Project Detail:

The company has proposed Oju-II hydroelectric project with diversion structure at a location 1.5km downstream of Jakina Siko nallah with FRL at EL 1650m and tailwater level as +1300m.
As per the proposed layout various components of the project are as under:
1. 2 numbers of 10m diameter horseshoe shaped diversion tunnels each 800m and 925m long with upstream and downstream cofferdams.
2. 90m high concrete gravity dam from deepest foundation level with FRL at EL 1650m.
3. Water conductor system consisting of:
? 2 nos. intake structure
? 4 nos 300m (L) x 17m (W) x 23m (H) de-silting chamber.
? 10.25m diameter horseshoe shaped headrace tunnel 5.0km long.
? 20m diameter surge shaft having 85m height.
? One number 8m diameter, 308m height steel lined pressure shaft further dividing into 4 nos. penstocks to feed four units
? 10.25m dia horseshoe shaped tailrace tunnel 200m long meeting the river at a location where riverbed elevation is 1290 m
4. An underground powerhouse consisting of
? 124m (L) x 22m (W) x 48m (H) powerhouse cavern
? 96m (L) x 20m (W) x 25m (H) transformer-cum-draft tube gate cavern
? 96m (L) x 12m (W) x 16m (H) MIV cavern
