RE: CASE NO.PAC-E-18-08
IN THE MATTER OF THE APPLICATION OF ROCKY MOUNTAIN POWER FOR
AUTHORIZATION TO CHANGE DERECIATION RATES APPLICABLE TO
ELECTRIC PROPERTY -Notification
Attention: Commission Secretary
In Order No. 34754 issued on August 18,2020 in this case,the Idaho Public Utilities Commission
approved a stipulation that included the following language in paragraph 20, "The Stipulating
Parties agree that in the next depreciation study, which the Company plans to file in 2025 with
new depreciation rates effective no earlier than January 1, 2026, the Company agrees to present
an analysis supporting the proposed lives and net salvage values for all Company-owned wind
resources."
Rocky Mountain Power (the "Company") is providing notice that the depreciation study planned
for 2025 has been delayed and the Company now plans on filing a new depreciation study in 2026.
The Company needs additional time for a third-parry decommissioning study to be completed later
this year in order to be incorporated into new proposed depreciation rates.
Informal inquiries may be directed to Mark Alder, Idaho Regulatory Manager at(801) 220-2313.
Sincerely,
Ja a Saba
Director, Regulation
