Ranganadi Dam

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.

Power generation

The dam is intended for hydroelectric purposes and is part of Stage I of the Ranganadi Hydro Electric Project and supports the Dikrong Power House. The tall dam diverts water south into a headrace tunnel which is then transferred into a penstock before reaching the three 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 rock-fill embankment dam with a storage capacity. This dam will support an additional power station.
