A 1 MW/2 MWh battery energy storage system powered by LG Chem batteries has been commissioned for Southern Co. and the Electric Power Research Institute at a solar photovoltaic facility in the Southeastern region of the U.S.
The battery energy storage system is installed in the service territory of Georgia Power, the largest unit of Southern Co. 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 battery energy storage system in support of multiple applications, such as load smoothing, peak shaving, and voltage support.
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 battery energy storage system works to onboard and discharge energy from the solar farm, in conjunction with other technologies that are part of the project.
“Energy storage is a technology that can enhance grid reliability and make it easier to integrate renewable energy sources,” said Haresh Kamath, senior program manager at EPRI. “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.”
“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.,” said Sunghoon Jang, senior vice president, Energy Solution, LG Chem. “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.”
