"Microgrid" as a term has been around for decades. Its popularity seems to ebb and flow with how local generation costs compare with central utility costs energy costs; which only tells me there is something viable to the concept that just needs to be refined.
Microgrids are a current hot topic in the power generation industry. It feels like you cannot go more than a couple of days without seeing another article on microgrids. And no wonder – a recent Greentech Media report states that the US installed microgrid capacity is expected to grow 115% and reach 4.3GW over the next five years. Outside of the US there is a lot of talk around rural electrification in developing regions – bringing power to remote communities with combinations of clean solar and energy storage to power villages that currently have no power.
