The drenching El Nino rains that may replenish Brazil’s hydropower reservoirs will probably miss the nation’s most important dams, now at historic lows as the country endures its worst drought in eight decades.
The weather phenomena that’s causing floods in Brazil’s south won’t travel far enough north to help refill reservoirs in Sao Paulo, Minas Gerais, Rio de Janeiro and Espirito Santo states, where 70 percent of Brazil’s hydropower capacity is located, said weather forecasters Climatempo and Somar Meteorologia.
“There is no hope that El Nino will fill the southeastern water reservoirs,” said Thaize Baroni, a meteorologist at Sao Paulo-based Somar. “It won’t change conditions for this year and it can make it worse, as the region may have even dryer weather in the next few months.”
