Avista Makes Annual Price Adjustment Filings in Idaho

AVA
  • Avista filed annual rate adjustment requests with the Idaho Public Utilities Commission to align customer rates with actual incurred costs, with no projected impact on company earnings.
  • Three natural gas filings seek updates effective November 1, 2026, including a 3.0% decrease in Purchased Gas Cost Adjustment (PGA), a 2.8% increase in Fixed Cost Adjustment (FCA), & a 1.6% decrease in Energy Efficiency Adjustment.
  • Three electric filings seek updates effective October 1, 2026, including a 4.2% increase in Power Cost Adjustment (PCA), a 1.2% increase in Fixed Cost Adjustment (FCA), & a 0.1% decrease in the Bonneville Power Administration Residential Exchange Program.
  • Residential natural gas customers in Idaho using an average of 66 therms per month would see monthly bills decrease by $0.90 (approx. 1.5%) from $59.28 to $58.38 if natural gas filings are approved.
  • Residential electric customers in Idaho using an average of 939 kilowatt hours per month would see monthly bills increase by $7.76 (approx. 6.5%) from $119.52 to $127.28 if electric filings are approved.
  • The proposed natural gas rate changes result in an overall revenue decrease of 1.8%, driven primarily by lower wholesale gas prices & the suspension of natural gas energy efficiency programs effective November 1, 2026.
  • The proposed electric rate changes result in an overall revenue increase of 5.3%, driven by the expiration of a 2025 rate credit, higher power costs, & increased electricity usage.
  • The Electric FCA mechanism adjusts revenues based on customer counts to account for usage variations due to weather or efficiency programs, excluding Extra Large General & Street Lighting Service Schedules.
  • Avista plans to set natural gas Energy Efficiency Collection rates to $0.00 per therm effective November 1, 2026, to pause operations until cost-effectiveness standards are met again.
  • The Bonneville Power Administration Residential Exchange filing seeks to slightly increase credits to qualifying customers to return an under-rebated balance from previous fluctuations.
  • Filings are subject to public review at the Idaho Public Utilities Commission, with comments accepted via the Commission's website or by mail.
