All three simultaneously produce electricity and useful thermal energy from a single energy source, such as natural gas, biomass, coal, or waste heat.
The University of Massachusetts Amherst, Cornell University and National Institutes of Health CHP systems achieve operating efficiencies ranging from 76% to 79%.
By designing more efficient facilities, the three award winners have prevented carbon emissions equivalent to the annual emissions from more than 29,000 passenger vehicles, says the EPA.
Established in 2001, the
EPA CHP Partnership
is a voluntary programme that encourages the use of CHP to reduce the environmental impact of power generation.
The partnership works closely with energy users, the CHP industry, state and local governments, and other energy stakeholders to facilitate the development of new projects and to promote energy, environmental and economic benefits.
