Georgia Power has struck a deal with Tesla to build a large-scale battery energy storage system (BESS) portfolio, aiming to enhance grid reliability and address resource shortfalls. The agreement, which includes four separate projects totaling 500MW/2,000MWh, will utilize Tesla’s advanced battery technology, according to Energy Storage News.

Agreement Details

The deal between Georgia Power and Tesla is substantial. It involves a battery and equipment supply agreement (BESA) for a portfolio that includes:

Total capacity: 500MW/2,000MWh
Four separate projects of varying sizes
All projects will use Tesla’s 3.9MWh 2XL Megapack units
Megapacks use lithium-iron phosphate (LFP) battery technology
Batteries manufactured at Tesla’s megapack factory in Lathrop, California

Project Locations and Capacities

The four BESS projects are spread across different counties in Georgia:

Robins BESS in Bibb County (128MW)
Moody BESS in Lowndes County (49.5MW)
Hammond BESS in Floyd County (57.5MW)
McGrau Ford Site Phase II BESS in Cherokee County (265MW)

Timeline and Purpose

The projects are set to provide dispatchable power resources by winter 2026/2027. They aim to address resource shortfalls identified for that period. Georgia Power is seeking expedited approval from the Georgia Public Service Commission to move forward with these initiatives.

Additional Details

Tesla will guarantee consistent battery capacity and maintain round-trip efficiency for the expected 20-year lifespan of the projects. Georgia Power has also entered into EPC agreements with Burns & McDonnell and Crowder Industrial Construction for the projects. The utility intends to pay for construction through its rate base and will utilize any available tax credits from the Inflation Reduction Act, passing benefits to customers.

Context

This agreement is part of Georgia Power’s broader efforts to expand its energy storage capabilities. The utility is also nearing completion of the 65MW Mossy Branch battery facility and developing the 265MW McGrau Ford Phase I BESS project.

EVXL’s Take

The collaboration between Georgia Power and Tesla highlights the growing importance of battery storage in enhancing grid reliability and sustainability. As EV adoption continues to rise, such initiatives are crucial for ensuring a stable power supply. This project aligns with broader trends in the industry, as seen in recent articles on Tesla’s advancements and Lucid’s innovations. These developments underscore the pivotal role of battery technology in shaping the future of electric vehicles and energy storage.
