## CHAPTER 1



# INTRODUCTION

Background

The Tennessee Valley Authority (TVA) has contracted with Global Energy Partners (Global) to

conduct a potential study to assess 20-year pote ntials for energy efficiency (EE) and demand

response (DR). TVA has an aspirational goal to lead the southeast in energy efficiency, and

believes this leadership can be accomplished through the development and implementation of

action plans for EE, DR, and end-use generation. Th is potential study will provide information to

assist TVA in meeting that goal.

Toward this end, Global conducted a detaile d, bottom-up assessment of the TVA market to

deliver forecasts of energy use and peak demand, as well as forecasts of energy and peakdemand savings achievable through energy ef ficiency and demand response programs. The 20-

year potentials study addresses the residential, small commercial, large commercial, and

industrial sectors. Results of this task are di scussed in two volumes, one for energy efficiency

and one for demand response, as described below in the report organization.

Global also compared the results of the potential savings to those from existing regional potential

studies that are specific to the Southeast and other select studies. This analysis, which appears

in both the energy efficiency and demand resp onse reports, also compares these potential

studies with regard to methodology, assumpti ons, approaches, estimated baselines, technical

performance, adoption, and pr ogram/regulatory context.

This document is Volume 1: Executive Summary, an overview of the entire energy efficiency

and demand response analysis. The other volumes are:

• Volume 2, Energy Efficiency Potential

• Volume 3, Demand Response Potential



# Objectives

Key objectives for the study include:

• Conduct a 20-year bottom-up energy efficiency po tential study to determine the potential for

specific energy efficiency measures to reduce the consumption and peak demand of

electricity in the TVA service territory.

• Conduct a demand response potential study to determine the potential for reduction in peak

demand through demand response programs.

• Compare the potential study results with other national and regional studies, including details

regarding assumptions used to develop each of the studies.



# Definitions of Potential

In this study, we estimate the potential for energy efficiency savings. The savings estimates

represent gross savings 1 

## developed into three types of potential: technical potential, economic

potential, and achievable potential. Technical an d economic potential are both theoretical limits

to efficiency savings. Achievable potential em bodies a set of assumpti ons about the decisions

1 Savings in “gross” terms instead of “net” terms means that the baseline forecast does not include naturally occurring efficien cy. In

other words, the baseline assumes that energy efficiency levels re main fixed as they are today. This rule holds true except in cases

where enactment of future codes and standards were on the b ooks before January 2011, e.g., the effects of the EISA 2007 lightin g

efficiency standard.TVA Energy Efficiency Potential Study, Volume 1 Introduction

1-2 www.gepllc.com 

## consumers make regarding the efficiency of th e equipment they purchase, the maintenance

activities they undertake, the controls they use for energy-consuming equipment, and the

elements of building construction. For this reason , we developed a range of achievable potential.

These levels are described below.

Technical potential is defined as the theoretical upper limit of energy efficiency potential. It

assumes that customers adopt all feasible measur es regardless of their cost. At the time of

equipment failure, customers replac e their equipment with the most efficient option available. In

new construction, customers and developers also choose the most efficient equipment option.

Examples of measures that make up technical potential in the residential sector include:

• Ductless mini-split air conditioners with variable refrigerant flow

• Ground source (or geothermal) heat pumps

• LED lighting

Technical potential also assumes the adoption of every available other measure, where

applicable. For example, it includes installation of high-efficiency windows in all new construction

opportunities and air conditioner maintenance in al l existing buildings with central and room air

conditioning. The retrofit measures are phased in over a number of years, which is longer for

higher-cost measures.

Economic potential represents the adoption of all cost-effective energy efficiency measures.

In this analysis, the total resource cost (TRC) te st, which compares lifetime energy and capacity

benefits to the incremental cost of the measure, is applied. Economic potential assumes that

customers purchase the most cost-effective opti on at the time of equi pment failure and also

adopt every other cost-effecti ve and applicab le measure.

Achievable - High potential takes into account expected program participation resulting from

ideal implementation conditions and customer preferences for energy-efficient technologies and

demand response programs. Achievable - High es tablishes a maximum target for the EE savings

that a utility can hope to achieve through its EE programs and involves incentives that represent

a substantial portion of the incremental cost co mbined with high administrative and marketing

costs.

Achievable - Low potential represents a lower bound on Achievable potential. It reflects

limited DSM budgets and significant barriers to customer acceptance.Global Energy Partners 2-1

## CHAPTER 2



# ENERGY EFFICIENCY POTENTIAL

Analysis Approach

To perform the energy efficiency analysis, Global used a bottom-up analysis approach as shown

in Figure 2-1. We took the following steps:

1. Held a meeting with the project team to refine th e objectives that were identified in the TVA

RFP. This resulted in a work plan for the study.

2. Performed a market characterization to desc ribe sector-level electricity use for the

residential, commercial, and industrial sectors for the base year, TVA 2009. (Note that all

years referred to in this report are TVA fiscal years). This included using utility data and

secondary data from sources such as the Am erican Community Survey (ACS) and the Energy

Information Administration (EIA).

3. Utilized TVA primary market research (such as TVA’s 2010 residential market saturation

survey) and secondary sources to understan d how customers in the Tennessee Valley

currently use electricity. Combining this information with the market characterization, we

developed energy market profiles that describe energy use by sector, segment, and end use

for 2009.

4. Developed a baseline electricity forecast by sector, segment, and end use for 2012 through

2032. Results presented in this volume are through 2030.

5. Identified and analyzed energy-efficienc y measures appropriate for the Valley.

6. Estimated four levels of energy-efficiency potential, Technical, Economic, Achievable - High,

and Achievable - Low

.

7. Reviewed the current programs offered by TV A in light of the study findings to make

strategic program recommendations for achieving savings.

The results from these steps are presented in the remainder of this chapter. Details are provided

in Volume 2.TVA Energy Efficiency Potential Study, Volume 1 Energy Efficiency Potential

### Figure 2-1 Overview of Analysis Approach



# Market Characterization

The Tennessee Valley Authority (TVA) is the largest electric utility in the U.S. on the basis of

energy sales, with annual sales of 174 billion kWh in 2010. 2 

## TVA serves as the wholesale provider

for 155 power distributors and directly serves 59 industrial and federal facilities. Its service

territory, with an approximate area of 80,000 square miles, encompasses more than 9 million

people in seven southeastern states. It includes nearly the entire state of Tennessee as well as

portions of Alabama, Georgia, Kentucky, Mississipp i, North Carolina, and Virginia. Major cities are

Memphis, Nashville, Knoxville, Huntsville, and Chattanooga. The top industries in the service

territory are chemical products, primary metals, paper products, and food products.

Total electricity use for the residential, commerc ial and industrial sectors for TVA in 2009 was

146,118 GWh. 3 

## As shown in Figure 2-2, the largest sect or is residential, accounting for 42%, or

62,246 GWh. The remaining use is split between th e commercial and industri al sectors, at 39,561

GWh and 44,311 GWh respectively.

Figure 2-3 presents the end-use sh ares of residential electricity use for each housing type. Here,

the single family segment is shown as a segment average as well as broken out into single family

all-electric homes and single family other homes. The TVA territory has a large number of allelectric homes, roughly half of the single family homes in the Valley, with comparatively larger

consumption in heating, water heating, and cooking.

Figure 2-3 End-Use Shares of Total Electricity Use by Housing Type, 2009

# Baseline Forecast

Prior to developing estimates of energy-efficie ncy potential, a baseline end-use forecast was

developed to quantify how electricity is used by end use in the base year and what the

consumption is likely to be in the future in absence of new utility programs and naturally

occurring efficiency. The baseline forecast serves as the metric against which energy efficiency

potentials; technical, economic, and achievable, are measured. The baseline forecast we

developed for TVA was consistent with its official forecast from October 2011.

Figure 2-6 through Figure 2-8 present the base line end-use forecasts for the residential,

commercial and industrial sectors. Referring to Ta ble 2-1 and Figure 2-9, electricity use across all

three sectors is expected to increase by 24% between the base year, 2009, and 2030, for an

average annual growth rate of 1.0%.

• The residential sector has the highest growth , with a 33% increase (1.4% annual growth

rate) over the forecast horizon.

• The commercial sector has a dip in the short term and then recovers after 2015. Overall, it

has the slowest growth at 0.6% per year on average.

• The industrial sector shows a steady increase in use throughout the forecast period with an

average growth rate of 0.9% per year.

# Energy Efficiency Measures

The first step of the energy efficiency measure analysis was to identify the list of all relevant

energy efficiency measures that should be cons idered for the TVA potential assessment. Sources

for the measure assumptions were drawn from TVA’s Measurement Manual and latest program

evaluation results, Global’s building modeling tool BEST, and Global’s other measure databases

from previous studies and program work.

The measures are categorized into two types according to the LoadMAP 4 

## taxonomy: equipment

measures and non-equipment measures:

• Equipment measures, or efficient energy-consuming piec es of equipment, save energy by

providing the same service with a lower energy requirement. An example is the replacement

of a standard efficiency refrig erator with an ENERGY STAR model. For equipment measures,

many efficiency levels are available for a specific technology that range from the baseline

unit (often determined by code or standard) up to the most efficient product commercially

available. For instance, in the case of central ai r conditioners, this list begins with the federal

standard SEER 13 unit and spans a broad spectrum of efficiency, with the highest efficiency

level represented by a SEER 21 unit.

• Non-equipment measures save energy by reducing the need for delivered energy but do

not involve replacement or purchase of major end-use equipment (such as a refrigerator or

air conditioner). An example would be a progra mmable thermostat that is pre-set to run the

air conditioner only when people are home. Non-equipment measures fall into one of the

following categories:

• 

## Building shell (windows, insulation, roofing material)

• 

## Equipment controls (thermostat, occupancy sensors)

• 

## Equipment maintenance (cleaning filters, changing setpoints)

• 

## Whole-building design (natural ventilation, passive solar lighting)

• 

## Lighting retrofits (included as a non-equipment measure because retrofits are

performed prior to the equipment’s normal end of life)

# Energy Efficiency Potential Results

Table 2-3 and Figure 2-10 summarize the energy-efficiency savings for the different levels of

potential relative to the baseline forecast. Figure 2-11 displays the energy-efficiency forecasts.

• Achievable - Low potential forms a lower point on the range of achievable potential.

Across all sectors, this metric is 3,256 GWh in 2015 and increases to 19,093 by 2030. This

represents 2.2% of the baseline forecast in 2015 and 10.6% in 2030. By 2030, Achievable –

Low offsets 55% of the growth in the baseline forecast.

• Achievable - High potential forms the upper bound on the range of achievable potential.

It is 7,494 GWh in 2015, which represents 5.0% of the baseline forecast. By 2030, the

cumulative savings are 35,781 GWh, 19.8% of the baseline forecast, for an annual average

of just over 1% per year. By 2030, Achievable – High completely offsets growth in the

baseline forecast.

• Economic potential

, which reflects the savings when all cost-effective measures are taken,

is 12,418 GWh in 2015. This re presents 8.4% of the baseline energy forecast. By 2030,

economic potential reaches 44,821 GWh, 24.8% of the baseline energy forecast.

• Technical potential

, which reflects the adoption of all energy efficiency measures

regardless of cost-effectiveness, is a theoretical upper bound on savings. In 2015, energy

savings are 15,347 GWh, or 10.3% of the baseline energy forecast. By 2030, technical

potential reaches 57,244 GWh, 31.6% of the baseline energy forecast.

Figure 2-12 focuses on the range of residential achievable potential in 2015 and 2030.

• Lighting equipment replacement accounts for th e highest portion of the savings in the near

term as a result of the efficiency gap between advanced incandescent lamps and CFL lamps.

• Water heating accounts for large savings in th e long term because heat pump water heaters

are found to be cost-effective.

• Electronics, appliances, and space conditioning measures also contribute significantly to the

savings.

Figure 2-12 Residential Achievable Potential by End Use in 2015 and 2030

Figure 2-13 compares the range of potential in 2015 and 2030 for the commercial sector. Not

surprisingly, interior lighting delivers the highest achievable savings throughout the study period.

In 2015, exterior lighting is second, office equipment is third, and ventilation and cooling are

next highest in terms of Achievable - Low potential. In 2030, though interior lighting still

provides the greatest Achievable - Low potentia l, cooling is the second greatest source of

savings, followed by refrigeration and exterior lighting.TVA Energy Efficiency Potential Study, Volume 1 Energy Efficiency Potential

specific measures that account for the larg est savings in the indu strial segment are:

• Integrated plant energy management: 45 MWh and 392 MWh of Achievable – Low

potential in 2015 and 2030 respectively

• Fan and pump system measures, which include system optimization, energy

management, and equipment upgrades: 135 GWh and 1,425 GWh of Achievable – Low

# EE Program Recommendations

The results of the EE assessment reveal that TVA has significant potential for energy efficiency

resources over the next two decades. Our analysis has shown that TVA can realize an achievable

range of reductions between 10.4% and 19.4% of the baseline forecast in 2030 with the

measures represented in this report.

TVA’s energy-efficiency programs are off to a strong start, with a comprehensive suite of

programs currently moving from the planning phas e to the implementation phase. Based on this

study, Global provides the following recommendat ions to preserve and augment that momentum.



## General Recommendations

• Coordinate distributor layer between TVA and end-user: As a wholesale provider for

155 power distributors, TVA’s business landscape poses unique challenges for the

administration of energy efficiency programs. Because of this arm’s-length relationship with

end users, TVA does not have the same leve l of information about customers as other

utilities. TVA will need to coordinate closely with its power distributors. To facilitate better

coordination, TVA should consider the hiring an d training of dedicated personnel to serve as

liaisons with the distributors.

• Maintain transparent stakeholder process: To date, TVA has been transparent and

aboveboard with internal and ex ternal stakeholders. Continuing to involve stakeholders and

cultivating a mutual understanding of continuo us improvement is of paramount importance

to the future success of programs. We reco mmend an open and tr ansparent stakeholder

process with regular touchpoints and workshops. Suggested workshop topics are: technical

resource manual with deemed measure database s; evaluation, measurem ent, and verification

protocols; emerging technolo gies; innovative program strategies; periodic reviews of

program results; and sharing success stories from individual power distributors or customers.

• Create internal EE targets: TVA should continue to evolve and formulate its specific

objectives regarding energy e fficiency by creating targets and goals. Global recommends

targets that fall within the range of achievab le potentials identified in this study.

• Aggressively pursue lighting savings in the near-term: Lighting represents a bulk of

the low-hanging fruit in the near term, with significant untapped potential in all sectors.

Programs have not yet aggressively targeted lighting, beyond a limited CFL giveaway effort.

Working upstream with trade allies and retailers will likely yield significant savings. In

particular, as the EISA standards take effect, educational programs and coordination with

retailers can help customers move beyond EISA -compliant lamps to more efficient CFL and

LED technologies.

• Create targeted marketing messages: Energy prices in the Va lley are cheaper than the

national average. Correspondingly, the custom er base does not have a long history of

exposure to marketing and education regarding energy and sustainability issues like other

jurisdictions around the nation . As a result, customers have not been strongly driven to

consider energy efficien cy measures, and awareness and adopti on will be lower than national

averages at first. Targeted marketing and education efforts should be developed with

messages that speak to the customer ba se and cultivate shared attitudes.

• Expand knowledge of the customer base: TVA’s pre-existing data regarding the

customer base is minimal. Opportunities should be explored to expand this knowledge base.

Not only will this information be valuable for program efforts, the results can be shared with

distributors, many of whom are too small to conduct surveys on their own. Surveys should

collect data in all sectors on end use equi pment saturations, customer attitudes, and

measure penetration.TVA Energy Efficiency Potential Study, Volume 1 Energy Efficiency Potential

## Residential Recommendations

• Pursue CFLs: Significant, cost-effective potential is available with CFLs, in spite of the

forthcoming EISA standards that will reduce their per-unit savings compared to the new

baseline. Also, TVA should focus strong attent ion on specialty CFL programs, as these bulbs

are not addressed in the EISA standard.

• Focus on all-electric homes: The prominence of all-electric homes, roughly 50%, has

many implications for program design. Audit pr ograms with direct in stall measures are one

mechanism for reaching these customers. New co nstruction incentives can help to boost the

penetration of heat pumps, heat pump water heaters (HPWH), and advanced construction

designs.

• Pursue heat pump water heaters: Heat pump water heaters offer significant potential,

but educational efforts, for trade allies as we ll as homeowners, will be required to achieve

this potential. Consider bundling HPWH with the existing and establis hed space conditioning

heat pump program to take advantage of the gains the heat pump programs have made in

acquainting trade allies and targeted part icipants with heat pump technology.



## Commercial and Industrial Recommendations

• Pursue lighting savings: Strongly pursue lighting savings to accelerate the phase out of

T12 fluorescent lighting. In particular, program efforts can help intercept building operators

before they make purchase and stocking decisions that could lead to the hoarding of T12

lamps.

• Create customized, multi-year plans for large, complex customers : For large enough

customers, large success can be obtained with strategic energy management (SEM) 5



## initiatives over longer time horizons. This me ans a larger tracking an d time commitment, but

many jurisdictions are finding this to be a more effective method than a “one and done”

installation and rebate approach. These relationships involve personalized plans,

identification of metrics, goal-setting, technical assistance, and attention from account

executives.

• Focus program efforts on motor controls and system optimizations: Low-cost

retrofits can have significant, low-cost energy impacts with minimal disruption (and often

times improvement) of business processes.

## CHAPTER 3



# DEMAND RESPONSE POTENTIAL

Analysis Approach

The analysis approach for estimating demand resp onse potential is, by necessity, different from

the approach used for energy efficiency. Energy efficiency can occur outside of utility programs

to the extent that it is naturally occurring or technology driven; but can be enhanced and

enabled by utility programs. Demand response, however, does not exist without a utility

program. A program-by-program an alysis is therefore at the core of a demand-response potential

study. The basic steps used to perf orm this assessment are as follows:

1. Characterize the market. The first step is to segment the market into the relevant

customer segments. The first level of segmen tation is by sector: residential and C&I

customers. Within residential customers, we further segment the population by describing

housing types and presence of end uses (suc h as single family homes with central air

conditioning (CAC) and electric water heating). For C&I customers, the next level of

segmentation is based on the maximum dema nd values, typically following utility rate

schedules.

2. Identify baseline forecast. The second step is to identify what the peak demand forecast

will be, absent any DR programs, for both summer and winter in the TVA service territory.

3. Define relevant DR options. The next step is to identify applicable DR options for each

customer segment. DR options include direct load control (DLC), curtailable, demand

reduction, capacity reduction, load shifting, pr icing, and voltage reduction programs. Each of

these options is mapped to th e applicable customer segments . For some options, such as

DLC, specific end uses can be controlled and th ey are identified. Also, enabling technologies,

such as programmable communicating thermostats (PCT) are identified by customer

segment.

4. Outline DR program participation hierarchy. For each customer segment that has more

than one DR option, the next step is to define the participation hierarchy. This accounts for

program overlaps and ensures that cross-part icipation in DR events and double counting

does not take place.

5. Develop program parameters. Program parameters include pa rticipation rates, number of

participants equipped with enabling technology, un it load reduction impacts, attrition rates,

and DR event participation rates. Cost data are also developed for the analysis, including

program development costs, customer marketing and recruitment costs, technology costs,

customer incentives, operation and maintenanc e (O&M) costs, and program administrative

costs.

6. Estimate preliminary potential and assess cost-effectiveness. The final step is to

estimate the load reduction potential associated with each of the DR options by customer

segment, and also at the aggregate level ac ross programs and segment. Utility-provided

avoided capacity costs are used to assess benefits from DR programs

7. Develop estimates of achievable potential. The final step is to estimate the load

reduction potential associated with each of the DR options by customer segment, and also at

the aggregate level across programs and segment. Achievable potential takes into account

expected participation rates as well as cost-effe ctiveness of the program. For this study, we

estimate a range of achievable potential:TVA Energy Efficiency Potential Study, Volume 1 Demand Response Potential

3-2 www.gepllc.com 

## • Achievable – High assumes higher participat ion rates that result from application of

industry best practices in program design, higher budget limits for implementation, and

does not incorporate the results of the cost effectiveness screen. Therefore, Achievable

– High represents the upper bound of savings, regardless of cost.

• Achievable – Low assumes lower levels of part icipation as a result of limited budgets for

program implementation and includes only those programs that pass the costeffectiveness screen. Therefore the Achievable – Low represents a more realistic picture

of DR potential given barriers to pa rticipation and cost constraints.

Unlike the energy-efficiency analysis, we do not consider technical or economic potential for

demand response.TVA Energy Efficiency Potential Study, Volume 1 Demand Response Potential

# Matrix of Demand Response Options

For this study, a broad set of demand response options that combines traditional and emerging

approaches was identified. They fall into eight groups: direct load control programs, curtailable

programs, demand and capacity reduction prog rams, dynamic pricing programs, aggregator

managed programs, load shifting programs, voltag e regulation programs, and fast-DR. Table 3-1

translates the eight groups into eleven specif ic options by customer segment and identifies the

enabling technology options an d targeted end uses for each.

# Demand Response Potential Results

Demand response has the potential to reduce peak demand by 1,504 MW to 1,520 MW in 2012.

The achievable potential increases to a range of 3,870 MW to 4,579 MW in 2030. 8



## Table 3-3 presents the overall summary of demand response potential for the two cases. Figure

3-1 presents this information graphically. The primary observations are:

• In summer of 2012, achievable potential reduces peak demand by approximately 5%. This

starting point takes into account the achiev ements in 2011 from TVA’s current DR program

portfolio.

• By summer of 2030, the achievable potential reduce s peak demand by 10% to 12%. This level of

savings represents an offset in growth of between 53% and 63%.

• In winter of 2012, achievable potential reduces peak demand by approximately 4%.

• By winter of 2030, the achievable potential reduces peak demand by 8% in the low case and 9%

in the high case which represents an offset in growth of between 71% and 80%.

considered distinct from traditional DR events. Customers can dual enroll in Fast DR and any other customer based dispatchable DR

program, therefore the impacts associated with DR cannot be added to the total potential.TVA Energy Efficiency Potential Study, Volume 1 Demand Response Potential

3-6 www.gepllc.com 

# Potential Estimates by DR Program Type

Table 3-4and Table 3-5 show the range of achievable potential for each program type in both

summer and winter. The primary obse rvations from the analysis are:

• Capacity reduction has, by far, the largest contribution to the overall potential from all DR

programs, with a 33% share in the total achievab le potential in the high case in 2030. The

achievable potential for this program represents a migration from the curtailable program to the

capacity reduction program by 2016. 9



## • The Curtailable program is phased out completely by the year 2016 as all participants migrate

into the Capacity Reduction option. In our experi ence, this trend is common in the industry as

many utilities move away from emergency response programs and toward programs that can be

integrated into wholesale markets ba sed on economic dispatch models.

• While the total potential attributable to DLC va ries widely from 645 MW and 17% in the low case

to 1,174 MW and 26% in the high case DLC rema ins the second largest contributor to overall

potential. The key difference between estimates of potential in the high and low case is the

participation rates. The high case assumes an e ffective participation of 23.1% while the low case

assumes an effective participation of 11.3%. DLC potential also varies from summer to winter;

this is a result of the saturation of central ai r conditioning in the Tennessee Valley being higher

than the saturation of electric heat.

• The Voltage Reduction programs also contribute substantially to the overall potential with CVR

contributing 14% and DVR contributing 4% to overall potential.

• Savings from the Third Party Aggregated program co me in fourth with an 11% share of the total

potential in 2030. When combined with the Distribu tor Aggregated Program, which is very similar

to the Third Party Program, the two programs represent 16% of the total potential in 2030.

• Savings from the Dynamic Pricing program are modera te with a total contribution of about 4% in

2030. Under a voluntary scenario, we assume a very conservative participation rate, which limits

the potential of this program type.

• Load shifting has the smallest contribution to overall potential with about a 2% contribution in

2030.

9 This migration is representative of the migration of custom ers from TVA’s current 5MR and 60MR programs to the new Reserve

Preservation program which falls within the capacity reduction program option for this study.TVA Energy Efficiency Potential Study, Volume 1 Demand Response Potential

## Figure 3-2 and Figure 3-3 show the range of achievable potential by customer class. The

residential class has the largest contribution to overall potential at 41% in 2030 for the high

achievable case. This is primarily due to participation in the DLC program option. Large C&I and

Direct Serve come in second and third in overall contribution to potential, with 14% and 21%

respectively, with their contribution being co ncentrated heavily in the capacity reduction

program. Large, Medium C&I contribute 12% and 9% to overall potential respectively. Small C&I

has the smallest contribution with 4%.

# Summary of Cost-Effectiveness Analysis Results

Table 3-6 presents a summary of the cost-effect iveness results based on the TRC test for all

programs. 10 

## The cost effectiveness tests were perf ormed using a bottom up approach that

employs cost assumptions based on secondar y information and industry best practices. 11 

## The

analysis was performed in this manner in order to provide TVA with realistic annual costs that

can be passed on to distributors including: equi pment costs, incentive co sts, administrative, and

marketing costs 12 

## . The results of the TRC test analysis show that the overall portfolio of DR

programs is cost-effective. 13 

## The cost-effectiveness assessment is done for the Achievable - High

level.

The most cost effective programs are Curtaila ble, Capacity Reduction, Demand Reduction,

Dynamic Pricing and Fast DR. Curtailable has th e highest B/C ratio due to a shortened program

life of three years. Demand Reduction, Capacity Reduction, and Dynamic Pricing are also highly

cost effective. These programs have lower admini strative costs, and fewe r equipment costs than

the other non-aggregated programs . The voltage regulation progra ms are also considered cost

effective, however it is important to note that costs for these programs are based solely on the

incentive payment that TVA pays to the distribu tors. All equipment and im plementation costs are

assumed to be covered by that incentive and addi tional external (rate-based) costs and benefits

to the distributor are not captured. The remain ing programs; DLC, Third Party and Distributor

Aggregated, and Load Shifting, are all cost effective with B/C ratios ranging from 1.05 to 1.31.

# DR Program Recommendations

The results of the DR assessment reveal that TV A has significant potential for demand response

resources over the next two decades. Our analysis has shown that it is economically feasible for

TVA to realize up to 11% reductions in summer pe ak and 9% reductions in winter peak by 2030

if it moves forward with the DR options represented in this report.

TVA’s demand response programming efforts have a strong basis with larg e C&I customers in the

field today. Moreover, a comprehensive suite of new programs is currently emerging from the

planning phase and entering the im plementation phase. In light of this study, Global provides the

following recommendations to preserve and augment that momentum.

10 Cost effectiveness results by program and customer segment are included in Appendix B.

11 Cost effectiveness inputs and assumptions are included in Appendix A.

12 While utility incentives are not included in the TRC test as co sts, we provide estimates of incentives that could reasonably b e

assumed for each program in the appendix.

13 The $/kW payment for the Dist ributor aggregated program was ad justed from the $63/kW year in the TVA provided program data

sheet to $55/kW year in order for the program to pass the econ omic screen. The Distributor Aggregated program was not cost

effective given our assumptions in the analysis at the higher in centive rate. Payments from the utility to aggregators for both the 3 rd

Party Aggregated and Distributor Aggregated programs are included as implementation costs in the TRC analysis.TVA Energy Efficiency Potential Study, Volume 1 Demand Response Potential

3-10 www.gepllc.com 

## • Expand programs to include smaller customers: TVA’s current DR programs total

approximately 1,300 MW of DR, which indicates that the potential for future success with

new DR programs is very high. The majority of the currently installed DR capacity is

concentrated in the Large, X-Large, and Di rect Serve customers. Targeting the largest

customers first is an excellent strategy for utilities as they begin their DR efforts, however, as

portfolios mature it becomes necessary to target other customer segments such as

residential and small and medium C&I.

• Focus efforts on programs with the largest potential: DLC and Capacity Reduction are

the DR programs with the largest opportuni ty for savings among end-users. DLC is a

program that can be targeted to residential and small commercial customers and has been

shown to be very successful given the right combination of technology and incentives. 14



## Capacity reduction is gaining ground on the we st coast as a highly favorable program with

commercial and industrial customers. Customer s particularly like the monthly capacity

payments they receive all year long and the flexibility to determine their own reduction bid.

Marketing efforts to expand DR program partic ipation to the smaller customers should focus

on DLC and capacity reduction.

• Voltage regulation programs need carefully designed incentives: Voltage reduction

has significant potential to reduce demand on the distribution side. This is a unique program

in that it involves infrastructure improvements to optimize and reduce voltage levels without

affecting the power quality ultimately distributed to end users. Sufficient incentives will be

needed to encourage distributors to partic ipate in this program and therefore more

information on the cost of specific voltage regulation technologies will need to be gathered.

• Coordinate distributor layer between TVA and end user: Because TVA is a wholesale

provider, maintaining a cohesive DR message to end users may be challenging, especially as

DR programs focus on residential and sma ll C&I customers. We recommend dedicated

resources to ensure that TVA programs are marketed and implemented consistently across

distributors.

• Create internal DR targets: TVA should continue to evolve and formulate its specific

objectives regarding demand response by creating targets and goals. Global recommends

targets that fall within the range of achievab le potentials identified in this study.

• Consider limiting the number of programs: TVA has a longer list of DR programs than

many utilities do. TVA may consider limiting the number and type of DR programs to

facilitate distributor and end-user understanding. Customers are often overwhelmed by too

many options when it comes to utility programs, and many utilities with a large number of

programs are now focused on reducing or bund ling programs to make participation simpler

for customers. We recommend focusing on th ose programs with th e highest potential:

capacity reduction in the C&I sectors, DLC in the residential sector, and voltage reduction for

the distributors.

• Provide market-friendly customer incentives : Most customers are willing to offer their

loads for participation in demand response prog rams if the utility is willing to compensate

them for any inconvenience that they may rea lize due to the temporary service interruption.

While incentive strategies must be structured in a way that ensures economic viability for the

program, we have found that there is signific ant room to expand customer incentives while

still maintaining cost-effectiveness.

• Provide enabling technology incentives: Enabling technology has been shown to

improve the reliability of DR resources and to maximize load reduction in DR programs. It is

therefore crucial to provide incentives to customers for adopting enabling technology in order

to automate response to DR events.

rates of 20% or more.Global Energy Partners 4-1

# COMPARISON OF PREVIOUS POTENTIAL STUDIES

Analysis Approach

Previous studies of energy efficiency potential for the Valley and for the southeast region have

produced a range of results. The obje ctives of this task are as follows:

• Develop a detailed report comparing the results of Task 1 to regional potential studies that

are specific to the southeast.

• Consider the methodology, assumptions, approaches, estimated baselines, technical

performance, adoption, and program/re gulatory context of the studies.

• Create a matrix to enable side by side comparison of the studies.

The most directly comparable studies to the Gl obal TVA study are the EPRI National Study and

EPRI’s 2010 study of the TVA service territory. These both use a similar bottom-up modeling

approach.

The most dissimilar studies are th e REPP “Powering the South” study, because of its age, and the

McKinsey study because of its different definitions and methodologies, as discussed in Volume 2.

As far as baseline forecasts, the assumptions used in the various studies are all relatively similar.

Except for the REPP study mentioned above, all the baseline forecasts are relatively recent and

15 10-year and 20-year savings are approximations. Because several studies start one or two years earlier or later, they do not f it in

these categories exactly, but this simplification is made for comparison purposes.TVA Energy Efficiency Potential Study, Volume 1 Comparison of Previous Potential Studies

## include the effects of the EISA lighting standards. However, Global’s baseline forecast includes

the appliance and equipment standards that were adopted in 2010, which was a major year for

new standards. This has the most significa nt impact in the residential sector.

Overall, Global’s savings estimate s are higher than either of the EPRI studies. They are in line

with the other studies to the extent they are co mparable. Direct comparison from study to study

should be made mindfully, taking into account the caveats and considerations spelled out in the

EE and DR Volumes.

potentials are analyzed. With the exception of some differences in definition of potentials in the

FERC National study, these three studies are relatively comparable.Global Energy Partners

# INTRODUCTION

Background

The Tennessee Valley Authority (TVA) has contracted with Global Energy Partners (Global) to

conduct a potential study to assess 20-year pote ntials for energy efficiency (EE) and demand

response (DR). TVA has an aspirational goal to lead the southeast in energy efficiency, and

believes this leadership can be accomplished through the development and implementation of

action plans for EE, DR, and end-use generation. Th is potential study will provide information to

assist TVA in meeting that goal.

Toward this end, Global conducted a detaile d, bottom-up assessment of the TVA market to

deliver forecasts of energy use and peak demand, as well as forecasts of energy and peakdemand savings achievable through energy ef ficiency and demand response programs. The 20-

year potentials study addresses the residential, small commercial, large commercial, and

industrial sectors. Results of this task are di scussed in two volumes, one for energy efficiency

and one for demand response, as described below in the report organization.

Global also compared the results of the potential savings to those from existing regional potential

studies that are specific to the Southeast and other select studies. This analysis, which appears

in both the energy efficiency and demand resp onse reports, also compares these potential

studies with regard to methodology, assumpti ons, approaches, estimated baselines, technical

performance, adoption, and pr ogram/regulatory context.



# Objectives

Key objectives for the study include:

• Conduct a 20-year bottom-up energy efficiency po tential study to determine the potential for

specific energy efficiency measures to reduce the consumption and peak demand of

electricity in the TVA service territory.

• Conduct a demand response potential study to determine the potential for reduction in peak

demand through demand response programs.

• Compare the potential study results with other national and regional studies, including details

regarding assumptions used to develop each of the studies.

# Definitions of Potential

In this study, we estimate the potential for energy efficiency savings. The savings estimates

represent gross savings 1 

## developed into three types of potential: technical potential, economic

potential, and achievable potential. Technical an d economic potential are both theoretical limits

to efficiency savings. Achievable potential em bodies a set of assumpti ons about the decisions

consumers make regarding the efficiency of th e equipment they purchase, the maintenance

activities they undertake, the controls they use for energy-consuming equipment, and the

elements of building construction. For this reason , we developed a range of achievable potential.

These levels are described below.

Technical potential is defined as the theoretical upper limit of energy efficiency potential. It

assumes that customers adopt all feasible measur es regardless of their cost. At the time of

equipment failure, customers replac e their equipment with the most efficient option available. In

new construction, customers and developers also choose the most efficient equipment option.

Examples of measures that make up technical potential in the residential sector include:

• Ductless mini-split air conditioners with variable refrigerant flow

• Ground source (or geothermal) heat pumps

• LED lighting

Technical potential also assumes the adoption of every available other measure, where

applicable. For example, it includes installation of high-efficiency windows in all new construction

opportunities and air conditioner maintenance in al l existing buildings with central and room air

conditioning. The retrofit measures are phased in over a number of years, which is longer for

higher-cost measures.

Economic potential represents the adoption of all cost-effective energy efficiency measures.

In this analysis, the total resource cost (TRC) te st, which compares lifetime energy and capacity

benefits to the incremental cost of the measure, is applied. Economic potential assumes that

customers purchase the most cost-effective opti on at the time of equi pment failure and also

adopt every other cost-effecti ve and applicab le measure.

Achievable - High potential takes into account expected program participation resulting from

ideal implementation conditions and customer preferences for energy-efficient technologies and

demand response programs. Achievable - High es tablishes a maximum target for the EE savings

that a utility can hope to achieve through its EE programs and involves incentives that represent

a substantial portion of the incremental cost co mbined with high administrative and marketing

costs.

Achievable - Low potential represents a lower bound on Achievable potential. It reflects

limited DSM budgets and significant barriers to customer acceptance.

1 Savings in “gross” terms instead of “net” terms means that the baseline forecast does not include naturally occurring efficien cy. In

other words, the baseline assumes that energy efficiency levels re main fixed as they are today. This rule holds true except in cases

where enactment of future codes and standa rds were on the books before January 2011, e.g. the effects of the EISA 2007 lighting

efficiency standard.TVA Energy Efficiency Potential Study, Volume 2 Introduction

# ANALYSIS APPROACH AND DATA DEVELOPMENT

Analysis Approach

To perform the energy efficiency analysis, Global used a bottom-up analysis approach as shown

in Figure 2-1. We took the following steps.

1. Held a meeting with the project team to refine th e objectives that were identified in the TVA

RFP. This resulted in a work plan for the study.

2. Performed a market characterization to desc ribe sector-level electricity use for the

### Figure 2-1 Overview of Analysis Approach



## LoadMAP Model

We used Global’s Load Management Analysis and Planning tool (LoadMAP TM 

## ) version 3.0 to

develop both the baseline forecast and the estima tes of energy efficiency potential. Global

developed LoadMAP version 1.0 in 2007 and has enhanced it over time, using it for the EPRI

National Potential Study and numerous utility-spec ific forecasting and potential studies. Built in

Excel, the LoadMAP framework (s ee Figure 2-2) is both accessible and transparent and has the

following key features.

• Embodies the basic principles of rigorous end-use models (such as EPRI’s REEPS and

COMMEND) but in a more simplified, accessible form.

• Includes stock-accounting algorithms that tr eat older, less effici ent appliance/equipment

stock separately from newer, more efficient eq uipment. Equipment is replaced according to

the measure life defined by the user.

• Balances the competing needs of simplicity and robustness by in corporating important

modeling details related to equipment saturation s, efficiencies, vintag e, and the like, where

market data are available, and treats end uses separately to account for varying importance

and availability of data resources.

• Isolates new construction from existing eq uipment and buildings and treats purchase

decisions for new construction and existing buildings separately.

• Uses a simple logic for appliance and equipmen t decisions. Other models available for this

purpose embody complex decision choice algori thms or diffusion assumptions, and the model

parameters tend to be difficult to estimate or observe and someti mes produce anomalous

results that require calibration or even overri ding. The LoadMAP approac h allows the user toTVA Energy Efficiency Potential Study, Volume 2 Analysis Approach and Data Development

## drive the appliance and equipment choices year by year directly in the model. This flexible

approach allows users to import the results from diffusion models or to input individual

assumptions. The framework also fa cilitates sensitivity analysis.

• Includes appliance and equipment models custom ized by end use. For example, the logic for

lighting equipment is distinct from refrigerators and freezers.

• Can accommodate various levels of segmentation. Analysis can be performed at the sector

level (e.g., total residential) or for customized segments within sectors (e.g., housing type or

income level).

Consistent with the segmentation scheme and the market profiles we describe below, the

LoadMAP model provides forecasts of baseline en ergy use by sector, segment, end use, and

technology for existing and new buildings. It al so provides forecasts of total energy use and

energy-efficiency savings associated with the four types of potential. 2



### Figure 2-2 LoadMAP Analysis Framework



## Market Characterization

Before assessing the potential savings from EE, it is critical to develop a good understanding of

where TVA is today in terms of electricity use and customer behavior. Th e purpose of the market

assessment is to develop market profiles that desc ribe current electricity use in terms of sector,

customer segment, and end use. The base year for this study is 2009 since that was the most

recent year for which a complete set of utility data were available.

Segmentation for Modeling Purposes

The market assessment began by defining the ma rket segments (building types, end uses, and

other dimensions) that are relevant in the Valle y. The segmentation sche me employed for this

project is presented in Table 2-1.

2 The model computes energy and peak-demand forecasts for each type of potential for each end use as an intermediate calculation

. Annual-energy and peak-demand savings are calculated as the difference between the value in the baseline forecast and the value in

the potential forecast (e.g., the technical potential forecast).

## The commercial sector, which includes both dist ributor-served and directly served accounts, was

characterized as small commercia l and large commercial to correspond to TVA and distributor

rate schedules. For the commercial sector, it is useful to analyze the segments based on the

unique characteristics of the building type. For this study, we used the following 15 building

types:

• Small Commercial (less than or equal to 50 kW)

o Small Office —all types of offices, including medical/dental offices

o Restaurant — fast-food, sit-down and cafeteria-style restaurants

o Small Retail — retail establishments such as small boutiques and mini-malls

o Small Grocery — convenience stores and small markets

o Warehouse — storage facilities, unrefrigerated

o Small Miscellaneous — all remaining small building types, such as police stations,

parking garages, etc.

• Large Commercial (gre ater than 50 kW)

o Large Office — all types of offices including large government facilities

o Large Retail — retail establishments such as large box retailers and malls

o Large Grocery — supermarkets

o Refrigerated Warehouse — climate-controlled cold storage

o School — primary and secondary schools

## The industrial sector, which for this study includ es both power distributor served and directly

served accounts, is segmented by industry type. Because the industrial sector is complex and

diverse, the study isolated for analysis the four largest industries, which accounted for 59% of

total 2009 industrial electricity sales, and combined the remaining industries into a single

category. The resulting segmentation is as follows:

• Chemical Products

• Primary Metals

• Paper Products

• Food Products

• Other Industrial

In addition to segmentation by industry, we identified the set of end uses and technologies that

are appropriate for TVA. These are shown in Table 2-4.

## With the segmentation scheme defined, we then performed a high-level ma rket characterization

of electricity sales in the base year to allocate sales to each customer segment. We used various

data sources to identify the annual sales in each customer segment, as well as the number of

customers for residential segments, and the square footage or employee count for theTVA Energy Efficiency Potential Study, Volume 2 Analysis Approach and Data Development

Global Energy Partners 2-9

An EnerNOC Company 

## commercial and industrial segments. This inform ation provided control totals (energy use and

customers counts/square footage/employee totals ) for calibrating the LoadMAP model to known

data for the base-year.



## Market Profiles

The next step was to develop market profiles fo r each sector, customer segment, end use, and

technology. A market profile includes the following elements:

• Market size is a representation of the number of customers in the segment. For the

residential sector, it is number of households. In the commercial sector, it is floor space

measured in square feet. For the industrial sector, it is number of employees.

• Saturations define the fraction of buildings with th e electric technologies. (e.g., homes with

electric space heating, commercial floor space with space cooling).

• UEC (unit energy consumption) or EUI (energy-use index) describes the amount of

electricity consumed in 2009 by a specific technology in buildings that have the technology.

We use UECs expressed in kWh/household for th e residential sector, and EUIs expressed in

kWh/square foot or kWh/employee for the commercial and industrial sectors respectively.

• Intensity for the residential sector represents the average use for the technology across all

homes in 2009. It is computed as the product of the saturation and the UEC and is defined

as kWh/household. For the commercial and indust rial sectors, intensity, computed as the

product of the saturation and the EUI, repres ents the average use for the technology across

all floor space in 2009.

• Usage is the annual electricity use by a technology/e nd use in the segment. It is the product

of the market size and intensity and is quantified in GWh.

The market assessment results and the market profiles are presented in Chapter 3.



## Baseline Forecast

The next step was to develop the baseline forecast of annual electricity use and peak demand for

2009 through 2032 by customer segment and end use without new utility programs or naturally

occurring efficiency scenario. The end-use forecast does include the relatively certain impacts of

codes and standards that will un fold over the study timeframe. All such mandates that were

defined as of January 2011 are included in the ba seline. The baseline forecast is the foundation

for the analysis of savings from future EE efforts as well as the metric against which potential

savings are measured.

Inputs to the baseline forecast include:

• Current economic growth forecasts (i .e., customer growth , income growth)

• Electricity price forecasts

• Trends in fuel shares and equipment saturations

• Existing and approved changes to building codes and equipment standards

• TVA’s internally developed forecasts for electricity sales

We present the results of the baseline forecast development in Chapter 4.



## Energy Efficiency Measure Analysis

This section describes the framework used to asse ss the savings, costs, and other attributes of

energy-efficiency measures. These characterist ics form the basis for measure-level costeffectiveness analyses as well as for determining measure-level savings. For all measures, Global

assembled information to reflect equipment pe rformance, incremental costs, and equipment

lifetimes. We used this information, along with TVA’s avoided costs data, in the economic screenTVA Energy Efficiency Potential Study, Volume 2 Analysis Approach and Data Development

2-10 www.gepllc.com 

## to determine economically feasible measures. Figure 2-3 outlines the framework for measure

analysis.

Figure 2-3 Approach for Measure Assessment

The framework for assessing savings, costs, and ot her attributes of energy efficiency measures

involves identifying the list of energy efficiency measures to include in the analysis, determining

their applicability to each market sector and segment, fully characterizing each measure, and

performing cost-effectiveness screening. Potent ial measures include the replacement of a unit

that has failed or is at the end of its useful life with an efficient unit, retrofit/early replacement of

equipment, improvements to the building envelo pe, the application of controls to optimize

energy use, and other actions result ing in improved energy efficiency.

We compiled a robust list of en ergy efficiency measures for each customer sector, drawing upon

a variety of TVA databases, TVA’s Measurement Manual, Global tools, and secondary sources.

This universal list of EE measures covers all major types of end-use equipment, as well as

devices and actions to reduce energy consumption. If considered today, some of these measures

would not pass the economic screens initially, but may pass in future years as a result of lower

projected equipment costs or higher avoided costs.

The selected measures are categorized into tw o types: equipment measures and non-equipment

measures, according to the LoadMAP taxonomy:

• Equipment measures, or efficient energy-consuming piec es of equipment, save energy by

providing the same service with a lower energy requirement. An example is the replacement

of a standard efficiency refrig erator with an ENERGY STAR model. For equipment measures,

many efficiency levels are available for a specific technology that range from the baseline

unit (often determined by code or standard) up to the most efficient product commercially

available. For instance, in the case of central ai r conditioners, this list begins with the federal

standard SEER 13 unit and spans a broad spectrum of efficiency, with the highest efficiency

level represented by a SEER 21 unit.

• Non-equipment measures save energy by reducing the need for delivered energy but do

not involve replacement or purchase of major end-use equipment (such as a refrigerator orTVA Energy Efficiency Potential Study, Volume 2 Analysis Approach and Data Development

Global Energy Partners 2-11

An EnerNOC Company 

## air conditioner). An example would be a progra mmable thermostat that is pre-set to run the

air conditioner only when people are home. Non-equipment measures fall into one of the

following categories:

• 

## Building shell (windows, insulation, roofing material)

• 

## Equipment controls (thermostat, occupancy sensors)

• 

## Equipment maintenance (cleaning filters, changing setpoints)

• 

## Whole-building design (natural ventilation, passive solar lighting)

• 

## Lighting retrofits (included as a non-equipment measure because retrofits are

performed prior to the equipment’s normal end of life)

• 

## Displacement measures (ceiling fan to reduce use of central air conditioners)

• 

## Commissioning and retrocommissioning

Non-equipment measures can apply to more than on e end use. For example, insulation levels will

affect the energy use of both cooling and space heating.

We developed a preliminary list of EE measures for TVA’s review. The final list included in the

study is presented in Chapter 5.

Once we assembled the list of EE measures, th e project team assessed their energy-saving

characteristics. For each measure we characterized incremental cost, service life, and other

performance factors. Following the measure ch aracterization, we pe rformed an economic

screening of each measure, whic h serves as the basis for developing the economic potential.

Representative Measure Data Inputs

To provide an example of the measure data, Ta ble 2-5 and Table 2-6 present samples of the

detailed data inputs behind both equipment an d non-equipment measures, respectively, for the

case of residential central air conditioning (CAC ) in single-family homes. Table 2-5 displays the

various efficiency levels available as equipmen t measures, as well as the corresponding useful

life, energy usage, and cost estimates. The columns labeled On Market and Off Market reflect

equipment availability due to codes and standard s or the entry of new products to the market.

Table 2-6 lists some of the non-equipment measures affecting CAC in an existing single-family

home. All measures are evaluated for cost effectiveness based on the lifetime benefits relative to

the cost of the measure. The total savings are ca lculated for each year of the model and depend

on the base year saturation of the measure, the applicability 3 

## of the measure, and the savings as

a percentage of the relevant energy end uses.

3 The applicability factors take into account whether the measure is applicable to a particular building type and whether it is feasible to

install the measure. For instance, attic fans are not applicable to homes without attics, and in some homes with attics, it may not be

feasible to install an attic fan because of lack of space.TVA Energy Efficiency Potential Study, Volume 2 Analysis Approach and Data Development

Screening Measures for Cost-Effectiveness

Only measures that are cost-effective are included in economic and achievable potential.

Therefore, for each individual measure, LoadMAP performs an ec onomic screen. This study uses

the total resource cost (TRC) test that compar es the lifetime benefits (both energy and peak

demand) of each applicable measure with its installed cost, which includes material, labor, and

administration of a delivery mechanism, such as an energy efficiency program. The lifetime

benefits are calculated by multiplying the annua l energy and demand savings for each measure

by all appropriate avoided costs for each year, an d discounting the dollar savings to the present

value equivalent. The analysis uses each measure’s values for savings, costs, and lifetimes that

were developed as part of the measure characterization process described above. For economic

screening of measures, incentives are not includ ed because they represent a simple transfer

from one party to another, but have no effect on the overall measure cost.

The LoadMAP model performs this screening dynami cally, taking into account changing savings

and cost data over time. Thus, some measures pass the economic screen for some — but not all

— of the years in the forecast.

It is important to note the foll owing about the economic screen:

• The economic evaluation of every measure in th e screen is conducted relative to a baseline

condition. For instance, in order to determine the kilowatt-hour (kWh) savings potential of a

measure, kWh consumption with the measur e applied must be compared to the kWh

consumption of a baseline condition.

• The economic screening was conducted only fo r measures that are applicable to each

building type and vintage; thus if a measure is deemed to be irrelevant to a particular

building type and vintage, it is exclud ed from the respective economic screen.

4 Note that saturation levels reflected for the base year change over time as more measures are adopted.TVA Energy Efficiency Potential Study, Volume 2 Analysis Approach and Data Development

Global Energy Partners 2-13

An EnerNOC Company 

## Table 2-7 shows the results of the economic screen for CAC for selected years, as well as results

for two interior lighting technologies. In 2012, the most cost-effective option is SEER 13.

However, in 2015, due to federal energy efficien cy standards, the SEER 13 unit goes off the

market and SEER 14 becomes the standard efficiency unit. In 2015 and beyond, the economic

screen selects the SEER 14 option because the ma rginal savings between th e standard efficiency

SEER 14 unit and the higher-efficiency options are not sufficient to make the higher-efficiency

units economical. The table also shows how th e economic choice for two of the lighting

technology options varies over the study period. If the measure passes the screen (has a benefitto-cost (B/C) ratio greater than or equal to 1.0), the measure is included in economic potential.

Otherwise, it is screened out for that year. If multiple equipment meas ures have B/C ratios

greater than or equal to 1.0, the most efficient technology is selected by the economic screen.

## Energy-Efficiency Potential

The approach we used for this study adheres to the approaches and conven tions outlined in the

National Action Plan for Ener gy-Efficiency (NAPEE) Guide for Conducting Potential Studies

(November 2007). 5 

## The NAPEE Guide represents the most credible and comprehensive industry

practice for specifying energy-efficiency potential. Specifically, four types of potentials were

developed as part of this study:

• Technical potential is a theoretical construct that assu mes the highest effi ciency measures

that are technically feasible to install are adopted by customers, regardless of cost or

customer preferences. Thus, determining the tec hnical potential is relatively straightforward.

LoadMAP “chooses” the most effi cient equipment options for each technology at the time of

equipment replacement. In addition, it installs all relevant non-equipment measures for each

technology to calculate savings.

For example, for residential central air conditio ning (CAC), as shown in Table 2-5, the most

efficient option is a SEER 21 system. If the technical potential scenario installs a SEER 21

unit, any non-equipment measure from Table 2-6 is then applied to the energy used by the

SEER 21 system to further reduce CAC energy use. LoadMAP applies the savings due to the

non-equipment measures one-by-one to avoid do uble counting of savings. The measures are

evaluated in order of their B/ C ratio, with the measure with the highest B/C ratio applied

first. Each time a measure is applied, the base line energy use for the end use is reduced and

the percentage savings for the next measure is applied to the revised (lower) usage.

• Economic potential results from the purchase of the most efficient cost-effective option

available for a given equipment or non-equipment measure as determined in the costeffectiveness screening process described above. As with technical potential, economic

potential is a phased-in approach. Economic po tential is still a hypothetical upper-boundary

of savings potential as it represents only measures that are economic but does not yet

consider customer acceptance and other factors.

for Change

## • Achievable potential defines the range of savings that is likely to occur.

o 

## Achievable – High reflects high awareness of effici ency options, minimal barriers to

customer adoption, best-practices program design, and incentives that represent a

substantial portion of the incremental cost combined with high administrative and

marketing costs.

o 

## Achievable - Low reflects lower awareness of en ergy efficiency options, lower

incentive levels and lower administrative and market costs.

The calculation of technical and economic potential is straightforward as described above. To

develop estimates for achievable potential , we specify adoption rates for each measure that

reflect the combination of market acceptance ra tes (MARs) and program implementation factors

(PIFs). We base the expected adoption rates on other relevant potential studies and market

research.



## Program Recommendations

In this final step, we review the potential esti mates by measure, customer segment, and sector

to develop a set of program recommendations for achieving the highest level of energy

efficiency. The results of this review are presented in Chapter 8.



# Data Development

Global Energy Partners Databases, Analysis Tools, and Reports

Global maintains several databases and modeling tools that we use for forecasting and potential

studies.

• Energy Market Profiles Database. Since the late 1990s, Global staff has maintained a

database of end-use profiles by sector, customer segment and region for electricity and

natural gas. The database contains market size, fuel shares/saturations, UECs/EUIs,

intensities, and total sales.

• Building Energy Simulation Tool (BEST) . Global’s BEST is a derivative of the DOE 2.2

building simulation model, us ed to estimate base-year UECs and EUIs, as well as measure

savings for the HVAC-related measures.

• Database of Energy Efficiency Measures (DEEM) . Global maintains a database of

energy efficiency measures for residential, co mmercial, and industrial segments across the

U.S. This is analogous to the DEER database developed for California. Global updates the

database on a regular basis as it conducts new energy efficiency potential studies.

• EnergyShape TM 

## Database . This database contains end-use load shapes for residential and

commercial segments for nine regions in the U. S. For the non-HVAC end uses, we used the

EnergyShape data to develop the peak factors that represent the fraction of annual energy

use that occurs during the peak hour. The peak factors were calibrated to available utility

data for the system peak. The final peak factors were applied to annual energy savings to

calculate the peak-demand sa vings from EE measures.

• Recent Studies . Global has conducted numerous studies of EE potential in the last five

years. We checked our input assumptions and an alysis results against the results from these

other studies, which include AmerenUE, Los Angeles Department of Water and Power,

Consolidated Edison of New York, Avista Utilities, the State of New Mexico, and Seattle City

Light. In addition, we used the information about impacts of building codes and appliance

standards from a recent report for the Institute for Energy Efficiency.

Energy Efficiency Measure Data

In addition to BEST and DEEM (described above), several other sources of data were used to

characterize the energy efficiency measures.

• Database for Energy Efficient Resources (DEER). The California Energy Commission

and California Public Utilities Commission (CPUC) sponsor this database, which is designed to

provide well-documented estimates of energy and peak demand savings values, measure

costs, and effective useful life (EUL) for the st ate of California. We used the DEER database

to cross check the measure savings we developed using BEST and DEEM.

o 

## The Census Bureau also provides a mapping of SIC to NAICS codes.

http://www.census.gov/eos/www/naics/

• California Statewide Surveys . The Residential Appliance Saturation Survey (RASS) and

the Commercial End Use Survey (CEUS) are comprehensive market research studies

conducted by the California Energy Commission. These databases provide a wealth of

information on appliance use in homes and bu sinesses. RASS is based on information from

almost 25,000 homes and CEUS is based on info rmation from a stratified random sample of

almost 3,000 businesses in California.

• Annual Energy Outlook . The Annual Energy Outlook (AEO), conducted each year by the

U.S. Energy Information Administration (EIA), presents yearly projec tions and analysis of

energy topics. For this study, we used data from the 2011 AEO.

• Electric Power Research Institute – Assessment of Achievable Potential from

Energy Efficiency and Demand Response Programs in the U.S. , also known as the

EPRI National Potential Study (2009). In 2009, EPRI hired Global to conduct an assessment

of the national potential for energy efficien cy, with estimates derived for the four DOE

regions (including the South region that includes the TVA territory).

• EPRI End-Use Models (REEPS and COMMEND) . These models provide the elasticities we

apply to electricity prices, household inco me, home size and heating and cooling.

Data Application for Market Profiles

To develop the market profiles for each segmen t, we used the following general approach:

1. Developed control totals for each segment. These include market size, segment-level

annual electricity use, and annual intensity.

2. Used TVA’s 2010 Residential Saturation Survey to incorporate information on existing

appliance and equipment saturations, appliance and equipment characteristics, and

building characteristics.

3. Incorporated secondary data sources to supp lement and corroborate the data from items

1 and 2 above.

4. Compared and cross-checked with regional data obtained as part of the EPRI National

Potential Study and with the Energy Market Profiles Database.

5. Ensured calibration to control totals for a nnual electricity sales in each sector and

segment.

6. Worked with TVA staff to vet the data against their knowledge and experience.

of 1.86%. Discount rates, line loss factors, av oided capacity, and avoided energy costs were

provided by TVA. Administrative costs were assumed to be 10% of incremental costs forTVA Energy Efficiency Potential Study, Volume 2 Analysis Approach and Data Development

## purposes of the measure level economic screen. Other program cost assumptions are made for

the portfolio cost effectiveness analysis discussed in Chapter 7.

Potentials Estimation

To estimate potentials, three sets of parameters were required.

• Adoption rates for non-equipment measures . Equipment measures are installed when

existing units fail. Non-equipmen t measures do not have this na tural periodicity, so rather

than installing all available non-equipment measures in the first year of the forecast

(instantaneous potential), they are phased in according to adoption schedules that vary

based on cost and complexity. The adoption rate s used in this analysis are based on expert

opinion and engineering review of how quic kly the market could absorb these measures.

Typically, measures that cause disruption to th e building, such as wall insulation in existing

buildings, receive longer adoption curves, while those with drop-in installations, such as

programmable thermostats in new buildings, rece ive shorter ones. Thes e adoption rates are

used within LoadMAP to generate the Technical and Economic potentials.

• Market acceptance rates (MARs) . These factors are applied to Economic potential to

estimate the upper bound: Achievable - High. Th e rates for this study were taken from the

EPRI National Potential Study and capped at 85% in the few instances where the factors

exceeded that number. This reflects nationwide estimates for all territories of the United

States, some of which have aggressive DSM efforts and high levels of engagement. It is

meant to comprise a high and aggre ssive upper bound on the potentials.

• Program implementation factors (PIFs) . These factors are applied to Achievable – High

potential to calculate Achievable – Low potent ial. These rates were developed from primary

market and attitudinal research in a recent potential study for AmerenUE in Missouri, a

region that faces similar challenges to DSM as the Valley: a short track record in DSM

programming, low energy prices, and a soci al consciousness less focused on energy

efficiency than some other areas in the country. This is meant to comprise a low bound on

the potentials.

MARs and PIFs are presented in Appendix E.Global Energy Partners 3-1

## CHAPTER 3



# MARKET CHARACTERIZATION AND MARKET PROFILES

The Tennessee Valley Authority (TVA) is the largest electric utility in the U.S. on the basis of

energy sales, with annual sales of 174 billion kWh in 2010. 8 

## TVA serves as the wholesale provider

for 155 power distributors and directly serves 59 industrial and federal facilities. Its service

territory, with an approximate area of 80,000 square miles, encompasses more than 9 million

people in seven southeastern states. It includes nearly the entire state of Tennessee as well as

portions of Alabama, Georgia, Kentucky, Mississipp i, North Carolina, and Virginia. Major cities are

Memphis, Nashville, Knoxville, Huntsville, and Chattanooga. The top indu stries in the service

territory are chemical products, primary metals, paper products, and food products.

Total electricity use for the residential, commerc ial and industrial sectors for TVA in 2009 was

147,949 GWh. 9 

## As shown in Figure 3-1, the largest sect or is residential, accounting for 42%, or

62,246 GWh. The remaining use is split between th e commercial and industrial sectors, at 39,561

GWh and 44,311 GWh respectively.

# Residential Sector

This section characterizes the residential market at a high level, and then provides a profile of

how customers in each segment use electricity by end use.

Total residential electricity use in 2009 was 62, 246 GWh. Customer information for each segment

is shown in Table 3-1 and Figure 3-2.The single-family segment used the vast majority of the

total residential sector electricity in 2009 as a result of the largest number of customers and the

highest intensity. The mobile home segment also has a high usage per customer, almost as high

as single family customers.

# Industrial Sector

The industrial sector, at 44,311 GWh in 2009, accounts for almost one-third of total electricity

sales. Chemical products, primary metals, paper pr oducts, and food products are the four largest

industries throughout the Valley, accounting for 59% of total industrial sales in 2009. In order to

capture measures that are specific to these industries we isolated them as separate segments,

while combining the remaining industries into the Other Industrial category.

As with the residential and commercial sector s, the industrial marke t profiles characterize

electricity use in terms of end use and technology for the base year 2009. Table 3-5 shows the

composite market profiles for the industrial sector.

## Figure 3-7 presents the end-use breakout for the industrial sector in 2009. Machine drive is the

largest overall end use for the industrial sector, ac counting for 52% of energy use. Note that this

analysis includes a wide range of industrial equipment, such as air compressors and refrigeration

compressors, pumps, and fans within the motors ca tegory. Since so many industrial applications

are unique and defy high-level classification sc hemes, the miscellaneou s category comprises the

second largest end use at 16% of industrial energy use. Process heating accounts for 11% of

energy use, while lighting, cooling, heating, and ventilation are all under 10%.

Figure 3-7 Industrial Electricity Use by End Use, 2009

Table 3-6 and Figure 3-8 show how the major industri al segments in the Valley used electricity in

2009. Machine drives dominate all segments, though process heating is more prevalent in the

primary metals segment.

## CHAPTER 4



# BASELINE FORECAST

Prior to developing estimates of energy-efficie ncy potential, a baseline end-use forecast was

developed to quantify how electricity is used by end use in the base year and what the

consumption is likely to be in the future in absence of new utility programs and naturally

occurring efficiency. The baseline forecast serves as the metric against which energy efficiency

potentials; technical, economic, and achievable, are measured. The baseline forecast we

developed for TVA was consistent with its official forecast from October 2011.



# Residential Sector

The baseline forecast incorporates assumptions about economic growth, electricity prices, and

appliance/equipment standards and building codes that are already mandated.

Figure 4-1 presents the baseline forecast at th e end-use level for the residential sector as a

whole. Overall, residential use increases from 62,246 GWh in 2009 to 82,830 GWh in 2030, an

increase of 33%, or an average growth of 1.4% per year.

Figure 4-1 Residential Baseline Forecast by End UseTVA Energy Efficiency Potential Stud y, Volume 2 Baseline Forecast

4-2 www.gepllc.com 

## Figure 4-2 presents the forecast of use per ho usehold. Most noticeable is that lighting use

decreases significantly after 2012, as the lighting standard from EISA comes into effect and as

LED lamps begin to gain traction in the later years of the forecast.

Figure 4-2 Residential Baseline Electricity Use per Household by End Use

Table 4-1 shows the end-use forecast at the technology level. Specific observations include:

1. The primary reason for the reduction in the base line forecast beginning in 2012 is the federal

lighting standards. The standard phases gene ral service incandescent lamps out of the

market over a three-year period. It causes a decline in interior screw-in lighting use by 38%

over the forecast period.

2. Cooling increases over the foreca st period due to higher saturations of central AC in new

construction, but only slightly due to moderating effect of forthcoming appliance standards.

3. Electric water heating has a high saturation relative to other areas around the country, but

grows only modestly over the forecast period, also offset by forthcoming appliance

standards.

4. Appliance energy use decrease markedly, reflecting efficiency gains from standards,

particularly in refrigeration appliances.

5. Growth in use in electronics is substantial and reflects an increase in the saturation of

electronics and the trend toward higher-powered computers. This is tempered somewhat by

the higher efficiency of televisions.

6. Growth in miscellaneous use is also substantia l. This use includes various plug loads not

elsewhere classified (e.g., hair dryers, power tools, coffee makers, etc.). This end use has

grown consistently in the past and we inco rporate future growth assumptions that are

consistent with the Annual Energy Outlook.TVA Energy Efficiency Potential Stud y, Volume 2 Baseline Forecast

# Commercial Sector

Electricity use in the commercial sector grows modestly at 13% overall during the forecast

horizon, an average of 0.6% per year. Usage st arts at 39,561 GWh in 2009, decreases until 2015

and then increases to 44,718 GWh in 2030. Figu re 4-3 and Table 4-2 present the baseline

forecast at the end-use level for the commercial sector as a whole. Most end uses show modest

growth over the forecast period. The exceptions are interior lighting, which declines due to the

EISA 2007 lighting standards, and refrigeration, which is affected by the EPACT 2005 standards

for refrigeration.

# ENERGY EFFICIENCY MEASURES

List of Energy Efficiency Measures

The first step of the energy efficiency measure analysis is to identify the list of all relevant

energy efficiency measures that should be co nsidered for the TVA potential assessment.

For this study, Global prepared a preliminary list of measures for TVA to review. After

incorporating feedback, we populated the full databases for the three sectors.

Sources for the measure assumptions were draw n from TVA’s Measurement Manual and latest

program evaluation results, Glob al’s building modeling tool BEST, and Global’s other measure

databases from previous studies and program work.

• Residential Measures . The residential measures span all end uses and vary

significantly in the manner in which they impact energy consumption. Table 5-1 shows

the residential equipment measure options and the segments for which they were

modeled. Table 5-2 shows the residential non- equipment measure options. All residential

measures considered for this stud y are described in Appendix B.

## CHAPTER 6



# ENERGY EFFICIENCY POTENTIAL

This chapter presents the results of the energy-ef ficiency analysis. First, the overall potential is

presented, followed by results for each sector.



# Overall Energy Efficiency Potential

Table 6-1 presents the baseline forecasts of en ergy consumption and peak demand, as well as

the levels of electric energy-efficiency potential across sectors. As discussed in detail in Chapter

4, the baseline forecast across all sectors increases over the 20-year study period of 2012 to

2031. The growth is highest in the residential sector, although all sectors have somewhat

tempered forecasts due to appliance and equipment standards, building codes, and a sluggish

economy in the near term. Key findings related to potentials are summarized below.

• Achievable - Low potential forms a lower point on the range of achievable potential.

Across all sectors, this metric is 3,256 GWh in 2015 and increases to 19,093 by 2030. This

represents 2.2% of the baseline forecast in 2015 and 10.6% in 2030. By 2030, Achievable –

Low offsets 55% of the growth in the baseline forecast. Peak demand savings from energyefficiency measures are 687 MW in 2015, which represents 2.1% of the baseline forecast of

demand forecast. 10



## • Achievable - High potential forms the upper bound on the range of achievable potential.

It is 7,494 GWh in 2015, which represents 5.0% of the baseline forecast. By 2030, the

cumulative savings are 35,781 GWh, 19.8% of the baseline forecast, for an annual average

of just over 1% per year. By 2030, Achievable – High completely offsets growth in the

baseline forecast. Peak demand savings are 1,5 90 MW in 2015, which represents 5.0% of the

baseline forecast of peak demand. By 2030, pe ak demand savings reach 9,007 MW, 23.5% of

the baseline peak demand forecast.

• Economic potential

, which reflects the savings when all cost-effective measures are taken,

is 12,418 GWh in 2015. This re presents 8.4% of the baseline energy forecast. By 2030,

economic potential reaches 44,821 GWh, 24.8% of the baseline energy forecast. Peak

demand savings are 2,759 MW in 2015, which re presents 8.6% of the baseline forecast of

peak demand. By 2030, peak demand savings reach 11,438 MW, 29.8% of the baseline peak

demand forecast.

• Technical potential

, which reflects the adoption of all energy efficiency measures

regardless of cost-effectiveness, is a theoretical upper bound on savings. In 2015, energy

savings are 15,347 GWh, or 10.3% of the baseline energy forecast. By 2030, technical

potential reaches 57,244 GWh, 31.6% of the ba seline energy forecast. Peak demand savings

are 3,159 MW in 2015, which represents 9.9% of the baseline forecast of peak demand. By

2030, peak demand savings reach 13,817 MW or 36.0% of the baseline peak demand

forecast.

## Figure 6-5 Residential Energy Efficiency Potential Forecast



## Residential Potential by Market Segment

Single-family homes in the Valley account for the majority of this sector’s total sales in the base

year and throughout the forecast. Similarly, sing le-family homes account for the largest share of

potential savings by segment, as displayed in Table 6-4, which shows results for 2015.

Table 6-5 shows the savings by end use and mark et segment in 2015. The segments are similar

in terms of the distribution of savings opport unities by end use, but there are a few notable

differences. Single-family homes have more exteri or lighting and so have more savings potential

for this end use. Similarly, single-family home s are more likely to have swimming pools and

therefore have more potential for savings in pool pumps (captured in the miscellaneous end

use). Multi-family homes have a relatively larger opportunity in home electronics and air

conditioning compared to single-family homes, reflecting an older appliance stock.

## Residential Potential by End Use, Technology, and Measure Type

Table 6-6 provides estimates of sa vings for each end use and type of potential. Focusing first on

technical and economic potential, there are si gnificant savings that are both possible and

economic in numerous end uses:

• Water Heating offers the highest technical potentia l, which reflects the across the boardinstallation of solar water heating. However, solar water heating does not become costeffective, using the study’s a ssumptions of equipment cost and avoided cost, during the

forecast period. The technology with the next highest efficiency is the heat pump water

heater (HPWH). HPWH’s are cost effective th roughout the entire study, and drive high

economic potentials as a result. Also included in water heating potentials are measures such

as faucet aerators and low flow showerheads.

• Cooling offers the second-highest technical pote ntial, which reflects across-the-board

installation of SEER 21 units in homes with central air conditioning, installation of room AC

units with a EER of 12 in homes with room AC, central AC maintenance, installation of

various insulation measures, installation of high-efficiency windows, and AC duct repair and

maintenance. However, these most efficient equipment options do not pass the economic

screen at any point during the forecast, nor do the higher levels of insulation. This results in

economic potential that is less than half of technical potential.

• Combined Heating/Cooling, or heat pumps, has similar potential to Cooling, and follows

similar dynamics. The Valley has a large number of all-electric homes with air-source heat

pumps, and therefore offers large amounts of energy efficiency potential in this category.

The technical potential implements ductless mini splits as the highest efficiency air-source

heat pump and EER 30 systems as the high est efficiency geothermal heat pump.

• Home electronics also offer substantial savings opportun ities. Technical potential reflects

the purchase of ENERGY STAR units for all technologies.

• Interior lighting offers the largest potential savings in the earlier half of the time horizon.

The lighting standard begins its phase-in starting in 2012, which coincides with the

availability in the market place of advanced incandescent lamps that meet the minimum

efficacy standard. The baseline forecast assumes that people will install both advanced

incandescent and CFLs in screw-in lighting app lications, and that traditional incandescent will

still make up one fifth of the market for specialty lighting and other applications that are

exempt from the lighting standard. For technical potential, LED lamps are the most efficient

option, starting in 2012. However, LED lamps do not pass the economic screen until late in

the time horizon, so CFLs dominate for most of the earlier years.TVA Energy Efficiency Potential Study, Volume 2 Energy Efficiency Potential

6-8 www.gepllc.com 

## • Appliances also have significant technical potent ial savings. This reflects both the

replacement of failed white-goods appliances with the highest-efficiency option and removal

of second refrigerators in appliance recycling programs.

Figure 6-6 focuses on the range of residential achievable potential in 2015 and 2030.

• Lighting equipment replacement accounts for th e highest portion of the savings in the near

term as a result of the efficiency gap between advanced incandescent lamps and CFL lamps.

• Water heating accounts for large savings in th e long term because heat pump water heaters

are found to be cost-effective.

• Electronics, appliances, and space conditioning measures also contribute significantly to the

savings.

## As described in Chapter 2, using our LoadMAP mode l, we develop separate estimates of potential

for equipment and non-equipment measures. Tabl e 6-7 presents Achievable – Low results for

equipment at the technology level and Table 6- 8 presents non-equipment measures for which

Achievable - Low potential is greater than zero. The majority of the savings come from the

equipment measures, with lighting and water heat ing leading the way. Electronics, heat pumps,

and pool pumps/heaters provide significant savings as well.

# Commercial Sector Potential

The baseline forecast for the comm ercial sector only gr ows slightly, which re flects the sluggish

near-term economy and forthcoming codes and standards. Nevertheless, the opportunity for

energy-efficiency savings is still significant for the commercial sector.

• Achievable - Low potential projects 985 GWh of energy savings in 2015 and 5,557 GWh

in 2030. This corresponds to 2.6% of the baseline forecast in 2015 and 12.4% in 2030. Peak

demand savings under Achievable - Low are projected to be 164 MW, 2.8% of the baseline

peak demand forecast, in 2015. The savings increase to 835 MW or 11.7% of the baseline

forecast by 2030.

• Achievable - High potential is 2,181 GWh in 2015, which represents 5.8% of the baseline

forecast. By 2030, the cumulative energy savings are 10,130 GWh, 22.7% of the baseline

forecast. In 2015, peak demand savings are 364 MW, which represents 6.2% of the baseline

forecast of peak demand. By 2030, peak demand savings reach 1,509 MW, 21.1% of the

baseline peak demand forecast.

• Economic potential , which reflects the savings when all cost-effective measures are taken,

is 3,475 GWh in 2015. This re presents 9.2% of the baseline energy forecast. By 2030,

economic potential reaches 12,142 GWh, 27.2% of the baseline energy forecast. Peak

demand savings in 2015 are 580 MW, which repres ents 9.9% of the baseline forecast of peak

demand. By 2030, peak demand savings reach 1814 MW, 25.3% of the baseline peak

demand forecast.

• Technical potential, which reflects the adoption of all energy efficiency measures

regardless of cost, is a theoretical upper bound on savings. In 2015, energy savings are

4,221 GWh, or 11.2% of the baseline energy fo recast. By 2030, technical potential reaches

16,053 GWh, 35.9% of the baseline energy fo recast. Peak demand sa vings are 651 MW in

2015, which represents 11% of the baseline forecast of peak demand. By 2030, peak

demand savings reach 2,278 MW or 31.8% of the baseline peak demand forecast.

## Commercial Potential by End Use, Technology, and Measure Type

Table 6-10 presents the commercial sector saving s by end use and potential type. The end uses

with the highest technical and economic potential are:

• Interior lighting, as a result of LED lighting that is now commercially available for screw-in

applications, has the highest technical potent ial at 1,632 GWh in 2015. Moreover, most of

the lighting equipment and measures are cost-effective resulting in economic potential of

1,561 GWh, which is 96% of technical potentia l. In the Achievable – Low case, roughly a

third of the economic potential, 525 GWh can be captured in 2015.

• Cooling has the second highest savings for te chnical potential at 614 GWh in 2015. These

savings result from installation of high-efficiency equipment and numerous thermal shell

measures, HVAC control strategies, and retroc ommissioning. Many of these measures are

cost-effective, resulting in economic potential savings of 249 GWh in 2015, or 40% of

technical potential savings. Achievable – Low potential is 53 GWh in 2015.

• Exterior lighting takes third place for technical potential savings at 529 GWh in 2015. The

savings result from LED lighting that is commerc ially available. Nearly all of these measures

are cost-effective, resulting in economic potential of 528 GWh in 2015. Achievable – Low

potential is 169 GWh in 2015.

Ventilation, office equipment, water heating, co mbined heating and cooling, and refrigeration

also have significant savings in terms of technical and economic potential. The savings potential

from space heating, food preparation, and miscellaneous uses are relatively small.

Table 6-10 and Figure 6-9 focus on achievable po tential savings. Figure 6-9 compares the range

of potential in 2015 and 2030. Not surprisingly, interior lighting delivers the highest achievable

savings throughout the study period. In 2015, exterior lighting is second, office equipment is

third, and ventilation and cooling are next highest in terms of Achievable - Low potential. In

2030, though interior lighting still provides the gr eatest Achievable - Low potential, cooling is the

second greatest source of savings, follow ed by refrigeration an d exterior lighting.TVA Energy Efficiency Potential Study, Volume 2 Energy Efficiency Potential

## Figure 6-9 Commercial Achievable Poten tial Savings by End Use in 2015 and 2030

Table 6-11 and Table 6-12 present achievable potential savings for equipment measures and

non-equipment measures, respectively, under the Achievable - Low case. The greatest savings in

the near term (2015) come from:

• Replacement of interior lighting systems (279 GWh, 139 GWh, and 99 GWh respectively for

screw-in, high bay, and linear fluorescent lighting systems)

• Installation of Energy Management Systems (155 GWh)

• HVAC equipment maintenance programs (155 GW h for AC maintenance and 36 GWh for heat

pumps)

• Refrigerator decommissioning and recycling (134 GWh)

• Replacement of exterior lighting systems (97 GWh, 68 GWh, and 3 GWh respectively for

screw-in, HID, and linear flu orescent lighting systems)

Together, these five categories of measures account for 1,166 MWh, roughly 62% of the

Achievable - Low potential savings in the commercial sector in 2015. By 2030, non-equipment

measures play a greater role in potential, le d by energy management systems, refrigerator

decommissioning, and roof-top equipment maintenance.TVA Energy Efficiency Potential Study, Volume 2 Energy Efficiency Potential

## Figure 6-10 Achievable Potential Savings in 2015 by Commercial Building Type

Table 6-14 and Table 6-15 present the achievab le potential for 2015 by measure and building

type. Lighting replacement and upgrade, particularly for screw-in lamps, is a key measure across

all buildings. In the near term, lighting predominates, but other key measures for each building

type are as follows:

• Retail: water heating and ventilation

• Offices: office equipment, ventilation, cooling equipment upgrades, and energy

management systems

• Restaurants: water heating with HPWH, food preparation equipment, and refrigeration

upgrades

• Grocery: refrigeration, particularly walk-in refrigeration, and water heating

• Warehouse: refrigeration equipment upgrades

• Schools: ventilation, office equipment, HPWH water heating equipment, and HVAC

maintenance

• Colleges: ventilation, office equipment, and HPWH water heating equipment

• Health: ventilation, Energy management system s, variable speed drives on chillers, chiller

upgrades, and office equipment

• Lodging: Heat pump and RTU equipment upgrades and maintenance, ventilation, and

office equipment

For many building types, energy management sy stems become a significant source of energy

potential over the longer term.TVA Energy Efficiency Potential Study, Volume 2Energy Efficiency Potential6-22www.gepllc.com Table 6-14 Commercial Achievable Savings from Equipment Measures in 2015 by

# Industrial Sector Potential

The industrial sector, at 44,311 GWh in 2009, accounts for almost one-third of total electricity

sales. Chemical products, primary metals, paper pr oducts, and food products are the four largest

industries throughout the Valley, accounting for 59% of total industrial sales in 2009. Because of

their size, and in order to capture measures that are specific to these industries, we isolated

them as separate segments.

Most of the equipment replacement opportunities ar e in the machine drive (motors) end use, but

potential savings are diminishing due to the National Electrical Manufacturer’s Association

(NEMA) standards, which now make premium efficien cy motors the baseline efficiency level. As a

result, potential savings are only available from upgrading to still more efficient levels.

Furthermore, due to the site-specific nature of many industrial sector process energy efficiency

opportunities, savings potential resulting fr om these customized ap proaches should be

characterized individually. To understand these opportunities in more depth, it would be

appropriate to carry out site-specific engineering assessments for each customer, though we

would recommend that such assessments be li mited to only the very largest customers.

Throughout the study period, Economic potentia l is about 80%–90% of Technical potential,

indicating that most of the measures evaluate d are cost-effective. In 2015, Achievable - Low

potential is 826 GWh or 1.7% of the baseline indu strial forecast. By 2030, it increases to 5,229

GWh, or 9.8% of the baseline forecast and 43% of economic potential. Table 6-16, Figure 6-11

and Figure 6-12 present the savings for the various types of potential considered in this study.

## Industrial Potential by End Use

Table 6-17 presents the industrial savings by end use and type of potential. As mentioned above,

machine drives offer the greatest opportunity fo r energy savings across the range of potential.

Lighting has the next highest savings potential, pa rticularly in the near term, but is ultimately

dwarfed in comparison to the opportunities for machine drives.

## Figure 6-13 illustrates the range of achievable potential savings by end use in 2015 and 2030 for

the industrial sector, reinforcing the dominance of the machine drive category. Beyond the

replacement of motors and lighting, particularly high bay fixtures, with more efficient units, the

specific measures that account for the larg est savings in the indu strial segment are:

• Integrated plant energy management — 45 MWh and 392 MWh of Achievable – Low

potential in 2015 and 2030 respectively

• Fan and pump system measures, which include system optimization, energy

management, and equipment upgrades — 135 GWh and 1,425 GWh of Achievable – Low

potential in 2015 and 2030 respectively

## CHAPTER 7



# COST-EFFECTIVENESS ANALYSIS

Financial Impacts

An important result from the analysis is the financial impact of the achievable potentials,

including utility program spending. Each energy efficiency measure has an incremental cost

relative to the cost of doing nothing or choosin g standard, baseline equipment. This incremental

cost, also known as the measure cost, is born by the customer, the utility, or a combination of

the two.

When a utility or program administrator is expending marketing or administrative dollars to

facilitate the implementation of measures, this cost must also be considered. The sum of the

measure cost and the program costs results in the total resource cost (TRC). An alternative cost

metric is the utility cost (UC), which is the total of the program costs and only the utility

incentive portion of the measure cost. The UC omits the customer-funded portion of the measure

cost, and therefore gives an estimate of th e dollars a utility will have to budget.



## Program Cost Assumptions

The LoadMAP model returns values for measure incremental cost, but assumes nothing about

incentive levels and therefore utility costs. Be cause program delivery costs can vary widely

depending on delivery mechanism and incentive level, the following analysis of cost-effectiveness

makes assumptions about what those costs will be for the Achievable- Low and Achievable –

High potential cases. For planning purposes, utility administrative and marketing costs are

commonly expressed as a percenta ge of incremental measure cost s. The assumptions used for

this analysis are shown in Table 7-1.

Table 7-1 Utility Program Cost Assumptio ns as % of Incremental Measure Cost

Achievable (Low) Achievable (High)

Incentive 50% 90%

Administration & Marketing 20% 30%

Total Program Cost 70% 120%

Note: The LoadMAP model currently includes a 10% admi nistrative cost adder when running the economic

screen, but higher values are applied for the analysis in this section.



## With these assumptions, financial impacts can be de veloped to estimate the utility budget required to

attain the achievable potentials. As shown in Table 7-2 and Figure 7-1, the resulting 2012 utility

budgets can range from $129 million for the Achiev able – Low portfolio up to $713 million for the

Achievable – High portfolio. In 2030, the range of annual budgets is $1.2 and $4.4 billion. This aligns

with the fact that some energy efficiency measures are more expensive than others, and lie along a

supply curve of ascending cost for each incremental un it of energy saved. Simply put: to save more

costs more.TVA Energy Efficiency Potential Study, Volume 2 Cost-Effectiveness Analysis

## A metric commonly used by utilities to track the efficacy of their programming efforts over time

is dollars spent per first-year-k Wh. The savings attained in that year are associated with a

certain budget in that year, and benchmarked across time and against other utility programs.

This is a preferred metric for program implementation staff who are interested in an immediate

time slice. Table 7-2 and Figure 7-2 include cost per first-year kWh results for the two

Achievable potential cases.

Figure 7-2 Utility Cost per First-Year kWh ($2009)

Another benchmark and indicator of program cost-effectiveness is the levelized cost of saved

energy over the lifetime of EE measures. This metric is often preferred by long-term resource

planners. The levelized cost is calculated as the net present value of the lifetime costs divided by

the lifetime energy savings resulting from the program. Another way to look at it is to find the

annual payment of amortizing the cost of a measure over its lifetime and dividing it by the

annual kWh savings. The levelized costs for the ra nge of achievable potentials are given in Table

7-3.

# Cost-Effectiveness Tests

Obtaining financial impacts allows us to perform industry standard cost-effectiveness tests. Each

test compares the benefits of the EE programs, defined as the lifetime avoided costs of saved

energy and peak demand in a net present value format, with its own unique definition of costs.

The cost definitions for the three tests most co mmonly used by utilities are described below.

• Total Resource Cost test (TRC). The total resource costs, as described above, are the

incremental measure cost (both utility and cu stomer portions) plus the program delivery

costs; all in a net present value format.

• Utility Cost Test (UCT). The benefits of the UCT test are the same as those in the TRC

test. The costs are the net present value of all program delivery costs and utility incentive

costs.

• Rate Impact Measure test (RIM). The RIM costs are the same as the UCT, except for the

addition of lost revenue. This attempts to show the effects that EE programs will have on

rates, which is almost always to raise them on a per unit basis. Thus, costs typically

outweigh benefits from the point of view of this test, but the assumption is that absolute

energy use decreases to a greater extent than per-unit rates are increased — resulting in

lower average utility bills.

The results for the three cost-effectiveness test s under the Achievable – Low and AchievableHigh scenarios appear in Table 7-4:

# PROGRAM RECOMMENDATIONS

The results of the EE assessment reveal that TVA has significant potential for energy efficiency

resources over the next two decades. Our analysis has shown that TVA can realize an achievable

range of reductions between 10.4% and 19.4% of the baseline forecast in 2030 with the

measures represented in this report.

TVA’s energy-efficiency programs are off to a strong start, with a comprehensive suite of

programs currently moving from the planning phas e to the implementation phase. Based on this

study, Global provides the following recommendat ions to preserve and augment that momentum.



# General Recommendations

• Coordinate distributor layer between TVA and end-user: As a wholesale provider for

155 power distributors, TVA’s business landscape poses unique challenges for the

administration of energy efficiency programs. Because of this arm’s-length relationship with

end users, TVA does not have the same leve l of information about customers as other

utilities. TVA will need to coordinate closely with its power distributors. To facilitate better

coordination, TVA should consider the hiring an d training of dedicated personnel to serve as

liaisons with the distributors.

• Maintain transparent stakeholder process: To date, TVA has been transparent and

aboveboard with internal and ex ternal stakeholders. Continuing to involve stakeholders and

cultivating a mutual understanding of continuo us improvement is of paramount importance

to the future success of programs. We reco mmend an open and tr ansparent stakeholder

process with regular touchpoints and workshops. Suggested workshop topics are: technical

resource manual with deemed measure database s; evaluation, measurem ent, and verification

protocols; emerging technolo gies; innovative program strategies; periodic reviews of

program results; and sharing success stories from individual power distributors or customers.

• Create internal EE targets: TVA should continue to evolve and formulate its specific

objectives regarding energy e fficiency by creating targets and goals. Global recommends

targets that fall within the range of achievab le potentials identified in this study.

• Aggressively pursue lighting savings in the near-term: Lighting represents a bulk of

the low-hanging fruit in the near term, with significant untapped potential in all sectors.

Programs have not yet aggressively targeted lighting, beyond a limited CFL giveaway effort.

Working upstream with trade allies and retailers will likely yield significant savings. In

particular, as the EISA standards take effect, educational programs and coordination with

retailers can help customers move beyond EISA -compliant lamps to more efficient CFL and

LED technologies.

• Create targeted marketing messages: Energy prices in the Va lley are cheaper than the

national average. Correspondingly, the custom er base does not have a long history of

exposure to marketing and education regarding energy and sustainability issues like other

jurisdictions around the nation . As a result, customers have not been strongly driven to

consider energy efficien cy measures, and awareness and adopti on will be lower than national

averages at first. Targeted marketing and education efforts should be developed with

messages that speak to the customer ba se and cultivate shared attitudes.

• Expand knowledge of the customer base: TVA’s pre-existing data regarding the

customer base is minimal. Opportunities should be explored to expand this knowledge base.

Not only will this information be valuable for program efforts, the results can be shared with

distributors, many of whom are too small to conduct surveys on their own. Surveys shouldTVA Energy Efficiency Potential Study, Volume 2 Program Recommendations

8-2 www.gepllc.com 

## collect data in all sectors on end use equi pment saturations, customer attitudes, and

measure penetration.



# Residential Recommendations

• Pursue CFLs: Significant, cost-effective potential is available with CFLs, in spite of the

forthcoming EISA standards that will reduce their per-unit savings compared to the new

baseline. Also, TVA should focus strong attent ion on specialty CFL programs, as these bulbs

are not addressed in the EISA standard.

• Focus on all-electric homes: The prominence of all-electric homes, roughly 50%, has

many implications for program design. Audit pr ograms with direct in stall measures are one

mechanism for reaching these customers. New co nstruction incentives can help to boost the

penetration of heat pumps, heat pump water heaters (HPWH), and advanced construction

designs.

• Pursue heat pump water heaters: Heat pump water heaters offer significant potential,

but educational efforts, for trade allies as we ll as homeowners, will be required to achieve

this potential. Consider bundling HPWH with the existing and establis hed space conditioning

heat pump program to take advantage of the gains the heat pump programs have made in

acquainting trade allies and targeted part icipants with heat pump technology.



# Commercial and Industrial Recommendations

• Pursue lighting savings: Strongly pursue lighting savings to accelerate the phase out of

T12 fluorescent lighting. In particular, program efforts can help intercept building operators

before they make purchase and stocking decisions that could lead to the hoarding of T12

lamps.

• Create customized, multi-year plans for large, complex customers : For large enough

customers, large success can be obtained with strategic energy management (SEM) 11



## initiatives over longer time horizons. This me ans a larger tracking an d time commitment, but

many jurisdictions are finding this to be a more effective method than a “one and done”

installation and rebate approach. These relationships involve personalized plans,

identification of metrics, goal-setting, technical assistance, and attention from account

executives.

• Focus program efforts on motor controls and system optimizations: Low-cost

retrofits can have significant, low-cost energy impacts with minimal disruption (and often

times improvement) of business processes.

# COMPARISON OF PREVIOUS POTENTIAL STUDIES

Previous studies of energy efficiency potential for the Valley and for the southeast region have

produced a range of results. As part of this potential assessm ent, TVA requested that Global

develop a comparison of several key recent studie s to better understand how the studies differ in

their approaches and thus why their results differ as well. Table 9-1 presents an at-a-glance

comparison of this study with other relevant studies of the southeast and the nation as a whole.

# Tennessee Valley Authority Energy Efficiency and Demand Response

Potential Study — Global TVA (This Study)

We begin by briefly summarizing our own study in the same manner as we will summarize the

comparison studies. The Global TVA study wa s conducted in 2011. It estimated EE and DR

savings specifically for the TVA service territory. The base year for the study was 2009 and the

forecast horizon was 2009 through 2030, with program activity beginning in 2012. The

contractors for the study were Global Energy Partners and The Brattle Group.

Analysis approach: The study used a bottom-up analysis approach 13 

## . Analysis was performed

at the sector, segment, end use, technology, and measure levels. TVA survey data, national

surveys (RECS, CBECS and MECS), and previous Global studies provided the inputs to the baseyear market characterization and end-use market profiles.

Baseline forecast: The study was grounded in the 2011 Annual Energy Outlook, but the

forecast was developed independent of it for the TVA region specifically. It includes the effects of

building codes and appliance standards in place in 2010, most notably the EISA lighting

standard. The baseline does not include naturally occurring efficiency.

Levels of potential: Technical and economic potential were developed, as well as a range of

achievable potentials: between Achievable – Low and Achievable High. Economic potential was

assessed using the total resource cost (TRC) test . Achievable – High represents a theoretical

upper bound of what could be achieved through utility programs. Achievable – Low represents a

lower and more moderate estimate of achievable potential.

Study Findings: Table 9-2 and Figure 9-1 summarize the energy-effi ciency savings for the

different levels of potential relative to the baseline forecast. Table 9-3 summarizes the range of

achievable potential by sector. The residential sector accounts for the largest portion of the

savings, and the commercial and industrial have sl ightly lesser savings with similar magnitudes to

each other.

# Assessment of Achievable Potential fr om Energy Efficiency and Demand

Response Programs in the U.S. (2010–2030) — EPRI National, South

Region

The EPRI National study was conducted in 2007–2008 and published in January 2009. It

estimated EE and DR savings for the U.S. as a wh ole and for each of the four census regions.

The base year for the study was 2008 and the forecast horizon was 2010 through 2030. The

contractors for the study were Global Energy Partners, LLC and The Brattle Group.

Analysis approach: The study used a bottom-up analysis approach 14 

## . Analysis was performed

at the sector level for each of the four census regions. The national surveys (RECS, CBECS and

MECS) provided inputs to the base-year market characterization and end-use market profiles.

Baseline forecast: The study was grounded in the 2009 Annual Energy Outlook and this

forecast was replicated in the modeling tool and was used as the baseline forecast. It included

the effects of building codes and appliance standards in place in 2008, the most recent of which

was the EISA lighting standard, as well as the effects of naturally occurring conservation.

Levels of potential: Four levels of potential were deve loped: technical potential, economic

potential, maximum achievable potential (MAP), and realistic achievable potential (RAP).

Economic potential was assessed using the partic ipant test. MAP represents a theoretical upper

bound of what could be achieved through uti lity programs. RAP represents a more moderate

estimate of achievable potential.

Study Findings: The study findings for the South region, which is the region in the report that

includes the TVA service territory, are summarized in Table 9-4 and Table 9-5.

Comparison to Global TVA Study: This study is reasonably comp arable to the Global study,

but shows lower potential. It employed a bottom- up modeling with a stock-accounting/turnover

algorithm like the Global study. The baseline forecast was based on the AEO 2009 forecast

(1.0% national annual growth) and also includes the effects of important codes and standards

such as the EISA lighting standard ; although it does not include some of the newest ones, such

as the appliance standards of 2010. The study has regional specificity for the South, although it

## is not singularly focused on the TVA service territory, unlike the Global study. A factor that tends

to make potential estimates from the EPRI nation al study lower than the Global TVA study is the

inclusion of naturally occurring efficiency in EP RI’s baseline, which was not done in the Global

study. Also, EPRI assumes that all the technology used in the study must be commercially

available in the base year. This will limit the po tential available in many forthcoming, cuttingedge technologies that are included in the Global study, such as advanced incandescent 3.0 in

2020 and SEER 21 air conditioners.



# Assessment of Achievable Potential fr om Energy Efficiency and Demand

Response Programs for the Tennesse e Valley Authority (2010-2030) —

EPRI TVA

For this study, completed in March 2010, EPRI began with the analysis framework used for the

EPRI National Study and applied it to TVA by updating market data to the extent possible with

TVA data. The base year for the study was 2006 and the forecast horizon was 2010 through

2030. The contractors for the study were EPRI and Energy Resource Economics, LLC.

Analysis approach: The study used a bottom-up analysis approach, much like the National

Study. Potential estimates were developed at the TVA system level, by TVA district, by customer

sector (residential, commercial and indu strial), by end use, and by measure.

Baseline forecast: EPRI developed a baseline forecast using its stock-turnover model. It

included the effects the EISA lighting standard.

Levels of potential: Four levels of potential were deve loped: technical potential, economic

potential, maximum achievable potential (MAP ) and realistic achievab le potential (RAP).

Economic potential was assessed using the partic ipant test. MAP represents a theoretical upper

bound of what could be achieved through uti lity programs. RAP represents a more moderate

estimate of achievable potential.

Study Findings: The findings from the study are summarized in Table 9-6 and Table 9-7.

## effects of codes and standards such as the EISA lig hting standard, although it does not include some

of the newest ones, such as the appliance standards of 2010. The stud y has geographic specificity for

TVA’s territory. A factor that will tend to make th e potential from the EPRI TVA study lower than the

Global TVA study is the inclusion of naturally occu rring efficiency in EPRI’s baseline, which was not

done in the Global study. Also, EPRI assumes that all the technology used in the study must be

commercially available in the base year. This will lim it the potential available in many forthcoming,

cutting-edge technologies that are included in the Global study, such as advanced incandescent 3.0

in 2020 and SEER 21 air conditioners.



# Meta-Review of Efficiency Potential St udies and Their Implications for the

South — Georgia Tech Meta-Study

This study is a meta-review of 19 other potential studies focused in and around the Southern

United States in the years prior to the report. Several of the studies covered in the Georgia Tech

Meta-Study are also covered separately in this comparison: namely th e EPRI National, SEEA,

REPP, McKinsey, and North Carolina ACEEE studies. From these studies, the Georgia Tech MetaStudy collects more than 250 estimates of potent ial for different fuels, sectors, and potential

types. The study was published by the Georgia Institute of Technology’s School of Public Policy

in August, 2009.

Analysis Approach: The study performs no analysis; rather is simply surveys and groups other

studies’ analyses. Potential estimates were developed over 2010 to 2030.

Study Findings: The findings for average annual electric savings from the meta-study are

summarized in Table 9-8 below and compared with the relevant Global numbers in Figure 9-2.

Because no time horizon is given by the meta st udy, the Global numbers are annualized for both

10 years and 20 years. Potential studies can be highly dependent on the length of years

considered, as more low-hanging fruit is ty pically available in near-term analyses.

## Figure 9-2 Comparison of Georgia Tech Meta Study with Global Study

Comparison to Global TVA Study: All told, the meta-study aligns favorably with the results of the

Global study, especially when considering the aver age savings in the first 10 years of the Global

study. One can note that the MAP or Achievable – High metric is very similar between the studies,

but Global shows a lower RAP or Achievable – Low me tric; thus indicating that Global defines a wider

range of potential than that defined by the average values of the meta-study.



# Energy Efficiency in the South — Georgia Tech

This report presents energy effi ciency savings potential for the south over the next 20 years for

the residential, commercial, and industrial sect ors. The study was published by the Southeast

Energy Efficiency Alliance (SEEA) in April, 2010. The contractors for the study were Georgia

Institute of Technology and Duke University.

Analysis Approach:The study employed a hybrid approach using both “bottom-up” and “topdown” modeling features. For the “bottom-up” ap proach, the study used a modified version of

the National Energy Modeling System (NEMS) for its analysis. For the “top-down” approach, it

used Global Insight’s macroeconomic model. In ad dition to potential estimation, the study also

estimated macroeconomic impacts and developed su pply curves for a set of policy options. Costeffectiveness assessment was based on the Total Resource Cost test. Potential estimates were

developed over 2010 to 2030.

Baseline forecast: The baseline forecast of energy consum ption for the South, its three Census

Divisions, the 16 individual states, and the District of Columbia were derived from the updated

Annual Energy Outlook 2009 reference projections. This Reference Scenario forecast takes into

account the Economic Stimulus Package 2009.

Levels of potential: The study reported results for program achievable potential . It should be

noted that these potential estimates include op portunities that are not typically bundled in

energy efficiency studies, such as combined heat and power (CHP) and top-down policy options

such as building code expansion. These factors wi ll tend to produce higher potential relative to

other studies that do not include them.TVA Energy Efficiency Potential Study, Volume 2 Comparison of Previous Potential Studies

9-8 www.gepllc.com 

## Study Findings: The findings from the study are summari zed in the table below. Please note

that the savings indicated are for total primary energy consumption.

Table 9-9 Savings Potential by Sector – Georgia Tech

Potential

Estimates Cumulative Savings in 10 Years

(% of baseline forecast) Cumulative Savings in 20 Years

(% of baseline forecast)

Residential 9% 13%

Commercial 12% 18%

Industrial 11% 16%

Total 12% 16%

Comparison to Global TVA Study: The study baseline forecast is reasonably based on the AEO

2009 forecast, and the study has overall regional sp ecificity, but comparisons with the Global study

should be made mindfully. The first 10 years show higher achievable potential than the Global study,

while the second 10 years are at the very upper end of the Global achievable range. The Georgia

Tech study employs a hybrid bottom-up/top-down mo deling approach that will have higher potential

due to the inclusion of policy options like CHP and bu ilding codes. These effects are not included in

Global’s potential.



# Unlocking Energy Efficiency in the U.S. Economy — McKinsey

This report was published by McKinsey & Compan y in July, 2009. It estimates the total energy

savings potential for the United States over the 2008–2020 timeframe based on deploying a

variety of energy efficiency measures in the resi dential, commercial, and industrial sectors. The

study also identifies the barriers to achieving the potential and outlines strategies for overcoming

these barriers.

Analysis approach: The study developed a set of busi ness-as-usual choices for end-use

technologies using EIA’s modeling system and the Annual Energy Outlook 2008 as a foundation.

In order to identify energy-saving opportunities, the study modeled deployment of 675 energysaving measures and selected those that had a po sitive Net Present Value (NPV) over the lifetime

of the equipment. Costs included equipment capital and installation costs, O&M costs, and direct

energy costs.

Baseline forecast: The study was grounded in the 2008 Annual Energy Outlook and this

forecast was replicated in the modeling tool and was used as the baseline forecast.

Levels of potential: The analysis developed a “NPV-positive” potential for energy efficiency,

which selects end-use technologies with mini mum positive NPV values over the equipment

lifetime. Unlike traditional potential studies, it do es not define technical and achievable levels of

potential estimation. However, it estimates potent ial under alternative scenarios with variations

in assumptions related to discount rates, energy retail prices, and carbon prices. As such, these

results are most consistent with the economic pote ntial estimated in traditional potential studies.

That is, it does not consider customer, market, or regulatory barriers to achieving potential.

Study Findings: Overall, the study estimated 23% energy savings potential by 2020. Out of the

total, the residential sector contribution is esti mated at 35%, industrial sector contribution at

40%, and commercial sector contribution at 25%. It also presents an energy efficiency supply

curve for 2020 using estimates of average cost for end-use energy savings and the potential

associated with the various end uses.

Comparison to Global TVA Study: Comparisons between the McKinsey and Global study should

be made mindfully. The first caveat is that McKinsey is considering all forms of energy usage, and not

just electricity. The second caveat is that McKins ey uses its own version of “NPV-positive” potentialTVA Energy Efficiency Potential Study, Volume 2 Comparison of Previous Potential Studies

## that is unique in the industry. The baseline forecast is based on AEO 2008 (1.1% national average

annual growth). The forecast includes the EISA light ing standard, which is consistent with the Global

study.



# Energy Efficiency in Appalachia “How Much More is Available, at What

Cost, and by When?” — SEEA

This report was published by the Southeast Energy Efficiency Alliance in March 2009. The

contractors for the study were Georgia Institute of Technology and the American Council for an

Energy Efficient Economy (AC EEE). The Appalachian Regional Commission (ARC) commissioned

this study to assess long-term energy efficie ncy potential for the Appalachian region by

introducing advanced energy effi ciency standards for each energy end-use sector, and also to

estimate the economic and environm ental impacts of these standards.

Analysis approach: The study assumes a set of “trans formative energy policies” in the

Appalachian region, beginning in 2010, in order to assess the magnitude of cost-effective and

achievable energy efficiency improvements in Appalachia. The policy portfolio modeled in the

report includes a combination of Research, Development, and Demonstration (RD&D) and

technology-deployment activities developed thro ugh a stakeholder approach. It estimates costeffective energy-efficiency savings for four end-use sectors (residential, commercial, industrial,

and transportation) using a set of policy bundles for each sector. It uses participant cost test and

total resource cost test to assess cost-effectiv eness under different carbon and energy price

scenarios. The results of these policy analyses are then input into a dynamic input-output model

to evaluate the macro-economic impacts of pr oposed policies. The study considers a 25-year

time horizon from 2005-2030.

Baseline forecast: The study uses EIA’s business-as-usual scenario in the 2008 Annual Energy

Outlook as the baseline forecast.

Levels of potential: The study estimates program potent ial associated with cost-effective

energy-efficiency improvements th at would occur in response to specific policies such as

subsidies and information dissemination.

Study Findings: Overall, the study estimated 11% energy savings potential by 2020 and 24%

energy savings over baseline forecast in 2030. The commercial sector share at 42% accounts for

the largest contribution in overall energy savings potential in 2030. Next, industrial sector share

is estimated at 25%, followed by transportation at 18%, and residential at 15%. The study also

estimates savings potential by fuel type. The el ectricity system is estimated to have a 68%

share, followed by motor gasoline at 17%, and natural gas savings at 12%. Additionally, the

study also estimates economic and job impa cts associated with these energy savings.

Comparison to Global TVA Study: Comparisons with the Global study should be made mindfully.

The SEEA study employs a high-level, top-down mo deling approach, which is fundamentally different

from the Global approach. Additionally, the SEEA energy savings include transportation and natural

gas, as well as policy options like CHP and building co des. These effects are not included in Global’s

potential.



# Powering the South: A Clean & Affordable Energy Plan for the Southern

United States — REPP

This study was published in 2002. The report provides estimates of energy efficiency savings

potential for the Southern region (SERC and FR CC) with recommendations on specific policy

options to achieve those savings. In addition to energy efficiency, the report also recommends

policy options for the region to advance the pene tration of renewable energy. The base year for

the study was 2000 and the forecast horizon was through 2020.

The contractors for the study were staff from th e Renewable Energy Policy Project and Synapse

Energy Economics.TVA Energy Efficiency Potential Study, Volume 2 Comparison of Previous Potential Studies

9-10 www.gepllc.com 

## Analysis approach: The PROSYM model 15 

## was used to simulate the power system in the south

(including the SERC and FRCC regions) under two scenarios: Business as Usual and Clean Power

Plan. The modeling was done at the state level. Analysis results are presented for Alabama,

Florida, Georgia, North Carolina, South Caroli na, and Tennessee. First the Business as Usual

scenario was constructed based on the AEO 2001 forecast. Next, the Clean Power Plan scenario

was analyzed. It included a set of energy e fficiency measures and renewable resources.

Baseline forecast:The study was grounded in the 2001 Annual Energy Outlook (Business-asUsual case).

Levels of potential: One level of potential was estimated in the Clean Power Plan, which

assumed aggressive implementation of energy efficiency measures.

Study Findings: As part of the Clean Power Plan, the st udy recommended a set of policies to

advance energy efficiency and renewable energy, and to curb pollution. It also provides a few

specific recommendations for TVA, outside of thes e policies. Savings results, indicated in Table

9-10, are presented by sector.

Table 9-10 Savings Potential by State – REPP

Sector Electricity Savings 2002–2010 Electricity Savings 2002–2020

Residential 13.5% 22.0%

Commercial 13.6% 22.9%

Industrial 14.5% 26.9%

Total 13.5% 22.9%

Comparison to Global TVA Study – Comparisons with the Global study should be made with a

high degree of caution. This is an older study wi th outdated technology and cost assumptions. The

baseline forecast is based on AEO 2001, which does not include the EISA lighting standard, as it was

ratified six years after the release of the study. Additionally, the high-level, top-down modeling is

very different from that employed by the Global study.



# Tennessee Valley Authority: Energy Efficiency and Demand Response Plan

2008 — PA Consulting

This study was published in 2008. It estimate d EE and DR program savings for TVA. The base

year for the study was 2007 and the forecast horizon was 2009 to 2030.

Analysis approach: The study’s goal was to determine th e potential for demand response and

energy efficiency programs that will reduce summer peak demand by 2012 at a cost equivalent

or less than a supply-side option . It estimated monthly electricity use by sector and end use

using a set of energy models. The energy usage was normalized using weather data. EE

technologies and DR options were applied to the energy use to develop estimates of potential.

The study also estimated levelized costs for each of the programs implemented through 2012. It

identified the critical success factors and key challenges associated with achieving the savings.

Along with potential estimation, the study also presented program designs for both EE and DR.

Baseline forecast: The baseline forecast was developed us ing TVA-provided data for its service

territory. The base year for the study was 2007.

Levels of potential: The study estimated technical, economic, and program potential:

• Technical potential was developed by applying assumptions related to technically feasible

energy efficiency improvements to every residential and non-residential building served by

## the TVA distributors. It also considered extensiv e application of site-based solar technologies.

It did not include efficiency improvements fo r direct-serve customers and fuel-switching

applications. Also, the technical potential estima tion did not include the effect of any demand

response options.

• Economic potential was developed by applying supply curves derived from a meta analysis of

other studies. Otherwise, the study did not fo llow a detailed economic potential development

approach.

• In addition to the economic and technical pote ntial, the study estimated program potential in

terms of summer and winter peak demand reductions, and annual energy savings. The study

also provided total program costs along with per unit levelized program costs over

2009-2012.

Study Findings: The study estimated energy savings of nearly 12 TWh by 2020 and more than

19 TWh by 2030, as shown in Table 9-11.

Table 9-11 Savings Potential Summary – PA Consulting

Program Potential Cumulative Savings

Energy Savings (GWh) 11,688 19,473

Summer Peak Reduction (GW) 4.3 6.0

Winter Peak Reduction (GW) 4.1 7.9

Comparison to Global TVA Study: The PA Consulting plan specifically targets the TVA territory.

The baseline was developed by TVA and PA Consulting . Comparisons with the Global study should be

made mindfully, considering that PA Consulting de veloped potential estimates using a high-level, topdown approach in contrast to Global’s bottom-up methodology. That said, the results and potentials

are similar. The PA savings are in the middle of Gl obal’s achievable range for the first 10 years, and

at the lower end for the second ten years.



# North Carolina’s Energy Future: Electricity, Water, and Transportation

Efficiency — ACEEE

This study was published in 2010. It presents a po rtfolio of energy efficiency, water savings, and

transportation efficiency policy options for the state of North Carolina that could potentially

reduce the state’s electricity needs by nearly a quarter and transportation fuel requirements by

more than 10% by 2025. The contractors for this study were ACEEE, Potomac Resources,

Navigant Consulting, ICF International, and Synapse Energy Economics.

Analysis approach: The analysis captures existing activi ties related to energy and water use

efficiency improvements, and models a suite of expanded energy, water, and transportation

efficiency policy options. The analysis draws on benchmarking experience from other states and

stakeholder feedback from within the state. At the core of the policy options is the Energy

Efficiency Resource Standard (EERS). Other policy options are built around EERS to help achieve

a maximum level of savings. Cost-effectiveness as sessment of the policy op tions is based on TRC

and Participant Cost Tests. In addition to pote ntial savings estimation, the study also estimates

macroeconomic impacts associated with energy efficiency investments using a macroeconomic

model. The timeframe of the study is from 2009 to 2025.

Baseline forecast: The base year for electricity sales in the state is 2008 and is grounded in

EIA’s Electric Power Annual- 2007 State Data Tables . The projections through 2025 are based on

electricity-utility filed IRPs in 2009 for the stat e. The baseline forecast incorporates federal

lighting and appliance standards enacted in 2007.TVA Energy Efficiency Potential Study, Volume 2 Comparison of Previous Potential Studies

9-12 www.gepllc.com 

## Levels of potential: The study presented results for two le vels of potential associated with

implementation of the policy packages for variou s sectors. There is a medium case scenario and

high case scenario with the same set of policy options, but different program penetration rates

and customer incentive levels.

Study Findings: Table 9-12 summarizes the key findings.

Table 9-12 Savings Potential Summary – ACEEE North Carolina

Scenario Electricity savings by

Medium case scenario 7,517 GWh (5.6%) 21,651 GWh (14.9%) 37,830 GWh (23.7%)

High case scenario 10,594 GWh (7.8%) 29,523 GWh (20.4%) 51,748 GWh (32.4%)

Comparison to Global TVA Study: Comparisons with the Global study should be made cautiously,

considering that this study developed potential es timates using a high-level, top-down approach in

contrast to Global’s bottom-up methodology. Addi tionally, the content is specifically targeted for

North Carolina, which has entirely different customer and usage characteristics. The baseline forecast

is based on EIA’s 2007 State Data Tables and data from North Caro lina utility IRPs, and includes the

effects of the EISA lighting standard. The ACEEE approach will tend to have considerably higher

potential due to the inclusion of high-level policy options such as promotion of CHP, building codes,

and electricity savings from water-saving initiatives.Global Energy Partners

# MARKET PROFILES

Market profiles describe electricity use by sector, segment, end use and technology in the base

year of the study (2009). The market profiles ar e given for average buildi ngs and new vintages.

As explained in Chapter 2, a market profile includes the following elements:

• Market size is a representation of the number of customers in the segment. For the

residential sector, it is number of households. In the commercial sector, it is floor space

measured in square feet. For the industrial sector, it is number of employees.

• Saturations define the fraction of buildings with the electric technologies. (e.g., homes

with electric space heating, commercial floor space with space cooling).

• UEC (unit energy consumption) or EUI (energy-use index) describes the amount

of electricity consumed in 2009 by a specific technology in buildings that have the

technology. We use UECs expressed in kWh/household for the residential sector, and

EUIs expressed in kWh/square foot or kW h/employee for the commercial and industrial

sectors respectively.

• Intensity for the residential sector represents the average use for the technology across

all homes in 2009. It is computed as the product of the saturation and the UEC and is

defined as kWh/household. For the commerc ial and industrial sectors, intensity,

computed as the product of the saturation and the EUI, represents the average use for

the technology across all floor space in 2009.

• Usage is the annual electricity use by a technology/end use in the segment. It is the

product of the market size and intens ity and is quantified in GWh.

This appendix presents the following residential market profiles:

• Residential market profiles by segment

• Commercial market profiles by building type

• Industrial market profilesAppendix A TVA Energy Efficiency Potential StudyA-2www.gepllc.com

## Table B-8 through Table B-13 list the detailed un it-level data for the non-equipment energy

efficiency measures for each of the housin g type segments and for existing and new

construction, respectively. Because these measures can produce energy-use savings for multiple

end-use loads (e.g., insulation affects heating an d cooling energy use) savings are expressed as

a percentage of the end-use loads. Base saturati on indicates the percentage of homes in which

the measure is already installed. Applicability/Feasibility is the product of two factors that

account for whether the measure is applicable to the building. Cost is expressed in $/household.

The detailed measure-level tables present the re sults of the benefit/cost (B/C) analysis for the

first year of the forecast although the B/C ratio is calculated within LoadMAP for each year of the

forecast. The B/C ratio is zero if the measure represents the baseline technology or if the

measure is not available in 2012.TVA Energy Efficiency Potential Study Appendix B

## Table B-1 Residential Energy-Efficiency Equipment/Measure Descriptions

End

‐ Use Equipment/ Measure Description

Cooling Central Air Conditioner

— (CAC) Central air conditioners consist of a refrigeration system using a

direct expansion cycle. Equipment includes a compressor, an air

‐

cooled condenser (located outdoors), an expansion valve, and

an evaporator coil. A supply fan near the evaporator coil

distributes supply air through air ducts to the building. Cooling

efficiencies vary based on materials used, equipment size,

condenser type, and system configuration. CACs may be unitary

(all components housed in a factory

‐ built assembly) or split

system (an outdoor condenser section and an indoor evaporator

section connected by refrigerant lines and with the compressor

either indoors or outdoors). Energy efficiency is rated according

to the size of the unit using the Seasonal Energy Efficiency

Rating (SEER). Ductless systems with Variable Refrigerant Flow

further improve the operating efficiency.

Cooling Room Air Conditioner

–

ENERGY STAR or better Room air conditioners are designed to cool a single room or

space. They incorporate a complete air

‐ cooled refrigeration and

air

‐ handling system in an individual package. Room air

conditioners come in several forms, including window, split

‐

type, and packaged terminal units. Energy efficiency is rated

according to the size of the unit using the Energy Efficiency

Rating (EER).

Cooling Central Air Conditioner

Maintenance and Tune

Up An air conditioner's filters, coils, and fins require regular

cleaning and maintenance for the unit to function effectively

and efficiently throughout its life. Neglecting necessary

maintenance leads to a steady decline in performance, requiring

the AC unit to use more energy for the same cooling load.

Cooling Attic Fan Attic fans can reduce the need for AC by reducing heat transfer

from the attic through the ceiling of the house. A well

‐ ventilated

attic can be several degrees cooler than a comparable,

unventilated attic. An option for an attic fan equipped with a

small solar photovoltaic generator is also modeled.

Cooling Ceiling Fan Ceiling fans can reduce the need for air conditioning. However,

the house occupants must also select a ceiling fan with a high

‐ efficiency motor and either shutoff the AC system or setup the

thermostat temperature of the air conditioning system to

realize the potential energy savings. Some ceiling fans also come

with lamps. In this analysis, it is assumed that there are no

lamps, and installing a ceiling fan will allow occupants to

increase the thermostat cooling setpoint up by 2°F.

Cooling Whole

‐ House Fan Whole

‐ house fans can reduce the need for AC on moderate

‐

weather days or on cool evenings. The fan facilitates a quick air

change throughout the entire house. Several windows must be

open to achieve the best results. The fan is mounted on the top

floor of the house, usually in a hallway ceiling.

Cooling Dehumidifier By reducing humidity within the home, dehumidifiers improve

comfort and allow raising the air conditioning set point. ENERGY

STAR rated units are available.Appendix B TVA Energy Efficiency Potential Study

Combined Heating /

Cooling Air Source Heat Pump A central heat pump consists of components similar to a CAC

system, but is usually designed to function both as a heat pump

and an air conditioner. It consists of a refrigeration system using

a direct expansion (DX) cycle. Equipment includes a compressor,

an air

‐ cooled condenser (located outdoors), an expansion valve,

and an evaporator coil (located in the supply air duct near the

supply fan) and a reversing valve to change the DX cycle from

cooling to heating when required. The cooling and heating

efficiencies vary based on the materials used, equipment size,

condenser type, and system configuration. Heat pumps may be

unitary (all components housed in a factory

‐ built assembly) or a

split system (an outdoor condenser section and an indoor

evaporator section connected by refrigerant lines, with either

outdoors or indoors. A high

‐ efficiency option for a ductless mini

‐ split system is also analyzed.

Combined Heating /

Cooling Geothermal Heat Pump Geothermal heat pumps are similar to air

‐ source heat pumps,

but use the ground or groundwater instead of outside air to

provide a heat source/sink. A geothermal heat pump system

generally consists of three major subsystems or parts: a

geothermal heat pump to move heat between the building and

the fluid in the earth connection, an earth connection for

transferring heat between the fluid and the earth, and a

distribution subsystem for delivering heating or cooling to the

building. The system may also have a desuperheater to

supplement the building's water heater, or a full

‐ demand water

heater to meet all of the building's hot water needs.

Combined Heating /

Cooling Central Heat Pump

Maintenance A heat pump's filters, coils, and fins require regular cleaning and

maintenance for the unit to function effectively and efficiently

throughout its life. Neglecting necessary maintenance ensures a

steady decline in performance while energy use steadily

increases.

HVAC (all) Insulation

– Ducting Air distribution ducts can be insulated to reduce heating or

cooling losses. Best results can be achieved by covering the

entire surface area with insulation. Several types of ducts and

duct insulation are available, including flexible duct, pre

‐

insulated duct, duct board, duct wrap, tacked, or glued rigid

insulation, and waterproof hard shell materials for exterior

ducts. This analysis assumes that installing duct insulation can

reduce the temperature drop/gain in ducts by 50%.

HVAC (all) Ducting, Repair and

Sealing An ideal duct system would be free of leaks. Leakage in

unsealed ducts varies considerably because of differences in

fabricating machinery used, methods for assembly, installation

workmanship, and age of the ductwork. Air leaks from the

system to the outdoors result in a direct loss proportional to the

amount of leakage and the difference in enthalpy between the

outdoor air and the conditioned air. This analysis assumes that

over time air loss from ducts has doubled, and conducting repair

and sealing of the ducts will restore leakage from ducts to the

original baseline level.TVA Energy Efficiency Potential Study Appendix B

HVAC (all) Doors

— Storm and

Thermal Like other components of the shell, doors are subject to several

types of heat loss: conduction, infiltration, and radiant losses.

Similar to a storm window, a storm door creates an insulating

air space between the storm and primary doors. A tight fitting

storm door can also help reduce air leakage or infiltration.

Thermal doors have exceptional thermal insulation properties

and also are provided with weather

‐ stripping on the doorframe

to reduce air leakage.

HVAC (all) Windows

— High

Efficiency / ENERGY

STAR High

‐ efficiency windows, such as those labeled under the

ENERGY STAR Program, are designed to reduce energy use and

increase occupant comfort. High

‐ efficiency windows reduce the

amount of heat transfer through the glazing surface. For

example, some windows have a low

‐ E coating, a thin film of

metallic oxide coating on the glass surface that allows passage

of short

‐ wave solar energy through glass and prevents long

‐

wave energy from escaping. Another example is double

‐ pane

glass that reduces conductive and convective heat transfer.

Some double

‐ pane windows are gas

further increase the insulating properties of the window.

Cooling Roof

— High Reflectivity The color and material of a building structure surface determine

the amount of solar radiation absorbed by that surface and

subsequently transferred into a building. This is called solar

absorptance. Using a roofing material with low solar

absorptance or painting the roof a light color reduces the

cooling load. This analysis assumes that implementing high

reflectivity roofs will decrease the roof’s absorptance of solar

radiation by 45%.

HVAC (all) Thermostat

— Clock/Programmable A programmable thermostat can be added to most

heating/cooling systems. They are typically used during winter

to lower temperatures at night and in summer to increase

temperatures during the afternoon. The energy savings from

this type of thermostat are identical to those of a "setback"

strategy with standard thermostats, but the convenience of a

programmable thermostat makes it a much more attractive

option. In this analysis, the baseline is assumed to have no

thermostat setback.

Water Heating Water Heater

‐ Electric,

High Efficiency (includes

Heat Pump Water

Heater) For electric hot water heating, the most common type is a

storage heater, which incorporates an electric heating element,

storage tank, outer jacket, insulation, and controls in a single

unit. Efficient units are characterized by a high recovery or

thermal efficiency and low standby losses (the ratio of heat lost

per hour to the content of the stored water). A further

efficiency gain is available through a heat pump water heater

(HPWH), which uses a vapor

‐ compression thermodynamic cycle

similar to that found in an air

‐ conditioner or refrigerator to

extract heat from an available source (e.g., air) and reject that

heat to a higher temperature sink, in this case, the water in the

water heater. Solar thermal water heating systems are also

modeled. Electric instantaneous water heaters are available, but

are excluded from this study due to potentially high

instantaneous demand concerns.

Water Heating Water Heating, Solar Solar water heating systems can be used in residential buildings

that have an appropriate near

‐ south

‐ facing roof or nearby

unshaded grounds for installing a collector. Although system

types vary, in general these systems use a solar absorber surface

within a solar collector or an actual storage tank. Either a heat

‐

transfer fluid or the actual potable water flows through tubes

attached to the absorber and transfers heat from it. (Systems

with a separate heat

‐ transfer

‐ fluid loop include a heat

exchanger that then heats the potable water.) The heated water

is stored in a separate preheat tank or a conventional water

heater tank. If additional heat is needed, it is provided by a

conventional water

‐ heating system.

Water Heating Faucet Aerators Water faucet aerators are threaded screens that attach to

existing faucets. They reduce the volume of water coming out of

faucets while introducing air into the water stream. This

measure provides energy saving by reducing hot water use, as

well as water conservation for both hot and cold water.TVA Energy Efficiency Potential Study Appendix B

Water Heating Pipe Insulation Insulating hot water pipes decreases energy losses from piping

that distributes hot water throughout the building. I also results

in quicker delivery of hot water and may allow lower the hot

water set point, which saves energy. The most common

insulation materials for this purpose are polyethylene and

neoprene.

Water Heating Low

‐ Flow Showerheads Similar to faucet aerators, low

‐ flow showerheads reduce the

consumption of hot water, which in turn decreases water

heating energy use.

Water Heating Tank Blanket Insulating hot water tanks decreases standby energy losses from

the tank. Pre

‐ fitted insulating blankets are readily available.

Water Heating Thermostat Setback /

Timer These measures use either a programmable thermostat or a

timer to adjust the water heater setpoint at times of low usage,

typically when a home is unoccupied.

Water Heating Hot Water Saver A hot water saver is a plumbing device that attaches to the

showerhead and that pauses the flow of water until the water is

hot enough for use. The water is re

‐ started by the flip of a

switch.

Water Heating Drainwater Heat

Recovery Drainwater Heat Recovery is a system in which drain water is

used to preheat cold water entering the water heater. While

these systems themselves are relatively inexpensive, upgrading

an existing system could be unreasonable because of demolition

costs. Thus they are modeled for new vintage only.

Interior Lighting /

standards incandescent lamps. Also referred to as advanced

incandescent lamps, these products meet the Energy

Lamps Compact fluorescent lamps are designed to be a replacement

for standard incandescent lamps and use about 25% of the

energy used by standard incandescent lamps to produce the

‐ Use Equipment/ Measure Description

Interior Lighting Fluorescent, T8, Super

T8, and T5 Lamps and

Electronic Ballasts T8 fluorescent lamps are smaller in diameter than standard T12

lamps, resulting in greater light output per watt. T8 lamps also

operate at a lower current and wattage, which increases the

efficiency of the ballast but requires the lamps to be compatible

with the ballast. Fluorescent lamp fixtures can include a

reflector that increases the light output from the fixture, and

thus make it possible to use a fewer number of lamps in each

fixture. T5 lamps further increase efficiency by reducing the

lamp diameter to 5/8”.

Interior Lighting Occupancy Sensors Occupancy sensors turn lights off when a space is unoccupied.

They are appropriate for areas with intermittent use, such as

bathrooms or storage areas.

Exterior Lighting Photovoltaic Installation Solar photovoltaic generation may be used to power exterior

lighting and thus eliminate all or part of the electrical energy

use.

Exterior Lighting Photosensor Control Photosensor controls turn exterior lighting on or off based on

ambient lighting levels. Compared with manual operation, this

can reduce the operation of exterior lighting during daylight

hours.

Exterior Lighting Timeclock Installation Lighting timers turn exterior lighting on or off based on a preset

Cooling Chiller

High

‐ efficiency A central chiller plant creates chilled water for distribution

throughout the facility. Because of the wide variety of system types

and sizes, savings and cost values for efficiency improvements

represent an average over screw, reciprocating, and centrifugal

technologies. Under this simplified approach, each central system is

characterized by an aggregate efficiency value (inclusive of chiller,

pumps, and motors), in kW/ton with a further efficiency upgrade

through the application of variable refrigerant flow technology.

Cooling Chiller

via a condenser loop and cooling tower. Because of the wide variety

improvements represent an average over screw, reciprocating, and

centrifugal technologies. Under this simplified approach, each

central system is characterized by an aggregate efficiency value

in kW/ton with a further efficiency upgrade through the application

of variable refrigerant flow technology.

Cooling Air Conditioner

‐ Packaged, High

‐ efficiency (including

ductless mini

‐ split) Packaged cooling systems, such as rooftop units (RTUs), are simple

to install and maintain, and are commonly used in small and

medium

‐ sized commercial buildings. Applications range from a

single supply system with air intake filters, supply fan, and cooling

coil, or can become more complex with the addition of a return air

duct, return air fan, and various controls to optimize performance.

For packaged RTUs, varying Energy Efficiency Ratios (EER) are

modeled, as well as a ductless mini

‐ split system.

Cooling Cooling Other, High

Efficiency This measure includes efficiency upgrades to other small cooling

systems in commercial buildings including room AC units, packaged

terminal air conditioning (PTAC) units, and packaged terminal heat

pumps (PTHP).

‐ efficiency (including

ductless mini

evaluated, as well as a ductless mini

Cooling Chiller, Variable

Speed Drive Variable speed drives, which reduce chiller energy use under part

load, are modeled for both air

‐ cooled and water

‐ cooled chillers.

Cooling Chiller, Condenser

Water Temperature

Reset Chilled water reset controls save energy by improving chiller

performance through increasing the supply chilled water

temperature, which allows increased suction pressure during low

load periods. Raising the chilled water temperature also reduces

chilled water piping losses. However, the primary savings from the

chilled water reset measure results from chiller efficiency

improvement. This is due partly to the smaller temperature

difference between chilled water and ambient air, and partly due to

the sensitivity of chiller performance to suction temperature.

Cooling Air

High

‐ Efficiency Fans For air

frequency drives that improve fan performance by adjusting fan

speed and rotation as conditions change.TVA Energy Efficiency Potential Study Appendix C

Cooling Water

Cooling Tower, High

‐ cooled chillers, high

variable frequency drives in the cooling tower design. VFDs improve

fan performance by adjusting fan speed and rotation as conditions

change.

Cooling Water

‐ cooled Chiller,

Condenser Water

Temperature Reset Resetting the condenser water temperature to the lowest possible

setting allows the cooling tower to generate cooler water whenever

possible and decreases the temperature lift between the condenser

and the evaporator. This will generally increase chiller part

‐ load

efficiency, though it may require increased tower fan energy use.

Cooling Chiller, Economizer,

Installation Economizers allow outside air (when it is cool and dry enough) to be

brought into the building space to meet cooling loads instead of

using mechanically cooled interior air. A dual enthalpy economizer

consists of indoor and outdoor temperature and humidity sensors,

dampers, motors, and motor controls. Economizers are most

applicable to temperate climates and savings will be smaller in

extremely hot or humid areas.

Cooling Chiller, Thermal

Energy Storage This measure uses energy at off

‐ peak times to create a chilled

media, typically cool water or ice, then stores it in an insulated

chamber until peak hours. During peak hours, it uses the cooling

energy stored in the media by running the chiller loop through a

heat exchanger in the thermal storage chamber, thereby reducing

energy and peak demand from the grid.

Combined

Heating /

Cooling Heat Pump,

Maintenance Regular cleaning and maintenance enables a heat pump to function

effectively and efficiently throughout its years of service. Neglecting

necessary maintenance leads to a steady decline in performance

while energy use increases. Maintenance can increase the efficiency

of poorly performing equipment by as much as 10%.

Cooling RTU, Maintenance Regular cleaning and maintenance enables a roof top unit to

function effectively and efficiently throughout its years of service.

Neglecting necessary maintenance leads to a steady decline in

performance while energy use increases. Maintenance can increase

the efficiency of poorly performing equipment by as much as 10%.

Ventilation Variable Air

‐ Volume

Systems A variable air volume ventilation system modulates the air flow rate

as needed based on the interior conditions of the building to reduce

fan load, improve dehumidification, and reduce energy usage.

Ventilation Ventilation

‐ Variable

Speed Control Variable speed controls adjust ventilation fans for part

‐ load

conditions to reduce energy use. This can be accomplished by using

electronically commutated motors (ECM's).

Ventilation Ventilation

‐ CO2

Controlled Carbon dioxide (CO2) levels indicate the level of occupancy in a

space. This measure uses sensors to monitor CO2 levels and controls

on the air handling system to adjust the amount of outside air

accordingly. Ventilation rates are thereby controlled based on

occupancy, rather than a fixed rate, thus saving HVAC energy use.

Ventilation Ventilation

‐ Exhaust

Hood Sensor Control Improved exhaust hoods involve installing variable

‐ speed controls

on commercial kitchen hoods. These controls provide ventilation

based on actual cooking loads. When grills, broilers, stoves, fryers or

other kitchen appliances are not being used, the controls

automatically sense the reduced load and decrease the fan speed

accordingly. This results in lower energy consumption because the

system is only running as needed rather than at 100% capacity at all

times.Appendix C TVA Energy Efficiency Potential Study

Ventilation Fans, Energy

Motors High

‐ efficiency motors are essentially interchangeable with standard

motors, but differences in construction make them more efficient.

to mechanical energy. This analysis assumes that the efficiency of

supply fans is increased by 5% due to installing energy

‐ efficient

motors.

HVAC Pumps, Variable

Speed Control The part

‐ load efficiency of chilled water / hot water loop pumps can

be improved substantially by varying the speed of the motor drive

according to the building demand for heating or cooling. This

measure also reduces piping losses. However, pump speeds can

generally only be reduced to a minimum specified rate, because

chillers, boilers, and control valves may require a minimum flow rate

to operate. Two major types of variable speed drives are mechanical

and electronic. An additional benefit of variable

‐ speed drives is the

ability to start and stop the motor gradually, thus extending the life

of the motor and associated machinery. This analysis assumes that

electronic variable speed drives are installed.

HVAC Ducting, Insulation Air distribution ducts can be insulated to reduce heating or cooling

losses. Best results can be achieved by covering the entire surface

area with insulation. Insulation material inhibits the transfer of heat

through the air

‐ supply duct. Several types of ducts and duct

insulation are available, including flexible duct, pre

‐ insulated duct,

duct board, duct wrap, tacked, or glued rigid insulation, and

waterproof hard shell materials for exterior ducts.

HVAC Ducting, Repair and

Sealing Leakage in unsealed ducts varies considerably because of the

differences in fabricating machinery used, the methods for

assembly, installation workmanship, and age of the ductwork. Air

leaks from the system to the outdoors result in a direct loss

proportional to the amount of leakage and the difference in

enthalpy between the outdoor air and the conditioned air. To seal

ducts, a wide variety of sealing methods and products exist. Each

has a relatively short shelf life, and no documented research has

identified the aging characteristics of sealant applications. This

analysis assumes that the baseline air loss from ducts has doubled,

and conducting repair and sealing of the ducts will restore leakage

from ducts to the original baseline level.

HVAC Insulation, Ceiling Thermal insulation is material or combinations of materials that are

used to inhibit the flow of heat energy by conductive, convective,

and radiative transfer modes. Thus, thermal insulation can conserve

energy by reducing the heat loss or gain of a building. The type of

building construction defines insulating possibilities. Typical

insulating materials include: loose

‐ fill (blown) cellulose; loose

‐ fill

(blown) fiberglass; and rigid polystyrene.TVA Energy Efficiency Potential Study Appendix C

Cavity Thermal insulation is material or combinations of materials that are

used to inhibit the flow of heat energy by conductive, convective,

and radiative transfer modes. Thus, thermal insulation can conserve

energy by reducing the heat loss or gain of a building. The type of

building construction defines insulating possibilities. Typical

insulating materials include: loose

‐ fill (blown) cellulose; loose

‐ fill

(blown) fiberglass; and rigid polystyrene.

HVAC Roofs, Cool Roof The color and material of a building structure surface will determine

the amount of solar radiation absorbed by that surface and

subsequently transferred into a building. This is called solar

absorptance. By using a living roof or a roofing material with a light

color (and a lower solar absorptance), the roof will absorb less solar

radiation and consequently reduce the cooling load. Living roofs also

reduce stormwater runoff.

HVAC Windows, High

Efficiency High

‐ efficiency windows, such as those labeled under the ENERGY

STAR Program, are designed to reduce a building's energy bill while

increasing comfort for the occupants at the same time. High

‐ efficiency windows have reducing properties that reduce the

amount of heat transfer through the glazing surface. For example,

some windows have a low

‐ E coating, which is a thin film of metallic

oxide coating on the glass surface that allows passage of short

‐ wave

solar energy through glass and prevents long

‐ wave energy from

escaping. Another example is double

‐ pane glass that reduces

conductive and convective heat transfer. There are also double

‐

pane glasses that are gas

‐ filled (usually argon) to further increase

the insulating properties of the window.

HVAC,

Lighting Energy Management

System An energy management system (EMS) allows managers/owners to

monitor and control the major energy

‐ consuming systems within a

commercial building. At the minimum, the EMS can be used to

monitor and record energy consumption of the different end

‐ uses in

a building, and can control operation schedules of the HVAC and

lighting systems. The monitoring function helps building

managers/owners to identify systems that are operating inefficiently

so that actions can be taken to correct the problem. The EMS can

also provide preventive maintenance scheduling that will reduce the

cost of operations and maintenance in the long run. The control

functionality of the EMS allows the building manager/owner to

operate building systems from one central location. The operation

schedules set via the EMS help to prevent building systems from

operating during unwanted or unoccupied periods. This analysis

assumes that this measure is limited to buildings with a central

HVAC system.

HVAC Thermostat,

Clock/Programmable A programmable thermostat can be added to most heating/cooling

systems. They are typically used during winter to lower

temperatures at night and in summer to increase temperatures

during the afternoon. There are two

‐ setting models, and well as

models that allow separate programming for each day of the week.

The energy savings from this type of thermostat are identical to

those of a "setback" strategy with standard thermostats, but the

convenience of a programmable thermostat makes it a much more

attractive option. In this analysis, the baseline is assumed to have

no thermostat setback.Appendix C TVA Energy Efficiency Potential Study

Interior

Lighting LED Exit Lighting The lamps inside exit signs represent a significant energy end

‐ use,

since they usually operate 24 hours per day. Many old exit signs use

incandescent lamps, which consume approximately 40 watts per

sign. The incandescent lamps can be replaced with LED lamps that

are specially designed for this specific purpose. In comparison, the

LED lamps consume approximately 2

‐ 5 watts.

Interior

Lighting Occupancy Sensors The installation of occupancy sensors allows lights to be turned off

during periods when a space is unoccupied, virtually eliminating the

wasted energy due to lights being left on. There are several types of

occupancy sensors in the market.

Interior

Lighting Task Lighting Individual work areas can use task lighting instead of brightly lighting

the entire area. Significant energy savings can be realized by

focusing light directly where it is needed and lowering the general

lighting level. An example of task lighting is the common desk lamp.

A 25W desk lamp can be installed in place of a typical lamp in a

fixture.

Interior

Lighting Time Clocks and

often performed as a separate energy efficiency measure in which a

lighting engineer analyzes the lighting provided by current systems

compared to the requirements of building occupants. This often

leads to the removal of unnecessary lamps corresponding to an

overall reduction in energy usage. .In addition, installing a reflector

in each fixture can improve light distribution from the remaining

lamps.TVA Energy Efficiency Potential Study Appendix C

Electric, High

‐ Efficiency and Heat

Pump Water Heaters Efficient electric water heaters are characterized by a high recovery

or thermal efficiency (percentage of delivered electric energy which

is transferred to the water) and low standby losses (the ratio of heat

lost per hour to the content of the stored water). Included in the

savings associated with high

‐ efficiency electric water heaters are

timers that allow temperature setpoints to change with hot water

demand patterns. For example, the heating element could be shut

off throughout the night, increasing the overall energy factor of the

unit. In addition, tank and pipe insulation reduces standby losses and

therefore reduces the demands on the water heater. This analysis

considers conventional electric water heaters and heat pump water

heaters.

Water

Heating Faucet Aerators and

Low Flow Nozzles A faucet aerator or low flow nozzle spreads the stream from a faucet

helping to reduce water usage. The amount of water passing

through the aerator is measured in gallons per minute (GPM) and

the lower the GPM the more water the aerator conserves.

Water

Heating Pipe

‐ Hot Water,

Insulation Insulating hot water pipes decreases the amount of energy lost

during distribution of hot water throughout the building. Insulating

pipes will result in quicker delivery of hot water and allows lowering

the water heating set point. There are several different types of

insulation, the most common being polyethylene and neoprene.

Water

Heating Water Heating, Tank

Blanket Insulation levels on hot water heaters can be increased by installing

a fiberglass blanket on the outside of the tank. This increase in

insulation reduces standby losses and thus saves energy. Water

of fiberglass insulation with R

Heating Water Heating, Solar

Water Heating

System Solar water heating systems can be used in commercial buildings

that have an appropriate flat or near

‐ south

‐ facing roof or nearby

unshaded grounds for installing a collector. Although system types

vary, in general these systems use a solar absorber surface within a

solar collector or an actual storage tank. Either a heat

‐ transfer fluid

or the actual potable water flows through tubes attached to the

absorber and transfers heat from it. (Systems with a separate heat

‐

transfer

‐ fluid loop include a heat exchanger that then heats the

potable water.) The heated water is stored in a separate preheat

tank or a conventional water heater tank. If additional heat is

needed, it is provided by a conventional water

‐ heating system.

Water

Heating Water Heating, Heat

Trap Heat traps are valves that only allow water to flow one way in a

pipe. They typically operate by means of a ball that sinks or floats

depending on flow conditions to open and close the tap. They are

‐ temperature display

cases and many medium

‐ temperature cases to control humidity and

prevent the condensation of water vapor on the sides and doors and

on the products contained in the cases. Typically, these heaters stay

on all the time, even though they only need to be on about half the

time. Anti

‐ sweat heater controls can come in the form of humidity

sensors or time clocks.

Refrigeration Door Gasket,

Refrigeration Vending Machine,

High Efficiency High

‐ efficiency vending machines incorporate more efficient

compressors and lighting.

Refrigeration Vending Machine,

Controller Cold beverage vending machines usually operate 24 hours a day

regardless of whether the surrounding area is occupied or not. The

result is that the vending machine consumes energy unnecessarily,

because it will operate all night to keep the beverage cold even

when there would be no customers until the next morning. A

vending machine controller can reduce energy consumption without

compromising the temperature of the vended product. The

controller uses an infrared sensor to monitor the surrounding area's

occupancy and will power down the vending machine when the area

is unoccupied. It will also monitor the room's temperature and will

re

‐ power the machine at one to three hour intervals independent of

occupancy to ensure that the product stays cold.

Food Prep Cooking Equipment,

‐ Copier/Printer,

ENERGY STAR ENERGY STAR labeled office equipment saves energy by powering

down and "going to sleep" when not in use. ENERGY STAR labeled

copiers are equipped with a feature that allows them to

automatically turn off after a period of inactivity, reducing a copier's

annual electricity costs by over 60%. High

‐ speed copiers that

include a duplexing unit that is set to automatically make double

‐

sided copies can reduce paper costs and help to save trees.

ENERGY STAR Power supplies with an efficient ac

‐ dc or ac

‐ ac conversion process

can obtain the ENERGY STAR label. These devices can be used to

power computers, phones, and other office equipment.

HVAC,

Interior

Lighting Hotel Guestroom

Controls (occupancy) Hotel guestrooms can be fitted with occupancy controls that turn off

energy

‐ using equipment when the guest is not using the room. The

occupancy controls comes in several forms, but this analysis

assumes the simplest kind, which is a simple switch near the room’s

entry where the guest can deposit their room key or card. If the key

or card is present, then lights, TV, and air conditioning can receive

power and operate. When the guest leaves and takes the key, all

equipment shuts off.

Miscellaneous Non

‐ HVAC Motors Includes motors for a variety of non

‐ HVAC uses including vertical

transportation. Premium efficiency motors can provide savings of

0.5% to 3% over standard motors. The savings results from the fact

that energy efficient motors run cooler than their standard

counterparts, resulting in an increase in the life of the motor

insulation and bearing. In general, an efficient motor is a more

reliable motor because there are fewer winding failures, longer

periods between needed maintenance, and fewer forced outages.

For example, using copper instead of aluminum in the windings, and

increasing conductor cross

‐ sectional area, lowers a motor’s I2R

losses.

Miscellaneous Non

‐ HVAC Motors,

Variable Speed

Control The part

‐ load efficiency of motor can be improved by varying the

speed of the motor drive. There are two major types of variable

speed controls: mechanical and electronic. An additional benefit of

variable

‐ speed controls is the ability to start and stop the motor

gradually, thus extending the life of the motor and associated

machinery. This analysis assumes that electronic variable speed

controls are installed.

Miscellaneous Pool, Efficient Pool

Pumps High

‐ efficiency motors and two

‐ speed pumps provide improved

energy efficiency for this load.

Miscellaneous Pool, Heat Pump or

Solar Heating System This measure replaces an electric resistance pool heater with a heat

pump or solar system.

Miscellaneous Pool, Pump Timer A pool pump timer allows the pump to turn off automatically,

eliminating the wasted energy associated with unnecessary

pumping.TVA Energy Efficiency Potential Study Appendix C

## Table D-1 Industrial Energy-Efficiency Equipment/Measure Descriptions

End Use Equipment/ Measure Industrial Measure Description

Cooling Roof Top AC Rooftop cooling systems, such as rooftop units (RTUs), are simple to

install and maintain. Applications range from a single supply system

with air intake filters, supply fan, and cooling coil, or can become

more complex with the addition of a return air duct, return air fan,

and various controls to optimize performance. Varying Energy

Efficiency Ratios (EER) are modeled.

Cooling Cooling Other, High

Efficiency This measure includes efficiency upgrades to other cooling systems

in industrial buildings.

Combined

Heating/Cooling Roof Top Heat Pump For heat pumps, units with increasing EER and COP levels are

evaluated, as well as a ductless mini

‐ split system and a geothermal

system.

Cooling Chiller, Variable Speed

Drive Variable speed drives, which reduce chiller energy use under part

load, are modeled for both air

‐ cooled and water

‐ cooled chillers.

Cooling Chiller, Condenser

Water Temperature

Reset Chilled water reset controls save energy by improving chiller

performance through increasing the supply chilled water

temperature, which allows increased suction pressure during low

load periods. Raising the chilled water temperature also reduces

chilled water piping losses. However, the primary savings from the

chilled water reset measure results from chiller efficiency

improvement. This is due partly to the smaller temperature

difference between chilled water and ambient air, and partly due to

the sensitivity of chiller performance to suction temperature.

Cooling Air

‐ cooled Chiller,

High

‐ Efficiency Fans For air

‐ cooled chillers, high

‐ efficiency cooling fans utilize variable

frequency drives that improve fan performance by adjusting fan

speed and rotation as conditions change.

Cooling Water

Cooling Tower, High

‐ Efficiency Fans For water

‐ cooled chillers, high

‐ efficiency cooling tower fans utilize

variable frequency drives in the cooling tower design. VFDs improve

fan performance by adjusting fan speed and rotation as conditions

change.

Cooling Water

‐ cooled Chiller,

Condenser Water

Temperature Reset Resetting the condenser water temperature to the lowest possible

setting allows the cooling tower to generate cooler water whenever

possible and decreases the temperature lift between the condenser

and the evaporator. This will generally increase chiller part

‐ load

efficiency, though it may require increased tower fan energy use.

Cooling Chiller, Economizer,

Installation Economizers allow outside air (when it is cool and dry enough) to be

brought into the building space to meet cooling loads instead of

using mechanically cooled interior air. A dual enthalpy economizer

consists of indoor and outdoor temperature and humidity sensors,

dampers, motors, and motor controls. Economizers are most

applicable to temperate climates and savings will be smaller in

extremely hot or humid areas.

Cooling,

Combined

Heating/Cooling Equip Maintenance

(RTU, Heat Pump,

Chiller) Regular cleaning and maintenance enables a heat pump to function

effectively and efficiently throughout its years of service. Neglecting

necessary maintenance leads to a steady decline in performance

while energy use increases. Maintenance can increase the

efficiency of poorly performing equipment by as much as 10%.

Ventilation Variable Air

‐ Volume

Systems A variable air volume ventilation system modulates the air flow rate

as needed based on the interior conditions of the building to reduce

fan load, improve dehumidification, and reduce energy usage.TVA Energy Efficiency Potential Study Appendix D

## End Use Equipment/ Measure Industrial Measure Description

Ventilation Ventilation

‐ Variable

Speed Control Variable speed controls adjust ventilation fans for part

‐ load

conditions to reduce energy use. This can be accomplished by using

electronically commutated motors (ECM's).

Ventilation Ventilation

‐ CO2

Controlled Carbon dioxide (CO2) levels indicate the level of occupancy in a

space. This measure uses sensors to monitor CO2 levels and

controls on the air handling system to adjust the amount of outside

air accordingly. Ventilation rates are thereby controlled based on

occupancy, rather than a fixed rate, thus saving HVAC energy use.

HVAC Ducting, Insulation Air distribution ducts can be insulated to reduce heating or cooling

losses. Best results can be achieved by covering the entire surface

area with insulation. Insulation material inhibits the transfer of

heat through the air

‐ supply duct. Several types of ducts and duct

insulation are available, including flexible duct, pre

‐ insulated duct,

duct board, duct wrap, tacked, or glued rigid insulation, and

waterproof hard shell materials for exterior ducts.

HVAC Ducting, Repair and

Sealing Leakage in unsealed ducts varies considerably because of the

differences in fabricating machinery used, the methods for

assembly, installation workmanship, and age of the ductwork. Air

leaks from the system to the outdoors result in a direct loss

proportional to the amount of leakage and the difference in

enthalpy between the outdoor air and the conditioned air. To seal

ducts, a wide variety of sealing methods and products exist. Each

has a relatively short shelf life, and no documented research has

identified the aging characteristics of sealant applications. This

analysis assumes that the baseline air loss from ducts has doubled,

and conducting repair and sealing of the ducts will restore leakage

from ducts to the original baseline level.

HVAC Insulation, Ceiling Thermal insulation is material or combinations of materials that are

used to inhibit the flow of heat energy by conductive, convective,

and radiative transfer modes. Thus, thermal insulation can

conserve energy by reducing the heat loss or gain of a building. The

type of building construction defines insulating possibilities. Typical

insulating materials include: loose

‐ fill (blown) cellulose; loose

‐ fill

(blown) fiberglass; and rigid polystyrene.

HVAC Insulation, Wall Cavity Thermal insulation is material or combinations of materials that are

used to inhibit the flow of heat energy by conductive, convective,

and radiative transfer modes. Thus, thermal insulation can

conserve energy by reducing the heat loss or gain of a building. The

type of building construction defines insulating possibilities. Typical

insulating materials include: loose

‐ fill (blown) cellulose; loose

‐ fill

(blown) fiberglass; and rigid polystyrene.

HVAC Roofs, Cool Roof The color and material of a building structure surface will determine

the amount of solar radiation absorbed by that surface and

subsequently transferred into a building. This is called solar

absorptance. By using a living roof or a roofing material with a light

color (and a lower solar absorptance), the roof will absorb less solar

radiation and consequently reduce the cooling load. Living roofs

also reduce stormwater runoff.Appendix D TVA Energy Efficiency Potential Study

## End Use Equipment/ Measure Industrial Measure Description

HVAC, Lighting Energy Management

System An energy management system (EMS) allows managers/owners to

monitor and control the major energy

‐ consuming systems within a

building. At the minimum, the EMS can be used to monitor and

record energy consumption of the different end

‐ uses in a building,

and can control operation schedules of the HVAC and lighting

systems. The monitoring function helps building managers/owners

to identify systems that are operating inefficiently so that actions

can be taken to correct the problem. The EMS can also provide

preventive maintenance scheduling that will reduce the cost of

operations and maintenance in the long run. The control

functionality of the EMS allows the building manager/owner to

operate building systems from one central location. The operation

schedules set via the EMS help to prevent building systems from

operating during unwanted or unoccupied periods. This analysis

assumes that this measure is limited to buildings with a central

HVAC system.

HVAC Thermostat,

Clock/Programmable A programmable thermostat can be added to most heating/cooling

systems. They are typically used during winter to lower

temperatures at night and in summer to increase temperatures

during the afternoon. There are two

‐ setting models, and well as

models that allow separate programming for each day of the week.

The energy savings from this type of thermostat are identical to

those of a "setback" strategy with standard thermostats, but the

convenience of a programmable thermostat makes it a much more

attractive option. In this analysis, the baseline is assumed to have

no thermostat setback.

Interior Lighting Screw

‐ in: Halogen,

CFL, Cold Cathode,

LED This measure evaluates higher

‐ efficiency alternatives for screw

‐ in

interior lamps including halogen, CFL, Cold Cathode, and LED.

Interior Lighting High

‐ Bay Fixtures With the exception of screw

‐ in lighting, industrial lighting efficiency

changes typically require more than the simple purchase and

installation of an alternative lamp. Restrictions regarding ballasts,

fixtures, and circuitry limit the potential for direct substitution of

one lamp type for another. Also, during the buildout for a leased

office space, management could decide to replace all lamps,

ballasts, and fixtures with different configurations. This type of

decision

‐ making is modeled on a stock turnover basis because of

the time between opportunities for upgrades. For High

‐ Bay fixtures,

alternatives include mercury vapor, metal halides, T5 fluorescent

high output, and high

‐ pressure sodium.

Interior Lighting Linear Fluorescent With the exception of screw

‐ in lighting, industrial lighting efficiency

changes typically require more than the simple purchase and

installation of an alternative lamp. Restrictions regarding ballasts,

fixtures, and circuitry limit the potential for direct substitution of

one lamp type for another. Also, during the buildout for a leased

office space, management could decide to replace all lamps,

ballasts, and fixtures with different configurations. This type of

decision

‐ making is modeled on a stock turnover basis because of

the time between opportunities for upgrades. For linear fluorescent

fixtures, alternatives include T12, T8, Super T8, T5, and LED.TVA Energy Efficiency Potential Study Appendix D

## End Use Equipment/ Measure Industrial Measure Description

Interior Lighting LED Exit Lighting The lamps inside exit signs represent a significant energy end

‐ use,

since they usually operate 24 hours per day. Many old exit signs

use incandescent lamps, which consume approximately 40 watts

that are specially designed for this specific purpose. In comparison,

the LED lamps consume approximately 2

‐ 5 watts.

Interior Lighting Occupancy Sensors The installation of occupancy sensors allows lights to be turned off

during periods when a space is unoccupied, virtually eliminating the

wasted energy due to lights being left on. There are several types of

occupancy sensors in the market.

Interior Lighting Task Lighting Individual work areas can use task lighting instead of brightly

lighting the entire area. Significant energy savings can be realized

by focusing light directly where it is needed and lowering the

general lighting level. An example of task lighting is the common

desk lamp. A 25W desk lamp can be installed in place of a typical

lamp in a fixture.

Interior Lighting Time Clocks and

Timers (lighting) In many cases lighting remains on at night and during weekends. A

simple timer can set a schedule for turning lights off to reduce

operating hours.

Interior Lighting Fluorescent, Delamp

and Install Reflectors While sometimes included in lighting retrofit projects, delamping is

often performed as a separate energy efficiency measure in which a

lighting engineer analyzes the lighting provided by current systems

compared to the requirements of building occupants. This often

leads to the removal of unnecessary lamps corresponding to an

overall reduction in energy usage. .In addition, installing a reflector

in each fixture can improve light distribution from the remaining

lamps.

Motors Motors, Premium

Efficiency Premium efficiency motors reduce the amount of lost energy going

into heat rather than power. Since less heat is generated, less

energy is needed to cool the motor with a fan. Therefore, the initial

cost of energy efficient motors is generally higher than for standard

motors. However their life

‐ cycle costs can make them far more

economical because of savings they generate in operating expense.

Premium efficiency motors can provide savings of 0.5% to 3% over

standard motors. The savings results from the fact that energy

efficient motors run cooler than their standard counterparts,

resulting in an increase in the life of the motor insulation and

bearing. In general, an efficient motor is a more reliable motor

because there are fewer winding failures, longer periods between

needed maintenance, and fewer forced outages. For example,

using copper instead of aluminum in the windings, and increasing

conductor cross

‐ sectional area, lowers a motor’s I2R losses.

This analysis assumes 75% loading factor (for peak efficiency) for

1800 rpm motor. Hours of operation vary depending on

horsepower size. In addition, improved drives and controls are

assumed to be implemented along with the motors, resulting in

savings as high as 10% of annual energy consumption

Motors Motors, Efficient

Rewind When a motor burns out or is in need of repair, the owner may

elect to either replace the motor or have it rewound. A typical

motor rewind costs less than a replacement motor, but at the cost

of efficiency. An efficient rewind, however, attempts to improve the

efficiency of the motor by reducing stator losses. If the

manufacturer has left stator slots open, or not entirely filled,

additional copper wire can be included to reduce resistance and

increase efficiency. 2



## Motors Motors, Variable

Speed Control The part

‐ load efficiency of motor can be improved by varying the

speed of the motor drive. There are two major types of variable

speed controls: mechanical and electronic. An additional benefit of

variable

‐ speed controls is the ability to start and stop the motor

gradually, thus extending the life of the motor and associated

machinery. This analysis assumes that electronic variable speed

controls are installed.

Motors Integrated Plant

Energy Management This measure is based on the combination of best practices

equipment improvements and a comprehensive plant management

program including development and implementation of an energy

management plan (policy, accountabilities, goals,

department/system level targets and measurements, etc.) to

support sustainable improvement of energy intensity and

productivity, and independent verification of energy savings. The

American National Standard for energy management, or equivalent

standards, provides a point of reference for the level of

management activity assumed by this measure bundle. This

measure bundle could entail plant modernization in order to

approximate the performance of higher performing plants currently

competing in the international markets. In addition, the

management practices increase the likelihood of best practices

‐

based plant upgrades and the persistence of these savings over

time. Therefore, the savings are derived from the effective

application and operation of the high efficiency technologies, and

this is enabled by the management practices.

Motors Plant Energy

Management Includes low/no cost energy efficiency projects for multiple systems

that are supported with comprehensive demand

and good preventative maintenance practices. Maintenance and

operations are based on system

by system operator training as noted in the system optimization

measure descriptions. This measure also includes low/no cost

equipment upgrades for some of the systems.

Motors Energy Project

Management This measure is based on a package of optimized equipment

improvements, but also includes the assignment of an energy

engineer (or equivalent capability), tracking energy costs,

identification and prioritization of capital projects, application of

systems optimization tools and practices on the key systems in the

facility. Energy waste is readily identified and mitigated by the

energy engineer and his/her team, and the equipment installed

under this measure is optimized. From a program perspective, the

energy engineer function could be accomplished through other

approaches including external support.

Motors Synchronous Belts Synchronous (also known as timing, positive drive, or high

‐ torque)

belts reduce slippage through the use of toothed

‐ drive sprockets

rather than relying solely on friction. At high torque loads, slippage

can be reduced by 3%

‐ 5%. The belts require less maintenance and

retensioning and are ideal for wet/oily environments. However,

they are noisy and are unsuitable for shock loads.

Motors Transformers

‐ New &

Retrofit All electric power passes through one or more transformers on its

way to service equipment, lighting, and other loads. Currently

available materials and designs can considerably reduce both load

and no

‐ load losses. The new NEMA TP

‐ 1 standard is used as the

reference definition for energy ‐ efficient products. Tier

‐ 1 represents

TP

‐ 1 dry

‐ type transformers while Tier

‐ 2 reflects a switch to liquid

immersed TP

‐ 1 products. More efficient transformers with

attractive payback periods are estimated to save 40 to 50 percent

of the energy lost by a "typical" transformer, which translates into a

one to three percent reduction in electric bills for commercial and

industrial customers.Appendix D TVA Energy Efficiency Potential Study

industry. These fans could be replaced with more efficient

centrifugal backwardly inclined fans that increase overall fan

efficiency by 20% to 30%. The savings potential for premium

Handling Large conveyors often use gear boxes to isolate the motor and to

provide better torque control. Most current gear boxes consist of

transmissions with 90% to 92% efficiencies. Opportunities include

using higher

‐ efficiency drives, couplings, and gear/speed reducer

alternatives. In older conveyor systems, or where process

requirements have changed, it may be possible to resize a

conveyor, upgrade the controls or re

‐ engineer the system to

improve layout and configuration, all of which will result in energy

savings.

On new conveyor installations, incorporating programmable logic

controls (PLC) into the system will result in energy savings. PLC

controls regulate conveyors based on load and shut down unloaded

conveyors. Barriers to implementation include additional

maintenance costs due to the increased number of components in

the system.

Downhill conveyors employ a braking system. Energy savings can be

obtained by using a regenerative breaking system that utilizes the

momentum of the belt, the material being conveyed and the pull of

gravity converting the downhill force into electrical energy.

Additional energy savings can be gained by installing product

sensors to shut down unloaded conveyors. Barriers to system

implementation include the additional cost of a motor/generator

set and increased maintenance due to additional components in the

system.

# MARKET AND PROGRAM ACCEPTANCE FACTORS

To calculate achievable potential, we apply a set of market acceptance rates and program

implementation factors to economic potential. These parameters are described below, followed

by a discussion of how they are applied to calculate achievable potential. Finally, we present the

three sets of factors at the end of this section.

Market Acceptance Rates

The market acceptance rates (MARs) embody cu stomer awareness and willingness to adopt

energy-efficiency equipment and measures in light of perfect information about the technologies

and measures and perfect implementation of programs by utilities. Stated differently the only

barrier to customer adoption capt ured by the MARs is the custom ers’ own preferences. The MARs

increase over time, reflecting an increasing awareness and willingness to adopt energy-efficient

measures.

The MARs are applied directly to economic potentia l to calculate the Achievable – High estimates.

Program Implementation Factors

Program implementation fa ctors (PIFs) take into account existing market, financial, political, and

regulatory barriers that are likely to limit the amount of savings that might be achieved through

energy efficiency programs. For example, it considers more realistic incentives, defined

marketing campaigns, and internal budget constraints. Political barriers often reflect differences

in regional attitudes toward energy efficiency an d its value as a resource. PIFs also take into

account recent utility experience and reported saving s as well as interviews with local, state and

federal agencies, local energy efficiency cont ractors and consultants, and other interested

parties. PIF values increase over time.

PIFs are applied directly to th e Achievable – High estimates to calculate the Achievable – Low

estimates. Stated differently, the MARs and PIFs are both app lied to economic potential to

calculate the Achievable – Low estimates.

Estimates of Achievable Potential

Table E-1 and Table E-3 present the MARs that re present how Economic potential is changed to

reach Achievable – High potential for residentia l measures. Table E-2 and Table E-4 present the

product of MARs and PIFs (MAR x PIF) to show how Economic potential is changed to reach

Achievable – Low potential for residential equi pment and measures. Table E-5 through Table E-8

present MARs and MARs x PIFs for commercia l equipment and measures. Table E-9 through

Table E-12 present the same for in dustrial equipment and measures.Appendix ETVA Energy Efficiency Potential StudyE-2www.gepllc.com

## CHAPTER 1



# INTRODUCTION

Background

The Tennessee Valley Authority (TVA) has contracted with Global Energy Partners (Global) to

conduct a potential study to assess 20-year pote ntials for energy efficiency (EE) and demand

response (DR). TVA has an aspirational goal to lead the southeast in energy efficiency, and

believes this leadership can be accomplished through the development and implementation of

action plans for EE, DR, and end-use generation. Th is potential study will provide information to

assist TVA in meeting that goal.

Toward this end, Global conducted a detaile d, bottom-up assessment of the TVA market to

deliver forecasts of energy use and peak demand, as well as forecasts of energy and peakdemand savings achievable through energy ef ficiency and demand response programs. The 20-

year potentials study addresses the residential, small commercial, large commercial, and

industrial sectors. Results of this task are di scussed in two volumes, one for energy efficiency

and one for demand response, as described below in the report organization.

Global also compared the results of the potential savings to those from existing regional potential

studies that are specific to the Southeast and other select studies. This analysis, which appears

in both the energy efficiency and demand resp onse reports, also compares these potential

studies with regard to methodology, assumpti ons, approaches, estimated baselines, technical

performance, adoption, and pr ogram/regulatory context.



# Objectives

Key objectives for the study include:

• Conduct a 20-year bottom-up energy efficiency po tential study to determine the potential for

specific energy efficiency measures to reduce the consumption and peak demand of

electricity in the TVA service territory.

• Conduct a demand response potential study to determine the potential for reduction in peak

demand through demand response programs.

• Compare the potential study results with other national and regional studies, including details

regarding assumptions used to develop each of the studies.

# ANALYSIS APPROACH AND DATA DEVELOPMENT

The analysis approach for estimating demand resp onse potential is, by necessity, different from

the approach used for energy efficiency. Energy efficiency can occur outside of utility programs

to the extent that it is naturally occurring or technology driven; but can be enhanced and

enabled by utility programs. Demand response, however, does not exist without a utility

program. A program-by-program an alysis is therefore at the core of a demand-response potential

study. The basic steps used to perf orm this assessment are as follows:

1. Characterize the market. The first step is to segment the market into the relevant

customer segments. The first level of segmen tation is by sector: residential and C&I

customers. Within residential customers, we further segment the population by describing

housing types and presence of end uses (suc h as single family homes with central air

conditioning (CAC) and electric water heating). For C&I customers, the next level of

segmentation is based on the maximum dema nd values, typically following utility rate

schedules.

2. Identify baseline forecast. The second step is to identify what the peak demand forecast

will be, absent any DR programs, for both summer and winter in the TVA service territory.

3. Define relevant DR options. The next step is to identify applicable DR options for each

customer segment. DR options include direct load control (DLC), curtailable, demand

reduction, capacity reduction, load shifting, pr icing, and voltage reduction programs. Each of

these options is mapped to th e applicable customer segments . For some options, such as

DLC, specific end uses can be controlled and th ey are identified. Also, enabling technologies,

such as programmable communicating thermostats (PCT) are identified by customer

segment.

4. Outline DR program participation hierarchy. For each customer segment that has more

than one DR option, the next step is to define the participation hierarchy. This accounts for

program overlaps and ensures that cross-part icipation in DR events and double counting

does not take place.

5. Develop program parameters. Program parameters include pa rticipation rates, number of

participants equipped with enabling technology, un it load reduction impacts, attrition rates,

and DR event participation rates. Cost data are also developed for the analysis, including

program development costs, customer marketing and recruitment costs, technology costs,

customer incentives, operation and maintenanc e (O&M) costs, and program administrative

costs.

6. Estimate preliminary potential and assess cost-effectiveness. The final step is to

estimate the load reduction potential associated with each of the DR options by customer

segment, and also at the aggregate level ac ross programs and segment. Utility-provided

avoided capacity costs are used to assess benefits from DR programs.

7. Develop estimates of achievable potential. The final step is to estimate the load

reduction potential associated with each of the DR options by customer segment, and also at

the aggregate level across programs and segment. Achievable potential takes into account

expected participation rates as well as cost-effe ctiveness of the program. For this study, we

estimate a range of achievable potential:

• 

## Achievable – High assumes higher participation rates that result from application of

industry best practices in program design, higher budget limits for implementation,TVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

2-2 www.gepllc.com 

## and does not incorporate the results of th e cost effectiveness screen. Therefore,

Achievable – High represents the upper bound of savings, regardless of cost.

• 

## Achievable – Low assumes lower levels of participation as a result of limited budgets

for program implementation and includes only those programs which pass the costeffectiveness screen. Therefore the Achievable – Low represents a more realistic

picture of DR potential given barriers to participation and cost constraints.

Unlike the energy-efficiency analysis, we do not co nsider “technical” or “economic” potential for

demand response.

In the remainder of this chapter, we describe th e analysis steps in more detail. We also present

the key assumptions for estimati ng potential DR savings.



# Market Characterization of Customer Segments

The market characterization is the first step in the potential assessment an d provides insight into

how TVA customers use energy. A variety of ut ility data is used to perform the market

characterization including billing data, 8,760-hour load data by segment, energy consumption

data, and recent appliance saturation survey data.

Before analyzing the customer load and energy data, billing data is used to segment the

customers based on size and ra te. The study divided the custom ers into residential and C&I

segments with C&I customers further broken out into five subgroups:

1. Small C&I customers with a demand <= 50 kW

2. Medium C&I customers with a demand between 51 and 1,000 kW

3. Large C&I customers with a demand between 1,001 and 5,000 kW

4. Extra Large (X-Large) C&I customers with a demand greater than 5 MW

5. Direct serve customers (served directly by TVA) with a demand greater than 5 MW

The next step is to gain insight into the us age patterns of C&I customers by examining the

8,760-hour load data for 2009 provided by TVA fo r each of the six segments. Analyzing customer

demand characteristics is important because cust omer demand at a given time determines how

much load, on average, customers might be able to curtail. Table 2-1 pr esents total number of

customers in each segment in 2009, the coincident demand for each customer segment (both

summer and winter), and the average coincident demand per customer. Coincident demand

refers to the MW (or kW) load for each segment (or customer) at the time of the seasonal peak.

Residential customers have the greatest contributi on to the system peak at 47% in the winter

and 28% in the summer. Of the C&I customer s medium C&I customers have the largest

contribution with 22% in the summer and 16% in the winter. The X-large and direct serve

customers combined also represent a significant pr oportion of coincident peak load concentrated

in a relatively small number of customers. These initial observations indicate that the largest

contributors to overall potential for DR will be among TVA’s residential, medium C&I, and very

large C&I customers.TVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

## Peak Demand Forecast

Global created a reference forecast for annual coincident peak demand, for each customer

segment for the period 2010 through 2031. The refe rence forecast for peak demand is presented

below in Table 2-2. Using the reference forecast as provided by TVA (below) and the 2009 base

year values by segment (above in Table 2-1) we are able to create a reference forecast by

customer segment. 2

## Customer Forecast

Global also created a reference forecast for the number of customers in each segment for the

period 2010 through 2013. This forecast was then used to estimate part icipation rates in each

segment, by program. The customer forecast was estimated by applying growth rates 3 

## to the

2009 base year customer counts in each segment. The base year values and selected forecast

years are presented below in Table 2-3.

1 Customer counts from TVPPA database for base year of 2009.

2 The segment level peak demand forecast is created by calculatin g each classes contribution to the overall system peak in the b ase

year as calculated from the 8760 load data provided by TVA and extending that ratio into the futu re applying it to the peak fo recast in

each subsequent year.

3 Residential customer growth rates were pr ovided by TVA. Non-residential customer gr owth rates were calculated as 80% of the

growth in commercial square feet each year. This implies that increasing square footage by 1% results in a 0.8% increase in cus tomer

count. The growth rates were applied uniformly to all non-resident ial classes except X-large and Direct Serve. The growth rate for Xlarge and Direct serve customer is assumed to be half that of the Small, Medium, and Large customers.TVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

# Demand Response Options

For this study, a broad set of demand response options that combines traditional and emerging

approaches was identified. They fall into eight groups: direct load control programs, curtailable

programs, demand and capacity reduction prog rams, dynamic pricing programs, aggregator

managed programs, load shifting programs, voltag e regulation programs, and fast-DR. Table 2-4

translates the eight groups into eleven specif ic options by customer segment and identifies the

enabling technology options an d targeted end uses for each.

## The objective of these programs is to realize demand reductions from eligible customers during

the highest load hours of each summer and wint er season. Each program type provides demand

response using different load reduction and ince ntive strategies designed to target differentTVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

## types of customers. Dynamic pricing programs are voluntary both in participation and in load

response. They offer customers th e opportunity to save money on their energy bills by shifting

usage away from high load hours. Demand and capacity reduction programs are also voluntary in

nature and pay customers an incentive to reduce load during high need hours, but are targeted

specifically toward the commercial and industrial class. In a DLC program, participation in an

event is not usually voluntary, and offers a fixed payment in return for utility control of specific

end uses. Curtailable, too, pr ovides a firm load reduction through a contractual agreement

between the customer and the utility.

From the utility perspective, each of the differe nt program types can be called with different

notification times. Having a good mix of progra ms provides load reduction that can be called

under many different conditions from ancillary services, to economic dispatch. Table 2-5 shows

the notification times typically associated with the options considered in our analysis. Load

shifting is not included in the tables because it is not a dispatchable DR option. 4

## Profiles of Demand Response Options

This section describes the nine demand-res ponse options included in this study.

Direct Load Control (DLC)

In a DLC program, the program management team or system operator remotely shuts down or

cycles a customer’s CAC unit, water heater , or other smart appl iance without advance

notification. In exchange, the customer receives an incentive payment or bill credit. Operation of

DLC typically occurs during times of high peak demand or supply-side constraints. During an

event, participants’ equipment is controlled either by a one-way remote switch or by a PCT.

• The one-way remote switch is connected to the condensing unit of CAC, and to the immersion

element in a water heater. When activated by a control signal, the switch will not allow the

equipment to operate for the duration of the event. For CAC, the compressor is shut down during

an event while the fan continues to operate. This allows cool air to be circulated throughout the

home while the compressor is disabled. The oper ation of the switch is usually controlled through

a digital paging network. Most switches also contai n multiple relays so that multiple end uses can

be controlled by the same switch with inde pendent control strategies for each relay.

4 Load shifting represents a shift in load from the on-peak to th e off-peak period that occurs either on all days all year, on a ll weekdays

all year, or on all weekdays during a specific season depending on the applicable end-use.TVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

Global Energy Partners 2-7

An EnerNOC Company 

## • More recent DLC programs involve installation of a PCT or “smart thermostat” for customers.

PCTs allow remote adjustment of temperature se ttings, so the utility can remotely adjust the

temperature to reduce demand from CAC units. Afte r an event, load control is released, allowing

the thermostat to revert back to the original customer settings for temperature and schedule.

Various re-set strategies are used acro ss the country, ranging from 2°F to 8°F. 5



## Curtailable Rates

Under a Curtailable Rate option, participating customers agree to reduce demand by a specific

amount or curtail their consumption to a pre-specified level. In return, they receive a fixed

incentive payment in the form of capacity credits or reservation payments (typically expressed as

$/kW-month or $/kW-year). Customers are paid to be on call even though actual load

curtailments may not occur. The amount of the ca pacity payment typically varies with the load

commitment level. In addition to the fixed capacity payment, participants typically receive a

payment for energy reduction. Because it is a cont ractual arrangement for a specific level of load

reduction, enrolled loads represent a firm resource and can be counted toward installed capacity

(ICAP) requirements. Penalties are assessed fo r under-performance or non-performance.

This option is available to a utility's largest cu stomers, typically large industrial customers who

have flexibility in their operations. Those cust omers with 24x7 operations/continuous processes

or with obligations to continue providing service (such as schools and hospitals) are generally not

good candidates for the curtailabl e rate option. Participants need to have an interval meter in

place in order to participate.

Capacity Reduction

A Capacity Reduction program offers participan ts the opportunity to receive a credit for

voluntarily reducing load when an event is called. Customers do not pay a penalty if they are

unable to meet their energy reduction bid, although they may be under contract for a specific

quantity of load. Participants receive capacity credits for a pre-specified (usually seasonal) load

reduction that the utility can expect when an event is called. The credit is paid in $/kW/month

regardless of whether the utility calls an event. Participants in capacity reduction do not receive

any additional compensation when an event is ca lled. Events may be called on a day-of or dayahead basis as conditions warrant.

Based on program experiences from other utilities, predefined and/or preprogrammed responses

are likely to enhance customer response to capa city reduction events. Th erefore this analysis

includes an automated enablement element (Aut o-DR) in the Capacity reduction program.

Demand Reduction

A Demand Reduction program offers participan ts the opportunity to receive a credit for

voluntarily reducing load when an event is called. Customers do not pay a penalty if they are

unable to meet their energy reduction bid and are usually not under contract for a specific

quantity of load. Participants will generally plac e a bid online for the amount of load they are

willing to reduce on a particular event day, an d they usually enter bids daily during the peak

season. Events may be called on a day-of or day-ahead basis as conditions warrant. Many

utilities allow customers to enter a standing bid that is automatically entered for each event.

Participants are paid a credit for each kWh th ey reduce during the event and they are not

penalized if they do not meet their reduction bid.

Based on program experiences from other utilities, predefined and/or preprogrammed responses

are likely to enhance customer response to de mand reduction events. Therefore this analysis

includes an automated enablement element (Auto-DR) in the Demand reduction program.

5 Please note that for DLC programs with Programmable Communica ting Thermostats, it is not necessary for Advanced Metering

Infrastructure (AMI) to be in place.TVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

2-8 www.gepllc.com 

## Third Party Aggregated

Third party aggregated contracts are different from the other DR programs. A MW goal is

established for the program and a third party Curtailment Service Provider (CSP) is contracted to

meet that MW reduction goal. The third party provider is generally responsible for program

implementation, recruitment, and technology enablement. The program itself could take the form

of any of the DR program described in this section, however in our experience, demand

reduction style programs are the most common. Third party aggregated programs provide the

utility with a firm capacity reduction when called upon, but require the CSP to balance a portfolio

of participants to achieve that reduction. In this way the pr ogram shifts the risk of nonperformance from the utility to the CSP.

Distributor Aggregated

Distributor Aggregated demand response follo ws the same principals as the third party

aggregated program except instead of a CSP, TVA is contracting with one of their distributors.

Fast DR

The Fast DR program is a technology overlay which can be applied to any of the dispatchable,

customer based, demand response options. In or der to be considered Fast DR the technology

must be able to provide a load response within 10 minutes or less of the event notification.

Loads participation in Fast DR programs can be nominated to serve as operating reserve and

need to be shed within the response time spec ified (instantaneous to 10 minutes). The short

timeframe of response necessitate loads to be equipped with advanced and automated control

features, such as Auto-DR, along with extr emely advanced metering and communication

capabilities.

In our analysis, we consider Fast DR events separately from other traditional DR events.

Traditional DR events can be called with advanced notice in response to forecasted high load or

high prices. Fast-DR events, on the other hand, are called in response to immediate and severe

system emergencies which could oc cur at any time. Therefore customers that participate in FastDR are actually a subset of participants in other DR options with enabling technology that allows

for a response time of less than 10 minutes. Cons equently, Fast DR potential is also considered

separately and cannot be adde d to the total potential.

Dynamic Pricing

Dynamic pricing in this study refers to the critical peak pricing (CPP) option, which uses price

signals in the form of high prices during relatively short critical peak periods to encourage

customers to reduce their usage on event days. The customer incentive is a larger discount

during off-peak hours throughout the year. Event days are dispatched on relatively short notice

typically for a limited number of days during the year. Usually the timing is unknown. However,

over time trigger criteria are well-established so that customers can expect events based on the

weather or other factors. Events can also be ca lled during times of sy stem contingencies or

emergencies. Notification of an event can either be day-ahead or day-of. For participation in this

option, customers must have ad vanced meters, and customers ar e considered eligible for the

CPP program after their AMI meter has been insta lled. This analysis assumes that all pricing

program participants are equipped with enabling technology, which is PCT in the case of

residential/small C&I customers and automate d demand response (Auto-DR), implemented

through energy management and control systems, in the case of medium/large C&I customers.

PCTs allow automatic responses to critical peak prices. Auto-DR can be used in any pricing

program by enabling automatic response to pricing signals through pre-programming of

customer choice and preference s in the response strategy.

Load Shifting

The Load Shifting program includes a permanent technology enabled shifting of load from the

on-peak to the off-peak period. This load shift could occur only during the summer months or,TVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

Global Energy Partners 2-9

An EnerNOC Company 

## might occur all year long depending on the end-use being shifted. The technology employed

could be as simple as a timer used to shift pool pu mp load to the off-peak period. Or, it could be

very complex, such as using ice or thermal st orage to shift large commercial HVAC load. This

program is not dispatchable therefore no event ca lling strategy is assume d. Compensation for a

load shifting program is usually a combination of rebate based incentives and time-differentiated

rates. The utility covers some portion (up to 10 0%) of the shift enabling technology, generally

paid $/kW shifted, and customer benefits from lower off-peak energy rates.

Voltage Regulation

Voltage regulation is a program that produces energy and demand savings at the distribution

level. The utility achieves savings by lowering service voltages at distribution feeders thereby

reducing the real energy delivered to customers without compromising power quality. Some

examples of measures include installation of shunt capacitors to improve power factor,

installation of line regulators, implementation of line drop compensati on voltage controls, and

installation of voltage metering at feeders. In this study we consider two types of voltage

regulation. Conservation Voltage Regulation (C VR) implies improvements that are always on,

similar to energy efficiency, and Dispatchable Voltage Regulation (DVR), which could be turned

on, in the case of a system emergency or forecasted high load conditions.



## Program Participation Hierarchy

To avoid double counting of impacts, program-e ligibility criteria were defined to ensure that

customers cannot participate in multiple programs. For example, residential customers cannot

participate in both an air conditioning DLC pr ogram and a dynamic pricing program, which both

target the same load on the same days. Fast DR is the one exception; it is denoted as distinct

from other DR programs, which means that customers can participate in both a traditional DR

and a Fast DR option. We allow fo r dual participation in this particular option because Fast DR

events are assumed to occur at different times than traditional DR events. Table 2-6 indicates

the eligibility criteria by customer segment for the DR options applicable to each segment.TVA Energy Efficiency Potential Study, Volume 3 Analysis Approach and Data Development

## Participation Rates

A key driver for the amount of DR potential is th e participation rate for each program. In this

study it was important to assess participation at two levels, both at the distributor level, and at

the end-user level. End-user pa rticipation rates reflect the total number of customers that are

likely to participant in a program within a specific distributor’s territory. Distributor participation

rates reflect the total percentage of distributors that we expect, on average, might choose to

offer a particular DR option. Distributor participation rates were based on industry knowledge

and collaborative discussi ons with TVA Staff.

End-user participation rates were developed as follows.

• Assumptions for 2012 . For existing DR programs of a particular type, end-user participation

rate assumptions in 2012 are benchmarked to current levels of load reductions. That is, the

existing program achievements fall within the range of Achievable potential.

• Achievable – High . Where there are no existing programs in place, the participation rates

under Achievable - High level are based on th e FERC report’s Expanded Business As Usual

(EBAU) scenario for Tennessee. 6 

## The Expanded Business-As-Usual (EBAU) scenario assumes that

existing programs continue into the future bu t are implemented such that “best practices”

participation levels are achieved. In the FERC National Potential Study, the best practice

participation rate was assumed to be equal to the 75th percentile of ranked participation rates of

existing programs of the same type and custom er class across all states. The AMI deployment

schedule is also based on EBAU scenario values from the FERC study and we assume that 80%

of the eligible customers with AMI participate in pricing programs.

• Achievable – Low . Participation rates were adjusted to reflect a more moderate enrollment in

specific DR options based on industry experience.

In all cases, participation rates ramp up until 2020 and remain steady thereafter.

Table 2-7 and Table 2-8 present participation ra tes for TVA’s service territory by class and,

program and both the distributor and end-user levels for the high and low case. The effective

participation is calculated as the distributor part icipation multiplied by the end-user participation

in both cases. Also note that the participation rates in Table 2-6 represent the percent of eligible

customers and those in 2-7 represent the percent of eligible MW. 7

6 The FERC recently conducted a national study of demand response potential referenced in this report as the FERC National Deman d

Response Report or simply the FERC Report.

A National Assessment of Demand Response Potential, Prepared by: The Brattle Group, Freeman, Sullivan & Co, and Global Energy

Partners for the Federal Energy Regulatory Commission, June 2009.

7 For the X-large and Direct serve customers all the potential anal ysis was performed based on a market size of MW rather than

participation and potential to current participation. A similar approach was used in the FERC National Demand Response study to

# Framework for Cost-Effectiveness Assessment

The DR programs were assessed for cost-effectiveness drawing upon the California Standard

Practice protocol for DSM econom ic assessment. For the purpos es of this study, the Total

Resource Cost (TRC) test was applied to assess the benefits and costs associated with the DR

programs. The Total Resource Cost (TRC) test me asures benefits and costs from the perspective

of the utility and society as a whole. Since util ities customers are taken as a whole, changes in

the dollar amounts that flow between them (trans fer payments or in this case rebates) are

ignored. Programs passing the TRC result in a decr ease in the total cost of energy services to all

electric ratepayers.

The benefits used in the TRC test for this analys is are made up solely of the avoided capacity

benefits attributable to the impacts of the pr oposed programs from the high achievable case 11



## . Energy benefits and external benefits were not considered in this analysis. The costs are made

up of any customer incentives, costs attributable to the purchase and installation of enabling

technologies, and, general administrative costs.

The cost-effectiveness analysis wa s performed at an aggregate leve l, representing the potential

effects of each individual demand response program in the portfolio. A spreadsheet model was

used as the primary tool for conducting th e cost-effectiveness assessment. The detailed

assumptions related to cost-effectiveness assessment are presented in Appendix A.



## Economic Data Supporting DR Cost-Effectiveness Assessment

In our approach we estimate the Net Present Valu e (NPV) of costs and benefits associated with

each of the DR programs from the Total Resource Cost test perspectives . All cost and benefit

values were escalated for inflation at an annuali zed forecast GDP growth rate of 1.86%. Discount

rates, line loss factors, avoided capacity, and avoided energy costs were provided by TVA and

incorporated into the analysis to estimate net DR potential.

11 We compute B/C ratios under the high case assumptions, which provide the best opportunity for programs to be cost-effective.

Programs that pass the cost-effectiveness screen under the high scenario will not necessarily pass under the low scenario.Global Energy Partners 3-1

## CHAPTER 3



# RESULTS OF DR POTENTIAL ANALYSIS

This chapter presents the estimates of DR pote ntial for the service territory of the Tennessee

Valley Authority.



# Summary of Demand Response Potential

Demand response has the potential to reduce peak demand by 1,169 MW to 1,280 MW in 2012.

The achievable potential increases to a range of 2,890 MW to 4,300 MW in 2030. 12



## Table 3-1 presents the overall summary of demand response potential for the two cases. Figure

3-1 presents this information graphically. The primary observations are:

• In summer of 2012, achievable potential reduces peak demand by approximately 4%. This

starting point takes into account the achiev ements in 2011 from TVA’s current DR program

portfolio.

• By summer of 2030, the achievable potential reduces peak demand by 9% to 11%. This level of

savings represents an offset in growth of between 49% and 59%.

• In winter of 2012, achievable potential reduces peak demand by approximately 4%.

• By winter of 2030, the achievable potential reduces peak demand by 8% in the low case and 9%

in the high case which represents an offset in growth of between 48% and 55%.

Detailed annual results of the potential analysis are provided in Appendix C.

dispatchable DR program, therefore the impacts associated with DR cannot be added to the total potential and they will be discu ssed

separately in a subsequent section.TVA Energy Efficiency Potential Study, Volume 3 Results of DR Potential Analysis

## Figure 3-1 Summary of Demand Response Potential for TVA



# Potential Estimates by DR Program Type

Table 3-2, Table 3-3, Figure 3-2, and Figure 3-3 show the range of achievable potential for each

program type in both summer and winter. The primary observations from the analysis are:

• Capacity reduction has, by far, the largest contribution to the overall potential from all DR

programs, with a 37% share in the total achievab le potential in the high case in 2030. The

achievable potential for this program represents a migration from the curtailable program to the

capacity reduction program by 2016. 13



## • The Curtailable program is phased out completely by the year 2016 as all participants migrate

into the Capacity Reduction option. In our experi ence, this trend is common in the industry as

many utilities move away from emergency response programs and toward programs that can be

integrated into wholesale markets ba sed on economic dispatch models.

• While the total potential attributable to DLC va ries widely from 645 MW and 18% in the low case

to 1,174 MW and 27% in the high case DLC rema ins the second largest contributor to overall

potential. The key difference between estimates of potential in the high and low case is the

participation rates. The high case assumes an e ffective participation of 23.1% while the low case

assumes an effective participation of 11.3%. DL C potential also varies widely from summer to

winter; this is a result of the saturation of central air conditioning in the Tennessee Valley being

higher than the saturation of electric heat.

• The Voltage Reduction programs also contribute substantially to the overall potential with CVR

contributing 13% and DVR contributing 5% to overall potential.

• Savings from the Third Party Aggregated program come in fourth with a 6% share of the total

potential in 2030. When combined with the Distribu tor Aggregated Program, which is very similar

to the Third Party Program, the two programs represent 9% of the total potential in 2030.

• Savings from the Dynamic Pricing program are modera te with a total contribution of about 5% in

2030. Under a voluntary scenario, we assume a very conservative participation rate which limits

the potential of this program type.

• Load shifting and Demand Reduction have the sma llest contributions to overall potential each

with about a 2% contribution in 2030.

13 This migration is representative of the migration of custom ers from TVA’s current 5MR and 60MR programs to the new Reserve

Preservation program which falls within the capacity reduction program option for this study.

# Potential Estimates for Fast DR

Because the Fast DR program is made up of a subs et of participants from other DR programs the

potential from this program cannot be added to the total potential and is therefore addressed

separately in this section. Table 3-4, Table 3-5, Figure 3-6, and Figure 3-7 show the range of

achievable potential for Fast DR by customer class for both summer and winter. The primary

observations from the Fast DR analysis are:

• Direct Serve is the largest contributor to the tota l potential for Fast DR by a wide margin with

54% of the total potential reduction in 2030. Th is takes into account current participation in

TVA’s Instantaneous Response program which amounts to approximately 200 MW in 2011.

• Residential is the second largest contributor to the total potential with a contribution of 17% in

2030. Residential customers who participate in DL C are prime targets for Fast DR since they

already have a significant portion of the necessary enabling technology installed. 14

14 The California Participating Load Pilot showed that residential and small commercial DLC participants can be used as a Fast DR

resource suitable to be bid into the CAISO market as an ancilla ry service with minimal modification and investment. Customer Im pact

# COST-EFFECTIVENESS ANALYSIS

Summary of Cost-Effectiveness Analysis Results

Table 4-1 presents a summary of the cost-effect iveness results based on the TRC test for all

programs. 15 

## The cost effectiveness tests were perf ormed using a bottom up approach that

employs cost assumptions based on secondar y information and industry best practices. 16 

## The

analysis was performed in this manner in order to provide TVA with realistic annual costs that

can be passed on to distributors including: equi pment costs, incentive co sts, administrative, and

marketing costs 17 

## . The results of the TRC test analysis show that the overall portfolio of DR

programs is cost-effective. 18 

## The cost-effectiveness assessment is done for the Achievable - High

level.

The most cost effective programs are Curtaila ble, Capacity Reduction, Demand Reduction,

Dynamic Pricing and Fast DR. Curtailable has th e highest B/C ratio due to a shortened program

life of three years. Demand Reduction, Capacity Reduction, and Dynamic Pricing are also highly

cost effective. These programs have lower admini strative costs, and fewe r equipment costs than

the other non-aggregated programs . The voltage regulation progra ms are also considered cost

effective, however it is important to note that costs for these programs are based solely on the

incentive payment that TVA pays to the distribu tors. All equipment and im plementation costs are

assumed to be covered by that incentive and addi tional external (rate-based) costs and benefits

to the distributor are not captured. The remain ing programs; DLC, Third Party and Distributor

Aggregated, and Load Shifting, are all cost effective with B/C ratios ranging from 1.05 to 1.31.

16 Cost effectiveness inputs and assumptions are included in Appendix A.

17 While utility incentives are not included in the TRC test as co sts, we provide estimates of incentives that could reasonably b e

assumed for each program in the appendix.

18 The $/kW payment for the Dist ributor aggregated program was ad justed from the $63/kW year in the TVA provided program data

sheet to $55/kW year in order for the program to pass the econ omic screen. The Distributor Aggregated program was not cost

effective given our assumptions in the analysis at the higher in centive rate. Payments from the utility to aggregators for both the 3 rd

Party Aggregated and Distributor Aggregated programs are included as implementation costs in the TRC analysis.TVA Energy Efficiency Potential Study, Volume 3 Cost-Effectiveness Analysis

4-2 www.gepllc.com 

## We also provide a levelized cost per kW for each program in Table 4-2. Levelized costs represent

the ratio of cumulative program costs to cumula tive estimated kW impacts. These costs can be

used to assist TVA in determining realistic incentiv e levels to offer distributors which will result in

cost effective programs. The levelized cost resu lts mirror the TRC test results with Curtailable

having the lowest levelized cost at $3/kW and Distributor Aggregated having the highest

levelized cost at $68/kW.

# PROGRAM RECOMMENDATIONS

The results of the DR assessment reveal that TV A has significant potential for demand response

resources over the next two decades. Our analysis has shown that it is economically feasible for

TVA to realize up to 11% reductions in summer pe ak and 9% reductions in winter peak by 2030

if it moves forward with the DR options represented in this report.

TVA’s demand response programming efforts have a strong basis with larg e C&I customers in the

field today. Moreover, a comprehensive suite of new programs is currently emerging from the

planning phase and entering the im plementation phase. In light of this study, Global provides the

following recommendations to preserve and augment that momentum.

• Expand programs to include smaller customers: TVA’s current DR programs total

approximately 1,300 MW of DR, which indicates that the potential for future success with

new DR programs is very high. The majority of the currently installed DR capacity is

concentrated in the Large, X-Large, and Di rect Serve customers. Targeting the largest

customers first is an excellent strategy for utilities as they begin their DR efforts, however, as

portfolios mature it becomes necessary to target other customer segments such as

residential and small and medium C&I.

• Focus efforts on programs with the largest potential: DLC and Capacity Reduction are

the DR programs with the largest opportuni ty for savings among end-users. DLC is a

program that can be targeted to residential and small commercial customers and has been

shown to be very successful given the right combination of technology and incentives. 19



## Capacity reduction is gaining ground on the we st coast as a highly favorable program with

commercial and industrial customers. Customer s particularly like the monthly capacity

payments they receive all year long and the flexibility to determine their own reduction bid.

Marketing efforts to expand DR program partic ipation to the smaller customers should focus

on DLC and capacity reduction.

• Voltage regulation programs need carefully designed incentives: Voltage reduction

has significant potential to reduce demand on the distribution side. This is a unique program

in that it involves infrastructure improvements to optimize and reduce voltage levels without

affecting the power quality ultimately distributed to end users. Sufficient incentives will be

needed to encourage distributors to partic ipate in this program and therefore more

information on the cost of specific voltage regulation technologies will need to be gathered.

• Coordinate distributor layer between TVA and end user: Because TVA is a wholesale

provider, maintaining a cohesive DR message to end users may be challenging, especially as

DR programs focus on residential and sma ll C&I customers. We recommend dedicated

resources to ensure that TVA programs are marketed and implemented consistently across

distributors.

• Create internal DR targets: TVA should continue to evolve and formulate its specific

objectives regarding demand response by creating targets and goals. Global recommends

targets that fall within the range of achievab le potentials identified in this study.

• Consider limiting the number of programs: TVA has a longer list of DR programs than

many utilities do. TVA may consider limiting the number and type of DR programs to

facilitate distributor and end-user understanding. Customers are often overwhelmed by too

19 Southern California Edison, NV Energy, Florida Power & Light, an d others all have very successful DLC programs with participat ion

rates of 20% or more.TVA Energy Efficiency Potential Study, Volume 3 Program Recommendations

5-2 www.gepllc.com 

## many options when it comes to utility programs, and many utilities with a large number of

programs are now focused on reducing or bund ling programs to make participation simpler

for customers. We recommend focusing on th ose programs with th e highest potential:

capacity reduction in the C&I sectors, DLC in the residential sector, and voltage reduction for

the distributors.

• Provide market-friendly customer incentives : Most customers are willing to offer their

loads for participation in demand response prog rams if the utility is willing to compensate

them for any inconvenience that they may rea lize due to the temporary service interruption.

While incentive strategies must be structured in a way that ensures economic viability for the

program, we have found that there is signific ant room to expand customer incentives while

still maintaining cost-effectiveness.

• Provide enabling technology incentives: Enabling technology has been shown to

improve the reliability of DR resources and to maximize load reduction in DR programs. It is

therefore crucial to provide incentives to customers for adopting enabling technology in order

to automate response to DR events.Global Energy Partners 6-1

# COMPARISON OF PREVIOUS POTENTIAL STUDIES

Previous studies of energy efficiency potential for the Valley and for the southeast region have

produced a range of results. As part of this potential assessm ent, TVA requested that Global

develop a comparison of several key recent studie s to better understand how the studies differ in

their approaches and thus why their results differ as well. Table 6-1 presents an at-a-glance

comparison of this study with other relevant studies of the southeast and the nation as a whole.

# Tennessee Valley Authority Energy Efficiency and Demand Response

Potential Study — Global TVA (This Study)

We begin by briefly summarizing our own study in the same manner as we will summarize the

comparison studies.

The Global TVA study was conducted and published in 2011. It estimated EE and DR savings

specifically for the TVA service territory. The base year for the study was 2009 and the forecast

horizon was 2009 through 2030, with program activi ty beginning in 2012. The contractors for the

study were Global Energy Partners, LLC and The Brattle Group.

Analysis approach – The study used a detailed bottom- up analysis approach. Analysis was

performed at the sector, segment, and DR option levels. TVA data, national data, and previous

Global studies provided the inputs to th e market characterization and analysis.

Baseline forecast – The peak demand forecast was taken directly from the TVA forecasting

group and checked against the 2011 Annual Energy Outlook. It includes the affects of building

codes and appliance standards in place in 2010, most notably the EISA lighting standard. The

baseline does not include naturally occurring efficiency.TVA Energy Efficiency Potential Study, Volume 3 Comparison of Previous Potential Studies

6-2 www.gepllc.com 

## Levels of potential – A range of achievable potentials was developed: between Achievable –

Low and Achievable High, based on a range of anticipated levels of customer adoption and

incentive payments.

Study Findings – The table below summarizes the demand response savings for the different

levels of potential relative to the baseline forecast.

# A National Assessment of Demand Response — FERC

This study was commissioned by FERC and publishe d in 2009. It presented the first nationwide

assessment of demand response potential using a state-by-state approach along with a publicly

available tool for updating the potential. The st udy estimated demand response potential within

a 10-year timeframe, identified barriers to deployment of DR programs and provided specific

recommendations for addressing those barriers. The contractors for the study were The Brattle

Group, Freeman Sullivan and Company, and Global Energy Partners, LLC.

Analysis approach – The potential estimation was based on a detailed bottom-up analysis of

demand reduction associated with DR programs at an individual state level. The aggregate of the

state-level potentials represented the national potential. A state-by-state database was

developed containing all inputs needed to do a detailed bottom-up assessment of DR potential.

An excel-based tool was developed to estimate DR potential at four levels (discussed below) by

state and by DR programs. Broadly, four types of DR programs were considered- Direct Load

Control (DLC), Interruptible Tariffs, Dynamic Pricin g, and Other DR programs (including Capacity,

Demand Bidding, and other types of aggregator offerings). The analysis estimated potential by

four customer classes- residentia l, small C&I, medium C&I, and large C&I classes based on rate

definitions.

The timeframe of the study was from 2009 to 2019.

Baseline forecast – The baseline forecast, which excludes the effect of demand response but

includes the effects of energy efficiency, was derived from NERC’s data on total summer demand

forecast, presented in the agency’s 2008 Long Term Reliability Assessment Report.

Levels of potential – Four levels of potential were estimated:

• Business-as-Usual assumed th e continuation of existing programs at their current levels of participation

and included no increase in demand response.



## • Expanded Business-as-Usual assumed that utilities would adopt “best practices” in existing demand

response programs. In this case, the set of DR programs in 2019 was the same as in 2009.



## • Achievable Potential expanded the set of DR pr ograms to include dynamic pricing programs and

assumed they would be implemented on an “opt-out ” basis. Other programs and their participation

were adjusted to account for the availability and adoption of dynamic pricing options. The level ofTVA Energy Efficiency Potential Study, Volume 3 Comparison of Previous Potential Studies

### potential in each state varied according to the timeline for deployment of advanced metering

infrastructure (AMI).



## • Full Participation was similar to Achievable Potential but it assumed 100% participation in dynamic

pricing programs when they became available to customers.



## Study Findings – Study results are as follows:

Comparison to Global TVA Study – The results for this study ar e moderately comparable to the

Global TVA study. They both use detailed, bottom-u p analysis methods. They use different definitions

of potential, however, but arrive at simila r ranges of achievable peak demand savings.



# Assessment of Demand Response and En ergy Efficiency Potential for

Midwest ISO and the Eastern Interconnection — MISO

This study was commissioned by Midwest ISO (MISO) and published in 2010. It addressed

MISO’s need to develop 20-year load forecast s that account for dema nd response (DR) and

energy efficiency (EE) activities in the Midwest ISO region and for the Eastern Interconnection.

The study presented demand and energy savings potential associated with a set of DR and

energy efficiency programs over 2010-2030 for the MISO region as well as for the Eastern

Interconnection. The contractor for the study was Global Energy Partners, LLC.

Analysis approach – For the MISO region, the study developed estimates of DR and EE savings

over 2010-2030, using program information obtained from utilities within the region. For the

Eastern Interconnection area, a variety of secondary resources were used to develop estimates

of potential. For the Midwest ISO region, the study used a detailed bottom-up estimation

framework, primarily based on survey data from utilities in the region. For the Eastern

Interconnection analysis, the FERC National Assessment of DR Potential was used as the primary

source of information to derive potential estima tes. This was done by aggregating state-level

potential data into the appropriate Eastern Inte rconnection planning areas. A total of five

different DR program types were considered in the analysis to be in line with the Midwest ISO’s

planning model- residential DLC, residential pric ing, C&I DLC, C&I Curtailable/Interruptible, and

C&I Pricing. The timeframe of the study was from 2010 to 2030.

Baseline forecast – For the Midwest ISO region, the baseline forecast was developed based on

forecast data provided by utilities in the region. For the Eastern Interconnection area, the

baseline forecast was grounded to the FERC Nati onal Assessment of Demand Response Potential

Report.

Levels of potential – The study developed estimates of achievable potential.

Study Findings- The savings from DR programs for the Midwest ISO region and Eastern

Interconnection area are summarized in the table below.TVA Energy Efficiency Potential Study, Volume 3 Comparison of Previous Potential Studies

Comparison to Global TVA Study – The results for this study ar e moderately comparable to the

Global TVA study. They both use detailed, bottom-up analysis methods. The MISO study also has

some limited regional specificity in that it looks at the Eastern Interconnection. Both studies arrive at

similar ranges of achievable peak demand savings.Global Energy Partners
