Re: Tariff Case No. PAC-TAE-26-01
Modify Electric Service Schedule No. 21 —Low Income Weatherization Services
PacifiCorp,d/b/a.Rocky Mountain Power(the"Company"),hereby submits Tariff Case No.PAC-
TAE-26-01 for electronic filing with the Idaho Public Utilities Commission requesting authority
to modify Electric Service Schedule No. 21 — Low Income Weatherization Services ("LIW
Program")with an effective date of July 1, 2026.
Attached hereto as Exhibit A are clean and legislative copies of the modified tariff sheets. Below
is a summary of the sheets modified and a description of the changes to them.
Fifth Revision of Sheet No. 21.3 Schedule 21 Low Income Weatherization Services
Fourth Revision of Sheet No. 21.5 Schedule 21 Low Income Weatherization Services
Second Revision of Sheet No. 21.6 Schedule 21 Low Income Weatherization Services
Changes to Financial Assistance
The current administrative fee structure was established in 2006, and has remained unchanged to
the present day. Given the increases in administrative workload, project complexity with
technology advancements, and other factors such as inflation since 2006, the Company proposes
to increase the minimum administrative fee from $5 0 per job to $100 per job, and increase the
maximum administrative payments for each tier by$150,as reflected in Exhibit A.These proposed
increases will more accurately reflect current administrative efforts and ensure fair compensation
for the time and resources required to manage each project efficiently. Additionally, the annual
program cycle has been shifted to July 1st through June 30th to align with state agencies' program
cycles.
Changes to Energy Conservation Measures
Currently, agencies that serve households under the LIW Program voluntarily provide energy
education to customers. Agency auditors, crews, and inspectors each spend time voluntarily
educating customers on the planned measures, reviewing basic energy-savings practices,
distributing energy-saving pamphlets and kits,and demonstrating the operation of completed work
while emphasizing the importance of routine maintenance, such as furnace filter replacement. The
Company proposes to make energy education a required service under the LIW Program to ensure

the information is made available to all participants. The Company will provide a $100 incentive
to agencies for each educated household served under the LIW Program.
Cost Effectiveness
The proposed changes to the administrative fee structure and energy conservation measures are
expected to have an inconsequential impact on the LIW Program's cost effectiveness.
