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.
Salto Santiago Dam
[edit]The Salto Santiago Dam is 80 metres (260 ft) high, 1,400 metres (4,600 ft) long and is of rock-fill embankment type, comprising 518,200 cubic metres (18,300,000 cu ft) in concrete structure. The dam's spillways contains nine 21.5-metre (71 ft) wide and 15.3-metre (50 ft) wide radial gates and has a maximum capacity of 24,000 cubic metres per second (850,000 cu ft/s). The reservoir formed behind the dam contains 4,094,000,000 cubic metres (3,319,000 acre⋅ft) of total storage with a surface area of 208 square kilometres (80 sq mi) and a catchment area of 43,330 square kilometres (16,730 sq mi). The average flow of the river through the dam is 902 cubic metres per second (31,900 cu ft/s) and the reservoir has a normal operating level of 506 metres (1,660 ft).[3]
Power plant
[edit]The power plant at the southern end of the dam contains four 355 megawatts (476,000 hp) hydroelectric generators powered by Francis turbines. Each turbine has a rated discharge of 346 cubic metres per second (12,200 cu ft/s) and is fed by a 7.6-metre (25 ft) diameter steel penstock which provides a gross hydraulic head of 106 metres (348 ft). 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]
