The growth in demand for clean and renewable energy is notorious in several around the world, in view of global projects to reduce carbon emissions and better use of the Earth's natural resources. In this sense, international projections indicate that photovoltaic (PV) systems will reach the highest installed power among the types of electricity generation in the world by 2050. To corroborate with this scenario, Floating Photovoltaic (FPV) systems have been presented as a great alternative for several countries, in view of the diverse benefits, such as increased generation efficiency and reduced evaporation from the body of water where this it is installed. In Brazil, studies already demonstrate the generation potential of this type of PV system. In the Northeast, for example, there are many water bodies that provide the location of PV modules on floats. As a way of contributing to society, this work of course conclusion has the objective of identify the PV generation potential for a FPV plant installed on Boa Esperança hydropowerdam, in which the useful estimate area is 248.30 km². In this context, through data from the UHE in question, which are available on the websites of the Operador Nacional do Sistema(ONS) and the Companhia Hidroelétrica do São Francisco (CHESF), comparisons are made with the results obtained for the FPV plants. Therefore, six scenarios are proposed, in which the first three refer to installations with 480 Wp photovoltaic modules and the othersare related to 665 Wp modules. The three scenarios for each case are defined for areas of 1.64 km², 8.19 km² and 16.39 km², which correspond to 1%, 5% and 10% of the useful area of the water body, considering the percentage intended for spacing between modules for moving technicians. The installed capacity of the scenarios varies between 350.42 MWp and 3,641.78 MWp and the annual generation varies between 675.33 GWh and 7,018.43 GWh. In the chapter of results and discussions, these values are compared with data obtained from Empresa de Pesquisa Energética (EPE), Associação Brasileira de Energia Solar Fotovoltaica (ABSOLAR), CHESF and ONS, and analyzes are made of the impact of different scenarios about distinct aspects of the electricity sector in Brazil, in the Northeast, in Ceará and Piauí.
