The Floating Photovoltaic Plant (UFVF) can be an alternative to alleviate water supply problems, by reducing the evaporation of water from the reservoir. Another advantage, when compared to photovoltaic plants, is the increased efficiency in electricity generation, as water contributes to the cooling of the plates. This work aims to present an analysis of the sizing methodology used for the implementation of a UFVF and to evaluate the photovoltaic solar generation through the construction of the Permanence Curve (CP) of the Rosário reservoir, municipality of Lavras da Mangabeira - CE. Thus, an analysis of the gains in storage of the water from the reservoir, socio-environmental impacts and opportunities for cost reduction was evidenced. The methodological procedures were based on four steps: obtaining historical data from the dam; construction of the CP referring to the flooded area of the reservoir; choice of reliability levels (90% to 80%) and verification of boundary conditions to determine the UFVF area (UFVF Area), calculation of the UFVF's installed capacity and daily electricity production through the daily values of local photovoltaic productivity. The dimensioning methodology was elaborated from the construction of two scenarios for the production of electric energy. The modules chosen for each scenario are 245 Wp and 275 Wp. The results of the analysis of the implementation of the UFVF Area for the annual production of electricity can reach 470.70 GWh and 612.14 GWh. The total power of the UFVF found in the case study for the chosen scenarios was 286.57 MWp and 372.69 MWp.
