Idaho Power has completed its 2025 Integrated Resource Plan (IRP) and filed it with regulators for review. The IRP examines the company’s projected need for additional electricity over the next 20 years and the resources that will best meet that need while balancing reliability, cost, environmental responsibility, efficiency and risk. The plan is updated every two years and includes a series of public meetings that help guide our planning process.
Idaho Power enlists the assistance of its customers in developing the IRP through an advisory panel — the Integrated Resource Plan Advisory Council (IRPAC).
The IRPAC includes major industrial customers, the environmental community, irrigation representatives, state and local elected officials, public utility commission representatives and other interested parties.
The IRPAC meets with Idaho Power regularly over a period of several months during the development of the company’s IRP. These meetings are public. The advisory council’s responsibilities include:
- Representing the interests of Idaho Power’s more than 650,000 customers
- Participating in open and active discussions of relevant issues, and
- Working with Idaho Power to develop ways to engage the public in the IRP process.
Public Input
IRPAC meetings for the 2025 IRP cycle have concluded. Idaho Power submitted the IRP to regulators for review on June 27. The public will be able to provide comments to the public utility commissions in Idaho and Oregon. Links to those dockets will be posted here when they are available. The final IRP and related appendices are available below.
Information about how to be involved in developing the 2027 IRP will also be posted here.
