The **Ranganadi Dam** is a concrete-gravity [diversion dam](/source/Diversion_dam) on the [Ranganadi River](/source/Ranganadi_River) (also known as Panyor River) in [Arunachal Pradesh](/source/Arunachal_Pradesh), [India](/source/India) which serves a [run-of-the-river](/source/Run-of-the-river) scheme.

## Power generation

The dam is intended for [hydroelectric](/source/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](/source/Penstock) before reaching the three 135 megawatts (181,000 hp) 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 134 m (440 ft) rock-fill embankment dam with a 523,000,000 m3 (1.85×1010 ft3) storage capacity. This dam will support an additional 180 megawatts (240,000 hp) [power station](/source/Power_station).[3]
