Georgia Power has started construction on a 200-megawatt battery energy storage system (BESS) in Twiggs County, located southeast of Macon, Georgia. The project is situated next to the existing Twiggs County Solar facility and was chosen through a competitive process as part of the company’s 2023 Integrated Resource Plan (IRP) Update. The Georgia Public Service Commission approved the construction on September 4, 2025.
The new system is designed to store and dispatch energy quickly over a four-hour period. Battery storage projects like this one are intended to improve the reliability and resilience of the electric grid while supporting renewable generation sources such as solar power. These systems allow excess energy generated during periods of low demand to be stored for use during peak demand times when renewable sources may not be available.
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 responsible for building the Twiggs BESS project, which is expected to be completed by 2027.
In addition to this facility, four other BESS projects totaling 765 MW are under construction across Bibb, Cherokee, Floyd, and Lowndes counties. These facilities also received approval in the 2023 IRP Update and are expected to be finished by 2026.
Georgia Power is seeking further approval from state regulators for ten additional BESS sites with a combined capacity of over 3 gigawatts (3,022.5 MW), as well as two new solar installations paired with battery storage totaling 350 MW. Locations were selected based on deployment potential at company-owned sites or near substations.
The company is also accepting bids for another 500 MW of energy storage systems that can provide at least two hours of discharge duration. This request for proposals (RFP), managed by Ascend Analytics on behalf of Georgia Power, covers both standalone systems capable of charging from the grid and those paired with new or existing renewable resources. Qualified bids must be submitted by early 2026 with a preference for projects online before 2031.
