A comparative assessment of operation of two power plant schemes is presented by usig appropriate mathematical models. The principal scheme incorporates a geothermal hybrid power plant with a traditional water steam boiler and a steam turbine in the upper temperature range, and an ORC turbine loop in the lower temperature range. Operation of the principal scheme is then compared with such of its individual loops, i.e. of the (reference) water steam power plant (energy input from the steam boiler and from the geothermal source) and of the geothermal ORC power plant. Calculations of power and efficiency have been carried out at comparable operation conditions in all considered cases.
