Our 20-Year Plan

Idaho Power’s Integrated Resource Plan (IRP) examines the demand for energy over the next 20 years and the best ways to meet that demand for our customers. The plan is updated every two years and includes a series of public meetings that help guide our planning process. The 2019 IRP was submitted to the Idaho Public Utilities Commission and the Public Utility Commission of Oregon in June 2019.

In July 2019, Idaho Power informed the commissions that the company needed to perform supplemental analysis related to the modeling approach used to develop the IRP. The amended IRP was submitted Jan. 31, 2020.

In May 2020, the company identified additional model inputs that needed to be reviewed and potentially adjusted. We used this opportunity to conduct a thorough review of our entire IRP process, from the data sources to modeling inputs to outputs. The subsequent adjustments are reflected in the final version of the IRP that was filed Oct. 2, 2020. The Second Amended 2019 IRP, along with its appendices, is linked below.

The IRP describes the company’s projected need for additional electricity and the resources necessary to meet that need while balancing reliability, environmental responsibility, efficiency, risk and cost.

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 consists of members of the environmental community, major industrial customers, irrigation representatives, state legislators, 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 570,000 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.
