The Antuco power plant ( Spanish Central [hidroeléctrica] Antuco ) is a hydroelectric power plant on the Río de La Laja in Chile . The power plant is located in Region VIII , approximately 90 km east of the city of Los Ángeles . The volcanoes Antuco and Sierra Velluda are located approx. 25 km southeast of the power plant. The shut-off structure for the Quilleco and Rucúe diversion power plants is located about five kilometers downstream .
The project to build the power plant began in 1974. It went into operation in 1981. Antuco is owned by Empresa Nacional de Electricidad SA Chile (ENDESA) and is also operated by ENDESA.
Barriers
Río Polcura
A dam (Spanish: Bocatoma Polcura ) was built on the Río Polcura about 3.6 km below the outlet of the El Toro power plant, which dams the Polcura into a reservoir with a volume of 1 million m³. The dam has a length of 152 and a height of 26.5 m. A concrete-lined tunnel (length 4970 m, diameter 6.6 m) with a capacity of 160 m³ / s goes from the dam.
Río Laja
On the Río de La Laja , about 450 m below the outlet of the Abanico power station, a dam (span. Bocatoma Laja ) with a length of 150 m was built, which the water of the Laja through canals and tunnels with a total length of more than 6500 m and one Capacity of 50 m³ / s.
Others
In addition to the two barrier structures at Polcura and Laja, there are two other, smaller dams on the Río Pichipolcura and the Estero El Toro , which direct the water via tunnels to the respective main tunnels.
The two main tunnels combine to form a common tunnel (length 7.6 km, diameter 7.1 m), which is followed by the fall zone. There is the moated castle (height 80 m, diameter 6.5 m). The water is then fed through two pressure pipes (length 500 m, diameter 5 m) to the power plant's turbines.
power plant
The Antuco power plant has an installed capacity of 320 (or 324) MW . The average annual production fluctuates: in 2000 it was 1.353 billion kWh and in 2003 it was 1.887 billion kWh.
The two machines of the power plant were put into operation in 1981. The Francis turbines have a maximum output of 160 (or 162) MW each. The data of the originally planned machines were: output 150 MW and nominal speed 250 / min; Nominal voltage of the generators 13.8 kV . Both the turbines and the generators were supplied by Hitachi . In the switchgear , the generator voltage of 13.8 kV is increased to 220 (or 230) kV using power transformers. A double line leads from the switchgear to the El Toro power station and a single line to the Charrúa substation .
The fall height is 190 m. The maximum flow rate is 200 m³ / s.
Others
The total cost of the power plant amounted to 504 million USD (excluding finance costs). The IDB granted a loan of $ 75.3 million on August 9, 1974. The Austrian BAWAG granted a loan of ATS 182 million .
