Avista has filed its annual rate adjustment requests with the Idaho Public Utilities Commission, proposing changes that would lower residential natural gas bills by about 1.5 percent and raise residential electric bills by roughly 6.5 percent. The natural gas filings include a Purchased Gas Cost Adjustment decrease of approximately 2.5 million dollars, a Fixed Cost Adjustment increase of about 2.4 million dollars, and an Energy Efficiency Adjustment decrease of around 1.4 million dollars, resulting in a net overall natural gas rate reduction of 1.8 percent. The electric filings include a Power Cost Adjustment increase of approximately 14.6 million dollars, a Fixed Cost Adjustment increase of about 4.0 million dollars, and a Bonneville Power Administration Residential Exchange Program decrease of roughly 0.3 million dollars, leading to a net overall electric rate increase of 5.3 percent. If approved, the new rates would take effect November 1, 2026 for natural gas and October 1, 2026 for electric service. The filings are designed to true up costs with actual expenses and do not impact Avista's earnings.
