Cascade Natural Gas files to decrease rates in Washington

(KENNEWICK, WASH.)- Cascade Natural Gas on September 15, 2025, filed several annual cost adjustments, including its annual purchased gas cost adjustment, with the Washington Utilities and Transportation Commission (WUTC). If the WUTC approves all proposals the combined effect is an overall decrease in annual revenues of 16.17%.

The impact to an average residential customer using 53 therms per month will be a net decrease of $14.23 per month, or 13.69%, according to a news release from Cascade Natural Gas.

The filings submitted to the WUTC for consideration also include the cost recovery for participatory intervenor costs incurred from December 1,2022 through October 31, 2025, a decoupling mechanism adjustment, a conservation adjustment, an unprotected excess deferred income tax adjustment, and recovery of uncollected costs from the Cascade Arrearage Relief Energy Savings (CARES) program cost. The changes are proposed to become effective November 1, 2025.

The purchased gas cost adjustment application is filed each year to ensure the costs Cascade Natural Gas incurs on behalf of its customers are reflected in its sales prices. The cost of natural gas is a straight passthrough to customers; Cascade does not earn a profit on the cost of natural gas.
