New Rates Take Effect November 1, 2018

NW Natural customers will be paying lower rates starting Nov. 1. This is the fourth straight year that the cost of natural gas has dropped, and customers are still paying less than they did 15 years ago.

Customers can get more information by calling us at 503-226-4211 and asking for the Rates and Regulatory Department.

Rate changes vary based on different use patterns by customer class, as well as differences in rate structures between Oregon and Washington.


In Oregon, new customer rates incorporate the conclusion of the general rate case and the results of the annual Purchased Gas Adjustment (PGA). Together these adjustments result in a 2.1% or $1.10 savings for an average residential customer using 53 therms per month. Commercial customers will save 2.4% or $4.92 per month based on an average usage of 237 therms.

The new rates include the Public Utility Commission of Oregon’s (OPUC) approval of a $23.4 million base rate increase. The increase recovers costs of company operations and investments in greater system reliability and resiliency.

The new rates also include the recently approved PGA reduction of 6.2% in residential rates and 5.8% in small commercial rates. Filed each year, the PGA takes into account a lower cost of natural gas, which is primarily the result of an abundant supply projected for the year ahead, and other year-to-year adjustments and costs approved by regulators.


Washington customers will also be paying less on their gas bills due to the PGA, which was recently approved by the Washington Utilities and Transportation Commission. Rates for residential customers in Washington will be about 7.2% less. A typical residential customer using an average of 57 therms per month will see a monthly savings of about $3.81. Rates for small commercial customers in Washington will be about 7.7% lower, or $16 less for those using an average of 244 therms per month.

Note: On December 31, 2018, NW Natural filed for a 12.6% base rate increase with Washington Utilities and Transportation Commission (WUTC). More information can be found here.
