden on consumers, 
section V.B.1.a of this document discusses the economic impact of 
amended standards on individual consumers, which is the main impact 
consumers will face with a final amended energy conservation standard.
    AHAM stated that it cannot comment on the accuracy of DOE's 
approach for including how manufacturers might or might not recover 
potential investments (i.e., the accuracy of DOE's manufacturer markup 
scenarios) but that AHAM supports DOE's intent in the microwave ovens 
supplemental notice of proposed rulemaking (``SNOPR'') (``August 2022 
SNOPR'') energy conservation standards rulemaking to include those 
costs and investments in the actual costs of products and retail 
prices. 87 FR 52282. AHAM urged DOE to apply the same conceptual 
approach used in the August 2022 SNOPR in this refrigerator/freezer and 
all future rulemakings (i.e., to analyze a conversion-cost-recovery 
manufacturer markup scenario). (AHAM, No. 69 at p. 18)
    As discussed in section IV.J.2.d of this document, DOE modeled two 
standards-case manufacturer markup scenarios to represent the 
uncertainty regarding the potential impacts on prices and profitability 
for manufacturers following the implementation of amended energy 
conservation standards. For the February 2023 NOPR, DOE applied the 
preservation-of-gross-margin-percentage scenario to reflect an upper 
bound of industry profitability and a preservation-of-operating-profit 
scenario to reflect a lower bound of industry profitability under 
amended standards. DOE used these scenarios to reflect the range of 
realistic profitability impacts under more stringent standards. 
Manufacturing more efficient refrigerators, refrigerator-freezers, and 
freezers is generally more expensive than manufacturing baseline 
refrigerators, refrigerator-freezers, and freezers, as reflected by the 
MPCs estimated in the engineering analysis. Under the preservation-of-
gross-margin scenario for refrigerators, refrigerator-freezers, and 
freezers, incremental increases in MPCs at higher efficiency levels 
result in an increase in per-unit dollar profit per unit sold. In 
interviews, multiple manufacturers asserted that they would likely need 
to reduce manufacturer markups under more stringent standards to remain 
competitive in the marketplace. Therefore, the preservation of gross-
margin-scenario represents the upper bound of industry profitability 
under amended standards. Applying the approach used in the microwave 
ovens rulemaking (i.e., a conversion-cost-recovery scenario) would 
result in manufacturers increasing manufacturer markups under amended 
standards. Based on information gathered during confidential interviews 
in support of the February 2023 NOPR and a review of financial 
statements of companies engaged in manufacturing refrigerators, 
refrigerator-freezers, and freezers, DOE does not expect that the 
refrigerators, refrigerator-freezers, and freezers industry would 
increase manufacturer markups under an amended standard. Furthermore, 
in response to the February 2023 NOPR, DOE did not receive any public 
or confidential data indicating that industry would increase 
manufacturer markups in response to more stringent standards. 
Therefore, DOE maintained the two manufacturer markup scenarios from 
the February 2023 NOPR for this direct final rule analysis.

K. Emissions Analysis

    The emissions analysis consists of two components. The first 
component estimates the effect of potential energy conservation 
standards on power sector and site (where applicable) combustion 
emissions of CO<INF>2</INF>, NO<INF>X</INF>, SO<INF>2</INF>, and Hg. 
The second component estimates the impacts of potential standards on 
emissions of two additional greenhouse gases, CH<INF>4</INF> and 
N<INF>2</INF>O, as well as the reductions in emissions of other gases 
due to ``upstream'' activities in the fuel production chain. These 
upstream activities comprise extraction, processing, and transporting 
fuels to the site of combustion.
    The analysis of electric power sector emissions of CO<INF>2</INF>, 
NO<INF>X</INF>, SO<INF>2</INF>, and Hg uses emissions intended to 
represent the marginal impacts of the change in electricity consumption 
associated with amended or new standards. The methodology is based on 
results published for the AEO, including a set of side cases that 
implement a variety of efficiency-related policies. The methodology is 
described in appendix 13A in the direct final rule TSD. The analysis 
presented in this notice uses projections from AEO2023. Power sector 
emissions of CH<INF>4</INF> and N<INF>2</INF>O from fuel combustion are 
estimated using Emission Factors for Greenhouse Gas Inventories 
published by the Environmental Protection Agency (EPA).\79\
---------------------------------------------------------------------------

    \79\ Available at www.epa.gov/sites/production/files/2021-04/documents/emission-factors_apr2021.pdf (last accessed July 12, 
2021).
---------------------------------------------------------------------------

    FFC upstream emissions, which include emissions from fuel 
combustion during extraction, processing, and transportation of fuels, 
and ``fugitive'' emissions (direct leakage to the atmosphere) of 
CH<INF>4</INF> and CO<INF>2</INF>, are estimated based on the 
methodology described in chapter 15 of the direct final rule TSD.
    The emissions intensity factors are expressed in terms of physical 
units per megawatt-hour (``MWh'') or million British thermal units 
(``MMBtu'') of site energy savings. For power sector emissions, 
specific emissions intensity factors are calculated by sector and end 
use. Total emissions reductions are estimated using the energy savings 
calculated in the national impact analysis.
1. Air Quality Regulations Incorporated in DOE's Analysis
    DOE's no-new-standards case for the electric power sector reflects 
the AEO, which incorporates the projected impacts of existing air 
quality regulations on emissions. AEO2023 generally represents current 
legislation and environmental regulations, including recent government 
actions, that were in place at the time of preparation of AEO2023, 
including the emissions control programs discussed in the following 
paragraphs.\80\
---------------------------------------------------------------------------

    \80\ For further information, see the Assumptions to AEO2023 
report that sets forth the major assumptions used to generate the 
projections in the Annual Energy Outlook. Available at www.eia.gov/outlooks/aeo/assumptions/ (last accessed July 13, 2023).

---------------------------------------------------------------------------

[[Page 3071]]

    SO<INF>2</INF> emissions from affected electric generating units 
(``EGUs'') are subject to nationwide and regional emissions cap-and-
trade programs. Title IV of the Clean Air Act sets an annual emissions 
cap on SO<INF>2</INF> for affected EGUs in the 48 contiguous States and 
the District of Columbia (``DC''). (42 U.S.C. 7651 et seq.) 
SO<INF>2</INF> emissions from numerous States in the eastern half of 
the United States are also limited under the Cross-State Air Pollution 
Rule (``CSAPR''). 76 FR 48208 (Aug. 8, 2011). CSAPR requires these 
States to reduce certain emissions, including annual SO<INF>2</INF> 
emissions, and went into effect as of January 1, 2015.\81\ AEO2023 
incorporates implementation of CSAPR, including the update to the CSAPR 
ozone season program emission budgets and target dates issued in 2016. 
81 FR 74504 (Oct. 26, 2016). Compliance with CSAPR is flexible among 
EGUs and is enforced through the use of tradable emissions allowances. 
Under existing EPA regulations, for states subject to SO<INF>2</INF> 
emissions limits under CSAPR, any excess SO<INF>2</INF> emissions 
allowances resulting from the lower electricity demand caused by the 
adoption of an efficiency standard could be used to permit offsetting 
increases in SO<INF>2</INF> emissions by another regulated EGU.
---------------------------------------------------------------------------

    \81\ CSAPR requires states to address annual emissions of 
SO<INF>2</INF> and NO<INF>X</INF>, precursors to the formation of 
fine particulate matter (``PM<INF>2.5</INF>'') pollution, in order 
to address the interstate transport of pollution with respect to the 
1997 and 2006 PM<INF>2.5</INF> National Ambient Air Quality 
Standards (``NAAQS''). CSAPR also requires certain states to address 
the ozone season (May-September) emissions of NO<INF>X</INF>, a 
precursor to the formation of ozone pollution, in order to address 
the interstate transport of ozone pollution with respect to the 1997 
ozone NAAQS. 76 FR 48208 (Aug. 8, 2011). EPA subsequently issued a 
supplemental rule that included an additional five states in the 
CSAPR ozone season program; 76 FR 80760 (Dec. 27, 2011) 
(Supplemental Rule), and EPA issued the CSAPR Update for the 2008 
ozone NAAQS. 81 FR 74504 (Oct. 26, 2016).
---------------------------------------------------------------------------

    However, beginning in 2016, SO<INF>2</INF> emissions began to fall 
as a result of the Mercury and Air Toxics Standards (``MATS'') for 
power plants. 77 FR 9304 (Feb. 16, 2012). The direct final rule 
establishes power plant emission standards for mercury, acid gases, and 
non-mercury metallic toxic pollutants. In order to continue operating, 
coal plants must have either flue gas desulfurization or dry sorbent 
injection systems installed. Both technologies, which are used to 
reduce acid gas emissions, also reduce SO<INF>2</INF> emissions. 
Because of the emissions reductions under the MATS, it is unlikely that 
excess SO<INF>2</INF> emissions allowances resulting from the lower 
electricity demand would be needed or used to permit offsetting 
increases in SO<INF>2</INF> emissions by another regulated EGU. 
Therefore, energy conservation standards that decrease electricity 
generation will generally reduce SO<INF>2</INF> emissions. DOE 
estimated SO<INF>2</INF> emissions reduction using emissions factors 
based on AEO2023.
    CSAPR also established limits on NO<INF>X</INF> emissions for 
numerous States in the eastern half of the United States. Energy 
conservation standards would have little effect on NO<INF>X</INF> 
emissions in those States covered by CSAPR emissions limits if excess 
NO<INF>X</INF> emissions allowances resulting from the lower 
electricity demand could be used to permit offsetting increases in 
NO<INF>X</INF> emissions from other EGUs. In such case, NO<INF>X</INF> 
emissions would remain near the limit even if electricity generation 
goes down. Depending on the configuration of the power sector in the 
different regions and the need for allowances, however, NO<INF>X</INF> 
emissions might not remain at the limit in the case of lower 
electricity demand. That would mean that standards might reduce 
NO<INF>X</INF> emissions in covered States. Despite this possibility, 
DOE has chosen to be conservative in its analysis and has maintained 
the assumption that standards will not reduce NO<INF>X</INF> emissions 
in States covered by CSAPR. Standards would be expected to reduce 
NO<INF>X</INF> emissions in the States not covered by CSAPR. DOE used 
AEO2023 data to derive NO<INF>X</INF> emissions factors for the group 
of States not covered by CSAPR.
    The MATS limit mercury emissions from power plants, but they do not 
include emissions caps and, as such, DOE's energy conservation 
standards would be expected to slightly reduce Hg emissions. DOE 
estimated mercury emissions reduction using emissions factors based on 
AEO2023, which incorporates the MATS.

L. Monetizing Emissions Impacts

    As part of the development of this direct final rule, for the 
purpose of complying with the requirements of Executive Order 12866, 
DOE considered the estimated monetary benefits from the reduced 
emissions of CO<INF>2</INF>, CH<INF>4</INF>, N<INF>2</INF>O, 
NO<INF>X</INF>, and SO<INF>2</INF> that are expected to result from 
each of the TSLs considered. In order to make this calculation 
analogous to the calculation of the NPV of consumer benefit, DOE 
considered the reduced emissions expected to result over the lifetime 
of products shipped in the projection period for each TSL. This section 
summarizes the basis for the values used for monetizing the emissions 
benefits and presents the values considered in this direct final rule.
    To monetize the benefits of reducing GHG emissions, this analysis 
uses the interim estimates presented in the Technical Support Document: 
Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates 
Under Executive Order 13990 published in February 2021 by the IWG.
1. Monetization of Greenhouse Gas Emissions
    DOE estimates the monetized benefits of the reductions in emissions 
of CO<INF>2</INF>, CH<INF>4</INF>, and N<INF>2</INF>O by using a 
measure of the SC of each pollutant (e.g., SC-CO<INF>2</INF>). These 
estimates represent the monetary value of the net harm to society 
associated with a marginal increase in emissions of these pollutants in 
a given year, or the benefit of avoiding that increase. These estimates 
are intended to include (but are not limited to) climate-change-related 
changes in net agricultural productivity, human health, property 
damages from increased flood risk, disruption of energy systems, risk 
of conflict, environmental migration, and the value of ecosystem 
services.
    For this direct final rule, DOE considered comments it had received 
regarding its approach for monetizing greenhouse gas emissions in the 
February 2023 NOPR. The approach used for this direct final rule is 
largely the same approach DOE had used for the February 2023 NOPR 
analysis.
    The attorneys general (AGs) of TN, AL, et al. commented that DOE's 
misguided use of the SC-GHG estimates is a significant problem with the 
proposed standards. The AGs of TN, AL, et al. attached as evidence 
their comment letter in response to DOE's proposed standards for 
consumer conventional cooking products, in which they expressed 
detailed concerns about the IWG estimates. The AGs of TN, AL, et al. 
noted that the reversal of the preliminary injunction that a coalition 
of States received in Louisiana v. Biden, 585 F. Supp. 3d 840 (W.D. La. 
2022) does not change the criticisms in the aforementioned comment 
letter. (The AGs of TN, AL, et al., No. 68 at pp. 1-2)
    The IWG's SC-GHG estimates were developed over many years, using 
transparent process, peer-reviewed methodologies, the best science 
available at the time of that process, and with input from the public. 
A number of criticisms raised in the comment letter attached by the AGs 
of TN, AL, et al. were addressed by the IWG in its February 2021 SC-GHG 
TSD, and previous parts of this section summarized the IWG's 
conclusions on

[[Page 3072]]

key issues, including the question of discount rates cited by the 
Competitive Enterprise Institute (``CEI''). The IWG's 2016 TSD \82\ and 
the 2017 National Academies report provide detailed discussions of the 
ways in which the modeling underlying the development of the SC-GHG 
estimates addressed quantified sources of uncertainty. In the February 
2021 SC-GHG TSD, the IWG stated that the models used to produce the 
interim estimates do not include all of the important physical, 
ecological, and economic impacts of climate change recognized in the 
climate change literature. For these same impacts, the science 
underlying their ``damage functions'' lags behind the most recent 
research. In the judgment of the IWG, these and other limitations 
suggest that the range of four interim SC-GHG estimates presented in 
the TSD likely underestimate societal damages from GHG emissions. The 
IWG is in the process of assessing how best to incorporate the latest 
peer-reviewed science and the recommendations of the National Academies 
to develop an updated set of SC-GHG estimates.

    AHAM objected to DOE using the social cost of carbon and other 
monetization of emissions reductions benefits in its analysis of the 
factors EPCA requires DOE to balance in determining the appropriate 
standard. AHAM stated that while it may be acceptable for DOE to 
continue its current practice of examining the SCC and monetization of 
other emissions reductions benefits as informational so long as the 
underlying interagency analysis is transparent and vigorous, the 
monetization analysis should not impact the TSLs DOE selects as a new 
or amended standard. (AHAM, No. 69 at pp. 22-23) The AGs of TN, AL, et 
al. stated that even if it is important to take into account emissions 
reductions when considering the need for national energy conservation 
(as DOE has claimed), the IWG estimates are unlawful and poor methods 
for doing so. The AGs of TN, AL, et al. concluded that the IWG's SC-GHG 
estimates are fundamentally flawed and are an unreliable metric on 
which to base administrative action. (The AGs of TN, AL, et al., No. 68 
at pp. 1-2)
    As stated in section III.F.1.f of this document, DOE accounts for 
the environmental and public health benefits associated with the more 
efficient use of energy, including those connected to global climate 
change, as they are important to take into account when considering the 
need for national energy conservation. (See 42 U.S.C. 
6295(o)(2)(B)(i)(IV)) In addition, Executive Order 13563, which was re-
affirmed on January 21, 2021, stated that each agency must, among other 
things: ``select, in choosing among alternative regulatory approaches, 
those approaches that maximize net benefits (including potential 
economic, environmental, public health and safety, and other 
advantages; distributive impacts; and equity).'' For these reasons, DOE 
includes the monetized value of emissions reductions in its evaluation 
of potential standard levels. While the benefits associated with 
reduction of GHG emissions inform DOE's evaluation of potential 
standards, the action of proposing or adopting specific standards is 
not ``based on'' the SC-GHG values, as DOE would reach the same 
conclusion regarding the economic justification of standards presented 
in this direct final rule without considering the social cost of 
greenhouse gases.
    DOE exercises its own judgment in presenting monetized climate 
benefits as recommended by applicable Executive orders, and DOE would 
reach the same conclusion presented in this proposed rulemaking in the 
absence of the social cost of greenhouse gases. That is, the social 
costs of greenhouse gases, whether measured using the February 2021 
interim estimates presented by the Interagency Working Group on the 
Social Cost of Greenhouse Gases or by another means, did not affect the 
rule ultimately proposed by DOE.
    DOE estimated the global social benefits of CO<INF>2</INF>, 
CH<INF>4</INF>, and N<INF>2</INF>O reductions using SC-GHG values that 
were based on the interim values presented in the Technical Support 
Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim 
Estimates under Executive Order 13990, published in February 2021 by 
the IWG. The SC-GHG is the monetary value of the net harm to society 
associated with a marginal increase in emissions in a given year, or 
the benefit of avoiding that increase. In principle, the SC-GHG 
includes the value of all climate change impacts, including (but not 
limited to) changes in net agricultural productivity, human health 
effects, property damage from increased flood risk and natural 
disasters, disruption of energy systems, risk of conflict, 
environmental migration, and the value of ecosystem services. The SC-
GHG therefore, reflects the societal value of reducing emissions of the 
gas in question by one metric ton. The SC-GHG is the theoretically 
appropriate value to use in conducting benefit-cost analyses of 
policies that affect CO<INF>2</INF>, N<INF>2</INF>O, and CH<INF>4</INF> 
emissions. As a member of the IWG involved in the development of the 
February 2021 SC-GHG TSD, DOE agrees that the interim SC-GHG estimates 
represent the most appropriate estimate of the SC-GHG until revised 
estimates have been developed reflecting the latest, peer-reviewed 
science.
    The SC-GHG estimates presented here were developed over many years, 
using transparent process, peer-reviewed methodologies, the best 
science available at the time of that process, and with input from the 
public. Specifically, in 2009, the IWG, that included the DOE and other 
executive branch agencies and offices was established to ensure that 
agencies were using the best available science and to promote 
consistency in the social cost of carbon (SC-CO<INF>2</INF>) values 
used across agencies. The IWG published SC-CO<INF>2</INF> estimates in 
2010 that were developed from an ensemble of three widely cited 
integrated assessment models (IAMs) that estimate global climate 
damages using highly aggregated representations of climate processes 
and the global economy combined into a single modeling framework. The 
three IAMs were run using a common set of input assumptions in each 
model for future population, economic, and CO<INF>2</INF> emissions 
growth, as well as equilibrium climate sensitivity--a measure of the 
globally averaged temperature response to increased atmospheric 
CO<INF>2</INF> concentrations. These estimates were updated in 2013 
based on new versions of each IAM. In August 2016 the IWG published 
estimates of the social cost of methane (SC-CH<INF>4</INF>) and nitrous 
oxide (SC-N<INF>2</INF>O) using methodologies that are consistent with 
the methodology underlying the SC-CO<INF>2</INF> estimates. The 
modeling approach that extends the IWG SC-CO<INF>2</INF> methodology to 
non-CO<INF>2</INF> GHGs has undergone multiple stages of peer review. 
The SC-CH<INF>4</INF> and SC-N<INF>2</INF>O estimates were developed by 
Marten et al.\83\ and underwent a standard double-blind peer review 
process prior to journal publication. In 2015, as part of the response 
to public comments received to a 2013 solicitation for comments on the 
SC-CO<INF>2</INF> estimates, the IWG announced a National Academies of 
Sciences, Engineering, and Medicine

[[Page 3073]]

review of the SC-CO<INF>2</INF> estimates to offer advice on how to 
approach future updates to ensure that the estimates continue to 
reflect the best available science and methodologies. In January 2017, 
the National Academies released their final report, ``Valuing Climate 
Damages: Updating Estimation of the Social Cost of Carbon Dioxide,'' 
and recommended specific criteria for future updates to the SC-
CO<INF>2</INF> estimates, a modeling framework to satisfy the specified 
criteria, and both near-term updates and longer-term research needs 
pertaining to various components of the estimation process (National 
Academies, 2017).\84\ Shortly thereafter, in March 2017, President 
Trump issued Executive Order 13783, which disbanded the IWG, withdrew 
the previous TSDs, and directed agencies to ensure SC-CO<INF>2</INF> 
estimates used in regulatory analyses are consistent with the guidance 
contained in OMB's Circular A-4, ``including with respect to the 
consideration of domestic versus international impacts and the 
consideration of appropriate discount rates'' (E.O. 13783, section 5I). 
Benefit-cost analyses following E.O. 13783 used SC-GHG estimates that 
attempted to focus on the U.S.-specific share of climate change damages 
as estimated by the models and were calculated using two discount rates 
recommended by Circular A-4, 3 percent and 7 percent. All other 
methodological decisions and model versions used in SC-GHG calculations 
remained the same as those used by the IWG in 2010 and 2013, 
respectively.

    On January 20, 2021, President Biden issued Executive Order 13990, 
which re-established the IWG and directed it to ensure that the U.S. 
Government's estimates of the social cost of carbon and other 
greenhouse gases reflect the best available science and the 
recommendations of the National Academies (2017). The IWG was tasked 
with first reviewing the SC-GHG estimates currently used in Federal 
analyses and publishing interim estimates within 30 days of the E.O. 
that reflect the full impact of GHG emissions, including by taking 
global damages into account. The interim SC-GHG estimates published in 
February 2021 are used here to estimate the climate benefits for this 
proposed rulemaking. The E.O. instructs the IWG to undertake a fuller 
update of the SC-GHG estimates by January 2022 that takes into 
consideration the advice of the National Academies (2017) and other 
recent scientific literature. The February 2021 SC-GHG TSD provides a 
complete discussion of the IWG's initial review conducted under 
E.O.13990. In particular, the IWG found that the SC-GHG estimates used 
under E.O. 13783 fail to reflect the full impact of GHG emissions in 
multiple ways.
    First, the IWG found that the SC-GHG estimates used under E.O. 
13783 fail to fully capture many climate impacts that affect the 
welfare of U.S. citizens and residents, and those impacts are better 
reflected by global measures of the SC-GHG. Examples of omitted effects 
from the E.O. 13783 estimates include direct effects on U.S. citizens, 
assets, and investments located abroad, supply chains, U.S. military 
assets and interests abroad, and tourism, and spillover pathways such 
as economic and political destabilization and global migration that can 
lead to adverse impacts on U.S. national security, public health, and 
humanitarian concerns. In addition, assessing the benefits of U.S. GHG 
mitigation activities requires consideration of how those actions may 
affect mitigation activities by other countries, as those international 
mitigation actions will provide a benefit to U.S. citizens and 
residents by mitigating climate impacts that affect U.S. citizens and 
residents. A wide range of scientific and economic experts have 
emphasized the issue of reciprocity as support for considering global 
damages of GHG emissions. If the United States does not consider 
impacts on other countries, it is difficult to convince other countries 
to consider the impacts of their emissions on the United States. The 
only way to achieve an efficient allocation of resources for emissions 
reduction on a global basis--and so benefit the U.S. and its citizens--
is for all countries to base their policies on global estimates of 
damages. As a member of the IWG involved in the development of the 
February 2021 SC-GHG TSD, DOE agrees with this assessment and, 
therefore, in this proposed rule DOE centers attention on a global 
measure of SC-GHG. This approach is the same as that taken in DOE 
regulatory analyses from 2012 through 2016. A robust estimate of 
climate damages that accrue only to U.S. citizens and residents does 
not currently exist in the literature. As explained in the February 
2021 SC-GHG TSD, existing estimates are both incomplete and an 
underestimate of total damages that accrue to the citizens and 
residents of the U.S. because they do not fully capture the regional 
interactions and spillovers discussed above, nor do they include all of 
the important physical, ecological, and economic impacts of climate 
change recognized in the climate change literature. As noted in the 
February 2021 SC-GHG TSD, the IWG will continue to review developments 
in the literature, including more robust methodologies for estimating a 
U.S.-specific SC-GHG value, and explore ways to better inform the 
public of the full range of carbon impacts. As a member of the IWG, DOE 
will continue to follow developments in the literature pertaining to 
this issue.
    Second, the IWG found that the use of the social rate of return on 
capital (7 percent under current OMB Circular A-4 guidance) to discount 
the future benefits of reducing GHG emissions inappropriately 
underestimates the impacts of climate change for the purposes of 
estimating the SC-GHG. Consistent with the findings of the National 
Academies (2017) and the economic literature, the IWG continued to 
conclude that the consumption rate of interest is the theoretically 
appropriate discount rate in an intergenerational context,\85\ and 
recommended that discount rate uncertainty and relevant aspects of 
intergenerational ethical considerations be accounted for in selecting 
future discount rates.

    Furthermore, the damage estimates developed for use in the SC-GHG 
are estimated in consumption-equivalent terms, and so an application of 
OMB Circular A-4's guidance for regulatory analysis would then use the 
consumption discount rate to calculate

[[Page 3074]]

the SC-GHG. DOE agrees with this assessment and will continue to follow 
developments in the literature pertaining to this issue. DOE also notes 
that while OMB Circular A-4, as published in 2003, recommends using 3-
percent and 7-percent discount rates as ``default'' values, Circular A-
4 also reminds agencies that ``different regulations may call for 
different emphases in the analysis, depending on the nature and 
complexity of the regulatory issues and the sensitivity of the benefit 
and cost estimates to the key assumptions.'' On discounting, Circular 
A-4 recognizes that ``special ethical considerations arise when 
comparing benefits and costs across generations,'' and Circular A-4 
acknowledges that analyses may appropriately ``discount future costs 
and consumption benefits . . . at a lower rate than for 
intragenerational analysis.'' In the 2015 ``Response to Comments on the 
Social Cost of Carbon for Regulatory Impact Analysis,'' OMB, DOE, and 
the other IWG members recognized that ``Circular A-4 is a living 
document'' and ``the use of 7 percent is not considered appropriate for 
intergenerational discounting. There is wide support for this view in 
the academic literature, and it is recognized in Circular A-4 itself.'' 
Thus, DOE concludes that a 7-percent discount rate is not appropriate 
to apply to value the social cost of greenhouse gases in the analysis 
presented in this analysis.
    To calculate the present and annualized values of climate benefits, 
DOE uses the same discount rate as the rate used to discount the value 
of damages from future GHG emissions, for internal consistency. That 
approach to discounting follows the same approach that the February 
2021 SC-GHG TSD recommends ``to ensure internal consistency--i.e., 
future damages from climate change using the SC-GHG at 2.5 percent 
should be discounted to the base year of the analysis using the same 
2.5-percent rate.'' DOE has also consulted the National Academies' 2017 
recommendations on how SC-GHG estimates can ``be combined in RIAs 
[regulatory impact analyses] with other cost and benefits estimates 
that may use different discount rates.'' The National Academies 
reviewed several options, including ``presenting all discount rate 
combinations of other costs and benefits with [SC-GHG] estimates.''
    As a member of the IWG involved in the development of the February 
2021 SC-GHG TSD, DOE agrees with the above assessment and will continue 
to follow developments in the literature pertaining to this issue. 
While the IWG works to assess how best to incorporate the latest, peer-
reviewed science to develop an updated set of SC-GHG estimates, it set 
the interim estimates to be the most recent estimates developed by the 
IWG prior to the group being disbanded in 2017. The estimates rely on 
the same models and harmonized inputs and are calculated using a range 
of discount rates. As explained in the February 2021 SC-GHG TSD, the 
IWG has recommended that agencies revert to the same set of four values 
drawn from the SC-GHG distributions based on three discount rates as 
were used in regulatory analyses between 2010 and 2016 and were subject 
to public comment. For each discount rate, the IWG combined the 
distributions across models and socioeconomic emissions scenarios 
(applying equal weight to each) and then selected a set of four values 
recommended for use in benefit-cost analyses: an average value 
resulting from the model runs for each of three discount rates (2.5 
percent, 3 percent, and 5 percent), plus a fourth value, selected as 
the 95th percentile of estimates based on a 3-percent discount rate. 
The fourth value was included to provide information on potentially 
higher-than-expected economic impacts from climate change. As explained 
in the February 2021 SC-GHG TSD, and DOE agrees, this update reflects 
the immediate need to have an operational SC-GHG for use in regulatory 
benefit-cost analyses and other applications that was developed using a 
transparent process, peer-reviewed methodologies, and the science 
available at the time of that process. Those estimates were subject to 
public comment in the context of dozens of proposed rulemakings as well 
as in a dedicated public comment period in 2013.
    There are a number of limitations and uncertainties associated with 
the SC-GHG estimates. First, the current scientific and economic 
understanding of discounting approaches suggests discount rates 
appropriate for intergenerational analysis in the context of climate 
change are likely to be less than 3 percent, near 2 percent or 
lower.\86\ Second, the IAMs used to produce these interim estimates do 
not include all of the important physical, ecological, and economic 
impacts of climate change recognized in the climate change literature 
and the science underlying their ``damage functions''--i.e., the core 
parts of the IAMs that map global mean temperature changes and other 
physical impacts of climate change into economic (both market and 
nonmarket) damages--lags behind the most recent research. For example, 
limitations include the incomplete treatment of catastrophic and non-
catastrophic impacts in the integrated assessment models, their 
incomplete treatment of adaptation and technological change, the 
incomplete way in which inter-regional and intersectoral linkages are 
modeled, uncertainty in the extrapolation of damages to high 
temperatures, and inadequate representation of the relationship between 
the discount rate and uncertainty in economic growth over long time 
horizons. Likewise, the socioeconomic and emissions scenarios used as 
inputs to the models do not reflect new information from the last 
decade of scenario generation or the full range of projections. The 
modeling limitations do not all work in the same direction in terms of 
their influence on the SC-CO<INF>2</INF> estimates. However, as 
discussed in the February 2021 SC-GHG TSD, the IWG has recommended 
that, taken together, the limitations suggest that the interim SC-GHG 
estimates used in this direct final rule likely underestimate the 
damages from GHG emissions. DOE concurs with this assessment.

assumptions, and parameters identical to the 2020-2050 estimates 
published by the IWG (which were based on EPA modeling). DOE expects 
additional climate benefits to accrue for any longer-life 
refrigerators, refrigerator-freezers, and freezers after 2070, but a 
lack of available SC-CO<INF>2</INF> estimates for emissions years 
beyond 2070 prevents DOE from monetizing these potential benefits in 
this analysis.

---------------------------------------------------------------------------

    DOE multiplied the CO<INF>2</INF> emissions reduction estimated for 
each year by the SC-CO<INF>2</INF> value for that year in each of the 
four cases. DOE adjusted the values to 2022$ using the implicit price 
deflator for gross domestic product (``GDP'') from the Bureau of 
Economic Analysis. To calculate a present value of the stream of 
monetary values, DOE discounted the values in each of the four cases 
using the specific discount rate that had been used to obtain the SC-
CO<INF>2</INF> values in each case.
b. Social Cost of Methane and Nitrous Oxide
    The SC-CH<INF>4</INF> and SC-N<INF>2</INF>O values used for this 
direct final rule were based on the values developed for the February 
2021 SC-GHG TSD. Table IV.14 shows the updated sets of SC-
CH<INF>4</INF> and SC-N<INF>2</INF>O estimates from the latest 
interagency update in 5-year increments from 2020 to 2050. The full set 
of annual values used is presented in appendix 14-A of the direct final 
rule TSD. To capture the uncertainties involved in regulatory impact 
analysis, DOE has determined it is appropriate to include all four sets 
of SC-CH<INF>4</INF> and SC-N<INF>2</INF>O values, as recommended by 
the IWG. DOE derived values after 2050 using the approach described 
above for the SC-CO<INF>2</INF>.

    DOE multiplied the CH<INF>4</INF> and N<INF>2</INF>O emissions 
reduction estimated for each year by the SC-CH<INF>4</INF> and SC-
N<INF>2</INF>O estimates for that year in each of the cases. DOE 
adjusted the values to 2022$ using the implicit price deflator for 
gross domestic product (``GDP'') from the Bureau of Economic Analysis. 
To calculate a present value of the stream of monetary values, DOE 
discounted the values in each of the cases using the specific discount 
rate that had been used to obtain the SC-CH<INF>4</INF> and SC-
N<INF>2</INF>O estimates in each case.

2. Monetization of Other Emissions Impacts

    For the direct final rule, DOE estimated the monetized value of 
NO<INF>X</INF> and SO<INF>2</INF> emissions reductions from electricity 
generation using benefit-per-ton estimates for that sector from the 
EPA's Benefits Mapping and Analysis Program.\89\ DOE used EPA's values 
for PM<INF>2.5</INF>-related benefits associated with NO<INF>X</INF> 
and SO<INF>2</INF> and for ozone-related benefits associated with 
NO<INF>X</INF> for 2025, 2030, and 2040, calculated with discount rates 
of 3 percent and 7 percent. DOE used linear interpolation

[[Page 3076]]

to define values for the years not given in the 2025 to 2040 period; 
for years beyond 2040, the values are held constant. DOE combined the 
EPA benefit-per-ton estimates with regional information on electricity 
consumption and emissions to define weighted-average national values 
for NO<INF>X</INF> and SO<INF>2</INF> as a function of sector (see 
appendix 14B of the NOPR TSD).

accessed July 19, 2023).
---------------------------------------------------------------------------

    DOE multiplied the site emissions reduction (in tons) in each year 
by the associated $/ton values, and then discounted each series using 
discount rates of 3 percent and 7 percent as appropriate.

M. Utility Impact Analysis

    The utility impact analysis estimates the changes in installed 
electrical capacity and generation projected to result for each 
considered TSL. The analysis is based on published output from the NEMS 
associated with AEO2023. NEMS produces the AEO Reference case, as well 
as a number of side cases that estimate the economy-wide impacts of 
changes to energy supply and demand. For the current analysis, impacts 
are quantified by comparing the levels of electricity sector 
generation, installed capacity, fuel consumption and emissions in the 
AEO2023 Reference case and various side cases. Details of the 
methodology are provided in the appendices to chapters 13 and 15 of the 
direct final rule TSD.
    The output of this analysis is a set of time-dependent coefficients 
that capture the change in electricity generation, primary fuel 
consumption, installed capacity and power sector emissions due to a 
unit reduction in demand for a given end use. These coefficients are 
multiplied by the stream of electricity savings calculated in the NIA 
to provide estimates of selected utility impacts of potential new or 
amended energy conservation standards.

N. Employment Impact Analysis

    DOE considers employment impacts in the domestic economy as one 
factor in selecting a standard. Employment impacts from new or amended 
energy conservation standards include both direct and indirect impacts. 
Direct employment impacts are any changes in the number of employees of 
manufacturers of the products subject to standards. The MIA addresses 
those impacts. Indirect employment impacts are changes in national 
employment that occur due to the shift in expenditures and capital 
investment caused by the purchase and operation of more efficient 
appliances. Indirect employment impacts from standards consist of the 
net jobs created or eliminated in the national economy, other than in 
the manufacturing sector being regulated, caused by (1) reduced 
spending by consumers on energy, (2) reduced spending on new energy 
supply by the utility industry, (3) increased consumer spending on the 
products to which the new standards apply and other goods and services, 
and (4) the effects of those three factors throughout the economy.
    One method for assessing the possible effects on the demand for 
labor of such shifts in economic activity is to compare sector 
employment statistics developed by the Labor Department's Bureau of 
Labor Statistics (``BLS''). BLS regularly publishes its estimates of 
the number of jobs per million dollars of economic activity in 
different sectors of the economy, as well as the jobs created elsewhere 
in the economy by this same economic activity. Data from BLS indicate 
that expenditures in the utility sector generally create fewer jobs 
(both directly and indirectly) than expenditures in other sectors of 
the economy.\90\ There are many reasons for these differences, 
including wage differences and the fact that the utility sector is more 
capital-intensive and less labor-intensive than other sectors. Energy 
conservation standards have the effect of reducing consumer utility 
bills. Because reduced consumer expenditures for energy likely lead to 
increased expenditures in other sectors of the economy, the general 
effect of efficiency standards is to shift economic activity from a 
less labor-intensive sector (i.e., the utility sector) to more labor-
intensive sectors (e.g., the retail and service sectors). Thus, the BLS 
data suggest that net national employment may increase due to shifts in 
economic activity resulting from energy conservation standards.

---------------------------------------------------------------------------

    DOE estimated indirect national employment impacts for the standard 
levels considered in this direct final rule using an input/output model 
of the U.S. economy called Impact of Sector Energy Technologies version 
4 (``ImSET'').\91\ ImSET is a special-purpose version of the ``U.S. 
Benchmark National Input-Output'' (``I-O'') model, which was designed 
to estimate the national employment and income effects of energy-saving 
technologies. The ImSET software includes a computer-based I-O model 
having structural coefficients that characterize economic flows among 
187 sectors most relevant to industrial, commercial, and residential 
building energy use.

Laboratory: Richland, WA. PNNL-24563.
---------------------------------------------------------------------------

    DOE notes that ImSET is not a general equilibrium forecasting 
model, and that the uncertainties involved in projecting employment 
impacts, especially changes in the later years of the analysis. Because 
ImSET does not incorporate price changes, the employment effects 
predicted by ImSET may over-estimate actual job impacts over the long 
run for this rule. Therefore, DOE used ImSET only to generate results 
for near-term timeframes (2029/30-2033/4), where these uncertainties 
are reduced. For more details on the employment impact analysis, see 
chapter 16 of the direct final rule TSD.

O. Other Comments

    As discussed previously, DOE considered relevant comments, data, 
and information obtained during its own rulemaking process in 
determining whether the recommended standards from the Joint Agreement 
are in accordance with 42 U.S.C. 6295(o). And while some of those 
comments were directed at specific aspects of DOE's analysis of the 
Joint Agreement under 42 U.S.C. 6295(o), others were more generally 
applicable to DOE's energy conservation standards rulemaking program as 
a whole. The ensuing discussion focuses on these general comments 
concerning energy conservation standards issued under EPCA.
1. Commerce Clause
    The AGs of TN, AL, et al. commented that DOE's approach to 
Congress's Commerce Clause is improper because precedent dictates that 
Congress can only regulate intrastate activity under the Commerce 
Clause when that activity ``substantially affects interstate 
commerce.'' (AGs of TN, AL, et al., No. 0068 at pp. 3-5) The AGs of TN, 
AL, et al. commented that for the proposed standards to reach the 
intrastate market for refrigerators, refrigerator-freezers, and 
freezers, DOE must show that the intrastate activity covered by 42 
U.S.C. 6291(17) and 6302(5) substantially affects the interstate market 
for those products and the proposed standards show no constitutional 
basis for applying the standards to intrastate commerce in 
refrigerators, refrigerator-freezers, and freezers. (Id.) The AGs of 
TN, AL, et al. added that if such an

[[Page 3077]]

analysis showed the intrastate market did not substantially affect the 
interstate market (and so was not properly the subject of Federal 
regulation), then DOE would be obligated to redo its cost-benefit 
analysis since the proposed standards would apply to a more limited set 
of products--those traveling interstate. (Id.) Finally, the AGs of TN, 
AL, et al. requested that even if DOE found that the intrastate market 
substantially affected interstate commerce, DOE should nevertheless 
exclude intrastate activities from the proposed standards to ``maintain 
a healthy balance of power between the States and the Federal 
Government.'' (Id. at 4-5)
    DOE responds that it believes the scope of both the standard 
proposed in the NOPR and the amended standard adopted in this direct 
final rule properly includes all refrigerators, refrigerator-freezers, 
and freezers distributed in commerce for personal use or consumption 
because intrastate state activity regulated by 42 U.S.C. 6291(17) and 
6302 is inseparable from and substantially affects interstate commerce. 
DOE has clear authority under EPCA to regulate the energy use of a 
variety of consumer products and certain commercial and industrial 
equipment, including the subject refrigerators, refrigerator-freezers, 
and freezers. See 42 U.S.C. 6295. Based on this statutory authority, 
DOE has a long-standing practice of issuing standards with the same 
scope as the standard in this direct final rule. For example, DOE has 
maintained a similar scope of products in the final rule that 
established the current standards for refrigerators, refrigerator-
freezers, and freezers, which was published on September 15, 2011 (76 
FR 57516), and in the final rule establishing the preceding set of 
standards for these products, published on April 28, 1997 (62 FR 
23102). DOE disagrees with the AGs of TN, AL, et al.'s contention that 
the Commerce Clause, the Tenth Amendment, the Major Questions Doctrine, 
or any canons of statutory construction limit DOE's clear and long-
standing authority under EPCA to adopt the standard, including its 
scope, in this direct final rule. A further discussion regarding the 
AGs of TN, AL, et al.'s federalism concerns can be found at section 
VI.E of this document.
2. National Academy of Sciences Report
    The National Academies of Sciences, Engineering, and Medicine 
(``NAS'') periodically appoint a committee to peer review the 
assumptions, models, and methodologies that DOE uses in setting energy 
conservation standards for covered products and equipment. The most 
recent such peer review was conducted in a series of meetings in 2020, 
and NAS issued the report \92\ in 2021 detailing its findings and 
recommendations on how DOE can improve its analyses and align them with 
best practices for cost-benefit analysis.

Setting Appliance and Equipment Standards. Washington, DC: The 
National Academies Press. Available at doi.org/10.17226/25992 (last 
accessed August 2, 2023).
---------------------------------------------------------------------------

    AHAM stated that despite previous requests from AHAM and others, 
DOE has failed to review and incorporate the recommendations of the NAS 
report, instead indicating that it will conduct a separate rulemaking 
process without such a process having been initiated. (AHAM, No. 69 at 
pp. 9-10) AHAM further stated that DOE seems to be ignoring the 
recommendations in the NAS Report and even conducting analysis that is 
opposite to the recommendations. AHAM commented that DOE cannot 
continue to perpetuate the errors in its analytical approach that have 
been pointed out by stakeholders and the NAS report as to do so will 
lead to arbitrary and capricious rules. (Id.)
    As discussed, the rulemaking process for establishing new or 
amended standards for covered products and equipment are specified at 
appendix A to subpart C of 10 CFR part 430. DOE periodically examines 
and revises these provisions in separate rulemaking proceedings. The 
recommendations provided in the 2011 NAS report, which pertain to the 
processes by which DOE analyzes energy conservation standards, will be 
considered by DOE in a separate rulemaking process.
3. Family Well-Being
    The AGs of TN, AL, et al. submitted a joint comment that DOE's 
proposed standards regulate an appliance that is commonly used in 
family kitchens, and the costs they impose affect every family's 
budget, forcing lower-income families to make difficult financial 
decisions. Therefore, the AGs of TN, AL, et al. requested that DOE 
provide the assessment required by section 654 of the Treasury and 
General Government Appropriations Act, 1999, which considers the impact 
of the Proposed Standards on family well-being. (The AGs of TN, AL, et 
al., No. 68 at pp. 5-6)
    Section 654 of the Treasury and General Government Appropriations 
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family 
Policymaking Assessment for any proposed rule or policy that may affect 
family well-being. Although this direct final rule would not have any 
impact on the autonomy or integrity of the family as an institution as 
defined, this rule could impact a family's well-being. When developing 
a Family Policymaking Assessment, agencies must assess whether: (1) the 
action strengthens or erodes the stability or safety of the family and, 
particularly, the marital commitment; (2) the action strengthens or 
erodes the authority and rights of parents in the education, nurture, 
and supervision of their children; (3) the action helps the family 
perform its functions, or substitutes governmental activity for the 
function; (4) the action increases or decreases disposable income or 
poverty of families and children; (5) the proposed benefits of the 
action justify the financial impact on the family; (6) the action may 
be carried out by State or local government or by the family; and 
whether (7) the action establishes an implicit or explicit policy 
concerning the relationship between the behavior and personal 
responsibility of youth, and the norms of society.
    DOE has considered how the proposed benefits of this rule compare 
to the possible financial impact on a family (the only factor listed 
that is relevant to this rule). As part of its rulemaking process, DOE 
must determine whether the energy conservation standards contained in 
this direct final rule are economically justified. As discussed in 
section V.C.1 of this document, DOE has determined that the standards 
are economically justified because the benefits to consumers far 
outweigh the costs to manufacturers. Families will also see LCC savings 
as a result of this rule. Moreover, as discussed further in section 
V.B.1 of this document, DOE has determined that for the for low-income 
households, average LCC savings and PBP at the considered efficiency 
levels are improved (i.e., higher LCC savings and lower payback period) 
as compared to the average for all households. Further, the standards 
will also result in climate and health benefits for families. Numerous 
individuals commented against proposed standards. Comments cited cost 
increases on consumers, narrowing of consumer choice, and government 
overregulation. (Individual Commenters, No. 47-53, 56, 58, 59 at p. 1)
    As discussed in section II.A of this document, DOE conducted 
numerous analyses in support of this direct final rule consistent with 
EPCA, which requires that DOE consider many factors, including those 
concerns raised

[[Page 3078]]

by commenters. Analyses include the potential negative impacts on 
consumers and manufacturers and an assessment of the impact relative to 
the cost and energy savings resulting from amended standards, which are 
discussed in further detail in sections IV.F, IV.H, and IV.J of this 
document. DOE conducted its engineering analysis to determine standards 
that are applicable to reducing energy consumption while remaining 
technologically feasible. The engineering analysis is discussed in 
greater detail throughout section IV.C of this document. DOE notes that 
the comments on government overregulation lack the necessary 
specificity to properly address them in this context. However, as 
mentioned above, DOE conducted the analysis in this rulemaking 
consistent with the requirements in EPCA and those used in past 
rulemakings for this product.

V. Analytical Results and Conclusions

    The following section addresses the results from DOE's analyses 
with respect to the considered energy conservation standards for 
refrigerators, refrigerator-freezers, and freezers. It addresses the 
TSLs examined by DOE, the projected impacts of each of these levels if 
adopted as energy conservation standards for refrigerators, 
refrigerator-freezers, and freezers, and the standards levels that DOE 
is adopting in this direct final rule. Additional details regarding 
DOE's analyses are contained in the direct final rule TSD supporting 
this document.

A. Trial Standard Levels

    In general, DOE typically evaluates potential amended standards for 
products and equipment by grouping individual efficiency levels for 
each class into TSLs. Use of TSLs allows DOE to identify and consider 
manufacturer cost interactions between the product classes, to the 
extent that there are such interactions, and market cross elasticity 
from consumer purchasing decisions that may change when different 
standard levels are set.
    In the analysis conducted for this direct final rule, DOE analyzed 
the benefits and burdens of six TSLs for refrigerators, refrigerator-
freezers, and freezers. DOE developed TSLs that combine efficiency 
levels for each analyzed product class. TSL 1 represents a modest 
increase in efficiency, corresponding to the lowest analyzed efficiency 
level above the baseline for each analyzed product class. TSL 2 
represents an increase in efficiency of 10 percent across the product 
classes analyzed, consistent with ENERGY STAR requirements, except for 
PC 10, for which a majority of consumers would experience a net cost at 
all considered ELs. Efficiency improvements for product class 10 were 
considered only for TSL 1 and max-tech TSL 6. TSL 3 increases the 
stringency for PCs 5, 5A, 7, 11A, and 18 and increases NES while 
keeping economic impacts on consumers relatively modest. TSL 4 is the 
Recommended TSL detailed in the Joint Agreement. TSL 4 increases the 
proposed standard level for PCs 3 and 9, as well as the expected NES, 
while average LCC savings are positive for every product class. TSL 4 
also corresponds to different compliance years than the other TSLs. 
Rather than a compliance year of 2027, for TSL 4, 2029 is the 
compliance year for the product classes listed in Table I.1 and 2030 is 
the compliance year for the product classes listed in Table I.2. TSL 5 
increases the proposed standard level for PC 5A and PC 7, decreases the 
proposed standard level for PC 9, and increases the expected overall 
NES, while average LCC savings remain positive for every product class. 
TSL 6 represents max-tech. DOE presents the results for the TSLs in 
this document, while the results for all efficiency levels that DOE 
analyzed are in the direct final rule TSD.
    Table V.1 presents the TSLs and the corresponding efficiency levels 
that DOE has identified for potential amended energy conservation 
standards for refrigerators, refrigerator-freezers, and freezers.

* DOE did not consider efficiency levels above baseline for PC 10 for TSLs 2-5.
** Recommended TSL from the Joint Agreement. This TSL also includes different standard levels for the non-representative PCs 4-BI, 5A-BI, 7-BI, 9-BI, 9A-
  BI and 12. The compliance year varies by product class. See the Joint Agreement for details.

    Section IV.C.3 shows the design options determined to be required 
for representative products of each analyzed class as a function of the 
TSLs.

B. Economic Justification and Energy Savings

1. Economic Impacts on Individual Consumers
    DOE analyzed the economic impacts on refrigerator, refrigerator-
freezer, and freezer consumers by looking at the effects that potential 
amended standards at each TSL would have on the LCC and PBP. DOE also 
examined the impacts of potential standards on selected consumer 
subgroups. These analyses are discussed in the following sections.
a. Life-Cycle Cost and Payback Period
    In general, higher-efficiency products affect consumers in two 
ways: (1) purchase price increases and (2) annual operating costs 
decrease. Inputs used for calculating the LCC and PBP include total 
installed costs (i.e., product price plus installation costs), and 
operating costs (i.e., annual energy use, energy prices, energy price 
trends, repair costs, and maintenance costs). The LCC calculation also 
uses product lifetime and a discount rate. Chapter 8 of the direct 
final rule TSD provides detailed information on the LCC and PBP 
analyses.
    Tables V.2 through V.21 show the LCC and PBP results for the TSLs 
considered for each product class. In the first of each pair of tables, 
the simple payback is measured relative to the baseline product. In the 
second table, the impacts are measured relative to the efficiency 
distribution in the in the no-new-standards case in the compliance year 
(see section IV.F.9 of this document). Because some consumers purchase 
products with higher efficiency in the no-new-standards case, the 
average savings are less than the difference between the average LCC of 
the baseline product and the average LCC at each TSL. The savings refer 
only to consumers who are affected by a standard at a given TSL. Those 
who already purchase a product with

[[Page 3079]]

efficiency at or above a given TSL are not affected. Consumers for whom 
the LCC increases at a given TSL experience a net cost.

b. Consumer Subgroup Analysis
    In the consumer subgroup analysis, DOE estimated the impact of the 
considered TSLs on low-income households and small businesses. Table 
V.22 compares the average LCC savings and PBP at each efficiency level 
for the low-income consumer subgroup with similar metrics for the 
entire consumer sample for PCs 3, 7, 9, and 10 (see section IV.I for an 
explanation of why other product classes are excluded). Table V.23 
provides a similar comparison for PC 11A for the small business 
subgroup. In all cases, the average LCC savings and PBP for low-income 
households at the considered efficiency levels are improved (i.e., 
higher LCC savings and lower payback period) from the average for all 
households. The LCC savings and payback period results for the small 
business subgroup for PC 11A are similar to those for all businesses. 
Chapter 11 of the direct final rule TSD presents the complete LCC and 
PBP results for the subgroups.

c. Rebuttable Presumption Payback
    As discussed in section IV.F.10 of this document, EPCA establishes 
a rebuttable presumption that an energy conservation standard is 
economically justified if the increased purchase cost for a product 
that meets the standard is less than three times the value of the 
first-year energy savings resulting from the standard. In calculating a 
rebuttable-presumption payback period for each of the considered TSLs, 
DOE used discrete values, and, as required by EPCA, based the energy 
use calculation on the DOE test procedures for refrigerators, 
refrigerator-freezers, and freezers. In contrast, the PBPs presented in 
section V.B.1.a of this document were calculated using distributions 
that reflect the range of energy use in the field.
    Table V.24 presents the rebuttable-presumption payback periods for 
the considered TSLs for refrigerators, refrigerator-freezers, and 
freezers. While DOE examined the rebuttable-presumption criterion, it 
considered whether the standard levels considered for this rule are 
economically justified through a more detailed analysis of the economic 
impacts of those levels, pursuant to 42 U.S.C. 6295(o)(2)(B)(i), that 
considers the full range of impacts to the consumer, manufacturer, 
Nation, and environment. The results of that analysis serve as the 
basis for DOE to definitively evaluate the economic justification for a 
potential standard level, thereby supporting or rebutting the results 
of any preliminary determination of economic justification.

2. Economic Impacts on Manufacturers
    DOE performed an MIA to estimate the impact of amended energy 
conservation standards on manufacturers of refrigerators, refrigerator-
freezers, and freezers. The next section describes the expected impacts 
on manufacturers at each considered TSL. Chapter 12 of the direct final 
rule TSD explains the analysis in further detail.
a. Industry Cash Flow Analysis Results
    In this section, DOE provides GRIM results from the analysis, which 
examines changes in the industry that would result from a standard. The 
following tables summarize the estimated financial impacts (represented 
by changes in INPV) of potential amended energy conservation standards 
on manufacturers of refrigerators, refrigerator-freezers, and freezers, 
as well as the conversion costs that DOE estimates manufacturers of 
refrigerators, refrigerator-freezers, and freezers would incur at each 
TSL.
    The impact of potential amended energy conservation standards was 
analyzed under two scenarios: (1) the preservation-of-gross-margin 
percentage; and (2) the preservation-of-operating-profit, as discussed 
in section IV.J.2.d of this document. The preservation-of-gross-margin 
percentages applies a ``gross margin percentage'' of 21 percent for all 
freestanding product classes and 29 percent for all built-in product 
classes, across all efficiency levels.\93\ This scenario assumes that a 
manufacturer's per-unit dollar profit would increase as MPCs increase 
in the standards cases and represents the upper-bound to industry 
profitability under potential new or amended energy conservation 
standards.
---------------------------------------------------------------------------

    \93\ The gross margin percentages of 21 percent and 29 percent 
are based on manufacturer markups of 1.26 and 1.40 percent, 
respectively.
---------------------------------------------------------------------------

    The preservation-of-operating-profit scenario reflects 
manufacturers' concerns about their inability to maintain margins as 
MPCs increase to reach more stringent efficiency levels. In this 
scenario, while manufacturers make the necessary investments required 
to convert their facilities to produce compliant products, operating 
profit does not change in absolute dollars and decreases as a 
percentage of revenue. The preservation-of-operating-profit scenario 
results in the lower (or more severe) bound to impacts of potential 
amended standards on industry.
    Each of the modeled scenarios results in a unique set of cash flows 
and corresponding INPV for each TSL. INPV is the sum of the discounted 
cash flows to the industry from the base year through the end of the 
analysis period (30 years from the analyzed compliance

[[Page 3086]]

year).\94\ The ``change in INPV'' results refer to the difference in 
industry value between the no-new-standards case and standards case at 
each TSL. To provide perspective on the short-run cash flow impact, DOE 
includes a comparison of free cash flow between the no-new-standards 
case and the standards case at each TSL in the year before amended 
standards would take effect. This figure provides an understanding of 
the magnitude of the required conversion costs relative to the cash 
flow generated by the industry in the no-new-standards case.
---------------------------------------------------------------------------

    \94\ The analysis period ranges from 2023-2056 for the no-new-
standards case and all TSLs, except for TSL 4 (the Recommended TSL). 
The analysis period for the Recommended TSL ranges from 2023-2058 
for the product classes listed in Table I.1 and 2023-2059 for the 
product classes listed in Table I.2.
---------------------------------------------------------------------------

    Conversion costs are one-time investments for manufacturers to 
bring their manufacturing facilities and product designs into 
compliance with potential amended standards. As described in section 
IV.J.2.c of this document, conversion cost investments occur between 
the year of publication of the direct final rule and the year by which 
manufacturers must comply with the new standard. The conversion costs 
can have a significant impact on the short-term cash flow of the 
industry and generally result in lower free cash flow in the period 
between the publication of the direct final rule and the compliance 
date of potential amended standards. Conversion costs are independent 
of the manufacturer markup scenarios and are not presented as a range 
in this analysis.

** TSL 4 (i.e., the Recommended TSL) represents the change in free cash flow in 2029.
*** In 2029, the no-new-standards case free cash flow is $413.1 million.

    The following cash flow discussion refers to product classes as 
defined in Table I.1 in section I of this document and the efficiency 
levels and design options as detailed in Tables IV.5 through IV.7 in 
section IV.C.3 of this document.
    At TSL 1, the standard represents a modest increase in efficiency, 
corresponding to the lowest analyzed efficiency level above the 
baseline for each analyzed product class. The change in INPV is 
expected to range from -1.3 to -0.3 percent. At this level, free cash 
flow is estimated to decrease by 7.0 percent compared to the no-new-
standards case value of $414.5 million in the year 2026, the year 
before the 2027 standards year. Currently, approximately 24 percent of 
domestic refrigerator, refrigerator-freezer, and freezer shipments meet 
the efficiencies required at TSL 1. See Table V.27 for the percentage 
of 2023 shipments that meet each TSL by product class.
    The design options DOE analyzed primarily included implementing 
more efficient single-speed compressors. For PC 5,\95\ PC 5A, PC 5-BI, 
PC 10, and PC 17, the design options analyzed included implementing 
higher-efficiency variable-speed compressors. DOE also analyzed 
implementing BLDC fan motors and variable defrost for some product 
classes. DOE expects manufacturers would likely need to increase wall 
thickness for some of PC 11A models to meet TSL 1 efficiencies. At this 
level, capital conversion costs are minimal since most manufacturers 
can achieve TSL 1 efficiencies with relatively minor component changes. 
Product conversion costs may be necessary for developing, qualifying, 
sourcing, and testing new components. DOE expects industry to incur 
some re-flooring costs as manufacturers redesign baseline products to 
meet the efficiency levels required by TSL 1. DOE estimates capital 
conversion costs of $10.8 million and product conversion costs of $71.7 
million. Conversion costs total $82.5 million.
---------------------------------------------------------------------------

    \95\ The engineering analysis modeled PC 5 (23.0 AV) as 
requiring a higher-efficiency single-speed compressor to meet TSL 1 
efficiencies and modeled PC 5 (30.0 AV) as requiring a variable-
speed compressor system to meet TSL 1 efficiencies.
---------------------------------------------------------------------------

    At TSL 1, the shipment-weighted average MPC for all refrigerators, 
refrigerator-freezers, and freezers is expected to increase by 1.6 
percent relative to the no-new-standards case shipment-weighted average 
MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. 
In the preservation-of-gross-margin percentage scenario, the minor 
increase in cashflow from the higher MSP is slightly outweighed by the 
$82.5 million in conversion costs, causing a negligible change in INPV 
at TSL 1 under this scenario. Under the preservation-of-operating-
profit scenario, manufacturers earn the same per-unit operating profit 
as would be earned in the no-new-standards case, but manufacturers do 
not earn additional profit from their investments. In this scenario, 
the manufacturer markup decreases in 2028, the year after the analyzed 
2027 compliance year. This reduction in the manufacturer markup and the 
$82.5 million in conversion costs incurred by manufacturers cause a 
slightly negative change in INPV at TSL 1 under the preservation-of-
operating-profit scenario. See section IV.J.2.d of this document for 
details on the manufacturer markup scenarios.
    At TSL 2, the standard represents an increase in efficiency of 
approximately 10 percent across all analyzed product classes, 
consistent with ENERGY STAR requirements, except for PC 10. The change 
in INPV is expected to range from -2.2 to -0.7 percent. At this level, 
free cash flow is estimated to decrease by 12.4 percent compared to the 
no-new-standards case value of $414.5 million in the year 2026, the 
year before the 2027 standards year. Currently, approximately 26 
percent of domestic refrigerator, refrigerator-

[[Page 3087]]

freezer, and freezer shipments meet the efficiencies required at TSL 2.
    The design options DOE analyzed include implementing similar design 
options as TSL 1, such as more efficient compressors, BLDC fans, and 
variable defrost. For PC 3, the design options included implementing 
incrementally more efficient single-speed compressors and variable 
defrost. For PC 7, the design options analyzed included implementing 
variable-speed compressors. For PC 3 and PC 7, TSL 2 corresponds to EL 
2. For PC 10, TSL 2 corresponds to baseline efficiency. For the 
remaining product classes, the efficiencies required at TSL 2 are the 
same as TSL 1. The increase in conversion costs from the prior TSL is 
entirely due to the increased efficiencies required for PC 3 and PC 7. 
Capital conversion costs may be necessary for updated tooling and 
additional stations to test more variable-speed compressors. Product 
conversion costs may be necessary for developing, qualifying, sourcing, 
and testing variable-speed compressors and associated electronics. DOE 
expects industry to incur slightly more re-flooring costs compared to 
TSL 1. DOE estimates capital conversion costs of $22.3 million and 
product conversion costs of $121.7 million. Conversion costs total 
$144.0 million.
    At TSL 2, the shipment-weighted average MPC for all refrigerators, 
refrigerator-freezers, and freezers is expected to increase by 2.3 
percent relative to the no-new-standards case shipment-weighted average 
MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. 
In the preservation-of-gross-margin-percentage scenario, the slight 
increase in cashflow from the higher MSP is outweighed by the $144.0 
million in conversion costs, causing a slightly negative change in INPV 
at TSL 2 under this scenario. Under the preservation-of-operating-
profit scenario, the manufacturer markup decreases in 2028. This 
reduction in the manufacturer markup and the $144.0 million in 
conversion costs incurred by manufacturers cause a slightly negative 
change in INPV at TSL 2 under the preservation-of-operating-profit 
scenario.
    At TSL 3, the standard represents an increased stringency for PC 5, 
PC 5A, PC 7, PC 11A, and PC 18 and increased NES while keeping economic 
impacts on consumers modest. The change in INPV is expected to range 
from -10.6 to -8.0 percent. At this level, free cash flow is estimated 
to decrease by 66.7 percent compared to the no-new-standards case value 
of $414.5 million in the year 2026, the year before the 2027 standards 
year. Currently, approximately 18 percent of domestic refrigerator, 
refrigerator-freezer, and freezer shipments meet the efficiencies 
required at TSL 3.
    In addition to the design options DOE analyzed at TSL 2, the design 
options analyzed for PC 5 include implementing higher-efficiency 
variable-speed compressors and incorporating partial VIP for larger 
capacity (i.e., adjusted volume) products. DOE expects that PC 5A 
products would likely also need to incorporate some partial VIP. For PC 
7, the deign options analyzed included implementing more efficient 
variable-speed compressors. Additionally, for the compact-size PC 18, 
DOE expects manufacturers may need to increase cabinet wall thickness. 
For PC 5, PC 5A, PC 11A, and PC 18, TSL 3 corresponds to EL 2. For PC 
7, TSL 3 corresponds to EL 3. For the remaining product classes, the 
efficiencies required at TSL 3 are the same as TSL 2. The increase in 
conversion costs from the prior TSL are driven by the efficiencies 
required for PC 5 and PC 5A due to their large market share (together, 
these product classes account for approximately 30 percent of total 
shipments) and the design options required to meet this level. Capital 
conversion costs may be necessary for new tooling for VIP placement as 
well as new testing stations for high-efficiency components. Product 
conversion costs may be necessary for developing, qualifying, sourcing, 
and testing new components. For products implementing VIPs, product 
conversion costs may be necessary for prototyping and testing for VIP 
placement, design, and sizing. For PC 5 and PC 5A, DOE understands the 
two product classes often share the same production lines, with shared 
cabinet architecture and tooling. DOE expects manufacturers would 
likely need to incorporate some VIPs into PC 5A designs, but not to the 
extent required at TSL 5 and TSL 6. Thus, for the 10 OEMs that 
manufacture both PC 5 and PC 5A, DOE expects manufacturers could 
implement similar cabinet upgrades (i.e., partial VIP) for PC 5 and PC 
5A designs to achieve the efficiencies required at this level. DOE 
expects industry to incur re-flooring costs as manufacturers redesign 
their products to meet the efficiency levels required by TSL 3. DOE 
estimates capital conversion costs of $378.1 million and product 
conversion costs of $314.7 million. Conversion costs total $629.8 
million.
    At TSL 3, the shipment-weighted average MPC for all refrigerators, 
refrigerator-freezers, and freezers is expected to increase by 4.0 
percent relative to the no-new-standards case shipment-weighted average 
MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. 
In the preservation-of-gross-margin-percentage scenario, the increase 
in cashflow from the higher MSP is outweighed by the $692.8 million in 
conversion costs, causing a negative change in INPV at TSL 3 under this 
scenario. Under the preservation-of-operating-profit scenario, the 
manufacturer markup decreases in 2028. This reduction in the 
manufacturer markup and the $692.8 million in conversion costs incurred 
by manufacturers cause a negative change in INPV at TSL 3 under the 
preservation-of-operating-profit scenario.
    At TSL 4 (i.e., the Recommended TSL), the standard represents an 
increased stringency for PC 3 and PC 9, as well as the expected NES, 
while maintaining positive average LCC savings for every analyzed 
product class. The change in INPV is expected to range from -10.3 to -
7.8 percent. At this level, free cash flow is estimated to decrease by 
51.7 percent compared to the no-new-standards case value of $413.1 
million in the year 2029, the year before the 2030 standards year.\96\ 
Currently, approximately 14 percent of domestic refrigerator, 
refrigerator-freezer, and freezer shipments meet the efficiencies 
required at TSL 4.
---------------------------------------------------------------------------

    \96\ For the Recommended TSL, the compliance year varies by 
product class. For the product classes listed in Table I.1, the 
analyzed compliance year is 2029. For the product classes listed in 
Table I.2, the analyzed compliance year is 2030. The product classes 
associated with the 2030 compliance year account for approximately 
68 percent of total shipments.
---------------------------------------------------------------------------

    In addition to the design options DOE analyzed at TSL 3, the design 
options analyzed for PC 3 products include implementing the highest-EER 
single-speed compressors or variable-speed compressors. For PC 9, the 
design options analyzed included the highest-EER variable-speed 
compressors. For PC 3, TSL 4 corresponds to EL 3. For PC 9, TSL 4 
corresponds to EL 2. For the remaining directly analyzed product 
classes, the efficiencies required at TSL 4 are the same as TSL 3. At 
this level, the increase in conversion costs is entirely driven by the 
higher efficiency levels required for PC 3 and PC 9, which together 
account for approximately 33 percent of current industry shipments. 
Many manufacturers of these product classes would need to update their 
platforms to integrate variable-speed compressors. For PC 5 and PC 5A, 
DOE understands the two product classes often share the same production 
lines, with shared cabinet architecture and tooling. DOE expects 
industry to incur

[[Page 3088]]

more re-flooring costs compared to TSL 3. DOE estimates capital 
conversion costs of $471.8 million and product conversion costs of 
$358.5 million. Conversion costs total $830.3 million.
    At TSL 4, the shipment-weighted average MPC for all refrigerator, 
refrigerator-freezers, and freezers is expected to increase by 4.8 
percent relative to the no-new-standards case shipment-weighted average 
MPC for all refrigerators, refrigerator-freezers, and freezers in 2030. 
In the preservation-of-gross-margin-percentage scenario, the increase 
in cashflow from the higher MSP is outweighed by the $830.3 million in 
conversion costs, causing a negative change in INPV at TSL 4 under this 
scenario. Under the preservation-of-operating-profit scenario, the 
manufacturer markup decreases in 2031, the year after the analyzed 2030 
compliance year.\97\ This reduction in the manufacturer markup and the 
$830.3 million in conversion costs incurred by manufacturers cause a 
negative change in INPV at TSL 4 under the preservation-of-operating-
profit scenario.
---------------------------------------------------------------------------

    \97\ The compliance year for the Recommended TSL varies by 
product class. For PC 1, PC 1A, PC 2, PC 3, PC 3A, PC 4, PC 5, PC 6, 
PC 7, and PC 9, the compliance year is 2030. For the remaining 
product classes, the compliance year is 2029.
---------------------------------------------------------------------------

    At TSL 5, the standard represents the maximum NPV. The change in 
INPV is expected to range from -21.7 to -17.2 percent. At this level, 
free cash flow is estimated to decrease by 140.1 percent compared to 
the no-new-standards case value of $414.5 million in the year 2026, the 
year before the 2027 standards year. Currently, approximately 14 
percent of domestic refrigerator, refrigerator-freezer, and freezer 
shipments meet the efficiencies required at TSL 5.
    In addition to the design options DOE analyzed at TSL 4, the design 
options analyzed for PC 5A includes implementing VIPs on all of the 
cabinet surface (side walls and doors) and for PC 7 includes 
implementing VIPs on roughly 75 percent of the cabinet surface. For PC 
5A, TSL 5 corresponds to EL 3. For PC 7, TSL 5 corresponds to EL 4. For 
PC 9, TSL 5 corresponds to EL 1, the same efficiency level required for 
TSL 3. For the remaining product classes, the efficiencies required at 
TSL 5 are the same as TSL 4. The increase in conversion costs compared 
to the prior TSL is entirely driven by the higher efficiency level 
required for PC 5A and PC 7, which likely necessitates incorporating 
some VIPs. In interviews, some manufacturers stated that their existing 
PC 5A and PC 7 platforms cannot reach this efficiency level and would 
require a platform redesign, which would likely mean new cases, liners, 
and fixtures. DOE expects slightly more re-flooring costs compared to 
the prior TSL as manufacturers redesign products to meet the required 
efficiencies. DOE estimates capital conversion costs of $945.3 million 
and product conversion costs of $458.7 million. Conversion costs total 
$1.40 billion.
    At TSL 5, the large conversion costs result in a free cash flow 
dropping below zero in the years before the standards year. The 
negative free cash flow calculation indicates manufacturers may need to 
access cash reserves or outside capital to finance conversion efforts.
    At TSL 5, the shipment-weighted average MPC for all refrigerators, 
refrigerator-freezers, and freezers is expected to increase by 7.0 
percent relative to the no-new-standards case shipment-weighted average 
MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. 
In the preservation-of-gross-margin-percentage scenario, the increase 
in cashflow from the higher MSP is outweighed by the $1.40 billion in 
conversion costs, causing a moderately negative change in INPV at TSL 5 
under this scenario. Under the preservation-of-operating-profit 
scenario, the manufacturer markup decreases in 2028. This reduction in 
the manufacturer markup and the $1.40 billion in conversion costs 
incurred by manufacturers cause a large decrease in INPV at TSL 5 under 
the preservation-of-operating-profit scenario.
    At TSL 6, the standard reflects max-tech for all product classes. 
The change in INPV is expected to range from -37.2 to -26.5 percent. At 
this level, free cash flow is estimated to decrease by 240.2 percent 
compared to the no-new-standards case value of $414.5 million in the 
year 2026, the year before the 2027 standards year. Currently, 
approximately 0.9 percent of domestic refrigerator, refrigerator-
freezer, and freezer shipments meet the efficiencies required at TSL 6.
    At max-tech levels, manufacturers would likely need to implement 
the best-available-efficiency VSC, forced-convection heat exchangers 
with multi-speed BLDC fans, variable defrost, and increase in cabinet 
wall thickness for some classes (e.g., compact refrigerators and both 
standard-size and compact chest freezers). Manufacturers would also 
likely incorporate VIP doors for PC 10 and PC 18 and VIPs for roughly 
half the cabinet surface (typically side walls and doors for an upright 
cabinet) for all other classes. At TSL 6, only a few manufacturers 
offer any products that meet the efficiencies required. For PC 3, which 
accounts for approximately 25 percent of annual shipments, no OEMs 
currently offer products that meet the efficiency level required. For 
PC 5, which accounts for approximately 21 percent of annual shipments, 
DOE estimates that seven out of 22 OEMs currently offer products that 
meet the efficiency level required. For PC 7, which accounts for 
approximately 11 percent of annual shipments, only one out of the 11 
OEMs currently offers products that meet the efficiency level required.
    The efficiencies required by TSL 6 could require a major renovation 
of existing facilities and completely new refrigerator, refrigerator-
freezer, and freezer platforms for many OEMs. In interviews, some 
manufacturers stated that they are physically constrained at their 
current production location and would therefore need to expand their 
existing production facility or move to an entirely new facility. These 
manufacturers stated that their current manufacturing locations are at 
capacity and cannot accommodate the additional labor required to 
implement VIPs. DOE expects industry to incur more re-flooring costs 
compared to TSL 5 as all display models below max-tech efficiency would 
need to be replaced due to the more stringent standard. DOE estimates 
capital conversion costs of $1.68 billion and product conversion costs 
of $711.4 million. Conversion costs total $2.39 billion.
    At TSL 6, the large conversion costs result in a free cash flow 
dropping below zero in the years before the 2027 standards year. The 
negative free cash flow calculation indicates manufacturers may need to 
access cash reserves or outside capital to finance conversion efforts.
    At TSL 6, the shipment-weighted average MPC for all refrigerators, 
refrigerator-freezers, and freezers is expected to increase by 16.8 
percent relative to the no-new-standards case shipment-weighted average 
MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. 
In the preservation-of-gross-margin-percentage scenario, the increase 
in cashflow from the higher MSP is outweighed by the $2.39 billion in 
conversion costs, causing a large negative change in INPV at TSL 6 
under this scenario. Under the preservation-of-operating-profit 
scenario, the manufacturer markup decreases in 2028. This reduction in 
the manufacturer markup and the $2.39 billion in conversion costs 
incurred by manufacturers causes a significant decrease in INPV at TSL 
6 under the preservation-of-operating-profit scenario.

b. Direct Impacts on Employment
    To quantitatively assess the potential impacts of amended energy 
conservation standards on direct employment in the refrigerators, 
refrigerator-freezers, and freezers industry, DOE used the GRIM to 
estimate the domestic labor expenditures and number of direct employees 
in the no-new-standards case and in each of the standards cases during 
the analysis period. For the direct final rule, DOE used the most up-
to-date information available. DOE calculated these values using 
statistical data from the 2021 ASM,\98\ BLS employee compensation 
data,\99\ results of the engineering analysis, and manufacturer 
interviews conducted in support of the February 2023 NOPR.
---------------------------------------------------------------------------

    \98\ U.S. Census Bureau, Annual Survey of Manufactures. 
``Summary Statistics for Industry Groups and Industries in the U.S 
(2021).'' Available at www.census.gov/programs-surveys/asm/data.html

Employee Compensation--March 2023. June 16, 2023. Available at

---------------------------------------------------------------------------

    Labor expenditures related to product manufacturing depend on the 
labor intensity of the product, the sales volume, and an assumption 
that wages remain fixed in real terms over time. The total labor 
expenditures in each year are calculated by multiplying the total MPCs 
by the labor percentage of MPCs. The total labor expenditures in the 
GRIM were then converted to total production employment levels by 
dividing production labor expenditures by the average fully burdened 
wage multiplied by the average number of hours worked per year per 
production worker. To do this, DOE relied on the ASM inputs: Production 
Workers Annual Wages, Production Workers Annual Hours, Production 
Workers for Pay Period, and Number of Employees. DOE also relied on the 
BLS employee compensation data to determine the fully burdened wage 
ratio. The fully burdened wage ratio factors in paid leave, 
supplemental pay, insurance, retirement and savings, and legally 
required benefits.
    The number of production employees is then multiplied by the U.S. 
labor Percentage to convert total production employment to total 
domestic production employment. The U.S. labor percentage represents 
the industry fraction of domestic manufacturing production capacity for 
the covered product. This value is derived from manufacturer 
interviews, product database analysis, and publicly available 
information. Consistent with the February 2023 NOPR, DOE estimates that 
28 percent of refrigerators, refrigerator-freezers, and freezers are 
produced domestically.
    The domestic production employees estimate covers production line 
workers, including line supervisors, who are directly involved in 
fabricating and assembling products within the OEM facility. Workers 
performing services that are closely associated with production 
operations, such as materials-handling tasks using forklifts, are also 
included as production labor. DOE's estimates only account for 
production workers who manufacture the specific products covered by 
this rulemaking.
    Non-production workers account for the remainder of the direct 
employment figure. The non-production employees estimate covers 
domestic workers who are not directly involved in the production 
process, such as sales, engineering, human resources, and 
management.\100\ Using the amount of domestic production workers 
calculated above, non-production domestic employees are extrapolated by 
multiplying the ratio of non-production workers in the industry 
compared to production employees. DOE assumes that this employee 
distribution ratio remains constant between the no-new-standards case 
and standards cases.
---------------------------------------------------------------------------

    \100\ The comprehensive description of production and non-
production workers is available at ``Definitions and Instructions 
for the Annual Survey of Manufacturers, MA-10000'' (pp. 13-14)

accessed September 9, 2023).
---------------------------------------------------------------------------

    Using the GRIM, DOE estimates in the absence of new energy 
conservation standards there would be 6,366 domestic production and 
non-production workers for refrigerators, refrigerator-freezers, and 
freezers in 2027. Table V.27 shows the range of the impacts of energy 
conservation standards on U.S. manufacturing employment in the 
refrigerator, refrigerator-freezer, and freezer industry. The following 
discussion provides a qualitative evaluation of the range of potential 
impacts presented in Table V.27.

--------------------------------------------------------------------------------------------------------------------------------------------------------
* For TSL 4 (the Recommended TSL), the direct employment values reflect 2030 estimates.
** DOE presents a range of potential employment impacts. Numbers in parentheses denote negative values.

    The direct employment impacts shown in Table V.27 represent the 
potential domestic employment changes that could result following the 
compliance date for the refrigerator, refrigerator-freezer, and freezer 
product classes in this direct final rule. The upper bound estimate 
corresponds to an increase in the number of domestic workers that would 
result from amended energy conservation standards if manufacturers 
continue to produce the same scope of covered products within the 
United States after compliance takes effect. The lower bound estimate 
represents the maximum decrease in production workers if manufacturing 
moved to lower labor-cost countries. Most manufacturers currently 
produce at least a portion of their refrigerators, refrigerator-
freezers, and freezers in countries with lower labor costs. Adopting an 
amended standard that necessitates large increases in labor content or 
large expenditures to re-tool facilities could cause manufacturers to 
reevaluate domestic production siting options. At the Recommended TSL 
(TSL 4), DOE expects some manufacturers would need to implement 
insulation changes (e.g., VIPs and/or increasing wall thickness) into 
certain product classes, which could require additional labor content 
and capital investment. For the high-volume product classes, DOE 
expects that PC 5A and some PC 5 models \101\ would likely require 
implementing partial VIPs to meet TSL 4 efficiencies. DOE estimates the 
products that would likely require some VIPs to meet TSL 4 efficiencies 
collectively account for approximately 24 percent of industry 
shipments. Based on information gathered during confidential 
manufacturer interviews and public sources, DOE understands that a 
portion of PC 5 and PC 5A products are currently manufactured in the 
United States. Although it is possible that amended standards in this 
rulemaking and other DOE rulemakings could factor into production 
siting locations due to the level of investment and additional labor 
content required. However, based on information gathered during 
confidential manufacturer interviews, DOE does not expect most 
manufacturers would shift domestic production outside of the United 
States solely as a result of this direct final rule.
---------------------------------------------------------------------------

    \101\ The design path analyzed in DOE's engineering analysis for 
PC 5 with a 3-door configuration (adjusted volume of 30 ft\3\) would 
likely require some VIPs at TSL 4 (EL 2). See section IV.C.2 of this 
document for the analyzed design options at each efficiency level 
for the directly analyzed product classes.
---------------------------------------------------------------------------

    Additional detail on the analysis of direct employment can be found 
in chapter 12 of the direct final rule TSD. Additionally, the 
employment impacts discussed in this section are independent of the 
employment impacts from the broader U.S. economy, which are documented 
in chapter 16 of the direct final rule TSD.
c. Impacts on Manufacturing Capacity
    In interviews, some manufacturers noted potential capacity concerns 
related to implementing VIPs, particularly for high-volume product 
lines (i.e., PC 3, PC 5, PC 5A, and PC 7). These manufacturers noted 
that incorporating VIPs (or additional VIPs) is labor intensive. 
Implementing VIPs requires additional labor associated with initial 
quality control inspections, placement, and post-foam inspections. 
These manufacturers noted they are physically constrained at some 
factories and do not have the ability to extend production lines to 
accommodate additional labor content. As discussed in section V.B.2.a 
of this document, some manufacturers noted that the only way to 
maintain current production levels would be to expand the existing 
footprint, build a mezzanine, or move to a new production facility. In 
interviews, some manufacturers expressed concerns at the max-tech 
efficiencies for top-mount (TSL 6), bottom-mount with through-the-door 
ice service (TSL 5), bottom-mount without through-the-door ice service 
(TSL 6), and side-by-side (TSL 6) standard-size refrigerator-freezers, 
and stated that the 3-year period between the announcement of the 
direct final rule and the compliance date of the amended energy 
conservation standard might be insufficient to update existing plants 
or build new facilities to accommodate the additional labor required to 
manufacture the necessary number of products to meet demand. In this 
direct final rule, DOE adopts TSL 4 (the Recommended TSL). At the 
adopted level, the max-tech efficiencies are not required for any of 
the analyzed product classes, including the high-volume product classes 
manufacturers expressed concerns about during confidential interviews. 
Furthermore, compliance with amended standards would not be required 
until 2030 for freestanding top-mount product classes (i.e., PC 1, PC 
1A, PC 2, PC 3, PC 3A, PC 6), freestanding side-by-side product classes 
(i.e., PC 4, PC 7), and freestanding bottom-mount without through-the-
door ice service product class (i.e., PC 5), and 2029 for the remaining 
product classes. Compared to TSLs with a 2027 compliance date, 
manufacturers would have additional time to update production 
facilities and redesign products to meet amended standards. The 
Recommended TSL's compliance dates would provide manufacturers the 
opportunity to spread capital requirements, engineering resources, and 
conversion activities over a longer period of time.
    In response to the February 2023 NOPR, AHAM, Whirlpool, GEA, and 
Sub Zero expressed concerns that the supply of high-efficiency 
components such as VIPs and VSCs would not be able to ramp up in the 3-
year compliance period to meet the expected consumer demand for 
refrigerators, refrigerator-freezers, and freezers. (AHAM, No. 69 at p. 
5; Whirlpool, No. 70 at p. 5; GEA, No. 75 at p. 2; and Sub Zero, No. 77 
at p. 2) Conversely, Samsung commented that the industry has a 
significant amount of VSCs available for purchase, and that the 3-year 
compliance period is acceptable for manufacturers and suppliers to 
establish sufficient availability of VSCs. (Samsung, No. 78 at p. 3)
    In support of this analysis, DOE conducted research and interviewed

[[Page 3091]]

VSC and VIP component suppliers to gather additional information on the 
global market capacity for these high-efficiency components. Based on 
the information gathered, DOE expects that VIP production lines can be 
quickly scaled up to meet demand of future amended standards (within 1 
to 2 years depending on the specific VIP design). For VSCs, based on 
supplier information on the global refrigerator VSC production 
capacity, supply constraints, and ramp-up time, DOE determined that the 
industry can meet the increased demand of VSCs that may result due to 
the adoption of more stringent standards within the necessary 
compliance period, with an estimated 8 to 12 month VSC production ramp-
up, as needed.
d. Impacts on Subgroups of Manufacturers
    Using average cost assumptions to develop industry cash flow 
estimates may not capture the differential impacts among subgroups of 
manufacturers. Small manufacturers, niche players, or manufacturers 
exhibiting a cost structure that differs substantially from the 
industry average could be affected disproportionately. DOE investigated 
small businesses as a manufacturer subgroup that could be 
disproportionally impacted by energy conservation standards and could 
merit additional analysis. DOE also identified the domestic LVM 
subgroup as a potential manufacturer subgroup that could be adversely 
impacted by energy conservation standards based on the results of the 
industry characterization.
Small Businesses
    DOE analyzes the impacts on small businesses in a separate analysis 
for the standards proposed in the NOPR published elsewhere in this 
issue of the Federal Register and in chapter 12 of the direct final 
rule TSD. In summary, the Small Business Administration (``SBA'') 
defines a ``small business'' as having 1,500 employees or less for 
NAICS 335220, ``Major Household Appliance Manufacturing.'' Based on 
this classification, DOE identified one domestic OEM that qualifies as 
a small business. For a discussion of the impacts on the small business 
manufacturer subgroup, see chapter 12 of the direct final rule TSD.
Domestic, Low-Volume Manufacturers
    In addition to the small business subgroup, DOE identified domestic 
LVMs as a manufacturer subgroup that may experience differential 
impacts due to amended standards. DOE identified three domestic LVMs of 
refrigerators, refrigerator-freezers, and freezers that would 
potentially face more challenges with meeting amended standards than 
other larger OEMs of the covered products.
    Although these LVMs do not qualify as small businesses according to 
the SBA criteria previously discussed (i.e., employee count exceeds 
1,500), these manufacturers are significantly smaller in terms of 
annual revenues than the larger, diversified manufacturers selling 
refrigerators, refrigerator-freezers, and freezers in the United 
States. The domestic LVM subgroup consists of refrigerator, 
refrigerator-freezer, and freezer manufacturers that primarily sell 
high-end, built-in or fully integrated consumer refrigeration products 
(``undercounter'' and standard-size) as well as miscellaneous 
refrigeration products, commercial refrigeration equipment, and cooking 
products. Specifically, manufacturers indicated during confidential 
interviews that the fully integrated compact (``undercounter'') 
products produced by the domestic LVMs are niche products and are more 
expensive to produce (and, therefore, have higher selling prices) than 
the majority of the compact products sold in the United States.
    Table V.28 lists the range of product offerings and estimated total 
company annual revenue for the three domestic LVMs identified. These 
three manufacturers account for approximately 1 percent of the overall 
domestic refrigerator, refrigerator-freezer, and freezer shipments. 
This table also contains the range of total company annual revenue for 
the five largest appliance manufacturers selling refrigerators, 
refrigerator-freezers, and freezers in the U.S. market. These five 
appliance manufacturers account for approximately 95 percent of the 
overall domestic refrigerator, refrigerator-freezer, and freezer 
shipments.

* Revenue estimates refer to the total annual company revenue of the

    LVMs may be disproportionately affected by conversion costs. 
Product redesign, testing, and certification costs tend to be fixed per 
basic model and do not scale with sales volume. Both large 
manufacturers and LVMs must make investments in R&D to redesign their 
products, but LVMs lack the sales volumes to sufficiently recoup these 
upfront investments without substantially marking up their products' 
selling prices. LVMs may also face challenges related to purchasing 
power and a less robust supply chain for key technologies or 
components, as compared to larger manufacturers. DOE notes that 
domestic LVMs have access to the same technology options as larger 
appliance manufacturers, the challenge with redesigning products to 
meet amended standards relates to scale and their ability to recover 
investments necessitated by more stringent standards.
    Although domestic, low-volume manufacturers would likely face 
additional challenges meeting amended standards for the built-in and 
compact (``undercounter'') refrigerator, refrigerator-freezer, and 
freezer product classes compared to other refrigerator, refrigerator-
freezer, and freezer manufacturers, some of the adopted amendments may 
be beneficial for domestic LVMs. As discussed in section IV.A.1 of this 
document, DOE is proposing to incorporate certain energy use allowances 
for products with special doors and multi-door designs. A review of the 
three domestic LVM's product offerings and information gathered in 
confidential interviews

[[Page 3092]]

indicates transparent door designs are particularly prevalent in their 
products. See section IV.A.1 of this document for additional details on 
energy use allowances for products with special doors and multi-door 
designs.
e. Cumulative Regulatory Burden
    One aspect of assessing manufacturer burden involves looking at the 
cumulative impact of multiple DOE standards and the regulatory actions 
of other Federal agencies and States that affect the manufacturers of a 
covered product or equipment. While any one regulation may not impose a 
significant burden on manufacturers, the combined effects of several 
existing or impending regulations may have serious consequences for 
some manufacturers, groups of manufacturers, or an entire industry. 
Multiple regulations affecting the same manufacturer can strain profits 
and lead companies to abandon product lines or markets with lower 
expected future returns than competing products. For these reasons, DOE 
conducts an analysis of cumulative regulatory burden as part of its 
rulemakings pertaining to appliance efficiency.
    For the cumulative regulatory burden analysis, DOE examines 
Federal, product-specific regulations that could affect refrigerator, 
refrigerator-freezer, and freezer manufacturers that take effect 
approximately 3 years before the 2029 compliance date and 3 years after 
the after the 2030 compliance date (2026 to 2033). This information is 
presented in Table V.29.

* This column presents the total number of OEMs identified in the energy conservation standard rule that is
  contributing to cumulative regulatory burden.
** This column presents the number of OEMs producing refrigerators, refrigerator-freezers, and freezers that are
  also listed as OEMs in the identified energy conservation standard that is contributing to cumulative
  regulatory burden.
*** This column presents industry conversion costs as a percentage of equipment revenue during the conversion
  period. Industry conversion costs are the upfront investments manufacturers must make to sell compliant
  products/equipment. The revenue used for this calculation is the revenue from just the covered product/
  equipment associated with each row. The conversion period is the time frame over which conversion costs are
  made and lasts from the publication year of the final rule to the compliance year of the energy conservation
  standard. The conversion period typically ranges from 3 to 5 years, depending on the rulemaking.
[dagger] These rulemakings are at the NOPR stage, and all values are subject to change until finalized through
  publication of a final rule.
[Dagger] At the time of issuance of this refrigerator, refrigerator-freezer, and freezer direct final rule, the
  consumer furnace final rule has been issued and is pending publication in the Federal Register. Once
  published, the final rule pertaining to gas-fired consumer furnaces will be available at: www.regulations.gov/docket/EERE-2014-BT-STD-0031/document.

    As shown in Table V.29, the ongoing rulemakings with the largest 
overlap of refrigerator, refrigerator-freezer, and freezer OEMs include 
miscellaneous refrigeration products, consumer conventional cooking 
products, residential clothes washers, consumer clothes dryers, and 
dishwashers, which are all part of the multi-product Joint Agreement 
submitted by interested parties. As detailed in the multi-product Joint 
Agreement, the signatories indicated that their recommendations should 
be considered a ``complete package.'' The signatories further stated 
that ``each part of this agreement is contingent upon the other parts 
being implemented.'' (Joint Agreement, No. 103 at p. 3)
    The multi-product Joint Agreement states the ``jointly recommended

[[Page 3093]]

compliance dates will achieve the overall energy and economic benefits 
of this agreement while allowing necessary lead-times for manufacturers 
to redesign products and retool manufacturing plants to meet the 
recommended standards across product categories.'' (Joint Agreement, 
No. 103 at p. 2) The staggered compliance dates help mitigate 
manufacturers' concerns about their ability to allocate sufficient 
resources to comply with multiple concurrent amended standards and 
about the need to align compliance dates for products that are 
typically designed or sold as matched pairs (such as RCWs and consumer 
clothes dryers). See section IV.J.3 of this document for stakeholder 
comments about cumulative regulatory burden. See Table V.30 for a 
comparison of the estimated compliance dates based on EPCA-specified 
timelines and the compliance dates detailed in the Joint Agreement.

3. National Impact Analysis
    This section presents DOE's estimates of the national energy 
savings and the NPV of consumer benefits that would result from each of 
the TSLs considered as potential amended standards.
a. Significance of Energy Savings
    To estimate the energy savings attributable to potential amended 
standards for refrigerators, refrigerator-freezers, and freezers, DOE 
compared their energy consumption under the no-new-standards case to 
their anticipated energy consumption under each TSL. The savings are 
measured over the entire lifetime of products purchased in the 30-year 
period that begins in the year of anticipated compliance with amended 
standards (2027-2056 for all TSLs other than TSL 4; for TSL 4, 2029-
2058 for the product classes listed in Table I.1 and 2030-2059 for the 
product classes listed in Table I.2). Tables V.30 and V.31 present 
DOE's projections of the national energy savings for each TSL 
considered for refrigerators, refrigerator-freezers, and freezers. The 
savings were calculated using the approach described in section IV.H.2 
of this document.

    OMB Circular A-4 \102\ requires agencies to present analytical 
results, including separate schedules of the monetized benefits and 
costs that show the type and timing of benefits and costs. Circular A-4 
also directs agencies to consider the variability of key elements 
underlying the estimates of benefits and costs. For this rulemaking, 
DOE undertook a sensitivity analysis using 9 years, rather than 30 
years, of product shipments. The choice of a 9-year period is a proxy 
for the timeline in EPCA for the review of certain energy conservation 
standards and potential revision of and compliance with such revised 
standards.\103\ The review timeframe established in EPCA is generally 
not synchronized with the product lifetime, product manufacturing 
cycles, or other factors specific to refrigerators, refrigerator-
freezers, and freezers. Thus, such results are presented for 
informational purposes only and are not indicative of any change in 
DOE's analytical methodology. The NES sensitivity analysis results 
based on a 9-year analytical period are presented in Tables V.32 and 
V.33. The impacts are counted over the lifetime of refrigerators, 
refrigerator-freezers, and freezers purchased 2027-2035 for all TSLs

    \102\ U.S. Office of Management and Budget. Circular A-4: 
Regulatory Analysis. Available at https://www.whitehouse.gov/omb/information-for-agencies/circulars/ (last accessed July 13, 2023). 
DOE used the prior version of Circular A-4 (2003) as a result of the 
effective date of the new version.
    \103\ EPCA requires DOE to review its standards at least once 
every 6 years, and requires, for certain products, a 3-year period 
after any new standard is promulgated before compliance is required, 
except that in no case may any new standards be required within 6 
years of the compliance date of the previous standards. While adding 
a 6-year review to the 3-year compliance period adds up to 9 years, 
DOE notes that it may undertake reviews at any time within the 6-
year period and that the 3-year compliance date may yield to the 6-
year backstop. A 9-year analysis period may not be appropriate given 
the variability that occurs in the timing of standards reviews and 
the fact that for some products, the compliance period is 5 years 
rather than 3 years.

    DOE estimated the cumulative NPV of the total costs and savings for 
consumers that would result from the TSLs considered for refrigerators, 
refrigerator-freezers, and freezers. In accordance with OMB's 
guidelines on regulatory analysis,\104\ DOE calculated NPV using both a 
7-percent and a 3-percent real discount rate. Tables V.34 and V.35 show 
the consumer NPV results with impacts counted over the lifetime of 
products purchased in 2027-2056 for all TSLs except TSL 4; for TSL 4, 
2029-2058 for the product classes listed in Table I.1 and 2030-2059 for 
the product classes listed in Table I.2.

    The previous results reflect the use of a default trend to estimate 
the change in price for refrigerators, refrigerator-freezers, and 
freezers over the analysis period (see section IV.H.3 of this 
document). DOE also conducted a sensitivity analysis that considered 
one scenario with a lower rate of price decline than the reference case 
and one scenario with a higher rate of price decline than the reference 
case. The results of these alternative cases are presented in appendix 
10C of the direct final rule TSD. In the high-price-decline case, the 
NPV of consumer benefits is higher than in the default case. In the 
low-price-decline case, the NPV of consumer benefits is lower than in 
the default case.
c. Indirect Impacts on Employment
    DOE estimates that amended energy conservation standards for 
refrigerators, refrigerator-freezers, and freezers will reduce energy 
expenditures for consumers of those products, with the resulting net 
savings being redirected to other forms of economic activity. These 
expected shifts in spending and economic activity could affect the 
demand for labor. As described in section IV.N of this document, DOE 
used an input/output model of the U.S. economy to estimate indirect 
employment impacts of the TSLs that DOE considered. There are 
uncertainties involved in projecting employment impacts, especially 
changes in the later years of the analysis. Therefore, DOE generated 
results for near-term timeframes (2029/30-2033/34), where these 
uncertainties are reduced.
    The results suggest that the adopted standards are likely to have a 
negligible impact on the net demand for labor in the economy. The net 
change in jobs is so small that it would be imperceptible in national 
labor statistics and might be offset by other, unanticipated effects on 
employment. Chapter 16 of the direct final rule TSD presents detailed 
results regarding anticipated indirect employment impacts.
4. Impact on Utility or Performance of Products
    As discussed in section III.F.1.d of this document, DOE has 
concluded that the standards adopted in this direct final rule will not 
lessen the utility or performance of the refrigerators, refrigerator-
freezers, and freezers under consideration in this rulemaking. 
Manufacturers of these products currently offer units that meet or 
exceed the adopted standards.
5. Impact of Any Lessening of Competition
    DOE considered any lessening of competition that would be likely to 
result from new or amended standards. As discussed in section 
III.F.1.e, EPCA directs the Attorney General of the United States 
(``Attorney General'') to determine the impact, if any, of any 
lessening of competition likely to result from a proposed standard and 
to transmit such determination in writing to the Secretary within 60 
days of the publication of a proposed rule, together with an analysis 
of the nature and extent of the impact. To assist the Attorney General 
in making this determination, DOE is providing DOJ with copies of this 
direct final rule and the TSD for review.
6. Need of the Nation To Conserve Energy
    Enhanced energy efficiency, where economically justified, improves 
the Nation's energy security, strengthens the economy, and reduces the 
environmental impacts (costs) of energy production. Reduced electricity 
demand due to energy conservation standards is also likely to reduce 
the cost of maintaining the reliability of the electricity system, 
particularly during peak-load periods. Chapter 15 in the direct final 
rule TSD presents the estimated impacts on electricity generating 
capacity, relative to the no-new-standards case, for the TSLs that DOE 
considered in this rulemaking.
    Energy conservation resulting from potential energy conservation 
standards for refrigerators, refrigerator-freezers, and freezers is 
expected to yield environmental benefits in the form of reduced 
emissions of certain air pollutants and greenhouse gases. Table V.38 
provides DOE's estimate of cumulative emissions reductions expected to 
result from the TSLs considered in this rulemaking. The emissions were 
calculated using the multipliers discussed in section IV.K. DOE reports 
annual emissions reductions for each TSL in chapter 13 of the direct 
final rule TSD.

    DOE is well aware that scientific and economic knowledge about the 
contribution of CO<INF>2</INF> and other GHG emissions to changes in 
the future global climate and the potential resulting damages to the 
global and U.S. economy continues to evolve rapidly. DOE, together with 
other Federal agencies, will continue to review methodologies for 
estimating the monetary value of reductions in CO<INF>2</INF> and other 
GHG emissions. This ongoing review will consider the comments on this 
subject that are part of the public record for this and other 
rulemakings, as well as other methodological assumptions and issues. 
DOE notes, however, that the adopted standards would be economically 
justified even without inclusion of monetized benefits of reduced GHG 
emissions.
    DOE also estimated the monetary value of the economic benefits 
associated with NO<INF>X</INF> and SO<INF>2</INF> emissions reductions 
anticipated to result from the considered TSLs for refrigerators, 
refrigerator-freezers, and freezers. The dollar-per-ton values that DOE 
used are discussed in section IV.L of this document. Table V.42 
presents the present value for NO<INF>X</INF> emissions reduction for 
each TSL calculated using 7-percent and 3-percent discount rates, and 
Table V.43 presents similar results for SO<INF>2</INF> emissions 
reductions. The results in these tables reflect application of EPA's 
low dollar-per-ton values, which DOE used to be conservative. The time-
series of annual values is presented for the selected TSL in chapter 14 
of the direct final rule TSD.

    Not all the public health and environmental benefits from the 
reduction of greenhouse gases, NO<INF>X</INF>, and SO<INF>2</INF> are 
captured in the values above, and additional unquantified benefits from 
the reductions of those pollutants as well as from the reduction of 
direct PM and other co-pollutants may be significant. DOE has not 
included monetary benefits of the reduction of Hg emissions because the 
amount of reduction is very small.
7. Other Factors
    The Secretary of Energy, in determining whether a standard is 
economically justified, may consider any other factors that the 
Secretary deems to be relevant. (42 U.S.C. 6295(o)(2)(B)(i)(VII)) No 
other factors were considered in this analysis.
8. Summary of Economic Impacts
    Table V.44 presents the NPV values that result from adding the 
estimates of the economic benefits resulting from reduced GHG and 
NO<INF>X</INF> and SO<INF>2</INF> emissions to the NPV of consumer 
benefits calculated for each TSL considered in this rulemaking. The 
consumer benefits are domestic U.S. monetary savings that occur as a 
result of purchasing the covered refrigerators, refrigerator-freezers, 
and freezers, and are measured for the lifetime of products shipped in 
2027-2056 for all TSLs except TSL 4; for TSL 4, 2029-2058 for the 
product classes listed in Table I.1 and 2030-2059 for the product 
classes listed in Table I.2.
    The climate benefits associated with reduced GHG emissions 
resulting from the adopted standards are global benefits, and are also 
calculated based on the lifetime of refrigerators, refrigerator-
freezers, and freezers shipped during the period 2027-2056 for all TSLs 
except TSL 4; for TSL 4, 2029-2058 for the product classes listed in 
Table I.1 and 2030-2059 for the product classes listed in Table I.2.

C. Conclusion

    When considering new or amended energy conservation standards, the 
standards that DOE adopts for any type (or class) of covered product 
must be designed to achieve the maximum improvement in energy 
efficiency that the Secretary determines is technologically feasible 
and economically justified. (42 U.S.C. 6295(o)(2)(A)) In determining 
whether a standard is economically justified, the Secretary must 
determine whether the benefits of the standard exceed its burdens by, 
to the greatest extent practicable, considering the seven statutory 
factors discussed previously. (42 U.S.C. 6295(o)(2)(B)(i)) The new or 
amended standard must also result in significant conservation of 
energy. (42 U.S.C. 6295(o)(3)(B))
    For this direct final rule, DOE considered the impacts of amended 
standards for refrigerators, refrigerator-freezers, and freezers at 
each TSL, beginning with the maximum technologically feasible level, to 
determine whether that level was economically justified. Where the max-
tech level was not justified, DOE then considered the next most 
efficient level and undertook the same evaluation until it reached the 
highest efficiency level that is both technologically feasible and 
economically justified and saves a significant amount of energy.
    To aid the reader as DOE discusses the benefits and/or burdens of 
each TSL, tables in this section present a summary of the results of 
DOE's quantitative analysis for each TSL. In addition to the 
quantitative results presented in the tables, DOE also considers other 
burdens and benefits that affect economic justification. These include 
the impacts on identifiable subgroups of consumers who may be

[[Page 3101]]

disproportionately affected by a national standard and impacts on 
employment.
    DOE also notes that the economics literature provides a wide-
ranging discussion of how consumers trade off upfront costs and energy 
savings in the absence of government intervention. Much of this 
literature attempts to explain why consumers appear to undervalue 
energy efficiency improvements. There is evidence that consumers 
undervalue future energy savings as a result of (1) a lack of 
information; (2) a lack of sufficient salience of the long-term or 
aggregate benefits; (3) a lack of sufficient savings to warrant 
delaying or altering purchases; (4) excessive focus on the short term, 
in the form of inconsistent weighting of future energy cost savings 
relative to available returns on other investments; (5) computational 
or other difficulties associated with the evaluation of relevant 
tradeoffs; and (6) a divergence in incentives (for example, between 
renters and owners, or builders and purchasers). Having less than 
perfect foresight and a high degree of uncertainty about the future, 
consumers may trade off these types of investments at a higher-than-
expected rate between current consumption and uncertain future energy 
cost savings.
    In DOE's current regulatory analysis, potential changes in the 
benefits and costs of a regulation due to changes in consumer purchase 
decisions are included in two ways. First, if consumers forego the 
purchase of a product in the standards case, this decreases sales for 
product manufacturers, and the impact on manufacturers attributed to 
lost revenue is included in the MIA. Second, DOE accounts for energy 
savings attributable only to products actually used by consumers in the 
standards case; if a standard decreases the number of products 
purchased by consumers, this decreases the potential energy savings 
from an energy conservation standard. DOE provides estimates of 
shipments and changes in the volume of product purchases in chapter 9 
of the direct final rule TSD. However, DOE's current analysis does not 
explicitly control for heterogeneity in consumer preferences, 
preferences across subcategories of products or specific features, or 
consumer price sensitivity variation according to household 
income.\105\

---------------------------------------------------------------------------

    While DOE is not prepared at present to provide a fuller 
quantifiable framework for estimating the benefits and costs of changes 
in consumer purchase decisions due to an energy conservation standard, 
DOE is committed to developing a framework that can support empirical 
quantitative tools for improved assessment of the consumer welfare 
impacts of appliance standards. DOE has posted a paper that discusses 
the issue of consumer welfare impacts of appliance energy conservation 
standards, and potential enhancements to the methodology by which these 
impacts are defined and estimated in the regulatory process.\106\ DOE 
welcomes comments on how to more fully assess the potential impact of 
energy conservation standards on consumer choice and how to quantify 
this impact in its regulatory analysis in future rulemakings.

1. Benefits and Burdens of TSLs Considered for Refrigerator, 
Refrigerator-Freezer, and Freezer Standards
    Tables V.46 and V.47 summarize the quantitative impacts estimated 
for each TSL for refrigerators, refrigerator-freezers, and freezers. 
The national impacts are measured over the lifetime of refrigerators, 
refrigerator-freezers, and freezers purchased in the 30-year period 
that begins in the anticipated year of compliance with amended 
standards (2027-2056 for all TSLs except TSL 4; for TSL 4, 2029-2058 
for the product classes listed in Table I.1 and 2030-2059 for the 
product classes listed in Table I.2). The energy savings, emissions 
reductions, and value of emissions reductions refer to full-fuel-cycle 
results. DOE is presenting monetized benefits of GHG emissions 
reductions in accordance with the applicable Executive orders and DOE 
would reach the same conclusion presented in this direct final rule in 
the absence of the social cost of greenhouse gases, including the 
Interim Estimates presented by the Interagency Working Group. The 
efficiency levels contained in each TSL are described in section V.A of 
this document.

Note: This table presents the costs and benefits associated with consumer refrigerators, refrigerator-freezers, and freezers shipped in 2027-2056 for
  all TSLs except TSL 4; for TSL 4, 2029-2058 for the product classes listed in Table I.1 and 2030-2059 for the product classes listed in Table I.2.
  These results include benefits to consumers which accrue after 2056 from the products shipped in 2027-2056 for all TSLs except TSL 4; for TSL 4, 2029-
  2058 for the product classes listed in Table I.1 and 2030-2059 for the product classes listed in Table I.2.
* Climate benefits are calculated using four different estimates of the SC-CO2, SC-CH4, and SC-N2O. Together, these represent the global SC-GHG. For
  presentational purposes of this table, the climate benefits associated with the average SC-GHG at a 3-percent discount rate are shown; however, DOE
  emphasizes the importance and value of considering the benefits calculated using all four sets of SC-GHG estimates. To monetize the benefits of
  reducing GHG emissions, this analysis uses the interim estimates presented in the Technical Support Document: Social Cost of Carbon, Methane, and
  Nitrous Oxide Interim Estimates Under Executive Order 13990 published in February 2021 by the IWG.
** Health benefits are calculated using benefit-per-ton values for NOX and SO2. DOE is currently only monetizing (for NOX and SO2) PM2.5 precursor
  health benefits and (for NOX) ozone precursor health benefits, but will continue to assess the ability to monetize other effects such as health
  benefits from reductions in direct PM2.5 emissions. The health benefits are presented at real discount rates of 3 and 7 percent. See section IV.L of
  this document for more details.
[dagger] Total and net benefits include consumer, climate, and health benefits. For presentation purposes, total and net benefits for both the 3-percent
  and 7-percent cases are presented using the average SC-GHG with 3-percent discount rate.

Parentheses indicate negative (-) values. The entry ``N/A'' means not applicable because there is no change in the standard at certain TSLs.
* Weighted by shares of each product class in total projected shipments in 2027 for all TSLs except TSL 4; for TSL 4, 2029 for PCs 5BI, 5A, 10, 11A, 17,
  and 18, and 2030 for PCs 3, 5, 7, and 9.

    DOE first considered TSL 6, which represents the max-tech 
efficiency levels. At this level, DOE expects that all product classes 
would require VIPs and most would require VSCs. For most product 
classes, this represents the use of VIPs for roughly half the cabinet 
surface (typically side walls and doors for an upright cabinet), the 
best-available-efficiency variable-speed compressor, forced-convection 
heat exchangers with multi-speed BLDC fans, variable defrost, and 
increase in cabinet wall thickness for some classes (e.g., compact 
refrigerators and both standard-size and compact chest freezers). DOE 
estimates that less than 1 percent of annual shipments across all 
refrigerator, refrigerator-freezer, and freezer product classes 
currently meet the max-tech efficiencies required. TSL 6 would save an 
estimated 9.57 quads of energy, an amount DOE considers significant. 
Under TSL 6, the NPV of consumer benefit would be $5.23 billion using a 
discount rate of 7 percent, and $25.42 billion using a discount rate of 
3 percent.
    The cumulative emissions reductions at TSL 6 are 176 Mt of 
CO<INF>2</INF>, 55.5 thousand tons of SO<INF>2</INF>, 323 thousand tons 
of NO<INF>X</INF>, 0.38 tons of Hg, 1,455 thousand tons of 
CH<INF>4</INF>, and 1.75 thousand tons of N<INF>2</INF>O. The estimated 
monetary value of the climate benefits from reduced GHG emissions 
(associated with the average SC-GHG at a 3-percent discount rate) at 
TSL 6 is $9.29 billion. The estimated monetary value of the health 
benefits from reduced SO<INF>2</INF> and NO<INF>X</INF> emissions at 
TSL 6 is $7.12 billion using a 7-percent discount rate and $18.24 
billion using a 3-percent discount rate.
    Using a 7-percent discount rate for consumer benefits and costs, 
health benefits from reduced SO<INF>2</INF> and NO<INF>X</INF> 
emissions, and the 3-percent discount rate case for climate benefits 
from reduced GHG emissions, the estimated total NPV at TSL 6 is $21.64 
billion. Using a 3-percent discount rate for all benefits and costs, 
the estimated total NPV at TSL 6 is $52.96 billion. The estimated total 
NPV is provided for additional information, however DOE primarily 
relies upon the NPV of consumer benefits when determining whether a 
standard level is economically justified.
    At TSL 6, for the largest product classes, which are 3, 5, 5A, and 
7 and together account for approximately 76 percent of annual 
shipments, there is a life-cycle cost savings of $0.03, $20.22, 
$122.18, and $69.71 and a payback period of 9.3 years, 8.6 years, 6.0 
years and 6.8 years, respectively. However, for these product classes, 
the fraction of customers experiencing a net LCC cost is 67.1 percent, 
60.3 percent, 39.4 percent and 48.3 percent with increases in first 
cost of $169.37, $151.75, $161.65, and $153.01, respectively. Overall, 
a majority of refrigerators, refrigerator-freezers, and freezers 
consumers (60 percent) would experience a net cost and the average LCC 
savings would be negative for PC 5BI, PC 10, PC 11A, and PC 18. 
Additionally, 35 percent of low-income households with a side-by-side 
refrigerator-freezer (represented by PC 7 and used by 19 percent of 
low-income households) would experience a net cost.
    At TSL 6, the projected change in INPV ranges from a decrease of 
$1.83 billion to a decrease of $1.30 billion, which corresponds to 
decreases of 37.2 percent and 26.5 percent, respectively. Industry 
conversion costs could reach $2.39 billion as manufacturers work to 
redesign their portfolio of model offerings and re-tool entire 
factories to comply with amended standards at TSL 6.
    DOE estimates that less than 1 percent of refrigerator, 
refrigerator-freezer, and freezer current annual shipments meet the 
max-tech levels. At TSL 6, only a few manufacturers offer any standard-
size products that meet the efficiencies required. For PC 3, which 
accounts for approximately 25 percent of annual shipments, no OEMs 
currently offer products that meet the efficiency level required. For 
PC 5, which accounts for approximately 21 percent of annual shipments, 
DOE estimates that seven out of 22 OEMs currently offer products that 
meet the efficiency level required. For PC 7, which accounts for 
approximately 11 percent of annual shipments, only one out of 11 OEMs 
currently offers products that meet the efficiency level required.
    At max-tech, manufacturers would likely need to implement all the 
most efficient design options in the engineering analysis. In 
interviews, manufacturer indicated they would redesign all product 
platforms and dramatically update manufacturing facilities to meet max-
tech for all approximately 17.0 million annual shipments of 
refrigerators, refrigerator-freezers, and freezers.\107\
---------------------------------------------------------------------------

    \107\ Current shipments calculations relied on shipments in the 
year 2023.
---------------------------------------------------------------------------

    In particular, increased incorporation of VIPs could increase the 
expense of adapting manufacturing plants. As discussed in section 
IV.J.2.c of this document, DOE expects manufacturers would likely adopt 
VIP technology to improve thermal insulation while minimizing loss to 
the interior volume for their products. Extensive incorporation of VIPs 
requires significant capital expenditures due to the need for more 
careful product handling and conveyor, increased warehousing 
requirements, investments in tooling necessary for the VIP installation 
process, and adding production line capacity to compensate for more 
time-intensive manufacturing associated with VIPs. Manufacturers with 
facilities that have limited space and few options to expand may 
consider greenfield projects. In interviews, several manufacturers 
expressed concerns about their ability to produce sufficient quantities 
of refrigerators, refrigerator-freezers, and freezers at max-tech given 
the required scale of investment, redesign effort, and 3-year 
compliance timeline.

    The Secretary concludes that at TSL 6 for refrigerators, 
refrigerator-freezers, and freezers, the benefits of energy savings, 
positive NPV of consumer benefits, emission reductions, and the 
estimated monetary value of the emissions reductions would be 
outweighed by the economic burden on many consumers, and the impacts on 
manufacturers, including the large potential reduction in INPV and the 
lack of manufacturers currently offering products meeting the 
efficiency levels required at this TSL. At TSL 6, a majority of 
refrigerator, refrigerator-freezer, and freezers consumers (60 percent) 
would experience a net cost and the average LCC savings would be 
negative for PC 5BI, PC 10, PC 11A, and PC 18. Additionally, 
manufacturers would need to make significant upfront investments to 
update product lines and manufacturing facilities. Manufacturers 
expressed concern that they would not be able to complete product and 
production line updates within the 3-year conversion period. 
Consequently, the Secretary has concluded that TSL 6 is not 
economically justified.
    DOE then considered TSL 5 for refrigerators, refrigerator-freezers, 
and freezers. For classes other than refrigerator-freezers with bottom-
mounted freezers and through-the-door ice service (PC 5A), this TSL 
represents efficiency levels less than max-tech. TSL 5 represents 
similar design options as max-tech, but generally incorporates the use 
of high-efficiency compressors (single speed compressors or VSCs) 
rather than maximum efficiency VSCs, incorporates VIPs in fewer product 
classes, and incorporates less VIP surface area for the product classes 
requiring the use of VIPs as compared to TSL 6. TSL 5 would save an 
estimated 6.01 quads of energy, an amount DOE considers significant. 
Under TSL 5, the NPV of consumer benefit would be $8.64 billion using a 
discount rate of 7 percent, and $25.80 billion using a discount rate of 
3 percent.
    The cumulative emissions reductions at TSL 5 are 111 Mt of 
CO<INF>2</INF>, 34.9 thousand tons of SO<INF>2</INF>, 203 thousand tons 
of NO<INF>X</INF>, 0.24 tons of Hg, 914 thousand tons of 
CH<INF>4</INF>, and 1.10 thousand tons of N<INF>2</INF>O. The estimated 
monetary value of the climate benefits from reduced GHG emissions 
(associated with the average SC-GHG at a 3-percent discount rate) at 
TSL 5 is $5.87 billion. The estimated monetary value of the health 
benefits from reduced SO<INF>2</INF> and NO<INF>X</INF> emissions at 
TSL 5 is $4.50 billion using a 7-percent discount rate and $11.50 
billion using a 3-percent discount rate.
    Using a 7-percent discount rate for consumer benefits and costs, 
health benefits from reduced SO<INF>2</INF> and NO<INF>X</INF> 
emissions, and the 3-percent discount rate case for climate benefits 
from reduced GHG emissions, the estimated total NPV at TSL 5 is $19.01 
billion. Using a 3-percent discount rate for all benefits and costs, 
the estimated total NPV at TSL 5 is $43.17 billion. The estimated total 
NPV is provided for additional information, however DOE primarily 
relies upon the NPV of consumer benefits when determining whether a 
standard level is economically justified.
    At TSL 5, for the largest product classes, which are 3, 5, 5A, and 
7, there is a life-cycle cost savings of $43.46, $45.47, $122.18, and 
$73.96 and a payback period of 5.3 years, 6.1 years, 6.0 years and 6.2 
years, respectively. For these product classes, the fraction of 
customers experiencing a net LCC cost is 34.2 percent, 39.4 percent, 
39.4 percent and 42.6 percent with increases in first cost of $52.69, 
$69.25, $161.65, and $121.58, respectively. Overall, 33 percent of 
refrigerators, refrigerator-freezers, and freezers consumers would 
experience a net cost and the average LCC savings are positive for all 
product classes.
    At TSL 5, an estimated 16 percent of all low-income households 
experience a net cost, including 11 percent of low-income households 
with a top-mount or single-door refrigerator-freezer (represented by PC 
3 and used by 72 percent of low-income households) and 32 percent of 
low-income households with a side-by-side refrigerator-freezer 
(represented by PC 7 and used by 19 percent of low-income households). 
More than half of low-income PC 7 consumers with a net cost experience 
a net cost of at least $40 and while low-income PC 7 consumers 
experience an average LCC savings of $132.77 at TSL 5, there are larger 
average LCC savings at TSL 4 ($161.87) and substantially fewer low-
income PC 7 consumers would experience a net cost (0.6 percent) at that 
TSL. Further, the incremental increase in purchase price at TSL 5 for 
PC 7 is $121.58, which may be difficult for low-income homeowners to 
afford.
    At TSL 5, the projected change in INPV ranges from a decrease of 
$1.07 billion to a decrease of $844.2 million, which corresponds to 
decreases of 21.7 percent and 17.2 percent, respectively. DOE estimates 
that industry must invest $1.40 billion to comply with standards set at 
TSL 5.
    DOE estimates that approximately 14 percent of refrigerator, 
refrigerator-freezer, and freezer annual shipments meet the TSL 5 
efficiencies. For standard-size refrigerator-freezers, which account 
for approximately 70 percent of total annual shipments, approximately 1 
percent of shipments meet the efficiencies required at TSL 5. Compared 
to max-tech, more manufacturers offer standard-size refrigerator-
freezer products that meet the required efficiencies, however, many 
manufacturers do not offer products that meet this level. Of the 22 
OEMs offering PC 3 products, three OEMs offer models that meet the 
efficiency level required. Of the 22 OEMs offering PC 5 products, 14 
OEMs offer models that meet the efficiency level required. Of the 11 
OEMs offering PC 7 products, only one OEM offers models that meet the 
efficiency level required.
    The manufacturers that do not currently offer models that meet TSL 
5 efficiencies would need to develop new product platforms. Updates 
could include incorporating variable defrost, BLDC evaporator fan 
motors, and high-efficiency VSCs. Additionally, some product classes 
could require the use of VIPs. DOE expects manufacturers would likely 
need to incorporate some VIPs into PC 5 and PC 7 designs, but not to 
the extent required at max-tech. However, DOE expects manufacturers 
would need to incorporate the max-tech design options for PC 5A, which 
includes the use of VIPs for roughly half the cabinet surface (side 
walls and doors) to meet TSL 5 efficiencies. As discussed in section 
IV.J.2.c of this document, the inclusion of VIPs in product design 
necessitates large investments in tooling and significant changes to 
production plants. Furthermore, given that only 1 percent of current 
standard-size refrigerator-freezer shipments meet TSL 5 efficiency 
levels, the manufacturers that are currently able to meet TSL 5 would 
need to scale up manufacturing capacity of compliant models. DOE 
anticipates conversion costs as high as $1.40 billion because the 
majority of product platforms in the industry would require redesign 
and investment.
    The Secretary concludes that at TSL 5 for refrigerators, 
refrigerator-freezers, and freezers, the benefits of energy savings, 
positive NPV of consumer benefits, emission reductions, and the 
estimated monetary value of the emissions reductions would be 
outweighed by the economic burden on consumers, particularly low-income 
consumers of side-by-side refrigerator-freezers, and the impacts on 
manufacturers, including the large potential reduction in INPV and the 
lack of manufacturers currently offering

[[Page 3105]]

standard-size refrigerator-freezer products meeting the efficiency 
levels required at this TSL. Specifically, only one OEM currently 
offers any PC 7 models that meet the TSL 5 efficiencies. At TSL 5, 32 
percent of low-income PC 7 consumers would experience a net cost and 
the incremental increase in purchase price of $121.58 may be difficult 
for low-income homeowners to afford. Consequently, the Secretary has 
concluded that TSL 5 is not economically justified.
    DOE then considered the Recommended TSL (i.e., TSL 4). For 
representative product classes other than PC 5A, PC 7, and PC 9, this 
TSL represents the same efficiency levels as TSL 5.\108\ Thus, the 
Recommended TSL represents similar design options as TSL 5, except for 
PC 5A, PC 7, and PC 9. For PC 7, DOE expects manufacturers would not 
require the use of VIPs to meet the required efficiency level. For PC 
5A, DOE expects manufacturers would require less VIP surface area to 
meet the required efficiency level. For PC 9, DOE expects manufacturers 
to implement variable speed compressor systems to meet required 
standards. DOE estimates that approximately 14 percent of annual 
shipments across all refrigerator, refrigerator-freezer, and freezer 
product classes currently meet the efficiencies required. For the 
Recommended TSL, DOE's analysis utilized the January 31, 2029 (or 
January 31, 2030, for some product classes) compliance dates specified 
in the Joint Agreement. The Recommended TSL would save an estimated 
5.61 quads of energy, an amount DOE considers significant. Under the 
Recommended TSL, the NPV of consumer benefit would be $9.04 billion 
using a discount rate of 7 percent, and $26.98 billion using a discount 
rate of 3 percent.
---------------------------------------------------------------------------

    \108\ For all TSLs except the Recommended TSL, the efficiency 
levels required for non-representative product classes are the same 
as the efficiency levels required for the associated directly 
analyzed product classes. However, as noted in section V.A of this 
document, the Recommended TSL from the Joint Agreement includes 
standard levels for some non-representative product classes that 
differ from their associated representative product class. Thus, in 
addition to the representative PC 5A, PC 7, and PC 9, the efficiency 
levels required for non-representative PC 9A-BI and PC 12 at the 
Recommended TSL also differ from the efficiency levels required at 
TSL 5.
---------------------------------------------------------------------------

    The cumulative emissions reductions at the Recommended TSL are 101 
Mt of CO<INF>2</INF>, 31.6 thousand tons of SO<INF>2</INF>, 186 
thousand tons of NO<INF>X</INF>, 0.22 tons of Hg, 846.5 thousand tons 
of CH<INF>4</INF>, and 0.99 thousand tons of N<INF>2</INF>O. The 
estimated monetary value of the climate benefits from reduced GHG 
emissions (associated with the average SC-GHG at a 3-percent discount 
rate) at the Recommended TSL is $5.02 billion. The estimated monetary 
value of the health benefits from reduced SO<INF>2</INF> and 
NO<INF>X</INF> emissions at the Recommended TSL is $3.45 billion using 
a 7-percent discount rate and $9.80 billion using a 3-percent discount 
rate.
    Using a 7-percent discount rate for consumer benefits and costs, 
health benefits from reduced SO<INF>2</INF> and NO<INF>X</INF> 
emissions, and the 3-percent discount rate case for climate benefits 
from reduced GHG emissions, the estimated total NPV at the Recommended 
TSL is $17.51 billion. Using a 3-percent discount rate for all benefits 
and costs, the estimated total NPV at the Recommended TSL is $41.80 
billion. The estimated total NPV is provided for additional 
information, however DOE primarily relies upon the NPV of consumer 
benefits when determining whether a standard level is economically 
justified.
    At the Recommended TSL, for the largest product classes, which are 
3, 5, 5A, and 7, there is a life-cycle cost savings of $50.91, $55.23, 
$133.27, and $142.56 and a payback period of 4.8 years, 5.6 years, 4.1 
years, and 1.6 years, respectively. For these product classes, the 
fraction of customers experiencing a net LCC cost is 28.3 percent, 33.6 
percent, 19.8 percent, and 0.5 percent with increases in first cost of 
$47.67, $62.72, $81.32, and $24.39, respectively. Overall, 24.4 percent 
of refrigerators, refrigerator-freezers, and freezers consumers would 
experience a net cost and the average LCC savings are positive for all 
product classes.
    At the Recommended TSL, 9 percent of low-income households with a 
top-mount or single-door refrigerator-freezer (represented by PC 3 and 
used by 72 percent of low-income households) and 0.6 percent of low-
income households with a side-by-side refrigerator-freezer (represented 
by PC 7 and used by 19 percent of low-income households) experience a 
net cost. Additionally, the incremental increase in purchase price is 
$24.39 for low-income PC 7 homeowners at the Recommended TSL, 
substantially lower than the incremental increase in purchase price of 
$121.58 at TSL 5.
    At the Recommended TSL, the projected change in INPV ranges from a 
decrease of $504.4 million to a decrease of $383.5 million, which 
correspond to decreases of 10.3 percent and 7.8 percent, respectively. 
DOE estimates that industry must invest $830.3 million comply with 
standards set at the Recommended TSL. DOE estimates that approximately 
14 percent of refrigerator, refrigerator-freezer, and freezer annual 
shipments meet the Recommended TSL efficiencies.
    Compared to TSL 5, more manufacturers offer standard-size 
refrigerator freezer products that meet the required efficiencies since 
PC 7 has a lower required efficiency level at the Recommended TSL. For 
PC 7, which accounts for 11 percent of shipments, three OEMs offer 
products that meet the efficiency level required. Furthermore, DOE does 
not expect manufacturers would need to incorporate VIPs into PC 7 
designs to meet the efficiencies required at the Recommended TSL. For 
PC 5 and PC 5A, DOE understands the two product classes often share the 
same production lines, with shared cabinet architecture and tooling. 
DOE expects manufacturers would likely need to incorporate some VIPs 
into PC 5A designs, but not to the extent required at TSL 5 and TSL 6. 
Thus, for the 10 OEMs that manufacture both PC 5 and PC 5A, DOE expects 
manufacturers could implement similar cabinet upgrades (i.e., partial 
VIP) for PC 5 and PC 5A designs to achieve the efficiencies required at 
this level.
    For all TSLs considered in this direct final rule--except for the 
Recommended TSL--DOE is bound by the 3-year lead time requirements in 
EPCA when determining compliance dates (i.e., compliance with amended 
standards required in 2027). For the Recommended TSL, DOE's analysis 
utilized the January 31, 2029 (or January 31, 2030, for some product 
classes) compliance dates specified in the Joint Agreement as they were 
an integral part of the multi-product joint recommendation. These 
compliance dates provide manufacturers the flexibility to spread 
capital requirements, engineering resources, and other conversion 
activities over a longer period of time depending on the individual 
needs of each manufacturer. Furthermore, these delayed compliance dates 
provide additional lead time and certainty for suppliers of components 
that improve efficiency. The Recommended TSL mitigates risks raised by 
AHAM and multiple manufacturers in response to the February 2023 NOPR 
regarding the ability for VSC and VIP component suppliers to increase 
supply of these key components in the 3-year lead time required by 
EPCA.
    After considering the analysis and weighing the benefits and 
burdens, the Secretary has concluded that a standard set at the 
Recommended TSL for refrigerators, refrigerator-freezers, and freezers 
is economically justified. At this TSL, the average LCC savings are 
positive for all product classes for

[[Page 3106]]

which an amended standard is considered. An estimated 24.4 percent of 
all refrigerator, refrigerator-freezer, and freezer consumers 
experience a net cost. An estimated 9 percent of low-income households 
with a top-mount or single-door refrigerator-freezer (represented by PC 
3 and used by 72 percent of low-income households) and 0.6 percent of 
low-income households with a side-by-side refrigerator-freezer 
(represented by PC 7 and used by 19 percent of low-income households), 
experience a net cost, which is a significantly lower percentage than 
under TSL 5. DOE notes that for low-income PC 7 consumers, as well as 
across all PC 7 consumers, the Recommended TSL represents the largest 
average LCC savings of any TSL. The FFC national energy savings are 
significant and the NPV of consumer benefits is positive at the 
Recommended TSL using both a 3-percent and 7-percent discount rate. 
Notably, the benefits to consumers vastly outweigh the cost to 
manufacturers. At the Recommended TSL, the NPV of consumer benefits, 
even measured at the more conservative discount rate of 7 percent is 
over 17 times higher than the maximum estimated manufacturers' loss in 
INPV. The standard levels at the Recommended TSL are economically 
justified even without weighing the estimated monetary value of 
emissions reductions. When those emissions reductions are included--
representing $5.02 billion in climate benefits (associated with the 
average SC-GHG at a 3-percent discount rate), and $9.80 billion (using 
a 3-percent discount rate) or $3.45 billion (using a 7-percent discount 
rate) in health benefits--the rationale becomes stronger still.
    As stated, DOE conducts the walk-down analysis to determine the TSL 
that represents the maximum improvement in energy efficiency that is 
technologically feasible and economically justified as required under 
EPCA. DOE notes 72 percent of low-income households have a top-mount 
refrigerator-freezer (represented by PC 3) and that an estimated 9 
percent of low-income PC 3 households experience a net cost at the 
Recommended TSL, whereas an estimated 6 percent of low-income 
households with a top-mount refrigerator-freezer experience a net cost 
at TSL 3. However, the average LCC savings for low-income PC 3 
consumers are $22.05 higher at the Recommended TSL than at TSL 3. 
Further, compared to TSL 3, it is estimated that the Recommended TSL 
would result in additional FFC national energy savings of 0.9 quads. 
These additional savings and benefits at the Recommended TSL are 
significant. DOE considers the impacts to be, as a whole, economically 
justified at the Recommended TSL.
    Although DOE considered amended standard levels for refrigerators, 
refrigerator-freezers, and freezers by grouping the efficiency levels 
for each product class into TSLs, DOE evaluates all analyzed efficiency 
levels in its analysis. In general, the standard level represents the 
maximum energy savings that does not result in a large percentage of 
consumers experiencing a net LCC cost. For example, for PC 5, more than 
half of consumers experience a net cost at EL 3. In the case of PC 7, 
for which DOE found that a relatively higher percentage of low-income 
consumers may experience net costs at higher efficiency levels, at the 
standard level chosen, 0.6 percent of low-income households with side-
by-side refrigerator-freezers will experience a potential burden. The 
ELs at the standard level result in positive LCC savings for all 
product classes, significantly reduce the number of consumers 
experiencing a net cost, and reduce the decrease in INPV and conversion 
costs to the point where DOE has concluded they are economically 
justified, as discussed for the Recommended TSL in the preceding 
paragraphs.
    Therefore, based on the previous considerations, DOE adopts the 
energy conservation standards for refrigerators, refrigerator-freezers, 
and freezers at the Recommended TSL.
    While DOE considered each potential TSL under the criteria laid out 
in 42 U.S.C. 6295(o) as discussed above, DOE notes that the Recommended 
TSL for refrigerators, refrigerator-freezers, and freezers adopted in 
this direct final rule is part of a multi-product Joint Agreement 
covering six rulemakings (refrigerators, refrigerator-freezers, and 
freezers; miscellaneous refrigeration products; conventional cooking 
products; residential clothes washers; consumer clothes dryers; and 
dishwashers). The signatories indicate that the Joint Agreement for the 
six rulemakings should be considered as a joint statement of 
recommended standards, to be adopted in its entirety. As discussed in 
section V.B.2.e of this document, many refrigerator, refrigerator-
freezer, and freezer OEMs also manufacture miscellaneous refrigeration 
products, conventional cooking products, residential clothes washers, 
consumer clothes dryers, and dishwashers. Rather than requiring 
compliance with five amended standards in a single year (2027),\109\ 
the negotiated multi-product Joint Agreement staggers the compliance 
dates for the five amended standards over a 4-year period (2027-2030). 
In response to the February 2023 NOPR, AHAM and individual 
manufacturers expressed concerns about the timing of ongoing home 
appliance rulemakings. Specifically, AHAM commented that the 
combination of the stringency of DOE's proposals, the short lead-in 
time required under EPCA to comply with standards, and the overlapping 
timeframe of multiple standards affecting the same manufacturers 
represents significant cumulative regulatory burden for the home 
appliance industry. (AHAM, No. 69 at pp. 20-21) AHAM has submitted 
similar comments to other ongoing consumer product rulemakings.\110\ As 
AHAM is a key signatory of the Joint Agreement, DOE understands that 
the compliance dates recommended in the Joint Agreement would help 
reduce cumulative regulatory burden. These compliance dates help 
relieve concern on the part of some manufacturers about their ability 
to allocate sufficient resources to comply with multiple concurrent 
amended standards, about the need to align compliance dates for 
products that are typically designed or sold as matched pairs, and 
about the ability of their suppliers to ramp up production of key 
components. The Joint Agreement also provides additional years of 
regulatory certainty for manufacturers and their suppliers while still 
achieving the maximum improvement in energy efficiency that is 
technologically feasible and economically justified.

    \109\ The refrigerators, refrigerator-freezers, and freezers (88 
FR 12452); consumer conventional cooking products (88 FR 6818); 
residential clothes washers (88 FR 13520); consumer clothes dryers 
(87 FR 51734); and dishwashers (88 FR 32514) utilized a 2027 
compliance year for analysis at the proposed rule stage. 
Miscellaneous refrigeration products (88 FR 12452) utilized a 2029 
compliance year for the NOPR analysis.
    \110\ AHAM has submitted written comments regarding cumulative 
regulatory burden for the other five rulemakings included in the 
multi-product Joint Agreement. AHAM's written comments on cumulative 
regulatory burden are available at: www.regulations.gov/comment/EERE-2020-BT-STD-0039-0031 (pp. 12-15) for miscellaneous

2. Annualized Benefits and Costs of the Adopted Standards
    The benefits and costs of the adopted standards can also be 
expressed in terms of annualized values. The annualized net benefit is 
(1) the annualized national economic value (expressed in 2022$) of the 
benefits from operating products that meet the adopted standards 
(consisting primarily of operating cost savings from using less 
energy), minus increases in product purchase costs, and (2) the 
annualized monetary value of the climate and health benefits.
    Table V.49 shows the annualized values for consumer refrigerator, 
refrigerator-freezers, and freezers under the Recommended TSL expressed 
in 2022$. The results under the primary estimate are as follows.
    Using a 7-percent discount rate for consumer benefits and costs and 
health benefits from reduced NO<INF>X</INF> and SO<INF>2</INF> 
emissions, and the 3-percent discount rate case for climate benefits 
from reduced GHG emissions, the estimated cost of the standards adopted 
in this rule is $590.5 million per year in increased equipment costs, 
while the estimated annual monetized benefits are $1.7 billion in 
reduced equipment operating costs, $303.8 million in climate benefits, 
and $410.6 million in health benefits. In this case, the net benefit 
would amount to $1.8 billion per year.
    Using a 3-percent discount rate for all benefits and costs, the 
estimated cost of the standards is $567.5 million per year in increased 
equipment costs, while the estimated annual monetized benefits are $2.2 
billion in reduced operating costs, $303.8 million in climate benefits, 
and $592.9 million in health benefits. In this case, the net benefit 
would amount to $2.5 billion per year.

Note: This table presents present value (in 2022$) of the costs and benefits associated with refrigerators,
  refrigerator-freezers, and freezers shipped in 2029-2058 for the product classes listed in Table I.1 and
  shipped in 2030-2059 for the product classes listed in Table I.2. These results include benefits which accrue
  after 2056 from the products shipped in 2029-2058 for the product classes listed in Table I.1 and shipped in
  2030-2059 for the product classes listed in Table I.2. The Primary, Low Net Benefits, and High Net Benefits
  Estimates utilize projections of energy prices from the AEO2023 Reference case, Low Economic Growth case, and
  High Economic Growth case, respectively. In addition, incremental equipment costs reflect a medium decline
  rate in the Primary Estimate, a low decline rate in the Low Net Benefits Estimate, and a high decline rate in
  the High Net Benefits Estimate. The methods used to derive projected price trends are explained in section
  IV.H.3 of this document. Note that the Benefits and Costs may not sum to the Net Benefits due to rounding.
* Climate benefits are calculated using four different estimates of the global SC-GHG (see section IV.L of this
  document). For presentational purposes of this table, the climate benefits associated with the average SC-GHG
  at a 3-percent discount rate are shown; however, DOE emphasizes the importance and value of considering the
  benefits calculated using all four sets of SC-GHG estimates. To monetize the benefits of reducing GHG
  emissions, this analysis uses the interim estimates presented in the Technical Support Document: Social Cost
  of Carbon, Methane.
** Health benefits are calculated using benefit-per-ton values for NOX and SO2. DOE is currently only monetizing
  (for SO2 and NOX) PM2.5 precursor health benefits and (for NOX) ozone precursor health benefits, but will
  continue to assess the ability to monetize other effects such as health benefits from reductions in direct
  PM2.5 emissions. See section IV.L of this document for more details.

[[Page 3109]]

 
[dagger] Total benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with 3-
  percent discount rate, but DOE does not have a single central SC-GHG point estimate.
[Dagger][Dagger] Operating Cost Savings are calculated based on the life-cycle costs analysis and national
  impact analysis as discussed in detail below. See sections IV.F and IV.H of this document. DOE's NIA includes
  all impacts (both costs and benefits) along the distribution chain beginning with the increased costs to the
  manufacturer to manufacture the product and ending with the increase in price experienced by the consumer. DOE
  also separately conducts a detailed analysis on the impacts on manufacturers (the MIA). See section IV.J of
  this document. In the detailed MIA, DOE models manufacturers' pricing decisions based on assumptions regarding
  investments, conversion costs, cashflow, and margins. The MIA produces a range of impacts, which is the rule's
  expected impact on the INPV. The change in INPV is the present value of all changes in industry cash flow,
  including changes in production costs, capital expenditures, and manufacturer profit margins. The annualized
  change in INPV is calculated using the industry weighted average cost of capital value of 9.1 percent that is
  estimated in the manufacturer impact analysis (see chapter 12 of the direct final rule TSD for a complete
  description of the industry weighted average cost of capital). For refrigerators, refrigerator-freezers, and
  freezers, those values are -$48.7 million to -$37.0 million. DOE accounts for that range of likely impacts in
  analyzing whether a TSL is economically justified. See section V.C of this document. DOE is presenting the
  range of impacts to the INPV under two manufacturer markup scenarios: the Preservation of Gross Margin
  scenario, which is the manufacturer markup scenario used in the calculation of Consumer Operating Cost Savings
  in this table, and the Preservation of Operating Profit Markup scenario, where DOE assumed manufacturers would
  not be able to increase per-unit operating profit in proportion to increases in manufacturer production costs.
  DOE includes the range of estimated annualized change in INPV in the above table, drawing on the MIA explained
  further in section IV.J of this document, to provide additional context for assessing the estimated impacts of
  this direct final rule to society, including potential changes in production and consumption, which is
  consistent with OMB's Circular A-4 and E.O. 12866. If DOE were to include the INPV into the annualized net
  benefit calculation for this direct final rule, the annualized net benefits would range from $2,480.9 million
  to $2,492.6 million at 3-percent discount rate and would range from $1,742.2 million to $1,753.9 million at 7-
  percent discount rate. Parentheses ( ) indicate negative values.

VI. Procedural Issues and Regulatory Review

A. Review Under Executive Orders 12866, 13563, and 14094

    Executive Order (``E.O.'') 12866, ``Regulatory Planning and 
Review,'' as supplemented and reaffirmed by E.O. 13563, ``Improving 
Regulation and Regulatory Review,'' 76 FR 3821 (Jan. 21, 2011), and 
amended by E.O. 14094, ``Modernizing Regulatory Review,'' 88 FR 21879 
(April 11, 2023), requires agencies, to the extent permitted by law, to 
(1) propose or adopt a regulation only upon a reasoned determination 
that its benefits justify its costs (recognizing that some benefits and 
costs are difficult to quantify); (2) tailor regulations to impose the 
least burden on society, consistent with obtaining regulatory 
objectives, taking into account, among other things, and to the extent 
practicable, the costs of cumulative regulations; (3) select, in 
choosing among alternative regulatory approaches, those approaches that 
maximize net benefits (including potential economic, environmental, 
public health and safety, and other advantages; distributive impacts; 
and equity); (4) to the extent feasible, specify performance 
objectives, rather than specifying the behavior or manner of compliance 
that regulated entities must adopt; and (5) identify and assess 
available alternatives to direct regulation, including providing 
economic incentives to encourage the desired behavior, such as user 
fees or marketable permits, or providing information upon which choices 
can be made by the public. DOE emphasizes as well that E.O. 13563 
requires agencies to use the best available techniques to quantify 
anticipated present and future benefits and costs as accurately as 
possible. In its guidance, the Office of Information and Regulatory 
Affairs (``OIRA'') in the Office of Management and Budget (``OMB'') has 
emphasized that such techniques may include identifying changing future 
compliance costs that might result from technological innovation or 
anticipated behavioral changes. For the reasons stated in the preamble, 
this final regulatory action is consistent with these principles.
    Section 6(a) of E.O. 12866 also requires agencies to submit 
``significant regulatory actions'' to OIRA for review. OIRA has 
determined that this final regulatory action constitutes a 
``significant regulatory action'' within the scope of section 3(f)(1) 
of E.O. 12866. Accordingly, pursuant to section 6(a)(3)(C) of E.O. 
12866, DOE has provided to OIRA an assessment, including the underlying 
analysis, of benefits and costs anticipated from the final regulatory 
action, together with, to the extent feasible, a quantification of 
those costs; and an assessment, including the underlying analysis, of 
costs and benefits of potentially effective and reasonably feasible 
alternatives to the planned regulation, and an explanation why the 
planned regulatory action is preferable to the identified potential 
alternatives. These assessments are summarized in this preamble and 
further detail can be found in the technical support document for this 
rulemaking.

B. Review Under the Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of an initial regulatory flexibility analysis (``IRFA'') 
and a final regulatory flexibility analysis (``FRFA'') for any rule 
that by law must be proposed for public comment, unless the agency 
certifies that the rule, if promulgated, will not have a significant 
economic impact on a substantial number of small entities. As required 
by E.O. 13272, ``Proper Consideration of Small Entities in Agency 
Rulemaking,'' 67 FR 53461 (Aug. 16, 2002), DOE published procedures and 
policies on February 19, 2003, to ensure that the potential impacts of 
its rules on small entities are properly considered during the 
rulemaking process. 68 FR 7990. DOE has made its procedures and 
policies available on the Office of the General Counsel's website 
(www.energy.gov/gc/office-general-counsel).
    DOE is not obligated to prepare a regulatory flexibility analysis 
for this rulemaking because there is not a requirement to publish a 
general notice of proposed rulemaking under the Administrative 
Procedure Act. See 5 U.S.C. 601(2), 603(a). As discussed previously, 
DOE has determined that the Joint Agreement meets the necessary 
requirements under EPCA to issue this direct final rule for energy 
conservation standards for refrigerators, refrigerator-freezers, and 
freezers under the procedures in 42 U.S.C. 6295(p)(4). DOE notes that 
the NOPR for energy conservation standards for refrigerators, 
refrigerator-freezers, and freezers published elsewhere in the Federal 
Register contains an IRFA.

C. Review Under the Paperwork Reduction Act

    Manufacturers of consumer refrigerators, refrigerator-freezers, and 
freezers must certify to DOE that their products comply with any 
applicable energy conservation standards. In certifying compliance, 
manufacturers must test their products according to the DOE test 
procedures for consumer refrigerators, refrigerator-freezers, and 
freezers, including any amendments adopted for those test procedures. 
DOE has established regulations for the certification and recordkeeping 
requirements for all covered consumer products and commercial 
equipment, including consumer refrigerators, refrigerator-freezers, and 
freezers. (See

[[Page 3110]]

generally 10 CFR part 429) The collection-of-information requirement 
for the certification and recordkeeping is subject to review and 
approval by OMB under the Paperwork Reduction Act (``PRA''). This 
requirement has been approved by OMB under OMB control number 1910-
1400. Public reporting burden for the certification is estimated to 
average 35 hours per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information.
    Notwithstanding any other provision of the law, no person is 
required to respond to, nor shall any person be subject to a penalty 
for failure to comply with, a collection of information subject to the 
requirements of the PRA, unless that collection of information displays 
a currently valid OMB Control Number.

D. Review Under the National Environmental Policy Act of 1969

    Pursuant to the National Environmental Policy Act of 1969 
(``NEPA''), DOE has analyzed this rule in accordance with NEPA and 
DOE's NEPA implementing regulations (10 CFR part 1021). DOE has 
determined that this rule qualifies for categorical exclusion under 10 
CFR part 1021, subpart D, appendix B, B5.1, because it is a rulemaking 
that establishes energy conservation standards for consumer products or 
industrial equipment, none of the exceptions identified in B5.1(b) 
apply, no extraordinary circumstances exist that require further 
environmental analysis, and it meets the requirements for application 
of a categorical exclusion. See 10 CFR 1021.410. Therefore, DOE has 
determined that promulgation of this rule is not a major Federal action 
significantly affecting the quality of the human environment within the 
meaning of NEPA, and does not require an environmental assessment or an 
environmental impact statement.

E. Review Under Executive Order 13132

    E.O. 13132, ``Federalism,'' 64 FR 43255 (Aug. 10, 1999), imposes 
certain requirements on Federal agencies formulating and implementing 
policies or regulations that preempt State law or that have federalism 
implications. The Executive order requires agencies to examine the 
constitutional and statutory authority supporting any action that would 
limit the policymaking discretion of the States and to carefully assess 
the necessity for such actions. The Executive order also requires 
agencies to have an accountable process to ensure meaningful and timely 
input by State and local officials in the development of regulatory 
policies that have federalism implications. On March 14, 2000, DOE 
published a statement of policy describing the intergovernmental 
consultation process it will follow in the development of such 
regulations. 65 FR 13735.
    In the February 2023 NOPR, DOE tentatively determined that the 
proposed rule would not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government. 88 FR 13616. Furthermore, DOE stated that EPCA 
governs and prescribes Federal preemption of State regulations as to 
energy conservation for the products that are the subject of this 
proposed rule and that States can petition DOE for exemption from such 
preemption to the extent, and based on criteria, set forth in EPCA. Id. 
(citing 42 U.S.C. 6297). Accordingly, DOE concluded that no further 
action was required by E.O. 13132.
    The AGs of TN, AL, et al. submitted a joint comment that DOE's 
analysis is woefully deficient. The AGs of TN, AL, et al. commented 
that this determination is incorrect because, in their view, the 
Proposed Standards have significant federalism implications within the 
meaning of Executive Order 13132. The AGs of TN, AL, et al. go on to 
state that if the Proposed Standards are promulgated, ``[a]ny State 
regulation which sets forth procurement standards'' relating to 
refrigerators, refrigerator-freezers, or freezers, is ``superseded'' 
unless those ``standards are more stringent than the corresponding 
Federal energy conservation standards. The AGs of TN, AL, et al. argue 
that preempting--even in part--State procurement rules is plainly a 
direct effect on the States and alters the federal-state relationship 
by directly regulating the States. See Exec. Order No. 13132 Sec.  
6(c).'' (The AGs of TN, AL, et al., No. 68 at p. 3) Further, the AGs of 
TN, et al., argue that section 6(b) of E.O. 13132 applies because 
states are purchasers of refrigerators, refrigerator-freezers, and 
freezers; therefore, reliance interests are implicated and subject the 
states to substantial direct compliance costs. (Id. at 2-3)
    DOE reiterates that this direct final rule does not have 
significant federalism implications. DOE has examined this rule and has 
determined that it would not have a substantial direct effect on the 
States, on the relationship between the National Government and the 
States, or on the distribution of power and responsibilities among the 
various levels of government. EPCA governs and expressly prescribes 
Federal preemption of State regulations as to energy conservation for 
the products that are the subject of this direct final rule. States can 
petition DOE for exemption from such preemption to the extent, and 
based on criteria, set forth in EPCA. (42 U.S.C. 6297) Therefore, no 
further action is required by Executive Order 13132.
    Even if DOE were to find otherwise, with regards to the AGs of TN, 
AL et al.'s arguments regarding section 6(c) of E.O. 13132, DOE notes 
that the AGs of TN, AL et al. do not provide any examples of a state 
procurement rule that conflicts with the standards adopted in this 
rulemaking and DOE is not aware of any such conflicts. While it is 
possible that a State may have to revise its procurement standards to 
reflect the new standards, States can petition DOE for exemption from 
such preemption to the extent, and based on criteria, set forth in 
EPCA. Absent such information, DOE concludes that no further action 
would be required by E.O. 13132 even if the Executive order were 
applicable here. Moreover, assuming the hypothetical preemption alleged 
by the AGs of TN, AL et al. were to present itself, DOE notes that, 
like all interested parties, states were presented with an opportunity 
to engage in the rulemaking process early in the development of the 
proposed rule. Prior to publishing the proposed rulemaking, on November 
15, 2019, DOE published and sought public comment on a request for 
information (``RFI'') to collect data and information to help DOE 
determine whether any new or amended standards for consumer 
refrigerators, refrigerator-freezers, and freezers would result in a 
significant amount of additional energy savings and whether those 
standards would be technologically feasible and economically justified. 
84 FR 62470 (``November 2019 RFI''). DOE then published a notice of 
public meeting and availability of the preliminary TSD on October 15, 
2021, and sought public comment again. (``October 2021 Preliminary 
Analysis''). 86 FR 57378. DOE then held a public meeting on December 1, 
2021, to discuss and receive comments on the preliminary TSD, which was 
open to the public, including state agencies. As such, states were 
provided the opportunity for meaningful and substantial input as 
envisioned by the Executive order.
    With regards to the AGs of TN, AL et al.'s arguments regarding 
section 6(b) of E.O. 13132, the potential effect alleged by the AGs of 
TN, AL, et al. is the same

[[Page 3111]]

effect experienced by all refrigerator consumers--models manufactured 
after a specific date must meet revised efficiency standards. This 
impact does not constitute a ``substantial'' impact as required by the 
Executive order. Further, contrary to the assertions of the AGs of TN 
et al., the direct final rule is required by law. As noted previously, 
where DOE determines that a proposed amended standard is designed to 
achieve the maximum improvement in energy efficiency and is both 
technologically feasible and economically justified, it must adopt it. 
Therefore, section 6(b) is inapplicable. E.O. 13132, section6(b) 
(applicable to regulation ``that is not required by statute'').

F. Review Under Executive Order 12988

    With respect to the review of existing regulations and the 
promulgation of new regulations, section 3(a) of E.O. 12988, ``Civil 
Justice Reform,'' imposes on Federal agencies the general duty to 
adhere to the following requirements: (1) eliminate drafting errors and 
ambiguity, (2) write regulations to minimize litigation, (3) provide a 
clear legal standard for affected conduct rather than a general 
standard, and (4) promote simplification and burden reduction. 61 FR 
4729 (Feb. 7, 1996). Regarding the review required by section 3(a), 
section 3(b) of E.O. 12988 specifically requires that Executive 
agencies make every reasonable effort to ensure that the regulation (1) 
clearly specifies the preemptive effect, if any, (2) clearly specifies 
any effect on existing Federal law or regulation, (3) provides a clear 
legal standard for affected conduct while promoting simplification and 
burden reduction, (4) specifies the retroactive effect, if any, (5) 
adequately defines key terms, and (6) addresses other important issues 
affecting clarity and general draftsmanship under any guidelines issued 
by the Attorney General. Section 3(c) of E.O. 12988 requires Executive 
agencies to review regulations in light of applicable standards in 
section 3(a) and section 3(b) to determine whether they are met or it 
is unreasonable to meet one or more of them. DOE has completed the 
required review and determined that, to the extent permitted by law, 
this direct final rule meets the relevant standards of E.O. 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (``UMRA'') 
requires each Federal agency to assess the effects of Federal 
regulatory actions on State, local, and Tribal governments and the 
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). 
For a regulatory action likely to result in a rule that may cause the 
expenditure by State, local, and Tribal governments, in the aggregate, 
or by the private sector of $100 million or more in any one year 
(adjusted annually for inflation), section 202 of UMRA requires a 
Federal agency to publish a written statement that estimates the 
resulting costs, benefits, and other effects on the national economy. 
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to 
develop an effective process to permit timely input by elected officers 
of State, local, and Tribal governments on a ``significant 
intergovernmental mandate,'' and requires an agency plan for giving 
notice and opportunity for timely input to potentially affected small 
governments before establishing any requirements that might 
significantly or uniquely affect them. On March 18, 1997, DOE published 
a statement of policy on its process for intergovernmental consultation 
under UMRA. 62 FR 12820. DOE's policy statement is also available at 
www.energy.gov/sites/prod/files/gcprod/documents/umra_97.pdf.
    DOE has concluded that this direct final rule may require 
expenditures of $100 million or more in any one year by the private 
sector. Such expenditures may include (1) investment in research and 
development and in capital expenditures by consumer refrigerators, 
refrigerator-freezers, and freezers manufacturers in the years between 
the direct final rule and the compliance date for the new standards and 
(2) incremental additional expenditures by consumers to purchase 
higher-efficiency consumer refrigerators, refrigerator-freezers, and 
freezers, starting at the compliance date for the applicable standard.
    Section 202 of UMRA authorizes a Federal agency to respond to the 
content requirements of UMRA in any other statement or analysis that 
accompanies the direct final rule. (2 U.S.C. 1532(c)) The content 
requirements of section 202(b) of UMRA relevant to a private sector 
mandate substantially overlap the economic analysis requirements that 
apply under section 325(o) of EPCA and Executive Order 12866. The 
SUPPLEMENTARY INFORMATION section of this document and the TSD for this 
direct final rule respond to those requirements.
    Under section 205 of UMRA, DOE is obligated to identify and 
consider a reasonable number of regulatory alternatives before 
promulgating a rule for which a written statement under section 202 is 
required. (2 U.S.C. 1535(a)) DOE is required to select from those 
alternatives the most cost-effective and least burdensome alternative 
that achieves the objectives of the rule unless DOE publishes an 
explanation for doing otherwise, or the selection of such an 
alternative is inconsistent with law. As required by 42 U.S.C. 6295(m), 
this direct final rule establishes amended energy conservation 
standards for consumer refrigerators, refrigerator-freezers, and 
freezers that are designed to achieve the maximum improvement in energy 
efficiency that DOE has determined to be both technologically feasible 
and economically justified, as required by sections 6295(o)(2)(A) and 
6295(o)(3)(B). A full discussion of the alternatives considered by DOE 
is presented in chapter 17 of the TSD for this direct final rule.

H. Review Under Executive Order 12630

    Pursuant to E.O. 12630, ``Governmental Actions and Interference 
with Constitutionally Protected Property Rights,'' 53 FR 8859 (March 
18, 1988), DOE has determined that this rule would not result in any 
takings that might require compensation under the Fifth Amendment to 
the U.S. Constitution.

I. Review Under the Treasury and General Government Appropriations Act, 
2001

    Section 515 of the Treasury and General Government Appropriations 
Act, 2001 (44 U.S.C. 3516, note) provides for Federal agencies to 
review most disseminations of information to the public under 
information quality guidelines established by each agency pursuant to 
general guidelines issued by OMB. OMB's guidelines were published at 67 
FR 8452 (Feb. 22, 2002), and DOE's guidelines were published at 67 FR 
62446 (Oct. 7, 2002). Pursuant to OMB Memorandum M-19-15, Improving 
Implementation of the Information Quality Act (April 24, 2019), DOE 
published updated guidelines which are available at www.energy.gov/sites/prod/files/2019/12/f70/DOE%20Final%20Updated%20IQA%20Guidelines%20Dec%202019.pdf. DOE has 
reviewed this direct final rule under the OMB and DOE guidelines and 
has concluded that it is consistent with applicable policies in those 
guidelines.

J. Review Under Executive Order 13211

    E.O. 13211, ``Actions Concerning Regulations That Significantly 
Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 (May 22, 
2001), requires Federal agencies to prepare and submit to OIRA at OMB, 
a Statement of Energy

[[Page 3112]]

Effects for any significant energy action. A ``significant energy 
action'' is defined as any action by an agency that promulgates or is 
expected to lead to promulgation of a final rule, and that (1) is a 
significant regulatory action under Executive Order 12866, or any 
successor order; and (2) is likely to have a significant adverse effect 
on the supply, distribution, or use of energy, or (3) is designated by 
the Administrator of OIRA as a significant energy action. For any 
significant energy action, the agency must give a detailed statement of 
any adverse effects on energy supply, distribution, or use should the 
proposal be implemented, and of reasonable alternatives to the action 
and their expected benefits on energy supply, distribution, and use.
    DOE has concluded that this regulatory action, which sets forth 
amended energy conservation standards for consumer refrigerators, 
refrigerator-freezers, and freezers, is not a significant energy action 
because the standards are not likely to have a significant adverse 
effect on the supply, distribution, or use of energy, nor has it been 
designated as such by the Administrator at OIRA. Accordingly, DOE has 
not prepared a Statement of Energy Effects on this direct final rule.

K. Information Quality

    On December 16, 2004, OMB, in consultation with the Office of 
Science and Technology Policy (``OSTP''), issued its Final Information 
Quality Bulletin for Peer Review (``the Bulletin''). 70 FR 2664 (Jan. 
14, 2005). The Bulletin establishes that certain scientific information 
shall be peer-reviewed by qualified specialists before it is 
disseminated by the Federal Government, including influential 
scientific information related to agency regulatory actions. The 
purpose of the Bulletin is to enhance the quality and credibility of 
the Government's scientific information. Under the Bulletin, the energy 
conservation standards rulemaking analyses are ``influential scientific 
information,'' which the Bulletin defines as ``scientific information 
the agency reasonably can determine will have, or does have, a clear 
and substantial impact on important public policies or private sector 
decisions.'' 70 FR 2664, 2667.
    In response to OMB's Bulletin, DOE conducted formal peer reviews of 
the energy conservation standards development process and the analyses 
that are typically used and prepared a report describing that peer 
review.\111\ Generation of this report involved a rigorous, formal, and 
documented evaluation using objective criteria and qualified and 
independent reviewers to make a judgment as to the technical/
scientific/business merit, the actual or anticipated results, and the 
productivity and management effectiveness of programs and/or projects. 
Because available data, models, and technological understanding have 
changed since 2007, DOE has engaged with the National Academy of 
Sciences to review DOE's analytical methodologies to ascertain whether 
modifications are needed to improve DOE's analyses. DOE is in the 
process of evaluating the resulting report.\112\
