Foz do Areia is a reservoir with a hydroelectric power station on the Rio Iguaçu in Brazil . The dam is designed as a rubble dam with a concrete seal on the water side ( CFR dam ).
The hydropower plant was initially expanded with four turbines with an output of 4 × 418.5 MW = 1674 megawatts. The total output in the final stage should be 6 × 418.5 MW = 2511 MW. The Francis turbines with vertical axis are designed for a normal flow rate of 304 m³ / s; the maximum flow is 349 m³ / s.
The catchment area is 29,800 km² and generates an average discharge of 544 m³ / s (averaged over the years 1931 to 1975).
