AUTHORITY TO DECREASE ELECTRIC ) ORDER NO. 36820
SERVICE SCHEDULE 191 - CUSTOMER )
EFFICIENCY SERVICES RATE )
On June 25, 2025,Rocky Mountain Power, a division of PacifiCorp("Company"), applied
("Application") for authorization to lower the rate for Electric Service Schedule No. 191—
Customer Efficiency Services Rate Adjustment ("Schedule 191"). The Company requests
processing of this matter via Modified Procedure.
On August 8,2025,the Commission issued a Notice of Application and Notice of Modified
Procedure, establishing public comment and Company reply deadlines. Order No. 36712. Staff
filed the only comments.
BACKGROUND
Established in 2006, Schedule 191 is intended to allow the Company to recover
Commission-approved Demand-Side Management("DSM")costs.The Company annually reports
financial data to track collections, DSM expenses, account balances, and program cost-
effectiveness.
THE APPLICATION
According to the Company, Schedule 191 has an over-collected balance of$4,658,434 as
of May 31,2025. The Company expects the over-collection to continue if rates remain unchanged,
projecting a $7.4 million over-collection by the end of 2028. To address this, the Company
proposes reducing the Schedule 191 rate from 2.50% to 1.92% effective November 1, 2025. This
would reduce the over-collected balance to about $10,325 by 2028. Under the proposed rate, a
typical residential customer using 836 kWh per month would save approximately $8.40 per year.
STAFF COMMENTS
After reviewing the Application, Staff supported reducing the Schedule 191 rate to 1.92%
to better align revenues with projected DSM expenditures through 2028 based on forecasted
participation and costs.
ORDER NO. 36820 1

During informal meetings with Staff, the Company explained that the over-collection
occurred because its budgets were based on meeting Integrated Resource Plan targets, but actual
program participation and spending were lower than forecasted. The Company stated that it
expects to spend more than it collects after decreasing the Schedule 191 rate, reducing the over-
funded Schedule 191 balance. Forecasted DSM program costs are $7.3 million in 2025, $8.6
million in 2026, $9.3 million in 2027, and$9.8 million in 2028.
The Company believed that a smaller rate decrease now would be less disruptive for
customers than more frequent changes. Staff agreed and recommended approving the 1.92% rate
through at least January 2028 to align revenues with expenditures and maintain rate stability.
The Company included its press release and customer notice related to this rate change
with the Application. Staff reviewed both and confirmed they comply with Rule 125 of the
Commission's Rules of Procedure. IDAPA 31.01.01.125. The notice was distributed with July
2025 bills, giving customers until October 1, 2025, to comment. No customer comments were
received by the deadline.
COMMISSION FINDINGS AND DECISION
The Commission has jurisdiction over this matter under Idaho Code §§ 61-501, -502,
and-503.The Commission is empowered to investigate rates,charges,rules,regulations,practices,
and contracts of public utilities and to determine whether they are just, reasonable, preferential,
discriminatory, or in violation of any provision of law, and to fix the same by order. Idaho Code
§§ 61-502 and-503.
The Commission has reviewed the record, including the Application and the comments
of Staff. Based on our review, we find it reasonable to approve the Company's Application and
proposed tariff. The Company has established the need to adjust the Schedule 191 rate to 1.92%.
This will allow the Company to reduce the existing deferral balance while mitigating the risk of
inflicting rate shock on customers.
ORDER
IT IS HEREBY ORDERED that the Company's Application to decrease the Schedule
191-Customer Efficiency Services Rate to 1.92% is approved.
IT IS FURTHER ORDERED that the Company's proposed Schedule 191 tariff is approved
as filed.
