Tehri Dam & HPP (1000 MW) comprises a 260.5 M high Earth & Rockfill dam which is one of the highest dams of its type in the world, a Spillway System designed for PMF of 15540 cumecs and a drop of 220m, having one Chute Spillway and four Shaft Spillways and an underground Power House housing four Turbine/ Generator sets of 250 MW each, designed to operate with a head variation of 90 m.


Project was commissioned in 2006-07 and all four machines of Tehri HPP are under commercial operation. Besides providing much needed power to the Northern Grid, the command area is availing irrigation benefits from the Project and drinking water is being supplied to Delhi and UP.




All four units (Unit-IV, Unit-III, Unit-II & Unit-I) were synchronized with the Northern Grid in July’ 06, Oct’06, Jan’07 & Mar’07 and are in commercial operation w.e.f. 22nd Sep’06, 9th Nov’06, 30th March’07 & 9th July’ 07 respectively.

* Generation during the month was less due to less inflow and less irrigation requirement.







Approved Completion cost of the project is ` 8392.45 Cr. including IDC plus contingent liabilities on account of arbitration award/ court cases etc, as per actual but not exceeding  ` 967.38 Cr.



The tariff for the period 2006-09 had been approved by Hon’ble Central Electricity Regulatory Commission (CERC) on 16.04.13. THDCIL had filed a review petition on 29.05.14. Hon’ble CERC  has revised upward the AFCs by `19.59 Cr.  for the period 2006-09 vide order dated 05.06.14. The tariff for the period 2009-14 has been issued by Hon’ble CERC on 27.01.15.  








Koteshwar Hydro-Electric Project (400 MW), located 22 km downstream of Tehri, is an integral part of Tehri Power Complex comprising of Tehri Dam & HPP (1000 MW), Tehri PSP (1000MW) and Koteshwar HEP (400MW) to develop Hydro-electric potential of river Bhagirathi. It will facilitate the functioning of Tehri Power Complex as a major peaking station in Northern grid as reservoir created by Koteshwar Dam having a live storage capacity of 35.0 MCM will function as lower (balancing) reservoir for Tehri PSP. This project is also regulating water releases from Tehri reservoir for irrigation purpose.


Govt. of India approved the implementation of Koteshwar Hydro Electric Project (4X100 MW) in April’2000; at a cost of ` 1301.56 Cr including IDC of ` 190.04 Cr at Oct.’99 price level. Standing Committee on Time & Cost overrun in its fourth meeting held on 18th July’ 12 decided that THDCIL will submit updated RCE incorporating anticipated Completion Cost. RCE has been vetted by CEA to  vide letter dated 09.10.13 which works to ` 2558.79 Cr including IDC & FC of ` 383.88 Cr at Mar’12 PL.

 General layout of the Project is enclosed as Exhibit-I.





All four units (Unit-I, Unit-II, Unit-III & Unit-IV) were synchronized with the Northern Grid in March’ 11, March’11, Jan’12 & Mar’12 respectively and are in commercial operation w.e.f. 1st Apr’11, 26th Oct’11, 13th Feb’12 & 1st Apr’ 12 respectively.

·         At the D/s slopes of left bank above outlet of diversion tunnel, where  number of wet patches and flow of seepage was observed, drilling of drainage holes on all wet patches is in progress as advised by TAC. 256 nos. of drainage holes have been drilled so far against the total quantity of 262 holes. The average seepage from drilled holes corresponding to reservoir level of +609.50 is about 4.0 lit/sec.


·                  For the execution of Balance Civil work of Koteshwar HEP amounting to `141.80Cr, agreement has been signed with M/s Patel Engineering Limited on 12.11.14. Mobilization of machinery, plant and manpower is in progress. Grouting of sluiced aggregate in diversion tunnel from EL 620.00m platform and construction of Portal for Access Adit from EL 635.0 M has been taken up and is in progress. All the works under the contract like plugging of Diversion Tunnel, Left Bank stabilization, Overt lining of Main Access Tunnel, Finishing work of Power House etc. likely to be completed by July’16. 


·                  Execution of some other essential works such as concrete lining on road berm and platform at EL 590, treatment of Sain Nalah spillage area has been taken up under a separate contract. About 70 % concrete lining at EL 590.00 M platform has been completed. Preparatory works are in progress for taking up the works of other areas.

Hon’ble CERC has considered 85% of Capital Cost as on COD of the station while determining AFC for the period 2011-14. A Review Petition has been filed before Hon’ble CERC on 12.07.14. The hearing before Hon’ble CERC is expected to be held shortly.




Tehri PSP comprising of four reversible pump turbine units of 250 MW each involves construction of an Underground Machine Hall on the left bank of river Bhagirathi.  The main feature of the Project is the large variation of about 90 m between the maximum and minimum head, under which the reversible units shall operate. The operation of Tehri PSP is based on the concept of recycling of water discharged between upper reservoir and lower reservoir. The Tehri Dam reservoir shall function as the upper reservoir and Koteshwar reservoir as the lower balancing reservoir.


On completion, additional generating capacity of 1000 MW, peaking power will be added to the Northern Region (annual generation of 1268 million units). For pumping operation of reversible units during off-peak hours, the energy requirement will be of the order of      1712 MU limited to maximum of 1000 MW during off-peak hours. With the construction of Tehri PSP, Tehri Hydro Power Complex shall function as a major peaking station having an installed capacity of 2400 MW.

     The Power House has been planned in Hat village (out of Dolomite zone) between Ch. 300 - 446 M.  Accordingly, cross drift (total 75 M) at new location at Ch. 410 M on R/S has been excavated. As part of intensive investigations, the drift has further been extended upto 90 M at Ch. 500 M. Cross cuts could not be completed due to hurdles created by Harsari villagers. To resolve the issue, DM (Chamoli) convened the meeting of Harsari villagers and issued instructions to plan drift / adit from outside the boundary of Harsari village.  

·         Accordingly and also on recommendations of Project Review Panel ( PRP) to shift the Power House to PH #4 location, a new drift  avoiding Harsari village has been taken up and has been excavated up to a length of  372 RM out of 415 RM.


Rehabilitation & Resettlement :


THDC India Ltd has formulated a Rehabilitation & Resettlement policy (R&R Policy) for the Vishnugad Pipalkoti Hydro Electric Project. The Policy is based on the National Rehabilitation & Resettlement Policy 2007 (NRRP-2007) incorporating the better features considering the World Bank Guidelines on Involuntary Settlement and needs and expectations of the stakeholders. The Policy addresses the R&R issues through proactive approach and appropriate Planning on Land Acquisition. Besides disbursement of compensation by Special Land Acquisition Officer (SLAO), the Policy envisages provisions of grants and other benefits considering the categories and the Entitlements.


For effective implementation of R&R policy, Rehabilitation Action Plan (RAP) has been formulated so that after reasonable transition period, the affected families improve, at least regain their previous standard of living, earning capacity and production levels. For implementation of R&R activities, a reputed local NGO Shri Bhuvneshwari Mahila Ashram (SBMA) has been engaged.
