Although Concentrated Solar Power (CSP) is not large scale deployed in Brazil, it has an important potential in specific regions of the territory. This work analyzes the range of centralized CSP plant configurations with heating storage and hybridization, as well as the vantages of its operation in the National Interconnected System. Two scenarios were analyzed: base and an alternative. The base one is associated to the actual context of incentives, that includes current fiscal scheme and the rules of financers; the alternative scenario incorporates proposals of fiscal and financial incentives. Using the SAM software, it is analyzed the influence of the variation in the heating storage capacity and the annual energy production. The study case was developed in Campo Grande, Brazil, where five CSP plants were simulated (combinations of heating storage and hybridization) for each scenario. According to the input data and to the plant configurations in each scenario, the LCOE values varied between the range of 39.9 – 82.9 cent. USD/kWh in the base scenario and between 19.7 and 39.1 cent. USD/kWh in the alternative scenario.
