Abstract: For combined heat and power (CHP) generation, also called |cogeneration| in industrial and district heating power plants, there are several options possibly comprising steam turbines, gas turbines and combined gas and steam turbine plants. This paper focuses on those having an electrical output of above approximately 25 MW. Each option has its own specific advantage, depending upon the type of fuel, production costs for electricity and heat, type of cogeneration and output range. Comparisons of economics, the coefficients for power production and the control characteristics show that for most cases the combined cycle plant is the most economical and beneficial solution.

Keywords: cogeneration; combined heat and power; CHP; economic comparison; power plants; energy economics.
