Georgia Power has begun construction on a 200-megawatt battery energy storage system (BESS) in Twiggs County, southeast of Macon, Georgia. The new project, located next to the existing Twiggs County Solar facility, was selected as part of the company’s 2023 Integrated Resource Plan (IRP) Update and received approval from the Georgia Public Service Commission (PSC) on September 4, 2025.
The BESS is designed to dispatch stored energy quickly over a four-hour period. Battery storage systems help improve the reliability and resilience of the electric grid and increase the value of renewable resources such as solar by storing excess energy produced during low-demand periods for use when demand is higher. These facilities are intended to address power needs identified in the IRP update in a cost-effective way.
Rick Anderson, senior vice president and senior production officer for Georgia Power, stated: “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. With the construction of the 200 MW 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, LLC is building the Twiggs BESS facility. Completion is expected in 2027.
Georgia Power also has four other BESS projects under construction across Bibb, Cherokee, Floyd, and Lowndes counties with a combined capacity of 765 MW. These facilities are projected to be completed in 2026.
Additionally, Georgia Power is seeking regulatory approval for ten new BESS sites totaling more than 3 gigawatts of capacity as part of its All-Source Request for Proposals (RFP). Two new solar systems paired with storage are also planned. Site selection prioritized locations at existing company plant sites or near substations.
The company has issued another RFP for an additional 500 MW of energy storage systems with at least two hours’ discharge duration. This procurement process is managed by Ascend Analytics on behalf of Georgia Power. The goal is for qualified projects to be online by no later than 2031.
