Abstract
The Jammu & Kashmir State Power Development Corporation (JKSPDC) is contemplating for construction of different run of the river schemes on Dras – Suru Rivers to harness the power potential of these rivers. The Pre-feasibility Stage geotechnical and geological investigation of three hydroelectric projects across the Dras and Suru Rivers were carried out. These proposed projects, named as Dras-Suru link HEP Stage-I, Dras-Suru link HEP Stage-II and Karkit Hydro Electric Project, are all run of the river schemes. The Dras-Suru link HEP Stage-I envisages construction of a low height dam near Dras Town across the Dras River downstream of the bridge connecting the road to Sanko with the Srinagar – Leh national highway and an underground powerhouse near Dongchik village. The length of the proposed HRT is 8 km. and the estimated power potential is 45 MW with 110 m head and 50 cumecs designed discharge. The Dras-Suru link HEP Stage-II envisages construction of a low height dam / barrage across Dras River upstream of Dandal village and an underground powerhouse at village Pheruna along Suru River. The length of the HRT is 9.36 km. and the estimated power potential of the project is 70 MW with 150 m head and 50 cumecs designed discharge. All the project components of these two projects are located within Dras Volcanic Formation comprising mainly basalt and andesite in association with geosynclinals sediments. The proposed Karkit Hydro Electric Project envisages construction of a dam 1 km downstream of the confluence of Dras and Shingo Rivers with an underground powerhouse near Harka Bahadur Memorial upstream of the confluence of Shingo and Suru Rivers. The length of the HRT is 11 km and the estimated power potential is 180 MW with 124 m head and 126 cumecs designed discharge. The project components of this project are located within Ladakh Granitoid Complex comprising heterogeneous rock association of granite, gabbro, basic dykes, meta-volcanics and meta-sediments. During the course of the Pre-feasibility geotechnical investigation, one new project site was identified and height of the dam in one project was suggested for enhancement based on the geotechnical considerations. This led to revision of aggregate power potential of these projects from 172 MW to 305 MW, i.e. an addition of considerable 133 MW power potential
