It consists of a 70 m (230 ft) tall gravity dam which diverts water through a 9.5 km (5.9 mi) long headrace tunnel to the power station which discharges back into the Chenab.
The project provides peaking power to the Northern Grid with beneficiary states being Jammu and Kashmir, Punjab, Haryana, Uttar Pradesh, Uttarakhand, Rajasthan, Delhi and Union Territory of Chandigarh.
