defined by DOE as ”a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid” and “can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode.”
Pros
An enabler of grid modernization and integration of Smart Grid technologies, microgrids can significantly increase the preparedness and resilience of our communities and grid.
Cons
Can be challenging to build in a deregulated utility market because of the desire/need to own both distributed generation assets and distribution circuits.
Real Talk
As of today, it is not economically possible to fully build out microgrids across the country. They should be built regionally and tactically, such that during adverse events regional stakeholders can benefit.
