Effect of climate change on the water regime of the Belo Monte and Tucuruí hydroelectric dams
47% of all energy produced in Brazil comes from renewable sources, with hydroelectricity being the main source of electricity. Therefore, in Brazil, electricity generation is highly dependent on climatic conditions. However, when planning electricity generation, the existing dependence on climate change is not taken into account. The greatest generation potential based on hydroelectric plants is found in the Amazon region, with great pressure to materialize new projects in this geographic area. However, these new proposals do not assess the impact that climate change can have on future energy production. In addition, in the production of hydroelectric plants in operation in this region, such as the Belo Monte and Tucuruí HPPs, the possible impact of climate change on their water regime is also disregarded. Thus, the objective of the present research is to analyze the energy production of these hydroelectric plants taking into account projected flow data through the precipitation predicted by climate models that consider climate change. The methodology used is based on the analysis of the pluviometry and fluviometry of the hydrographic basins involved using appropriate climatic and hydrological models.
