Black Hills Corp. (NYSE: BKH) filed a rate review application with the Colorado Public Utilities Commission requesting $26.7 million in new annual revenue to recover costs for capital infrastructure and operations serving over 102,000 customers in Southern Colorado.

The utility company seeks to recover approximately $184 million in investments made since its last rate review, including 2024 additions aimed at improving reliability, strengthening the electric grid, and extending the life of generation infrastructure.

"As we deliver on our responsibility to provide safe and reliable energy to improve the lives and livelihoods of our customers and communities, this request supports our ability to make the required investments to maintain our electric system," said Linn Evans, president and CEO of Black Hills Corp.

The rate request is based on a capital structure of 51.02% equity and 48.98% debt with a return on equity of 10.5%. Black Hills Corp. plans to implement new rates in the first quarter of 2027.

Based in Rapid City, South Dakota, Black Hills Corp. serves 1.37 million natural gas and electric utility customers across eight states: Arkansas, Colorado, Iowa, Kansas, Montana, Nebraska, South Dakota and Wyoming.
