Microgrids preemptively switch to island mode to safeguard operations. Facilities may intentionally enter island mode for planned grid maintenance, testing, or to avoid high energy costs during peak demand hours. When an outage occurs on the electric grid — whether from a storm, a car hitting a power pole or a substation failure — businesses experience costly. . At its core, island mode is a microgrid's ability to disconnect from the main electrical grid and operate independently.
