The Salto Santiago Hydroelectric Power Plant is a dam and hydroelectric power plant on the Iguazu River near Santiago in Paraná, Brazil.

[1][2] The power station has a 1,420 MW capacity and is supplied with water by a rock-fill embankment dam.

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).

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.
