Off-grid microgrids. Off-grid microgrids are constructed where there is a significant need for electricity but no access to a wide-area electrical grid. Islands that are too far from the mainland are typically served by their own microgrid. In the past, island microgrids were usually built around diesel or heavy fuel oil generators.
But because microgrids are self-contained, they may operate in "island mode," meaning they function autonomously and deliver power on their own. They usually are comprised of several types of distributed energy resources (DERs), such as solar panels, wind turbines, fuel cells and energy storage systems.
