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 is paying less for natural gas bills than 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.

Notice of request for rate increase in Washington: On August 29, 2025, NW Natural filed a general rate change request with the Washington Utilities and Transportation Commission (WUTC). It’s been five years since NW Natural filed for a rate case to cover system investments. Since then, costs have escalated from inflation, higher material prices and operations and maintenance expenses.

To continue delivering safe, reliable service, NW Natural is proposing a three-year adjustment under the state’s new multi-year rate statute, which aims to help customers plan for the impacts associated with increasing costs.

If the initial request is approved as filed, the average residential customer who has been connected to our system on or before July 25, 2021 would see an increase of about 22% for the first year (August 2026 – July 2027), followed by about a 5% increase for each of the next two years. The average small-commercial customer would see an increase of about 23% for the first year (August 2026 – July 2027), followed by about a 6% increase for each of the next two years.

For residential customers with newer connections, those increases would be about 20% for the first year, followed by increases of about 5% for each of the next two years. Newer connected small-commercial customers would see an increase of about 21% for the first year (August 2026 – July 2027), followed by about a 5% increase for each of the next two years.

The request will not impact customer bills for this upcoming winter season (2025-2026). If approved, new rates would take effect starting August 1, 2026.

Frequently asked questions

Why are my rates changing now?

Does NW Natural mark-up the price of natural gas?

What is NW Natural doing to manage costs for customers?

NW Natural has taken several steps to maximize affordability, such as locking in gas purchases at lower rates, smart investments in energy storage, and energy efficiency measures.

NW Natural’s purchasing process locks in future prices to help manage costs for customers.
Smart investments in gas storage in the 1980s continue to reap benefits for customers today. Storage helps moderate gas costs during the core heating season
NW Natural was one of the first gas utilities in the nation to implement a rate structure based on decoupling, beginning in 2002. Decoupling is designed to break the link between revenues and the quantity of gas used by customers, removing any financial incentive a utility might have to discourage customers from conserving energy. Today more than 75% of our gas utility revenues are decoupled.

It seems like the cost of everything is increasing right now and I’m concerned about paying my bill. What programs do you have?

Other payment assistance options are available, including:

How is my gas bill calculated?

Our rates are regulated and approved by the Public Utility Commission of Oregon (OPUC) and the Washington Utilities and Transportation Commission (WUTC). The current charges on your bill are based on up to five components:

Monthly service or minimum charge
Gas usage cost
Smart Energy carbon offset program charge
Local taxes
Public purpose charge

Overall, about 90% of your bill goes toward the cost of gas, delivery and the services provided to you as a customer, with the remaining 10% going toward regulated rate of return on NW Natural’s investment in the gas system. More information is available about how to understand your natural gas bill.
