The battery energy storage system (BESS) is installed in the service territory of Georgia Power, the largest subsidiary of Southern Company. This project will assess the technology’s ability to enhance the integration of a 1 MW solar PV system in Cedartown, Georgia, and evaluate the grid impacts of the BESS in support of multiple applications, such as load smoothing, peak shaving, and voltage support.

LG Chem successfully executed the project in close collaboration with Southern Company, EPRI, and ABB, who supplied enclosure and power conversion equipment. LG Chem’s role in the project includes supplying the batteries and power conversion equipment, battery installation, commissioning and operations and maintenance.

EPRI will assist with testing and analysis of data from the project to help Southern Company understand how well the BESS works to onboard and discharge energy from the solar farm, in conjunction with other technologies that are part of the project.

This project is strategically important to LG Chem due to the role EPRI plays in the utility industry, as well as the impact Southern Company has as one of the major energy companies in the US.
