ORDER NO. 36238
On May 31, 2024, Idaho Power Company ("Company") filed an application
("Application") with the Idaho Public Utilities Commission ("Commission") requesting an order
approving a revision to the Company's schedules of rates for electric service in the state of Idaho.
The Company requests an increase in annual Idaho jurisdictional revenue of $99,293,220. The
Company represents that if approved, this request would result in an overall increase to adjusted
base revenue of 7.31 percent.
The Company asserts that it intends to invest nearly one billion dollars in its system in
2024, and an average of $796 million over the next five years to meet the growing customer
demand and to maintain a safe, reliable electric system. The Company represents that with these
planned investments, increased labor costs, and other inflationary pressures, the revenue from
current rates is no longer sufficient to maintain a reasonable rate of return,nor adequate cash flow,
to support the Company's financial stability without the relief requested.
The Company acknowledges that the Commission has recently issued an order on its last
general rate case ("GRC"); however, the Company believes a rate case limited to only certain
maters will provide timely cost recovery, while minimizing the rate increases customers might
otherwise experience with a full GRC.
The Company proposed an effective date of July 1, 2024, with the understanding that the
Commission would likely suspend the proposed effective date. The Company's Application is
structured around an anticipated effective date of January 1, 2025.
