Cogeneration , also called Combined Heat and Power (CHP) is the technology that converts gas into both electricity and heat in a single process at the point of use. The waste heat from the Cogeneration engine is recovered and transformed into useful heat for comfort heating, domestic hot water, process heat or other heating requirements. Combined heat and power produces low carbon and cost effective electricity, with free heating
Trigeneration is the combination of a Cogeneration system and an Absorption Chiller which converts gas into electricity, heating and cooling. The waste heat from the Cogeneration system is converted into chilled water for air conditioning, refrigeration or other cooling purposes.
On site electricity generated by a Cogeneration and Trigeneration system is cheaper and cleaner than coal-fired grid-supplied electricity. Cogeneration and Trigeneration thereby provides substantial cost savings, significantly improved energy efficiency and lower carbon emissions
