Most microgrids in operation today are essentially retrofit projects that cobble together existing assets and derive revenue from an overlay of controls used to enable legacy technology (consisting of the majority of the assets within the microgrid) to talk to new technology (usually small amounts of solar PV or a new advanced energy storage unit). Today, though, microgrids are beginning to move more into the mainstream, with a greater focus being placed on viable business models. The result is a microgrid market that is much more robust than it was only 5 years ago. New vendors keep entering this space and previously undiscovered projects keep coming to the fore.
As of 4Q 2013, Navigant Research has identified a total of 4,148 MW of total microgrid capacity throughout the world, up from 3,793 MW in the previous Tracker update in 2Q 2013. North America is still the world's leading market for microgrids, with a planned, proposed, and deployed capacity of 2,712 MW, accounting for 65% of global microgrid capacity. This represents an additional 34 projects and 207 MW since the 2Q 2013 update. Of the total North American microgrid capacity, 1,503 MW is currently online and 1,224 MW is in the planned/under development or proposed phase.
This Navigant Research Tracker report provides data on known microgrid projects in the proposal, planning, and deployed stages, including details on the various technologies employed in individual projects. Specific information is provided on the capacity of the following generation assets: diesel, combined heat and power (CHP), solar PV, wind, and fuel cells. The Tracker also details the rated capacity, duration, and types of energy storage for each project and segments data by world region.
