WAITES, DI 1
Idaho Power Company

1 Q. Please describe your work experience with
2 Idaho Power.
3 A. I began my employment with Idaho Power in
4 December 2004 in the Accounts Payable Department. In 2005,
5 I accepted a Regulatory Accountant position in the Finance
6 Department where one of my tasks was to assist in
7 responding to regulatory data requests pertaining to
8 financial issues . In 2006, I accepted a Regulatory Analyst
9 position in the Regulatory Affairs Department where my
10 duties included providing support for the Company' s various
11 regulatory activities, including tariff administration,
12 regulatory ratemaking, and compliance filings, and the
13 development of various pricing strategies and policies . In
14 January 2014, I was promoted to Regulatory Consultant where
15 my responsibilities expanded to include the development of
16 complex cost-related studies and the analysis of strategic
17 regulatory issues . I was promoted to my current position,
18 Regulatory Projects Coordinator, in March 2025, providing
19 project management and coordination for regulatory cases
20 and issues, leading and coordinating regulatory activities .
21 Q. What is the Company' s request in this case?
22 A. Idaho Power is requesting the Idaho Public
23 Utilities Commission ("Commission") issue an order (1)
24 granting a Certificate of Public Convenience and Necessity
25 ("CPCN") for the South Hills Power Plant, a cost-effective
WAITES, DI 2
Idaho Power Company

1 natural gas-fueled facility providing up to 222 megawatts
2 ("MW") of nameplate generation ("South Hills") to meet an
3 identified capacity deficit in 2029, (2) granting a CPCN
4 for the Peregrine Power Plant, a cost-effective natural
5 gas-fueled facility providing 430 MW of nameplate
6 generation ("Peregrine") to meet an identified capacity
7 deficit in 2030, and (3) confirmation of the Company' s
8 application of accrual of Allowance for Funds Used During
9 Construction ("AFUDC") for both the South Hills and the
10 Peregrine plants to coincide with initial procurement
11 activities for the natural gas-fueled facilities . The South
12 Hills and Peregrine plants are necessary for Idaho Power to
13 continue to provide safe, reliable electric service in 2029
14 and beyond.
15 Q. What is the purpose of your testimony in this
16 proceeding?
17 A. The purpose of my testimony is to describe
18 AFUDC and the commencement of its accrual as soon as funds
19 are expended and committed to a construction project. For
20 generation resources, this has typically occurred
21 subsequent to the request for a CPCN. However, because of
22 the long lead times associated with materials, Idaho Power
23 has incurred expenditures associated with the Peregrine
24 plant prior to filing the request for a CPCN, and
25 anticipates expenditures associated with South Hills within
WAITES, DI 3
Idaho Power Company

1 the next two months, and therefore is requesting the
2 Commission approve the accrual of AFUDC for both projects
3 when expenditures are first incurred.
4 I . ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION
5 Q. Please describe AFUDC.
6 A. A generally accepted accounting principle,
7 AFUDC represents the opportunity cost of funds used during
8 construction of utility projects . Idaho Power records the
9 accumulation of all costs associated with the construction
10 of an asset, including the cost of financing the
11 construction expenditures, or AFUDC, in Federal Energy
12 Regulatory Commission ("FERC") Account 107 - Construction
13 Work in Progress ("CWIP") . When the plant is completed and
14 placed in service, the total cost of the plant, including
15 AFUDC, is moved to FERC Account 101 - Electric Plant-in-
16 Service, placing the asset in rate base. In effect, during
17 construction, the Company is allowed to earn a return on
18 CWIP by accruing AFUDC, but typically the cash recovery
19 does not occur until the associated plant is placed in
20 service and authorized for recovery in a rate proceeding,
21 which strains the Company' s credit quality.
22 Q. When does the accrual of AFUDC begin on a
23 capital project?
24 A. Guidance from FERC suggests AFUDC shall begin
25 when (1) capital expenditures for the project have been
WAITES, DI 4
Idaho Power Company

1 incurred, and (2) activities that are necessary to get the
2 construction project ready for its intended use are in
3 progress . Activities include all actions required to
4 prepare the construction project for its intended use,
5 including activities prior to physical construction, such
6 as the development of plans or the process of obtaining
7 permits from governmental authorities .' Accordingly, Idaho
8 Power commences accrual of AFUDC as soon as funds are
9 expended and committed to a construction project.
10 Q. How do these activities differ from
11 preliminary survey and investigation ("PS&I") activities
12 for which AFUDC does not accrue?
13 A. In accordance with Order No. 29904,2 costs
14 associated with investigation into the viability of
15 potential resources identified as part of the Integrated
16 Resource Plan are recorded to PS&I accounts . For example,
17 for benchmark bids prepared for submittal into a Request
18 for Proposals ("RFP") for new generation resources by the
19 Company' s Internal Bid Team, any consulting fees incurred
20 to aid in the development of an RFP bid submittal would be
21 charged to PS&I as the project' s viability as a least-cost,
22 least-risk resource has not yet been determined.

Modifying the Accounting Procedures for Preliminary Survey and Investigation
Charges, IPC-E-05-21.
WAITES, DI 5
Idaho Power Company

1 Q. When does Idaho Power deem a project viable or
2 infeasible?
3 A. In the past, once selected on the final
4 shortlist having been identified as a least-cost, least
5 risk resource, and subsequently acknowledged by the Public
6 Utility Commission of Oregon ("OPUC") in accordance with
7 the competitive bidding rules, Idaho Power moves the
8 charges to FERC Account 107 - CWIP as the viability of the
9 project has been confirmed, and AFUDC commences . However,
10 as explained in more detail in the Direct Testimony of Mr.
11 Adam Richins, based on industry demand for long-lead
12 materials, and to ensure commercial operation dates are
13 met, the Company has been incurring capital expenditures
14 associated with resource procurements much earlier than
15 Idaho Power previously experienced.
16 II . PROPOSED ACCOUNTING TREATMENT
17 Q. When does the Company commence accrual of
18 AFUDC?
19 A. In the past, payment for procurement of
20 materials has typically not occurred until after Idaho
21 Power has filed a request for a CPCN with the Commission,
22 at which time the Company commences AFUDC accrual .
23 However, in order to secure a position in the queue to
24 purchase the turbine for Peregrine, Idaho Power was
25 required to make a down payment of approximately $_
WAITES, DI 6
Idaho Power Company

1 - in June 2025 . In addition, a payment for the
2 reciprocating internal combustion engines ("reciprocating
3 engines") for South Hills will be made in the next two
4 months . The reciprocating engines and turbine reservation
5 payments are necessary to ensure both plants would be
6 operational in time to meet the identified capacity needs .
7 Because of current supply chain demands, our entire
8 industry, including Idaho Power, has been experiencing
9 longer lead times for the core components for generation
10 facilities (e .g. , turbines and transformers) and therefore
11 is seeking confirmation of the appropriateness to commence
12 the accrual of AFUDC once the necessary relatively large
13 expenditures for the resources are incurred to ensure
14 timely delivery.
15 Q. Does the Company believe accrual of AFUDC once
16 payments are made for materials is consistent with FERC' s
17 guidance?
18 A. Yes . A down payment for materials is evidence
19 that capital expenditures are being incurred and the
20 procurement is necessary to begin construction of the
21 project, which aligns with FERC' s guidance on the
22 commencement of AFUDC accrual . However, because Idaho
23 Power will incur costs associated with resource
24 procurements prior to receiving a CPCN, the Company is
25 requesting the Commission acknowledge it is appropriate to
WAITES, DI 7
Idaho Power Company

1 begin the accrual of AFUDC once the South Hills and
2 Peregrine had been deemed viable and expenditures
3 associated with the resource procurements have been
4 incurred. This treatment would recognize the required
5 upfront investments made by the Company in pursuit of
6 cost-effective, necessary resources to safely and reliably
7 serve customers .
8 Q. Is this treatment similar to the treatment
9 sought in Case No. IPC-E-25-29, Idaho Power' s request for
10 a CPCN for the Bennett Mountain Gas Expansion Project?
11 A. Yes . In addition to the request for a CPCN,
12 the Company requested confirmation of the application of
13 the accrual of AFUDC for the Bennett Gas Expansion Project
14 to coincide with initial procurement activities . The
15 Commission approved Idaho Power' s request to commence
16 accrual of AFUDC to coincide with initial procurement
17 activities for the Bennett Gas Expansion Project with
18 Order No. 36958 .
19 Q. Is Idaho Power requesting the Commission deem
20 the accrued AFUDC amounts prudent at this time?
21 A. No. The Company is not seeking a prudence
22 determination of any project costs incurred at this time .
23 Rather, once the South Hills and Peregrine plants have
24 been completed and placed in-service, Idaho Power will
25 file a request with the Commission for a review and
WAITES, DI 8
Idaho Power Company

1 approval of all prudently incurred project costs,
2 including any accrued AFUDC amounts .
3 III . CONCLUSION
4 Q. Please summarize your testimony.
5 A. Idaho Power records the accumulation of all
6 costs associated with the construction of an asset,
7 including AFUDC, in CWIP. When the plant is completed, the
8 total cost of the plant, including AFUDC, is moved to
9 Electric Plant-in-Service, placing the asset in rate base .
10 The Company commences accrual of AFUDC as soon as funds are
11 expended and committed to a construction project, which,
12 for generation resources, has typically occurred subsequent
13 to the request for a CPCN. Because of long lead times,
14 Idaho Power has incurred expenditures for South Hills and
15 Peregrine prior to receiving a CPCN for either plant. The
16 Company is requesting the Commission confirm Idaho Power' s
17 treatment of the accrual of AFUDC for both projects is
18 appropriate when expenditures are first incurred, which
19 occurred prior to a request for a CPCN.
20 Q. Does this complete your testimony?
21 A. Yes, it does .
