NEWS RELEASE: Commission approves eastern Idaho electric utility's application for federal
credit adjustment to customer bills.
BOISE (Sept. 24, 2025)—The Idaho Public Utilities Commission has approved an application
from Rocky Mountain Power to pass on a federal billing credit to residential and small farm
customers. The credit takes effect Oct. 1, 2025 and lasts until Sept. 30, 2028.
The annual power bill of a typical residential customer will decrease by approximately $51.87,
and the credit per kilowatt hour will increase from $0.007376 to $0.012545 per kilowatt hour.
The annual overall credit authorized for Idaho customers of Rocky Mountain Power has
increased from $7.93 million annually to $13.1 million annually.
The credit is the result of an agreement between the utility and the Bonneville Power
Administration. The agreement passes through to customers the benefits of the federal Columbia
River hydropower system. The amount of the credit is determined by formulas using a number of
factors, including a utility's average system cost for producing power.
