Public Input Available After Avista Proposes 7.4% Average Rate Increase

The Oregon Public Utility Commission (PUC) is hosting a virtual public comment hearing on Wednesday, June 7, 2023, at 6 p.m. The event provides customers of Avista an opportunity to comment via Zoom on the impacts of the utility’s proposed increase to natural gas rates. Customers may also submit comments in writing or by phone through June 22, 2023, to be included in staff’s opening testimony of this case.

Avista filed a request to increase rates by 7.4 percent on average over all 106,000 Oregon customers. This would impact customer rates differently depending on usage and customer type – residential, business, or industrial customers. For a residential customer in a single-family home using an average 47 therms per month, a current monthly bill is about $77.01. With Avista’s proposed increase, the average residential customer bill would increase to about $83.21 per month. For the average residential customer, this represents an increase of $6.20 a month, or an 8.06 percent increase.

Avista identifies additional capital investments, including investments to maintain and expand its natural gas distribution facilities, and the effect of high inflation levels on the company’s operational costs, including interest rates, labor, and materials as the reasons for the proposed increase. 

Avista’s general rate change request is undergoing a nearly year-long review and will be fully investigated on behalf of natural gas customers by the PUC, the Oregon Citizens’ Utility Board, the Alliance of Western Energy Consumers, Sierra Club and Climate Solutions. This public comment hearing is part of that investigation, which will conclude in December when the Commissioners rule on the request. New rates, if approved, are expected to go into effect January 1, 2024. Any rate change approved as part of this general rate change filing would be in addition to the annual adjustment made to customer rates for the actual price of natural gas for the year. The purchased gas adjustment, which can be an increase or a decrease in customer rates, would go into effect November 1, 2023.
