Idaho Power has filed a proposed settlement agreement with the Idaho Public Utilities Commission (IPUC) in the company’s 2025 general rate case. If approved by the commission, the settlement will result in an overall rate increase of $110 million, or 7.48%, for Idaho customers that will go into effect on January 1, 2026. This rate case impacts Idaho customers only.
What is a general rate case?
A general rate case is a proceeding used by the IPUC to review the costs of operating and maintaining the utility system and how those costs are allocated among customers.
Why did Idaho Power file a general rate case?
Unprecedented levels of capital investment needed to meet growing customer demands and maintain our infrastructure drove the need for this rate case. Idaho Power expects to invest more than $1 billion in our system in 2025. Establishing new general rates will help us recover the costs of safely and reliably providing electric service to our growing service area, including building new energy production and storage resources, grid investments, wildfire resilience, labor, and other investments needed to run a healthy and effective utility.
What are the proposed customer impacts?
If the settlement is approved, an average Idaho residential customer using 900 kilowatt-hours per month will see a monthly bill increase of about $12.13. Proposed impacts for all Idaho customers are shown in the table. Actual percentages will depend on a customer’s classification and the rate they pay. The settlement does not include any changes to the monthly service fee.

What is Idaho Power doing to keep costs down?
Idaho Power has a strong track record of keeping its costs — and prices — low. The company has saved money and improved reliability by performing certain maintenance tasks with its own crews and refurbishing outdated equipment in-house. Idaho Power also strives to help customers save energy and money through energy efficiency. In 2024, energy efficiency programs saved 143,537 megawatt-hours — enough to power 12,600 average-sized homes for a year. While Idaho Power remains committed to affordability, unprecedented levels of capital investment necessary to meet growing customer demands and maintain our infrastructure is driving the need for this request.
What resources does Idaho Power have to help customers struggling to pay their energy bill?
Project Share is a year-round energy assistance program administered by the Salvation Army and funded by customer donations and Idaho Power shareholder funds. Idaho Power also offers energy assistance programs and convenient features like Budget Pay that can help customers manage their energy bills.
What happens next?
A customer hearing is scheduled for Nov. 20 in Boise (11331 W. Chinden, Building 8, Suite 201-A), from 4:30 to 7:30 p.m., with a virtual option. More information is available on the IPUC website.
The IPUC will issue a final order on this case, likely near the end of December.
