Department of Energy: Definition of a MicroGrid
A group of interconnected loads and distributed energy resources (DER) with clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid [and can] connect and disconnect from the grid to enable it to operate in both grid-connected or island mode.
How does it work


Why is a microgrid important for Brooklyn?
“Communities are taking an important first step toward securing their energy future. By ensuring a continuous energy supply, medical facilities and communities can more reliably provide critical services and be better protected in the event that disaster strikes. I encourage communities across the state to participate in the NY Prize program to make their energy systems stronger and more resilient.” — New York State Governor Cuomo
“Community microgrids can protect residents and businesses from some of the devastating effects seen after storms like Sandy, Irene and Lee and I’m pleased to see many of cities and towns across New York most impacted by these storms have entered this first phase of the NY Prize competition. Microgrid technology is just one component of the State’s efforts in building an energy infrastructure that is more resilient, reliable and efficient.” — NYSERDA Chairman of Energy and Finance Richard Kauffman
