Cogeneration or combined heat and power ( CHP) is the use of a heat engine [1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover ...
