Oregon PUC approves rate increase for Avista customers, effective October 31

EASTERN OREGON – (Release from the Oregon Public Utility Commission) The Oregon Public Utility Commission (PUC) recently approved an overall increase in rates for Avista customers that goes into effect October 31, 2025.

The change is the result of several annual adjustments, including a decrease in natural gas prices combined with other filings focused on energy efficiency, customer programs, among others.

Customer Impact
The combined result of these annual filings means the monthly bill of a typical residential customer using an average of 46 therms per month will increase by $1.75 or 2.56%, bringing the average monthly bill to about $70.18. The amount rates will increase for each customer varies depending on customer type (residential, commercial, or industrial) and energy usage.

Reasons for the Adjustment

Each year the PUC reviews the actual cost of natural gas and approves adjustments to rates accordingly through a process called the Purchased Gas Adjustment (PGA). The PGA allows utilities to pass through the cost of purchasing natural gas to customers without a markup on the price. This year, natural gas prices were moderate, and Avista collected more than needed from customers last year. As a result, the PGA led to a decrease in natural gas costs in customers’ bills.

Despite the lower gas prices, other approved updates, such as funding for energy efficiency programs and customer support services, resulted in a net increase in rates. Altogether, these changes will raise Avista’s total revenue, or the amount collected from customers, by $4.1 million.

“Our goal is to ensure Avista’s rates reflect the true cost of providing service and are fair and reasonable for customers,” said PUC Chair Letha Tawney. “We carefully review all filings to ensure customers see accurate rates that reflect both market changes and essential utility costs.”
