It has 14 aircraft units with Kaplan turbines and generators with a total installed capacity of 1551.2 MW in two groups. In addition, auxiliary units are installed with 4.75 MW in each group. The hydropower plant is currently about the tenth-largest in Brazil. It went into operation in 1968.

The shut-off is a combination of earth and rockfill dam on both sides and a gravity dam in the middle. The dams are 2385 m plus 2070 m long, the dam 1040 m, 5495 m together. Another indication of the total length is 5604 m. The height difference of 23 m is overcome by the shipping in a lock. The waterway on the Rio Tietê can be reached from the reservoir from.
