CHP (combined heat and power)
Combined heat and power, also called cogeneration, is on-site generation that captures waste heat from producing electricity and puts it to use, for example to drive absorption chillers. Using the heat raises overall fuel efficiency compared with generating power alone. For data centers, CHP is weighed against simpler on-site options based on gas supply, air permitting, thermal demand and how the system fits redundancy goals.
