Georgia Power has celebrated the commercial operation of its first “grid-connected” Battery Energy Storage System (BESS) at the Mossy Branch facility.
This system, with a capacity of 65 megawatts (MW) for four-hour deployment, is designed to improve energy reliability and resilience in Georgia’s power grid.
The Mossy Branch BESS can store excess renewable energy (e.g., solar power) during low-demand periods and release it during high-demand times, enhancing the grid’s efficiency and stability.
This technology is expected to improve grid resilience, particularly during extreme weather conditions.
Wartsila, an energy technology company, partnered with Georgia Power to deliver the Mossy Branch project, providing an advanced energy management platform and compact storage system for secure, efficient operations.
Alongside Mossy Branch, Georgia Power is developing additional storage projects, including a 265 MW facility in Cherokee County by 2026.
Plans are underway to add 1,000 MW of BESS through competitive bidding and company-owned projects, with new installations planned near Robins Air Force Base, Moody Air Force Base, and other strategic locations.
Georgia Power’s investment in battery energy storage aligns with its long-term energy strategy, promoting renewable energy use, grid reliability, and environmental sustainability across the state.
