LG Chem commissioned a 1 MW/1 MWh lithium-ion energy storage system, integrated with a 1 MW solar PV system in Cedartown, Georgia for Southern Company and the Electric Power Research Institute (EPRI).

The ESS is installed inside the service territory of Georgia Power, the largest subsidiary of Southern Company and will be used to: "evaluate the grid impacts of the BESS in support of multiple applications, such as load smoothing, peak shaving, and voltage support."

Enclosure and power conversion equipment was supplied by ABB.

" 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. "

Haresh Kamath, senior program manager at EPRI said:

“Energy storage is a technology that can enhance grid reliability and make it easier to integrate renewable energy sources. The learning and experiences gained throughout the course of the project are beneficial for moving forward an integrated grid in the U.S. and worldwide.”

Sunghoon Jang, senior vice president, Energy Solution, LG Chem commented:

“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 U.S. The successful commissioning of this project is another example of LG Chem’s capability to collaborate in order to execute and deliver energy storage solutions for the market.”
