Around 99,8% of the Brazilian population has access to electricity, according to data released by IBGE (Brazilian Institute of Geography and Statistics), in 2022. Despite the evolution in energy supply, climate change has intensified and the occurrence of extreme weather events has been causing damage to the country's electrical systems.
In 2024 alone, the country faced the most intense period of drought in recent history, while at the same time facing extreme rainfall and storms that intensified, becoming stronger and more frequent in recent years. The data comes from a survey by Cemaden (National Center for Monitoring Natural Disasters).
With an electrical matrix that is 46,7% supplied by hydroelectric plants, the lack of rainfall directly affects the levels of reservoirs that have their generation capacity reduced.
Strong storms, with gusts of wind and falling trees, cause damage to the overhead power grid, affecting cables, wiring and electrical equipment that are prone to short circuits, explosions and fires. In addition to material damage, they pose risks to life and interruptions in the power supply.
During the year, climate events such as floods in Rio Grande do Sul affected more than 400 municipalities, leaving 147 dead and more than 400 thousand people without electricity.
In addition, the RMSP (São Paulo Metropolitan Region) faced two major blackouts: in March, with thousands of residents without power for more than seven days, and the blackouts in October that affected more than 3 million consumers.
A Fecomercio-SP (Federation of Commerce of Goods, Services and Tourism of the State of São Paulo) pointed out that gross losses in the retail and services sectors totaled more than R$ 1,65 billion. AGU (Attorney General's Office) filed a public civil action against the energy company, which will have to pay R$1 billion in compensation.
In a note, the ENEL stated that due to wind gusts of up to 107 km/h, which caused damage to the electrical grid, around 18% of its consumer base was impacted.
