Cascade Natural Gas Corporation proposes a 2.71 percent (or $5.9 million) increase in natural gas rates

KENNEWICK, WASHINGTON – Feb. 02, 2018 – On August 31, 2017, Cascade Natural Gas Corporation (Cascade) filed a general rate request with the Washington Utilities and Transportation Commission (WUTC) to increase gas base rates. If approved, the filed request would increase annual natural gas base revenues by $5.9 million (2.71 percent). However, the federal tax bill, the Tax Cuts and Jobs Act, will likely result in a decrease to a portion of this request. This request, as filed, includes a rate of return of 7.60 percent and 9.90 percent return on shareholder equity.

The WUTC will review Cascade’s request. It has up to 11 months to review the filing. If approved, changes will go into effect no later than August 1, 2018.

Capital investment in Cascade’s natural gas distribution system, as well as increased cost to operate and maintain that system, are the main drivers in Cascade’s request with the WUTC to increase prices.

 Bill Impact: The proposed rate will increase residential rates by 4.41%. The average residential customers using 54 therms per month will pay $2.09 more per month and the average industrial customer using 10,241 therms per month will pay $50.75 more per month.

Below is a chart showing what the typical customer in each customer class pays per month and what that customer would pay if the Company’s rate case proposal is approved.
