The dam Río Hondo ( Spanish Represa Río Hondo or Dique Río Hondo ) is a dam with hydroelectric power plant in the province of Santiago del Estero , Argentina . It dams the Río Dulce to a reservoir. The dam and the associated hydropower plant are also known as the Río Hondo hydropower plant complex (Spanish Complejo hidroeléctrico Río Hondo ). The city of Termas de Río Hondo is about 2 km northeast of the dam.
The dam is used for irrigation, drinking water supply and electricity generation. Construction began in 1958. It was completed in September 1967. The dam and the hydroelectric power station are state-owned ( Secretaría de Energía de la Nación ). The concession for the operation was transferred to Hidroeléctrica Río Hondo SA on December 29, 1994.
Barrier structure
The barrier structure consists of a gravity dam made of concrete in the middle and embankments that connect on both sides. The height of the gravity dam is 29 m above the river bed (maximum height 39.5 m above the foundation base ); its length is 206 m. The top of the wall is at a height of 277.37 (or 278.5) m above sea level . The total length of the structure is 4347 m. The width of the dams is 216 m at the base and 10 m at the crown. 130,000 m³ of concrete and 8.252 million m³ of bulk material were used for the barrier structure.
The dam wall has both a flood relief and a bottom outlet . A maximum of 1525 m³ / s can be discharged via the flood discharge, and a maximum of 137.3 m³ / s via the bottom outlet.
Reservoir
The normal storage target is between 267.7 and 272 m. With a storage target of 272 m, the reservoir extends over an area of around 20.65 km² and holds 0.96 billion m³ of water. With a storage target of 274 m, the reservoir extends over an area of around 29.67 km² and holds 1.74 billion m³ of water. The maximum storage destination is 275 m.
power plant
The power plant was put into operation in 1976. The power plant's machine house is part of the gravity dam. The installed capacity is 15.2 (or 17, 17.5 or 19) MW . The average annual generation is given as 85 (or 90, 93, or 99) million kWh . Annual production fluctuates: in 2003 it was 105.5 million kWh and in 2006 it was 142 million kWh.
There are two turbines installed; one has a maximum of 8 MW, the other 9.5 MW. The nominal speed of the turbines is 250 min −1 . The fall height is between 14 and 24 m. The flow rate is between 15 and 44 m³ / s.
