Southern Power announced that the 150-megawatt (MW) South Cheyenne Solar Facility in Laramie County, Wyoming, is now operational. This project, Southern Power's 30th solar facility, is Southern Power's first solar facility in Wyoming, and it contributes to the company's growing fleet of clean energy resources from California to Maine. The electricity and associated renewable energy credits generated by the facility will be sold under a 20-year power purchase agreement with Cheyenne Light, Fuel and Power, a subsidiary of Black Hills Energy.

The energy will be used exclusively to provide renewable energy to a data center customer.
