Abstract: In this paper the design performances of a combined and cogenerative plant are compared to the performances corresponding to a situation caused by the constraints coming from both thermal and electrical loads, in tertns ofvarious parameters. These parameters are: the electrical efficiency, the thermal efficiency, the first law efficiency, the second law efficiency, the energy saving index, the electrical index, the equivalent electrical efficiency and the power-to-heat ratio. The results demonstrate that such a comparisoii is important, significant departures of the actual performances from the values calcul ated with the data supplied by the Manufacturer being observed.
