en.Wedoany.com Reported - On August 11, Hindustan Construction Company (HCC) disclosed that it has been awarded a contract valued at INR 524.17 crore by NHPC Limited for the rehabilitation and retrofitting of the undersluices of the concrete dam at the Salal Hydropower Station in Jammu and Kashmir, with a contract execution period of 27 months.

The contract includes civil works, hydro-mechanical works, and related auxiliary and construction support works, with the objective of restoring the full functionality and operational capability of the concrete dam undersluices. HCC stated that the project implementation will improve dam operational efficiency and sediment management capacity, and further enhance the long-term safety and reliability of the hydraulic structures.

The Salal Hydropower Station is located on the Chenab River in the Reasi district, with a total installed capacity of 690 MW, equipped with 6 turbine-generator units of 115 MW each. Among them, 3 units of Phase I were commissioned in 1987, and 3 units of Phase II were commissioned in 1995.

According to previously published information by NHPC, the Salal reservoir is approximately 22 kilometers long, with an original designed total storage capacity of 284.08 million cubic meters. After decades of operation, continuous deposition of silt, sand, and other particulate matter has reduced the current effective storage capacity of the reservoir to approximately 13.95 million cubic meters. NHPC regards sediment deposition as an important issue affecting power station operational efficiency and long-term operating conditions, and has already initiated solicitation of reservoir sediment removal schemes and related remediation efforts.

The primary subject of this contract is the concrete dam undersluices of the Salal Hydropower Station and their associated civil and hydro-mechanical facilities. Publicly available information has not yet indicated that main power generation equipment such as turbines and generators are included in the scope of this contract.
