Overall change in electric prices would be effective July 1, 2025
SPOKANE, Wash., March 31, 2025 (GLOBE NEWSWIRE) — Avista (NYSE: AVA) has made a filing with the Washington Utilities and Transportation Commission (Commission or WUTC) that, if approved, will result in an increase of $15.3 million, or 2.1 percent, in electric rates in Washington, effective July 1, 2025.
The request reflects a rate adjustment to recover from customers certain deferred power supply costs tracked in the Company’s Energy Recovery Mechanism (ERM). The ERM is a mechanism that tracks the difference between actual power supply-related costs experienced by Avista to the authorized level approved by the Commission.
Under the mechanics of the Commission-approved ERM, if Avista has a cumulative deferral balance of $30 million or higher, Avista is required to either surcharge, or rebate, that deferred balance to customers. In 2024, the primary driver of increased power supply costs experienced by the Company was reduced hydroelectric generation due to lower-than-expected precipitation and snowpack. Increased costs in 2024, along with the accumulation of prior years’ ERM balances that have not yet been passed through to customers, has resulted in a cumulative ERM balance of $34.3 million.
Avista is presently recovering approximately $19.0 million in ERM-related expenses in customer rates, which will end July 1, 2025. Therefore, the combined effect of the current ERM balance expiring, offset by the proposed ERM recovery proposed in this filing, is a net ERM-expense recovery of $15.3 million, or 2.1%. The Company’s filing seeks to recover this balance, which includes the associated interest, from customers effective July 1, 2025 over a 12-month period.
