MG Denotes a CHP system that is part of a microgrid, a group of interconnected loads and distributed energy resources (DERs) that can disconnect and re-connect to the utility grid as a single entity, allowing facilities to remain operational during utility outages. A CHP system is considered part of a microgrid if it serves multiple buildings or if it is connected to other DER technologies.

CI Denotes sites that fall into overall Critical Infrastructure (CI) facility application types. These facilities may deliver essential services and functions during natural disasters, emergency events, or grid outages, and CHP may allow the facilities to provide reliable electric and thermal energy to maintain our nation’s security, public health and safety, and support sectors.

Energy Star CHP Award Denotes systems that have earned the Energy Star Combined Heat and Power Award for superior performance. For more information, see https://www.epa.gov/chp/energy-star-chp-awards
