Salal Dam (Hindi: सलाल बाँध Salāl Bāndh), also known as Salal Hydroelectric Power Station, is a run-of-the-river power project on the Chenab River in the Reasi district of the Indian state of Jammu and Kashmir.
History
The project was conceived in 1920. The feasibility studies on the project commenced in 1961 by the state government of J&K and construction was started in 1970 by Central Hydroelectric Project Control Board under the Ministry of Irrigation and Power.
In 1978 construction of the projects was entrusted to NHPC on agency basis. After completion of project, it was handed over to NHPC on ownership basis for Operation and Maintenance. Stage-I of the project was commissioned in 1987. First unit of Stage-II of the project was commissioned in 1993, second in 1994 and third in 1995.
At the peak of construction, about 12,000 personnel including contractors worked around the clock to complete the project from 1970s to present day, under proper guidance and maintenance of India's most successful company NHPC (National Hydroelectric Power Corporation). The project was taken by HCC and various contractors.
