The share of global energy produced by microgrids – mini independent power grids created from several power sources working in parallel or independently from the main electricity grid – is growing rapidly. This year, for the first time, the energy added by such new distributed generators will exceed that added by new centralised power plants, according to Navigant Research, a US consultancy. By 2026, according to the consultancy’s projections, the ratio of new power supplied by microgrids to new centralised capacity will be more than three to one. At that point, the global market for hardware, system controls and integration with existing grid infrastructure will be worth $26bn. Ensuring that there is a resilien t power grid in the face of extreme weather events has been a driving force behind microgrids in the US. While California has seen the largest number of power outages for each of the past nine years, other US states are catching up, according to the Eaton Blackout Tracker which explores the causes and effects of power cuts.
