Salient features of the proposed TIUNI-PLASU HYDROELECTRIC PROJECT are as under:
|
| Gross catchment area |
3320 km2 |
| Maximum design flood for Hydraulic design |
7000 cumec |
| Maximum design flood for Structural design |
7810 cumec |
| Full Reservoir Level |
929.50 m |
| Crest level of Undersluice |
909.50 m |
| No. & width of Undersluice bay |
1 no. & 15 m. |
| Crest level of other bays |
911.00 m |
| No. & width of other bays |
7 nos. & 15 m each |
| Length of Barrage |
138.00 m |
| Type of Intake |
Side intake on left bank |
| Design discharge through intake |
181 cumec |
| Crest level of Intake |
917.50 m |
| Underground Desilting chamber |
360m x 20m x 21m, 2 no. |
| Intake Tunnel |
6.00 m diameter, 90.50 cumec, 2.035 km. long (2 nos.) |
| Head Race Tunnel |
7.60 m diameter, 145 cumec, 1.850 km. long |
| Surge Shaft |
35.0m dia & 28 m deep |
| Pressure Shaft/Penstock |
nos. each 4.0m dia & 110 m long |
| Type of Power house |
Surface power house on left bank of river Tons |
| Type of Turbine |
Vertical Francis |
| Maximum Gross Head |
67.10 m |
| Installed capacity |
3x24 MW |
| Annual units generated in 90% Dependable year |
293.90 MU |
| Annual units generated in 50% Dependable year |
445.57 MU |
| Total estimated cost of the project |
Rs. 979.00 crores |
| Construction Period |
4 years |
The scheme would generate 423.29 million kwh in 50% dependable year with 95%
plant availability factor. The cost of the project including escalation in cost
during construction period and interest on loan amount during construction (IDC)
is estimated at Rs. 82953 lakh. The sale price is estimated at Rs. 3.97 per
kwh in the first year and the levellised sale price is Rs. 3.55 per kwh.
The Tiuni Plasu Hydroelectric Project (72 MW) on river Tons in district Dehradun
is therefore a technically feasible, viable and eligible project for development to
meet the energy requirement of the State. The sale price of Rs. 3.55/- per
kWh may appear to be on higher side at the first sight. However, considering that energy is
becoming scarcer day-by-day, the cost of energy in the long run shall be economical.
Hence, construction of 72 MW Tiuni Plasu Hydroelectric Project is worth for consideration.
