In a combined heat and power plant (CHP plant or co-generation
plant), heat and power are produced simultaneously in the same
power plant process. The greatest benefit of a CHP production is a
high total efficiency: up to 90% or more of the fuel input is converted
to useful energy (heat and power). Due to this an average of
25% less fuel is needed compared to a situation where heat and
electricity are produced in separate plants [1]. Heat and power are
produced in CHP plants both in industrial and municipal power
