CASE NO. IPC-E-19-08
CASE NO. IPC-E-22-05
IDAHO POWER COMPANY’S
MOTION FOR EXTENSION OF
TIME TO COMPLY WITH ORDER
NOS. 34349 AND 35494
Idaho Power Company (“Idaho Power” or “Company”) respectfully moves the
Idaho Public Utilities Commission (“Commission”) to (1) acknowledge the Company will
file its North Valmy Power Plant (“Valmy”) Levelized Revenue Requirement Balancing
Account 2022 Annual Review (“2022 Annual Review”), as required by Order No. 34349,
as part of Idaho Power’s 2023 General Rate Case, and in doing so, (2) approve an
extension of time to meet the Valmy prudence determination filing requirements of Order
No. 35494.
MOTION FOR EXTENSION OF TIME - 2
1. Valmy is a coal-fired power plant that consists of two units and is located
near Winnemucca, Nevada. Unit 1 went into service in 1981 and Unit 2 followed in 1985.
Idaho Power owns 50 percent of Valmy. NV Energy is the co-owner of the plant with the
remaining 50 percent ownership and operates the Valmy facility. The Company exited
coal-fired operations of Unit 1 December 31, 2019, as accepted by the Commission in
Order No. 33983 as part of Idaho Power’s 2017 Integrated Resource Plan.
2. With Order No. 33771 in Case No. IPC-E-16-24, and updated by Order No.
34349 in Case No. IPC-E-19-08, the Commission approved a balancing account
mechanism designed to smooth revenue requirement impacts associated with the
shutdown of Valmy and allow for full recovery of Valmy-related costs near the plant’s end-
of-life. In addition, it more closely aligns the cost recovery period with the remaining
operating life of the plant, resulting in a better matching of cost recovery from customers
who benefit from the plant’s operations while mitigating the risk of future customers
bearing the costs of a plant that will no longer be providing service.
3. In Case No. IPC-E-19-08, Idaho Power requested the Commission (1)
approve the North Valmy Project Framework Agreement between NV Energy and Idaho
Power dated as of February 22, 2019, (2) find that all actual Valmy investments through
December 31, 2018, were prudently incurred, (3) allow investments forecasted through
December 31, 2025, at Valmy to be included in the levelized revenue requirement
mechanism, and (4) adjust customer rates to recover the associated incremental annual
levelized revenue requirement. As part of their approval of the Company’s request, the
Commission in Order No. 34349 also instructed Idaho Power to (1) “file an annual report
detailing the amounts recorded to the Valmy balancing account,” and (2) “to submit a filing
no later than February 28, 2022 to true-up the balancing account with forecast-to-actuals,
with rates to become effective June 1, 2022.”1
1 Order No. 34349 at 4.
MOTION FOR EXTENSION OF TIME - 3
4. Therefore, on February 28, 2022, in Case No. IPC-E-22-05, Idaho Power
filed a request with the Commission for an order (1) finding that all actual Valmy
investments made during the January 1, 2019, through December 31, 2021, time period
were prudently incurred, (2) validating that Idaho Power has accurately quantified the
Valmy balancing account true-up as a result of the inclusion of actual costs through
December 31, 2021, and updated forecasted investments through December 31, 2025,
and (3) confirming the request satisfies the annual reporting required by Commission
Order No. 34349. Although Order No. 34349 required the Company’s filing to include a
rate change effective June 1, 2022, Idaho Power did not propose to adjust customer rates
at that time.
5. In their review of Idaho Power’s request, Commission Staff found that the
Company accurately quantified the Valmy balancing account true-up. In their audit, Staff
analyzed two types of prudence, decisional prudence, which is based on need, and
operational prudence, which is based on whether or not the Company implemented the
investment in the least-cost manner. Commission Staff concluded that the investments
were needed to continue safe and reliable operation of the facility, or decisional prudence,
but indicated they could not “recommend that the investments were operationally prudent
due to lack of sufficient evidence documenting that the projects were done in a least-cost
way.”2 As such, Commission Staff recommended Idaho Power work with them to develop
the documentation necessary for Commission Staff’s audit and prudence review and
provide Commission Staff with the additional information via a compliance filing within six
months of the Commission’s order to determine prudence.3
6. In Reply Comments, the Company proposed a slightly different procedural
approach, under which the information to further support prudence of the investments

MOTION FOR EXTENSION OF TIME - 4
made during the January 1, 2019, through December 31, 2021, time period is submitted
as part of the 2022 Annual Review. The Company envisioned filing this report as a new
case that would include the 2022 Annual Review and the prudence determination for
these investments in the first quarter of 2023, resulting in administrative efficiency for both
the Commission and Staff. With Order No. 35494, the Commission indicated it was “fair
just and reasonable for the Company to file additional documentation to support a
prudence determination as part of the 2022 Annual Review” after working with
Commission Staff to expand the documentation process.4 Although not explicitly stated,
Idaho Power assumes the Commission agreed with Idaho Power’s proposed timing to file
the 2022 Annual Review in the first quarter of 2023.
7. Since issuance of Order No. 35494, the Company has been working with
Commission Staff to better understand the type of information they need to make a
recommendation regarding operational prudence. While significant progress has been
made, the parties have not completed memorializing and finalizing the information and
documentation necessary for Commission Staff’s prudence review and therefore is not
able to file the 2022 Annual Review along with the further support for prudence of the
investments made during the January 1, 2019, through December 31, 2021, time period
in the first quarter of 2023. However, as indicated in the Notice of Intent filed concurrently
with this Motion, the Company anticipates filing a General Rate Case on or after June 1,
2023. Idaho Power proposes to include as part of that proceeding both the 2022 Annual
Review, in compliance with Order No. 34349, as well as the information to support
prudence of Valmy investments made since January 1, 2019, in compliance with Order
No. 35494.
4 Order No. 34594 at 6.
MOTION FOR EXTENSION OF TIME - 5
8. Idaho Power appreciates Commission Staff’s continued coordination with
the Company to identify the additional documentation necessary to make a prudence
determination. The Company anticipates finalization of the support will occur in the near-
term and therefore the filing of the 2022 Annual Review and the prudence determination
would coincide with timing of the 2023 General Rate Case filing. For administrative
efficiency for both the Commission and Staff, Idaho Power proposes to include the 2022
Annual Review and prudence determination as part of the 2023 General Rate Case
proceeding. Therefore, the Company respectfully requests the Commission issue an
order (1) acknowledging Idaho Power will file its 2022 Annual Review as part of Idaho
Power’s 2023 General Rate Case, and in doing so, (2) approve an extension of time to
meet the Valmy prudence determination filing requirements of Order No. 35494.
DATED at Boise, Idaho, this 31st day of March 2023.
