The Escaba dam ( Spanish: Represa Escaba or Dique Escaba ) is a dam with a hydropower plant in the province of Tucumán , Argentina . It dams the Río Marapa to a reservoir. The dam and the associated hydropower plant are also known as the Escaba hydropower plant complex (Spanish Complejo hidroeléctrico Escaba ). The town of Juan Bautista Alberdi is located around 15 km northeast of the dam.
The dam is used to generate electricity and supply drinking water. Construction began in 1943. It was completed in 1948. 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 Tucumán SA on July 3, 1996.
Barrier structure
The barrier structure is a concrete pillar dam of the Ambursen type with a height of 72 m above the river bed (maximum height 83 m). The top of the wall is at a height of 630.75 m above sea level . The length of the wall crown is 262 (or 280) m, its width at the crown is 7.8 m. The volume of the barrier structure is 169,000 m³.
The dam wall has both a flood relief and a bottom outlet . A maximum of 1000 m³ / s can be discharged via the flood discharge, and a maximum of 16 m³ / s via the bottom outlet.
Reservoir
The normal target is between 603 and 629.75 m. With a storage target of 629.75 m, the reservoir extends over an area of around 5.39 km² and holds 113.7 (or 117.19 or 126.1 or 142.5) million m³ of water. The maximum storage destination is 630 m, the minimum 596.92 m.
power plant
The power plant's machine house is about 3 km downstream of the dam on the left bank of the river. The installed capacity is 18 (or 24) MW . The average annual generation is given as 65 (or 69, 72 or 74) million kWh . Annual generation fluctuates: in 2009 it was around 36 million kWh and in 2001 it was 107.57 million kWh. The power plant went into operation with the first machine in January 1955. The last machine was put into operation in April 1960.
The three Francis turbines have a maximum output of 8 MW each and the generators 10 MVA each . The nominal speed of the turbines is 600 min −1 . The fall height is between 115 and 142 m. The flow rate is 21 m³ / s (maximum 21.6, minimum 3 m³ / s). In the switchgear , the generator voltage is increased from 13.2 kV to 132 kV using power transformers.
