A parallel exists with total energy plants, which are typically designed for power demands rather than thermal.

Fuels used in cogeneration facilities may take the form of natural gas, biomass, oil or coal. Most cogeneration systems are designed to simultaneously produce electric power (to be used on site or sold back to an investor-owned utility or both) and thermal heat for industrial processes or the heating and cooling of buildings.
