The paper presents ways of determining the thermodynamic characteristics of a CHP plant with a gas turbine. Special attention has been paid to the average annual efficiency of transforming the chemical energy of fuel into electricity and heat (the so-called Energy Utility Factor – EUF) and Primary Energy Savings (PES). Two different systems were analyzed, viz. the installation of a gas turbine with a waste-heat boiler and a heat and power generating plant. Concerning the former one the influence of the parameters of steam (temperature and pressure) generated in the waste-heat boiler on the values of PES and EUF was determined. Concerning the latter one, the methods of investigating the effect of the thermal power of heat exchangers on the characteristics have been presented. This will facilitate the proper choice of heat exchangers.
