For large sites, like an industrial facility or a large hospital, a power outage can be very costly. Stopping a process may have critical consequences for production losses, but also for the process restart. That’s why installing a microgrid, which supplies critical loads even during a blackout, is essential.
Some industrial sites, like mines or drilling rigs, can be situated in remote areas with no access to the main grid. These sites need to set up their own local energy production system - an islanded microgrid generating energy locally. Such microgrid system needs to be constantly balanced in real time with the help of local control, however as soon as the grid infrastructure has been sufficiently developed, it should get connected to the main grid.
