The Boa Esperança Reservoir (Portuguese Barragem de Boa Esperança ; German “Good Hope”) is a reservoir on the Rio Parnaíba with a hydroelectric power station . The power plant, the Usina Hidrelétrica de Boa Esperança , uses four Francis turbines to generate electricity for the Brazilian state of Piauí . The hydroelectric power station used to be called Usina Hidrelétrica Marechal Castelo Branco . The operator of the hydropower plant is the company CHESF , Companhia Hidrelétrica do São Francisco, also known as Eletrobras Chesf.
The barrier structure, a heaped up dam , is located in the municipality of the municipality of Guadalupe . Construction began in 1964 and it took six years to complete.
The Parnaíba forms the border between the states of Piauí and Maranhão throughout the reservoir and beyond . The storage volume of the reservoir is 5100 million m³. The size specifications for the area are contradictory: the lake area should be 352.2, 384 or even 1800 km².
