CHP combined heat and power

Cogeneration or combined heat and power is the simultaneous production of electricity and heat. The heat produced from the electricity generating process (for example from the exhaust systems of a gas turbine) is captured and utilized for both industrial and domestic purposes e.g. in district heating. This energy, which represents around two thirds of the original primary energy, is wasted in many power stations. CHP increases energy efficiency and environmental compatibility.
