What is a Micro-Grid?
Micro-grids are advanced electric grids, with features that make them especially adept at managing energy and ensuring its reliable delivery. A self-sufficient local energy plant, a micro-grid serves a discrete geographic footprint, examples include manufacturing facilities, college campus’, hospital complexes, business centeres, public offices, or neighborhoods. Most advanced designs, allow for the facility to be totally independent of the local utility grid, giving the facility the ability to be “fully operational” when the surrounding utility- based grid, is offline due to “man-made or natural” events.
A micro-grid contains one or more distributed energy resources (solar panels, wind turbines, combined heat & power generators). In addition, many newer micro-grids, contain energy storage, typically from batteries, as well as electric vehicle charging stations.
Interconnected to nearby buildings and/or superstructure, the micro-grid provides electricity and possibly heating and cooling for its customers, delivered via sophisticated software and control systems. Some advanced micro-grids are also connected to the central utility grid, from which, they buy and sell electricity, creating price efficiencies and sometimes revenue for their hosts.
