The Misicuni Dam ( Spanish Proyecto Múltiple Misicuni or Presa Misicuni ) is a dam with hydroelectric power station in the department of Cochabamba , Bolivia . It dams the Río Misicuni to a reservoir. The dam is located about 35 km north of the city of Cochabamba .
The dam is owned by the Misicuni company . The power plant belongs to the Empresa Nacional de Electricidad (ENDE); but it is operated by the subsidiary Corani . The power plant was officially inaugurated by the President of Bolivia, Evo Morales , on September 7, 2017.
Barrier structure
The barrier structure is a CFR dam with a height of 120 m above the foundation level (112 m above the river bed). The top of the dam is at an altitude of 3784 m above sea level . The length of the dam crest is 434 m. The dam has a flood relief on the left side, through which a maximum of 1220 m³ / s can be discharged.
Reservoir
At the maximum storage target of 3774 m, the reservoir holds 150 (or 180) million m³ of water.
power plant
The power plant has an installed capacity of 120 MW . It is used to cover peak loads and is supposed to generate electricity for 3 to 4 hours a day. Originally, the installed capacity was 80 MW and an average annual production of 217 million kWh .
The three Pelton turbines with horizontal shafts each have a maximum output of 42.77 MW and the generators 49.5 MVA . The nominal speed of the turbines is 600 / min. The nominal voltage of the generators is 11.5 kV . In the switchgear , the generator voltage of 11.5 kV is increased to 115 kV using power transformers. The maximum height of fall is 1019 m. The maximum flow rate is 4.68 m³ / s per turbine.
The power plant is located approx. 20 km from Cochabamba at an altitude of 2737 m above sea level. A 20 km long tunnel (contrary to the actual direction of flow of the Misicuni) leads from the dam, followed by a penstock (length 3.8 km; diameter 1.6 m) to the power plant. At the power station there is a water basin that can store 280,000 m³. The basin serves as a buffer storage, as the water is used for irrigation and drinking water supply after it has passed the power plant.
Others
The cost of building the dam was originally estimated by the IADB at $ 85 million . Once completed, the dam will cost $ 146 million, the power plant $ 142 million, and the tunnel $ 85 million.
