A "microgrid" is a group of interconnected loads and distributed energy resources that can act together as a single controllable entity and can connect and disconnect from the grid to operate in "grid connected" or "island mode." Microgrids are used by local government entities to ensure that critical facilities (such as hospitals, police and fire stations, water and sewage treatment plants and other municipal centers or commercial centers) remain powered during electrical grid outages. Some states, such as Connecticut, offer grants for such projects. In addition to promoting greater reliability and resiliency, a microgrid project can result in energy savings for customers connected to the microgrid. Further benefits can include economic benefits to the host community such as increased property tax revenue from the generating equipment for the microgrid. Depending on the technology used for the microgrid, the municipality may also meet carbon reduction and renewable energy goals.

As a developer of grid-scale and distributed generation projects, the CTE&T team can evaluate the technical feasibility of such projects, select the best equipment and technology for the project, and design, permit and obtain financing for the project.
