The Governor Ney Braga de Barros Hydroelectric Plant, formerly known as Segredo, is a dam and hydroelectric power plant on the Iguazu River near Segredo in Paraná, Brazil. It is the fourth dam upstream of the Iguazu Falls and was constructed between 1987 and 1991 while being inaugurated in 1992.[1][2] The power station has a 1,260 megawatts (1,690,000 hp) capacity and is supplied with water by a concrete face rock-fill embankment dam.
It is owned and operated by Copel who renamed it after Ney Braga de Barros, governor of Paraná between 1961–1965 and 1979–1982. It was the first hydroelectric project in Brazil's history to provide an Environmental Impact Assessment.[3]
