Gyspa Dam Project

The Project envisages construction of a ±200 m high storage dam on Bhaga River upstream of Gyspa village in Keylong Tehsil of Lahaul & Spiti District of Himachal Pradesh. The water so stored shall be fed into 5.70m dia, ±14.964Km long HRT, a surge shaft ±20m diameter & ±200m deep, a pressure shaft 4.50m dia, ±520m long, to feed four Vertical shaft Francis turbines each of 75 MW capacity. An underground Power House is proposed at an EL±3025m about 300m u/s of Stingri GREF House, on the right bank of river Bhaga. The scheme shall utilize a gross head of 430.33 m for generating 300 MW of power with annual generation of ±894.86 MU in 90% dependable year. The storage dam will impound 0.65 MAf of water. Gyspa Dam Project has been declared as National Importance Project. CWC, MoWR released IWRD fund amounting to Rs. 5.00 Cr. to HPPCL for investigation & preparation of DPR.
