ORDER NO. 36584
On April 15, 2025, Idaho Power Company ("Company"), filed an application with the
Idaho Public Utilities Commission ("Commission") requesting an order approving an update to
Schedule 55 based on the quantification of the 2025-2026 Power Cost Adjustment ("PCA") to
become effective June 1, 2025, for the period of June 1, 2025, through May 31, 2026.
BACKGROUND
The PCA mechanism permits the Company to increase or decrease its PCA rates to reflect
the Company's annual "power supply costs." Due to its diverse generation portfolio, the
Company's actual cost of providing electricity varies from year to year depending on changes in
such things as the river streamflow, the amount of purchased power, fuel costs, the market price
of power, and other factors. The annual PCA surcharge or credit is combined with the Company's
"base rates"to produce a customer's overall energy rate.
The PCA quantifies and tracks annual differences between actual Net Power Supply
Expenses("NPSE")and the normalized or"base level"of NPSE recovered in the Company's base
rates, resulting in a credit or surcharge that is updated annually on, June 1. The PCA mechanism
uses a 12-month test period from April through March ("PCA Year") and includes a forecast
component and a Balancing Adjustment. The forecast component represents the difference
between the Company's NPSE forecast from the March Operating Plan and base level NPSE
recovered in the Company's base rates. The Balancing Adjustment includes a backward-looking
tracking of differences between the prior PCA Year's forecast and actual NPSE incurred by the
Company and also tracks the collection of the prior year's Balancing Adjustment.
NOTICE OF APPLICATION
NOTICE OF MODIFIED PROCEDURE
ORDER NO. 36584 1

Except for Public Utility Regulatory Policies Act of 1978 ("PURPA") expenses and
demand response incentive payments, the PCA allows the Company to pass through to customers
95 percent of the annual differences in actual NPSE as compared with base level NPSE, whether
positive or negative. With respect to PURPA expenses and demand response incentive payments
and actual annual expenses deviate from base level NPSE, the Company is allowed to pass 100
percent of the difference for recovery or credit through the PCA. The PCA is also the rate
mechanism used by the Company to provide customer benefits resulting from the revenue sharing
mechanism, approved by the Commission in Order No. 34071.
NOTICE OF APPLICATION
YOU ARE HEREBY NOTIFIED that the Company represents that the proposed 2025-
2026 PCA rates would result in total PCA collection of$21 million, which represents a decrease
in total billed revenue of$94.8 million for the upcoming year, or 5.89 percent. Application at 13.
YOU ARE FURTHER NOTIFIED that the Company represents that Table 1 shows the
separation of the$94.8 million decrease into each component included in the Company's proposed
rates:

Id.
YOU ARE FURTHER NOTIFIED that the Company represents that the decrease in this
year's PCA is driven by a decrease in the Balancing Adjustment,which is largely attributed to the
completed recovery of the 2023 PCA balancing adjustment and partially offset by an increase in
the forecast component. Id. The Company states that additional factors include the Sales-Based
Adjustment, an increase in Renewable Energy Credit sales, a credit related to wheeling revenues,
and a credit for liquidated damages. Id.
