Georgia Power’s 2025 Integrated Resource Plan (IRP) filed with the Georgia Public Service Commission (PSC) anticipates approximately 8,200 megawatts (MW) of electrical load growth by 2030 – an increase of more than 2,200 MW compared to projections in its 2023 IRP update, which called for the construction of a swath of new battery energy storage systems (BESS) to help answer the call of data centers and mass electrification.

In that filing, Georgia Power signaled its intention to solicit bids for more storage- another 500 MW- in the near future. Battery energy storage projects are popping up all over the U.S., which added nearly 4 GW of storage capacity in the second quarter of this year alone, according to a recent report.
Georgia Power breaks ground at the McGrau Ford Battery Facility in Cherokee County on April 4, 2025. This 530-megawatt battery energy storage system will consist of two phases, approved in the 2022 Integrated Resource Plan (IRP) and 2023 IRP Update. Courtesy: Georgia Power.
Earlier this month, Georgia Power Company submitted its 2023 Integrated Resource Plan Update (2023 IRP Update) to the Georgia Public Service Commission, which includes an Application for Certification for four battery energy storage systems totaling 500 MW.
Georgia Power included attachments with information and data on each of the proposed projects, but since they contained “sensitive terms and conditions” and cost information, they were nearly entirely redacted from public disclosure- deemed “trade secrets.” Here’s what we do know about those projects:
In February 2024, Georgia Power installed its first grid-connected BESS, the Mossy Branch Energy Facility, a 65 MW system on a couple of acres of rural countryside in Talbot County, north of Columbus, GA. It was approved as part of Georgia Power’s 2019 IRP.
Georgia Power’s fleet of hydroelectric generating units is another source of emission-free energy, with some units serving the state of Georgia for more than 100 years.

Superconducting energy storage systems utilize superconducting magnets to convert electrical energy into electromagnetic energy for storage once charged via the converter from the grid, magnetic fields form within each coil that is then utilized by superconductors as magnets and returned through power converters for use elsewhere when required – like back into grid power or loads via power converters that manage the exchange.

In 2023, the new energy storage power station project will be put into operation, and a one-time reward will be given in the form of a post-event subsidy, and the investor will be given a post-event subsidy of not less than 0.15 yuan/kWh according to the grid-connected time node and discharge capacity, with a maximum reward of 3 million yuan for a single project.

Prominent systems include pumped hydro storage, which involves using gravity to store energy in water reservoirs; 3. battery storage solutions, offering rapid response times and modular design; 4. compressed air energy storage that utilizes underground caverns for energy storage; 5. flywheel systems, which provide instant power through rotational energy; 6. thermal energy storage, where heat is captured for later use; 7. these technologies significantly contribute to the efficient and reliable operation of power stations, facilitating the integration of renewable sources into energy systems.
