A microgrid is a general term used to describe a local electricity network (incorporating generators, distribution and end-use) which has the control systems in place to allow it to operate autonomously. In other words it isn’t reliant on connection to a wider national or other “macro” grid (even when – as is commonly the case – such a connection exists for use when it’s more economic to tap into that external resource).

Microgrids come on a wide variety of scales, up to some that are not that “micro” at 10’s of MW in size!

Applications include university campuses, hospitals, military bases and a wide variety of other situations in which the ability to operate independently and/or use local generation sources can provide important reliability, resilience and/or economics benefits.
