LG Chem delivered and installed batteries for a 7 MW/3 MWh system in Minster, Ohio. The battery system has been combined with a 4.2 MW solar PV array as well. The S&C Electric Company provided construction, engineering, battery system integration, and procurements. Half Moon Ventures and the local utility also collaborated on the project.
The system benefits to Minster will be shaving of peak demand, improving power quality, and deferring $350,000 in transmission and distribution costs.
“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,” explained Sunghoon Jang, an LG Chem Senior Vice President.
Minster has a population of about 2,800, so a 4.2 MW solar power system is a large one. According to SEIA, one megawatt of solar power can provide electricity for about 160 homes, with adequate sunshine. A 4 MW system would be able to generate enough electricity for approximately 640 homes, which might cover about half of Minster’s population.
“This project is a key example of how energy storage can generate tangible revenue streams while providing critical grid services. 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,” said Mike Edmonds, president of the U.S. Business Unit at S&C. A press release also said that such energy storage facilities can provide services to the tens of millions of customers served by the PJM Interconnection.
It has also been proposed that a network of such storage installations might eventually allow some peaker plants to be replaced. If those replacements do occur, there should be less climate change emissions.
