Georgia Power has started building a 200-megawatt battery energy storage system (BESS) in Twiggs County, southeast of Macon, Georgia. The project is located next to the existing Twiggs County Solar facility and was selected as part of the company’s 2023 Integrated Resource Plan (IRP) Update. The Georgia Public Service Commission approved construction on September 4, 2025.
The new BESS will be able to quickly dispatch stored electricity over a four-hour period. Battery systems like this are designed to improve the reliability and resilience of the electric grid. They also help make better use of renewable resources such as solar power by storing excess energy when demand is low and releasing it during peak times, like cold winter mornings when solar production drops.
Rick Anderson, senior vice president and senior production officer for Georgia Power, said, “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, which is expected to be completed in 2027.
Georgia Power is also working on four additional battery storage projects across Bibb, Cherokee, Floyd, and Lowndes counties. These projects total 765 MW and are expected to be finished in 2026.
As part of an All-Source Request for Proposals (RFP), Georgia Power has requested approval from regulators for ten new battery storage sites with a combined capacity of just over 3 gigawatts. The company has also proposed two new solar systems paired with batteries totaling 350 MW. Site selection considered locations near existing substations or on company-owned land.
Additionally, bids are being sought for another 500 MW of energy storage systems with at least two hours of discharge duration. This RFP process is managed by Ascend Analytics as an independent evaluator for Georgia Power. The company prefers these new resources to come online by no later than 2031; qualified project bids are due in early 2026.
