19 Q. Please describe your work experience with
20 Idaho Power.
21 A. In September 2021, 1 accepted a position at
22 Idaho Power as a Regulatory Analyst in the Regulatory
23 Affairs Department. In October 2023, I was promoted to
24 Senior Regulatory Analyst . As a Senior Regulatory Analyst,
25 I am responsible for running the AURORA model ("AURORA") ,
BRADY, DI 1
Idaho Power Company

1 an hourly economic dispatch model, to calculate net power
2 supply expenses ("NPSE") . AURORA is used for ratemaking
3 purposes, as well as in the determination of the marginal
4 cost of energy used in the Company' s marginal cost
5 analyses . My duties also include providing analytical
6 support for other regulatory activities within the
7 Regulatory Affairs Department.
8 Q. What is the purpose of your testimony in this
9 matter?
10 A. The purpose of my testimony is to discuss the
11 derivation of the Company' s 2025 retail revenues used for
12 the 2025 test year and present the quantification of the
13 2025 normalized or "base level" net power supply expenses
14 ("2025 Base Level NPSE") and to inform the Commission of
15 the necessary reduction to the rates contained in Schedule
16 55, Power Cost Adjustment ("PCA") resulting from the
17 proposed 2025 Base Level NPSE update .
18 I . 2025 TEST YEAR RETAIL REVENUE DERIVATION
19 Q. What methodology was used to determine test
20 year retail revenues?
21 A. Generally speaking, the Company' s retail
22 revenues are derived by applying base rates to test year
23 billing components . The billing components are derived by
24 applying historical relationships to the Company' s test
25 year customer and kilowatt-hour ("kWh") sales .
BRADY, DI 2
Idaho Power Company

1 Q. Was the 2025 test year retail sales revenue
2 developed using the same methodology applied in the
3 Company' s last general rate case?
4 A. Yes . The 2025 test year retail sales revenue
5 was developed using the same methodology applied in the
6 Company' s 2023 general rate case, Case No. IPC-E-23-11
7 ("2023 General Rate Case") .
8 Q. Please describe the test year customer and kWh
9 sales that serve as the basis for the 2025 test year retail
10 revenues .
11 A. The 2025 test year customer and kWh sales
12 consist of class customer counts and total kWh sales
13 estimates for each month of the test period. It is prepared
14 by the Company' s Load Research and Forecasting Department
15 and is further described in workpapers filed by Company
16 Witness Mr. Matthew T . Larkin.
17 Q. How were the 2025 test year kWh sales further
18 segmented into the class-specific energy-related billing
19 components?
20 A. The first step in deriving energy-related
21 billing components for the test year is to develop factors
22 based on the most current complete calendar year of
23 available historical data, which in this case is 2024 .
24 These historical factors represent the percentage of total
25 kWh billed in each tier level of a class' s rate structure.
BRADY, DI 3
Idaho Power Company

1 To illustrate, Residential Service customers taking
2 service under Schedule 1 are billed according to a three-
3 tiered structure with seasonal rate differentiation. Using
4 the historical month of June 2024 as an example, actual
5 tiered usage was recorded at the following levels for
6 Schedule 1 customers in the Idaho jurisdiction:
7 Table 1
8 2024 Actual Tiered Usage
Table 1 2024 Actual Tiered Usage'
June 2024 Schedule 1
Usage Tier Billing Components
Summer, 0-800 kWh 125, 996, 114
Summer, 801-2000 kWh 35, 979, 185
Summer, Over 2000 kWh 4, 541, 980
Non-Summer, 0-800 kWh 164, 876, 784
Non-Summer, 801-2000 kWh 43, 677, 552
Non-Summer, Over 2000 kWh 6, 453, 058
Total Schedule 1 kWh Usage 381, 524, 673
9 Based on the data above, historical factors for
10 Schedule 1 customers for the month of June were calculated as
11 shown in Table 2 .

Non-Summer, 801-2000 kWh 110
Non-Summer, Over 2000 kWh 20
Total Schedule 1 1000
3 This process is used to develop historical factors
4 for all rate classes with tiered structures . Once a complete
5 set of monthly factors has been developed for each applicable
6 rate class, they are applied to monthly test year kWh totals
7 to derive the energy-related billing components that align
8 with each class' s current rate structure . Continuing with the
9 illustration of Schedule 1 customers, Table 3 demonstrates
10 the final step in determining test year energy-related
11 billing components .

3 Q. How are demand-related billing components
4 derived based on test year kWh sales?
5 A. The demand-related billing components consist
6 of billing demand and basic load capacity ("BLC") by month
7 for each rate class . Both billing demand and BLC totals are
8 calculated by applying four-year average load factors to
9 each month of test year kWh sales . Historical data from the
10 most currently available four calendar years is used to
11 derive an average load factor by month for each rate class .
12 These average factors are then applied to monthly kWh sales
13 figures to determine total billing demand and BLC by class
14 for each month of the test period. Once monthly totals have
BRADY, DI 6
Idaho Power Company

1 been developed, they are divided into the appropriate
2 tiered rate structure (if applicable) utilizing historical
3 factors in the same manner as kWh charges .
4 Q. How are customer-related billing components
5 derived based on test year customer counts?
6 A. The primary customer-related billing
7 component in test year retail revenues is the service
8 charge . Because the customer data reflects the expected
9 number of customers under active Utility Service Agreements
10 ("USAs") at the end of each month, this data must be
11 converted to reflect the expected number of service charges
12 received throughout the corresponding month. To convert the
13 USA count to an expected service charge count, historical
14 factors are developed reflecting the relationship between
15 the number of USAs at the end of each historical month and
16 the number of service charges received during the
17 corresponding month. These factors are then applied to the
18 monthly customer data to develop expected service charges
19 by rate class for each month of the test year.
20 Q. How are the 2025 test year retail revenues
21 calculated once test year billing components have been
22 developed?
23 A. Once the billing components have been
24 developed by rate class, base rates are applied to the test
BRADY, DI 7
Idaho Power Company

1 year values to derive monthly revenue estimates for each
2 rate class .
3 Q. What base rates did the Company apply to the
4 test year values to derive the monthly revenue estimates?
5 A. To reflect base rates expected to be in place
6 at the end of the test year, the base rates used to derive
7 the monthly revenue estimates are from the Company' s filing
8 to increase rates to recover costs associated with the
9 Hells Canyon Complex relicensing project, effective June 1,
10 2025, Case No . IPC-E-25-13 .
11 Q. How are customers taking service under a
12 marginal cost-based rate incorporated into the 2025 test
13 year retail revenues?
14 A. Because marginal cost-priced energy sales are
15 included in the Company' s PCA filing as an offset to NPSE,
16 they are excluded from the 2025 test year retail revenues .
17 However, test year revenue from customer-related and
18 demand-related billing components from marginal cost-priced
19 customers are included in the 2025 test year retail
20 revenues . Special contract customer Lamb Weston, Inc. , is
21 the only customer taking service under a marginal cost-
22 based rate in the 2025 test year pursuant to Schedule 34 .
23 Q. How are Schedule 62, Clean Energy Your Way
24 ("CEYW") - Construction customers accounted for in the 2025
25 test year retail revenues?
BRADY, DI 8
Idaho Power Company

1 A. The 2025 test year retail revenues for CEYW -
2 Construction customers are determined based on the billing
3 structure outlined in Schedule 62 and the respective
4 special contract. This includes customer and demand-related
5 billing components, energy-related charges for the energy
6 supplied by Idaho Power (which is net of the energy
7 supplied by the renewable resource facility) , and the fixed
8 cost-related component for the energy supplied by the
9 renewable resource facility that offsets hourly consumption
10 at the customer' s meter.
11 Q. How are revenues from Schedule 33, Brisbie,
12 LLC. ("Brisbie") incorporated into the 2025 test year
13 retail revenues?
14 A. At the direction of Mr. Larkin, the minimum
15 charges associated with Brisbie' s special contract, which
16 became effective March 2025, are reflected in 2025 test
17 year retail revenues for the entire 12-month period.2
18 Q. Have you prepared any exhibits that detail the
19 calculations that were made to determine the Company' s 2025
20 test year retail revenues?
21 A. Yes . Exhibit No. 22 provides a summary of
22 2025 test year retail revenues, and Exhibit No. 23 details
23 the calculations that were made to determine these
24 revenues . Input data used in the calculations can be found

2 22, the Company' s 2025 Idaho jurisdictional retail sales
3 revenues are determined to be $1 . 47 billion.
4 II . 2025 BASE NET POWER SUPPLY EXPENSES
5 Q. How is this section of your testimony
6 organized?
7 A. First, I provide an overview of the
8 Commission-approved methodology for quantifying base level
9 NPSE . Next, I describe the update to base level NPSE that
10 occurred in 2023 ("2023 Base Level NPSE") . Lastly, I
11 describe the quantification of the Company' s 2025 Base
12 Level NPSE .
13 Q. How has the Commission historically reviewed
14 and approved Idaho Power' s quantification of normal base
15 NPSE?
16 A. Due to the high variability of power supply
17 expenses, the Commission has historically approved a
18 normalized power supply expense value for setting base
19 rates . The Company has utilized the AURORA model to provide
20 the Commission with a snapshot of "normal" expectations for
21 base NPSE for a given test year.
22 Q. Please define the term "base NPSE" as the
23 Company and Commission have used the term historically.
24 A. The Company and Commission have historically
25 defined the term "base NPSE" as the sum of fuel expenses
BRADY, DI 10
Idaho Power Company

1 (Federal Energy Regulatory Commission ["FERC"] Accounts 501
2 and 547) and purchased power expenses (FERC Account 555) ,
3 including purchases from qualifying facilities under the
4 Public Utility Regulatory Policies Act of 1978 ("PURPA")
5 and power purchase agreements ("PPA") , minus surplus sales
6 revenues (FERC Account 447) . The AURORA model is used to
7 quantify base NPSE components related to fuel, short-term
8 market purchases, and surplus sales, while PURPA and PPA
9 expenses are quantified outside of AURORA.3
10 Q. Does the Company include any other categories
11 of expense or revenue in the base level NPSE used for PCA
12 computations?
13 A. Yes . In addition to the expense and revenue
14 categories described above, the base level NPSE included in
15 the Company' s PCA computations also includes financial
16 payments made by Idaho Power to offset transmission losses
17 associated with market purchases (FERC Account 555) , third-
18 party transmission expense required to bring market
19 purchases to the Company' s border (FERC Account 565) , water
20 for power expense (FERC Account 536) , demand response
21 ("DR") incentives (FERC Account 555) , and transmission loss
22 revenue (FERC Account 447) .
3 Energy from PURPA and PPA projects are incorporated into the AURORA
model as must-take resources.
BRADY, DI 11
Idaho Power Company

1 Q. Is the Company proposing to include any new
2 categories of expense or revenue in the base level NPSE
3 used for PCA computations?
4 A. Yes . At the direction of Mr. Larkin, I have
5 included an additional component, FERC Account 577 . 4
6 (energy storage rents) , in the 2025 Base Level NPSE, in
7 order to collect expenses associated with the Kuna Battery
8 Energy Storage System ("BESS") Energy Storage Agreement
9 ("ESA") .
10 Q. Please provide additional information
11 regarding the Kuna BESS ESA.
12 A. On April 26, 2023, Idaho Power and Kuna BESS
13 entered into an ESA, whereby a battery storage facility
14 located in Kuna, Idaho, will supply 150 megawatts ("MW") of
15 capacity on Idaho Power' s system for the period of 20 years
16 from a commercial operation date of June 1, 2025 . The ESA
17 acts as a type of lease through which Kuna BESS will
18 develop, design, construct, own, and operate the battery
19 storage system and, in accordance with the terms of the
20 agreement, Idaho Power will supply the charging energy for
21 the system and has the exclusive right to dispatch and use
22 the charging and discharging energy in exchange for a
23 monthly payment .
24 On November 27, 2023, in Order No . 36011, the
25 Commission granted the Company' s Application for a
BRADY, DI 12
Idaho Power Company

1 Certificate of Public Convenience and Necessity to acquire
2 101 MW of new dispatchable energy storage to meet
3 identified capacity deficiencies, also approving the ESA
4 with Kuna BESS (subject to an update identified by Staff) ,
5 and acknowledging the lease accounting necessary to
6 facilitate the transaction and that the resulting expenses
7 associated with the ESA are prudently incurred for
8 ratemaking purposes .'
9 Q. How does the Company arrive at a "normalized"
10 look at base NPSE for ratemaking purposes?
11 A. In order to "normalize" base NPSE, the Company
12 uses AURORA to model various water conditions using current
13 loads and current resources . At this time, 37 water
14 conditions have been evaluated to develop an average or
15 normalized NPSE. This general methodology was adopted by
16 the Commission in 1981 and has been used in general rate
17 proceedings ever since.
18 Q. What is the currently approved base level
19 NPSE amount?
20 A. The currently approved 2023 Base Level NPSE
21 is $484, 907, 243 . It is comprised of the following
22 components :

3 Q. When was the currently approved base level
4 NPSE established and approved by the Commission?
5 A. The 2023 Base Level NPSE was established on
6 December 28, 2023, by Order No. 36042 issued in Case No .
7 IPC-E-23-11 .
8 Q. Since the establishment of the 2023 Base Level
9 NPSE, has the Company made any modifications to the AURORA
10 model in order to develop the 2025 Base Level NPSE?
11 A. Yes . In order to quantify the 2025 Base Level
12 NPSE, the Company utilized a new AURORA version and
13 database, which reflects updated inputs for the entire
14 Western Interconnection ("WECC") footprint. This database
15 was also used in the development of the Company' s 2023
BRADY, DI 14
Idaho Power Company

1 Integrated Resource Plan ("IRP") , which was acknowledged by
2 the Commission on June 18, 2024, in Order No. 36233 issued
3 in Case No . IPC-E-23-23 . The Company also updated the
4 database to include resource changes, current fuel prices,
5 and maintenance schedules .
6 Q. Have any additional resources been added to
7 the Company' s resource portfolio since the 2023 Base Level
8 NPSE was established?
9 A. Yes . The 2025 AURORA model includes the
10 addition of seven resources from the 2023 AURORA model . The
11 seven resources are listed below.
12 New Resources included in the 2025 AURORA Model
13 1 . Valmy Unit 1 Gas
14 2 . Franklin Solar PPA
15 3 . Pleasant Valley Solar PPA
16 4 . Franklin BESS
17 5 . Hemingway BESS Expansion
18 6 . Happy Valley BESS
19 7 . Kuna BESS
20 Q. Please describe the Valmy Unit 1 Gas resource,
21 including how it was modeled for the development of the
22 2025 Base Level NPSE .
23 A. The Company' s 2023 IRP Action Plan included
24 the conversion of Valmy Units 1 and 2 from coal to natural
25 gas by summer 2026 . Valmy Unit 1 is expected to be
26 converted prior to the end of 2025, and Valmy Unit 2 is
27 expected to be converted in 2026 . As discussed further in
28 Mr. Larkin' s testimony, I was directed to model Valmy Unit
BRADY, DI 15
Idaho Power Company

1 1 as a natural gas unit online for the entire 2025 test
2 year in order to more closely align 2025 Base Level NPSE
3 with the time period in which rates will take effect .
4 Q. How were Franklin Solar and Pleasant Valley
5 Solar modeled for the development of the 2025 Base Level
6 NPSE?
7 A. Franklin Solar, which came online June 2024,
8 is a 100-MW alternating current solar photovoltaic ("PV")
9 generation facility. The Company has a 25-year PPA with
10 Franklin Solar, LLC.
11 Pleasant Valley Solar, which came online March 2025,
12 is a 200-MW alternating current solar PV generation
13 facility. Pleasant Valley Solar is a PPA that was
14 negotiated in conjunction with Brisbie' s special contract,
15 which allows for Idaho Power to procure renewable resources
16 to support Brisbie' s operations with renewable energy.
17 While Pleasant Valley Solar is connected to the grid and
18 therefore does not serve Brisbie directly, Brisbie will pay
19 for the full cost of the PPA, as well as for Idaho Power
20 retail electric service required to serve their load. In
21 addition, Brisbie will receive a capacity credit for the
22 value that Pleasant Valley Solar provides to Idaho Power' s
23 system and will be credited for any PPA generation that
24 exceeds their load in a given hour. Because Brisbie does
25 not have load in the 2025 test year, all output from
BRADY, DI 16
Idaho Power Company

1 Pleasant Valley Solar is modeled as excess generation, with
2 the corresponding renewable capacity and excess generation
3 credits included in the 2025 Base Level NPSE.
4 The Company modeled both Franklin Solar and Pleasant
5 Valley Solar' s generation in AURORA by applying the
6 projects' expected hourly shape to the total annual test
7 year generation. In addition, both were modeled as
8 annualized online resources for the entire test year, in
9 line with the Company' s typical practice for resources
10 expected to come online during the test year.
11 Q. How were the four new BESS resources modeled
12 for the development of the 2025 Base Level NPSE?
13 A. Franklin BESS, co-located with Franklin Solar,
14 is a Build Transfer Agreement ("BTA") with Duke Energy
15 Renewables Solar, LLC, providing for a minimum capacity of
16 60 MW. The Hemingway BESS expansion resource represents the
17 addition of 36 MW of Idaho Power-owned battery storage at
18 the Hemingway substation. Happy Valley BESS represents the
19 addition of 80 MW of Idaho Power-owned battery storage at
20 the Happy Valley substation. Kuna BESS, as described
21 earlier in my testimony, represents a 20-year ESA for 150
22 MW of battery storage located in Kuna, Idaho.
23 The four new BESS resources were modeled so that the
24 scheduled generation of the batteries are shaped to the
25 Company' s demand, net of the "must-run" PURPA and PPA
BRADY, DI 17
Idaho Power Company

1 resources . In addition, all were modeled as annualized
2 online resources for the entire test year. Lastly, as by
3 name, Franklin BESS is modeled to be charged by Franklin
4 Solar while the other three BESS resources were modeled to
5 be charged from the entire grid.
6 Q. How was demand response modeled for the
7 development of the 2025 Base Level NPSE?
8 A. Demand response was modeled according to the
9 parameters of its three programs : A/C Cool Credit, Flex
10 Peak Program, and Irrigation Peak Rewards . Idaho Power
11 modeled the programs to provide a total of 320 MW of peak
12 capacity during June and July, with a reduced amount of
13 program potential available during August and September. As
14 stated on page 70 of the 2023 Integrated Resource Plan,
15 because the total potential from demand response is
16 dependent on anticipated load from program participants,
17 the reduced amount of potential available during August and
18 September is a result of irrigation load reducing over the
19 demand response program season.
20 Q. Have you prepared an exhibit that presents the
21 normalization of variable power supply expenses consistent
22 with the changes you have described in your testimony?
23 A. Yes . Exhibit No. 24 shows the results
24 containing the 37-year average variable power supply
25 generation sources and expenses .
BRADY, DI 18
Idaho Power Company

1 Q. Please summarize the sources and disposition
2 of energy shown on Exhibit No. 24 .
3 A. Hydro generation supplies 8 . 1 million
4 megawatt-hours ("MWh") , approximately 41 percent (8 . 1
5 million MWh / 19 . 7 million MWh = 41 percent) of the
6 generation mix. Thermal generation supplies 4 . 7 million
7 MWh (Bridger Coal 1 . 1, Valmy Coal 0 . 1, Bridger Gas 0 . 8,
8 Valmy Gas 0 . 3, Langley Gulch 1 . 8, Danskin 0 . 3, Bennett
9 Mountain 0 .2) , approximately 24 percent (4 . 7 million MWh /
10 19 . 7 million MWh = 24 percent) of the generation mix.5
11 Short-term market purchases supply 2 . 4 million MWh,
12 approximately 12 percent of the generation mix. PPA
13 generation supplies 1 . 7 million MWh, approximately 8
14 percent of the generation mix. PURPA generation reflects
15 normalized and annualized generation levels and accounts
16 for 2 . 9 million MWh, approximately 15 percent of the
17 generation mix. Total purchases amount to 7 . 0 million MWh
18 (2 . 4 million MWh + 1 . 7 million MWh + 2 . 9 million MWh = 7 . 0
19 million MWh) or approximately 36 percent of the generation
20 mix. Of the 19 . 7 million MWh generated by the system, 17 . 6
21 million MWh are utilized for system loads while 2 . 1 million
22 MWh are sold as surplus sales .
23 Q. Please summarize the expenses associated with
24 each resource as shown on Exhibit No. 24 .

5 transportation at Bridger and Valmy are $22 . 5 million.
6 Natural gas fuel expenses of $77 . 9 million are comprised of
7 Langley Gulch at $45 . 3 million, Danskin at $10 . 4 million,
8 and Bennett Mountain at $7 . 3 million. The fixed costs
9 related to pipeline capacity and transportation at these
10 plants are $15 . 0 million. Non-PURPA purchased power
11 expenses amount to $161 . 4 million and surplus sales revenue
12 (including transmission loss revenue and marginal cost-
13 priced energy sales revenue) is $101 . 1 million.
14 Q. How have natural gas prices changed between
15 the time of quantification of the 2023 Base Level NPSE and
16 the 2025 Base Level NPSE?
17 A. For the 2023 Base Level NPSE, natural gas
18 prices were assumed to be $3 . 36 per million British thermal
19 units ("MMBtu") for Henry Hub, $4 . 28 per MMBtu for natural
20 gas delivered to Bridger, and $4 . 70 per MMBtu for natural
21 gas delivered to Langley, Bennett Mountain, and Danskin.
22 For the 2025 Base Level NPSE, prices are forecasted to be
23 $4 . 42 per MMBtu for Henry Hub, $4 . 05 per MMBtu for natural
24 gas delivered to Bridger, and $3 . 55 per MMBtu for natural
25 gas delivered to Langley, Bennett Mountain, and Danskin.

Idaho Power Company

1 The 2025 forecast price for natural gas delivered to Valmy
2 Unit 1 is $4 . 03 per MMBtu.
3 Q. In general, how has base level NPSE and
4 generation changed from 2023 to 2025?
5 A. Due to the increase in steam generation
6 capacity from the addition of North Valmy Unit 1, as well
7 as an increase in fixed costs related to pipeline capacity
8 and transportation, expenses related to steam generation
9 have increased 76 percent from 2023 . Conversely, due to the
10 decrease in regional natural gas prices from 2023, expenses
11 related to natural gas generation have decreased 31 percent
12 compared to 2023 .
13 Next, non-PURPA purchased power expense has
14 increased 62 percent since 2023 . This is the result of the
15 addition of Franklin Solar and Pleasant Valley Solar, as
16 well as the increase in AURORA dispatched market purchase
17 volumes . PURPA expense has increased 6 percent since 2023,
18 which is largely attributed to updated PURPA contract
19 values .
20 Lastly, surplus sales revenue has increased 192
21 percent from 2023, which is largely attributed to the
22 increase in resources and decrease in regional natural gas
23 prices, which together created more opportunities to make
24 economic off-system sales in the 2025 test year. In
25 addition, revenue associated with marginal cost-priced
BRADY, DI 21
Idaho Power Company

1 energy sales is included in the total surplus sales revenue
2 for the 2025 test year.
3 Q. How are transmission losses on market
4 purchases (FERC Account 555) accounted for within the
5 Company' s calculation of 2025 Base Level NPSE?
6 A. Within the AURORA model, transmission losses
7 are incorporated into the market price paid by the
8 purchasing entity. In other words, the purchase price on
9 all short-term market purchases is grossed up to account
10 for transmission losses . As a result, the non-PURPA
11 purchased power expenses of $161 . 4 million included in FERC
12 Account 555 include both purchased power and transmission
13 losses on purchased power.
14 Q. Does the Company propose to update the base
15 level NPSE accounts that are not calculated by AURORA, or
16 partially calculated by AURORA, as part of this request?
17 A. Yes . The Company' s proposal reflects 2025
18 test year level amounts for the below FERC Accounts .
447 . 050 Transmission Loss Revenue
565 Third-Party Transmission Expense
536 . 003 Water for Power
555 Demand Response
577 . 4 Energy Storage Rents
19 Q. Did Idaho Power use the same methodology from
20 the 2023 Rate Case to determine the 2025 Base Level amount
21 for FERC Account 447 . 050, Transmission Loss Revenue?
BRADY, DI 22
Idaho Power Company

1 A. Yes . The 2025 test year amount for FERC
2 Account 447 . 050, Transmission Loss Revenue, was calculated
3 by multiplying Idaho Power' s average hourly marginal price,
4 as calculated by AURORA, by 36 MW, which is the estimated
5 average MW generated in each hour to serve third-party
6 transmission losses, according to the Company' s most recent
7 loss study.
8 Q. How did the Company determine the 2025 Base
9 Level amount for FERC Account 565, Third-Party Transmission
10 Expense?
11 A. The 2025 test year amount for FERC Account
12 565, Third-Party Transmission Expense, was calculated by
13 multiplying the Company' s 3-year average historical ratio
14 of market purchase volumes to actual third-party
15 transmission expenses by the AURORA calculated market
16 purchase volumes .
17 Q. How did the Company determine the 2025 Base
18 Level amounts for FERC Account 536 . 003, Water for Power and
19 FERC Account 555, Demand Response?
20 A. FERC Account 536 . 003, Water for Power, is
21 forecast at 0 for the 2025 test year. Idaho Power did not
22 have water lease expense amounts in 2024 and does not
23 anticipate any for the 2025 test year.
24 FERC Account 555, Demand Response, was quantified
25 for the 2025 test year based on expected Idaho-
BRADY, DI 23
Idaho Power Company

1 jurisdictionalized costs associated with projected
2 participation in the three programs .
3 Q. How did the Company determine the 2025 Base
4 Level amount for FERC Account 577 . 4, Energy Storage Rents?
5 A. The monthly expenses included in FERC Account
6 577 . 4, Energy Storage Rents, was quantified by multiplying
7 the per-month fixed contractual price, as stated in the
8 ESA, by the 150 MW of expected effective capacity.
9 Q. Does the Company propose to update the base-
10 level third-party wheeling revenues used in the calculation
11 of the annual wheeling revenue deferral, which is updated
12 annually with the PCA filing?
13 A. Yes . However, because third-party wheeling
14 revenues are not considered a part of NPSE, the proposed
15 2025 test year base-level wheeling revenues are quantified
16 in Mr. Larkin' s testimony.
17 Q. Have you quantified the 2025 Base Level NPSE
18 amounts?
19 A. Yes . The 2025 Base Level NPSE amounts as
20 proposed by the Company for Commission-approval are as
21 follows :

Total $534, 594, 853
3 Q. How do these 2025 Base Level NPSE amounts
4 compare with the 2023 Base Level NPSE amounts?
5 A. The 2025 Base Level NPSE total is
6 $534, 594, 853, an increase of $49, 687, 610 from the 2023 Base
7 Level NPSE of $484, 907, 243 .
8 Q. Is Idaho Power proposing to update Schedule
9 55, Power Cost Adjustment, with this filing?
10 A. Yes . As discussed in Mr. Larkin' s testimony,
11 the update to Base Level NPSE will result in a reduction in
12 the variance between base and forecast NPSE embedded in
13 current PCA rates . Therefore, Idaho Power has calculated an
14 updated PCA rate that incorporates the proposed 2025 Base
15 Level NPSE . If approved as filed, the Company' s 2025 Base
BRADY, DI 25
Idaho Power Company

1 Level NPSE would result in a reduction in PCA revenue
2 collection of $46, 781, 308, as discussed in Mr. Larkin' s
3 testimony. The calculations made to determine the updated
4 PCA forecast rate, as well as the decrease in PCA revenue
5 collection as a result of the 2025 Base Level NPSE update,
6 are provided in my workpapers .
7 Q. Have you prepared a revised Schedule 55 that
8 includes the updated PCA rate?
9 A. Yes . Attachments 1 and 2 to Idaho Power' s
10 Application filed concurrently herewith include a revised
11 Schedule 55 and includes the proposed PCA rates in clean
12 and legislative formats .
13 Q. Does this conclude your direct testimony in
14 this case?
15 A. Yes, it does .
