PowerSecure, a subsidiary of Southern Company and a leading provider of resilient, innovative energy solutions, is collaborating with Powder River Energy Corporation (PRECorp) and the NRTC to advance a utility‑scale battery energy storage and solar generation project in Moorcroft, Wyo. 

This project is designed to help PRECorp address grid‑level peak demand challenges driven by industrial growth and rural load expansion, while reducing annual power costs for its members and strengthening system reliability through added backup capacity. The system is also expected to help PRECorp reduce annual wholesale power costs by up to $1 million, while delivering critical backup power capacity during outages and extreme conditions. 

The integrated solution will include a 5 MW battery energy storage system with a total energy capacity of 21.6 MWh and 1.25 MWdc of ground‑mount solar generation, providing greater operational flexibility and supporting improved peak demand management.
