BPA credit adjustment to Idaho customer power bills

BOISE, Idaho — Rocky Mountain Power was authorized by the Idaho Public Utilities Commission to pass on a federal billing credit to certain residential or farm customers in Idaho. The annual credit authorized for Idaho customers of Rocky Mountain Power has decreased from $10.3 million annually to $7.93 million annually. The change to the authorized credit increases the annual power bill of a typical residential customer by about $27.34 and takes effect beginning October 1, 2023, through September 30, 2025.

The Bonneville Power Administration Residential Exchange Program is designed to share the benefits of the Federal Columbia River Power System with residential and small farm customers of investor-owned electric utilities in Idaho and other Northwest states. The program began in 1980 through the Bonneville Power Administration, a federal power marketing agency under the U.S. Department of Energy. The BPA benefits have significantly lowered the bills of qualifying residential and small farm customers during the course of the program. The exchange benefits are passed directly to customers by Rocky Mountain Power and have no effect on the utility’s revenues.

The following is a summary of the percentage impacts by customer class:

  • Residential Schedule 1 – 2.6% increase
  • Residential Schedule 36 – 3.1% increase
  • General Service Schedule 6A – 3.7% increase
  • Irrigation Service Schedule 10 – 1.2% increase
  • General Service Schedule 23A – 3.1% increase
  • Public Street Lighting 7A – 1.2% increase

We understand the impact that price increases have on our customers and will work to mitigate the impact of the BPA credit change as much as possible. Customers can visit RockyMountainPower.net/Wattsmart for tips and information on how to save energy and money.

The commission must approve the proposed changes before they can take effect. A copy of the company’s application is available for public review on the commission’s website, www.puc.idaho.gov, under Case No. PAC-E-23-19. Customers may also subscribe to the commission’s RSS feed to receive periodic updates via email. The request is required to be available at the company’s offices in Rexburg, Preston, Shelley, and Montpelier, although the company urges customers to visit our website at rockymountainpower.net/rates.
