Abstract: The Brazilian electrical system is characterized by being a large-scale system with a majority of hydropower plants. The electrical energy production in hydropower plants is influenced by the reservoir level, which can vary due to natural and human factors. Hydro scarcity caused by the deregularization of rainy periods is an impactful factor in reducing hydraulic potentials. However, using hydro resources when considering cascade hydropower plants maximizes electricity production. Therefore, this study aims to clarify the perspectives of the different energy sources that make up the electrical matrix, highlighting hydropower plants. The main characteristics of hydropower will also be elucidated. Finally, the importance of hydro generation in the Brazilian electrical system is stressed, which in turn provides a more sustainable and efficient energy matrix.
