Microgrids can switch away from the main grid and continue to provide power during emergencies like these. This process is known as ''islanding''. Microgrids can also provide power in remote places that have no access to electricity. Microgrids can provide power where bigger grids fail, even in remote areas. Image: Climate X Change.
CHP plays an important role in supporting the energy reliability and resiliency of many microgrids by providing baseload power and heat to connected buildings. According to the U.S. Department of Energy''s Microgrid Installation Database, over 200 microgrids in the United States incorporate CHP, constituting about 35 percent
A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode. Microgrids can improve customer reliability and resilience to grid disturbances.
