HISTORICAL BACKGROUND

The Tehri Dam & Hydro Electric Project had initially been accorded Investment Clearance by the Planning Commission in June, 1972 for implementation by the Government of U.P., with an installed generating capacity of 600 MW. The State Government commenced the construction of the Project in 1978. Subsequently, in 1983, the proposed Installed Capacity of the Project was increased by the State Government to 1000 MW.

In view of the shortage of funds for implementation of the Project in the State sector,  it was decided in Nov.,1986 to implement  the  Tehri project  as a Joint Venture of the Govt. of India and  Govt. of U.P. through financial and technical assistance from erstwhile USSR.

In  Nov.,1986,  an agreement on economic and  technical  co-operation  between the Govt. of India and Govt. of USSR  was signed, which interallia included execution of the 2400  MW Tehri Hydro  Power  Complex comprising 1000 MW Tehri Dam  &  Hydro Power Plant,  400 MW Koteshwar Dam  &  Hydro  Power Plant  and  1000  MW  Tehri  Pumped  Storage  Plant. This agreement envisaged financing in the  form of credit amounting to 1000 million Roubles from USSR.

The Government had also approved seeking the technical and financial assistance from the then USSR for implementing the Tehri Power Complex. However, with the disintegration of USSR, the financial assistance from USSR was not available.

ABOUT THE CORPORATION

THDC, a Joint Venture Corporation of the Govt. of India and Govt. of U.P., was incorporated as a Limited Company under the Companies Act,1956, in July’88, to develop, operate and maintain the Tehri Hydro Power Complex and other Hydro Projects. The works were handed over to THDC in June 1989.

The equity portion the Project is being shared by Govt. of India & Govt. of U.P in the ratio of 75:25.

The Corporation has an authorised share capital of Rs.4000 cr.

The Government approved the implementation of Tehri Dam and HPP Stage-I (1000 MW) in March,1994, alongwith the essential works of Pumped Storage Plant and committed works of Koteshwar HEP. Other components of the Tehri Power Complex, viz., Koteshwar Project, and the Pumped Storage Plant, were envisaged to be taken up at a later stage 

The Koteshwar HEP (400 MW) was approved for implementation by the Government in April’2000. Investment approval has been accorded by the Government in July’06 to the Tehri PSP(1000 MW), the first Pumped Storage Scheme in the Central sector which would utilize the Tehri & Koteshwar reservoirs as the requisite upstream & downstream reservoirs.

Govt. of India has accorded Investment Approval for execution of 444 MW Vishnugad Pipalkoti Hydro Electric Project (VPHEP) on River Alaknanda in    Aug’ 2008.

Govt. of Uttarakhand has also entrusted  Hydro Projects to THDC in Bhagirathi, Alaknanda and Sarda Valleys in Uttarakhand, totaling to 760 MW.

Govt. of Uttarakhand has accorded In-principle approval to allot Kishau Multi Purpose Project (600 MW) on river Tons, a tributary of Yamuna. Govt. of India has given approval for updation of DPR of the Project by THDC.

THDC has entered into an MOU with Nuclear Power Corporation of India Ltd. (NPCIL) to synergize strengths and competencies for development of Hydro Power Projects including Pumped Storage Schemes in the country. Govt. of Maharashtra has allotted 2 PSPs namely Malshej Ghat (600 MW) & Humbarli (400MW) to the Joint Venture of THDC and NPCIL for updation of DPR and subsequent implementation subject to commercial viability.

Under India-Bhutan Co-operation in hydro Sector development , MOP has allotted two Projects namely Sankosh Multi Purpose Project (4060 MW) and Bunakha HEP (180 MW) in Bhutan for updation of DPR, and subsequent implementation on Intergovernmental Authority Model / JV with Bhutanese PSUs. The work of updation of DPRs has been taken up.

THDC is also engaged in the engineering consultancy work for stabilization of Varunavat Parvat in Uttarkashi entrusted by Government of Uttarakhand. The work involves providing the complete engineering solution to the major hill stabilization problem and also supervising the execution of works at site.

The Corporation has commissioned Tehri Dam and HPP Stage-I (1000 MW) during Xth plan. The Tehri Power Station is now fully operational.
