New rates for 2025/2026
Each year, NW Natural files a Purchased Gas Adjustment (PGA) to reflect changes in the expected cost of natural gas for the upcoming winter heating season and account for the differences between the estimated and actual cost of natural gas from the previous year. NW Natural does not mark-up the price of gas; the PGA is a passthrough of costs for the wholesale price and delivery of natural gas.
Despite periods of extraordinary market conditions, the average NW Natural customer bill, over a year, is about the same as it was 20 years ago.[1]The average bill for a NW Natural residential customer in our Oregon/Washington service territory in 2006 was $85.79; that average bill now is $83.70. This is based on the average amount of gas used per customer.
