These self-contained “mini power plants” connect onsite power sources such as microturbines, solar PV, wind turbines, fuel cells, reciprocating engines, and battery storage to produce reliable and less-polluting power for nearby buildings.

Microgrids can be connected to larger electricity grids, and in the event of a widespread outage, can disconnect from the main grid to operate independently and supply electricity to homes and businesses connected to the microgrid’s electricity network.
