The Ilha Solteira Dam is an embankment dam on the Paraná River near Ilha Solteira in São Paulo, Brazil. It was constructed between 1967 and 1973 for hydroelectric power production, flood control and navigation.[1]

The dam supports hydroelectric power plant with an installed capacity of 3,444 megawatts (4,618,000 hp). The power plant contains 20 generators with Francis turbines that are broken down into three ratings: 11 X 170 megawatts (230,000 hp), 5 X 174 megawatts (233,000 hp) and 4 X 176 megawatts (236,000 hp). In 2005, the power plant produced 17.9 billion kWh of electricity.[2][3]
