The Salto Santiago Hydroelectric Power Plant is a dam and hydroelectric power plant on the Iguazu River near Santiago in Paraná, Brazil. It is the third dam upstream of the Iguazu Falls and was completed in 1979.[1] [2] The power station has a 1,420 MW capacity and is supplied with water by a rock-fill embankment dam.
It is owned and operated by Tractebel Energia.
The Salto Santiago Dam is high, long and is of rock-fill embankment type, comprising in concrete structure. The dam's spillways contains nine 21.5m (70.5feet) wide and 15.3m (50.2feet) wide radial gates and has a maximum capacity of . The reservoir formed behind the dam contains 4094000000m2 of total storage with a surface area of and a catchment area of . The average flow of the river through the dam is and the reservoir has a normal operating level of .[3]
The power plant at the southern end of the dam contains four hydroelectric generators powered by Francis turbines. Each turbine has a rated discharge of and is fed by a 7.6m (24.9feet) diameter steel penstock which provides a gross hydraulic head of . The remaining two penstocks are intended for future generators with a plant expansion. The first generator was commissioned on December 31, 1980, with another in 1981, two in 1982 the last of which was commissioned on September 16, 1982.[3] [4]
