Georgia Power has begun construction of a 200-megawatt (MW) battery energy storage system (BESS) in Twiggs County, southeast of Macon, Georgia. The project, approved by the Georgia Public Service Commission on September 4, 2025, is adjacent to the existing Twiggs County Solar facility and is projected for completion in 2027.

The Twiggs BESS is designed to dispatch stored energy over a four-hour period, enhancing grid reliability and resilience while maximizing the value of intermittent renewable resources like solar. These systems store excess energy during low-demand periods for use during peak demand, improving efficiency and flexibility for the electricity grid.

Rick Anderson, senior vice president and senior production officer at Georgia Power, said the project will help the company serve existing customers while supporting Georgia's growth and renewable energy integration.

Construction is being carried out by Crowder Industrial Construction, LLC. In addition to Twiggs County, Georgia Power is building four other BESS facilities totaling 765 MW across Bibb, Cherokee, Floyd, and Lowndes counties, with expected completion in 2026.

Looking ahead, Georgia Power is pursuing approval for 10 new BESS facilities totaling 3,022.5 MW, alongside two new solar-plus-storage projects totaling 350 MW. The company is also seeking bids for 500 MW of additional energy storage systems with at least a two-hour discharge duration, with projects expected online by 2031.

These initiatives are part of Georgia Power's strategy to maintain a diverse, balanced energy portfolio while increasing renewable integration and grid flexibility across the state.
