S&C Electric Co. is making one of the largest solar and energy storage systems in the United States, and to do so, commissioned a 7-MW/3 MWh battery energy system from LG Chem. Commercial operation of the system will be run by its owner Half Moon Ventures (HMV), a renewable energy company, and will be used primarily by the local municipal utility of the Village of Minster, Ohio.
The battery energy storage system (BESS) and 4.2-MW PV systems are installed in the service territory of the Village of Minster. The BESS provides four distinct revenue streams for HMV and the Village: Frequency regulation; Transmission & Distribution cost deferral; Power quality improvements; and Peak demand shaving. The project is an example of how energy storage provides multiple value streams for numerous stakeholders, while providing end users with improved services and reliability, especially for the 61 million customers served by the PJM Interconnection, a regional transmission organization (RTO) that manages the movement of wholesale electricity in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.
LG Chem delivered an integrated battery solution, battery installation supervision, and commissioning to S&C, which integrated the overall system with the electric grid and provided the power conversion system.
“This project is a key example of how energy storage can generate tangible revenue streams while providing critical grid services,” said Mike Edmonds, president, U.S. Business Unit at S&C. “S&C has been able to deliver a comprehensive energy storage solution through its collaboration with LG Chem and is very proud to be moving the energy storage industry forward.”
“LG Chem is continuing to provide world-class solutions for key customers and projects worldwide,” said Sunghoon Jang, senior vice president, Energy Solution, LG Chem. “Collaboration on this project with S&C has provided not only key learnings, but also a system that provides the community with critical grid services, as well as commercially viable revenue streams for the system owner and local utility. This project shows how the energy storage industry has entered another phase with viable projects for customers and end users.”
