This paper analyzed the effect of operating parameters of steam condenser on the performance of a geothermal power plant. Based on the inlet steam parameters of one wellhead power plant located in Kenya, the net output power was computed and analyzed at different condensation pressures, and the optimum operating pressure for the steam condenser was presented. This investigation will provide a scientific base for the selection of optimum operating pressures of the steam condenser in geo- thermal power plants.
