IPC-E-25-11 AUTHORITY TO IMPLEMENT FIXED COST ) ADJUSTMENT (-FCA") RATES FOR ) ELECTRIC SERVICE FROM JUNE 1, ) 2025 THROUGH MAY 31, 2026 . ) IDAHO POWER COMPANY DIRECT TESTIMONY OF GRANT T . ANDERSON 1 Q. Please state your name and business address . 2 A. My name is Grant T . Anderson. My business 3 address is 1221 West Idaho Street, Boise, Idaho 83702 . 4 Q. By whom are you employed and in what capacity? 5 A. I am employed by Idaho Power Company ("Idaho 6 Power" or "Company") as a Regulatory Consultant in the 7 Regulatory Affairs Department. 8 Q. Please describe your educational and pre-Idaho 9 Power employment background. 10 A. In May of 2013, I received a Bachelor of 11 Science degree in Microbiology from Oregon State 12 University. In May of 2015, I earned a Master of Business 13 Administration degree from Boise State University. In March 14 2015, I accepted a role as a Corporate Development Analyst 15 for Albertsons, and in 2017, I was promoted to Corporate 16 Development Manager and served in this capacity until I 17 left Albertsons to join Idaho Power in 2018 . After joining 18 Idaho Power, I attended the electric utility ratemaking 19 course "Practical Regulatory Training for the Electric 20 Industry, " offered through New Mexico State University' s 21 Center for Public Utilities, and the "Utility Finance and 22 Accounting" course. 23 Q. Please describe your work experience with 24 Idaho Power. ANDERSON, DI 2 Idaho Power Company 1 A. In 2018, I was hired as a Regulatory Analyst 2 in the Company' s Regulatory Affairs Department. My primary 3 responsibility as a Regulatory Analyst included supporting 4 the Company' s Commercial and Industrial customer classes' 5 rate design and general support of tariff rules and 6 regulations . In 2021, I was promoted to my current position 7 as a Regulatory Consultant. My responsibilities have 8 expanded to include the development of complex cost-related 9 studies, pricing strategies, and the Company' s class cost- 10 of-service activities, as well as supporting the Company' s 11 annual Fixed Cost Adjustment ("FCA") calculation and 12 serving as the Company witness . 13 Q. What is the purpose of your testimony? 14 A. The purpose of my testimony is to describe the 15 Company' s request to implement its annual FCA rates in 16 conformance with Idaho Public Utilities Commission 17 ("Commission") Order No. 32505 (Case No. IPC-E-11-19) , 18 which approved the FCA as a permanent rate mechanism for 19 the Residential and Small General Service customers; Order 20 No . 35273 (Case No. IPC-E-21-39) , which approved 21 modification of the FCA to institute separate fixed cost 22 tracking for Residential and Small General Service 23 customers added to the Company' s system; and Order No. 24 36042 (Case No. IPC-E-23-11) , which updated various ANDERSON, DI 3 Idaho Power Company 1 components of the FCA in the Company' s most recent 2 applicable general rate case. 3 Q. What is the Company requesting in this case? 4 A. The Company is seeking authority to refund the 5 2024 FCA deferral balance of ($3, 051, 774) through its 6 proposed 2025-2026 FCA rates . If approved, the 2025-2026 7 FCA rates will decrease annual billed revenue for the 8 Residential and Small General Service classes by 9 $40, 657, 141 - representing a 5 . 28 percent decrease - 10 effective June 1, 2025 . 11 Q. How is your testimony organized? 12 A. My testimony will discuss three areas related 13 to the FCA mechanism and Schedule 54, Fixed Cost 14 Adjustment. First, I will discuss the need for the FCA 15 itself. Second, I will provide an overview of the FCA 16 mechanics and describe how each component is determined and 17 how the 2024 FCA deferral amount was calculated. Lastly, I 18 will discuss the calculation of the proposed FCA rates to 19 become effective June 1, 2025, remaining in effect until 20 May 31, 2026 . 21 Q. Are you sponsoring any exhibits? 22 23 24 25 ANDERSON, DI 4 Idaho Power Company 1 A. Yes . I am offering the following exhibits : Exhibit Description Exhibit No. 1 2024 FCA Monthly Report Exhibit No. 2 2024 FCA Calculation Exhibit No. 3 Monthly Customer Count and Billed Sales Exhibit No. 4 2024 FCA - Jan 2024 to May 2025 Exhibit No. 5 Rate Determination and Cap Exhibit No . 6 2024 FCA Bill Impact Summary 2 I . PURPOSE OF THE FIXED COST ADJUSTMENT MECHANISM 3 Q. Why is the FCA mechanism necessary? 4 A. The existing two-part rate design for 5 Residential and Small General Service customers collects a 6 substantial portion of the classes' fixed costs through the 7 volumetric energy rate. The FCA is a true-up mechanism that 8 "decouples, " or separates, billed energy sales from revenue 9 in order to remove the financial disincentive that exists 10 when the Company invests in Demand Side Management ("DSM") 11 resources and activities . Under the FCA, rates for 12 Residential Service (Schedules 1, 3, 5, and 6) and Small 13 General Service (Schedules 7 and 8) are adjusted annually 14 to recover or refund the difference between a Commission 15 approved per-customer level of fixed cost recovery and the 16 level of fixed cost recovery that the Company received ANDERSON, DI 5 Idaho Power Company 1 based upon the actual billed energy sales during the 2 previous calendar year . 3 Q. What level of incremental annual energy 4 efficiency savings was achieved in 2024? 5 A. Idaho Power achieved 143, 599 megawatt-hours 6 ("MWh") of savings system-wide, which is enough energy to 7 power approximately 12, 600 average homes a year in Idaho 8 Power' s service area and exceeded the economic technical 9 achievable potential energy efficiency target set in the 10 Company' s 2023 Integrated Resource Plan for the year 2024 . 11 These energy savings are more particularly described in the 12 2024 DSM Annual Report filed in Case No. IPC-E-25-12 . 13 Q. Do claimed incremental DSM savings encompass 14 the entirety of energy savings customers experience from 15 Idaho Power' s DSM efforts? 16 A. No. First, it is important to recognize that 17 savings claimed in any given year continue to recur in 18 subsequent years through the life of the DSM measure . For 19 example, a measure installed in 2021 with a five-year 20 measure life continues to provide energy savings in 2024, 21 though those savings are not included in the 2024 claimed 22 savings reported in the Company' s 2024 DSM Annual Report. 23 Thus, the full impact of the Company' s DSM efforts is 24 better represented by the cumulative impact of historical 25 claimed savings whose measure life extends through 2024 . ANDERSON, DI 6 Idaho Power Company 1 Second, the Company promotes customer educational, 2 outreach, and awareness activities as well as promoting 3 codes and standards and engaging in marketing efforts, none 4 of which are quantified or claimed as part of Idaho Power' s 5 annual DSM savings but are likely to result in energy 6 savings experienced by the customer and accruing to Idaho 7 Power' s electric system over time. 8 Q. Has the FCA mechanism been effective at 9 removing the financial disincentive that would otherwise be 10 associated with Idaho Power pursuing all cost-effective 11 energy efficiency? 12 A. Yes . The FCA has been and continues to be an 13 effective mechanism that has positioned the Company to 14 continue to support energy efficiency resources while 15 maintaining a reasonable opportunity to recover its fixed 16 costs of serving Residential and Small General Service 17 customers . 18 II . 2024 FCA DEFERRAL 19 Q. Does determination of the 2024 FCA deferral 20 amount include the modification and updates approved by the 21 Commission in Case Nos . IPC-E-21-39 and IPC-E-23-11? 22 A. Yes . As part of determining the 2024 FCA 23 deferral, customers added to Idaho Power' s system starting 24 January 1, 2024, are considered "new" and have separate, 25 reduced fixed cost tracking, while the 2023 FCA customer ANDERSON, DI 7 Idaho Power Company 1 count constitutes the level of "existing" customers whose 2 fixed costs are tracked with then-existing FCA components . 3 These new and existing FCA components are described in more 4 detail later in my testimony. 5 There were three updates to the FCA as a result of 6 the Commission-approved settlement in the Company' s most 7 recent applicable general rate case, Case No. IPC-E-23-11 . 8 First, the fixed cost per customer ("FCC") and fixed cost 9 per energy rate ("FCE") rates were reset based on the 10 results of Case No. IPC-E-23-11 and "new" customers were 11 also reset to be those customers added starting January 1, 12 2024 . Second, Schedule 6 and Schedule 8 have separate 13 determination of use per customer ("UPC") , FCC, and FCE for 14 these customer classes . Third, the UPC and a time- 15 differentiated FCE applied to residential customers taking 16 service under the optional time-of-use service offering 17 under Schedule 5 or Schedule 6 . 18 Q. Does the 2024 FCA deferral include any other 19 modifications? 20 A. Yes . In compliance with Order No . 36048 issued 21 in Case No . IPC-E-23-14, the 2024 FCA deferral includes a 22 one-time adjustment to recover the conversion of 23 accumulated kWh credits into a financial credit for 24 residential and small general service customers ("One-Time 25 Net Billing Adjustment") . ANDERSON, DI 8 Idaho Power Company 1 Q. How was the existing customer count determined 2 in the calculation of the 2024 FCA deferral? 3 A. Consistent with the method approved by the 4 Commission in Order No . 35273, the existing customer count 5 was set at the 2023 average number of customers . The 6 existing customer count is updated when rates go into 7 effect following the Company' s most recent, applicable 8 general rate case. 9 Q. How was the new customer count determined in 10 the calculation of the 2024 FCA deferral? 11 A. Because the FCA is an annual mechanism based 12 on average customers for the entire year, new customers 13 were determined as the difference between 2023 average 14 customers and 2024 average customers . This method captures 15 customers added starting January 1, 2024, through December 16 31, 2024, to determine the annual average incremental or 17 "new" customer count. 18 Q. Is there a difference in FCA rates to recover 19 the FCA deferral between existing and new customers? 20 A. No. While determination of the 2024 FCA 21 deferral includes separate, reduced fixed cost tracking for 22 new customers, the 2024 FCA deferral is recovered through a 23 single FCA rate applicable to all Residential customers, 24 new and existing, and a single FCA rate applicable to all 25 Small General Service customers . ANDERSON, DI 9 Idaho Power Company 1 III . FCA DETERMINATION FOR CALENDAR YEAR 2024 2 Q. Please describe the FCA mechanism components 3 and how they are calculated. 4 A. For both the Residential and Small General 5 Service classes, the FCA mechanism is the same . The general 6 formula used to determine the FCA amount is : 7 FCA = (CUST X FCC) - (ACTUAL X FCE) 8 Where : 9 FCA = Fixed Cost Adjustment; 10 CUST = Average Number of Customers, by class; 11 FCC = Fixed Cost per Customer rate, by class; 12 ACTUAL = Actual Billed kilowatt-hours ("kWh") 13 Energy Sales, by class; and 14 FCE = Fixed Cost per Energy rate, by class . 15 The FCA amount is the difference between the 16 Company' s level of "authorized fixed cost recovery" (CUST X 17 FCC) and the level of "actual fixed cost recovery" (ACTUAL 18 X FCE) . The FCC and FCE are bifurcated for new and existing 19 customers, with new customer components labeled as "FCC- 20 Dist" and "FCE-Dist. " 21 Q. What is the difference in fixed cost tracking 22 between new and existing customers, and what is the basis 23 for those costs? 24 A. For both new and existing customers, the basis 25 for fixed cost tracking is the same, the Company' s most ANDERSON, DI 10 Idaho Power Company 1 recent, applicable general rate case . For 2024, the most 2 recent, applicable general rate case was Case No. IPC-E-23- 3 ll . Existing customer FCC and FCE represent fixed costs 4 associated with the Company' s generation-, transmission-, 5 and distribution-related system components . Starting with 6 the 2024 deferral, for new customers only, the 7 distribution-related system cost components are tracked by 8 the FCA. Table 1 lists the FCA cost components for new and 9 existing customers . 10 Table 1 11 FCA Components - Existing and New Customers Sch FCC FCE FCC-DIST FCE-DIST Line Tariff Schedule No. $/Cust./Yr.) ($/kWh) ($/Cust./Yr. $/kWh 1 Residential 1 &3 $739.20 $0.067098 $287.96 $0.026138 2 Residential TOU: SONP 5 $0.175878 $0.083169 3 Residential TOU: SMP 5 $0.087941 $0.041586 4 Residential TOU: SOFP 5 $739.20 $0.043970 $287.96 $0.020792 5 Residential TOU: NSONP 5 $0.085198 $0.029266 6 Residential TOU: NSOFP 5 $0.056798 $0.019511 7 Residential On-Site Gen 6 $654.72 $0.070780 $304.20 $0.032886 8 Small General 7 $174.96 $0.038463 $24.02 $0.005282 9 Small General On-Site Gen 8 $221.61 $0.052308 $63.33 $0.014949 Note:SONP=Summer On-Peak;SMP=Summer Mid-Peak;SOFP=Summer Off-Peak; NSONP=Non-Summer On-Peak;NSOFP=Non-Summer Off-Peak 12 Q. Can the FCA deferral balance be either 13 positive or negative? 14 A. Yes . A positive FCA indicates the Company' s 15 authorized level of fixed cost recovery is greater than the 16 level of fixed costs recovered through the energy rate, 17 which occurs when energy UPC has decreased from when the 18 FCA components were established. In a similar fashion, a ANDERSON, DI 11 Idaho Power Company 1 negative FCA indicates the Company' s authorized fixed cost 2 recovery amount is less than the fixed costs determined to 3 have been recovered through the energy rate and results in 4 a refund to customers . 5 Q. Did the underlying cost basis for the FCC and 6 FCE rates used to determine the 2024 FCA deferral balance 7 change from prior years? 8 A. Yes . The underlying cost basis for the FCC and 9 FCE rates used to calculate the 2024 FCA deferral balance 10 was based on the level of fixed costs established by the 11 Commission in the Company' s most recent, applicable general 12 rate case (Case No . IPC-E-23-11) and can be found in the 13 Company' s tariff under Schedule 54, Fixed Cost Adjustment 14 effective through December 31, 2024 . FCC-Dist and FCE-Dist 15 rates are based on the same underling general rate case 16 data but only represent distribution system costs 17 established as part of the applicable general rate case . 18 Q. How is the authorized level of fixed cost 19 recovery derived? 20 A. The authorized level of fixed cost recovery is 21 the product of the applicable FCC and the average number of 22 customers, by new and existing customer, and by class . The 23 Company uses a prorated customer count based on the number 24 of active utility service agreements at the end of each 25 month. This approach applies the same methodology that was ANDERSON, DI 12 Idaho Power Company 1 used to determine customer counts in Case No. IPC-E-23-11 . 2 The annual average customer count is derived by calculating 3 the average of the 12 monthly prorated customer counts . 4 Q. How is the actual level of fixed cost recovery 5 determined? 6 A. In compliance with Order No. 33295, the actual 7 level of fixed cost recovery is the product of the 8 applicable FCE and the actual billed energy sales for the 9 calendar year, measured in kWh. 10 Q. How are billed energy sales allocated between 11 existing and new customers? 12 A. For each customer group, total billed energy 13 sales are divided by average customer count to determine 14 the UPC for the customer group. The count of existing and 15 new customers is multiplied by the respective customer 16 group UPC to allocate the share of total billed energy 17 sales on a pro rata basis between existing and new 18 customers . 19 Q. Does the Company compute a monthly FCA 20 deferral balance? 21 A. Yes . Although the FCA is an annual mechanism 22 that is ultimately calculated and determined using customer 23 counts and billed energy sales data for the entire calendar 24 year, a monthly FCA deferral balance is estimated and 25 recorded in the Company' s accounting records to maintain ANDERSON, DI 13 Idaho Power Company 1 compliance with Generally Accepted Accounting Principles . 2 Since 2009, the Company has reported the estimated monthly 3 FCA deferral balance in the monthly FCA Report provided to 4 the Commission. Exhibit No. 1 is a copy of the monthly FCA 5 Report for calendar year 2024 with year-end information. 6 Q. Is it possible for the reported monthly FCA 7 deferral balance estimate to differ from the annual amount? 8 A. Yes . Because the monthly FCA deferral balance 9 is computed using monthly customer counts while the annual 10 FCA deferral balance is computed using the average customer 11 count for the year, the sum of the monthly calculations may 12 differ from the annual calculation. 13 Q. How is the reported monthly estimate adjusted 14 to align with the authorized annual amount? 15 A. At year-end, once the annual FCA amount is 16 determined, an adjustment is made to the sum of the 17 previously recorded 12 monthly estimates to align with the 18 annual FCA deferral balance. Because the annual customer 19 count is the average of the 12 monthly customer counts, it 20 is not available until year-end. 21 Q. What adjustment was made to the 2024 monthly 22 estimates to translate to the Company' s single year-end 23 2024 FCA deferral balance? 24 A. To align with the annual FCA amount to be 25 recorded in the Company' s 2024 financial records, an upward ANDERSON, DI 14 Idaho Power Company 1 adjustment of $146, 818 was made for the Residential 2 customer classes, reflected as the sum of lines 6, 11, 16, 3 21, 26, and 31 in Column 0 of Exhibit No. 1 . A downward 4 adjustment of $1, 615 was made for the Small General Service 5 customer classes, reflected as the sum of lines 45 and 55, 6 column 0 of Exhibit No. 1 . The total upward adjustment for 7 both customer classes is $145, 203 . 8 Q. What is the total amount of the FCA, not 9 including interest and the One-Time Net Billing Adjustment? 10 A. As shown in Exhibit No. 2, the total amount of 11 the FCA for the Residential and Small General Service 12 customer classes, not including interest and one-time 13 adjustment, is $ (3, 047, 200) . The calculation of the FCA 14 uses the average annual customer count and the annual 15 billed sales amount, which are included in Exhibit No. 3 . 16 The calculated FCA deferral balance for the Residential 17 customer classes, not including interest and the one-time 18 adjustment, is $ (2, 934, 454) . This amount can be found in 19 Exhibit No. 1 when summing lines 6, 11, 16, 21, 26, and 31 20 in column P, and in Exhibit No. 2 when summing lines 7, 14, 21 and 34 in column D. 22 The calculated FCA deferral balance for the Small 23 General Service customer classes, not including interest 24 and the one-time adjustment, is $ (112, 746) . This amount can 25 be found in Exhibit No. 1 when summing lines 45, 50, 55, ANDERSON, DI 15 Idaho Power Company 1 and 60 in column P, and in Exhibit No. 2 on lines 41 and 48 2 in column D. 3 Q. What is the total amount of the 2024 FCA, 4 including interest, the Company is requesting to implement 5 in rates on June 1, 2025? 6 A. The total amount of the 2024 FCA the Company 7 is requesting to begin refunding in rates on June 1, 2025, 8 is ($3, 051, 774) ($3, 051, 774) , reflected on line 72, column 9 X, of Exhibit No. 4 . The FCA for the Residential classes is 10 ($2, 936, 820 . 93) as reflected on line 40, column X, of 11 Exhibit No. 4 . The FCA for the Small General Service 12 classes is ($114, 953 . 11) as reflected on line 69, column X, 13 of Exhibit No. 4 . Exhibit No. 4 and Exhibit No. 1 both 14 contain the same information as the FCA Report sent to the 15 Commission each month; however, Exhibit No. 4 calculates 16 interest from January 2024 through May 2025, and the One- 17 Time Net Billing Adjustment, while Exhibit No. 1 shows the 18 FCA deferral only for the 2024 calendar year. 19 Q. What is the total amount of the One-Time Net 20 Billing Adjustment for the conversion of kWh credits to 21 financial credits included in the 2024 FCA deferral? 22 A. The total amount of the One-Time Net Billing 23 Adjustment is $74, 442 . 48, reflected on line 72, column V, 24 of Exhibit No. 4 . The one-time adjustment for the 25 Residential classes is $73, 461 . 03 as reflected on line 40, ANDERSON, DI 16 Idaho Power Company 1 column V, of Exhibit No. 4 . The one-time adjustment for the 2 Small General Service classes is $981 . 45 as reflected on 3 line 69, column V, of Exhibit No. 4 . 4 Q. What is the significance of the FCA deferral 5 with respect to the Company' s recovery of its fixed costs? 6 A. Because the Residential and Small General 7 Service FCAs are negative numbers, the average UPC based on 8 actual billed sales for the year were higher than the level 9 established in Case No. IPC-E-23-11 for both Residential 10 and Small General Service customer classes . In accordance 11 with the approved mechanism, the Residential and Small 12 General Service classes will receive a rate adjustment to 13 allow for refunding the over collection of fixed costs that 14 were recovered through actual billed energy charges during 15 the year. 16 IV. CALCULATION OF THE 2025-2026 FCA RATE 17 Q. Please describe the calculation of the FCA 18 rates the Company is proposing to go into effect on June 1, 19 2025 . 20 A. The FCA rates the Company proposes to go into 21 effect on June 1, 2025, were calculated by taking the FCA 22 deferral balances for each of the customer classes 23 described above and dividing by the respective class energy 24 sales forecast for June 1, 2025, through May 31, 2026 . The 25 June 1 through May 31 forecast is the same period that has ANDERSON, DI 17 Idaho Power Company 1 been used historically and is also used for the Power Cost 2 Adjustment mechanism. 3 Q. What has the Company determined the forecast 4 energy sales to be for both the Residential and Small 5 General Service classes? 6 A. The Company' s forecasted energy sales are 7 5, 897, 269, 908 kWh for the Residential classes and 8 140, 694, 846 kWh for the Small General Service classes . The 9 forecasted energy sales are found in Exhibit No. 5 . 10 Q. What are the corresponding FCA rates for the 11 Residential and Small General Service classes based on a 12 combined and equal FCA rate change, as defined in the 13 approved mechanism? 14 A. The FCA rate for the Residential classes would 15 be a credit of 0 . 0503 cents per kWh and the corresponding 16 rate for the Small General Service classes would be a 17 credit of 0 . 0614 cents per kWh. The calculation of these 18 rates is also found in Exhibit No . 5 . 19 On page 9 of Order No. 32505, the Commission ordered 20 that the FCA deferral balance will continue to be recovered 21 or refunded equally between the Residential and Small 22 General Service customer classes . Because the Residential 23 and Small General Service classes increased their energy 24 consumption per customer such that the Company over- 25 collected its authorized level of fixed costs as ANDERSON, DI 18 Idaho Power Company 1 established in Case No. IPC-E-23-11, each class requires a 2 rate reduction. 3 Q. What is the difference between the FCA 4 deferral balance currently in amortization and the proposed 5 FCA deferral balance to be collected through the FCA rate? 6 A. In this filing, the Company is proposing to 7 credit rates based on an FCA deferral balance of 8 $ (3, 051, 774) which is $39, 833, 585 less than the 2023 FCA 9 deferral balance of $36, 781, 811 . The 2023 deferral balance 10 was approved in Order No. 36194, issued in Case No. IPC-E- 11 24-10, with rates based on that balance effective for the 12 period June 1, 2024, through May 31, 2025 . 13 Q. Considering the current FCA rates in effect, 14 what is the percentage change in billed revenue as measured 15 from total billed amounts currently recovered from 16 Residential and Small General Service classes? 17 A. Because the 2024 FCA deferral balance is less 18 than the 2023 FCA deferral balance and annual sales for 19 June 2025 through May 31, 2026, are forecast to be slightly 20 higher than the same period in the prior year, the 2025- 21 2026 FCA rates represent an annual decrease of $40, 657, 141 22 or 5 .28 percent, from current billed revenue for the 23 affected customer classes . The percentage change in billed 24 revenue is found in Exhibit No. 6 . This proposed change 25 results in an approximate $6 . 35 decrease to the monthly ANDERSON, DI 19 Idaho Power Company 1 bill of a typical residential customer using 950 kWh per 2 month. 3 Q. How will the Company incorporate the FCA 4 credit for the Residential and Small General Service 5 classes on customers' bills? 6 A. The Company proposes to continue including the 7 FCA with the Fixed Cost Adjustment line item on Residential 8 and Small General Service customers' bills . 9 V. CONCLUSION 10 Q. Please summarize the Company' s request in this 11 filing. 12 A. Idaho Power requests the Commission authorize 13 the Company to implement Fixed Cost Adjustment credit for 14 electric service from June 1, 2025, through May 31, 2026, 15 in the amount of 0 . 0503 cents per kWh for the Residential 16 classes, and 0 . 0614 cents per kWh for the Small General 17 Service classes . If approved, the 2025-2026 FCA rates will 18 decrease annual billed revenue for the Residential and 19 Small General Service classes of $40, 657, 141 or 5 . 28 20 percent, effective June 1, 2025 . 21 Q. Does this complete your testimony? 22 A. Yes, it does . 23 ANDERSON, DI 20 Idaho Power Company 1 DECLARATION OF GRANT T. ANDERSON 2 I, Grant T .
