Perfil da geração hidrelétrica no Oeste e Sudoeste do Paraná

Abstract

Hydroelectric generation is the main source of electricity in Brazil and also in the West and Southwest of Paraná. Year after year the energy matrix has been diversifying, including new sources, such as wind power. However, due to the power accumulation characteristic of hydroelectric plants, this type of source is important for the stability of the electric system. Currently, hydroelectric power corresponds to just over 60% of all power installed in Brazil. Particularly in the West and Southwest of Paraná, this number increases and Paraná's share in the Brazilian matrix is approximately 16% of all installed power. In order to verify the participation of these regions in the hydropower matrix and also their production, a survey was made of the installed potential and the constructive profile of the hydroenergy projects. In addition, the flow and production trends of the Salto Santiago hydroelectric plant in the Iguaçu River basin and the Melissa hydroelectric plant in the Piquiri river basin were verified in the 2003 to 2017 period. Finally, a conceptual map of the western and southwestern regions of Paraná was elaborated with the hydroelectric generation profile. It was noticed by the survey that the regions of the study have great participation in the hydroelectric matrix of Brazil and that its production and the flow of the rivers in the entrance of these remains practically unchanged in the studied period.
