The Pangue dam or the Pangue power plant ( Spanish Central [hidroeléctrica] Pangue ) is a hydropower plant on the Río Bío Bío in Chile . The dam is located in Region VIII , about 100 km southeast of the city of Los Ángeles . The Ralco Dam is about 15 km upstream.
The project to build the dam started in 1993. The Pangue power plant went into operation in 1996. It is owned by Empresa Nacional de Electricidad SA Chile (ENDESA) and is also operated by ENDESA.
Barrier structure
The barrier structure is a gravity dam made of rolled concrete with a height of 113 m. The length of the top of the wall is 410 m. The dam wall has a flood relief with four gates in the middle . A maximum of 8000 m³ / s can be discharged via the flood relief.
Reservoir
When the reservoir is fully blocked, it will hold around 175 million m³ of water.
power plant
With an installed capacity of 467 (or 456) MW , the Pangue power plant is one of the largest hydropower plants in Chile (as of April 2015). The average annual production fluctuates with the water flow of the Río Bío Bío : it was 1.367 billion kWh in 2007 and 2.444 billion kWh in 2006.
The two machines of the power plant were put into operation in 1996. The Francis turbines were supplied by Kvaerner and the generators by General Electric . The turbines have a maximum output of 233.5 MW each. The generators have a nominal voltage of 13.8 kV . In the switchgear , the generator voltage is increased from 13.8 kV to 230 kV using power transformers.
The maximum height of fall is 99.1 m. The maximum flow rate is 500 m³ / s.
Others
The total cost of the power plant amounted to 46 million USD .
