Avista Seeks Rate Adjustments in Idaho Ahead of Fall Season
Avista has filed annual price adjustment requests with the Idaho Public Utilities Commission (IPUC). The filings would update natural gas rates on November 1, 2026, and electric rates on October 1, 2026.
The proposed changes aim to balance actual costs incurred by Avista with customer rates. For natural gas, the Purchased Gas Cost Adjustment (PGA) filing seeks a decrease of $2.5 million or 3.0%, while the Fixed Cost Adjustment (FCA) would increase by approximately $2.4 million or 2.8%.
Residential natural gas customers using an average of 66 therms per month could see their monthly bills decrease from $59.28 to $58.38, a decline of $0.90 per month or 1.5%. For electric rates, the Power Cost Adjustment (PCA) filing proposes an increase of approximately $14.6 million or 4.2%, while the FCA would rise by around $4.0 million or 1.2%.
Residential electric customers using an average of 939 kilowatt hours per month could see their monthly bills increase from $119.52 to $127.28, a hike of $7.76 per month or approximately 6.5%. The proposed rate changes would take effect on October 1 and November 1, 2026, respectively.
The rate adjustments are primarily driven by variations in customer usage due to weather and savings from participating in efficiency programs. Avista's applications are subject to public review and a Commission decision.
