Uma análise da sustentabilidade econômica do Projeto de Integração do Rio São Francisco com bacias hidrográficas do Nordeste Setentrional.

Abstract

The São Francisco River Integration Project with Hydrographic Basins in the Northeast of Brazil is currently the largest hydroelectric project in Brazil, built with the purpose of supplying more than 12 million people in 4 states in the Northeast. Considering that the guarantee of operation and maintenance of the work is essential for supplying the population, in addition to being a social and economic transformation agent of the regions served by it, this work investigates the economic sustainability of the enterprise in varied scenarios of available flow . The Total Revenue Revenue and Availability and Consumption Rates were estimated for the full operation of the work, as well as the impact caused by the sanitation rates of the receiving states. The calculation of the financial amount and reference tariffs followed the methodology suggested by the National Water Agency. It was verified that for the scenario of lower flow available, the reference tariffs are higher, causing a greater impact on the sanitation rates of the receiving states, and consequently, the water volume is seen as less onerous for the scenario of higher flow available. It is concluded that to reduce the cost of operation and maintenance, it is necessary to negotiate the electric energy price at the lowest possible value, which is the most representative element in the Total Revenue Required.
