Abstract
Brazil is one the countries with the largest use of renewable energy on its electrical energy matrix worldwide, mainly due to its high use of hydropower plants to generate electrical energy. However, environmental restrictions have increased over past years, limiting the construction of new hydropower plants, mainly those with accumulation reservoirs. Thereby, to increase the generating capacity of electricity generation, the participation of wind power, coal, natural gas thermal power plants, and combined cycle power plants have expanded. Knowing that most of the Brazilian thermal power plants use the wet cooling system, a decrease in water availability can cause interruptions or shut down in the operation of the plant. The water scarcity is caused, mainly by climate changes that can result in water stress, such as the water crisis of 2014-2015, and a region with water stress is more vulnerable to face instability in the electrical generation by thermal power plants. Therefore, this paper analyses the Brazilian thermal power plants operation susceptibility in different regions, with regard water restriction.
