Georgia Power has unveiled the sites for its 500 MW of new battery energy storage systems (BESS), as authorized by the Georgia Public Service Commission (PSC) earlier this year. These projects, set to provide reliable and economical electricity during the winter of 2026-2027, will serve as dispatchable capacity resources with a 4-hour duration for each BESS.
Key Project Locations:
Robins BESS (Bibb County, 128 MW): This facility will be co-located with the existing solar plant near Robins Air Force Base. By leveraging existing infrastructure, Georgia Power can avoid constructing new transmission generator step-up (GSU) substations, reducing costs and lead times associated with transmission upgrades.
Moody BESS (Lowndes County, 49.5 MW): Similarly, this project will be situated alongside the solar facility adjacent to Moody Air Force Base, utilizing existing infrastructure to minimize expenses and construction time for new substations and transmission interconnections.
Hammond BESS (Floyd County, 57.5 MW): Located at the retired coal-fired Plant Hammond, this project will repurpose existing infrastructure and identified transmission capacity, offering significant benefits to customers while helping meet Georgia Power’s capacity needs.
McGrau Ford Site Phase II BESS (Cherokee County, 265 MW): This site will allow Georgia Power to expand an existing project-level substation and generation tie line, avoiding the need for new substation construction.
In addition to these projects, Georgia Power is nearing the completion of the 65 MW Mossy Branch Battery Facility in Talbot County. Approved in the 2019 Integrated Resource Plan (IRP), Mossy Branch will be Georgia Power’s first BESS resource. The company is also developing the 265 MW McGrau Ford Phase I BESS project, expected to be operational by the end of 2026.
