Additional information

The project was funded by NY Prize – Feasibility Grant with $100,000.
Planned for the East Hampton area, the Long Island Community Microgrid Project aims to achieve nearly 50% of its grid-area electric power requirements from local solar and sets the stage to avoid hundreds of millions of dollars in transmission investments that otherwise would be required to deliver power to the region. The result will be an optimized local energy system combining up to 15 MW of solar power with a 25 MWh energy storage system. The renewables-based solution will also provide backup power to critical loads, including two Suffolk County Water Authority water pumping and filtration plants and the Springs Fire District facility, during outages.
