Project Detail:
Proposed structures to be constructed (Dulhasti Stage-II H.E. Project)
1 Nos. intake tunnel of size 7.7m dia circular shaped to be connected with already constructed intake tunnel of same size.
2 Nos. branch intake tunnels (before u/s transition of desilting chambers) of size 6.5m horse shoe shape bifurcated from intake tunnel.
2 Nos., 300m (L) x 15m (W) x 14.5m (H) underground desilting chambers.
2 Nos. branch HRT (after d/s transition of desilting chambers) of size 6.5m horse shoe shape combining to form main HRT.
1 No. 3575 m long HRT of size 8.5m dia horse shoe shaped in left bank with revised alignment.
1 No, 18.25m finished dia, circular shaped, restricted orifice Surge Shaft.
1 no., 7 m dia circular shape steel lined pressure tunnels/ shafts and 2 nos., 5m dia circular shape steel lined penstocks.
The present location of Power house and associated caverns have been shifted approximately 100m upstream. The proposed powerhouse cavern of size 100 m (L) x 23.5 m (W) x 52 m (H) shall house 2 units of 130 MW each having total installed capacity of 260 MW and annual Energy generation 90% (Dependable year) are 1092.82 MU.
Transformer cavern located d/s of power house cavern which will also house the Draft Tube gates.
1 no. 250m long (approx.) TRT of size 8.5m dia horse shoe shape.
To facilitate the construction and operation of the project components, suitable adits and Access tunnels have also been proposed.
The project is proposed to be commissioned in 60 months. The cost of the project is Rs. 1336.71 Cr. (Nov. 2020 PL).
