The Washington State Utilities and Transportation Commission has signed off on a modest rate increase for Cascade Natural Gas customers.
Starting in September, the average residential gas customer using 54 therms a month will pay $1.39 more, for an average monthly bill of $55.86. It is an overall rate increase of 1.6 percent.
The percentage was reached in a settlement agreement between the commission’s staff and Kennewick-based Cascade Natural Gas, but required approval by the state commission.
The company initially asked to raise rates by 4.17 percent, or $10.5 million, but the agreement filed in May recommended the lower increase, which would total $4 million.
Never miss a local story.
Cascade’s last general rate increase was in 2007.
The commission received 29 public comments on the proposed rate increase, with 25 opposed and four undecided.
