Ranganadi Dam

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.

Power generation
The dam is intended for hydroelectric purposes and is part of Stage I of the Ranganadi Hydro Electric Project and supports the 405 MW Dikrong Power House. The 68 m tall dam diverts water south into a 10.1 km headrace tunnel which is then transferred into a 1062 m penstock before reaching the three 135 MW 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 rock-fill embankment dam with a 523000000 m3 storage capacity. This dam will support an additional 180 MW power station.
