A expansão da estrutura de hidrelétricas no Sudoeste do Paraná a partir da década de 1970

Abstract

The objective is to analyze the hydroelectric expansion in the Southwest of Paraná, defined by the criterion of geographic region by (IPARDES), according to State Law nº 15.825/08 – Paraná. This, in turn, considers that the Southwest Geographic Region of Paraná includes the municipalities of Palmas, Clevelândia, Honório Serpa, Coronel Domingos Soares and Mangueirinha, totaling 42 municipalities. To achieve this objective, we started with the historical study of the genesis of the Brazilian electricity sector and the formation of the sector's institutional structure. To study the Southwest of Paraná, the historical cut will be from the 1970s, a period marked by the construction and installation of the first hydroelectric plants in the region. Subsequently, an analysis was carried out on the socioeconomic impacts provided by the construction of energy infrastructures in the region. It was therefore found that the economic impacts on municipalities that had part of their territory affected by the construction of hydroelectric projects in the Southwest were significant, in some cases representing 5% of the municipality's annual revenue through financial compensation and or (ICMS) collected. of companies in the municipality. We also concluded that the increase in electricity demand will grow linearly in the coming years, requiring the hydraulic energy matrix to be prepared to absorb such demand. Although the matrices diversify over the years, hydroelectric plants are still fundamental due to the stability they generate in the Electric System.
