What is a microgrid?

A microgrid is a system which links electrical loads and distributed generation sources, and is able to operate both connected to the national grid and autonomously (in so-called “island” mode).

Low environmental impact microgrids that integrate renewable energy generation and electricity storage systems (such as batteries) are becoming increasingly widespread thanks to:

  • their benefits in terms of environmental sustainability;
  • the falling costs of energy storage technologies (e.g. batteries) and renewable energy generation systems (e.g. photovoltaic systems);
  • the development of intelligent control systems which allow the active management of electrical loads and stored electricity, and which, essentially, result in a reduction in energy supply costs.
