CT: Combined heat and power (CHP), also known as cogeneration, is the simultaneous production of electricity and heat from a single fuel source, such as: natural gas, biomass, biogas, coal, waste heat, or oil.
CHP is not a single technology, but an integrated energy system that can be modified depending upon the needs of the energy end user.

N: 1. From co- (in Latin, the form of com- in compounds with stems beginning in vowels and h- and gn-; taken in English from 17c. as a living prefix meaning “together, mutually, in common,” and used promiscuously with native words and Latin-derived words not beginning with vowels, sometimes even with words already having it) and generation (early 14c., “body of individuals born about the same period” (usually 30 years), from Old French generacion (12c.) and directly from Latin generationem (nominative generatio) “generating, generation,” noun of action from past participle stem of generare “bring forth”).
2. Cogeneration (Combined Heat and Power or CHP) is the simultaneous production of electricity and heat, both of which are used. The central and most fundamental principle of cogeneration is that, in order to maximise the many benefits that arise from it, systems should be based on the heat demand of the application. This can be an individual building, an industrial factory or a town/city served by district heat/cooling. Through the utilisation of the heat, the efficiency of a cogeneration plant can reach 90% or more.
3. Cogeneration therefore offers energy savings ranging between 15-40% when compared against the supply of electricity and heat from conventional power stations and boilers.
