The conversion energy of Geothermal Power plant usually lower than conventional thermal power plant (coal, gas, nuclear, etc). Geothermal power plants conversion efficiency estimation is based on the enthalpy of the produced geothermal fluid. Many of geothermal fluid consist of two phase fluid, steam and brine, usually only the steam can be used to be utilized to generate electricity, as the brine, it will be reinjected back to geothermal reservoir. This what makes one of the causes of why efficiency in geothermal power plant is low, Due to brine energy is not utilized. In order to increase utilization of brine energy, the binary power plant system is proposed, the system converse heat from brine to generate power, however, although the system has proven, it’s not widely used in Indonesia due to reluctancy from geothermal developer as the feasibility to utilize the system is not widely known. This final assignment will be focused on how to develop binary power plant in geothermal field, the engineering, risk and financial issue will be analyzed, the outcomes of this assignment is to give insight on how feasible to utilized binary system.
