Abstract

Exergoeconomic performance evaluation of 2700 kW binary cycle design geothermal powerplant in western Turkey is conducted using actual plant operating data, and potential improvements areidentified. Afyon Geothermal Power Plant is thermodynamically modeled in a computer environmentusing current working parameters in a comprehensive way for the use of geothermal energy in electricitygeneration. To simulate the plant during thermodynamic conditions with exergoeconomic analysis, theEngineering Equation Solver (EES) software is used. Geothermal water temperature and mass flow rateof the plant are 110°C, and 150 kg/s, respectively. Energy and exergy efficiencies of the plant are calculatedas 10.4%, and 29.7%. The potential annual revenue of geothermal electricity is calculated to be 2,880,277$/yr. The exergetic cost of the electricity from the plant is calculated as 0.0233 $/kWh, respectively.
