The Chivor Dam (Spanish Represa de Chivor , sometimes also referred to as the "Esmeralda Dam") is a dam on the Río Batá (also Río Garagoa ), a tributary of the Río Guavio , in central Colombia . It is located in the Colombian Eastern Cordillera near the towns of Santa María and Tunja in the Boyacá department, about 90 km east-northeast of Bogotá . It was built between 1970 and 1977. The plant is operated by AES Chivor & Cia., A subsidiary of AES Corp.
The reservoir La Esmeralda (Spanish Embalse La Esmeralda ) is fed by the rivers Río Batá and Río Somondoco . The reservoir also receives feed lines from the Río Tunjita , Río Negro and Río Rucio . The catchment area covers an area of 2420 km². The maximum water area is 12.6 km². The reservoir has a length of about 18 km and is at an altitude of about . The storage space is given as 758 million m³. However , this decreases over the years due to sedimentation .
Hydroelectric power plant
The Chivor hydroelectric power station (Spanish: Central hidroeléctrica Chivor Río Langupá , a tributary of the Río Upía . The water is led from the dam to the power plant further to the east via a pipeline approximately 7 km long. This has eight units. Each has a vertically directed Pelton turbine with an output of 125 MW, a speed of 450 / min and an expansion water volume of 20.25 m³ / s. The power plant uses a drop height of 768 m. Below the power station, the water enters the Río Langupá.) is located on the right bank of the
In 2004 there was an unexpected heavy rain event outside of the rainy season. The almost empty reservoir was filled with sediment-rich floods, which also reached the intake structures. Since the hydropower plant was not shut down immediately, the turbines suffered major erosion damage. The system then had to be taken off the grid for 25 days for repair work. The minimum water level in the reservoir for the operation of the power plant has been increased fromto .
