PAC-06- , '.. ) Direct Testimony of Brian S. Dickman PACIFICORP CASE NO. PAC-06- September 2006 Please state your name, business address and present position with PacifiCorp dba Rocky Mountain Power (the Company). My name is Brian S. Dickman, and my business address is 201 South Main Street Suite 2300, Salt Lake City, Utah. My current position is Manager, Idaho Regulatory Affairs. Qualifications Please briefly describe your educational and professional background. I received a Bachelor of Science Degree in Accounting from Utah State University in 2001 and a Masters of Business Administration from the University of Utah in 2002. Prior to joining PacifiCorp in 2003, I was employed as an analyst for Duke Energy Trading and Marketing. At PacifiCorp, I worked as a revenue requirement analyst before taking my current position. I have been involved in the preparation and prosecution of numerous filings with public utility commissions in PacifiCorp s six-state service territory. What are your current responsibilities as Manager of Idaho Regulatory Affairs for Rocky Mountain Power? My current responsibilities are focused on managing the Company s regulatory filings in Idaho. I am involved in regulatory planning and analysis and serve as PacifiCorp s external contact for regulatory issues in Idaho. What is the purpose of your testimony? The purpose of my testimony is to support the Company s petition for a declaratory order to determine the appropriate payment structure of Schedule No. 21. Dickman, Di - 1 PacifiCorp Why is the Company petitioning the Commission for such an order? PacifiCorp had previously committed to the Community Action Partnership Association of Idaho ("CAP AI") that it would make a filing with the Commission to address the structure of funding provided by the Company for low-income weatherization services under Schedule No. 21. In Commitment I13b, adopted in Order No. 29998, Case No. P AC-05- the Company agreed to include in the direct testimony of its next general rate case an analysis of the costs and benefits of changing its current practice of matching 50 percent of federal contributions for low-income weatherization measures to matching at a higher percentage amount. Commitment I13b was accepted, based on a previous stipulation in Case No. P AC-05-, Order No. 29833, which proposed a general rate case was to be filed by the Company, no later than April , 2006, to address an unresolved and unrelated cost of service issue. On June 21 2006, the Company made three applications with the Commission to adjust rates for tariff Schedule Nos. 10 400, and 401 (Case Nos. PAC-06-, PAC-06-, and PAC-06-9). The above applications are based on settlement agreements reached between PacifiCorp and the representatives of customers served under the respective rate schedules. PacifiCorp contends that pending Commission approval of the applications, a general rate case would no longer be needed during 2006. In an attempt to honor its commitment made in Case No. P AC-05-, the Company sought agreement from CAP AI to address the issues raised Commitment I13b in a filing other than a general rate case. Such an agreement Dickman, Di - 2 PacifiCorp was reached and, on June 19 2006, the Company and CAPAI executed the stipulation attached hereto as Exhibit 1. As part of the stipulation PacifiCorp agreed to make a filing before the Commission no later than September 1 , 2006. Did the Company agree to anything else in exchange for CAP AI's agreement to forgo a general rate case? Yes. PacifiCorp agreed to (1) contribute $10 000 each to SouthEastern Idaho Community Action Agency ("SEICAA") and Eastern Idaho Community Action Partnership ("EICAP") to be used as energy assistance for the Lend-a-Hand program during the 2006-2007 heating season, and (2) support legislation sponsored by CAP AI during the 2007 Idaho general legislative session, that would give the Commission authority to approve discounted rates for low-income customers if requested by a utility. An example of such legislation is included as an attachment to the stipulation provided in Exhibit 1. The proposed legislation would give the Commission authority at its discretion to establish a preferential rate for low-income customers, with program costs recovered from other utility customers. While the Company has committed to support the proposed legislation, it has not committed to request or establish such a bill discount program in Idaho. Please describe PacifiCorp s initiatives to assist low-income customers in its service territory. PacifiCorp has had a variety of programs in place to assist households in financial crisis with their energy needs for many years. Its Low-Income Weatherization program has been in effect since 1988 , with over 600 homes completed to date. Dickman, Di - 3 PacifiCorp The Company has also donated, and solicited donations, to the Lend-a-Hand energy assistance program for many years through envelopes distributed in November and February billings. PacifiCorp has matched all contributions to Lend-a-Hand since November 2000. PacifiCorp recognizes the importance of providing services to households with limited income. The Low-Income Weatherization Program is a demand side management DSM") program intended to reduce electricity consumption and monthly bills by increasing the efficiencies oflow-income homes. PacifiCorp partners with EICAP in Idaho Falls and SEICAA in Pocatello to provide energy efficiency services, at no cost to income-qualifying households, through Schedule No. 21. PacifiCorp reimburses the agencies 50 percent of the cost of installing approved cost-effective measures. Federal funding is available to the agencies that cover the remaining costs so that the services are provided at no charge to participating households. The Company s dedication to its low-income customer programs is further illustrated by the commitments made as part of the MidAmerican Energy Holdings Company purchase ofPacifiCorp, Case No. P AC-05-8. In Commitment 114, PacifiCorp committed to a total contribution level from all sources to low-income bill payment assistance in Idaho of $40 000 annually for a five year period beginning July 1 , 2006. This ongoing contribution will substantially increase annual contribution levels. Through Commitment 115 PacifiCorp will provide shareholder funding to study an arrearage management project. In Commitment 141 , PacifiCorp agreed to initiate a collaborative effort to Dickman, Di - 4 PacifiCorp track low-income issues by identifying and collecting data pertinent to low- income customers in the Company s Idaho service area. Has PacifiCorp made any recent changes to Schedule No. 21? Yes. Pursuant to Commitment I13a, Case No. PAC-05-, and as approved by the Commission in Tariff Advice 06-03, effective August 1 , 2006, PacifiCorp will reimburse the agencies up to 100 percent of the cost of installing approved measures if government funds are exhausted. Also, effective August 1 2006, the previous maximum average investment per household of$1 500 is no longer applicable. Instead, PacifiCorp will reimburse costs as described above with no per household maximum or average payment applied, providing the partnering agencies more flexibility in administering the program. The Company will continue to reimburse its partnering agencies 15 percent of the Company s rebates on each completed home to cover their administrative costs. Total PacifiCorp funding available continues to be subject to a cap of$150 000 annually. Why is it important that the Low Income Weatherization Program be cost effective? As stated earlier, the Low-Income Weatherization Program is a DSM program intended to reduce electricity consumption and monthly bills by increasing the efficiencies oflow-income homes. Not only do individual customers benefit from weatherization services, but all PacifiCorp customers in Idaho benefit from the reduced electricity demand on PacifiCorp s system, which results in lower incremental power supply costs. As a DSM program, funding for Schedule No. 21 is recovered from customers through the Schedule No. 191 Customer Efficiency Dickman, Di - 5 PacifiCorp Services Rate Adjustment. It is important that the funding burden of the program is matched with the benefit of reduced energy usage and net power costs. What services are provided to customers through the Low Income Weatherization Program? PacifiCorp provides financial assistance to its partnering agencies on approved measures under Schedule No. 21. The agencies use a Department of Energy approved audit to determine if shell measures, including insulation and window replacements, are cost effective in electrically heated homes. Other measures are available to increase electric efficiencies such as water heating measures in homes with electric water heaters and efficient lighting and refrigerators in all homes. Has the Company provided the Commission with an analysis of the program s cost effectiveness? Yes. PacifiCorp previously provided the Commission an analysis ofthe Low Income Weatherization Program in support of proposed program revisions in September 2005. That analysis included the results of a cost effectiveness study based on estimated kWh savings and number of installations by measure and is provided as Exhibit 2 of my testimony (refer to page 11-2 for cost effectiveness calculations). At that time and under the reimbursement policy of 50 percent matching rebates, the program narrowly passed the Utility Cost Test under the Integrated Resource Plan (HIRP") Decrement approach for quantifying the expected benefits. If the reimbursement portion is increased, the Company is concerned that fewer PacifiCorp customers will be provided weatherization services. An increase Dickman, Di - 6 PacifiCorp in the Company s reimbursement would mean a larger percentage of program costs would be covered through funds collected from Schedule No. 191 and a smaller percentage through federal tax funds. Because total program expenditures are capped, the total cost to the utility would remain relatively unchanged, but the benefits of the program would be reduced, due to fewer homes receiving installed measures. Not only would fewer low-income customers in the Company s service area receive energy efficiency services, but the benefit of reduced energy usage and lower incremental power costs would no longer be shared by PacifiCorp Idaho customers, making the program less cost effective. In fact, the benefits of the energy efficiency services could be shifted to customers of another gas or electric provider through federal funds no longer available to PacifiCorp customers. PacifiCorp believes that the costs and the benefits of the weatherization program should be aligned and that the cost effectiveness of the program should be maintained. As an example, if on average the cost of completing energy efficiency services on a qualifying home is $3,000, the Company s reimbursement for measures plus the 15 percent administrative cost rebate would total $1 725. At this rate, 87 homes could be completed with PacifiCorp s annual budget of $150 000. Reimbursement of75 percent of costs under this scenario results in the potential completion of 58 homes, and reimbursement of 100 percent of costs results in only 45 homes completed annually. This example illustrates that considerably fewer PacifiCorp customers would benefit from these energy efficiency services if the funding policy is revised. Dickman, Di - 7 PacifiCorp Has the Company analyzed the program s cost effectiveness since September 2005 ? Yes. An updated cost effectiveness analysis is provided as Exhibit 3. This update provides cost effectiveness results under three reimbursement scenarios: PacifiCorp reimburses 50% of costs, federal funding covers 50% PacifiCorp reimburses 75% of costs, federal funding covers 25% PacifiCorp reimburses 100% of costs, federal funding covers 0% As shown in Table 3 of Exhibit 3, under a 50 percent reimbursement scenario the program continues to pass the Total Resource Cost Test and the Utility Cost Test. Under a 75 percent reimbursement scenario , the program no longer passes the Utility Cost Test (Table 6). And finally, under a 100 percent reimbursement scenario, the program fails both the Total Resource Cost Test and the Utility Cost Test (Table 9). Costs included in the calculations are those provided by PacifiCorp only. Federal funds aren t included because Quantec includes only local funding in their calculations which could include utility contributions as well as any other funding from state and local entities. Does the Company plan to monitor the program in the future? Yes. As stated in Section III of Exhibit 2, PacifiCorp plans to have an impact evaluation completed on program results once the Low Income Weatherization Program revisions approved in January 2006 (Order No. 29952) have been in place for two years. The evaluation plan is included in Section III of Exhibit 2. The Company will review these results in 2008 to determine if program changes should be made, including changes to the reimbursement policy. In addition, the Company will file a report by May 1 of each year, beginning May 1 , 2007 Dickman, Di - 8 PacifiCorp detailing its Idaho DSM activities and program cost effectiveness, including the Low Income Weatherization Program. What does PacifiCorp recommend with respect to the reimbursement levels provided under Schedule No. 21? The Company recommends no change to the current structure of Schedule No. 21 including the level of reimbursement provided in relation to available federal tax money. Providing weatherization services is an important component in the Company s mix oflow-income program offerings. The current 50 percent reimbursement policy is consistent with the low-income weatherization programs the Company offers in its other service areas. This policy allows customers to receive benefits from their tax dollars as well as cost-effective services from this demand side management program. Using federal grants to cover 50 percent of program costs provides benefits to all PacifiCorp customers in Idaho, regardless of income or participation in the Low Income Weatherization Program, because all customers benefit from cost effective energy efficiency investments. PacifiCorp requests that the Commission determine the current payment structure is appropriate based on the reasons stated above. Does this conclude your testimony? Yes. Dickman, Di - 9 PacifiCorp Case N~. PAC-06- Exhibit No. BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION P ACIFICORP Stipulation and Agreement. September 2006 STIPULATION AND AGREEMENT This Stipulation and Agreement ("Stipulation ) is entered into by and between PacifiCorp, doing business as Rocky Mountain Power ("PacifiCorp" or the "Company ) and the Community Action Partnership Association ofIdaho ("CAP AI") (collectively referred to as the Parties ) as of June 19, 2006. I. INTRODUCTION The tenns and conditions of this Stipulation are set forth herein. The Parties agree that this Stipulation represents a fair, just and reasonable compromise of the issues raised between the Parties. II. BACKGROUND In the Stipulation settling the general rate case filed by the Company in Docket No. PAC-05-1, PacifiCorp proposed that certain cost of service issues would be addressed in a general rate case that was anticipated to be filed no later than April 29, 2006. PacifiCorp desires to not file a general rate case in Idaho in 2006 and anticipates making a filing to address certain price changes on a limited basis rather than through a general rate case. If the Idaho Public Utilities Commission (the "Commission ) approves a limited issue application, then the Company will not have the need to file a general rate case in 2006. CAP AI is willing to support PacifiCorp in its approach to avoid the need for a general rate case in 2006. This Stipulation sets forth the terms and conditions under which the Parties agree to be bound with respect PacifiCorp s approach to a limited issue filing and avoidance of the need to file a general rate case in 2006. In anticipation of executing this Stipulation, representatives of PacifiCorp and CAP AI have held discussions several times pursuant to IDAP A 31.01.01.271 and engaged in settlement discussions with a view toward resolving the issues raised herein. Based upon the settlement discussions between the Parties, as a compromise of the Parties' positions on the STIPULATION - Page I subjects discussed herein, and for other consideration as set forth below, the Parties agree to the fo llo wing terms: Ill. TERMS OF THE STIPULATION No later than August 31 , 2006, PacifiCorp shall make a one-time cash contribution of shareholder money often-thousand dollars ($10 000) to each of SouthEast em Idaho Community Action Agency ("SEICAA") and Eastern Idaho Community Action Partnership ("EICAP") (for a total aggregate contribution of twenty-thousand dollars ($20,000)) to be used as funding assistance for the Lend-Hand program for the 2006-2007 heating season. No later than September 1 2006, PacifiCorp shall make a formal filing before the Commission to address those issues that PacifiCorp and the MidAmerican Energy Holdings Company agreed to address pursuant to Commitment No. I 13(b) in Docket No. P AC-05- PacifiCorp agrees to provide support for legislation sponsored by CAP AI during the 2007 general Idaho legislative session that would give the Commission authority to approve discount rates for low income customers that are requested by utilities. The Company s support is limited to legislation allowing: 1) a utility to propose bill discounts on a strictly voluntary basis and subject to Commission approval, and 2) the costs and lost revenue from such discounts to be included in the utility s cost of service to be recovered in rates from other customers. An example of such legislation is attached as Exhibit A to this Stipulation and is subject to modification and approval by the Idaho legislature. The terms of this Stipulation shall not bind the Company to request or agree to establish such a bill discount in Idaho. CAP AI agrees to waive the Company s commitment to file a general rate case per the Stipulation in Case No. PAC-05-1 and will not make any objection to the Company applications seeking rate increases for Monsanto Corp., Nu- West Industries, Inc. and PacifiCorp s irrigation customers. In addition, CAP AI agrees that Commitment No. I 13(b) in STIPULA nON - Page 2 Docket No. P AC-05-8 will be addressed in the filing referenced in paragraph 5 of this stipulation rather than in a general rate case. The Parties agree that this Stipulation represents a compromise of the positions of the Parties on the issues addressed herein. Other than the above referenced positions and any teStimony filed in support ofPacifiCorp s Application and except to the extent necessary for a Party to explain before the Commission, if necessary, its own statements and positions with respect to the Stipulation, all negotiations relating to this Stipulation shall not be admissible as evidence in any legal or regulatory proceedings regarding this subject matter. No Party shall be bound, benefited or prejudiced by any position asserted in the negotiation of this Stipulation, except to the extent expressly stated herein, nor shall this Stipulation be construed as a waiver of the rights of any Party unless such rights are expressly waived herein. No fmdings of fact or conclusions of law other than those stated herein shall be deemed to be implicit in this Stipulation. This Stipulation shall be governed in accordance with the laws of the State ofldaho.

A- Low-Income Weatherization Program Analysis in Support of Tariff Filing 08/22/05 Case No. PAC-O6- Exhibit 2 Program Description The current Low Income Weatherization Program has been in place for over ten years. It is available to Utah Power customers with incomes at or below 150% of federal poverty guidelines that have installed electric heating systems. Services are provided at no cost to participants because partnering agencies are able to leverage Utah Power funding with federal and state funds they receive. Utah Power offers rebates directly to the Eastern Idaho Special Services Agency and the SouthEastern Idaho Community Action Agency ("Agencies ) that administer the Program. The average annual number of completions during the period 2000 through 2004 is 23. Utah Power in consultation with their two partnering non-profit agencies is proposing revisions to the current program (Schedule 21). There are four goals to this effort. 1. To increase Utah Power customer participation numbers. 2. To provide incentives for the installation of additional cost effective measures. 3. To offer rebates on measures that reduce electricity consumption in homes regardless of heating source. 4. To reimburse agencies for services up to two times per home, one time per measure. This allows the installation of new technologies and/or measures that previously were not considered cost effective. The agencies provided expected participation rates for the revised program based on their historic weatherization program experience. Estimates are presented in Table 1.1. Table 1.1: Expected Annual Participation Rates Electric Base Load Program Participants Electrically Heated Homes 170 Proposed Rebates: The following summarizes Utah Power s proposed reimbursement available to the Agencies for the installation of approved measures and reimbursement on administrative costs: A rebate averaging up to $1 500 per home annually (April 1 through March 31) will be provided towards the cost of installed qualifying Major and Supplemental Measures. The following measure categories will be eligible for rebates: Low-Income Weatherization Program Analysis in Support of Tariff Filing 08/22/05 Case No. PAC-O6- Exhibit 2 Weatherization Measures in Electrically Heated Homes Compact Fluorescent Light Bulbs (CFLs) Refrigerator Replacements Water Saving Measures in Homes with Electric Hot Water Heaters Weatherization Major Measures with a Savings to Investment Ratio (SIR) of 1.0 or greater are required (based on results of the State ofIdaho Weatherization Energy Analysis) on homes with an electric heating system that is operable and permanently installed with the capacity to heat at least 51 % of the dwelling. If physical barriers exist that prohibit the installation of a measure, the measure is not required. A list of qualifying measures follows. Greater R-values than listed below may be installed as long as audit results show it to be cost effective: Insulation up to R-48 for ceilings with less than R-30 in place. Floor insulation over unconditioned spaces up to R- Insulation (not urea-formaldehyde) up to R-26 for walls without insulation installed Class 40 replacement windows Supplemental Measures qualify for a rebate when they are determined to be cost effective. Funding is available on the following Supplemental Measures installed in electrically heated homes: Attic ventilation when installed with ceiling insulation Ground cover and water pipe insulation when installed with floor insulation Forced air electric space heating duct testing, insulation, and sealing in unconditioned spaces Weather stripping and/or caulking including blower door assisted air sealing and duct sealing Thermal doors Timed thermostats on centrally controlled multi-room heating/cooling systems Funding is available on the following supplemental measures installed in all homes: Low-Income Weatherization Program Analysis in Support of Tariff Filing 08/22/05 Case No. PAC-06- Exhibit 2 Compact fluorescent light bulbs - limit 8 Energy Star certified bulbs per home placed in fixtures that are on 2 hours or more per day. Refrigerators identified in the Weatherization Assistance Program Technical Assistance Center (W APT AC) database as having mean annual usage of900 kWh or greater may be replaced with an Energy Star model with estimated annual consumption of 500 kWh or less. Replaced refrigerators must be removed and recycled in accordance with EP A guidelines. Pipe insulation, energy-efficient showerheads, and aerators for homes with an electric water heater. Administrative Cost Reimbursement will be provided at 15% of Utah Power reimbursement for Major and Supplemental Measures with a minimum of $150 on homes with at least one major measure installed and $50 on homes without the installation of a major measure, not to exceed the following per building (Table 1.2). Table 1.2: Program Administration Dwelling Units/Building Maximum Payment Minimum Payment - $150 wlmajor measure, $50 without major measure 1 to 4 $350 5to1O $800 11to15 $1,200 16 to 20 $1,400 21 to 25 600 26 to 30 800 31+$2,100 Table 1.3 displays the assumptions used in the Program design and conducting cost-effectiveness analysis. The U.S. DOE estimates the average cost per home throughout the nation is $2 744 (based on the 2005 DOE Weatherization Guideline). The average total cost of homes completed through the Utah Power program in 2004 was $1 678. Expected savings are based on an Oakridge National Laboratory study of weatherization programs. These savings include the Major Measures and Supplemental Measures with the exception of CFLs, and refrigerator replacements, which are separately estimated below. We used a 30-year economic life for the weatherization component of the Program. Overall weatherization measures were assumed to have a 30-year economic life.

Compact Fluorescent Light Bulbs (CFL) Utah Power will pay 50% of the bulb cost for up to eight ENERGY STAR certified CFLs per home, to be placed in lighting fixtures that are in use for two or more hours/day. Table 1.4 displays the assumptions used in the CFL portion of the Program and in conducting cost-effectiveness analysis. Estimates of CFL cost were derived from several other recent programs. The average wattage of replaced bulbs, installed bulb wattage, and expected number of hours of use were derived from PacifiCorp s evaluation of its CFL program in Utah. The total number of CFLs to be installed is determined by multiplying the expected participation level from Table 1.1 (170 households) by eight. The program requirements will limit installations of CFLs to locations with at least two hours of use per day. With a minimum of two hours per day, we assumed an overall average use time of three hours per day across the installed CFLs. Average energy savings as a result ofCFL replacement is calculated as the difference in wattage between the average incandescent light bulb (70 Watts) and the replacement CFL (20 Watts), multiplied by hours of use per day (3 hours) and days per year (365). This product is then converted to kWh by dividing by 1 000. The economic life of a CFL light bulb (9 years) is determined by assuming 10 000 hours of bum time divided by the annual hours of use (10 000/(3*365)). Agency administrative payments are limited to 15% of the Utah Power estimated contribution of$1 700.

On the benefit side, it includes reduction in supply costs. On the cost side, it includes costs incurred by both Utah Power and the other funders. We also include a TRC test that includes a 10% conservation adder (PTRC). Utah Power (Utility Cost Test; UCT): From the Company s perspective the benefits are in the form of avoided supply and line-loss costs. The costs include administration, evaluation, and rebate costs associated with the program. Ratepayers: All ratepayers (participants and non-participants) may experience an increase in rates to recover lost revenue. This test (entitled Ratepayer Impact Measure, RIM) includes all the Company s program costs as well as first-year lost revenues. On the benefits side, it includes all avoided energy and capacity costs. The participant test is included but no benefit cost ratio is calculated due to zero participant costs. Cost-effectiveness assumptions are summarized in Table II. 1. Table 11.1: Program Cost-Effectiveness Assumptions Item Assumptions Energy Savings Savings by measure Retail Rate Average 2004 Residential Retail Rate Discount Rate The US Treasury Long Term Composite bond rate of 4.60% posted on August 10, 2005 was used for the TRC.

Avoided Costs Primary source is the 2005 Integrated Resource Plan 65% load factor decrement. We also used the June 31, 2005, official Company forward price curve as a secondary data source. Measure Cost Each measure has its own expected cost. Incentive Amount Varies by element. See previous sections. Results The cost effectiveness of the Idaho Low Income Weatherization Program was calculated using Quantec s Demand Impact and Cost Effectiveness (DICE) Low-Income Weatherization Program Analysis in Support of Tariff Filing 11- 08/22/05 Case No. PAC-O6- Exhibit 2 model. The model distributes the estimated annual kWh savings across the year based on hourly residential load shapes for each measure. Each of these hourly savings values is multiplied by the associated hourly avoided-costs from PacifiCorp s market price forecasts. These products are all discounted back to the present. This approach accurately captures the hourly differences in the value of a kWh during the year. Cost effectiveness was calculated based on avoided costs estimated through the August 2005 IRP decrement approach using a 65% load factor and on the Company s official market price forecasts base case for Palo-Verde Hub dated June 31 , 2005. The proposed Program design passes the utility cost effectiveness tests from the UCT perspective under both the forward price curve scenario and under the IRP decrement . The program passes the TRC under the forward price curve scenario and narrowly fails the TRC under the IRP 65% load factor decrement scenario. Neither scenario reflects the additional benefits associated with low-income weatherization to both the utility and the participant. These additional benefits include decreases in collections and arrearages, improved comfort, improved health, fewer work and school absences, less frequent moves and more money to spend on other necessities.

Estimate actual energy (kWh) and demand (kW) savings 2. Analyze Program cost effectiveness The Company has committed to a process and impact evaluation at the end of the second program year. Impact Evaluation The impact evaluation will include collecting key data, selecting a random sample of participants, estimating energy savings, and assessing cost effectiveness. The impact evaluation approach will vary by type of measure installed. Weatherization/Shell This is not expected to be a large part ofthe Program. Energy impacts will assessed through billing analysis, and demand impacts will be assessed using residential load shapes from secondary sources. Compact Fluorescent Light bulbs The analysis will begin with the Program database for the number of CFLs installed, initial and final wattage, and hours of use whenever available. Program database will be used to verify number of CFLs installed, hours of use, whether the replaced bulbs were in working condition, and number of bulbs removed. It is recommended that this effort be enhanced with a survey of about 100 participants to verify the information in the program database. However, this may also lead to increasing overhead costs to prohibitive levels given the size of this program. The data collected will be used to estimate the energy (kWh) savings. The evaluator will then use secondary lighting hourly use data to estimate the Program demand (kW) impacts. Actual savings will be verified with billing analysis as described below. Refrigerators The evaluator will utilize the metered data collected from the replaced refrigerators for estimating the energy and demand impacts. If conducted Low-Income Weatherization Program Analysis in Support of Tariff Filing 111- 08/22/05 Case No. PAC-O6- Exhibit 2 customer surveys will be used to verify the presence of new refrigerators. Actual savings will be verified with billing analysis as described below. Savings Analysis Traditionally, "quasi experimental" research design is the most appropriate method for conducting impact evaluations of demand-side management programs. The approach consists of comparing the change in pre- to post- program energy consumption between the participants and a "comparison group of customers who, though eligible, did not participate. By accounting for non-pro gram-related factors that can affect energy use from the pre- to the post-program periods, the approach can provide estimates of "net" program impacts. Census Billing Analysis. A billing analysis will be conducted on all participants that pass the screen for sufficient billing history. These data will be compared to a group oflow-income customers that did not participate in the Program. Princeton Scorekeeping MethodS (PRISM), an established weather- normalizing tool, will be used to calculate each individual customer s annual energy consumption under average weather conditions. Utilizing historical weather data and billing records, PRISM adjusts for the impact of weather variations upon usage during both the pre and post periods. The result is weather-normalized and annualized data that allow for the meaningful interpretation of the true impact of the Program upon energy consumption. The evaluator will use difference-of-means tests to analyze disparities between the participants and non-participant billing data. The evaluator will also analyze the differences between pre and post PRISM- produced set temperatures for assessment of take back. Savings by Agency and Measure Type. Utilizing the estimates from the billing analysis and detailed statistical models, the evaluator will stratify savings by agency and measure. This will provide valuable insight into the Program s operation and overall economic performance. This analysis will provide descriptive statistics on the frequency of installations for specific measures and groups of interrelated measures. It will also provide estimates savings for groups of measures and can be compared to deemed savings to assess possible discrepancies. Additionally, these data will be stratified by In order to produce the most accurate results, PRISM models each participant's pre and post periods separately, generating an individual normalized consumption record for each period. Employing several stages, PRISM utilizes an iterative process to determine the appropriate model (Heating-Only or Heating & Cooling) that best fits the data based on the usage characteristics exhibited by the participant.

Quantify Non-Energy Benefits. If surveys are conducted, the evaluator will estimate non-energy benefits, where applicable. Conduct Cost-Effectiveness Analysis The evaluator will conduct a cost-effectiveness analysis using traditional tools. The analysis will include the standard perspectives (i., utility, ratepayers, participants, and society) and, as much as possible, non-energy and environmental impacts (e., carbon dioxide reduction and reduction in forced mobility). The benefits to Utah Power include the reduction in energy consumption and the Company s avoided costs. Program costs include administration, delivery, and actual payments made to participants. Benefit/cost ratios will be computed from the various perspectives. Management & Reporting The evaluator will deliver a draft and final report of findings. The final report will reflect all the comments made by stakeholders. It will provide a complete description of the relevant evaluation objectives and how they were achieved. The final report is to contain the following elements: Executive Summary Description of the Program, its goals, and objectives Statement of the evaluation goals and objectives Discussion of methodologies Implementation procedures and assumptions for each method Data-collection procedures and methods Sample design and sample attrition Results and their interpretation (demonstrated clearly with charts and tables) Timeline A process evaluation of the Program should be conducted approximately one year after Program implementation to assure that the Program is operating as planned. An impact evaluation should be conducted two years after Program implementation to allow sufficient post-implementation billing data to be available. Low-Income Weatherization Program Analysis in Support of Tariff Filing 111- 08/22/05 Case No. PAC-O6- Exhibit 2 Appendix A. EP A Guidelines Safe Disposal Requirements Under Environmental Protection Agency (EP A) rules, equipment that is typically dismantled on site before disposal (e., retail food refrigeration central residential air conditioning, chillers, and industrial process refrigeration) has to have the refrigerant recovered in accordance with EPA' requirements for servicing. However, equipment that typically enters the waste stream with the charge intact (e., motor vehicle air conditioners household refrigerators and freezers, and room air conditioners) is subject to special safe disposal requirements. Under these requirements, the final person in the disposal chain (e., a scrap metal recycler or landfill owner) is responsible for ensuring that refrigerant is recovered from equipment before the final disposal of the equipment. However, persons "upstream" can remove the refrigerant and provide documentation of its removal to the final person if this is more cost effective. If the final person in the disposal chain (e., a scrap metal recycler or landfill owner) accepts appliances that no longer hold a refrigerant charge, that person is responsible for maintaining a signed statement from whom the appliance is being accepted. The signed statement must include the name and address of the person who recovered the refrigerant, the date that the refrigerant was recovered, or a copy of a contract stating that the refrigerant will be removed prior to delivery. EPA does not mandate a sticker as a form of verification that the refrigerant has been removed prior to disposal of the appliance. Such stickers do not relieve the final disposer of their responsibility to recover any remaining refrigerant in the appliance, unless the sticker contains a signed statement that includes the name and address of the person who recovered the refrigerant and the date on which was recovered. The equipment used to recover refrigerant from appliances prior to their final disposal must meet the same performance standards as equipment used prior to servicing, but it does not need to be tested by a laboratory. This means that self-built equipment is allowed as long as it meets the performance requirements. For MV ACs and MV AC-1ike appliances, the performance requirement is 102 rom of mercury vacuum; for small appliances, the recovery equipment performance requirements are 90% efficiency when the appliance compressor is operational and 80% efficiency when the appliance compressor is not operational. Technician certification is not required for individuals removing refrigerant from appliances in the waste stream.
