Avista Makes Annual Price Adjustment Requests in Washington
SPOKANE, Wash., Aug. 31, 2026 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA) – Avista’s Washington natural gas customers would see lower monthly bills this winter under annual rate adjustment requests the company filed today with the Washington Utilities and Transportation Commission (WUTC). These filings seek to true-up the level of costs in customer rates with the actual level incurred by the Company.
If approved, the requests would decrease natural gas rates by approximately 11.5%, while electric rates would remain nearly unchanged. The largest natural gas adjustment is related to Washington’s Climate Commitment Act and would reduce rates by approximately 11%. Additionally, the filing includes a reduction related to the cost of supply and transportation of natural gas. The electric adjustments are small and largely offset one another. Together, they would reduce electric rates by approximately 0.01%, resulting in little to no noticeable change in customer bills.
“We know many families and businesses are paying close attention to every expense right now,” said Heather Rosentrater, president and CEO of Avista. “These annual adjustments are separate from our pending general rate case and reflect specific costs that are reviewed every year in Washington. For natural gas customers, this year’s filing would result in lower bills heading into the winter heating season.”
Effect on customer bills
Natural gas customers—If approved by the WUTC, most residential natural gas customers in Washington using an average of 61 therms per month would see their monthly bills decrease by approximately $7.38, from $96.18 to $88.80 - a decrease of approximately 7.7%.
The large decreases for non-Schedule 101 customers is due to differing impacts of the Purchase Gas Adjustment (PGA) on the various rate schedules, especially for transportation service schedule 146 customers who procure their own wholesale natural gas and interstate transportation service and are not subject to the PGA. In addition, because the Climate Commitment Act (CCA) charges make up a smaller portion of a residential customers bills, the decrease from the CCA results in a larger impact for non-residential customers.
Electric customers—If approved by the WUTC, residential electric customers in Washington using an average of 925 kilowatt-hours per month would see their monthly bills decrease by approximately $0.05, from $125.69 to $125.64 - a decrease of approximately 0.04%.
Actual bill impacts vary based on rate schedule and energy usage.
