Combined heat and power (CHP) generation (cogeneration)
Conventional electricity generation plants dissipate waste heat via cooling towers.
Energy efficiency can be significantly improved where the heat from combustion of fuels can also be captured and utilized through combined heat and power generation, where the heat can be used for space heating or in industrial applications.
Large scale CHP technologies (>2 MWe) generally utilize steam or gas turbine generating technologies, but smaller scale developments, where heat output is typically the primary driving requisite, utilize a range of technologies in the drive to maintain energy conversion efficiency. Overall, energy conversion efficiencies of around 85% are possible with CHP operations.
