Description: Part of the Tehri Project Complex. This complex consists of 1,000-mw Tehri, already operating, and 400-mw Koteshwar, under construction. This complex features Tehri Dam, an earth and rock fill dam impounding the upper reservoir, and Koteshwar Dam, a concrete gravity dam impounding the lower reservoir. Tehri Dam is 260.5 meters high, with live storage of 2,615 million cubic meters. Koteshwar Dam is 97.5 meters high, with live storage of 35 million cubic meters.
Tehri Pumped-Storage will feature four 250-mw motor-generator units and variable speed pump-turbines. Associated structures include headrace tunnels, upstream and downstream surge shafts, penstocks, butterfly valve chamber, machine hall, tailrace tunnels, and outlet structures. The intakes and other associated structures – such as maintenance gate shafts, cable tunnel, and switchyard – were completed during construction of the Tehri project. Most of the construction adits for the pumped-storage project had been completed, which shortens the development timeline.
