Black Hills Energy customers in Cheyenne could see higher utility bills next year.

The company in a news release Thursday said Cheyenne Light, Fuel and Power has filed a rate review application with the Wyoming Public Service Commission requesting $15.4 million in new annual revenue.

The last rate increase occurred in 2013 with rates effective in October 2014.

Since that time, the company says it has invested approximately $250 million in safety, reliability, and system integrity for its 1,330 miles of electric distribution and 59 miles of electric transmission lines, which serve approximately 44,000 electric customers in Cheyenne.

"To serve the current and expanding energy needs of our customers, it's pivotal for us to maintain reliable service and build a resilient system," said Mark Stege, Vice President of Wyoming Operations.

"In the coming months, we’ll work with the Wyoming Public Service Commission and stakeholders to create a clear-cut 'win' for reliable, cost-efficient energy and ongoing economic growth for our state," Stege added.

If approved as filed, the average residential customer using about 600 kWh of electricity each month could see a rate increase of about 15%, with small commercial customers seeing an increase of about 11%.
