Usina Hidrelétrica Teles Pires

The Teles Pires Dam is a run-of-the-river hydroelectric dam on the Teles Pires River, 330 km (205 mi) upstream of the confluence with the Tapajós river, on the border of the Brazilian states of Mato Grosso and Pará. The 80-metre (260 ft) dam impounds a 150-square-kilometre (58 sq mi) reservoir (55 square kilometres (21 sq mi) original riverbed and 95 square kilometres (37 sq mi) inundated area), 84% in Mato Grosso state (Paranaíta district) and 16% in Para state (Jacareacanga district).

The dam is part of a planned six-power-plant "Hidrovia Tapajos/Teles Pires" project to create a navigable waterway connecting the interior of Brazil to the Atlantic Ocean. The waterway will consist of six dams on the Teles Pires river—the 53-megawatt (71,000 hp) Magessi Dam, 430-megawatt (580,000 hp) Sinop Dam, 342-megawatt (459,000 hp) Colider Dam, 1,820-megawatt (2,440,000 hp) Teles Pires Dam, and 746-megawatt (1,000,000 hp) Sao Manoel Dam—and the 230-megawatt (310,000 hp) Foz do Apiacas Dam on the Apiacas river. Smaller upstream dams are still in the planning stages.
