Assessment of Yuntdaǧi hydrothermal system in Dikili-İzmir Region, Western Turkey

For Turkey, one sustainable way to increase the clean energy share in the power generation can be the utilization of geothermal resources. This study aims to investigate the potential of hydrothermal system in Dikili-İzmir to generate power. Accessible resource base and recoverable heat energy are calculated by employing a probabilistic approach-Monte Carlo simulation.A sensitivity analysis is performed for the input parameters related to the heat potential of the reservoir.Based on the existing accessible resource base and recoverable heat in place calculations, with 90% probability, the net electrical power can be produced from Yuntdaǧ reservoir is 30 MW_e. Sensitivity analysis showed that reservoir area, rock-fluid temperature and recovery factor have the greatest impact on net power output.Sustainability attributes of the discussed cases are evaluated in terms of saved CO₂ amount and saved money by employing a domestic energy source rather than an imported one.
