I. Authority and Background 
UPSs are a class of battery chargers 
and fall among the consumer products 
for which DOE is authorized to establish and amend energy conservation standards and test procedures. (42 U.S.C. 6295(u)) DOE’s energy conservation standards and test procedure for UPSs are currently prescribed at title 10 of the Code of Federal Regulations (‘‘CFR’’), part 430 section 32(z)(3); and 10 CFR part 430, subpart B, appendix Y (‘‘appendix Y’’) and appendix Y1 (‘‘appendix Y1’’). The following sections discuss DOE’s authority to establish a test procedure for UPSs and relevant background information regarding DOE’s consideration of the test procedure for this product. 
A. Authority 
The Energy Policy and Conservation 
Act, Public Law 94–163, as amended 
(‘‘EPCA’’),
1authorizes 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, which sets forth a variety of provisions designed to improve energy efficiency. These products include UPSs, the subject of this document. (42 U.S.C. 6295(u)) 
The energy conservation program 
under EPCA consists essentially of four parts: (1) testing, (2) labeling, (3) 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). 
The Federal testing requirements 
consist of test procedures that manufacturers of covered products must 
use as the basis for: (1) certifying to DOE that their products comply with the applicable energy conservation standards adopted pursuant to EPCA (42 U.S.C. 6295(s)), and (2) making other representations about the efficiency of those consumer products (42 U.S.C. 6293(c)). Similarly, DOE must use these test procedures to determine whether the products comply with relevant standards promulgated under EPCA. (42 U.S.C. 6295(s)) 
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) DOE may, however, grant waivers of Federal preemption for particular State laws or regulations, in accordance with the procedures and other provisions of EPCA. (42 U.S.C. 6297(d)) 
Under 42 U.S.C. 6293, EPCA sets forth 
the criteria and procedures DOE must follow when prescribing or amending test procedures for covered products. EPCA requires that any test procedures prescribed or amended under this section be reasonably designed to produce test results which measure energy efficiency, energy use or estimated annual operating cost of a covered product during a representative average use cycle or period of use, and not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3)) 
EPCA also requires that, at least once 
every seven years, DOE evaluate test procedures for each type of covered product, including UPSs, to determine whether amended test procedures would more accurately or fully comply with the requirements for the test procedures to not be unduly burdensome to conduct and be reasonably designed to produce test results that reflect energy efficiency, energy use, and estimated operating costs during a representative average use cycle or period of use. (42 U.S.C. 
6293(b)(1)(A)) 
If the Secretary determines, on her 
own behalf or in response to a petition by any interested person, that a test procedure should be prescribed or amended, the Secretary shall promptly publish in the Federal Register the proposed test procedure and afford interested persons an opportunity to present oral and written data, views, and arguments with respect to such procedure. The comment period on a proposed rule to amend a test procedure shall be at least 60 days and may not exceed 270 days. In prescribing or amending a test procedure, the Secretary shall take into account such information as the Secretary determines 
relevant to such procedure, including technological developments relating to energy use or energy efficiency of the type (or class) of covered products involved. (42 U.S.C. 6293(b)(2)). If DOE determines that test procedure revisions are not appropriate, DOE must publish its determination not to amend the test procedure. (42 U.S.C. 6293(b)(1)(A)(ii)) 
In addition, EPCA requires that DOE 
amend its test procedures for all covered products to integrate measures of standby mode and off mode energy consumption. (42 U.S.C. 6295(gg)(2)(A)). Standby mode and off mode energy consumption must be incorporated into the overall energy efficiency, energy consumption, or other energy descriptor for each covered product unless the current test procedures already account for and incorporate standby and off mode energy consumption or such 
integration is technically infeasible. If an integrated test procedure is technically infeasible, DOE must prescribe a separate standby mode and off mode energy use test procedure for the covered product, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)(ii)). Any such amendment must consider the most current versions of the International Electrotechnical Commission (IEC) Standard 62301
3and 
IEC Standard 620874as applicable. (42 
U.S.C. 6295(gg)(2)(A)) 
DOE is publishing this notice of 
proposed rulemaking (‘‘NOPR’’) in satisfaction of the 7-year review requirement specified in EPCA. (42 U.S.C. 6293(b)(1)(A)) 
B. Background 
On December 12, 2016, DOE amended 
its battery charger test procedure by 
publishing a final rule in the Federal Register that added a discrete test 
procedure for UPSs. 81 FR 89806 (‘‘December 2016 Final Rule’’). The December 2016 Final Rule incorporated by reference specific sections of the relevant industry standard for UPSs, with additional instructions, into the current battery charger test procedure published at appendix Y. 81 FR 89806, 89810. 
On September 8, 2022, DOE 
published a final rule in the Federal Register amending the existing test 
procedure at appendix Y for battery chargers and creating a new test procedure at appendix Y1 that

5The parenthetical reference provides a reference 
for information located in the docket of DOE’s 
rulemaking to develop a test procedure for UPSs. (Docket NO. EERE–2022–BT–TP–0005, which is maintained at www.regulations.gov). The references are arranged as follows: (commenter name, comment docket ID number, page of that document). 6As discussed further in section III.B of this 
document, DOE defines a UPS as a battery charger 
consisting of a combination of convertors, switches, and energy storage devices (such as batteries), constituting a power system for maintaining continuity of load power in case of input power failure. Appendices Y and Y1, section 2.27. expanded the scope of the battery 
charger test method to include open placement and fixed-position wireless battery chargers and established separate metrics for active mode, standby mode, and off mode for all battery chargers other than UPSs. 87 FR 55090 (‘‘September 2022 Final Rule’’). Manufacturers will be required to continue to use the amended test procedure in appendix Y until the compliance date of any new final rule establishing amended energy conservation standards based on the newly established test procedure in 
appendix Y1. 87 FR 55090, 55122. At such time that DOE establishes new 
standards for battery chargers other than UPSs using these new metrics, manufacturers would no longer use appendix Y and instead would be required to determine compliance using the updated test procedure at Y1. Id. at 
87 FR 55125. That final rule also 
replicated all aspects of testing UPSs from appendix Y to appendix Y1, ensuring that instructions for all battery chargers are consolidated in one location. Id. at 87 FR 55125–55132. 
On February 2, 2022, DOE initiated a 
rulemaking process to consider amendments to the UPS test procedure by publishing in the Federal Register a 
request for information (‘‘RFI’’) seeking data and information regarding the existing DOE test procedure for UPSs (‘‘February 2022 RFI’’). 87 FR 5742. On May 11, 2022, DOE issued a correcting amendment to address an error in describing input dependency modes in the regulatory text as it appeared in the December 2016 Final Rule. 87 FR 28755. 
DOE received comments in response 
to the February 2022 RFI from the interested parties listed in Table I.1.

7Plug designations are as specified in American 
National Standards Institute (‘‘ANSI’’)/NEMA WD 
6–2016, incorporated by reference at 10 CFR 430.2. 
8DOE defines a ‘‘back-up battery charger’’ as a 
battery charger excluding UPSs: (1) that is embedded in a separate end-use product that is designed to continuously operate using mains power (including end-use products that use external power supplies); and (2) whose sole purpose is to recharge a battery used to maintain continuity of power in order to provide normal or partial operation of a product in case of input power failure. 10 CFR 430.2. More broadly, DOE defines a ‘‘battery charger’’ as a device that charges batteries for consumer products, including battery chargers embedded in other consumer products. Id. 
9Section 1 of appendix Y (‘‘Scope’’) states that 
the appendix does not provide a method for testing back-up battery chargers. 
10For example, DOE has identified the following 
inexhaustive list of portable power stations models in the battery charger CCD: Jackery 550, DEWALT DXAEPS14, STANLEY J5C09, Anker A1710, Duracell PPS1000–1050–120–01. 11Section 1 of appendix Y specifies that this 
appendix provides the test requirements used to measure the energy efficiency of UPSs that utilize the standardized NEMA plug, 1–15P or 5–15P, as specified in ANSI/NEMA WD 6–2016 (incorporated by reference, see § 430.3) and have an AC output. Electrical Manufacturer Association 
(‘‘NEMA’’) plug, 1–15P or 5–15P,7and 
have an alternating current (‘‘AC’’) output. Appendices Y and Y1, section 1. 
In the February 2022 RFI, DOE sought 
comment on whether the scope of the test procedure as it pertains to UPSs is still appropriate or whether DOE should consider any changes in scope. 87 FR 5742, 5744. 
NEMA commented that it did not see 
any need for changes to the UPS test procedure with regards to scope. (NEMA, No. 2 at p. 2) 
Conversely, the Joint Commenters 
recommended that DOE investigate opportunities to expand the scope of the UPS test procedure to cover back-up battery chargers such as portable power systems. (Joint Commenters, No. 3 at p. 1) The Joint Commenters stated that portable power systems are an emerging class of products that are becoming increasingly common for homes given the need for back-up power in climate emergencies and power outage situations. (Id.) The Joint Commenters encouraged DOE to consider incorporating such products into the scope of the test procedure given the substantial potential for growth of these products in the market. (Id.) 
NEEA similarly encouraged DOE to 
expand the scope of the battery charger test procedure to include portable power stations that utilize batteries and to test them using the appendix Y battery charger test instructions. (NEEA, No. 5 at p. 7) NEEA stated that its research reveals that consumer portable power stations are experiencing rapid market adoption. (Id.) NEEA provided examples of products with a range of battery capacities and charge with a home wall outlet. (Id.) NEEA described the primary consumer use for such products as providing emergency home power—which NEEA asserted is a growing need due to the increased frequency of electrical power outages associated with extreme weather conditions—as well as outdoor recreation applications. (Id. at p. 8) 
NEEA stated that consumer portable 
power systems appear to be excluded by DOE’s current test procedure, given that they are not strictly UPSs and may be considered within the definition of ‘‘backup battery chargers,’’
8which are explicitly omitted from the scope of 
appendix Y.9(Id.) Additionally, NEEA 
stated that it was not able to identify portable power stations listed in DOE’s battery charger or UPS compliance certification database (‘‘CCD’’). (Id.) 
However, NEEA stated that its 
technical research supported addressing consumer portable power stations within the non-UPS portion of the test procedure and not the UPS portion because (1) they supply loads when not connected to the grid, whereas the UPS test procedure focuses on the efficiency of a continuously grid-connected system; (2) they have a variety of duty cycles, such that the variety of use scenarios is like other consumer chargers covered by the non-UPS portion of the test procedure; and (3) they have different charge rates, and the 
battery charger test procedure already accommodates variations in charge rates. (Id. at pp. 8–9) 
Relevant to consideration of these 
comments, the scope of DOE’s battery charger test procedure includes all battery chargers operating at either direct current (‘‘DC’’) or United States AC line voltage (115V at 60Hz). Appendix Y, section 1. To the extent that a portable power system meets the definition of a battery charger, operates on DC or United States AC line voltage, but does not meet the definition of a back-up battery charger as defined by DOE, such a product is currently covered within the scope of the non- UPS portion of the battery charger test procedure. Based on the descriptions of products described by NEEA, DOE tentatively concludes that such products may not meet the definition of ‘‘back-up battery charger’’ because they are not embedded in a separate end-use product. Rather, the power station itself is the end-use product and is not used to maintain power in the event of mains power failure. In contrast to NEEA’s findings, DOE has identified—based on a review of product literature—a wide range of portable power stations currently certified as non-UPS battery chargers and listed in the CCD,
10 
suggesting that manufacturers have determined that such products meet these criteria and are therefore covered 
within the scope of the non-UPS portion of the battery charger test procedure. Because such products are already included within the scope of the non- UPS battery charger test procedure, DOE has tentatively determined that no changes are warranted to the scope of the UPS test procedure with respect to such products. 
To the extent that a portable power 
station meets DOE’s definition of a back- up battery charger, such a product is currently outside the scope of appendices Y and Y1. As suggested by NEEA, DOE tentatively agrees that the operational characteristics of portable power stations that are not back-up battery chargers are in the scope of the non-UPS portion of the appendices Y and Y1 test procedure and not the UPS portion. Therefore, changes to the non- UPS portion of appendices Y and Y1 are outside the scope of this rulemaking and DOE is not proposing any changes to the UPS portion of appendices Y and Y1 to address such products. 
The CA IOUs noted that the current 
scope of the UPS test procedure is limited to UPSs that use standard NEMA 1–15P/5–15P wall plugs
11and 
recommended that DOE review current shipments of UPS and UPS-like products to determine if the current method for limiting scope still provides sufficient coverage for this product category. (CA IOUs, No. 4 at pp. 1–2) The CA IOUs stated that they have identified a range of whole-home backup and portable outdoor power delivery devices that are UPS-like, which may offer the potential for energy savings. (Id. at p. 2) According to the CA 
IOUs, shipments of these two products have rapidly expanded since DOE’s previous rulemaking for the UPS product category. (Id.) The CA IOUs commented that these products are currently outside the scope of DOE’s test procedure either because they cannot use NEMA 1–15P/5–15P wall plugs (e.g., whole-home backup products), or 
they typically do not use NEMA 1–15P/ 5–15P wall plugs when in service (e.g., 
portable power stations). (Id.) 
DOE’s initial review of the market for 
the types of products discussed by the CA IOUs confirms the CA IOUs’ findings that such products either do not appear to meet the definition of a UPS and/or do not use NEMA 1–15P/5– 15P wall plugs. In addition, DOE tentatively determines that the test

12DOE notes that use of NEMA 1–15P/5–15P wall 
plugs, as specified by the currently defined scope 
for UPSs, implies the use of AC input power. 
13The comment from NEMA included a duplicate 
section regarding VFI UPS definitions. Based on the context of the discussion throughout NEMA’s comments, DOE presumes that NEMA intended to also include voltage and frequency dependent (‘‘VFD’’) UPSs among the suggested definitions for harmonization with IEC 62040–3 Ed. 3.0. 14Section 2.27.1 of appendices Y and Y1 defines 
VFD UPS as a UPS that produces an AC output where the output voltage and frequency are dependent on the input voltage and frequency. This UPS architecture does not provide corrective functions like those in voltage independent and voltage and frequency independent systems. The definition also includes a Note specifying that VFD 
input dependency may be verified by performing the AC input failure test in section 6.2.2.7 of IEC 62040–3 Ed. 2.0 and observing that, at a minimum, the UPS switches from normal mode of operation to battery power while the input is interrupted. 
15Section 2.27.2 of appendices Y andY1 defines 
VFI UPS as a UPS where the device remains in normal mode producing an AC output voltage and frequency that is independent of input voltage and frequency variations and protects the load against adverse effects from such variations without depleting the stored energy source. The definition also includes a Note specifying that VFI input 
dependency may be verified by performing the steady state input voltage tolerance test and the input frequency tolerance test in sections 6.4.1.1 and 6.4.1.2 of IEC 62040–3 Ed. 2.0, respectively, and observing that, at a minimum, the UPS produces an output voltage and frequency within the specified output range when the input voltage is varied by ±10 percent of the rated input voltage and the input frequency is varied by ±2 percent of the rated input frequency. 
16Section 2.27.3 of appendices Y and Y1 defines 
VI UPS as a UPS that produces an AC output within a specific tolerance band that is independent of under-voltage or over-voltage variations in the input voltage without depleting the stored energy source. The output frequency of a VI UPS is dependent on the input frequency, similar to a voltage and frequency dependent system. The definition also includes a Note specifying that VI input 
dependency may be verified by performing the steady state input voltage tolerance test in section 6.4.1.1 of IEC 62040–3 Ed. 2.0 and ensuring that the UPS remains in normal mode with the output voltage within the specified output range when the input voltage is varied by ±10 percent of the rated input voltage. 
17Section 5.3.4.2.2 of IEC 62040–3 Ed. 3.0 
specifies that a UPS classified as VFD shall protect the load from a complete loss of AC input power. The output of the VFD UPS is dependent on changes in voltage and frequency of the AC input power and is not intended to provide additional voltage corrective functions, such as those arising from the use of tapped transformers. VFD classification is verified when performing the test described in section 6.2.2.7. 
18Section 5.3.4.2.3 of IEC 62040–3 Ed. 3.0 
specifies that a UPS classified VI shall protect the load as required for VFD and also from under- voltage applied continuously to the input, and over- voltage applied continuously to the input. The output voltage of the VI UPS shall remain within declared voltage limits (provided by voltage corrective functions, such as those arising from the use of active and/or passive circuits). The manufacturer shall declare an output voltage tolerance band narrower than the input voltage tolerance band. VI classification is verified when performing the tests described in section 6.4.1.2. The definition also includes a Note specifying that 
the energy storage device does not discharge when the AC input power is within the input voltage tolerance band. 
19Section 5.3.4.2.4 of IEC 62040–3 Ed. 3.0 
specifies that a UPS classified VFI is independent of AC input power voltage and frequency variations conditions specified by the current UPS 
test procedure would not provide a representative measure of energy use or energy efficiency for such products. However, DOE has tentatively determined that the markets for whole- home backup devices and portable outdoor power delivery devices are still nascent, albeit growing, and currently lack widespread use among consumers. DOE is concerned that defining such technologies and addressing them in the UPS test procedure at this time could potentially restrict the development of these less mature technologies. Furthermore, DOE does not have sufficient consumer usage data, nor have commenters provided any such information, that would be needed at this time to develop a test procedure that produces representative results for these products. For these reasons, DOE is not proposing to expand the scope of the UPS test procedure to include whole-home backup power systems or outdoor power delivery devices. 
B. Definitions 
As discussed, DOE defines a UPS as 
a battery charger consisting of a 
combination of convertors, switches, and energy storage devices (such as batteries), constituting a power system for maintaining continuity of load power in case of input power failure. Appendices Y and Y1, section 2.27. This definition aligns with the definition of a UPS provided in IEC 62040–3 Ed. 2.0, which is currently incorporated by reference in appendices Y and Y1. 
In the February 2022 RFI, DOE sought 
comment on whether the current definition for a UPS is still appropriate or whether DOE should consider an amended definition. 87 FR 5742, 5744. 
NEMA commented that the definition 
of a UPS should be updated to align with IEC 62040–3 Ed. 3.0. (NEMA, No. 2 at p. 2) Specifically, NEMA recommended amending the UPS definition to read ‘‘. . . maintaining continuity of AC load power in case of 
AC input power failure’’ [emphasis 
added]. (Id.) 
DOE recognizes the benefit of 
harmonizing with the latest versions of industry standards where applicable and appropriate. DOE has tentatively determined that the addition of the term ‘‘AC’’ in the IEC 62040–3 Ed. 3.0 definition is consistent with the range of products that meet the current definition of a UPS and would not change the scope of products subject to the test procedure.
12Therefore, DOE 
proposes to update its definition of a 
UPS to incorporate by reference the definition specified in IEC 62040–3 Ed. 3.0. 
DOE requests comment on its 
proposal to harmonize its definition of a UPS with that of IEC 62040–3 Edition 3.0. Specifically, DOE requests comment on its tentative determination that such harmonization would not affect the current scope of the UPS test procedure. 
NEMA also suggested that DOE adopt 
or harmonize several other definitions from IEC 62040–3 Ed. 3.0, specifically, total harmonic distortion (‘‘THD’’), voltage independent (‘‘VI’’) UPS, and voltage and frequency independent (‘‘VFI’’) UPS.
13(NEMA, No. 2 at pp. 4– 
6) 
Section 2.26 of appendices Y and Y1 
defines THD, expressed as a percent, as the root mean square (‘‘RMS’’) value of an AC signal after the fundamental component is removed and interharmonic components are ignored, divided by the RMS value of the fundamental component. Section 3.5.49 of IEC 62040–3 Ed. 3.0 defines THD as the ratio of the RMS value of the sum of the harmonic components X
hof 
orders 2 to 40 to the RMS value of the fundamental component X
1, and also 
includes a mathematical formula accompanying this descriptive definition. The key difference between the definitions is that DOE refers to the RMS value of the AC signal, whereas the IEC 62040–3 Ed. 3.0 definition more narrowly specifies measuring the RMS value of harmonic components of order 2 through 40. DOE understands that, in measuring the RMS value of a signal, a laboratory would be required to determine the number of harmonics to include within the measurement. By specifying harmonic components of order 2 through 40, DOE tentatively concludes that the IEC definition may provide a more reproducible measurement among different laboratories compared to the current DOE definition, which requires a laboratory to determine which harmonic components to measure. For this reason, DOE proposes to update its definition of THD to incorporate by reference the definition specified in IEC 62040–3 Ed. 3.0. DOE has carefully reviewed its 
definitions of VFD UPS,
14VFI UPS,15 
and VI UPS16in comparison to the 
definitions provided in sections 5.3.4.2.2,
175.3.4.2.3,18and 5.3.4.2.4,19

as specified and declared in section 5.2 and shall 
protect the load against adverse effects from such variations without discharging the energy storage device. VFI classification is verified when performing the tests described in section 6.4.1.3. respectively, of IEC 62040–3 Ed. 3.0. 
The IEC definitions closely align with the core capabilities described by the DOE definitions. However, DOE’s definitions each include a ‘‘Note’’ that provides greater specificity regarding certain product characteristics than the definitions provided by IEC 62040–3 Ed. 3.0. For example, the Note to section 2.27.2 of appendices Y and Y1 (providing the definition for VFI UPS) specifies that, at a minimum, the VFI UPS produces an output voltage and frequency within the specified output range even when the input voltage is varied by ±10 percent of the rated input voltage and the input frequency is varied by ±2 percent of the rated input frequency. Whereas the definition of VFI UPS in IEC 62040–3 Ed. 3.0 specifies the AC input power voltage tolerance bands to be the greater of ±10 percent of the rated input voltage and what is declared by the manufacturer and the AC input power frequency to be the greater of ±2 percent of the rated input frequency and what is declared by the manufacturer. Similarly, the Note to section 2.27.3 of appendices Y and Y1 (providing the definition for VI UPS) specifies an input voltage variation of ±10 percent, whereas the corresponding definition in IEC 62040–3 Ed 3.0 specifies the voltage limits to be the greater of ±10 percent of the rated input voltage and what is declared by the manufacturer. 
DOE notes that there are scenarios 
where using the manufacturer declared limits may result in a different input dependency classification of a UPS when compared to that conducted using DOE’s current input voltage tolerance limits. For example, a manufacturer that declares an input voltage tolerance limit of ±15 percent for a VI basic model but 
could have a unit that is unable to maintain the required output when the input voltage is adjusted by more than 13 percent in real world testing. Per the IEC definition, this unit would fail the VI input dependency at the manufactured declared limits of ±15 percent and therefore be classified as a VFD UPS (the highest input dependent UPS topology). However, the same unit when tested per DOE’s current input voltage limits of ±10 percent would continue to classify it as a VI. 
To avoid such discrepancies, DOE 
proposes to harmonize its definitions of VFD UPS, VI UPS, and VFI UPSs with IEC 62040–3 Ed 3.0 but maintain the notes alongside each definition that currently establish the input voltage and 
frequency tolerance limits of ±10 percent and ±2 percent, respectively. 
DOE notes that the section numbers of 
IEC 62040–3 Ed. 2.0 currently referenced by DOE’s definitions have been updated to different section numbers in IEC 62040–3 Ed. 3.0. DOE proposes to update its definitions of VFD UPS, VI UPS, and VFI UPS to reference the corresponding updated section numbers within IEC 62040–3 Ed. 3.0. 
DOE has initially determined that the 
proposed amended definitions would not substantively change the scope or applicability of the test procedure as compared to the current definitions. 
DOE requests comment on its 
proposal to update its definitions of THD, VFD UPS, VI UPS, and VFI UPC to harmonize with the IEC 62040–3 Ed 3.0 definitions. 
C. Updates to Industry Standards 
As discussed, the current UPS test 
procedure incorporates by reference 
certain sections of IEC 62040–3 Ed. 2.0 regarding test setup, input and output power measurement, and the optional determination of UPS architecture. Specifically: 
•The definitions of VFD UPS, VFI 
UPS, and VI UPS in sections 2.27.1 through 2.27.3 of appendices Y and Y1 reference: (1) the AC input failure test in section 6.2.2.7 of IEC 62040–3 Ed. 2.0, which in turn references section 5.3.4 and Annex G of IEC 62040–3 Ed. 2.0; (2) the steady state input voltage tolerance test in section 6.4.1.1 of IEC 62040–3 Ed. 2.0, as a subsection to section 6.4.1, which in turn references sections 5.2.1 and 5.2.2.k of IEC 62040– 3 Ed. 2.0; and (3) the input frequency tolerance test in section 6.4.1.2 of IEC 62040–3 Ed. 2.0, which in turn references sections 5.3.2.d and 5.3.2.3 of IEC 62040–3 Ed. 2.0. 
•Section 4.2.1 of appendices Y and 
Y1 specifies configuring the UPS according to Annex J.2 [of Annex J] of IEC 62040–3 Ed. 2.0. 
•Section 4.3.3 of appendices Y and 
Y1 specifies measuring input and output power according to section J.3 of Annex J of IEC 62040–3 Ed. 2.0. 
Since publication of the December 
2016 Final Rule, IEC has updated the IEC 62040–3 standard to its third edition (i.e., IEC 62040–3 Ed. 3.0). The 
following paragraphs summarize the key changes from the second edition, based on DOE’s initial review of the revised standard. 
Section 4 of IEC 62040–3 Ed. 3.0 
includes updates to various environmental conditions, such as the general test environment and operating conditions when testing UPSs. 
Appendices Y and Y1, however, do not refer to section 4 of the IEC 62040–3 standard but instead provide their own environmental and operating conditions for testing purposes. DOE has therefore determined that its test procedure for measuring the efficiency of UPSs will remain unaffected by the updates to section 4 of the IEC 62040–3 Ed. 3.0. 
Section 5.2 of IEC 62040–3 Ed. 2.0 
addresses UPS input specifications, such as the input voltage range, input frequency range, and total harmonic distortions during which the UPS under test must remain in the normal mode of operation. While an initial review of IEC 62040–3 Ed. 3.0 shows significant editorial changes to the sections that define these parameters, the remainder of the parameters remain unchanged. Similarly, section 5.3 of IEC 62040–3 Ed. 3.0 provides the minimum output specifications for UPSs that must be declared by manufacturers, such as its input dependency, rated output voltage and RMS output voltage tolerance band, rated frequency tolerance band, rated output active and apparent power, total harmonic distortion, etc. As before, the majority of the changes to this section are editorial or a reorganization. 
Section 6 of IEC 62040–3 Ed. 2.0 
previously provided instructions for performing the AC input failure test (section 6.2.2.7), the steady-state input voltage tolerance test (section 6.4.1.1), and the input frequency tolerance test (section 6.4.1.2) that are used to classify the input dependency of a UPS as VI, VFD, or VFI. IEC 62040–3 Ed. 3.0 has since updated these subsections with the following changes: subsection titles and numbering have been updated to specifically refer to them as VI, VFD, and VFI input dependency tests; additional criteria have been added for meeting the VI, VFD, and VFI classifications; and a new test load condition at 0 percent (i.e., no-load) has 
been added (see section III.E of this document for further discussion of a no- load test). 
Additional updates to Annex J to IEC 
62040–3 Ed. 3.0 require multi-mode UPSs to be tested at all dependency modes, whereas DOE’s current test procedure explicitly requires UPSs to be tested at only their highest and lowest input dependency modes. Annex J has 
also been updated to allow manufacturers to test UPSs with functions or ports set to the lowest power-consuming mode or disconnected if they are not related to maintaining the energy storage device (i.e., batteries) at full charge, along with 
added reporting requirements for manufacturers to report these features,

turned off or set to the lowest power- consuming mode. This updated clarification regarding additional features is similar to DOE’s current test procedure, which requires UPSs to be tested with such features off or disconnected; however, DOE currently does not require manufacturers to report these manually switched-off features. 
In the February 2022 RFI, DOE 
requested comment on the updates made to IEC 62040–3 Ed. 3.0 and on whether DOE should revise all or parts of its incorporation by reference to harmonize with these changes. 87 FR 5742, 5745. DOE also requested feedback on whether any of the specific updates found in the new IEC standard has the potential to alter the recorded efficiency of UPSs as currently measured by appendix Y. Id. 
DOE received several comments 
regarding aligning its reporting requirements for UPSs with the requirements in the revised Annex J in IEC 62040–3 Ed. 3.0 in response to the February 2022 RFI. The Joint Commenters, NEEA, and NEMA all requested that DOE require manufacturers to report which (if any) additional functionality was switched off for testing. (Joint Commenters, No. 3 at p. 2; NEEA, No. 5 at p. 7; NEMA, No. 2 at p. 4). NEMA commented that adding free text fields in the certification database spreadsheet template would reduce the reporting burden of uploading additional supplementary documentation to provide this information. (NEMA, No. 2 at p. 4) Additionally, NEEA noted that collecting this information increases stakeholder transparency and provides DOE with useful information for future analyses. (NEEA, No. 5 at p. 7) 
DOE is not proposing to amend the 
certification or reporting requirements for UPSs in this NOPR. Instead, DOE may consider proposals to amend the certification requirements and reporting for UPSs under a separate rulemaking regarding appliance and equipment certification. 
In response to the February 2022 RFI, 
NEMA suggested that DOE incorporate the 15-minute accumulated energy measurement method found in Annex J of IEC 62040–3 Ed. 3.0, commenting that it is the measurement method favored by DOE because DOE already includes such a method in appendices Y and Y1. (NEMA, No. 2 at p. 2) NEMA also recommended that DOE incorporate sections 5.2 and 5.3 of IEC 62040–3 or the entire standard and stated that doing so would not alter the measured efficiency of UPSs. (Id. at p. 3) DOE has carefully reviewed IEC 
62040–3 Ed. 3.0 as it relates to 
measuring the efficiency of a UPS. DOE has tentatively determined that the relevant updates to IEC 62040–3 Ed. 3.0 compared to IEC 62040–3 Ed. 2.0 are largely editorial, including renumbering of certain sections referenced by the DOE test procedure, and that updating DOE’s existing references to IEC 62040– 3 Ed. 3.0 would not alter the measured efficiency of basic models. As a result, DOE proposes to update its incorporation by reference of IEC 62040–3 Ed. 2.0 to IEC 62040–3 Ed. 3.0 in 10 CFR 430.3 and to update its references in appendices Y and Y1 accordingly to reflect the renumbering of sections in IEC 62040–3 Ed. 3.0. 
As stated by NEMA in its written 
comment, DOE’s existing test procedure for UPSs already allows recording of either instantaneous power or accumulated energy over a 15-minute period. DOE’s review of Annex J in IEC 62040–3 Ed. 3.0 did not reveal any additional instructions that would further facilitate the use of the accumulated energy method. As such, DOE is not proposing any changes to its existing language in section 4.3.3 of appendices Y and Y1. 
DOE requests comment on its 
proposal to incorporate by reference IEC 62040–3 Ed 3.0 and to update references in appendices Y and Y1 accordingly to reflect the renumbering of sections in IEC 62040–3 Ed 3.0. 
D. Loading Conditions 
Section 4.3.3 of appendices Y and Y1 
requires that the efficiency of a UPS be 
measured at 100, 75, 50, and 25 percent of the device’s rated output power. Each of these measured efficiencies is weighted according to values provided in Table 4.3.1 of appendices Y and Y1 and combined to determine a single weighted average output metric (i.e., the 
average load adjusted efficiency) representing the UPS’s overall efficiency. These load conditions and weightings were established in the December 2016 Final Rule consistent with the load weightings specified in ENERGY STAR UPS Specification Version 1.0.
2081 FR 89806, 89816. The 
current ENERGY STAR UPS Specification Version 2.0
21maintains 
these same load conditions and weightings. These load conditions and weightings are also consistent with those specified in section 6.4.1.6 of IEC 62040–3 Ed. 2.0 and section 6.4.1.9 of IEC 62040–3 Ed. 3.0. 
In the February 2022 RFI, DOE 
requested comment on whether the UPS load weightings specified in Table 4.3.1 are representative of current UPS usage patterns. 87 FR 5742, 5746. DOE also requested data on the consumer usage profile of UPSs with respect to each architecture (i.e., VFD, VI, and VFI). Id. 
NEEA, the Joint Commenters, and the 
CA IOUs all recommended introducing a fifth loading test condition at 10 percent of the device’s rated output power, asserting that such a loading condition is more representative of desktop computers and other loads typically protected by UPSs. They further asserted that adding a 10-percent loading condition to UPS testing, along with a revised load weighting, would provide a more accurate efficiency value. (NEEA, No. 5 at pp. 1–4; Joint Commenters, No. 3 at pp. 1–2; CA IOUs, No. 4 at pp. 2–3) 
NEMA, however, advised against 
adding a 10-percent loading condition and adjusting the loading level weights without significant evidence to support making such adjustments, arguing that DOE should maintain harmonization with IEC 62040–3 Ed. 3.0. NEMA further asserted that additional load test points are mathematically unnecessary and would invalidate testing already performed, which would impose a significant burden on manufacturers with no tangible benefits. NEMA further commented that mathematical loss models can be used to accurately predict UPS efficiency at any load point based on the five measurements already required by the DOE test procedure. (NEMA, No. 2 at p. 6) 
As discussed, EPCA requires that any 
test procedures prescribed or amended under this section be reasonably designed to produce test results that measure energy efficiency, energy use, or estimated annual operating cost of a 
covered product during a representative average use cycle or period of use, and not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3)) As such, DOE must weigh the representativeness of test results with the associated test burden in evaluating any amendments to its test procedures. Regarding the representativeness of the DOE test procedure, the commenters have not provided specific data, nor is DOE aware of any specific data, demonstrating that a 10-percent loading condition would produce a more representative measure of energy use or energy efficiency of UPSs. In addition,

22The European Union Code of Conduct on 
Energy Efficiency and Quality of AC UPSs Version 
2.0 is available at e3p.jrc.ec.europa.eu/publications/ code-conduct-energy-efficiency-and-quality-ac- uninterruptible-power-systems-ups-0. 23The Joint Commenters cited DOE’s battery 
charger test procedure NOPR published November 23, 2021. 86 FR 66878. DOE subsequently published a battery charger test procedure final rule on September 8, 2022, which includes a maintenance mode test for battery chargers. 87 FR 55090. 24IEC 62040–3 Ed 3.0 defines a linear load as a 
load wherein the load impedance is a constant. 
25IEC 62040–3 Ed 3.0 defines a non-linear load 
as a load wherein the load impedance is a variable dependent on other parameters, such as voltage or time. 
26IEC 62040–3 Ed. 2.0 defines ‘‘reference test 
load’’ as a load or condition in which the output of the UPS delivers the active power (W) for which the UPS is rated. DOE’s test procedure does not 
differentiate between specific end-use applications. Therefore, load profiles specific to certain applications (e.g., desktop computers) may not be representative of overall average use of UPSs across all end-use applications. Further, were DOE to consider a 10- percent load condition, DOE is not aware of any data to suggest what corresponding weighting factor should be used to combine this loading condition with the other defined loading conditions comprising the overall efficiency metric. 
Regarding test burden, as noted, the 
loading points currently specified in appendices Y and Y1 are consistent with the loading points defined by ENERGY STAR, as well as section 6.4.1.6 of IEC 62040–3 Ed. 3.0. DOE also notes that the requirements of IEC 62040–3 Ed. 3.0 are referenced by the European Union Code of Conduct on Energy Efficiency and Quality of AC UPSs Version 2.0.
22Like many other 
types of consumer electronics, UPSs are manufactured and distributed globally by multi-national suppliers; as such, any differences between the DOE test procedure (applicable to products sold or imported into the United States) and internationally-recognized industry test methods impose a burden that is acutely impactful to the consumer electronics industry. 
Having weighed the potential 
improvement to representativeness against the potential for increased test burden associated with adding a required 10-percent loading condition that would be applicable to all UPSs, DOE has tentatively concluded—based on information currently available—that the potential burden would outweigh any potential improvement in representativeness; i.e., would introduce 
undue test burden. Consequently, DOE is not proposing to modify its existing loading points, weightings, or overall efficiency metric in this NOPR. 
DOE requests comment on its 
proposal to not modify the existing loading points, weighting, or the overall efficiency metric in the current UPS test 
procedure. 
E. No-Load Test 
DOE’s test procedure for UPSs does 
not currently specify a method for 
determining the energy consumption of a UPS at no-load (i.e., 0 percent loading 
condition). As discussed in section III.C of this NOPR, IEC 62040–3 Ed. 3.0 adds a new test load condition at 0 percent 
(i.e., no-load) at section 6.4.1.10. In 
addition, ENERGY STAR UPS Specification Version 2.0 specifies testing at a 0-percent load condition, and the resulting power measurement (in Watts) is one of the required reported values. In the February 2021 RFI, DOE requested information on whether incorporating the additional no-load test has the potential to cause currently reported UPS input- dependency classifications to change. 
In response to the February 2022 RFI, 
the Joint Commenters recommended that DOE incorporate the no-load test condition into its UPS test procedure and establish a separate standby mode metric based on the no-load test condition. The Joint Commenters asserted that a standby mode measurement at the no-load test condition would provide consumers with a more accurate understanding of UPS energy consumption and would align DOE’s UPS test procedure more closely with DOE’s external power supply (‘‘EPS’’) and battery charger test procedures. The Joint Commenters asserted that the no-load condition of a UPS aligns closely with battery charger maintenance mode—in which a battery charger is connected to a battery and provides some limited charging in order to maintain the battery at full charge— and that because DOE determined that battery charge maintenance mode qualifies under EPCA’s definition of standby mode,
23that it would be 
appropriate for DOE to establish a standby metric for UPSs based on the 
no-load test condition. (Joint Commenters, No. 3 at p. 3) 
NEEA also encouraged DOE to add a 
no-load test condition to the UPS test procedure. NEEA asserted that UPSs operate at no-load or low-load when attached equipment, such as desktop computers, are powered off or running in sleep or idle modes; that relevant studies suggest that desktop computers spend much of their time powered off or in sleep or idle modes; and that the substantial differences in no-load input power across UPS models suggest a significant energy savings opportunity. (NEEA, No. 5 at pp. 1–2) Based on its analysis of cited research, NEEA concluded that a no-load condition would effectively represent desktop computer off and sleep modes. (Id. at 2) 
NEEA encouraged DOE to require reporting of UPS no-load power draw separately from the current active mode efficiency because the no-load measurement would be a power value rather than a percent efficiency, and that such an approach would harmonize with DOE’s no-load approach for EPSs, battery chargers, and ENERGY STAR’s approach for UPSs. (NEEA, No. 5 at pp. 4–5) 
DOE recognizes the usefulness of a 
no-load power consumption metric to the industry and stakeholders, as evidenced by the inclusion of a no-load test in IEC 62040–3 Ed. 3.0, its inclusion as a reporting requirement for the ENERGY STAR UPS Specification Version 2.0, and comments from interested parties in response to the February 2021 RFI. For these reasons, DOE proposes to incorporate by reference the no-load test condition specified in section 6.4.1.10 of IEC 62040–3 Ed. 3.0 as a test in section 4.3.3 of appendices Y and Y1 that would be used as the basis for any representations of no-load power consumption. However, DOE notes that manufacturers will not be required to certify no-load power consumption to DOE as a result of this proposal because the energy conservation standards for UPSs do not have a no-load requirement at this time. 
DOE requests feedback on its proposal 
to add a method for measuring the power consumption of UPSs at no-load as a test to be used as the basis for any representations of no-load power consumption. 
F. Reference Test Load 
DOE’s test procedure refers to the 25, 
50, 75, and 100-percent loads as 
‘‘reference test loads.’’ In general, test loads for testing consumer electronics can be either linear
24or non-linear25in 
nature. 
While IEC 62040–3 Ed. 2.0 provides a 
definition for reference test load,26it 
does not explicitly address whether such a test load is linear or non-linear in nature. Section 2.24 of appendices Y and Y1 defines ‘‘reference test load’’ as a load or condition with a power factor of greater than 0.99 in which the AC output socket of the UPS delivers the active power (W) for which the UPS is rated. By specifying a power factor requirement of greater than 0.99, DOE’s

current definition necessitates the use of 
a test load that is both linear and resistive. 
In response to the February 2022 RFI, 
NEEA recommended that to improve the representativeness of the UPS test procedure, DOE should require active mode testing employing the non-linear load specified in Annex E of IEC 62040– 3 Ed. 3.0. NEEA stated that nearly all UPS loads are non-linear (i.e., non- 
resistive) and have a power factor of less than one. NEEA explained that these non-linear loads increase current flows through the UPS, resulting in more losses and producing more heat. NEEA stated that manufacturers design UPSs to account for these types of loads, but that DOE’s test procedure does not currently require non-linear loads in its efficiency measurements. (NEEA, No. 5 at p. 6) 
Section D.2 in Annex D of IEC 62040– 
3 Ed. 3.0 explains that the diversity of types of load equipment and their relevant characteristics are always changing with technology. For this reason, the UPS output performance is characterized by loading with passive reference loads to simulate, as far as practical, the expected load types, but it cannot be taken that these load types are totally representative of the actual load equipment in a given application. The UPS industry has generally specified UPS output characteristics under conditions of linear loading, i.e., resistive or resistive/inductive. The effect on the output of the UPS by non- 
linear loads both in steady state and dynamic is, in many cases, to cause deviation from the output characteristic specified by the manufacturer/supplier where these are quoted under linear load conditions. 
While DOE recognizes that loads 
protected by UPSs can be non-linear, the use of non-linear loads for testing may create certain challenges or difficulties in meeting the specified test conditions, as described within section D.2 of IEC 62040–3 Ed. 3.0. This suggests that testing with non-linear loads may produce results that are less repeatable or reproducible than testing with linear loads. DOE has no information, nor have commenters provided any information, about how the use of non-linear loads for UPS testing may affect repeatability, reproducibility, or test burden. As a result, DOE is not proposing the use of non-linear test loads for testing UPSs at this time. 
G. Error Corrections 
At the time of the February 2022 RFI, 
paragraph (a) of section 4.2.1 of 
appendices Y and Y1, ‘‘UPS Operating Mode Conditions,’’ stated that if the UPS can operate in two or more distinct normal modes as more than one UPS architecture, conduct the test in its lowest input dependency as well as in its highest input dependency mode where VFD represents the lowest [emphasis added] possible input dependency, followed by VI and then VFI. 
NEMA stated that specifying the 
‘‘lowest’’ possible input dependency is a typographical error, and that VFD represents the highest possible input dependency rather than the lowest. (NEMA, No. 2 at p. 3) In a correcting amendment published May 11, 2022, DOE acknowledged that the text in paragraph (a) of section 4.2.1 of appendix Y erroneously identifies VFD as the lowest input dependency, whereas it is in fact the highest input dependency as identified in the referenced Annex J.2 of IEC 62040–3 Ed 2.0. 87 FR 28755, 28755. DOE corrected this error in the text by replacing the erroneous word ‘‘lowest’’ with ‘‘highest.’’ Id. As a result, DOE is not 
proposing any changes to that corrected text in this NOPR. 
H. Test Procedure Costs and 
Harmonization 
1. Test Procedure Costs and Impact 
EPCA requires that test procedures 
proposed by DOE not be unduly 
burdensome to conduct. (42 U.S.C. 6293(b)(3)) In this NOPR, DOE proposes to amend the existing test procedure for UPSs by updating the industry standard incorporated by reference to its latest version, updating definitions consistent with the latest version of the industry standard, and introducing an optional test for measuring the power consumption of UPSs at no-load conditions. DOE has tentatively determined that these proposed amendments would not be unduly burdensome for manufacturers to conduct. 
The proposed update to the latest 
version of the industry standard would not change the method of testing UPSs, but rather would only make non- substantive changes, such as section renumbering. The proposed amendments to harmonize certain definitions with the industry standard would not change the scope of products currently subject to the DOE test procedure or energy conservation standards. And the proposed test procedure for measuring the power consumption of UPSs at no-load conditions would not be required for demonstrating compliance with standards. Therefore, the proposed amendments will not alter the measured 
energy efficiency or energy use of UPSs. Manufacturers will be able to rely on data generated under the current test procedure. Further, the proposed changes would not require the purchase of additional equipment or increase test burden, and consequently would not impact testing costs. If manufacturers elected to continue to make representations or begin making representations regarding UPS power consumption at no-load conditions, they may need to retest the standby power portion of the test procedure for their UPS model. DOE estimates that this retest would cost approximately $1,700 per unit if the test is conducted by a third-party lab and substantially less if done by the manufacturer themselves. However, as stated previously, any representations from such a retest would not be required for demonstrating compliance with standards. 
2. Harmonization With Industry 
Standards 
DOE’s established practice is to adopt 
relevant industry standards as DOE test 
procedures unless such methodology would be unduly burdensome to conduct or would not produce test results that reflect the energy efficiency, energy use, water use (as specified in EPCA), or estimated operating costs of that product during a representative average use cycle or period of use. Section 8(c) of appendix A of 10 CFR part 430 subpart C. In cases where the industry standard does not meet EPCA statutory criteria for test procedures, DOE will make modifications through the rulemaking process to these standards as the DOE test procedure. 
The test procedure for UPSs at 
appendices Y and Y1 currently incorporates by reference IEC 62040–3 Ed. 2.0 regarding test setup, input and output power measurement, and the optional determination of UPS architecture. DOE is proposing to incorporate by reference the latest version of this industry standard (i.e., IEC 62040–3 Ed. 3.0). Additional discussion of this proposed update is provided in section III.B of this document. 
DOE requests comment on the 
benefits and burdens of the proposed updates and additions to the industry standard referenced in the test procedure for UPSs. 
I. Compliance Date 
EPCA prescribes that, if DOE amends 
a test procedure, all representations of 
energy efficiency and energy use, including those made on marketing materials and product labels, must be 
VerDate Sep<11>2014 19:36 Jan 04, 2023 Jkt 259001 PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 E:\FR\FM\05JAP1.SGM 05JAP1ddrumheller on DSK6VXHR33PROD with PROPOSALS799 Federal Register / Vol. 88, No. 3 / Thursday, January 5, 2023 / Proposed Rules 
made in accordance with that amended 
test procedure, beginning 180 days after publication of such a test procedure final rule in the Federal Register. (42 U.S.C. 6293(c)(2)) 
If DOE were to publish an amended 
test procedure, EPCA provides an allowance for individual manufacturers to petition DOE for an extension of the 180-day period if the manufacturer may experience undue hardship in meeting the deadline. (42 U.S.C. 6293(c)(3)) To receive such an extension, petitions must be filed with DOE no later than 60 days before the end of the 180-day period and must detail how the manufacturer will experience undue hardship. (Id.) 
DOE also recognizes that the 
publication of two separate final rules (the September 2022 Final Rule amending the test procedure for battery chargers that are not UPSs and a potential future test procedure final rule for UPSs, if DOE were to publish an amended test procedure) amending the battery charger test procedures at appendix Y could cause confusion as to what version of these appendices is required to be used when making a representation. A further complication is that the September 2022 Final Rule created a new test procedure at appendix Y1 that expanded the scope of the battery charger test method and established a new multi-metric approach for all battery chargers other than UPSs. Manufacturers will be required to continue to use the amended test procedure in appendix Y until the compliance date of amended energy conservation standards for battery chargers established by an energy conservation standard final rule at some point in the future. Only upon the compliance date of amended energy conservation standards for battery chargers will manufacturers be required to begin using the test procedure in appendix Y1. 
The September 2022 Final Rule 
amended appendix Y requiring manufacturers of battery chargers to use this recently updated version beginning March 7, 2023. While the sections in appendix Y that apply to UPSs remained unchanged by the September 2022 Final Rule, UPS manufacturers are required to use the version of appendix Y, as modified by the September 2022 
Final Rule, beginning on March 7, 2023. Because there are no differences in how a UPS is tested between the two versions of appendix Y, DOE tentatively concludes that it would be preferable to refer to the same version of the Appendix (as finalized by the September 2022 Final Rule) for testing both battery chargers and UPSs, even though the UPS testing provisions 
remain unchanged. DOE also concludes that presenting these various compliance dates and references to different versions of the appendices in a tabular format would be more effective. Accordingly, in this NOPR, DOE is proposing to update the notes section at the beginning of appendices 
Y and Y1 to include a table that clearly identifies the appropriate appendix reference and compliance dates for each product. 
IV. Procedural Issues and Regulatory 
Review 
A. Review Under Executive Orders 
12866 and 13563 
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), 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 proposed 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 proposed regulatory action does not constitute a ‘‘significant regulatory action’’ under section 3(f) of E.O. 12866. Accordingly, this action was not submitted to OIRA for review under E.O. 12866. 
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’’) 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 Executive Order 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ 67 FR 53461 (August 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 DOE 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 reviewed 
this proposed rule under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. 
For manufacturers of UPSs, the Small 
Business Administration (‘‘SBA’’) has 
set a size threshold, which defines those entities classified as ‘‘small businesses’’ for the purposes of the statute. DOE used the SBA’s small business size standards to determine whether any small entities would be subject to the requirements of the rule. See 13 CFR 
part 121. The size standards are listed by the North American Industry Classification System (‘‘NAICS’’) code and industry description and are available at www.sba.gov/document/ support--table-size-standards. Manufacturing of UPSs is classified under NAICS 335999, ‘‘All Other Miscellaneous Electrical Equipment and Component Manufacturing.’’ The SBA sets a threshold of 500 employees or less for an entity to be considered as a small business for this category. 
To estimate the number small 
businesses that manufacture UPSs impacted by this rulemaking, DOE conducted a survey using information from DOE’s Compliance Certification Database and previous rulemakings. DOE used information from these 
VerDate Sep<11>2014 19:36 Jan 04, 2023 Jkt 259001 PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 E:\FR\FM\05JAP1.SGM 05JAP1ddrumheller on DSK6VXHR33PROD with PROPOSALS800 Federal Register / Vol. 88, No. 3 / Thursday, January 5, 2023 / Proposed Rules 
sources to create a list of companies that 
potentially manufacture or sell UPSs. DOE screened out companies that do not offer products covered by this rulemaking, do not meet the definition of a ‘‘small business,’’ or are foreign owned and operated. DOE identified five companies that are small businesses manufacturing UPSs covered by this rulemaking. 
However, DOE has tentatively 
concluded that the proposed updates to DOE’s test procedure for UPSs do not involve substantive changes to the test setup and methodology and will not pose any additional test burden or additional test costs for any UPS manufacturers, large or small. 
Therefore, DOE tentatively concludes 
that the impacts of the test procedure amendments proposed in this NOPR would not have a ‘‘significant economic impact on a substantial number of small entities,’’ and that the preparation of an IRFA is not warranted. DOE will transmit the certification and supporting statement of factual basis to the Chief Counsel for Advocacy of the Small Business Administration for review under 5 U.S.C. 605(b). 
C. Review Under the Paperwork 
Reduction Act of 1995 
Manufacturers of UPSs must certify to 
DOE that their products comply with any applicable energy conservation standards. To certify compliance, manufacturers must first obtain test data for their products according to the DOE test procedures, 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 UPSs. (See 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. 
DOE is not proposing to amend the 
certification or reporting requirements for UPSs in this NOPR. Instead, DOE may consider proposals to amend the certification requirements and reporting for UPSs under a separate rulemaking regarding appliance and equipment certification. DOE will address changes to OMB Control Number 1910–1400 at 
that time, as necessary. 
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 
In this NOPR, DOE proposes test 
procedure amendments that it expects will be used to develop and implement future energy conservation standards for UPSs. DOE has determined that this proposed rule falls into a class of actions that are categorically excluded from review under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE’s implementing regulations at 10 CFR part 1021. Specifically, DOE has determined that adopting test procedures for measuring energy efficiency of consumer products and industrial equipment is consistent with activities identified in 10 CFR part 1021, appendix A to subpart D, A5 and A6. Accordingly, neither an environmental assessment nor an environmental impact statement is required. 
E. Review Under Executive Order 13132 
Executive Order 13132, ‘‘Federalism,’’ 
64 FR 43255 (Aug. 4, 1999) imposes 
certain requirements on 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. DOE has examined this proposed 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 prescribes Federal preemption of State regulations as to energy conservation for the products that are the subject of this proposed 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(d)) No further action is required by Executive Order 13132. 
F. Review Under Executive Order 12988 
Regarding the review of existing 
regulations and the promulgation of 
new regulations, section 3(a) of Executive Order 12988, ‘‘Civil Justice Reform,’’ 61 FR 4729 (Feb. 7, 1996), 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. Section 3(b) of Executive Order 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 Executive Order 12988 requires executive agencies to review regulations in light of applicable standards in sections 3(a) and 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, the proposed rule meets the relevant standards of Executive Order 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. Publc Law 104–4, sec. 201 (codified at 2 U.S.C. 1531). For a proposed 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)) 
VerDate Sep<11>2014 19:36 Jan 04, 2023 Jkt 259001 PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 E:\FR\FM\05JAP1.SGM 05JAP1ddrumheller on DSK6VXHR33PROD with PROPOSALS801 Federal Register / Vol. 88, No. 3 / Thursday, January 5, 2023 / Proposed Rules 
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 proposed ‘‘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 small governments. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA. 62 FR 12820; also available at www.energy.gov/gc/office-general- counsel. DOE examined this proposed 
rule according to UMRA and its statement of policy and determined that the rule contains neither an 
intergovernmental mandate, nor a mandate that may result in the expenditure of $100 million or more in any year, so these requirements do not apply. 
H. Review Under the Treasury and 
General Government Appropriations Act, 1999 
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 rule that may affect family well-being. This proposed rule would not have any impact on the autonomy or integrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking Assessment. 
I. Review Under Executive Order 12630 
DOE has determined, under Executive 
Order 12630, ‘‘Governmental Actions 
and Interference with Constitutionally Protected Property Rights,’’ 53 FR 8859 (March 18, 1988), that this proposed regulation would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution. 
J. Review Under 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 agencies to review most disseminations of information to the public under 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 proposed rule under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines. 
K. Review Under Executive Order 13211 
Executive Order 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 OMB, a Statement of Energy Effects for any proposed significant energy action. A ‘‘significant energy action’’ is defined as any action by an agency that promulgated 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 proposed 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. 
The proposed regulatory action to 
amend the test procedure for measuring the energy efficiency of UPSs is not a significant regulatory action under Executive Order 12866. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy, nor has it been designated as a significant energy action by the Administrator of OIRA. Therefore, it is not a significant energy action, and, accordingly, DOE has not prepared a Statement of Energy Effects. 
L. Review Under Section 32 of the 
Federal Energy Administration Act of 1974 
Under section 301 of the Department 
of Energy Organization Act (Pub. L. 95– 91; 42 U.S.C. 7101), DOE must comply with section 32 of the Federal Energy Administration Act of 1974, as amended by the Federal Energy Administration Authorization Act of 1977. (15 U.S.C. 788; ‘‘FEAA’’) Section 32 essentially provides in relevant part that, where a proposed rule authorizes or requires use of commercial standards, the notice of proposed rulemaking must inform the public of the use and background of such standards. In addition, section 32(c) requires DOE to consult with the Attorney General and the Chairman of the Federal Trade Commission (‘‘FTC’’) concerning the impact of the commercial or industry standards on competition. 
The proposed modifications to the 
test procedure for UPSs would incorporate testing methods contained in certain sections of the following commercial standard: IEC 62040–3 Ed. 3.0. DOE has evaluated this standard and is unable to conclude whether it fully complies with the requirements of section 32(b) of the FEAA (i.e., whether 
it was developed in a manner that fully provides for public participation, comment, and review.) DOE will consult with both the Attorney General and the Chairman of the FTC concerning the impact of this test procedure on competition, prior to prescribing a final rule. 
M. Description of Materials 
Incorporated by Reference 
IEC 62040–3 Ed. 3.0, ‘‘Uninterruptible 
power systems (UPS)—Part 3: Method of specifying the performance and test requirements’’ is an industry-accepted test standard that specifies methods for measuring the efficiency of a UPS. The test procedure proposed in this NOPR updates all references from the previous edition (IEC 62040–3 Ed. 2.0) to this most current edition (IEC 62040–3 Ed. 3.0). IEC 62040–3 Ed. 3.0 is readily available from ANSI at webstore.ansi.org. 
In this NOPR, DOE proposes to add a 
new section 0 (Incorporation by Reference) to both appendices Y and Y1 listing the applicable sections of IEC 62040–3 Ed. 3.0 that are referenced by the test procedure.

27DOE has historically provided a 75-day 
comment period for test procedure NOPRs pursuant 
to the North American Free Trade Agreement, U.S.- Canada-Mexico (‘‘NAFTA’’), Dec. 17, 1992, 32 I.L.M. 289 (1993); the North American Free Trade Agreement Implementation Act, Public Law 103– 182, 107 Stat. 2057 (1993) (codified as amended at 10 U.S.C.A. 2576) (1993) (‘‘NAFTA Implementation Act’’); and Executive Order 12889, ‘‘Implementation of the North American Free Trade Agreement,’’ 58 FR 69681 (Dec. 30, 1993). However, on July 1, 2020, the Agreement between the United States of America, the United Mexican States, and the United Canadian States (‘‘USMCA’’), Nov. 30, 2018, 134 Stat. 11 (i.e., the successor to NAFTA), went into 
effect, and Congress’s action in replacing NAFTA through the USMCA Implementation Act, 19 U.S.C. 4501 et seq. (2020), implies the repeal of E.O. 12889 
and its 75-day comment period requirement for technical regulations. Thus, the controlling laws are EPCA and the USMCA Implementation Act. Consistent with EPCA’s public comment period requirements for consumer products, the USMCA only requires a minimum comment period of 60 days. Consequently, DOE now provides a 60-day public comment period for test procedure NOPRs. who is representative of a group or class 
of persons that has an interest in these issues, may request an opportunity to make an oral presentation at the webinar. Such persons may submit to ApplianceStandardsQuestions@ee.doe.gov. Persons who wish to speak 
should include with their request a computer file in WordPerfect, Microsoft Word, PDF, or text (ASCII) file format that briefly describes the nature of their interest in this proposed rulemaking and the topics they wish to discuss. Such persons should also provide a daytime telephone number where they can be reached. 
C. Conduct of the Webinar 
DOE will designate a DOE official to 
preside at the webinar/public meeting 
and may also use a professional facilitator to aid discussion. The meeting will not be a judicial or evidentiary-type public hearing, but DOE will conduct it in accordance with section 336 of EPCA (42 U.S.C. 6306). A court reporter will be present to record the proceedings and prepare a transcript. DOE reserves the right to schedule the order of presentations and to establish the procedures governing the conduct of the webinar/public meeting. There shall not be discussion of proprietary information, costs or prices, market share, or other commercial matters regulated by U.S. anti-trust laws. After the webinar/public meeting and until the end of the comment period, interested parties may submit further comments on the proceedings and any aspect of the rulemaking. 
The webinar will be conducted in an 
informal, conference style. DOE will present a general overview of the topics addressed in this proposed rulemaking, allow time for prepared general statements by participants, and encourage all interested parties to share 
their views on issues affecting this proposed rulemaking. Each participant will be allowed to make a general statement (within time limits determined by DOE), before the discussion of specific topics. DOE will permit, as time permits, other participants to comment briefly on any general statements.

* * * * * 2.26. Total harmonic distortion (THD), 
expressed as a percent, is as defined in section 3.5.49 of IEC 62040–3 Ed. 3.0. 
2.27. Uninterruptible power supply or UPS 
means a battery charger consisting of a combination of convertors, switches and energy storage devices (such as batteries), constituting a power system for maintaining continuity of load power in case of AC input power failure. 
2.27.1. Voltage and frequency dependent 
UPS or VFD UPS means a UPS that protects the load from a complete loss of AC input power. The output of a VFD UPS is dependent on changes in voltage and frequency of the AC input power and is not intended to provide additional voltage corrective functions, such as those arising from the use of tapped transformers. 
Note to 2.27.1: VFD input dependency may 
be verified by performing the AC input failure test in section 6.2.2.7 of IEC 62040– 3 Ed. 3.0 and observing that, at a minimum, the UPS switches from normal mode of operation to battery power while the input is interrupted. 
2.27.2. Voltage and frequency independent 
UPS or VFI UPS means a UPS that is independent of AC input power voltage and frequency variations as specified and declared in section 5.2 of IEC 62040–3 Ed. 3.0 and shall protect the load against adverse effects from such variations without discharging the energy storage device. 
Note to 2.27.2: VFI input dependency may 
be verified by performing the combined input 
voltage/frequency tolerance and VFI input independency test in section 6.4.1.3 of IEC 62040–3 Ed. 3.0 respectively and observing that, at a minimum, the UPS produces an output voltage and frequency within the specified output range when the input voltage is varied by ±10% of the rated input voltage and the input frequency is varied by ±2% of the rated input frequency. 
2.27.3. Voltage independent UPS or VI UPS 
means a UPS that protects the load as required for VFD and also from (a) under- voltage applied continuously to the input, and (b) over-voltage applied continuously to the input. The output voltage of a VI UPS shall remain within declared voltage limits (provided by voltage corrective functions, such as those arising from the use of active and/or passive circuits). The output voltage tolerance band shall be narrower than the input voltage tolerance band. Note to 2.27.3: VI input dependency may 
be verified by performing the steady state input voltage tolerance test in section 6.4.1.2 of IEC 62040–3 Ed. 3.0 and ensuring that the UPS remains in normal mode with the output voltage within the specified output range when the input voltage is varied by ±10% of the rated input voltage.
