Cogeneration

Cogeneration (cogen) through combined heat and power (CHP) is the simultaneous production of electricity with the recovery and utilisation heat Cogeneration is a highly efficient form of energy conversion and it can achieve primary energy savings of approximately 40% by compared to the separate purchase of electricity from the national electricity grid and a gas boiler for onsite heating
