The highest levels of solar irradiation in the world can be found in northern Chile, with average yearly totals of DNI between 2800 kWh/m² and 3800 kWh/m². In the present study, the techno-economic analysis of a hybrid CSP+PV plant integrated with TES and a Battery Energy Storage System (BESS) at utility scale was conducted. The plant model was simulated at Crucero, Chile using TRNSYS. The dispatch strategy is to deliver a net output of 100MWe to the grid. A parametric analysis varying PV size, solar multiple, TES hours of storage and BESS capacity was carried out. Results show that the hybrid plant can achieve capacity factors over 90% and the BESS allows to exploit the surplus of PV energy. However, the contribution of the BESS to the total generation is only significant for PV sizes above 100MW and for TES capacities lower than 10h. The minimum LCOE obtained with the parametric analysis was 98.46 USD/MWh with a capacity factor of 85% and a configuration with 100MW PV plant, a solar multiple of 2, 12h of TES, but without batteries. Yet, a solutions domain with capacity factors above 90% and LCOE values between 110 and 130 USD/MWh with BESS capacities from 250 to 500 MWh was found. These results show that it is still necessary a higher reduction cost of the batteries to increase the economic feasibility of this concept besides its technical potential, however, the BESS addition allows to provide higher capacity factors and achieving less dumped PV energy.
