The Balbina Dam (Portuguese: Usina Hidrelétrica de Balbina) is a hydroelectric dam and power station on the Uatumã River in the Amazon Rainforest, Brazil. The location is under the municipality of Presidente Figueiredo jurisdiction, in the state of Amazonas.
It was built from 1985 to 1989 and is managed by Manaus Energia, under the Eletronorte system. The first of five generators began operating in February 1989. The dam has an installed capacity of 250 megawatts (340,000 hp) and floods a 2,360-square-kilometre (910 sq mi) area.
The dam was established to provide a renewable electricity supply to the city of Manaus but was considered by locals a controversial project from the start, due to the loss of forest and displacement of tribal homes grounds. It was also criticized for its expensive construction and maintenance costs. As a result of the methane released from its vast reservoir, proportional to its output, the Balbina Dam emits more greenhouse gases than most coal plants.
