Critical Infrastructure icon Critical Infrastructure (CI) sites are those that fall into overall critical infrastructure 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.

U.S. Environmental Protection Agency Energy Star icon 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
