Georgia Power has started construction on a new 200-megawatt battery energy storage system (BESS) in Twiggs County, located southeast of Macon, Georgia. The project was selected through competitive processes 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 new facility will be situated next to the existing Twiggs County Solar installation.
The BESS is designed to quickly release stored energy over a four-hour period. Battery storage projects like this one are intended to improve the reliability and resilience of the electric grid and enhance the value of renewable resources such as solar power. By storing excess energy produced during times of low demand, these systems can supply electricity when demand increases, for example during cold winter mornings when solar generation is not 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 handling construction of the Twiggs BESS, which is expected to be completed in 2027.
In addition to this project, construction is underway on four other BESS facilities across Bibb, Cherokee, Floyd, and Lowndes counties. These projects have a combined capacity of 765 MW and are scheduled for completion in 2026. All were approved as part of the same IRP update.
Georgia Power has also proposed ten new BESS facilities totaling over 3 gigawatts of capacity and two new solar-plus-storage systems totaling 350 MW. Site selection focused on deployment capabilities at company-owned sites or near substations.
The company is seeking bids for an additional 500 MW of energy storage systems with at least two hours of discharge duration. This request for proposals (RFP), managed by Ascend Analytics on behalf of Georgia Power, includes both standalone ESS with grid charging capability and ESS paired with renewable resources. The target is for these projects to be operational by no later than 2031; bids are due in early 2026.
