Energy Efficiency Technologies for Hydroelectric Power Plants: A Case Study in Brazil

Abstract

Hydroelectricity has great importance for the global macroeconomy. In Brazil, hydroelectricity has been highlighted as the main source of generation of the electric system both for its economic competitiveness and for the abundance of this energy resource. Based on a diagnosis methodology, this article presents a case study in a Brazilian hydroelectric plant in order to optimize the use of energy and propose improvements regarding the rationalization of its application. The systems associated with energy generation were evaluated and the results proved to be potentially advantageous with an estimated savings of 2910 MWh/year in the electricity consumption of the installation itself, with better use of the equipment and the possibility of increasing the power generated.
