A microgrid is a group of interconnected loads and distributed energy resources that act as a single controllable entity, with respect to the overall grid.

It can connect and disconnect from the main grid to operate in “grid-connected” or “island mode“.

Within microgrids are one or more kinds of distributed energy: solar panels, wind turbines, combined heat & power and generators that produce its power.

Benefits to microgrids are:

• Provide efficient, low-cost, clean energy

• Improve the stability of the regional electric grid and increases reliability and resilience

• Reduce grid “congestion” and peak loads

• Enable highly-efficient CHP (combined heat & power), reducing fuel use and carbon footprint

• Integrate CHP (combined heat & power), renewables, thermal and electric storage, and advanced system and building controls

• Offer grid services including: energy, capacity, and ancillary services

• Support places of refuge in regional crises and first responders

• Use local energy resources and jobs

• Diversified risk rather than concentrated risk

• Using electric and thermal storage capabilities, a microgrid can provide local management of variable renewable generation, particularly on-site solar

• When properly designed, a regional power grid that combines both large central plants and distributed microgrids can be built with: less total capital cost, less installed generation, higher capacity factor on all assets, and higher reliability.
