The Ranjit Sagar Dam ( English Ranjit Sagar Dam , also: "Thein Dam") is a large multi-purpose dam on the Ravi River , 24 km above Madhopur , in North India .
The structure is part of a plan for the use of the water of the three rivers Satluj , Beas and Ravi for irrigation and hydropower generation.
The Ranjit Sagar Dam is located in a Ravi gorge near the village of Thein in the Jammu and Kashmir union territory in a seismically active zone of the Himalayas , the Shivalik mountain range . The project is a joint project between Jammu and Kashmir and the states of Punjab and Himachal Pradesh , on whose joint borders the reservoir lies. An intergovernmental agreement between these states was signed in 1979, after which work could begin. The main work has been carried out in sections.
The dam is the highest stone rubble dam with an earth core in India and is currently the second highest dam (after the Tehri Dam ) and the seventh highest dam in total in India.
The project includes the following notable details:
- The hydropower plant has four (vertical) Francis turbines with 150 MW each, a total of 600 MW. The height of fall varies between 76.0 and 121.9 m.
It is the sixth largest hydropower plant in India; the individual turbines are the second largest in India.
- The dam is said to have the longest flood relief channel in Asia. The four reinforced concrete tunnels (T-1, T-2, P-1 and P-2) have a diameter of 12 m and a length of 4 km. For the flood relief from concrete, 26 million m³ of rock had to be excavated (also a record for India) and around 1 million m³ of concrete had to be built. The seven radial inlets are 15.57 m by 17.20 m.
- Ventilation has been installed at the flood relief to prevent cavitation, as the water flows here at a speed of 162 km / h.
- The clear inlet width of the flood relief is 109 m at a height of 511.7 m above sea level. It is designed for a discharge rate of 20,678 m³ / s; a total of 24,637 m³ / s can be discharged.
- There are nine vertical shafts up to 126 m deep for water extraction.
- A 1 km long penstock with a diameter of 8.5 m leads to the power plant.
- In the structure, in the subsoil, under the flood relief and on the slopes, there are inspection patrols totaling 6 km in length. Such a passage under an earth dam was built here for the first time in India.
The Indian Prime Minister Atal Bihari Vajpayee inaugurated the dam on March 4, 2001 near the places Pathankot and Shahpurkandi in the Gurdaspur district of Punjab by pressing a button. The damming of the reservoir began on February 15, 1999 and the first electricity was generated from August 2000.
The Ranjit Sagar Dam is named after Maharaja Ranjit Singh , a famous ruler of the Punjab. The reservoir extends behind the dam for 22 km with a maximum width of 5 km and a depth of up to 130 m. The usable storage capacity is 2344 million cubic meters, the total storage space is 3280 million.
Other uses of the dam besides energy generation are: water supply for industry and agriculture, industrial development, flood protection, fishing, reclamation of land in the river valley, development of tourist destinations, economic boom and others.
