Technical and economic study for the integration of parabolic trough collectors coupled to a binary cycle

In this paper, the preliminary technical and economic study for the integration of parabolic trough solar collectors to a geothermal binary cycle plan is presented, in order to maximize the use of medium enthalpy geothermal resource. It is proposed the use of solar collectors to increase the geothermal brine temperature and achieve design temperature of the plant. A study was conducted to determine the main features of the solar field and its coupling with binary cycle power plant. Subsequently, the thermodynamic models were established in order to obtain the main parameters of the hybrid plant. Additionally, a study was conducted to determine the economic feasibility of the plant including the determination of the levelized cost of electricity (LCoE).
