Georgia Power has commenced construction of a 200MW battery energy storage system (BESS) in Twiggs County, southeast of Macon, Georgia.
The project, adjacent to the existing Twiggs County Solar facility, is designed to rapidly dispatch stored energy over a four-hour window. The BESS aims to bolster grid reliability and resilience while enhancing the value of intermittent renewables such as solar. By storing surplus energy generated during low-demand periods, the system can supply power during peak times – particularly on cold winter mornings when solar output is limited.
These installations form part of Georgia Power’s strategic response to support the state’s growing energy demands.
“At Georgia Power, our collaboration with the Georgia PSC and other stakeholders is key to making necessary investments for a reliable and resilient power grid,” said Rick Anderson, senior vice president and senior production officer for Georgia Power. “With the construction of the 200MW BESS in Twiggs County, we will be able to better serve our existing customers and support Georgia’s growth. As we expand our energy mix to include more renewable sources, these batteries will play an invaluable role in helping to ensure reliability and flexibility, particularly when renewable sources are not available.”
Crowder Industrial Construction is leading the build, with completion expected in 2027. Four additional BESS sites totalling 765MW – located in Bibb, Cherokee, Floyd and Lowndes counties – are also under construction, with commissioning anticipated in 2026.
