Authorized by the Georgia Public Service Commission, these new systems are part of the state-regulated Integrated Resource Plan (IRP) to stabilize grid performance during demand fluctuations and enhance the integration of variable renewable generation. Energy will be stored during low-demand periods and dispatched during high-demand hours, particularly in winter when grid stress is most pronounced.
Georgia Power’s siting strategy maximizes the use of current infrastructure to manage both costs and deployment speed. The Robins project in Bibb County (128 MW) and the Moody project in Lowndes County (49.5 MW) are co-located with solar facilities near military bases, cutting out the need for new transmission step-up substations and simplifying the interconnection process.
In Floyd County, a different approach is being piloted. The 57.5 MW Hammond battery installation will repurpose the site of a former coal plant—one of several ways Georgia Power is exploring the transition from fossil fuels to cleaner energy assets.
Looking beyond the current slate of projects, Georgia Power is planning for an additional 1,000 MW of battery capacity through a competitive procurement process. A 13 MW demonstration site is also being developed at Fort Stewart near Savannah, further extending the company’s geographic reach.
The utility is also turning its attention to distributed storage solutions. The 2025 IRP includes a pilot program for 50 MW of customer-sited solar-plus-storage, aimed at residential and small commercial participants. This will operate alongside updates to the existing Customer Connected Solar Program, opening up new pathways for consumer involvement in energy storage.
The projects reflect a broader industry trend. As renewables grow, flexible storage is becoming a core component of grid planning to meet energy needs, while ensuring the system remains balanced and resilient in the face of shifting demand and supply patterns.
