What Is CHP? | US EPA

CHP is a technology that produces electricity and thermal energy at high efficiencies using a range of technologies and fuels. With onsite power production, losses are minimized and heat that would otherwise be wasted is applied to facility loads in the form of process heating, steam, hot water, or even chilled water.
