What is Cogeneration?
Cogeneration Power Plant
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 maximize the many
benefits that arise from it, systems should be based according to the heat
demand of the application.
Page 33

33 Strictly confidential – For discussion purposes only
The Cogeneration System, a.k.a.
Combined Heat & Power (CHP)
System, is a Simultaneous
generation of two different forms of
useful energy using one single
primary energy source
Cogeneration System efficiency is
increased to the 80%+ level
compared to the 30-60% level of
