Federal Tax Savings Reduce Rates for Electric Customers

May 01, 2018

SALT LAKE CITY — Changes in federal tax law from December 2017 will reduce rates for customers of Rocky Mountain Power by a 4.7 percent overall average, effective May 1, 2018.

The effect on a typical residential customer bill is a reduction of $4.17 per month, based on usage of 698 kilowatt-hours per month.

The reduction will appear on customer bills as a separate line item, “Tax Act Adjustment.” Following an order by the Public Service Commission of Utah, $61 million in benefits will be passed through to Utah customers by Dec. 31, 2018.

“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.”

Rocky Mountain Power continues to review the more complex details of the tax law change and agreed with Utah utility regulators to provide the total impact of the new law on June 15, which will likely result in additional benefits to customers.
