The Ranganadi Dam is a concrete-gravity diversion dam on the Ranganadi River in Arunachal Pradesh, India which serves a run-of-the-river scheme. The dam is intended for hydroelectric purposes and is part of Stage I of the Ranganadi Hydro Electric Project and supports the 405-megawatt (543,000 hp) Dikrong Power House. The 68 m (223 ft) tall dam diverts water south into a 10.1 km (6.3 mi) headrace tunnel which is then transferred into a 1,062 m (3,484 ft) penstock before reaching the three 135 megawatts (181,000 hp) turbines. Since commissioning, the power house has been generating much less than its capacity because of drought.
Stage II of the project is designed to provide water storage for Stage I and includes a 134 m (440 ft) rock-fill embankment dam with a 523,000,000 m3 (1.85×1010 cu ft) storage capacity. This dam will support an additional 180 megawatts (240,000 hp) power station.
