6 Informal questions may be directed to Dave Mosier, Wyoming Regulatory Affairs Manager at (307) Background 4. Rocky Mountain Power was granted authority by the Commission to implement a Wyoming demand-side management program in Docket No EA-06 (the "2006 DSM Docket"). Effective January 1,2009, the Company implemented three residential programs and three commercial/industrial programs in Wyoming based on successful programs previously implemented in the Company's other state jurisdictions. In addition to the Wyoming program availability on January 1, 2009, a customer efficiency rate surcharge was implemented under tariff Schedule 191. On August 3, 2010, the Commission issued an Order in Docket No EA-1O, approving a rate reduction of approximately $330,000 per year related to the Schedule 191 surcharge in order to take into consideration general rate increases approved since the implementation of the demand-side management program in January In addition, the Commission directed Rocky Mountain Power to provide a demand-side management participation improvement plan no later than November 1, The initial Wyoming energy efficiency forecast in the 2006 DSM Docket for calendar year 2009 was approximately 21,000 megawatt hours ("MWh"). Actual Wyoming energy efficiency achieved by the Company in 2009 was approximately 8,000 MWh or approximately 60 percent below the initial forecast. Actual demand-side management program expenditures were 56 percent below the Company's initial projections. In addition, demand-side management expenditures in 2009 were split evenly between the residential and business programs. However, the energy efficiency results 3

7 were not evenly split with residential programs contributing nearly 70 percent of the 2009 energy efficiency savings, which is not unusual as business customer demand-side management projects typically develop more slowly than residential projects due to the lead time required for business customers to complete project studies, develop cost benefit business cases, and incorporate project costs into capital budgets. 6. The 2009 first year results of the demand-side management program in Wyoming are believed to have been impacted primarily by three factors: 1) the economic recession; 2) program ramp time between the approval of the programs and the program availability to Wyoming customers; and 3) general lack of awareness of Wyoming customers regarding DSM programs and associated benefits. 7. The Schedule 191, Customer Efficiency Service Charge, was established with the expectation of providing necessary funding to match the first two years of program activity (calendar years 2009 and 2010). The rate was designed to collect approximately $4.1 million per year and approximately match program expenditures over the two year term. However, due to the less-than-anticipated demand-side management spending, a credit balance has accrued in the Wyoming demand-side management balancing account of approximately $4.3 million as of September 30,2010. Program Modifications 8. Rocky Mountain Power believes its Wyoming DSM portfolio has been successful. The programs generated $1.3 million in net benefits on a Total Resource Cost Basis in 2009, and a Total Resource Cost benefit/cost ratio of This means that the Company's customers realized $1.55 in benefits for each $1.00 spent on demand side resource investments in The 2010 program results (actual results through 4

8 September 2010 plus projections for October through December 2010) are expected to be more than two-and-a-half times greater than those realized in Approximately 21,000 MWh of energy efficiency savings should be realized in 2010 compared to 2009 energy efficiency resource acquisitions of approximately 8,000 MWh. 9. Rocky Mountain Power believes that it is necessary to modify the demand-side management to address changing market conditions. The changes proposed in this Application are designed to improve the energy efficiency acquisition results of the portfolio. Proposed tariffs that include the recommended program changes are included with this Application. In addition, the Company is planning to increase communications in order to improve customer awareness, educate customers on demandside management programs, explain how customers can save energy and promote program participation. 10. The Wyoming demand-side management program expenditures have been less than initially forecasted in the 2006 DSM Docket. The less-than-anticipated spending has led to a credit balance in the Wyoming demand-side management balancing account of approximately $4.3 million as of September 30, Rocky Mountain Power has accrued $103,769 in interest charges through September 30, 2010, associated with the over collections in the DSM balancing accounts. 11. To address the overcollected balances in the three demand-side management balancing accounts, Rocky Mountain Power is proposing to suspend the Schedule 191 surcharge on customer bills effective January 1, This will be accomplished on customer's bills with a continuation of the current "Customer Efficiency Services" surcharge coupled with an additional line item "credit" that exactly off-sets the 5

9 charge. Managing customer billing in this manner maintains transparency of the demand-sid management costs and rate, while avoiding the elimination of the "Customer Efficiency Services" line item on the bill which is how the Company's billing system would treat a zero rate entry. The Company believes that it is more beneficial to suspend the DSM rate surcharge at this time and allow the funds in the balancing account to decline while continuing to provide energy efficiency services to our customers rather than to wait for portfolio expenditures to catch up with Schedule 191 revenues. The time period over which the balancing account funds are returned to customers is projected to vary between 11 to 16 months for each of the three balancing accounts. 12. Rocky Mountain Power will file an application with the Commission in the future as necessary to reinstate each of the three Schedule 191 rate surcharges by eliminating the rate "credit" as the accounts are balanced. Based on the proposed program changes, program expenditures and the increased interest in energy efficiency as demand-side management programs in Wyoming mature, it is entirely possible that when the Company files to remove the credit and reinstate the Schedule 191 surcharges, the rates may be higher than they currently are today. Timing 13. Rocky Mountain Power requests that rate implementation date and suspension of the Schedule 191 surcharge become effective on customer bills on and after January 1,2011. For accuracy in application of the suspension credits, the Company proposes that the suspension credits not be prorated. In addition, the Company recommends that the proposed program changes included in this Application also become effective January 1, However, the Company understands that the 6

10 Commission may not have the opportunity to fully process this Application and render a decision by the January 1, 2011, requested effective date. It is nevertheless important to the Company and its customers, that the suspension of the rate surcharge and the demand-side management program features, particularly those driven by federal code, be implemented at a minimum on an interim basis by January 1, 2011, subject to protest, hearing and further order of the Commission. Conclusion 14. Rocky Mountain Power believes that its demand-side management program in Wyoming is cost effective and beneficial to customers. However, the programs are progressing at a slower pace than initially expected. This has resulted in a build-up in the demand-side management balancing accounts. Rocky Mountain Power believes that suspension of the Schedule 191 rate surcharge requested in this Application is in the public interest. Rocky Mountain Power further believes that changes to the demand-side management programs are in the public interest. 7

11 WHEREFORE, by this Application, Rocky Mountain Power respectfully requests that the Commission: 1. Authorize a suspension of rate Schedule 191 effective January 1, 2011 through an off-setting rate "credit". 2. Authorize modifications to the demand-side management programs as proposed in this Application effective January 1, DATED this 1 st day of November, Respectfully submitted, ROCKY MOUNTAIN POWER Mark C.

101 Docket No _ Witness: Jeffery W. Bumgarner BEFORE THE WYOMING PUBLIC SERVICE COMMISSION ROCKY MOUNTAIN POWER Direct Testimony of Jeffery W. Bumgarner November 2010

102 Q. A. Q. A. Q. A. Q. A. Please state your name, business address, by whom you are employed and your current position. My name is Jeffery W. Bumgarner and my business address is 825 NE Multnomah Boulevard, Suite 600, Portland Oregon, I am the director of demand-side management for Rocky Mountain Power (the "Company" or "RMP"). Please describe your responsibilities as director of demand-side management? My responsibilities include the development of demand-side management ("DSM") program strategy and planning. I work closely with the Company's integrated resource planning ("IRP") department to identify and incorporate DSM resource opportunities into the resource planning process. Identification of DSM resource potential, program planning, introduction of new DSM programs, modifications and terminations of DSM programs all fall within the scope of my responsibilities. Please describe your educational and utility industry background. I received a Bachelor of Science in Finance and Business Management in 1981 from the University of Oregon. Thereafter, I joined PacifiCorp in 1981 in the customer service department and have held various management positions in the customer care, new product and business development and demand-side management departments. I have held my current position since July of What is the purpose of your testimony? The purpose of my testimony is to address the performance of RMP' s Wyoming Page 1 - Direct Testimony of Jeffery W. Bumgarner

103 1 DSM portfolio since its initial offering on January 1, 2009, and to propose 2 measures intended to increase customer awareness of and participation in the 3 programs. I will also propose modifications to the Schedule 191 DSM tariff 4 surcharges to address the current over collections in the DSM balancing accounts. 5 First year performance (calendar year 2009) Q. A. Please summarize the performance of RMP's Wyoming DSM portfolio in 2009 compared to the Company's 2009 forecast provided in Docket No EA -06. Energy efficiency savings acquired through RMP's Wyoming DSM programs in 2009 were approximately 60 percent below the initial forecast in Docket No EA-06 (the "2006 DSM Docket"). Approximately 8,061 megawatt hours ("MWh") of actual energy efficiency was achieved in 2009 in comparison to the nearly 21,000 MWh projected to be achieved. DSM program expenditures were commensurate with program performance in 2009 with actual expenses coming in at approximately 56 percent below the Company's initial projections. DSM expenditures in 2009 were split evenly between the residential and business programs. However, the energy efficiency results were not evenly split, with residential programs contributing nearly 70 percent of the 2009 energy efficiency savings. This is not out of the ordinary as business customer DSM projects typically develop more slowly than residential projects due to the lead time required for business customers to complete project studies, develop cost benefit business cases, incorporate DSM project costs into capital budgets and complete their projects. The table below compares 2009 DSM program results by customer Page 2 - Direct Testimony of Jeffery W. Bumgarner

What were the primary causes associated with not achieving the initial 3 projections for the Wyoming DSM portfolio in 2009? 4 A. As described more fully in Rocky Mountain Power's 2009 Wyoming Demand- 5 Side Management Annual Report ("2009 Annual Report"), filed with the 6 Wyoming Public Service Commission ("Commission") on April 30, 2010, the first year results are believed to have been impacted primarily by three 8 factors: 1) the economic recession; 2) program ramp time between the order 9 approving the programs and the program availability to Wyoming customers; and Page 3 - Direct Testimony of Jeffery W. Bumgarner

105 Q. A. Q. A. Q. A. 3) general lack of awareness of Wyoming customers regarding DSM programs and their associated benefits. What was the most significant factor limiting Wyoming DSM portfolio results in 2009? It's difficult to validate without performing specific market research; however, my professional opinion after having introduced DSM programs in several jurisdictions served by the Company is that a major factor over time is customer awareness. The longer programs are in a market and the more market awareness that is generated, the greater the program participation and results. Considering these factors, has the market for energy efficiency measures and demand-side management programs in Wyoming improved during 2010? Yes. Program results for 2010 (actual results through September 2010 plus projections for October through December 2010) are expected to be two-and-ahalf times those in 2009 with program participation showing significant improvement. The Company attributes this growth to an increase in retailer involvement, business projects with longer lead times reaching completion and a general growth in customer awareness of the Company's demand-side management programs. Has the Company taken action since implementation of the DSM portfolio began to increase program awareness and performance in response to early results? Yes. In addition to program implementation communications, market education efforts, and other planned activities, RMP undertook the following actions to Page 4 - Direct Testimony of Jeffery W. Bumgarner

106 increase participation in the residential programs: worked to secure participation from a larger network of smaller independent appliance retailers (nearly 50 percent of appliance incentives initially came from four retailers in Casper); provided retailers education about compact fluorescent lighting ("CFL") recycling options and assisted stores in getting recycling capabilities in place (to address customer concerns regarding the small amount of mercury found in CFL bulbs and proper disposal); worked to forge closer relationships with appliance retailers to allow customers to have their old refrigerators and freezers picked up for recycling at the same time their new appliance gets delivered (to increase customer convenience and participation); and introduced a CFL distribution measure to the low income weatherization program (Schedule 118) to deliver immediate benefits to these customers as work continued to assist local community action agencies in delivering a broader energy efficiency program and services. To improve business customer participation in DSM programs, RMP implemented the following actions: coordinated with Questar Gas Company in the launch of its Wyoming DSM programs in July 2009, emphasizing the availability of incentives for both electric and natural gas equipment; conducted a broad review of the heating, ventilation and air conditioning equipment distributors serving Wyoming and provided them with Page 5 - Direct Testimony of Jeffery W. Bumgarner

107 Q. A. Q. A. information about the programs and availability of incentives for high efficiency equipment; and referred eligible customers to engmeenng resources to identify sitespecific projects that may be eligible for Self-Direction Credit program (Schedule 192) incentives. A more comprehensive review of actions taken in 2009 to improve the portfolio's performance can be found in the 2009 Annual Report. Despite slower than anticipated initial program growth, do you expect the DSM portfolio to eventually achieve the energy efficiency savings projected in the 2006 DSM Docket? Yes. While the market's reaction in Wyoming has resulted in slower portfolio growth than was initially anticipated, the Company remains confident that the initial projections are achievable. As the programs are allowed to mature in the market and Wyoming customers become more aware of the existence and benefits of DSM programs, coupled with program modifications intended to improve portfolio performance and, of course, an anticipated improvement in the nation's economy, I expect participation to reach the levels initially forecast, albeit later than initially projected. What provides you this confidence? RMP has recently commissioned a refresh of the 2007 demand-side management potential study, which assessed DSM resource potential throughout the Company's service territory. Although the results are preliminary, initial study results suggest Wyoming's energy efficiency resource opportunities are equal to Page 6 - Direct Testimony of Jeffery W. Bumgarner

108 1 or greater than originally identified in the 2007 study. As the Company continues 2 to refine the identification of these resource opportunities and develops plans and 3 programs to capture them, portfolio performance should continue to improve. 4 Q. Why should RMP's Wyoming customers have an interest in the pursuit of 5 DSM resource opportunities? 6 A. Wyoming customers should be interested in the pursuit of cost effective DSM as 7 it helps the Company reduce the costs of providing electric service to our 8 customers. Net-power costs account for roughly 30 percent of Wyoming's 9 revenue requirement. DSM resources on average cost $0.034 per kilowatt hour 10 ("kwh,,)l compared to the average cost of new generation resources at $0.07 per 11 kwh and up? DSM resources are a least cost resource alternative to new 12 generation and where cost-conscious utilities focus first in meeting their customer 13 energy demand requirements. Customers should encourage utilities to acquire as 14 much cost-effective DSM resources as possible, especially in markets such as 15 Wyoming where average load growth is forecasted to exceed other RMP services 16 territories at 3.6 percent annually according to the Company's 2008 IRP Update. 17 The resources saved through energy efficiency programs benefit both program 18 participants and non-participants alike through lower system costs to RMP in 19 meeting customer electricity requirements. These lower costs translate into lower 20 retail pricing over time than would otherwise occur without energy efficiency. 1 Refer to Table 1 on page 3 of the 2009 Annual Report. 2 Refer to the 2008 Integrated Resource Plan Update - March 31, 2010 "2008 IRP Update" Page 7 - Direct Testimony of Jeffery W. Bumgarner

109 1 2 3 Q. Should the fact that 2009 results fell short of the forecast be interpreted in any way to mean the Wyoming DSM portfolio is not providing benefits to RMP's Wyoming customers? 4 A. Not at all. As noted in the 2009 Annual Report, first year DSM energy savings 5 were 8,061 MWh. In terms of value, the resulting savings generated $1.3 million 6 in net benefits on a Total Resource Cost Basis in Net benefits represent the 7 difference between the lifetime benefits of the energy efficiency savings acquired 8 and the total costs incurred to acquire the savings. In the most basic terms, the 9 portfolio Total Resource Cost ratio of means that the Company's 10 customers realized $1.55 in benefits for each $1.00 spent on Wyoming demand- 11 side resource investments in Second year performance to date (calendar year 2010) 13 Q A Is the performance of the Wyoming DSM portfolio in 2010 showing improvement over the results achieved in 2009? Yes. As mentioned earlier in my testimony, the 2010 program results (actual results through September 2010 plus projections for October through December 2010) are expected to be more than two-and-a-half times greater than those realized in Approximately 21,000 MWh of energy efficiency savings should be realized in 2010 compared to 2009 energy efficiency resource acquisitions of 8,061 MWh. 3 Refer to Table 23 in the 2009 Annual Report. Page 8 - Direct Testimony of Jeffery W. Bumgarner

110 Q. A. Q. A. Q. A. Is this in alignment with the Company's initial projections for 2010 provided in the 2006 DSM Docket? No. The 2010 portfolio results are expected to align more closely with the Company's initial 2009 program forecast. In 2010, the Company expects to acquire approximately 21,000 MWh of energy efficiency resources compared to the initial 2009 forecast of 20,800 MWh. This indicates that market adoption of the Company's DSM programs in Wyoming has been slower than anticipated, but nevertheless is showing positive signs of growth. Does the Company expect that initial forecasts in the 2006 DSM Docket for program years 2011, 2012 and 2013 forecasts will be met? No. The 2009 and 2010 actual program results along with the Company's revised forecast suggests that program performance will be roughly 50 percent of the Company's initial five year projection. Exhibit RMP_(JWB-1) provides an analysis comparing the Company's initial portfolio forecast in the 2006 DSM Docket to the Company's revised forecast, which is based on 2010 market performance and current assumptions. Despite the Wyoming DSM portfolio falling short of meeting the Company's initial projections, does RMP consider the portfolio to be successful and if so, under what performance standard? Yes, Rocky Mountain Power believes its Wyoming DSM portfolio has been successful. As Company witness Ms. Carol L. Hunter stated in direct testimony in the 2006 DSM Docket in response to Commissioner Byrnes' first Special Opinion issue regarding performance standards, "The Company proposes to base success Page 9 - Direct Testimony of Jeffery W. Bumgarner

111 Q. A. of the amended DSM application on a cost-effectiveness standard rather than a specific resource acquisition target." As demonstrated in Table 1 on page 3 of the Company's 2009 Annual Report, the first year energy savings for 2009 achieved through the Wyoming DSM portfolio was 8,061 MWh. The portfolio generated $1.3 million in net benefits on a Total Resource Cost Basis in 2009 and achieved a Total Resource Cost benefit/cost ratio of As previously explained, this means that the Company's customers realized $1.55 in benefits for each $1.00 spent on demand side resource investments in Why did the Company propose in the 2006 DSM Docket that DSM portfolio success be measured on a cost-effectiveness standard rather than a specific resource acquisition target basis? Ms. Hunter testified in the 2006 DSM Docket that the rationale is two-fold: "First, specific DSM targets are difficult to manage simply due to the voluntary nature of the DSM measures and the uncertainty of customer participation. Unlike market purchases or plant construction, DSM resources acquisitions require customer participation. The Company can influence customer participation through building program awareness and offering well designed programs; however, the Company cannot control it. The incentive provided is designed to influence customers' energy decisions, not to completely compensate customers for their investments. Second, DSM targets can result in bad DSM policy because setting specific goals may result in regulatory and Company decisions or actions that are not efficient or least cost based and made solely to achieve the target goal. 4 Refer to Table 23 in the 2009 Annual Report. Page 10 - Direct Testimony of Jeffery W. Bumgarner

112 Q. A. Q. A. Using a cost-effectiveness standard to measure success ensures that the Company is pursuing least cost resources and will do so only to the extent they benefit the Company and Wyoming customers." Has the Company completed the program evaluations as outlined in your Exhibit RMP _.12(JWB-12) in the 2006 DSM Docket? The Company has completed an initial cost-effectiveness assessment and provided the results of that assessment in the 2009 Annual Report. The Company has not completed program impact and process evaluations which were scheduled for completion 22 months following the implementation of the DSM portfolio. Why were the impact and process evaluations not completed as scheduled? The impact and process evaluations were planned for the 2009 program performance period. With the exception of the low income weatherization and FinAnswer Express programs, overall portfolio performance in 2009 was less than expected (in terms of total savings and number of participating customers) and was insufficient to produce results commensurate with the cost of the evaluations. The Company instead will bundle the 2009 and 2010 program results and complete impact and process evaluations on the combined results, with draft final evaluation reports projected to be available by October Proposed program changes 20 Q. 21 A Is RMP proposing revisions to its Wyoming DSM programs at this time? Yes. While the Wyoming portfolio has shown improvement since its inception in early 2009, the Company recommends program modifications to address changing market conditions. The changes are designed to grow and improve the Page 11 - Direct Testimony of Jeffery W. Bumgarner

113 1 energy efficiency acquisition results of the portfolio. Some of the proposals are 2 naturally evolving programmatic changes which are being implemented in the 3 Company's DSM portfolios in its other jurisdictions, while others are specific to 4 Wyoming in recognition of the unique delivery challenges discovered since the 5 portfolio's introduction in In total, Rocky Mountain Power is proposing 6 modifications to all six of its Wyoming DSM programs. In addition, the Company 7 intends to increase program customer communication activity with the objective 8 of increasing customer awareness of and participation in the Wyoming DSM 9 programs. 10 Q. Please provide a summary of the DSM program modifications you are 11 proposing. 12 A. The table below provides a high level summary of the DSM program changes the 13 Company is proposing.

A. Has the Company collected more funds through the Schedule 191 DSM surcharge than has been expended on energy efficiency investments to date? Yes. The longer lead time in program adoption has led to correspondingly fewer 10 program expenditures than initially forecasted. Schedule 191, Customer Q. A. Efficiency Service Charge, was established with the expectation of providing the necessary funding to match the first two years of program activity, which is a typical practice with new DSM programs to ensure rate stability during the initial portfolio implementation. The less-than-anticipated DSM spending has led to a credit balance in the Wyoming DSM balancing account of $4.3 million as of September 30, Exhibit RMP_UWB-4) provides additional detail on the status of each balancing account by customer category. Are Wyoming customers being compensated for the over collection of Schedule 191 revenues? Yes. Schedule 191 was designed to include reciprocal interest charges at the current Customer Deposit Rate (as shown in Schedule 300) which is applied to over or under collections, a common situation that can occur during initial program implementation or during periods of significant market activity not Page 15 - Direct Testimony of Jeffery W. Bumgarner

117 Q. A. Q. A. anticipated between collection rate adjustments. This design encourages the Company to prudently manage the Schedule 191 collection rate and the funds in the three DSM balancing accounts. Through September 30, 2010, Rocky Mountain Power has accrued $103,769 in interest associated with the over collections in the DSM balancing accounts. Exhibit RMP_UWB-4) provides the account balances and interest associated with these over-collections. Is Rocky Mountain Power recommending an adjustment to the Schedule 191 collection rates at this time to address the over collected balances in the DSM balancing accounts? Yes. To address the over collected balances in the DSM balancing accounts, Rocky Mountain Power is proposing to implement a credit equal to the Schedule 191 surcharge on customer bills effective January 1, The effect of this credit will be to suspend the Schedule 191 surcharge on customer bills. In light of actual program performance and spending to date, the Company believes it is more beneficial to suspend the Schedule 191 surcharge on customer bills at this time and allow the funds in the balancing accounts to decline while the Company continues to offer demand-side management programs to our customers rather than wait for portfolio expenditures to catch up with Schedule 191 revenues. How does the Company propose handling the temporary suspension of Schedule 191 charges on customer bills? The Company proposes to leave the Schedule 191 "charge", currently described as "Customer Efficiency Services" on customer bills and add a second line item "credit" to the bill which carries a similar description while clearly identifying the Page 16 - Direct Testimony of Jeffery W. Bumgarner

118 Q. A. credit. A bill message will also be added to Wyoming customer statements further explaining the credit and informing customers that DSM programs will remain available during the suspension period. There are two primary reasons the Company is proposing this approach: 1) The Company's billing system will entirely eliminate the line item "Customer Efficiency Services" charge on customer bills if the rate surcharge is reduced to zero. There must be a non-zero rate in order to retain the "Customer Efficiency Services" line item charge on the bill; 2) The Company is concerned that if the "Customer Efficiency Services" charge on the bill is eliminated, customers will lose connection with the Company's DSM portfolio and the related costs. Additionally, when the DSM balancing accounts become aligned with expenditures and the rate surcharge needs to be re-established, going from a zero rate to a positive rate will have the appearance of a rate increase to customers. Rocky Mountain Power believes managing the billing issue by continuing to show the current surcharge rate coupled with an off-setting credit, will maintain transparency without creating potential billing and price signal issues as discussed above. How long does RMP anticipate that Schedule 191 charges will be suspended before the funds in the balancing accounts are depleted? The time period over which the funds are depleted is projected to vary for each of the three balancing accounts; however, based on the Company's revised Wyoming DSM portfolio forecast, the Company expects that depletion of the funds will require the Schedule 191 charges to be suspended for a period of 11 to 16 months. Exhibit RMP_(JWB-5) provides the Company's analysis in support Page 17 - Direct Testimony of Jeffery W. Bumgarner

119 Q. A. Q. A. of these estimates for each of the three balancing accounts. The Company will file an application in the future when appropriateto eliminate the credit and reinstate the Schedule 191 charges as the balancing accounts approach a balanced position. When RMP eventually files an application to eliminate the rate credit and reinstate the Schedule 191 surcharge, is it possible for the rate to be different than it currently is? Yes. Due to increased customer awareness and program expenditures anticipated by the proposed program changes, it is entirely possible that when RMP files to eliminate the Schedule 191 credit the rates may be higher than they currently are. How does the Company propose handling the issuance of Schedule 192 Self Direction Credit program incentive bill credits during the suspension period? The Company is proposing no change to the current issuance of Self-Direction Credit program incentives to qualifying customers. Those qualified to receive their program incentives over time will receive three line items on their monthly bill: 1) a charge equal to their approved Schedule 191 charge; 2) a credit representing the suspension of the charge; and, 3) a Self-Direction credit equal to the above noted charge (number 1 above). As no new revenues will be collected during the suspension period, the Self Direction Credit incentives paid during this time will be handled as a debit against the over-collection of revenues (balancing account balances) until those revenues are exhausted. Page 18 - Direct Testimony of Jeffery W. Bumgarner

120 1 Q. 2 3 A Q. 15 A. What effective date is RMP proposing for the program modifications and the suspension of the Schedule 191 surcharge? The rate implementation date (suspension of the Schedule 191 surcharge) is requested to be effective on bills rendered on and after January 1, For accuracy in application of the suspension credits, the Company proposes that the suspension credits not be prorated. In addition, the program changes are also requested to be effective January 1, However, the Company understands that the Commission may not have the opportunity to fully process this Application and render a decision by January 1,2011. It is nevertheless important to the Company and our customers, that the suspension of the rate surcharge and the program features driven by federal code be implemented at a minimum on an interim basis by January 1, 2011, subject to protest, hearing and further order of the Commission. Does this conclude your testimony? Yes. Page 19 - Direct Testimony of Jeffery W. Bumgarner

126 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 1 of 41 Docket No Witness: Jeffery W. Bumgarner Exhibit RMP_(JWB-2) This exhibit provides background information on each of Rocky Mountain Power's Wyoming demand-side management programs and additional detail on changes the Company is recommending to make to those programs. Information will be provided on the six following programs: Residential Programs Schedule Low Income Weatherization program Schedule Refrigerator/Freezer Recycling Schedule Home Energy Savings Incentive, Business Programs Schedule FinAnswer Express Schedule Energy FinAnswer Schedule Self-Direction Credit Page 1 Page 3 Page 4 Page 25 Page 39 Page 41 Proposed changes to Residential Programs Low Income Weatherization Program - Schedule 118 Background The Low Income Weatherization Program is designed to provide demand-side management services to income eligible residential customers. The Company has partnerships in place with the Wyoming Energy Council and the Council of Community Services to provide weatherization services. These two non-profit agencies receive federal and state grants as well as Company funding. Participants can be homeowners or renters and reside in single-family homes, manufactured homes or apartments and receive the energy efficiency services at no cost. This program was approved to be offered on or after January 1, 2009 however agency agreements were not completed and major measure made available until May, The Company filed to revise the Low Income Weatherization program tariff, Schedule 118 on December 12, 2008 through Docket No ET-08. In the December 12 filing the Company proposed to add a provision allowing for the direct distribution of energy saving measures within the tariff. An order was issued by the Wyoming Public Service Commission on February 2, 2009 approving direct distribution. Working with the Wyoming Department of Family Services the Company obtained a list of customers that received Low Income Energy Assistance Program (LIEAP) funds and began distributing compact fluorescent bulb kits to LIEAP recipients. We estimate annual savings of 232 kwh per kit which provides annual bill savings of approximately $ Page 1 of 41

127 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 2 of 41 Docket No Witness: Jeffery W. Bumgarner Description of Planned Low Income Weatherization Program Changes As authorized in the revised Schedule 118, PacifiCorp will, if it is determined to be cost effective, expand the delivery of supplemental program measures. The company is currently planning to provide Energy Star qualified refrigerators, collecting and recycling older inefficient models in accordance with EPA disposal guidelines. The direct delivery of the refrigerator replacement measures will be achieved through a competitive bid process and serve to complement the objective of the program; to reduce the electricity requirements and increase the penetration of weatherization and efficiency measures in residential dwellings inhabited by low income households. The final determination regarding the proposal will be based on costeffectiveness, which will be assessed upon receiving vendor delivery bids through the competitive bid process. The refrigerator replacement offering is expected to be available no later than the third quarter of Refrigerators were selected because they are one of the highest electricity users in a home. Generally only space heating and cooling and water heating use a greater amount of electricity in homes. There is an opportunity to obtain large kilowatt hour ("kwh") savings by replacing inefficient refrigerators with Energy Star certified models. And as a result of federal guidelines on the average amount that can be invested per home, most homes served by weatherizing agencies are not receiving a refrigerator even if it is found to be cost effective. Shell measures that increase space heating and cooling efficiencies are generally completed first often leaving insufficient funds for refrigerator replacements. In addition, not all homes heat with electricity or have electric water heaters so the direct distribution of refrigerators within the low income weatherization program will make benefits available to a larger number of our Rocky Mountain Power Wyoming customers. The Company estimates that approximately 13,000 Rocky Mountain Power customers received LIEAP assistance in Energy Information Administration data indicates that between 7 percent and 29 percent of people eligible for federal energy assistance have refrigerators older than 18 years old, which the Weatherization Assistance Program Technical Assistance Center uses as a cutoff for qualifying for a replacement. Assuming a mean percent of 18 percent that would suggest approximately 2,340 of Rocky Mountain's income qualifying Wyoming customers would be eligible for a replacement refrigerator. The Company will limit the number of replacements annually to manage within the budget established for the low income weatherization program. This limit will be determined based on a number of factors including the vendor delivery costs to be determined through the competitive bid process, compact fluorescent bulb kit distribution costs, and agency weatherization or major measure activity and related costs. The Company proposes mailing details regarding the refrigerator replacement offer to Rocky Mountain Power customers that received LIEAP assistance in the past LIEAP program year. The mailing will include a reply card in which customers will be asked to record the model number from their refrigerator if they are interested in participating. Those customers that Page 2 of41 2

128 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 3 of 41 Docket No Witness: Jeffery W. Bumgarner respond with qualifying equipment will be screened further to ensure their equipment qualifies for replacement and will be provided a new refrigerator on an first come first serve basis while funding is available in that year. Interested income eligible customers will benefit from the installation of a new refrigerator as many old models use a large amount of electricity. The Company's analysis indicates that the average annual savings will be approximately 1,200 kwh, which provides bill savings of about $ per year. The Company is proposing refrigerator replacements be available to both home owners and renters. The intent of the Low Income Weatherization program is to help customers become more energy efficient whether they rent or own their home. Refrigerator replacements are available through the Wyoming Family Services Department low income weatherization funding to home owners and renters also. Permission to replace a refrigerator will be required by the refrigerator owner through a signature, which in some cases will be a landlord. No program tariff changes are required to implement the direct distribution of refrigerators through the program, the current guidelines within Schedule 118 provide the necessary authority and guidelines under which the offer will be designed and offered. RefrigeratorlFreezer Recycling - Schedule 117 Background The refrigerator recycling program, which is marketed as "See ya later, refrigerator '\ is available to residential customers through a Company contract with a third-party program administrator, JACO Environmental Services. Older refrigerators and freezers which are less efficient, yet operational, are taken out of use permanently and recycled in an environmentally responsible manner. The program's objective is to permanently retire these older and less efficient refrigerators and freezers from the market and recycle the units in order to avoid their re-entry or resale on the secondary appliance market. To participate, customers call a number to schedule a pick-up of their refrigerator or freezer. Program awareness is generated through mass media advertising channels as well as Company channel communications such as the program's Web site, bill inserts, and customer newsletters. In addition to free pick-up of their appliance and a cash incentive of $30, participants receive an energy efficiency packet consisting of ENERGY STAR -certified compact fluorescent light bulbs, a refrigerator/freezer thermometer, and energy education materials. This program was first offered to Wyoming customers January 1,2009. Description of Planned RefrigeratorlFreezer Recycling Program Changes In 2010 the Company began working to forge relationships with appliance retailers to allow customers purchasing new units to have their old appliance picked up at the time their new appliance was being delivered. In addition, the Company is proposing to increase the cash incentive paid to customers for their participation from $30 to $40, further increase program advertising, and re-evaluate the contents in the energy efficiency packet to look for greater instant savings value for participating customers. Page 3 of 41 3

129 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 4 of 41 Docket No Witness: Jeffery W. Bumgarner When the program was first introduced in Rocky Mountain Power's other jurisdictions, the cash incentive was $40 and later reduced to $30 once the program was well established and program awareness achieved. The Company feels that with the prolonged economic recession and resulting customer behavior increasing the cash incentive will encourage greater customer participation. In addition to increasing the participation cash incentive, the Company proposes further increases to the program advertising as a means of not only increasing participation in the "See ya later, refrigerator ~~ program but the overall demand side management program and offerings. The "See ya later, refrigerator ~~ program is a highly visible and recognizable program, and participants in the program receive information on Rocky Mountain Power's other programs such as the Home Energy Saving program as well as receive general tips on how to be wattsmart. Participants currently receive a free energy-saving packet or kit, which includes two compact fluorescent light bulbs (CFLs), a refrigerator/freezer thermometer card, an energy-savings brochure and information on other energy saving residential programs and resources. The Company is investigating complementing this kit with additional instant savings measures to maximize customer value and savings. Examples might include the addition of a low flow showerhead and faucet aerators for electric water heating participants and a coupon for a free third CFL directing customers to local retailers participating in the Home Energy Saving program's CFL buy-down program. Final determination regarding the addition of measures will be based on the overall cost-effectiveness of the program with the inclusion of the measures. A tariff change will be required to increase the cash incentive however the other program changes are currently authorized under Schedule 117 as currently approved. Home Energy Savings Incentive - Schedule 111 Background The Home Energy Savings program provides a broad framework to deliver incentives for more efficient products and services installed or received by Wyoming customers in new or existing homes, multi-family housing units or manufactured homes. The program is delivered through a third party administrator hired by the Company. Qualifying equipment descriptions, customer and dealer incentives, dates of incentive availability and reference to additional program or contractor requirements are included in the tariff. Additional information on measure specific requirements applicable to customers or contractors is provided on the program web site in addition to incentive applications. Eligible program measures include: washing machines, refrigerators, water heaters, dishwashers, lighting (both compact florescent lamps (CFLs) and fixtures), cooling equipment and services, ceiling, wall and attic insulation, windows and miscellaneous equipment such as ceiling fans. Incentives are provided to customers through two methods: (1) post-purchase application process Page 4 of41 4

130 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 5 of 41 Docket No Witness: Jeffery W. Bumgarner with incentives paid directly to participating customers, and (2) incentives paid to mid-market retailers and manufacturers for buy-downs for delivery of CFLs. Mid-market buy-downs result in lower retail prices for customers at the point-of-purchase and involve no direct customer application process. In the second quarter of 2010, the company's third party program administrator examined Wyoming customer participation data, changes in sales volumes and third party standards, information from the program in other markets and other similar programs to identify possible changes to the Home Energy Savings program. The primary objective of this analysis is to increase customer participation and the level of cost-effective electrical energy savings realized by the programs. Description of Planned Home Energy Savings Incentive Program Changes As a result of this work, new equipment categories, new measures, changes in eligibility requirements and incentive levels are proposed for the program. The changes are designed to increase participation, savings acquisition and improve the comprehensiveness of the program for customers and trade allies. The changes are outlined in the table below. Changes described below include existing measures where incentives or eligibility criteria are proposed to change or if new measures are being proposed as additions to the program. Changes to unit savings, measure life or measure life assumptions for existing measures are not described below, but are included in the cost effective analysis provided in Exhibit RMP _ (JWB-3). Measure Category Appliances Description of Change Modify eligibility requirements and incentive level for an existing measure: Clothes Washers Combine the current Modified Energy Factor (MEF) tiers used to qualify eligible equipment into a single tier. Increase minimum MEF for the single tier to Provide a $50 Reason for Change Customer purchases of qualifying washing machines increased in 2010 by more than 125% (when compared with 2009) and the availability of energy efficient dishwashers in Wyoming has increased substantially. These factors can be attributed to greater program awareness during 2010 combined with additional incentives provided by ARRA. In addition, the federal standards and ENERGY STAR change scheduled for January 2011 all serve to increase average washing machine efficiency. These efficiency level changes indicated it was appropriate to mcrease the baseline equipment efficiency assumption from l.26 to l.9 Modified Energy Factor (MEF) and propose a higher MEF necessary to qualify for incentives. This proposed change in equipment eligibility helps move customers to the higher tier and ensures the available incentive remains aligned with the energy savings. Energy savings will continue to be reported based on individual participant water heating and dryer fuel source information Page 5 of41 5

131 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 6 of 41 Docket No Witness: Jeffery W. Bumgarner Measure Category Description of Change incentive for machines meting this qualification. Modify eligibility requirements for an existing measure: Dishwasher Align eligibility requirements with Consortium for Energy Efficiency (CEE) Tier 2 instead of ENERGY STAR. Modify eligibility requirements and incentive level for an existing measure: Electric Water Heaters Specify different EF depending on tank sizes for eligibility. Adjust the incentive from $50 to $75 per tank. Reason for Change provided on the incentive application. Customer purchases of qualifying dishwashers increased in 2010 by more than 200% (when compared with 2009) and the availability of energy efficient dishwashers in Wyoming has increased substantially. These factors can be attributed to greater program awareness during 2010 combined with additional incentives provided by ARRA. Federal standards changed m 2010 have required the baseline equipment to become more efficient. ENERGY STAR standards will change in January 2011 in response to these increased federal standards. The federal standards changes have reduced the energy savings available from each dishwasher meeting the current and new ENERGY STAR requirements. In order to ensure a minimum level of savmgs to align with the current $20 incentive, the eligibility requirements need to be increased. CEE develops and maintains standards for some appliances and in some cases have standards that exceed ENEGY STAR. This is the case with the CEE Tier 2 requirements for dishwashers which is why the standard was selected to replace the ENERGY STAR standards for dishwashers in the program. Research by the program administrator indicates product meeting these requirements IS available m Wyoming. Energy savings will continue to be reported based on individual participant water heating fuel source and efficiency levels from information provided on the incentive application. Customer participation in the current offer has remained relatively flat despite previous outreach efforts and eligible equipment availability remains limited. Under the current qualifications, larger tank sizes rarely meet the current qualifications which requires an Energy Factor (EF) of 0.93 or greater and provides a $50 incentive for all tank sizes, 40 gallons and larger. The proposed change is to require different EFs for different tank sizes and increase the incentive from $50 to $75 for all tank sizes. Since electric water heating is less prevalent than gas in Wyoming, it is important that the program offer be as comprehensive as possible to help ensure that high efficiency equipment IS purchased instead of baseline equipment when tanks are replaced, typically when existing tanks fail or for new installations. The EF will be different based on the tank size. Page 60f41 6

132 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 7 of 41 Docket No Witness: Jeffery W. Bumgarner Measure Category Description of Change Add new measure: Heat Pump Water Heater Provide customer and contractor incentives for ENERGY STAR qualified units. $150 to customer $100 to contractor Reason for Change gallon with EF of 0.93 or greater gallon with EF of 0.91 or greater 66 + gallon with EF of 0.89 or greater The Wyoming American Recovery and Reinvestment Act (ARRA) Appliance Rebate Program substantially increased awareness of this technology by offering incentives for it. The federal code is scheduled to change in April 2015 for electric water heaters and models with a storage capacity greater than 55 gallons must be a heat pump water heater. The combination of ARRA activity and the established date for the code change has served to increase contractor and retailer requests for incentives for the measure. While current retailer stocking practices are predominantly special order, there are at least 15 retailers carrying models from GE, Rheum, and Richmond. Retailers include Menard's (Casper), Neilson's (Kemmerer), Rushmore (Rock Springs) in addition to Sears, Home Depot and Lowe's. Heat pump water heaters utilize the same technology that is used to heat and cool homes by extracting heat present in the air and transferring it to water in a tank. Fans pull in warm air from the space around the unit, and pass it over an evaporator where it is transferred to the water via an electrically powered refrigeration compressor and refrigerant loop. Hot water is stored in an insulated tank similar to standard electric water heater. These units also have conventional heating elements to boost the temperature and production of hot water should there be additional demand. There are several differences between heat pump and standard electric water heaters installations and for these reasons contractor installation IS required. Differences include: discharge of cool, dry air into the surrounding space, compressor and fan noise, the need to regularly service the evaporator fan filter, ensuring that the units are installed in a space with the minimum of 1,000 cubic feet of air, and that the units operate most efficiently when the ambient air is above 40 (below 40 the system switches automatically to a standard electric water heating mode) and the slightly larger size when compared to standard electric water heaters. The program recommends offering an incentive of $150 for customers and an incentive of $1 00 for contractors. The heat pump water heater must be ENERGY STAR qualified. The Page 70f41 7

133 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 8 of 41 Docket No Witness: Jeffery W. Bumgarner Measure Category Description of Change Add a new measure Clothes Washer Recycling $50 incentive to the retailer. Eligibility is tied to machines removed from Rocky Mountain Power customers who purchase an eligible high efficiency washing machine. Reason for Change program will require additional documentation for verification including a photo of the installation for verification. All installations are subject to on-site inspections for quality assurance purposes. Currently, many retailers offer to remove the old appliance when they deliver a new one and typically they sell these machines in "lots" to used appliance vendors. By providing this incentive to retailers, it reduces the number of machines and parts that enter the secondary market. It will only be available to retailers who sell a qualifying washing machine to an eligible Rocky Mountain Power customer. Consumer Electronics Add a new measure Freezer Provide a $20 incentive for ENERGY STAR qualified unit. Add new measure category and measures: Flat Panel TV s Flat panel televisions required to meet ENERGY STAR v 5.1 standard. Provide a $50 incentive for ENERGY STAR 5.1. Customer demand for ENERGY STAR appliances has increased in Wyoming which is partially attributable to ARRA funding and program incentives for appliances. Adding this measure has the potential to generate additional energy savings and responds to a Wyoming specific need where rural customers tend to have the need for more food storage. Adding this measure mcreases the comprehensiveness of the program for customers and retailers. According to the Energy Information Administration Report #:DOEIEIA-0383(2010), home electronics is expected to represent nearly 50% of home electricity use by 2035, more than appliances and lighting combined. According to Northwest Energy Efficiency Alliance (NEEA) which coordinates delivery of a regional home electronics program m the Northwest which includes incentives for flat panel televisions, approximately 70% of flat panel televisions meet the requirements of ENERGY STAR v. 4.l, while only 8% are rated ENERGY STAR v Utilizing the ENERGY STAR v. 5.1 standard as the eligibility requirement will provide a minimum level of savings per unit in a market that is evolving rapidly. Many manufacturers are meeting the ENERGY STAR v. 4.1 Page 80f41 8

134 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 9 of 41 Docket No Witness: Jeffery W. Bumgarner Measure Category Description of Change Reason for Change specifications, but there are few manufactures who currently meet the ENERGY STAR v. 5.1 standard. The current market place has limited v 5.1 availability, but there are products at Wyoming retailers that meet this specification. Flat panel televisions have an average life expectancy of 6 years. The average yearly savings is 179 kwh/unit Provide $50 incentive to customers for the energy efficient models meeting the requirement of ENERGY STAR v The qualification will float with the ENERGY STAR when the new version becomes available. The qualified product list will be provided on the program website. Incentives will be paid after a post purchase application submitted by the customer is approved by the program administrator. Add new measure category and measures: Computer Monitors Monitors required to meet ENERGY STAR v 5.0 standard. According to a Global Industry Analyst report liquid crystal display (LCD) monitor sales represent 70% of the market for monitors. This shift away from cathode ray tube (CRT) monitors has brought on a new ENERGY STAR specifications for LCD monitors. Nationally, the current ENERGY STAR v. 5.0 monitors represent 47% of the overall monitor market with rural markets having lower market shares. ENERGY STAR current schedules calls for review and Customer incentive $5 revisions to the current v. 5.0 standard on October 30,2011. LCD monitors are the most common monitors. However, other technologies exist and are ENERGY STAR qualified. These other technologies include plasma, cold cathode fluorescent lamps (CCFL), and light-emitting diode (LED) with LED being the most energy efficient. EMERGY STAR monitors have an average life expectancy of 5 years and gross annual energy savings of 14 kwh over non-energy STAR models. Provide $5 incentive to customers for energy efficient models meeting requirement of ENERGY STAR v The qualification will float with the ENERGY STAR when the new version becomes available. The qualified product list will be provided on the program website. Incentives will be paid after a post purchase application submitted by the customer is approved by the program administrator. Add new measure The top 5 manufacturers of computers account for over 78% Page 9 of41 9

135 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 10 of 41 Docket No Witness: Jeffery W. Bumgarner Measure Category Weatherization Description of Change category and measures: Desktop Computers Desktop computers meeting the ENERGY STAR v 5.0 Customer incentive $10 Modify eligibility requirements and incentive levels for an existing measure: Retrofit Insulation Adjust the current incentive levels for adding insulation to each area (ceiling, wall floor) of an existing home. Provide different incentive levels for each area depending on heating and cooling equipment and fuel source. Reason for Change of the sales of computers in the United States. They only make up 20% of the qualified models on the ENERGY STAR list. This means most consumers are not purchasing new high efficiency desktop computers. ENERGY STAR desktops represent 20% of available models in the Wyoming market. Current ENERGY STAR v. 5.0 for desktop computers was effective July Desktop computers are reviewed and tested under 4 categories depending on processor type and the amount of system memory. The savings are calculated as an equation that includes power use during off, sleep, and idle modes. Provide $10 incentive to customers for the energy efficient models meeting requirement of ENERGY STAR v The qualification will float with the ENERGY STAR when the new version becomes available. The qualified product list will be provided on the program website. Incentives will be paid after a post purchase application submitted by the customer is approved by the program administrator. During the original design, several measures, including insulation utilized savings values derived from Regional Technical Forum (RTF) data. RTF data was chosen based on prior weatherization studies that had been completed in the Northwest. RTF does not have explicit cooling load savings calculations since the Northwest is typically heating dominated. To develop an estimate of cooling savings and account for the gas/electric heat split in Wyoming, the RTF estimates were used in conjunction with heating and cooling degree day data to arrive at the per square foot deemed savmgs values. These numbers had the advantage of simplicity for program administration and were appropriate since Wyoming specific data was not readily available. As Wyoming housing stock information became available through information contained in incentive applications, the Company and program administrator recognized the need to generate better savings estimates, specific to the Wyoming climate and recommended the use of a simulation model in place of the pnor estimates. Simulation models are computer based models which allow energy analysts to provide input information on variables such as age of housing stock, average insulation levels, building size and configuration, cooling and heating plant efficiencies, climate Page 10 of 41 10

Bumgarner Measure Category Description of Change Reason for Change zone, etc. Energy Gauge modeling software was selected as it is widely used in the industry, and is supported by DOE. Inputs to Energy Gauge were based on application data to date and professional judgment for such factors as cooling system efficiency, baseline windows, duct placement, etc. Adjustments and recommendations for each of the three areas as well as an added "spiff' are described below. Attic Insulation Adjust $0.35/SF incentive for attic insulations to: $0.15/SF - electrically cooled homes $0.50/SF - electrically heated homes Currently $0.35 per square foot incentives for attic insulation are available with the requirement of pre-existing R-18 or less and minimum installation ofr-19 or greater for both electrically heated homes and electrically cooled homes. However the savings per square foot results from the recent simulation as described above indicates a wide variation between savings available from electrically heated and electrically cooled (i.e., gas heated) homes; (0.15kWh/SF for electrically cooled homes compared to 2.91 kwh/sf for electrically heated homes). To Improve the alignment of incentive amounts with estimated savmgs available, the recommendation IS to provide a $0.50 per square foot to the electrically heated home and $0.15 per square foot to the electrically cooled homes. The $0.15/sf is limited by the amount the program can afford to pay for the electric energy savings estimated to be available on a per square foot basis. To better align with current market practices and the trend in other programs with weatherization offers to require a substantial amount of added insulation to help prevent multiple treatments of the same space, the mmimum requirement for added insulation levels will move from R- 19 to R-30. The final insulation levels must be R-49 or greater. The pre-existing insulation requirements will be adjusted slightly to R - 20 or less Market data indicates the average cost of installed insulation (blown in cellulose) is about $0.7 4/sf and the electrically heated home incentive is designed to offset about two thirds of the costs. For some gas heated homes, gas company incentives are available from Questar which add another $0.20/Sf and the resulting combination covers about 47% of the average costs. The remaining costs are recovered by the homeowner over time through reduced usage and bill savings. Page 11 of 41 11

However the savings per square foot results from the recent simulation as described above indicates robust savings from electrically heated homes, (7.59 kwh/sf) and negative (-0.02kWh/SF) savings for homes with electrical cooling. To Improve the alignment of incentive amounts with estimated savmgs available, the recommendation IS to provide a $0.50 per square foot to the electrically heated home and discontinue incentives for electrically cooled homes. Wall Insulation Adjust $0.35/SF incentive for floor insulations to: $0.30SF - electrically cooled homes $0.60/SF - electrically heated homes Currently, the program offer incentive at $0.35 per square foot with the requirement of pre-existing R -10 or less and minimum installation of R-II or greater for both electrically heated homes and electrically cooled homes. However the savings per square foot results from the recent simulation as described above indicates robust savings from electrically heated homes, (12.15 kwh/sf) and modest savings (0.31 kwh ISF) for homes with electrical cooling. To Improve the alignment of incentive amounts with estimated savmgs available, the recommendation IS to provide a $0.60 per square foot to the electrically heated home and $0.30 for electrically cooled homes. The $0.30/SF is limited by the amount the program can afford to pay for the electric energy savings estimated to be available on a per square foot basis. The R-lO or less pre-existing condition will remam unchanged. The final insulation level requirement ofr-13 is an increase compared to the current requirement ofr-i1.

Modify eligibility requirements Windows Change window V Factor from 0.35 to V-Factor of 0.30 Reason for Change weatherization and are designed to prevent multiple treatments for the same area/same measure. Proposed change is to offer an additional $200 incentive to customers who install two qualified insulation measures (attic/wawfloor) at the same time in the same house, and paid for on one invoice. Incentives will continue to be offered via post purchase applications submitted by the customer, reviewed and approved by the program administrator. All applications are subject to on-site verification. The program administrator employs a combination of methods to select applications for on-site inspections prior to payment of the requested incentive. Current installation requirements for this measure are also being revised based on market experience. The revised requirements are designed to help promote higher quality installations to Improve savmgs delivered from each participant, to align with the drive to more comprehensive weatherization projects and to prevent multiple treatments for the same measure. These requirements are available on the web site, must be adhered to for both contractor and self installed projects and are provided during weatherization contractor outreach and training conducted by the program. Incentive for windows is designed around the premise that the decision has been made to replace existing windows and the incentives and specifications are designed to improve the efficiency of the replacement window selected. Incentives are designed to cover most of the added cost of the improved window when compared to the least cost least efficient baseline window be considered. Incentives are not designed to cover a material portion of the entire window replacement cost. Replacement window specifications have improved over the past two years while the federal tax credit has been available. The added cost for the improved efficiency of the window has also declined. Changes m the window market and updated savmgs estimates indicate changes are needed to better align window qualifications with available savings and incentive amounts. Currently, the program offer incentive at $l.00 per square foot with the requirement of a V-Factor of 0.35 or lower and an SHOC of 0.33 or lower for both electrically heated homes and electrically cooled homes.

The proposed change is in the eligibility requirements; with requirement of a U-factor of 0.30 or lower to customers with electric heating systems only. Performance criteria for windows are based on climate zones and ratings certified by the National Fenestration Rating Council (NFRC). The SHGC is not required for Northern climate zone applicable to Wyoming. The incentive of $l.oo/sf of window area will remain the same.

To align incentives with available savings,, the products that are listed as torchiere or portable on the ENERGY STAR list do not qualify for incentive. Incentives will continue to be available via a post purchase incentive application completed by the customer, submitted to and approved by the program administrator. The program offers a $20 incentive for ENERGY STAR qualified ceiling fans. The original program design assumed the savings associated with fans were delivered by efficient lighting. ENERGY STAR periodically updates qualifications for rating. Program qualifications will mirror those of ENERGY STAR. While many ceiling fans that have received incentives have an integrated light kit, it has not been an explicit program requirement. The proposed change is to require the purchase of a ceiling fan with an integrated light kit, or a separate qualified light kit that can be attached to an existing fan. The current incentive will remain unchanged and continue to be offered via post purchase customer application. The program offers $250 for the customer and $25 for the contractor for the installation of a minimum 15 SEER central air conditioner. The work must be performed by a contractor. The proposed change is to add a thermal expansion valve (TXV) requirement to the existing measure qualification of 15 SEER. The incentives for the customer and contractor would remain the same. Participation to date has been low for this measure. This product is ideal for the dry climate in Wyoming, but many consumers may not be familiar with the current advances in the technology and or the full extent of the energy savings available. Units are available in the market, but not heavily promoted. The proposed change is to increase the customer incentive and add a contractor incentive. Contractors are a key sales channel for this technology, however the per job contractor margin IS smaller for an evaporative cooling project Page 15 of 41 15

Add a contractor incentive of $100 Add minimum size in Cubic Feet per Minute (CFM) New measure Evaporative Cooler - Portable Customer incentive - $75 MinimumCFM rating - 2,000 New measure Room Air Conditioner ENERGY STAR qualified Customer incentive - $25 Reason for Change compared with a unitary (compressor based) project. Providing a contractor incentive will help overcome the bias of contractors not promoting evaporative cooling projects. To help ensure incentives are provided for systems that function as the primary cooling source for a home, meet the requirement of this measure, the products must be rated at a minimum by the cubic feet per minute (CFM) of airflow 3,500 to sufficiently cool an average-sized home m Wyoming and must be the primary source of cooling for the home. This requirement will be included in the program requirements on the web site. The units may be installed in existing or new homes. While the measure is not required to be installed by a contractor, installation by a contractor is recommended. If the customer self-installs the equipment, the customer will receive only the incentive of $150 for the customer only. Incentives will be provided after submittal of a post purchase application which is approved by the program administrator. Intended to replace a room air conditioner. The barriers to evaporative technology are described above and adding a customer incentive will help promote increased evaporative installations and increase the comprehensiveness of the program for both customers and retail partners where the units are sold. This is a new measure and adding it will improve the comprehensiveness of program for customers and retailers. ENERGY STAR Room Air Conditioners use 10% less energy than conventional non-energy STAR qualified machines. Energy savings are achieved from improved compressor efficiency as well as the surface areas of the heat transfer coils which controls the amount of heat and moisture that can be removed from the conditioned air. In addition, ENERGY STAR qualified units generally come with timers which allow users to set the unit to operate only at the required times during the day. Incentives for ENERGY STAR qualified room air conditioners offer a way to help move the customer up the efficiency scale when they have made a decision to purchase a room air conditioner unit.

Bumgarner Measure Category Description of Change Modify eligibility requirements and incentive levels for an existing measure Central Air Conditioner Tuneups. Adjust the customer incentive to $20. Eliminate the contractor incentive New measure Heat Pump Tune-up Customer incentive - $100 Contractor incentive - $25 Reason for Change This new measure will offer a customer incentive of $25 for ENERGY STAR qualified models to promote the purchase of higher efficiency models. Equipment is available at several retailers in Wyoming including Best Buy, Home Depot, Sam's Club, Sears, Menards, Cost Plus, and Letz's TV and Appliance. Incentives will be available via post purchase application reviewed and approved by the program administrator. The current program provides a customer incentive of $100 and a contractor incentive of $25 to tune-up central air conditioners. The job must be performed by a contractor. The original design intent of this measure was to promote a systematic energy savmgs approach to preventative maintenance work done by a homeowner's regular HAVC contractor and to improve the focus on energy savings by HV AC contractors offering tune-up services. Savings estimates used in program planning are based on a weighted average of unit size. This was done for purposes of administrative ease and to determine whether the level of contractor interest in the measure justified program training and quality assurance follow-up. To ensure cost effectiveness at a measure level, the proposed change is to adjust the incentive for the air conditioner tuneup to $20 for the customer. The dealer incentive was eliminated based on available savmgs. Work must be performed by a program qualified contractor with the program requirements. Specific tune-up requirements for airflow and refrigerant charge are also being updated and will be available on the web site. Incentive will be paid after a customer submitted post purchase application is received and approved by the program administrator. This measure is being added to promote proper maintenance and efficiency of existing heat pump equipment. Experience to date has shown that most contractors focus on air conditioning units and overlook heat pumps. Heat pumps offer significant savings at cost effective levels. Specific tune-up requirements for airflow and refrigerant charge for heat pumps will be updated and available on the web site. Page 17 of 41 17

Increase contractor incentive to $100. Reason for Change Work must be performed by a program qualified contractor and meet the program requirements. Incentive will be paid after a customer submitted post purchase application IS received and approved by the program administrator. The program only offers duct sealing but not with the duct insulation. The duct sealing measure is designed to achieve energy savings through a systematic approach to this work. Prior to the implementation of this measure, duct sealing work was being performed in the market, but quality and attention to a systematic practice varied widely. Combining duct sealing with duct insulation into one measure furthers a systematic approach to duct performance and promotes best practices. The proposed change is to combine the duct sealing and duct insulation measures into one in order to promote best building practices, achieve greater assurance of the quality of work being performed and ensure that savings from both sealing and insulation are acquired at the same time. The Company further proposes to offer separate incentives for this combined measure for homes with electric cooling and those with electric heating, as the potential savings between these two configurations varies. Duct sealing and duct insulation must be completed by a program qualified contractor with the program requirements. Updated requirements will be available on the website. Incentives will be provided via a post purchase application submitted by the customer and reviewed and approved by the program administrator. Similar to the current practice, a sample of installations will be selected by program administrator for on-site inspections prior to payment of incentives. The program offers incentive of $350 to the customer and $25 to the contractor if the customer replaces baseboard heating or electric furnace with 8.2 or greater HSPF heat pump. The job must be performed by a contractor. To help ensure customers purchase higher efficiency (when compared to code minimum) heat pumps when the decision is made to install a heat, pump, the program recommends increasing the incentive for the customer to $400 and for the contractor to $100 for replacing current permanently installed electric heating system with an 8.2 or greater HSPF with a Thermal Expansion Valve (TXV).

Requirements for heat pump conversions will be updated and available on the web site requirements. This measure is available to customers who have an electric heat system (baseboard or resistance heat or an electric forced air furnace) serving 80% of their conditioned space, and would like to convert to a high efficiency heat pump. This measure is not available to customers wishing to convert from oil, gas, coal, or propane, or to replace space heaters. The program offers incentive of $250 to the customer and $25 to the contractor if the customer replaces baseboard heating or electric furnace with 8.2 or greater HSPF heat pump. The job must be performed by a contractor. To help ensure customers purchase higher efficiency (when compared to code minimum) heat pumps when the decision is made to install a heat pump, the program recommends increasing the incentive for the customer to $300 and for the contractor to $100 for upgrading an existing heap pump to a high efficiency model of 8.2 or greater HSPF with a Thermal Expansion Valve (TXV). Work must be performed by a contractor with the program requirements. Requirements for heat pump upgrades will be updated and available on the web site requirements This measure is not available to customers converting from a heating fuel other than permanently installed electric heat. This measure is being added to promote best practice installation and sizing of new heat pump installations to ensure an appropriately sized heat pump operates as close as possible to its design efficiency. Adding this measure align the heat pump measures with the air conditioning measures which includes and sizing incentive offer and Improves the comprehensiveness of the program for customers and contractors. The program proposes to offer a best practices installation and sizing measure to maximize heat pump efficiency and provide the customer with a $100 incentive and $100 for the contractor. Incentives are available for all new heat pump installations if the work IS performed as part of the installation. Work must be performed by a program Page 19 of 41 19

Customer incentive: $500 Contractor incentive: $100 Update existing measures and provide new measures for new homes. Reason for Change qualified contractor and meet the program requirements available on the website. Incentives will be provided via a post purchase application submitted by the customer and reviewed and approved by the program administrator. Similar to the current practice for other HV AC measures, a sample of installations will be selected by program administrator for on-site inspections prior to payment of incentives. Incentives are not currently available for this measure, however equipment is available in the Wyoming market and a few contractors have expressed interest in installing the equipment in certain applications. Ductless heat pumps are sometimes called a "mini-split" heat pump and consist of an outside compressor unit and one or more inside "heads" that deliver conditioned air to the room or rooms. Inside units are typically mounted high on the wall. The inside and outside units are connected by refrigerant lines, usually concealed in the walls or ceilings or under a cover on the outside of the house. Some models allow several indoor heads to be connected to a single outside compressor. Ductless heat pumps operate on the same principle as traditional heat pumps - using electricity to move heat between outdoor and indoor air by compressing and expanding a refrigerant. The proposed change is to offer a $500 incentive for the customer and a $100 incentive for the contractor for replacement of electric resistance heating systems with a 9.0+ HSPF and 16+ SEER single-head ductless. Space heater replacement does not qualify. The equipment must be installed by a contractor with the program requirements which will be available on the web site. Incentives will be provided via a post purchase application submitted by the customer and reviewed and approved by the program administrator. Similar to the current practice for other HV AC measures, a sample of installations will be selected by program administrator for on-site inspections prior to payment of incentives For new homes the program provides a menu of items for builders and customers to choose from to improve efficiency of new homes. Some measures like appliances have the same incentives as retrofit. Others such as weatherization 20

All incentives for new homes are available to either the customer or builder but not both. Some measures have incentives for installation contractors such as for the installation of multi-head ductless heat pumps. Refrigerator $20 incentive The current refrigerator incentives offer is available for new homes when the equipment exceeds code mmlmum requirements, but the measure has not been marketed specifically to new builders. This change helps improve the marketing of the offer to builders. The program recommends aligning with ENERGY STAR with a $20 incentive for the builder or home owner. Dishwasher $20 incentive The current dishwasher incentive offer is available for new homes when the equipment exceeds code mmlmum requirements, but the measure has not been marketed specifically to new builders. This change improves the marketing of the offer to builders. Due to the high ENERGY STAR market share, in the Wyoming market, the program recommends an increase of the efficiency level necessary to qualify for incentives. Aligning with CEE Tier 2 to ensure enough savmgs to be cost-effective. The incentive is $20 to the builder or home owner for both electric and gas water heat machines. Floor Insulation $0.35/SF Currently offer $0.15 per square foot for both electrically heated homes and electrically cooled homes. Contractor must install a minimum of R-lO beyond 2003 IECC code (R-29). Program change is to offer an incentive of $0.35 per square foot for increased floor insulation in electrically heated homes only, bringing the home's floor insulation level up to R-30. Must be installed by a contractor per the program requirements which will be available on the web site. Page 21 of 41 Attic/Ceiling Insulation $0.15/SF Currently offer 0.15 per square foot for both electrically heated homes and electrically cooled homes.

Must be installed by a contractor per the program requirements which will be available on the web site. Windows $1.00/SF The current window incentives offer is available for new homes when the equipment exceeds code mmlmum requirements, but the measure has not been marketed specifically to new builders. This change aligns the new construction offer with available savings and helps improve the marketing of the offer to builders. The program recommends offering $1.00 per square foot to the builder or home owner for installing ENERGY STAR windows with a V-Factor of 0.30 or lower in electrically heated new construction only. Must be installed per program requirements which will be available on the web site. Heat Pump with Best Practices Installation and Sizing $450 for customer or builder $150 for HVAC contractor The program currently does not offer this measure. This is a new measure for new homes. Recommendation is to provide an incentive for installation of high performance heat pumps with best practices commissioning in new homes. The incentive is $450 to the builder or home owner and $150 for the HVAC contractor. Equipment must be 9.5+ HSPF SEER with a Thermal Expansion Valve (TXV) installed by a program qualified contractor with the program requirements. Program requirements will be available on the web site. Page 22 of 41 Ductless Heat Pump - Multiple Heads $500 for customer or builder $100 for HVAC contractor The program currently does not offer this measure. This is a new measure for new homes. The multiple-head ductless heat pump measure is designed to condition the whole house with a multiple head unit rated at least 9.0 HSPF and 16 SEER. This measure is only proposed for newly constructed homes and not for existing residences. The incentive is $500 to the builder or home owner and $100 to the HV AC contractor. The equipment must be installed by a contractor with the program requirements. The latest requirements will be on the program website. 22

Bumgarner Measure Category Description of Change Reason for Change Evaporative Cooler - Permanently Installed Increase customer incentive from $100 to $150. Add a contractor incentive of $100 This is the same measure available to existing homes but the measure has not been marketed specifically to new builders. This product is ideal for the dry climate in Wyoming, but many consumers may not be familiar with the current advances in the technology and or the full extent of the energy savings available. Units are available in the market, but not heavily promoted. To help ensure incentives are provided for systems that function as the primary cooling source for a home, meet the requirement of this measure, the products must be rated at a minimum by the cubic feet per minute (CFM) of airflow 3,500 to sufficiently cool an average-sized home m Wyoming and must be the primary source of cooling for the home. This requirement will be included in the program requirements on the web site. The units may be installed in existing or new homes. While the measure is not required to be installed by a contractor, installation by a contractor is recommended. If the customer self-installs the equipment, the customer will receive only the incentive of $150 for the customer only. Incentives will be provided after submittal of a post purchase application which is approved by the program administrator. Energy Efficient Lighting changes for the Home Energy Savings program Incentives for this measure are currently provided at the manufacturer or retailer level, "upstream" from the end-use customer. This incentive delivery structure encourages customers to participate in the program by offering CFLs at a discounted price point at select retailers throughout Rocky Mountain Power's Wyoming service territory. Incentive delivery at this point in the retail sales chain results in minimal customer transaction costs and lower program administration costs. In addition, this delivery model changes customer behavior for a low cost commodity at the point of purchase; i.e., "Look for and purchase CFLs instead of incandescent bulbs at your normal retail outlet." Currently the program offers the ENERGY STAR qualified CFLs with a $2.75 not-to-exceed price at the selected retailers. Savings in this category are deemed from sales volumes and the difference in wattages from incandescent to replacement wattage. This category has performed well and continues to gain traction as time passes. All ENERGY STAR rated products qualify for the incentive. However, current not-to-exceed retail price is defined as $0.99 to $2.75 which does not permit a full range of products to be available. While there is no current incentive difference between specialty Page 23 of 41 23

149 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 24 of 41 Docket No Witness: Jeffery W. Bumgarner CFLs and general CFLs, the maximum incentive and retail price window has restricted the eligible products to a narrow representation of high quality products that are currently available at retail. Expanding the not-to-exceed retail price will permit a wider range of bulbs to be bought down. The marketplace has actively engaged utility sponsored incentives, and the environment is primed to make a massive push to increase market share of basic efficient replacements over incandescent options. The US Department of Energy has released several statements and papers indicating that CFLs have a great deal of remaining savings potential, and that the measure is still building momentum. Approximately 100 retail locations selling CFLs have been identified in the state of Wyoming. Of those, about half reside squarely in the Rocky Mountain Power territory. The program has engaged 47 retail locations to provide special pricing on CFLs. These represent retailers from large warehouse stores to small local hardware and grocery stores. While the large stores provide the majority of volume of sales, it is the active engagement of the smaller stores that leads to deeper market penetration, and the program has made concerted efforts to create relationships with every possible location, big or small. Code/Standard Review ENERGY STAR periodically updates qualifications for product. ENERGY STAR has currently released draft specifications for both lamps and luminaires. These new specifications will become effective on or near November Program qualifications will mirror these new specifications. Beginning in 2012, EISA will eliminate incandescent shipments from entering the US starting at highest wattages, and moving down each year for several years. The initial impact will result in 100 watt equivalent CFLs to have a reduced baseline for savings, affecting their eligibility to be a viable measure. Each year, the number of products eligible for incentive will decrease as the incandescent baselines are removed, as indicated on the following table: Current Maximum Lumens Incandescent Allowable Wattage Wattage Lamp Life Effective Date hrs hrs hrs hrs Recommendation Page 24 of 41 24

150 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 25 of 41 Docket No Witness: Jeffery W. Bumgarner The program recommends increasing the incentives and widening the retail price window to increase the number of eligible products, resulting in higher redemption and visibility of incentive. Recommendation to offer the ENERGY STAR qualified CFLs with maximum incentive of$1.50 for the general purpose bulbs and maximum incentive of$1.75-$3.50 for specialty bulbs based on bulb type, and not-to-exceed price at $2.50 for general purpose bulbs and at $6.00- $14.00 for specialty bulbs at selected retailers. Mid-market incentives will continue to be managed with agreements between the program administrator and retailer and/or manufacturers.

The current program offers incentives for lighting, motors, heating ventilation and air conditioning ("HV AC"), building envelope, food service equipment, irrigation, and other measures. Incentives are available for both retrofit projects and new construction/major renovation projects. This program was first offered to Wyoming customers on January 1,2009. In July 2010, PacifiCorp retained Nexant, Inc. (Nexant) to evaluate the next phase of program improvements for the FinAnswer Express energy efficiency programs. The primary objective of Page 25 of 41 25

151 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 26 of 41 Docket No Witness: Jeffery W. Bumgarner this analysis is to increase customer participation and the level of cost-effective electrical energy and demand savings realized by the programs. Description of Planned FinAnswer Express Program Changes As a result of this work, new equipment categories, new measures, changes in eligibility requirements and incentive levels are proposed for the FinAnswer Express program. The changes are designed to increase participation, savings acquisition and improve the comprehensiveness of the program for customers and trade allies. Schedule 213, which was approved since January 1, 2009, was added to the Applicable section of the Schedule to help insure that all customers with lighting opportunities have program services available. The Energy Efficiency Incentive Caps table on Sheet is updated to include the new measure groups and upward adjustment from fifty percent to seventy percent for the project cost cap for retrofit lighting and custom incentive projects. This adjustment mirrors the proposed adjustment to the Energy Fin Answer proj ect cost caps made as part of this filing. The custom energy efficiency incentive rate of $0.08/kWh has also been adjusted to $0.10/kWh to maintain the same alignment as currently exists between the Energy FinAnswer and FinAnswer Express programs. The energy code baseline utilized by the program, the International Energy Conservation Code (IECC) is referenced in the tariff, but the specific version (typically expressed as a year) has been moved to the energy efficiency program section of the Company website to enable the program to utilize a different version in the future if it is determined that common practice has changed in the Wyoming territory. The reference to a baseline for fluorescent lighting utilized by the program remains in the tariff, but the specific description (the lamp and ballast combination) will be provided on the energy efficiency program section of the Company website to enable the program to utilize a different baseline version in the future as lighting standards change. Proposed changes by measure category are outlined in the table below. Measure Description of Change Reason for Change Category Retrofit Modify existing lighting measures: T8 Fluorescent It is proposed both the lamp and ballast be CEE qualified, but not need to meet a qualifying combination. This flexibility will allow customers and their vendors to choose Modify the eligibility the most appropriate combination for the space or requirements for application. Aligning with CEE will help reduce questions 'Premium efficiency' T8 Page 26 of 41 26

152 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 27 of 41 Docket No Witness: Jeffery W. Bumgarner fluorescents to match the High Performance/Reduced Wattage T8 lamp and ballast qualifying requirements of Consortium for Energy Efficiency (CEE). Modify delamping incentives to be available where the new lamps and ballasts are Premium (delamping for Standard will no longer be eligible) Modify the eligibility requirements for High Bay T8s to match CEE High Performance Lamp requirements. Reduce the incentive for relamping and administrative complexity over ballast factor requirements in individual projects. To ensure energy savings, higher light output ballasts on the CEE Qualified ballast list may be excluded from eligibility. Any exclusions will be posted with the link to the qualified ballast list maintained on the Wyoming energy efficiency program section of the Company's website. Focusing the delamping eligibility on Premium T8 fluorescents is consistent with the planned phase-out of incentives for Standard T8s. High Bay T8s will be required to meet the CEE High Performance Lamp requirements. Relamp projects are typically end of useful life group relamping projects. Incentives have been reduced to align with the incremental material costs of relamping. Modify eligibility requirements for an existing measure: Standard T8 Add a sunset date of July 14,2012 for standard T8 incentives. Modify eligibility requirements for an existing measure: CFL Add a sunset date of January 1,2014 for screw-in Compact Fluorescent Lamps (CFL) incentives. Consolidate the CFL measures into one screwin measure and one hardwired measure. Align incentive availability with the effective date of new federal efficacy standards for General Service Fluorescent Lamps (GSFL). Savings attributed to replacing TI2 fixtures in retrofits should continue to be reported for a transition period following the sunset date to reflect that most projects will continue to be elective upgrades until such time that TI2 lamps and ballasts have only limited availability. Align incentive availability with the effective date of new federal efficacy standards for General service Incandescent Lamps (GSIL). DOE estimates that incandescent lamps currently account for over 30% of lighting energy use in the commercial sector and many customers have not yet replaced incandescent lamps. This retrofit provides one of the most cost-effective resources m the program and complements the other incentives offered in the retrofit category. Page 27 of 41 27

153 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 28 of 41 Docket No Witness: Jeffery W. Bumgarner Add new measures: LED, induction, cold cathode Non-General Illuminance Add prescriptive incentives for selected Light Emitting Diode (LED), induction, and cold cathode measures LEDs are a rapidly emerging technology with excellent energy savings potential and wide-ranging applications in the lighting industry. LEDs provide monochromatic, unidirectional light from a single point source and have extremely long equipment lifetimes. LED fixtures are made up of four components; diode, driver, heat management system, and housing. Manufacturers have marketed LEDs in a number of different fixture types to the retrofit market with varying degrees of success. Several applications for LEDs have been deemed market ready. Both ENERGY STAR and the Design Lights Consortium maintain qualifying product lists for these applications. However, high costs, low efficacies, heat management issues, and the inability to provide dimming functionality or diffuse light patterns are still a concern and continue to limit the growth of LEDs. The proposed change is to add prescriptive incentives for a select group of LED measures that comply with recognized standards such as Design Lights Consortium LED performance requirements. The products that will be added include LED equipment in the following categories. Screw-In Lamps, Recessed Downlight, Outdoor Pole, Parking Garage, High and Lowbay and Marquee/Cabinet signs. Induction is an electrodeless lighting technology that uses magnetic flux to produce light. Because there IS no electrode, the lamps have long lifetimes, as much as 100,000 hours. In addition, dimming is an option that can be utilized to provide additional energy savmgs. With the recent reduction in costs, induction is a viable option in HID applications where maintenance can be difficult or expensive. Cold cathode refers to the fact that the cathode is not independently heated, as in fluorescent lamps. Unlike fluorescent, cold cathode lamps reach full brightness instantly, can be operated in rapid cycling without degrading lifetime, and operate in cold ambient temperatures. With long lifetime and low energy usage, cold cathode screw-in lamps are an emerging replacement for many incandescent and CFL lamp applications. Currently, cold cathode is only cost-effectively available as screw-in lamps in low wattages. Change incentives for an existing measure; add new measures: Page 28 of 41 28

154 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 29 of 41 Docket No Witness: Jeffery W. Bumgarner Lighting control Increase incentives for lighting control occupancy sensors. Add a day lighting control measure. Add an advanced daylighting control measures. Add an additional incentive for each dimming ballast installed controlled by qualifying occupancy or day lighting control. Automatic lighting controls save energy by turning off or dimming lights when they are not necessary. Different varieties of sensors are available including passive infrared (PIR), dual-technology, and integral occupancy sensors, and photocells, which can be coupled with a variety of control strategies including day lighting controls and occupancy controls timer controls. The trend is toward increasing integration of multiple controls to control light levels and timing in spaces. Dimming ballasts are increasingly common m lighting control applications (in combination with sensors) and since the ballasts cost five to six times more than standard or premium ballasts. Providing an incentive to cover a portion of the required ballast should encourage greater adoption of energy savings controls. Discontinue incentives for a measure: Timeclock Discontinue incentives for timeclocks Change incentive levels for existing measures: Retrofit Lighting measures Based on industry feedback timeclocks/sweep controls have become standard in the industry and common practice for large general illuminance retrofit projects. In addition, timeclocks are either mandatory or a compliance option according to most energy codes. Discontinuing incentives for this measure while adding incentives for more advanced lighting control technologies is intended to increase the penetration of lighting controls and increase the savings from individual projects. Incentive levels in the revised Tables 1 a and 1 b reflect an average increase of approximately twenty percent and were designed to be aligned on a $/kwh basis whenever possible with incentives for new measures. Change eligibility requirements for existing measures: Retrofit Lighting measures Decouple eligibility for The large (and increasing ) number of the fixture retrofit combinations generates a compamon growth m administrative complexity to qualify projects for prescriptive incentives. Providing incentives based on the Page 29 of 41 29

155 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 30 of 41 Docket No Witness: Jeffery W. Bumgarner incentives from the existing fixture for retrofit projects and provide incentives based only on components in (lamps, ballasts) in the fixture installed. Change eligibility requirements for existing measures: Retrofit Lighting measures Provide incentives on a per lamp basis instead of a per fixture basis fixture installed, regardless of the existing fixture, allows incentives to be more easily specified and reduces the administrative complexity necessary to deal with a broader array of existing and proposed components and fixture types. Continue to report actual energy savings and measure costs for retrofit projects based on the existing and new fixture inventories using an updated version of the current retrofit lighting tool. As listed in Table la, incentives for Fluorescent T8's would be paid based on the number of lamps, where a fixed incentive would be multiplied per the number of lamps in the fixture. This simplifies the incentive table considerably and limits the number of fixtures classified as "Custom", allows the incentive to scale with the increased fixture cost and energy savings associated with larger numbers of lamps, does not limit incentives to certain pre-existing lighting configurations, and provides greater flexibility for specifying energy-saving lighting configurations that qualify for prescriptive incentives. As listed in Table 1 b, incentives for LED message center signs have been revised to a per lamp basis consistent with other LED sign measures. Measure Category New Construction! Major Renovation Lighting Description of Change Change incentives for an existing measure: Interior lighting Change to "pay for savings for savings" approach based on a program energy code baseline for interior lighting and lighting controls. Reason for Change Increased flexibility, promote more creative interior lighting design, will not restrict new technologies as they become market ready. Total project lighting power density (LPD) must be more than 10% below the program baseline code (currently IECC 2003) LPD requirement. Effective, January 1, 2010, the Energy Security and Independence Act of 2007 increased mmlmum ballast efficacy factors and established Pulse Start Metal Halides as the new industry standard baseline for the metal halide technology for fixtures with wattages 500W or less. New construction projects must use the pulse start technology in metal halide applications. The current program effective January 2009 provides incentives for pulse start metal halides:::: 125 Watts. Year to date in 2010, $720 in incentives has been paid for pulse start metal halides that are now required. An estimated $4,200 in Page 30 of 41 30

156 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 31 of 41 Docket No Witness: Jeffery W. Bumgarner additional incentives may be paid before the program changes proposed in this filing take effect. Add new measures: Exterior Lighting and lighting controls Exterior Lighting and Lighting Control measures For exterior lighting, offer per fixture incentives for the same LED and induction measures added to the retrofit lighting program and offer incentives for integral occupancy control as these measure are not required by energy codes for exterior lighting. Measure Category Motors Description of Change Modify eligibility requirements for an existing measure: Premium Efficiency Motors Add a December 19, 2010 sunset date for NEMA premium efficiency motor incentives. Reason for Change As of December 19,2010, AC induction motors up to 200 horsepower are subject to new minimum full-load nominal efficiency requirements as authorized m the Energy Independence and Security Act of NEMA Premium highefficiency motors will be explicitly required by federal code for motors sized hp. NEMA Premium applies to motors from horsepower. In preparation for the EISA 2007 change, vendor feedback indicates availability of NEMA Premium Efficiency Motors has increased for the full NEMA premium size range from horsepower. The effect of the sunset date is to discontinue prescriptive incentives for hp NEMA premmm efficiency motors and to discontinue custom incentives for horsepower NEMA Premium Efficiency Motors. The current program effective January 2009 provides incentives for premium efficiency motors from 1 to 200 horsepower. There has been vendor education regarding the change in manufacturing standard and the Company estimates no incentives will be paid between December 19, 2010 and the date the requested effective date of this filing. Page 31 of 41 31

157 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 32 of 41 Docket No Witness: Jeffery W. Bumgarner New measure: Green Motor Rewind Add a Green Motor Rewind incentive for motors 15-5,000 hp either installed or placed in inventory. A green motor rewind is the process whereby a used motor is rebuilt in a controlled and measured environment which results in the rebuilt motor being as energy efficient as the existing design of the motor allows. It is standard practice for larger motors to be rewound instead of replaced and this program feature is designed to prevent the 1-2% loss that typically occurs during standard practice rewinds. A $2/hp incentive per rewind will be provided of which at least $1 is provided to the customer as an instant incentive at the point of sale. Incentives will be provided to the participating motor service center. Measure Category HVAC Description of change Change eligibility and incentives for an existing measure category Unitary Commercial Air Conditioners, Air-Cooled Heat Pumps, Air-Cooled Add the new Integrated Energy Efficiency Ratio (leer) metric to the air conditioning equipment minimum efficiency requirements. Reason for change The program currently utilizes efficiency levels based on CEE standards to establish minimum efficiency requirements for equipment listed in Table 3. These efficiency levels standards exceeded all applicable federal standards until they changed in January CEE has revised the efficiency level tiers in response to the changed federal standards. The proposed change is utilize the updated CEE specifications to establish new efficiency requirements for the for unitary air conditioners and heat pumps (eligible for $50/ton incentives) and add incentives ($75 and $loo/ton respectively) for equipment that meets or exceeds efficiency levels based on the updated CEE specifications. The new equipment efficiency levels and incentives are provided in proposed Table 3a. Additionally, the efficiency levels should include Integrated Energy Efficiency Ratio (leer) metric in addition to the Integrated Part Load Value (lpl V). IEER is a new part load cooling metric that replaces the previous IPL V metric. The planned change aligns with the new practice for some manufacturers of providing the IEER rating instead of IPL V rating for new equipment lines. For older models, the IPL V rating is available, but not an IEER rating. The addition of this IEER rating will permit the program to provide incentives for high efficiency equipment rated using either metric. Page 32 of 41 32

158 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 33 of 41 Docket No Witness: Jeffery W. Bumgarner Until the proposed changes are approved, units that meet, but do not exceed the current requirements (which is now federal code) in Table 3 will receive an incentive, but no savings will be reported. The impact is expected to be minimal since, in 20 I 0 year to date, no units that have fallen into this category. Add eligibility and incentives for a new measures: Other HV AC Equipment and Controls Ground Source Heat Pump Loop Ground Source Heat Pump (Energy Star Qualified) Adjust incentives for an existing measure Evaporative Cooling Increase incentives from $0.02 to $0.06/ Cubic Feet per Minute (CFM) for evaporative cooling Add eligibility and incentives for a new measures: Indirect-Direct Evaporative Cooling Add new measure: Room Air Conditioner Demonstrated customer demand for the measure. Participation currently through Energy FinAnswer program, but pre-purchase site specific analysis can have construction schedule impacts. Data from completed projects, Energy Star specifications and other utility program offerings provide sufficient data for simplified analysis and post purchase approach. The measure offers substantial savmgs when compared with unitary (compressor based) cooling equipment. Increasing the per CFM incentive will result in an incentive equivalent to approximately $78/ton and will more closely align with per ton incentives for unitary equipment. Demonstrated demand for measure as part of new construction or major renovation. Participation currently through Energy FinAnswer program which can have construction schedule impact. Site specific simplified analysis will be used to calculate savings and incentive will be based on $/kwh. Some business customers purchase residential appliances for use in their business. They are not currently eligible for incentive from the Home Energy savings program which is typically discovered during the incentive application process. Currently, a business customer incentive offer in these situations is based on a site specific calculation which may be different than the per unit incentive advertised by the retailer. To address this issue, the program will add a category for residential appliances used in a business and provide the same incentive for the same qualifying equipment as the Home Energy Savings program. The program will "point to" the Home Energy savmgs program so this offer will automatically float with the residential offer. Page 33 of 41 33

159 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 34 of 41 Docket No Witness: Jeffery W. Bumgarner Envelope Add eligibility and incentives for a new measures: 365/366 day programmable thermostat Modify eligibility requirements for an existing measure: ENERGY STAR programmable thermostat Sunset incentives for ENERGY STAR programmable thermostats Add eligibility and incentives for a new measure: Reflective window film Modify eligibility requirements for an existing measure: Insulation Adjust eligibility requirements for an existing measure: Windows Extend incentive availability to site built windows. The energy efficiency of portable classrooms has been researched extensively to identify cost-effective energy savings opportunities. Outside of envelope measures, improper scheduling of the HV AC and ventilation system was noted as a significant problem in portable classrooms. Where manual on/off switches are employed, cooling/heating units commonly run when classrooms are unoccupied (summer vacation and weekends). Even when programmed correctly, 7-day thermostats operate cooling/heating units during the unoccupied summer months unless reprogrammed by facility staff at the beginning of summer vacation. To improve scheduling of HV AC systems, the proposed change is to provide eligibility requirements and incentives for 365/366 day programmable thermostat with temporary manual override be installed and configured in all portable classrooms. ENERGY STAR specifications for thermostats were suspended in December There is currently no indication that ENERGY STAR has reinstated its qualification or reached a conclusion on the energy savings associated with this measure. For these reasons the proposed change is to sunset the measure on the effective date of the tariff. Improved glazing efficiency can reduce cooling requirements. Applying reflective window film to existing windows is a lower cost alternative for improved glazing performance when compared to retrofitting existing windows with new glazing materials. Space must be mechanically cooled Incentives will be available only for retrofit projects. Incentive will be based on a $/kwh with site specific savings calculated using a simplified analysis tool. There is a current incentive offer for insulation, but there is no distinction between retrofit and new construction projects. The proposed change is to differentiate and establish added insulation levels specific to each type of projects and align the new construction levels with exceeding the minimums required by the version of the IEEC code utilized by the programs. Responds to market request to provide incentive for site built windows. Aligns efficiency requirements (U value) with requirement of the current federal tax Page 34 of 41 34

160 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 35 of 41 Docket No Witness: Jeffery W. Bumgarner Food Service Adjust U value requirement to 0.30 for both NFRC rated and site built assemblies. Adjust the SHGC value requirement from 0.40 to Modify eligibility requirements for an existing measure: Solid Door Refrigerator Solid Door Freezer Modify the minimum efficiency requirement for refrigerators and freezers to state "ENERGY STAR " credit. The current efficiency requirements for solid door refrigerators and freezers are based on CEE specifications and includes three SIze categories. Effective January 1, 2010 ENERGY STAR and CEE have aligned their specifications for refrigerators and freezers to match the current ENERGY STAR Version 2.0 specification The ENERGY STAR specification includes glass-door refrigerators and freezers, and chest refrigerator/freezer configurations in addition to the solid-door refrigerators and freezers currently eligible for incentives through the FinAnswer Express program. The proposed change is to update the eligibility requirements to match the current ENERGY STAR Version 2.0 requirements. Using the ENERGY STAR specification will expand the number of refrigerator/freezer configurations eligible to receive incentives. Until the proposed changes are approved, units that meet, but do not exceed the Tier 1 requirements (which is now federal code) in Table 3 will receive an incentive, but no savings will be reported. The impact is expected to be minimal since, in 2010 year to date, no units that have fallen into this category. No participation IS estimated between now and the requested effective date. Page 35 of 41 Modify eligibility requirements for an existing measure. Beverage or refrigerated display machine occupancy sensor New eligibility requirements will be tied to entire machines that meet a Maximum Daily Energy Consumption (MDEC) requirement. Currently an incentive is provided for a sensor that is added to control an existing machine. Typically the sensor is not integral to the machine. The control options for vending machines have been changing over the recent years and this change is intended to align with those changes. The proposed change is to offer an incentive for the purchase of entire Refrigerated Vending Machines that meet minimum efficiency requirements. Currently, ENERGY STAR maintains a specification for Refrigerated Vending Machines, and the Code of Federal Regulations includes requirements for refrigerated vending machines that go into effect 35

161 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 36 of 41 Docket No Witness: Jeffery W. Bumgarner An August 31, 2012 sunset date will be added to align with new federal minimum efficiency standards. August 31, Since the ENERGY STAR specifications are not as stringent as the upcoming pending federal efficiency requirements, it IS recommended that the federal efficiency regulations be used as the minimum efficiency requirements to be eligible for an incentive until the regulations become effective. Once the federal efficiency requirements become effective, incentives will be discontinued. Appliances New measures: Add eligibility criteria and incentives for new measures. Commercial dishwashers Electric insulated holding cabinet Electric steam cooker Electric convection oven Electric combination oven Electric commercial fryer Air cooled ice machines Residential dishwasher Residential refrigerator LED Case Lighting New category and new measures: Residential clothes washer Residential electric water heater Provide incentive for selected residential appliance used in a business. Food service equipment is either purchased new or to replace failed equipment. Per unit incentives and a post purchase incentive application process are the most effective way to influence customers to purchase (and dealers to stock! order) high efficiency equipment. The proposed change is to add minimum efficiency requirements and incentives for the following commercial food service equipment; commercial dishwashers, electric insulated holding cabinet, electric steam cooker, electric convection oven, electric combination oven, electric commercial fryer and air cooled ice machines. In addition, this category will "point to" the Home Energy Savings program for qualifying equipment requirements and incentive for residential dishwashers and refrigerators that are used in a business. The explanation is provided in the appliance section of this table. In addition, a new measure to replace fluorescent lighting with LED on refrigerated cases has been added. New equipment tends to come with LEDs, so the new measure is limited to retrofits of existing equipment only. Some business customers purchase residential appliances for use in their business. They are not currently eligible for incentive from the Home Energy savings program which is typically discovered during the incentive application process. Currently, a business customer incentive offer in these situations is based on a site specific calculation which may be different than the per unit incentive advertised by the retailer. To address this issue, the program will add a category for residential appliances used in a business Page 36 of 41 36

162 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 37 of 41 Docket No Witness: Jeffery W. Bumgarner and provide the same incentive for the same qualifying equipment as the Home Energy Savings program. The program will "point to" the Home Energy savmgs program so this offer will automatically float with the residential offer. New category and new measure: Commercial clothes washer Similar to food service equipment, the opportunity to upgrade this equipment is during initial purchase or replacement. Adding a per unit incentive for high efficiency clothes washers for equipment that meets or exceeds Energy Star or CEE (higher efficiency) minimum efficiency requirements will help improve efficiency when purchases are made. Incentives will be available post purchase application. Office equipment New measure: Network PC Power Management Software To help provides customers tools to reduce office equipment consumption, incentives for Network PC Power Management Software was added to this category. Irrigation Modify eligibility requirements for existing measures. Add new measures. (See Table 5 in the current program tariff and Table 8 in the proposed tariff for lists of existing and new measures) The current offer for irrigation equipment is in Table 5 of the existing Schedule. Several sets of changes are proposed based on feedback from equipment dealers and customers regarding equipment configurations practices. All changes are designed to reduce transaction complexity and since most equipment is purchased and installed during down times with little time for site specific analysis. All changes are designed to increase participation. Revisions to exlstmg measure eligibility and incentives in addition to new measures eligibility and incentives are included in Table 8 included with the filing. All incentives will be available via a post purchase application process. Dairy/Farm Equipment New category and new measures: Automatic Milker Takeoffs Agricultural Engine Block Heater Timers Agricultural energy usage is estimated at 14% offarm expenditures (Energy Situation for Agriculture, 2005) and the agricultural sector continues to explore opportunities to reduce these costs and is receptive to measures aimed at improving energy efficiency.

Bumgarner Compressed air Circulating Fans Heat Reclaimers High Efficiency Livestock Waterers High Efficiency Ventilation Systems Milk Precoolers Programmable Ventilation Controller VFDs for Dairy Vacuum Pumps New category and new measures: Low Pressure-Drop Filters Receiver Capacity Addition Refrigerated Cycling Dryers VFD Controlled Compressor Zero Loss Condensate Drains Outside Air Intake The proposed additions are informed by a combination of customer and vendor requests and research performed by Nexant, Inc. on other energy efficiency program offerings for similar measures. Compressed air project are currently handled through the Energy FinAnswer program which identifies site specific savings and requires a pre-purchase agreement. Most smaller compressed air projects are driven by the need for enhanced capacity or failed equipment which may limit the time to analyze and influence purchase decisions. Experience in other markets has shown the measures listed are appropriate to handle prescriptively which increases participation. Incentive for larger compressed air projects will continue to be managed through the Energy FinAnswer program. Energy FinAnswer - Schedule 125 Background The Energy FinAnswer program has been offered to Wyoming business customers as a loan based program since the early 1990' s. The program was modified to become an incentive based program when the Company proposed to offer its other demand-side management programs in Docket No EA-06. The program provides Company-funded energy engineering, incentives of $0.12 per kwh of first year energy savings and $50 per kw of average monthly demand savings up to a cap of 50 percent of the approved project cost. The program is designed to target comprehensive projects requiring project specific energy savings analysis and operates as a complement to the more streamlined FinAnswer Express program. In addition to customer incentives, the program provides design team honorariums (a finder fee for new projects) and design team incentives for new construction projects exceeding International Energy Conservation Code ("IECC") 2003 energy code by at least 10 percent. In July 2010, PacifiCorp retained Nexant, Inc. (Nexant) to evaluate the next phase of program improvements for the FinAnswer Express and Energy FinAnswer energy efficiency programs. The primary objective of this analysis is to increase the level of cost-effective electrical energy and demand savings realized by the programs. Consistency across PacifiCorp's service territories and with programs offered by neighboring utilities is also a major consideration to simplify Page 38 of 41 38

164 Rocky Mountain Power Exhibit RMP_(JWB-2) Page 39 of 41 Docket No Witness: Jeffery W. Bumgarner program implementation, reduce administrative costs, and avoid customer confusion in the marketplace. The approach to the work consisted of in-depth analytics of historical Energy FinAnswer project impacts, results of reviews of other utility programs, program barrier reviews, publicly available market assessments, and Nexant's professional experience. Description of Planned Energy FinAnswer Program Changes As a result of this work, Nexant has identified that the current incentive levels through the Energy FinAnswer program are squarely in the middle with respect to other utility offerings. However, the retail electricity rates create longer-than-average paybacks when compared with other utility programs. Additionally, the current economic environment has placed downward pressure on project economics. As such, Nexant recommends increasing incentive levels to overcome economic barriers to project implementation and help energy efficiency projects compete for available capital. During the course of the research, barriers beyond capital access and project economics were identified through primary customer research or through review of work already completed including the process evaluation of the program completed in 2007 for the program in Utah and Washington. One of the primary barriers identified is time constraints and competing priorities within customer organizations. Identifying and developing energy efficiency projects on either a standalone basis or as part of larger project requires dedicated technical and financial talent in order to successfully compete for funding. The energy engineering services provided by the program help overcome the technical barriers, but it is only a component of the overall project and is performed by third party consultants outside of the customer's organization. To overcome the financial barriers faced by customers, the planned change is to increase incentive levels. The following table illustrates the current and proposed incentive levels. Current and Proposed Energy FinAnswer Incentive Levels Incentive Formula Project Incentive Caps Current $0. 12/kWh + $50/KW 50% of project cost 1 year payback Proposed $0. 15/kWh + $50/KW 70% of project cost 1 year payback To overcome the commonly referenced barrier to implementation of energy efficiency projects, namely that customers are often thinly staffed to the point that energy efficiency efforts stall or are not fully developed due to lack of technical manpower at the site. The planned change is to add a co- funding option for customer energy proj ect managers ("EPM") and overcome this barrier for customers with efficiency opportunities. The goal of the EPM co-funding is to increase customer management and engineering efforts devoted to electrical energy efficiency projects and increase the number of projects entering the business customer programs. The basic premise of the EPM co-funding is that the participating customer sets their own annual energy savings goal (in consultation with Rocky Mountain Power) and then receives co-funding proportionate to the goal (subject to minimum and maximum co-funding levels). Initially the cofunding will be available to customers who sign an agreement to complete energy savings Page 39 of 41 39
