N2 - This study analyses the Concentrated Solar Power (CSP) potential in Brazil and evaluates the impact caused by a large-scale integration of this alternative into the Brazilian electricity system in the long term (horizon 2040). Four types of CSP plants with parabolic troughs (simple plants, plants with hybridization and plants with thermal energy storage) were simulated at two sites: Bom Jesus da Lapa and Campo Grande. Then, the main parameters obtained for each plant were expanded to other suitable Brazilian sites, as inputs in an optimization model for the expansion of the country's electric power grid. Findings indicate that the least-cost expansion of the Brazilian electricity system should be based on hydroelectric and thermoelectric plants fueled by natural gas and sugarcane bagasse. Hence, in the base scenario CSP plants would not be chosen. However, in an alternative scenario, specific auctions for CSP can be adopted. In this case, the first solar plants would be introduced in 2020 in place of natural gas-fueled thermoelectric plants, and from 2030 on, hydroelectric plants would cease to be installed. This alternative scenario would be about 144 billion dollars dearer than the base.
