Brazil’s energy sector is initiating a new effort to construct additional hydroelectric plants alongside the rising number of solar and wind power initiatives. However, past environmental issues could present political challenges.
Despite over half of Brazil’s electricity being generated by hydro plants, it has been five years since its last significant dam project—the contentious Belo Monte complex in the northern state of Para- was completed.
Belo Monte was among the “mega dams” approved during President Luiz Inacio Lula da Silva’s term over ten years ago.
This decision sparked criticism and led to Environment Minister Marina Silva resigning from his government in 2008.

“We could go back to working on new hydroelectric plants, very carefully,” said Marisete Pereira, head of power generation group ABRAGE.
“That way we could count on these resources to guarantee the security of our energy system,” Pereira added.
“They can pump water to an upstream reservoir when power prices are cheap during the day and generate power later, when demand is greater and prices are more expensive,” said Engie Brasil, opens new tab director Gil Maranhao Neto. “But we still lack regulation for that.”
