Please state your name, business address, and 2 present position with Idaho Power Company ("Idaho Power" or 3 "Company") . 4 A. My name is Riley Maloney. My business address 5 is 1221 West Idaho Street, Boise, Idaho 83702 . I am 6 employed by Idaho Power as a Policy and Strategy Leader in 7 the Regulatory Affairs Department. 8 Q. Please describe your educational background. 9 A. I received a Bachelor of Arts degree in 10 Economics from Boise State University in 2013 . I have also 11 attended "The Basics : Practical Regulatory Training for the 12 Electric Industry, " an electric utility ratemaking course 13 offered through the New Mexico State University' s Center 14 for Public Utilities, "Electric Utility Fundamentals and 15 Insights, " an electric utility course offered by Western 16 Energy Institute, "Electric Rates Advanced Course, " an 17 electric utility ratemaking course offered through Edison 18 Electric Institute, and "Utility Finance and Accounting for 19 Finance Professionals, " a utility-focused finance and 20 accounting course offered through the Financial Accounting 21 Institute . 22 Q. Please describe your work experience with 23 Idaho Power. 24 A. In 2020 I was hired as a Regulatory Analyst Maloney, DI 2 Idaho Power Company 1 in the Company' s Regulatory Affairs Department. My primary 2 responsibilities at the time included supporting activities 3 involving tariff administration and regulatory compliance 4 filings . I also provided regulatory support to the 5 Company' s operations business units to ensure consistent 6 application of the Company' s rules and regulations, 7 authorized by its Commission-approved tariff and in 2023, 8 my responsibilities were expanded to support the Company' s 9 class cost-of-service activities . In April 2025, I was 10 promoted to my current role of Regulatory Policy and 11 Strategy Leader where my responsibilities include 12 overseeing regulatory support and strategic guidance on a 13 variety of topics including integrated resource planning, 14 demand-side management, distribution system planning, and 15 wildfire-related activities . 16 Q. What is the purpose of your testimony in 17 this matter? 18 A. My testimony will first provide a brief 19 regulatory background related to the Operation and 20 Maintenance ("O&M") charges contained in Schedule 72 . I 21 will then explain the Company' s proposed update to Schedule 22 72' s 0&M charges that are requested to be effective January 23 1, 2026 . Maloney, DI 3 Idaho Power Company 1 I . BACKGROUND 2 Q. Please provide an overview of the 3 availability and applicability of Schedule 72 . 4 A. Schedule 72 is available to Sellers owning 5 or operating Qualifying Facilities ("QFs") that sign a 6 Uniform Interconnection Agreement. Service under Schedule 7 72 applies to the construction, operation, maintenance, 8 upgrade, relocation, or removal of transmission and/or 9 distribution lines and equipment necessary to safely 10 interconnect a seller' s generation facility to the 11 Company' s system. 12 Q. When was Schedule 72 established? 13 A. Schedule 72 was initially implemented in a 14 1990 case as the Commission approved the process to 15 facilitate the interconnection of QF generation to Idaho 16 Power' s system, in accordance with the provisions of the 17 Public Utility Regulatory Policies Act of 1978 ("PURPA") . 18 Prior to the establishment of Schedule 72, interconnection 19 requirements for QFs were provided for as part of the Power 20 Purchase Agreement negotiated between the Company and the 21 QF. 22 Q. Please explain the purpose of the O&M charge 23 contained within Schedule 72 . 24 A. When a PURPA project interconnects to the 25 Company' s facilities, the project pays the capital costs of Maloney, DI 4 Idaho Power Company 1 the facilities necessary to connect the project to the 2 Company' s system. Once completed, ownership of these 3 facilities prior to the QF' s interconnection point 4 transfers to the Company, which then assumes responsibility 5 for all ongoing 0&M expenses . The charge within Schedule 72 6 represents a monthly 0&M charge ("O&M Charge") designed to 7 reimburse the Company for the costs, using system averages, 8 associated with operating and maintaining such 9 interconnection facilities . These charges are necessary to 10 ensure the Company' s general body of customers do not 11 shoulder the ongoing 0&M of the facilities caused by the 12 addition of the QF project. 13 Q. How does the 0&M Charge work? 14 A. The 0&M Charge currently has two components : 15 a calculation of a system average monthly 0&M rate and a 16 de-levelization mechanism that lowers the rate in the early 17 years of a project' s life and escalates the rate over a 35- 18 year period. The applicable percentage changes annually on 19 the anniversary of the first energy date of the project in 20 accordance with the 0&M Charge contained within Tables 1 21 and 2 in Schedule 72 . 22 Q. Please explain the range of rates applicable 23 to transmission facilities and distribution facilities . 24 A. Table 1 contains the rates applicable to QF 25 interconnections considered to be at the transmission- Maloney, DI 5 Idaho Power Company 1 level (138-kilovolt ("kV") and 161 kV) , which range from 2 0 .26 percent in year 1 to 1 . 14 percent in year 35 . These 3 charges are equivalent to a 35-year levelized rate of 0 . 40 4 percent . 5 Table 2 contains the rates applicable to QF 6 interconnections considered to be at a distribution-level 7 (below 138 kV) , which range from 0 . 47 percent in year 1 to 8 2 . 11 percent per month in year 35 . These charges are 9 equivalent to a 35-year levelized rate of 0 . 70 percent. 10 Q. When were these charges first implemented? 11 A. The 35-year tables of 0&M charges in 12 Schedule 72 were first implemented in 1992 . The Commission 13 adopted these rates in Case IPC-E-90-20, with an effective 14 date of March 1, 1992 .' 15 Q. How were the rates developed? 16 A. The rates were developed using a formulaic 17 methodology based on actual system O&M costs as a 18 percentage of system plant balances . 19 Q. Have the 0&M Charge monthly rates been 20 updated since 1992? 21 A. Not materially. One modification was made in 22 2016 to incorporate a charge for projects greater than 35 Order No. 24172 Maloney, DI 6 Idaho Power Company 1 years old.2 For all projects 36 years or older, the 0&M 2 Charge applied relies on the levelized rates of 0 . 70 3 percent and 0 . 40 percent for distribution and transmission 4 projects, respectively. 5 Q. Was an 0&M Charge applied to projects that 6 existed before the development of Schedule 72? 7 A. Yes . Prior to the establishment of Schedule 8 72, projects paid the levelized 0 . 70 percent and 0 . 40 9 percent for distribution and transmission projects, 10 respectively, but were not subject to the 35-year table . 11 Instead, the flat rates were embedded into each individual 12 project' s contract. 13 Q. Has the 0&M Charge been the subject of any 14 other proceedings since 1990? 15 A. Yes . In Case No. IPC-E-18-073, several 16 parties submitted a Petition to the Commission, arguing 17 among other things, that the "Commission should modify its 18 existing policy and orders approving of use the current 19 regime for Schedule 72 0&M charges for QFs . "4 In that case, 20 the petitioners argued that Idaho Power should assess only 2 Advice No. 16-04, filed on September 2, 2016, and approved on September 26, 2016 3 IN THE MATTER OF PETITION OF IDAHYDRO, SHOROCK HYDRO, INC. , J.R. SIMPLOT COMPANY, AND RENEWABLE ENERGY COALITION FOR MODIFICATION OF THE 90/110 PERFORMANCE BAND AND CALCULATION OF OPERATION AND MAINTENANCE CHARGES FOR PURPA QUALIFYING FACILITIES 4 Petition, page 9. Maloney, DI 7 Idaho Power Company 1 the actual 0&M costs expended by the Company for each 2 individual QF interconnection. After discovery and 3 discussions among the parties, the Petition in that case 4 was eventually withdrawn and no changes were implemented 5 from the proceedings .5 6 Q. Have the Schedule 72 0&M Charges been at 7 issue in any other cases since IPC-E-18-07? 8 A. Yes . The Company filed a general rate case 9 in 2023 (Case No. IPC-E-23-11) . While the Company had not 10 proposed any modifications to the Schedule 72 0&M Charges 11 as part of its application, in the Settlement Stipulation 12 approved by the Commission in that case, the parties agreed 13 to the following: 14 11 . Generator Interconnection Charges . The 15 monthly operations and maintenance (0&M) charge 16 in Schedule 72, Generator Interconnections to 17 PURPA Qualifying Facility Sellers, will be 18 updated in the future to reflect current 19 operating metrics and assumptions, in 20 conjunction with the informal proceeding 21 described in paragraph 13 (b) below. . . 22 13 . Separate Informal Proceedings . To 23 facilitate further investigation and 24 participation, the Parties agree that : . . . 25 (b) IdaHydro will initiate and meet with Idaho 26 Power to discuss Qualified Facility 0&M charges . 27 Execution of, and agreement to this Stipulation 28 and Settlement is without prejudice to any 29 Parties' ability to bring a separate action 5 On October 17, 2018, Idahohydro, Shorock, Simplot, and REC filed a Notice of Withdrawal of their April 16, 2018 Petition and Idaho Power filed a Notice of Withdrawal of its July 25, 2018, Cross-Petition. Maloney, DI 8 Idaho Power Company 1 before the Commission related to 0&M charges in 2 Schedule 72 .6 3 Q. Have Idaho Power and IdaHydro discussed 0&M 4 charges? 5 A. Yes . Idaho Power has discussed Schedule 72 0&M 6 charges on several occasions with representatives of IdaHydro 7 and discussed the basis for the methodology used to establish 8 the current 0&M Charges in 1990 ("Original Methodology") . 9 Coincident with these discussions, Idaho Power provided Excel 10 workbooks that performed the calculations to allow IdaHydro 11 to develop a more complete understanding of the methodology. 12 Those workbooks also recalculated the equivalent levelized 13 0&M charge rates using historical financial information from 14 several other select years (2015-2017, 2022, 2023) . 15 Q. What was the outcome of that analysis? 16 A. The table below shows a summary of the 17 analyses provided to IdaHydro. Notably, the results across 18 all years reviewed remained relatively consistent, when 19 evaluating 0&M on a levelized basis . Interconnection Level 19897 2015 2016 2017 2022 2023 Transmission 0 . 380 0 . 350 0 . 320 0 . 310 0 . 350 0 . 340 Distribution 0 . 650 0 . 640 0 . 650 0 . 620 0 . 710 0 . 610 20 6 CASE NO. IPC-E-23-11 MOTION FOR APPROVAL OF STIPULATION AND SETTLEMENT In the Matter of the Application of Idaho Power Company for Authority to Increase its Rates and Charges for Electric Service in the State of Idaho and for Associated Regulatory Account Treatment. Page 12 7 The approved Schedule 72 charges of 0.40 and 0.70 percent had been rounded to the nearest tenth of a percent. Maloney, DI 9 Idaho Power Company 1 Q. Has the Company calculated an updated O&M 2 rate that it proposes for this update? 3 A. Yes . Generally relying on the Original 4 Methodology, the Company calculated new rates based on 13- 5 month average plant balances and such plant' s associated 6 0&M expenses, as stated within the Company' s 2024 FERC Form 7 1 . 8 Q. What are the new rates being proposed in 9 this case? 10 A. The Company proposes a monthly 0 . 96 percent 11 rate applied to the original cost of distribution 12 interconnection equipment and a 0 . 28 percent rate applied 13 to the original cost of transmission interconnection 14 equipment. Exhibit No. 1 provides the calculation of these 15 proposed levelized rates . 16 Q. How do these rates compare to the levelized 17 rates currently in effect? 18 A. The levelized distribution rate increases 19 from 0 . 70 percent per month to 0 . 96 percent per month, 20 while the levelized transmission rate decreases from 0 . 40 21 percent per month to 0 . 28 percent per month. 22 Q. What drove the increase to the distribution 23 rate? 24 A. The primary driver of the increase in the 25 proposed distribution 0&M rate is increased distribution Maloney, DI 10 Idaho Power Company I maintenance expenses . Specifically, FERC Account 593 2 "Distribution Maintenance-Overhead Lines" is one of the 3 accounts used in the formula to determine the Distribution 4 0&M Charge. This account includes the costs of vegetation 5 management, among several other costs . The amount in this 6 account in 2024 was approximately $35 . 5 million dollars, 7 compared to approximately $17 . 8 million and $21 . 9 million 8 in 2023 and 2022, respectively. The driver of this increase 9 was largely wildfire-related costs, such as vegetation 10 management expenses and amortization of the Company' s 11 wildfire deferral . 12 Q. You mentioned you generally followed the 13 Original Methodology to develop the proposed rates . What 14 changes to that methodology did you incorporate to develop 15 the proposed rates? 16 A. A couple changes were necessary that apply to 17 both the distribution and transmission rate calculation 18 methodology, as well as other changes specific to the 19 transmission rate' s derivation. 20 First, property taxes are no longer being allocated. 21 The Company' s tax department confirmed that the State of 22 Idaho no longer assesses property taxes on what is 23 considered "contributed property, " which the PURPA 24 interconnection facilities relevant to this case are 25 considered to be. Second, the previous methodology Maloney, DI 11 Idaho Power Company 1 separately calculated an allocation of payroll taxes that 2 were recorded in a distinct FERC account separate from 3 labor expenses . This is no longer necessary due to a change 4 in the way the Company accounts for payroll taxes . Payroll 5 taxes are now allocated directly to the 0&M accounts that 6 contain the associated labor expenses (i .e. , payroll taxes 7 now "follow the labor") . This second change does not impact 8 the results of the calculation, just the presentment when 9 contrasting against the Original Methodology. 10 Q. Are there any other changes to the Original 11 Methodology? 12 A. Yes . For the original calculation of the 13 transmission 0&M rate in 1990, the Company had used a 14 "Transmission Sub-Functionalization" report to determine 15 the proportion of transmission service lines to total 16 transmission investment. The Company discontinued creating 17 this report in approximately the early 2000' s and, as such, 18 now relies upon the proportion of 138 kV and 161 kV line 19 investment for such allocation purposes . Additionally, 20 another modification from the methodology previously relied 21 upon is the exclusion of expenses contained within FERC 22 Account 565 - Transmission of Electricity by Others when 23 determining the 0&M Charge for transmission facilities 24 given these costs are unrelated to those imposed on the 25 Company by PURPA project interconnections . Maloney, DI 12 Idaho Power Company 1 Q. Will these changes impact the results of the 2 Transmission 0&M Charge formula rate calculation? 3 A. Based on the Company' s review of the 1990 4 data, the Company' s revised methodology to determine the 5 proportion of transmission service lines provides similar 6 results . That said, removing expenses contained within FERC 7 Account 565 - Transmission of Electricity by Others does 8 reduce transmission' s 0&M charge. However, as stated above, 9 these expenses are unrelated to those imposed by PURPA 10 project interconnections and therefore should not be 11 recovered through Schedule 72' s O&M charge. 12 Q. Is the Company proposing to continue to 13 apply a non-levelized rate to collect 0&M Charges? 14 A. No . The Company proposes to rely on the 15 levelized rates to collect 0&M going forward. Relying on a 16 levelized collection is similar to how the Company collects 17 0&M associated with its Rule M, Facilities Charge service . 18 Q. Please explain the Company' s proposal to 19 change its collection from a de-levelized rate to a 20 levelized rate. 21 A. The rates that are currently in effect were 22 subjected to a "de-levelization" process, where the rate is 23 lower early in the life of the interconnection equipment 24 and escalated for 35 years using an inflation factor. The 25 Company proposes to remove the de-levelization concept from Maloney, DI 13 Idaho Power Company 1 the rate and instead charge the same calculated average 2 rate each year. 3 Q. Why was the de-levelized rate initially 4 implemented? 5 A. Certain parties to Case IPC-E-90-20 argued 6 that actual maintenance expenses tend to be lower early in 7 the life of the equipment and increase over time, and that 8 de-levelization would more closely match 0&M charge revenue 9 with 0&M expenses . Also, the de-levelization was thought to 10 provide a benefit to PURPA project financing by lowering 11 the 0&M charges in the early years of the project and thus 12 improving project cash flows . 13 Q. What assumptions were relied on for the basis 14 for the de-levelized structure? 15 A. An assumed inflation rate, a discount rate, 16 and the estimated life of the interconnection equipment 17 were all components of the de-levelization calculation. 18 Notably, at that time (early in the implementation of 19 PURPA) , the standard PURPA contract was 35 years, which was 20 the basis for the 35-year horizon . Currently, PURPA 21 contract lengths can range from 2 to 20 years . 22 Q. Why is the Company proposing to remove the de- 23 levelization component? 24 A. For several reasons, the first of which is 25 simplification. De-levelization requires the Company to Maloney, DI 14 Idaho Power Company 1 make and the Commission to approve assumptions about future 2 inflation rates, and the formula requires estimates of 3 interconnection asset lives and PURPA contract lives that 4 are subject to uncertainty. Eliminating the need to 5 develop, monitor, and update these assumptions simplifies 6 the 0&M charge process . Inflation rates that had been 7 historically low for several decades have recently spiked 8 back up to levels not seen since the 1980s . Determining the 9 proper inflation rate to apply to the de-levelization 10 formula is particularly challenging. 11 Second, the Company' s proposal makes the Schedule 72 12 0&M Charge consistent with the Company' s Rule M, Facilities 13 Charges, which also use system average costs . 14 Third, project development under PURPA has now 15 matured compared to the early days of PURPA when the 16 current Schedule 72 0&M charge was first developed. Among 17 other things, contract terms are shorter now (2 years to 20 18 years) as opposed to Idaho' s initial PURPA implementation 19 when contract terms were regularly 35 years . Many early 20 PURPA contracts have also reached the 35+ year time frame 21 and are back to being assessed the levelized rate . Further, 22 recent PURPA development has been focused on hydro and wind 23 projects . The Company has no experience with replacement 24 contracts for these developer-owned resources, which makes Maloney, DI 15 Idaho Power Company 1 it hard to develop assumptions regarding the proper 2 timeframe to use when developing de-levelized rates . 3 Finally, and as discussed in more detail below, the 4 Company proposes to more frequently update its O&M charge 5 percentages, which will negate some of the perceived 6 benefits of de-levelization. 7 Q. How are 0&M Charges treated for ratemaking 8 purposes? 9 A. O&M Charges collected from PURPA projects are 10 treated as a revenue credit when calculating the revenue 11 requirement of Idaho Power' s retail service customers . This 12 revenue credit was last updated as part of the Company' s 13 general rate case filed as Case No. IPC-E-23-13 and totaled 14 approximately $1, 800, 000 for Idaho customers . 15 Q. Has the Company quantified the ratemaking 16 impact of its proposal? 17 A. Yes . If the proposed rates were applied to 18 projects active at the end of 2024, the total annualized 19 amount collected from 0&M Charges would increase by 20 approximately $4, 800 . 21 Q. Has the Company reviewed the impact of its 22 proposed changes on current PURPA projects? 23 A. Yes . The impact to existing projects will be 24 driven by three interrelated factors : (1) what point in 25 time during the 36+-year horizon the project is in, (2) Maloney, DI 16 Idaho Power Company 1 whether the project' s interconnection facilities are 2 transmission or distribution, and (3) the impact of an 3 increase to the average distribution rate and a decrease in 4 the average transmission rate. 5 Overall, when holistically considering the Company' s 6 proposal, of the 121 non-mixed facility Idaho PURPA 7 projects paying an 0&M Charge at the end of 2024 : 45 will 8 be assessed a lower charge (an average decrease of 9 approximately $553 per month) and 76 will be assessed a 10 higher charge (an average increase of approximately $373 11 per month) . For the five Idaho PURPA projects with both 12 transmission and distribution facilities subject to an O&M 13 Charge as of the end of 2024, their monthly charge will, on 14 average, decrease by approximately $623 . 15 Q. How many projects have reached the 36 plus 16 years and reverted back to the flat rate? 17 A. As of the end of 2024, 40 projects have 18 reached the 36 plus years and accordingly have reverted 19 back to the flat rate. 20 Q. Is the Company proposing to periodically 21 update the new formula rates? 22 A. Yes . As noted above, the Company proposes that 23 the 0&M Charges and corresponding revenue credit would be 24 updated during each general rate case, similar to how it 25 updates Rule M, Facilities Charges . Maloney, DI 17 Idaho Power Company 1 Q. If the Company' s proposal is approved, how 2 does the Company propose to handle PURPA projects paying 3 under the existing de-levelized rate mechanism? 4 A. Given the relatively small change in overall 5 revenue, the Company proposes transitioning all PURPA 6 projects to the fixed rates outlined in this case, 7 regardless of where each project is within the existing de- 8 levelized rate table. If its proposal is approved, Idaho 9 Power would implement this change, effective January 1, 10 2026 . 11 Q. Does this conclude your direct testimony in 12 this case? 13 A. Yes, it does . 14 Maloney, DI 18 Idaho Power Company 1 DECLARATION OF RILEY MALONEY 2 I, Riley Maloney, declare under penalty of perjury 3 under the laws of the state of Idaho: 4 1 .
