Our 20-Year Plan

Idaho Power publishes an Integrated Resource Plan (IRP) every two years. 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 reviewed by regulators 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 660,000 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

In addition to participating in IRPAC meetings, customers are invited to submit questions using the form on this page or email our IRP team.

Information about how to join the next IRPAC meeting via Webex will be posted here when it is available.

Educational Resources

Idaho Power has assembled this list of educational resources to enhance public understanding of the IRP process and reduce the time spent in IRPAC meetings reviewing background material.
