Rocky Mountain Power requests general rate increase of 26.8%
IDAHO FALLS, Idaho (KIFI) - Rocky Mountain Power is requesting a rate increase for Idaho customers.
The request comes as the Idaho Public Utilities Commission approved their annual energy cost adjustment rate increase starting June 1, 2024.
The energy cost adjustment rate will increase the average residential customer using 783 kilowatt-hours of electricity by about $7.39.
Rocky Mountain Power is now filing a request with the Idaho Public Utilities Commission for a general rate increase of 26.8% or $92.4 million over the next two years.
In a news release, the company said, "To ease the effects of these increased costs on customer bills, the company proposed a rate mitigation plan to phase in the requested increase through two rate changes. Specifically, $66.7 million or 19.4 percent of the overall increase would become effective on January 1, 2025, and $25.7 million or 6.3 percent from 2025 rates would become effective on January 1, 2026..
The average residential customer would see an increase of 17.9%, or about $19.90 on January 1, 2025, and an increase of 5.3%, or about $6.94 on January 1, 2026.
They say even with the proposed increase, Idaho customers will pay among the lowest rates in the nation for their electric service.
