Southern Company subsidiary PowerSecure is collaborating with Powder River Energy Corporation and NRTC to develop a utility-scale battery storage and solar generation project in Moorcroft, Wyoming. The project will address grid-level peak demand challenges driven by industrial growth and rural load expansion.

The integrated solution includes a 5 MW battery energy storage system with 21.6 MWh capacity alongside 1.25 MWdc of ground-mount solar generation. It is expected to reduce PRECorp’s annual wholesale power costs by up to $1 million and provide backup capacity during outages and extreme conditions.

Construction is slated to take approximately two years with system commissioning targeted in 2027. This deployment enhances Southern Company’s distributed energy infrastructure credentials and positions the company for further rural utility partnerships.
