Ponte de Pedra Hydroelectric Plant, Brasile

A drop of 243 meters and a flow rate of 8.7 m³/s to generate a nominal power of 176 MW/h. These are some figures of the Ponte de Pedra hydroelectric plant on the Rio Correntes, between Mato Grosso do Sul and Mato Grosso do Norte in Brazil. The plant guarantees an annual power production of 1,152,816 MW/h.

The cavern power station is 16 meters wide, 56 meters long, and 31 meters high, equipped with three Francis turbines, each with a capacity of 60 MW.

The other main components of the project include: a 200 m artificial diversion tunnel, a 35-meter-high earth and rock dam with a crest length of approximately 1,450 meters; a concrete spillway with an evacuation capacity of 1,050 m³/s, located on the right shoulder and controlled by three radial gates.
