Avista reaches all-party, all-issues settlement in Oregon general rate case

SPOKANE, Wash., Aug. 03, 2023 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA), the Staff of the Public Utility Commission of Oregon (Commission), the Oregon Citizens’ Utility Board (“CUB”), Alliance of Western Energy Consumers (“AWEC”), and the joint intervenor Sierra Club/Climate Solutions, parties to the Company’s natural gas general rate case, have reached a settlement agreement that has been submitted to the Commission for its consideration, and which would resolve all remaining issues in the proceeding.

If approved, this settlement would result in a base revenue increase request of $7.16 million (or 4.7%), as compared to Avista’s original request of $11.0 million. The agreed-upon revenue requirement is predicated on a proposed rate of return of 7.235% with a common equity ratio of 50% and a 9.5% return on equity.

“This settlement agreement will provide new rates in Oregon that are fair and reasonable for our customers, the Company, and our shareholders,” said Dennis Vermillion, Avista president and CEO. “This outcome allows us to recover our costs in a timely manner and supports Avista’s efforts to invest in and maintain our infrastructure so we can continue to provide the reliable energy our customers expect.”

Residential Customer Bills
If the settlement is approved, a residential natural gas customer using an average of 47 therms per month, would see a $4.07 per month increase, or 5.3 percent, from a $77.01 bill for a revised monthly bill of $81.08 effective Jan. 1, 2024.
