Idaho Power has filed a request with the state's public utilities commission to raise rates, which could increase monthly bills by around 3.15% or $3.64 for a typical residential customer using 900 kilowatt-hours per month. The utility says the hike is largely driven by higher expected power costs in the coming year, including lower forecasted hydropower production.

Why it matters

Rate increases can significantly impact household budgets, especially for lower-income customers. As a major electricity provider in Idaho, any changes to Idaho Power's rates will affect a large portion of the state's residents and businesses.

The details

Idaho Power's proposed rate hike consists of a Power Cost Adjustment (PCA) requesting an overall increase of $51.56 million, or 3.02%, as well as a Fixed Cost Adjustment (FCA) seeking an additional $5.12 million increase that would apply only to residential and small commercial customers. Combined, the two filings would result in a total revenue increase of about $56.7 million, or 3.31% statewide.

  • Idaho Power filed the PCA with the Idaho Public Utilities Commission.
  • If approved, the new rates would take effect on June 1, 2026.
