The Ranganadi Dam is a concrete-gravity diversion dam on the Ranganadi River (also known as Panyor 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 405MW Dikrong Power House. The 68m (223feet) tall dam diverts water south into a 10.1km (06.3miles) headrace tunnel which is then transferred into a 1062m (3,484feet) penstock before reaching the three turbines.[1] Since commissioning, the power house has been generating much less than its capacity because of drought.[2]
Stage II of the project is designed to provide water storage for Stage I and includes a 134m (440feet) rock-fill embankment dam with a 523000000m2 storage capacity. This dam will support an additional power station.[3]
