I will explain the generally accepted methodologies used for determining energy effciency program cost effectiveness and whether the Company conforms to these methodologies; and, . I will demonstrte the cost effectiveness of the Company's Idao DSM programs and why they are prudent and in the public interest. Are you sponsoring an exhibit as part of your direct testimony? Yes. I am sponsoring Exhbit No. 56 which was prepared under my supervision and diection. Exhbit No. 56 documents the benefits, costs and cost-effectiveness results of Rocky Mounta Power's Idao DSM programs. Hedman, Supp - 2 Rocky Mountain Power 1 Q.Is this prudency fiing consistent with the memorandum of understanding 2 (MOU) for prudency determination of DSM expenditures that was signed by 3 Rocky Mountain Power, Avista and Idaho Power in December 2009 and by 4 the Idaho Public Utilties Commission staffin January 2010? 5 A.Yes, the fiing is consistent with the MOD. Rocky Mountain Power filed anual 6 reports in March of 2009 and March of 20 1 0 for program years 2008 and 2009 7 respectively. These reports provide the narrative program descriptions, costs, 8 savings and cost effectiveness anticipated by the MOU. The 2009 report also 9 includes the status of the impact and process evaluations. 10 Overview of Idaho DSM Programs 11 Q.Please provide an overview of Rocky Mountain Power's Idaho DSM 12 program portfolio. 13 A.Rocky Mountain Power's Idaho DSM portfolio consists of eight distinct programs 14 offering incentives for a wide variety of energy efficiency measures and 15 parcipation in load management programs to the Company's residential, 16 business and agrcultural customers. Rocky Mountain Power continues to work 17 with their customers and the Idao Public Utilities Commission ("Commssion") 18 to provide a comprehensive suite of DSM programs that provide the greatest 19 opportty for paricipation by all customer sectors. 20 Q.What DSM programs are available to Rocky Mountain Power customers 21 subject to the Electric Servce Schedule No. 191, Customer Efficiency 22 Servces Rate? 23 A.The Company offers eight DSM progrs, consisting of three residential, thee Hedman, Supp - 3 Rocky Mountain Power 1 agrcultural, and two business programs. Collectively, the programs offer a wide 2 range of services and financial support capable of assisting customers with 3 virtally any energy efficiency project they wish to pursue. The eight DSM 4 programs are as follows: 5 Residential Programs 6 Schedule 21 - Low Income Weatherization 7 Schedule 117 - Refrgerator/Freezer Recycling 8 Schedule 118 - Home Energy Savings Incentive 9 Agricultural Programs 10 Schedtie 72 - Irrgation Load Control Credit Rider 11 Schedule 72A - Irgation Load Control Credit Rider Dispatch Program 12 Schedule 155 - Agrcultual Energy Services 13 Business Programs 14 Schedule 115 - FinAswer Express 15 Schedule 125 - Energy FinAswer 16 In addition to the eight programs, the Company's Idao porton of the Northwest 17 Energy Effciency Alliance (NEA) sponsorship is fuded though the revenues 18 collected from the Customer Effciency Service Rate. With the exception of the 19 Energy FinAwer program as modified to provide incentives, Schedule 125, 20 (available to Idaho customers begig in May, 2008) these programs are 21 ongoing and represent the same progr portfolio for which prudency was 22 determined for program years 2006 and 2007 in Case No. PAC-E-07-05, 23 Commission Order30482. Hedman, Supp - 4 Rocky Mountain Power 1 Q. 2 A. What were the Company's DSM results for 2008 and 2009? Energy efficiency program savings at the meter (including NEEA) in 2008 were 3 10,389 MWH and in 2009 were 14,744 MWH. Rocky Mountain Power's 4 irrgation load management programs (Schedules 72 and Schedule 72a) had 5 partcipating loads under managementof215 MW in 2008 and 258 MW in 2009. 6 Cost Effectiveness Methodology 7 Q. 8 9 A. 10 11 12 13 14 15 16 17 Q. 18 A. 19 20 21 22 Q. 23 A. What is the general approach to analyzing the cost effectiveness of demand- side management programs? Utilities can meet their futue load requirements by increasing their supply of energy through new generation and purchased power or by reducing those futue load requirements through energy efficiency and load management programs (together referred to as demand-side management or DSM) or by a combination of new supply and DSM. In order to determine the optimal mix of new supply and DSM, the utility must compare the costs of both their supply and demand side options. If the cost of a DSM program is lower than the cost of acquirig additional supply the DSM program is determined to be "cost effective". How is cost effectiveness ilustrated? Cost effectiveness is ilustrted though multiple cost-benefit tests. Results are displayed as the net benefits or as a ratio of benefits to costs. A ratio of the benefits ofthe resource to the costs of the resource that is greater than 1.0 demonstrtes a resource is cost effective when compared to the alternatives. What tests are commonly used to determine cost effectiveness? It is informative to view cost effectiveness from different perspectives. Typically, Hedman, Supp - 5 Rocky Mountan Power 1 2 3 4 5 6 7 8 Q. 9 A. 10 11 12 13 14 15 Q. 16 17 A. 18 -19 20 21 Q. 22 23 A. cost effectiveness is tested from the utility, paricipant, non-participant and all customers' perspective. These tests are referred to as the Utilty Cost Test (UCT), Participànt Cost Test (PCT), Rate Impact Measurement (RIM) and Total Resource Cost Test (TRC). A variant on the TRC, called the Societal Cost Test, is often calculated as welL. The Societal Cost Test expands on the TRC by adding quantifiable non-energy costs and benefits, such as emissions reduction. Another reference for this test is TRC + Conservation Adder. Is there a generally accepted formulation of these tests? Yes. Californa was fist state to formally adopt the tests described above. In 1983 the California Public Utilities Commssion first published the Stadard Practice Manual with mathematical formulations for each of the tests. Since then, the formulations contained in that manual have become the industr standad formulation. The most curent version of the manual is the 2001 version. The formulations are not specific to California. Does Rocky Mountain Power's cost effectiveness analysis conform to the standard tests? Yes. The models and inputs used by Rocky Mountain Power are based on the California formulations of the cost effectiveness tests. The Total Resource Cost test is presented both with and without a 10 percent adder that reflects non- quantified benefits. How do the tests account for a customer who would have made an energy effciency investment without receiving a program incentive? Each of these tests is calculated based on a "but for" case. That is, ''but for" the Hedman, Supp - 6 Rocky Mountain Power 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Q. 15 A. 16 17 18 19 Q. 20 A. 21 22 23 program, what would have happened? In most instances, DSM programs provide information and incentives to customers to encourage the purchase or adoption of energy efficiency measures and practices. Absent the program, some of these customers would have purchased the measures or undertaken the practices on their own accord. It would not be appropriate to credit the program with changing these customers' behavior. If they receive an incentive from the program for these actions, absent program influence, they are considered "free-riders". In other words, it was not necessary for the utility to provide these customers with an incentive and the utility should not get credit for their actions. Energy savings from free-riders are not included in the total program energy savings for the puroses of cost-effectiveness determination and customer costs associated with free-riders are not included in the program costs. Any payments by the utility to the customer are included as costs of the program, however. How is free-ridership quantified? Free-ridership is expressed as a net-to-gross factor that combines the impacts of the free-ridership (incentive recipients that would have purchased the energy efficiency measure with no incentive) and spilover (additional purchases influenced by the program but for which no incentive is paid). How are net-to-gross factors estimated? In the planng phase net-to-gross assumptions are derived from sources such as prior evaluations of the Company's progrs and the Data Base of Energy Effciency Resources (DEER), which contain the results of hundreds of program evaluations. These ar tyically the factors used in program filings. Net-to-gross Hedman, Supp - 7 Rocky Mounta Power 1 2 3 4 Q. 5 6 7 A. 8 9 10 11 12 13 14 15 16 17 Q. 18 19 A. 20 21 22 23 factors are estimated through post implementation evaluation of programs. Customer interviews and market analysis are used to estimate the free-ridership and spilover. Is Rocky Mountain Power's process for determining annual savings and cost effectiveness consistent with the process used by utilties in other jurisdictions? Yes. The process used by Rocky Mountain Power in its anual report is consistent with that used by other utilities. The costs reflect the actual expenditues incured by the company while the savings are based on an estimate derived from the planng assumptions. Rocky Mountain Power reviews program costs and participation throughout the program year and adjusts the programs to reflect changes that occur. In addition, Rocky Mountain Power performs thrd party process and impact evaluations of the programs consistent with the terms of the MOU. These evaluations help the Company fuher refine the progrs to increase paricipation, increase energy savings acquisitions and maintain or improve their cost effectiveness on an ongoing basis. How do Rocky Mountain Power's Idaho programs compare to other programs Cadmus has assessed cost effectiveness of or evaluated? Cadmus has evaluated and assessed the cost effectiveness of hundreds of programs implemented by utilities nationwide, including PacifiCorp's. The Company's programs are designed using widely accepted practices that aim to maximie paricipation while mimiing utility costs and rate impacts. Mid- coure adjustments to the programs are noted in the anual report and indicate Hedman, Supp - 8 Rocky Mountain Power 1 that the Company continuously monitors the programs to assure program 2 relevance, market acceptance and cost effectiveness. 3 Idaho DSM Investment Prudency Demonstration 4 Q. 5 6 A. 7 8 9 10 11 Q. 12 13 A. 14 15 16 17 18 19 Q. 20 21 A. 22 23 Why is Rocky Mountain Power requesting a finding of prudence for their DSM investments in this case? In Order No. 32023 approving the 1 percent increase in the Company's Schedule No. 191, Customer Efficiency Servces Rate, the Idaho Public Utilities Commission ordered "that the Commission reserves questions of the prudency and cost-effectiveness of the Company'sDSM programs and expenditues for the Company's pending rate case (PAC-E-1O-07)". Have the Company's Idaho DSM program's undergone any reviews or evaluations? Yes. The Company has conducted reviews of the load management programs through annual program reports and presentations to the Idaho Public Utilities Commission staff. Program performance results, including cost effectiveness assessments, were also fied on the Company's DSM program portfolio for the calendar year reporting periods of 2008 and 2009. In addition, Cadmus is conducting an evaluation of the 2006-2008 energy effciency programs. Have these reviews and the analysis results shown in Exhibit No. 56 found Rocky Mountain Power's Idaho DSM programs are cost-effective? Yes. The portfolio of programs is cost-effective from both a Total Resource Cost (TRC) and Utilty Cost Test (UCT) perspective. Exhibit No. 56 shows that the TRC benefit-to-cost ratio for the overall DSM portfolio for 2008 and 2009 Hedman, Supp - 9 Rocky Mountain Power 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Q. 19 A. 20 21 22 combined (load management and energy efficiency, excluding NEEA costs and savings) is 3.7, with a net TRC benefit to customers of over $32 milion (Exhibit No. 56, Table 2). The TRC and UCT cost for the load management programs were $ 14.53/kW-yr and $43.24/kW-yr, respectively, and can be compared against utility avoided costs of$67.05/kW-yr (Exhibit No. 56, Table 3). The 1eve1ized TRC and UCT cost of the energy efficiency programs were 6.5 cents and 4.4 cents per kWh, respectively, compared against utility avoided costs of 8.8 cents (Exhbit No. 56, Table 3). Though allowed by the Californa cost effectiveness formulations, the benefit-to-cost ratios do not include "non-energy benefits or other fuel benefits and are calculated utilizing net savings, i.e., inclusive of the impacts of free-ridership and spilover. This presents a conservative estimate of the program's cost effectiveness. As an overall portfolio, the DSM investments were also cost-effective from both a Rate Impact Test (RI) and Participant Cost Test (PCT) perspective with benefit-to-cost ratios of 1.372 and 11.436, respectively (Exhbit No. 56, Table 2). The energy effciency portfolio was cost-effective under all cost tests except the RIM test where the benefit-to-cost ratio was .68 (Exhbit No. 56, Tables 4 and 5). Are the process and impact evaluation of these programs complete? No. The process and impact evaluations are in various stages of completion. Field work, sureys and data analysis are largely complete and the quality assurance process is underway. I expect the results to be finalized by the end of the year. Hedman, Supp - 10 Rocky Mountain Power 1 Q. 2 A. 3 4 5 6 7 8 9 10 11 12 13 14 Q. 15 A. Please summarize your conclusions. The Company's expenditures of Schedule 191 revenue (and the fuds utilized for irrgation load control participation credits) have been reasonable and prudent. A portfolio of programs covering all customer classes has been offered with total savings of over 258 MW of annual load control available and total energy savings of over 25 GWh (including NEEA) over the 2008 and 2009 calendar periods. A levelized utility cost per saved kilowatt hour of 4.4 cents has been achieved. The levelized avoided costs over the same period were 8.8 cents per kWh. From a conservative UCT perspective, the cost per kW for load management investments was $43.24/kW-yr against the Company's avoided cost of$67.05/kW-yr. Based on program performance, anual reports already filed with the Commission and the analysis provided in Exhibit No. 56, the 2008 and 2009 program costs were prudently incured. Does this conclude your testimony? Yes. Hedman, Supp - 11 Rocky Mountain Power Case No. PAC-E-1O-07 Exhibit No. 56 Witness: Brian K.
