Thermoeconomics are key elements for the design and operation of geothermal power plants. It is necessary for the management of energy supply/demand and the efficient use of renewable energy resources. Various geothermal technologies are already available in geothermal fields. These technologies have heterogeneous characteristics and performances; it is therefore necessary to develop a procedure for comparing different equipment by making a techno-economic evaluation. This study proposes a set of simplified indicators that have been defined to simplify the evaluation of technical solutions in the operational phase of the components of a real geothermal power plant in the decision/design phase by using advanced exergoeconomic analysis. The results of the study show that the total operating cost of 1218 $/h becomes 186 $/h with a decrease of 85% as a result of the improvements in the direction of the suggestions of the analysis. The savings potential of the plant is determined as 15%. CO2 emission cost can be reduced by 15% if it can be operated under operating conditions decided in the analysis.
