Análise da contratação de energia de fontes termoelétricas na composição do sistema interligado nacional

Abstract

Along the years 2011 to 2013, the National Interconnected System underwent some changes, one related to increased hiring by thermoelectric energy sources. Thus, this study aims to examine the motivations and implications of employing thermoelectric energy sources in the composition of the National Interconnected System. To this end we applied study is of exploratory nature, adopting quantitative and qualitative approach. From the literature review and specific documents, particularly reports of the monthly bulletin of the Brazilian electricity sector, we sought to identify factors that led to increased hiring of thermal sources in the period 2011 to 2013. After these procedures it was found that motivations that led to the hiring of thermal sources in the National Interconnected System are related to issues of energy security; increased Gross Domestic Product (GDP); and lesser rainfall. Likewise, highlighted implications are: higher costs for the production and supply of energy; amplified environmental impacts; and no focus on long term investment on electrical energy.
