SPOKANE, Wash., March 28, 2025 (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 Climate Solutions/Green Energy Institute at Lewis & Clark Law School, 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 issues in the proceeding.

If approved, this settlement would result in a base revenue increase of $4.2 million, as compared to Avista’s original request of $7.8 million. The agreed-upon revenue requirement is predicated on a proposed rate of return of 7.219% with a common equity ratio of 50% and a 9.5% return on equity. As a part of the settlement, the parties agreed to accelerate the use of certain customer tax credits to partially mitigate the billed impact to customers, over a three-year period. As a result, the overall increase customers would experience is 2.0%.

"Our goal is to provide safe, reliable energy for our customers, and timely recovery of our costs allows us to maintain the infrastructure crucial to delivering on this goal. We are pleased with this settlement agreement and believe that it provides a fair outcome for our customers and shareholders alike," said Heather Rosentrater, Avista President and CEO.

Residential Customer Bills
If the settlement is approved, a residential natural gas customer using an average of 48 therms per month, would see a $1.36 per month increase, or 2.0 percent, from a $69.55 bill for a revised monthly bill of $70.91 effective Sept. 1, 2025.
