How does CHP work? A conventional power plant makes electricity by a fairly inefficient process. A fossil fuel such as oil, coal, or natural gas is burned in a giant furnace to release heat energy. The heat is used to boil water and make steam, the steam drives a turbine, the turbine drives a generator, and the generator makes electricity.

1 This fact sheet is focused on topping cycle CHP where fuel is first used to generate power. In a bottoming cycle CHP system, also referred to as "waste heat to power," fuel is first used to provide thermal input to a furnace or other industrial process and heat rejected from the furnace or process is then used for electricity production.
