SUBJECT: IN THE MATTER OF IDAHO POWER COMPANY'S APPLICATION
FOR A CERTIFICATE OF PUBLIC CONVENIENCE AND NECESSITY
FOR TWO BATTERY STORAGE FACILITIES; CASE NO. IPC-E-24-45.
On December 27, 2024, Idaho Power Company ("Company") applied for a Certificate of
Public Convenience and Necessity ("CPCN") for two dispatchable battery facilities providing a
total of 100 megawatts ("MW") of operating capacity. The Idaho Public Utilities Commission
("Commission") subsequently issued notice of the application and set an intervention deadline.
Order No. 36454. The Industrial Customers of Idaho Power, Idaho Irrigation Pumpers
Association, Inc., and Micron Technology, Inc. intervened. Order Nos. 36485 & 36492. The
Commission then issued a Notice of Modified Procedure, establishing a May 7, 2025, public
comment deadline and a May 28, 2025, Company reply deadline.
On May 2, 2025, Staff of the Idaho Public Utilities Commission ("Staff') moved to 1)
vacate the existing May 7, 2025, public comment deadline and May 28, 2025, company reply
deadline established in Order No. 36569; and 2) reset them to June 11, 2025, and July 2, 2025,
respectively.
Staff filed its motion to extend the comment deadlines the day after the Company
informed Staff that recent increases in U.S. government tariffs on goods imported from China
will substantially affect the cost of the battery facilities involved in this case. Staff requests that
the Commission vacate the current May 7, 2025, public comment deadline and reset it for June
11, 2025, believing this extension will provide Staff with sufficient time for the development of
informed comments addressing the anticipated cost increase for the battery facilities. To provide
DECISION MEMORANDUM I

the Company with the same 21-day response period established by the current comment
deadlines, Staff requests that the Commission vacate the current May 28, 2025, Company reply
deadline and reset it for July 2, 2025.
