The binary power plant is a geothermal power generation system used at low to medium temperature levels, water and steam from the reservoir are not in direct contact with the turbine. In this system, the heat generated from the reservoir is channeled to the secondary working fluid which has a lower boiling point than water using a heat exchanger. In this case, the Organic Rankine Cycle (ORC) is a suitable system for use in this condition. The ORC system can improve the performance and efficiency of binary power plants. However, in this system, the installation configuration of the ORC system model is an important factor that can affect system performance. The selection of an improper ORC design will reduce the thermal efficiency of the system, so it cannot utilize heat optimally. In this study, Engineering Equation Solution (EES) simulation program is used to run the system as in operation conditions. Comparative analysis using ORC, Regenerative ORC (RORC), and RORC with Internal Heat Exchanger (IHE). The results of this study indicate that RORC with IHE has the greatest value, both energy efficiency values (21.74%) and exergy efficiency (25.26%) and net power produced 5479 kW. It shows the addition of OFOH and IHE can increase energy efficiency, exergy, net power, and better performance and reduce energy degradation from the cycle.
