Portland, Ore. – NW Natural customers in Washington have new rates that include the combined effects of a rate case and the annual Purchased Gas Adjustment (PGA), both recently approved by the Washington Utilities and Transportation Commission (WUTC).

In total, the impacts of both adjustments mean Washington customers can expect to see new rates on monthly bills starting November 1:

  • Rates for residential customers in Washington will be about $9.15 more a month for customers using an average of 57 therms per month.
  • Rates for small-commercial customers in Washington will be about $36.74 more a month for customers using an average of 236 therms per month.

Why the rate change?

The Purchased Gas Adjustment reflects a pass-through of natural gas commodity costs to customers. The changes are driven by multiple factors, including economy-wide supply and demand impacts during the COVID-19 pandemic, coupled with higher prices experienced during last winter’s heating season.

In addition to the commodity cost, the approval of the Washington rate case recovers operating costs and investments in greater system reliability and resiliency.

Natural gas continues to be an affordable and efficient source of energy. NW Natural customers are still paying nearly 30% less today for their bills than they did 15 years ago, due to lower commodity costs coupled with efficient operations and energy-efficiency measures.
