IDAHO POWER COMPANY
DIRECT TESTIMONY
OF
CONNOR L. ALLEN
1 Q. Please state your name and business address .
2 A. My name is Connor L. Allen. 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 Analyst in the
7 Regulatory Affairs Department.
8 Q. Please describe your educational and pre-Idaho
9 Power employment background.
10 A. In May 2020, I received a Bachelor of Science
11 degree in Economics from the University of Idaho. In May of
12 2022, I earned a Master of Science degree from the
13 University of Idaho in Applied Economics . In September
14 2022, I accepted a role as a Research and Data Analyst for
15 Camoin Associates and served in this capacity until I left
16 Camoin Associates to join Idaho Power in May 2025 . After
17 joining Idaho Power, I attended the electric utility
18 ratemaking course "Practical Regulatory Training for the
19 Electric Industry, " offered through New Mexico State
20 University' s Center for Public Utilities .
21 Q. Please describe your work experience with
22 Idaho Power.
23 A. In 2025, I was hired as a Regulatory Analyst
24 in the Company' s Regulatory Affairs Department. My primary
25 responsibilities include supporting the Company' s class
ALLEN, DI 2
Idaho Power Company
1 cost-of-service activities, developing pricing for special
2 contract customers and other large load pricing analysis,
3 supporting the Company' s annual Fixed Cost Adjustment
4 ("FCA") calculation and serving as the Company witness .
5 Q. What is the purpose of your testimony?
6 A. The purpose of my testimony is to describe the
7 Company' s request to implement its annual FCA rates in
8 conformance with Idaho Public Utilities Commission
9 ("Commission") Order No. 32505 (Case No. IPC-E-11-19) ,
10 which approved the FCA as a permanent rate mechanism for
11 the Residential and Small General Service customers; Order
12 No . 35273 (Case No. IPC-E-21-39) , which approved
13 modification of the FCA to institute separate fixed cost
14 tracking for Residential and Small General Service
15 customers added to the Company' s system; and Order No.
16 36042 (Case No. IPC-E-23-11) , which updated various
17 components of the FCA.
18 Q. What is the Company requesting in this case?
19 A. The Company is seeking authority to collect
20 the 2025 FCA deferral balance of $2, 025, 793 through its
21 proposed 2026-2027 FCA rates . If approved, the 2026-2027
22 FCA rates will increase annual billed revenue for the
23 Residential and Small General Service classes by $5, 117, 270
24 - representing a 0 . 65 percent increase - effective June 1,
25 2026 .
ALLEN, DI 3
Idaho Power Company
1 Q. How is your testimony organized?
2 A. My testimony will discuss three areas related
3 to the FCA mechanism and Schedule 54, Fixed Cost
4 Adjustment. First, I will discuss the need for the FCA
5 itself. Second, I will provide an overview of the FCA
6 mechanics and describe how each component is determined and
7 how the 2025 FCA deferral amount was calculated. Lastly, I
8 will discuss the calculation of the proposed FCA rates to
9 become effective June 1, 2026, remaining in effect until
10 May 31, 2027 .
11 Q. Are you sponsoring any exhibits?
12 A. Yes . I am offering the following exhibits :
Exhibit Description
Exhibit No. 1 2025 FCA Monthly Report
Exhibit No. 2 2025 FCA Calculation
Exhibit No. 3 Monthly Customer Count and Billed Sales
Exhibit No. 4 2025 FCA - Jan 2025 to May 2026
Exhibit No. 5 Rate Determination and Cap
Exhibit No . 6 2025 FCA Bill Impact Summary
13 I . PURPOSE OF THE FIXED COST ADJUSTMENT MECHANISM
14 Q. Why is the FCA mechanism necessary?
15 A. The existing two-part rate design for
16 Residential and Small General Service customers collects a
17 substantial portion of the classes' fixed costs through the
18 volumetric energy rate. The FCA is a true-up mechanism that
ALLEN, DI 4
Idaho Power Company
1 "decouples, " or separates, billed energy sales from revenue
2 in order to remove the financial disincentive that exists
3 when the Company invests in Demand Side Management ("DSM")
4 resources and activities . Under the FCA, rates for
5 Residential Service (Schedules 1, 3, 5, and 6) and Small
6 General Service (Schedules 7 and 8) are adjusted annually
7 to recover or refund the difference between a Commission
8 approved per-customer level of fixed cost recovery and the
9 level of fixed cost recovery that the Company received
10 based upon the actual billed energy sales during the
11 previous calendar year.
12 Q. What level of incremental annual energy
13 efficiency savings was achieved in 2025?
14 A. Idaho Power achieved 153, 099 megawatt-hours
15 ("MWh") of savings system-wide in 2025 . The savings equate
16 to enough energy to power approximately 14, 000 average
17 homes a year in Idaho Power' s service area and exceeded the
18 economic technical achievable potential energy efficiency
19 target set in the Company' s 2023 Integrated Resource Plan
20 for the year 2025 . These energy savings are more
21 particularly described in the 2025 DSM Annual Report filed
22 in Case No. IPC-E-26-05 .
23 Q. Do claimed incremental DSM savings encompass
24 the entirety of energy savings customers experience from
25 Idaho Power' s DSM efforts?
ALLEN, DI 5
Idaho Power Company
1 A. No . First, it is important to recognize that
2 savings claimed in any given year continue to recur in
3 subsequent years through the life of the DSM measure . For
4 example, a measure installed in 2022 with a five-year
5 measure life continues to provide energy savings in 2025,
6 though those savings are not included in the 2025 claimed
7 savings reported in the Company' s 2025 DSM Annual Report.
8 Thus, the full impact of the Company' s DSM efforts is
9 better represented by the cumulative impact of historical
10 claimed savings whose measure life extends through 2025 .
11 Second, the Company promotes customer educational
12 outreach, and awareness activities and engaging in
13 marketing efforts, none of which are quantified or claimed
14 as part of Idaho Power' s annual DSM savings but are likely
15 to result in energy savings experienced by the customer and
16 accruing to Idaho Power' s electric system over time .
17 Q. Has the FCA mechanism been effective at
18 removing the financial disincentive that would otherwise be
19 associated with Idaho Power pursuing all cost-effective
20 energy efficiency?
21 A. Yes . The FCA has been and continues to be an
22 effective mechanism that has positioned the Company to
23 continue to support energy efficiency resources while
24 maintaining a reasonable opportunity to recover its fixed
ALLEN, DI 6
Idaho Power Company
1 costs of serving Residential and Small General Service
2 customers .
3 II . 2025 FCA DEFERRAL
4 Q. Does determination of the 2025 FCA deferral
5 amount include the modification and updates approved by the
6 Commission in Case No. IPC-E-23-11?
7 A. Yes . As part of determining the 2025 FCA
8 deferral, customers added to Idaho Power' s system starting
9 January 1, 2024, are considered "new" and have separate,
10 reduced fixed cost tracking, while the 2023 FCA customer
11 count constitutes the level of "existing" customers whose
12 fixed costs are tracked with then-existing FCA components .
13 These new and existing FCA components are described in more
14 detail later in my testimony.
15 There were three updates to the FCA as a result of
16 the Commission-approved settlement in Case No. IPC-E-23-11 .
17 First, "new" customers were reset to be those customers
18 added starting January 1, 2024 . Second, Schedule 6 and
19 Schedule 8 have separate determination of use per customer
20 ("UPC") , fixed cost per customer ("FCC") , and fixed cost
21 per energy ("FCE") for these customer classes . Third, the
22 UPC and a time-differentiated FCE applied to residential
23 customers taking service under the optional time-of-use
24 offering under Schedule 5 or Schedule 6 .
ALLEN, DI 7
Idaho Power Company
1 Q. How was the existing customer count determined
2 in the calculation of the 2025 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 2025 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 2025 average customers . This method captures
15 customers added starting January 1, 2024, through December
16 31, 2025, 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 2025 FCA
21 deferral includes separate, reduced fixed cost tracking for
22 new customers, the 2025 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 .
ALLEN, DI 8
Idaho Power Company
1 III . FCA DETERMINATION FOR CALENDAR YEAR 2025
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
ALLEN, DI 9
Idaho Power Company
1 recent, applicable rate case. For 2025, the most recent,
2 applicable general rate case was Case No. IPC-E-23-11 .
3 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 .

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
19 negative FCA indicates the Company' s authorized fixed cost
ALLEN, DI 10
Idaho Power Company
1 recovery amount is less than the fixed costs determined to
2 have been recovered through the energy rate and results in
3 a refund to customers .
4 Q. Did the underlying cost basis for the FCC and
5 FCE rates used to determine the 2025 FCA deferral balance
6 change from prior years?
7 A. No. The underlying cost basis for the FCC and
8 FCE rates used to calculate the 2025 FCA deferral balance
9 was based on the level of fixed costs established by the
10 Commission in the Company' s most recent, applicable general
11 rate case (Case No. IPC-E-23-11) and can be found in the
12 Company' s tariff under Schedule 54, Fixed Cost Adjustment
13 effective through December 31, 2025 . FCC-Dist and FCE-Dist
14 rates are based on the same underling rate case data but
15 only represent distribution system costs established as
16 part of the applicable rate case.
17 Q. How is the authorized level of fixed cost
18 recovery derived?
19 A. The authorized level of fixed cost recovery is
20 the product of the applicable FCC and the average number of
21 customers, by new and existing customer, and by class . The
22 Company uses a prorated customer count based on the number
23 of active utility service agreements at the end of each
24 month. This approach applies the same methodology that was
25 used to determine customer counts in Case No. IPC-E-23-11 .
ALLEN, DI 11
Idaho Power Company
1 The annual average customer count is derived by calculating
2 the average of the 12 monthly prorated customer counts .
3 Q. How is the actual level of fixed cost recovery
4 determined?
5 A. In compliance with Order No . 33295, the actual
6 level of fixed cost recovery is the product of the
7 applicable FCE and the actual billed energy sales for the
8 calendar year, measured in kWh.
9 Q. How are billed energy sales allocated between
10 existing and new customers?
11 A. For each customer group, total billed energy
12 sales are divided by average customer count to determine
13 the UPC for the customer group. The count of existing and
14 new customers is multiplied by the respective customer
15 group UPC to allocate the share of total billed energy
16 sales on a pro rata basis between existing and new
17 customers .
18 Q. Does the Company compute a monthly FCA
19 deferral balance?
20 A. Yes . Although the FCA is an annual mechanism
21 that is ultimately calculated and determined using customer
22 counts and billed energy sales data for the entire calendar
23 year, a monthly FCA deferral balance is estimated and
24 recorded in the Company' s accounting records to maintain
25 compliance with Generally Accepted Accounting Principles .
ALLEN, DI 12
Idaho Power Company
1 Since 2009, the Company has reported the estimated monthly
2 FCA deferral balance in the monthly FCA Report provided to
3 the Commission. Exhibit No. 1 is a copy of the monthly FCA
4 Report for calendar year 2025 with year-end information.
5 Q. Is it possible for the reported monthly FCA
6 deferral balance estimate to differ from the annual amount?
7 A. Yes . Because the monthly FCA deferral balance
8 is computed using monthly customer counts while the annual
9 FCA deferral balance is computed using the average customer
10 count for the year, the sum of the monthly calculations may
11 differ from the annual calculation.
12 Q. How is the reported monthly estimate adjusted
13 to align with the authorized annual amount?
14 A. At year-end, once the annual FCA amount is
15 determined, an adjustment is made to the sum of the
16 previously recorded 12 monthly estimates to align with the
17 annual FCA deferral balance. Because the annual customer
18 count is the average of the 12 monthly customer counts, it
19 is not available until year-end.
20 Q. What adjustment was made to the 2025 monthly
21 estimates to translate to the Company' s single year-end
22 2025 FCA deferral balance?
23 A. To align with the annual FCA amount to be
24 recorded in the Company' s 2025 financial records, an upward
25 adjustment of $158, 362 was made for the Residential
ALLEN, DI 13
Idaho Power Company
1 customer classes, reflected as the sum of lines 6, 11, 16,
2 21, 26, and 31 in Column 0 of Exhibit No. 1 . An upward
3 adjustment of $448 was made for the Small General Service
4 customer classes, reflected as the sum of lines 45 and 55,
5 column 0 of Exhibit No. 1 . The total upward adjustment for
6 both customer classes is $158, 811 .
7 Q. What is the total amount of the FCA, not
8 including interest?
9 A. As shown in Exhibit No . 2, the total amount of
10 the FCA for the Residential and Small General Service
11 customer classes, not including interest, is $2, 020, 380 .
12 The calculation of the FCA uses the average annual customer
13 count and the annual billed sales amount, which are
14 included in Exhibit No. 3 . The calculated FCA deferral
15 balance for the Residential customer classes, not including
16 interest, is $2, 115, 578 . This amount can be found in
17 Exhibit No. 1 when summing lines 6, 11, 16, 21, 26, and 31
18 in column P, and in Exhibit No. 2 when summing lines 7, 14,
19 and 34 in column D.
20 The calculated FCA deferral balance for the Small
21 General Service customer classes, not including interest,
22 is $ (95, 197) . This amount can be found in Exhibit No. 1
23 when summing lines 45, 50, 55, and 60 in column P, and in
24 Exhibit No . 2 on lines 41 and 48 in column D.
ALLEN, DI 14
Idaho Power Company
1 Q. What is the total amount of the 2025 FCA,
2 including interest, the Company is requesting to implement
3 in rates on June 1, 2026?
4 A. The total amount of the 2025 FCA the Company
5 is requesting to begin collecting in rates on June 1, 2026,
6 is $2, 025, 793 . 18, reflected on line 72, column X, of
7 Exhibit No. 4 . The FCA for the Residential classes is
8 $2, 125, 276 . 50 as reflected on line 40, column X, of Exhibit
9 No . 4 . The FCA for the Small General Service classes is
10 ($99, 483 . 31) as reflected on line 69, column X, of Exhibit
11 No . 4 . Exhibit No. 4 and Exhibit No. 1 both contain the
12 same information as the FCA Report sent to the Commission
13 each month; however, Exhibit No. 4 calculates interest from
14 January 2025 through May 2026, while Exhibit No. 1 shows
15 the FCA deferral only for the 2025 calendar year.
16 Q. What is the significance of the FCA deferral
17 with respect to the Company' s recovery of its fixed costs?
18 A. Because the FCA deferral is positive, the
19 average UPC based on actual billed sales for the year was
20 lower than the level established in Case No. IPC-E-23-11 . In
21 accordance with the approved mechanism, the Residential and
22 the Small General Service classes will receive a rate
23 adjustment to allow for collecting the under collection of
24 fixed costs that were recovered through actual billed
25 energy charges during the year.

1 IV. CALCULATION OF THE 2026-2027 FCA RATE
2 Q. Please describe the calculation of the FCA
3 rates the Company is proposing to go into effect on June 1,
4 2026 .
5 A. The FCA rates the Company proposes to go into
6 effect on June 1, 2026, were calculated by taking the FCA
7 deferral balances for each of the customer classes
8 described above and dividing by the respective class energy
9 sales forecast for June 1, 2026, through May 31, 2027 . The
10 June 1 through May 31 forecast is the same period that has
11 been used historically and is also used for the Power Cost
12 Adjustment Mechanism.
13 Q. What has the Company determined the forecast
14 energy sales to be for both the Residential and Small
15 General Service classes?
16 A. The Company' s forecasted energy sales are
17 5, 969, 021, 430 kWh for the Residential classes and
18 142, 790, 445 kWh for the Small General Service classes . The
19 forecasted energy sales are found in Exhibit No. 5 .
20 Q. What are the corresponding FCA rates for the
21 Residential and Small General Service classes based on a
22 combined and equal FCA rate change, as defined in the
23 approved mechanism?
24 A. The FCA rate for the Residential classes would
25 be a charge of 0 . 0330 cents per kWh and the corresponding
ALLEN, DI 16
Idaho Power Company
I rate for the Small General Service classes would be a
2 charge of 0 . 0402 cents per kWh. The calculation of these
3 rates is also found in Exhibit No. 5 .
4 On page 9 of Order No. 32505, the Commission ordered
5 that the FCA deferral balance continue to be recovered or
6 refunded equally between the Residential and Small General
7 Service customer classes . Although energy use trends
8 differed between the classes during 2025, the Company
9 under-collected its authorized fixed costs on a combined
10 basis relative to the level established in Case No. IPC-E-
11 23-11 . Accordingly, a rate surcharge is required for both
12 customer classes .
13 Q. What is the difference between the FCA
14 deferral balance currently in amortization and the proposed
15 FCA deferral balance to be collected through the FCA rate?
16 A. In this filing, the Company is proposing to
17 collect rates based on an FCA deferral balance of
18 $2, 025, 793 which is $5, 077, 567 greater than the 2024 FCA
19 deferral balance of ($3, 051, 774) . The 2024 deferral balance
20 was approved in Order No. 36617, issued in Case No. IPC-E-
21 25-11, with rates based on that balance effective for the
22 period June 1, 2025, through May 31, 2026 .
23 Q. Considering the current FCA rates in effect,
24 what is the percentage change in billed revenue as measured
ALLEN, DI 17
Idaho Power Company
1 from total billed amounts currently recovered from
2 Residential and Small General Service classes?
3 A. Because the 2025 FCA deferral balance is
4 greater than the 2024 FCA deferral balance and annual sales
5 for June 2026 through May 31, 2027, are forecast to be
6 higher than the same period in the prior year, the 2026-
7 2027 FCA rates represent an annual increase of $5, 117, 270
8 or 0 . 65 percent, from current billed revenue for the
9 affected customer classes . The percentage change in billed
10 revenue is found in Exhibit No. 6 . This proposed change
11 results in an approximate $0 . 75 increase to the monthly
12 bill of a typical residential customer using 900 kWh per
13 month.
14 Q. How will the Company incorporate the FCA
15 charge for the Residential and Small General Service
16 classes on customers' bills?
17 A. The Company proposes to continue including the
18 FCA with the Fixed Cost Adjustment line item on Residential
19 and Small General Service customers' bills .
20 V. CONCLUSION
21 Q. Please summarize the Company' s request in this
22 filing.
23 A. Idaho Power requests the Commission authorize
24 the Company to implement Fixed Cost Adjustment rates for
25 electric service from June 1, 2026, through May 31, 2027,
ALLEN, DI 18
Idaho Power Company
1 in the amount of 0 . 0330 cents per kWh for the Residential
2 classes, and 0 . 0402 cents per kWh for the Small General
3 Service classes . If approved, the 2026-2027 FCA rates will
4 increase annual billed revenue for the Residential and
5 Small General Service classes by $5, 117, 270 or 0 . 65
6 percent, effective June 1, 2026 .
7 Q. Does this complete your testimony?
8 A. Yes, it does .
