Federal Tax Savings Reduce Rates for Electric Customers

June 28, 2018

CHEYENNE, Wyo. — Changes in federal tax law from December 2017 will reduce rates for customers of Rocky Mountain Power by a 3.3 percent overall average. The Wyoming Public Service Commission approved rates on an interim basis effective July 1, 2018 with a final order to come later.

The effect on a typical Wyoming residential customer bill is a reduction of $3.15 per month, based on usage of 720 kilowatt-hours per month.

The reduction will appear on customer bills as a separate line item, “Tax and Jobs Act Adjustment.” The company proposes to pass back $22.5 million in benefits to Wyoming customers annually through Dec. 31, 2020.

In addition, Rocky Mountain Power included an additional reduction of $3.6 million to offset the 2018 adjustment for net power costs and renewable energy revenue that was submitted to the commission in April.

“Our customers already enjoy some of the lowest power costs in the country, and we are pleased to be able to reduce those rates even more,” said Cindy A. Crane, CEO and president, Rocky Mountain Power. “We have been able to reduce bills for our customers several times in recent years, reflecting our commitment to control the costs we can control and provide increased value to our customers.”
