A microgrid is a small electric system that combines local energy resources and control technologies to provide power to a defined area. Microgrids typically remain connected to the main grid, but they can operate independently.
A microgrid may be small compared to the rest of the electric grid, but its benefits are huge. North Carolina’s electric cooperatives are leading the state and nation with two cutting-edge microgrid projects that bring benefits to cooperative members and test new technologies to lead cooperatives into the future of energy.
The Ocracoke Island microgrid, located on North Carolina’s Outer Banks, was installed in 2017 in partnership with local cooperative Tideland EMC. It adds resiliency and renewable resources to the grid with solar, battery storage and demand response.
The Butler Farms microgrid, located in Lillington, N.C., is an agricultural microgrid developed in partnership with South River Electric Membership Corporation that integrates biogas generation, solar, battery storage.
