From Wikipedia, the free encyclopedia. Cogeneration (also combined heat and power, CHP) is the use of a heat engine or a power station to make both electricity and useful heat at the same time. Conventional power plants emit the heat created as a byproduct of electricity generation into the environment through cooling towers, as flue gas, or by other means.
For small cogeneration plantsâthose that generate anywhere from one to 20 megawatts of powerâbiomass or even methane from garbage dumps can be used as a front-end fuel source, but natural gas is far more common as the primary input.
