Location: TEHRI, UTTARANCHAL

Capacity: [MW 4 X 100]

The project envisages installation of 4 Units of 100 MW each. It is a run-of-the-river project, and would utilize the downstream waters of Tehri Stage-I (4×250 MW). It is an integral part of Tehri Power Complex comprising of Tehri dam & HPP (1000 MW), Tehri Pumped Storage Plant (1000 MW), and Koteshwar H. E. P (400 MW) to develop hydro-electric potential of the river Bhagirathi. The project-site is located 22 Km dowmstream of the Tehri Power Station. Main structural components of the project include construction of 97.5 M high concrete gravity dam, a surface Powerhouse, and 582 M diversion tunnel. While sanctioning the Tehri Dam and HEP Stage-I in 1994, an amount of Rs.34.36 crore was sanctioned for committed works of Koteshwar project. The project is being executed as a joint venture project of Government of India and Government of U.P. A total of Rs.325.62 crore is to be the equity (equity of Govt. of India and GOUP in the ratio of 3:1), an amount of Rs.717.2 crores loan from PFC and Rs.259.69 crore as ECB.

Present Status:

The river Bhagirathi was diverted on 28th Dec.03. Open excavation relating to the dam, stilling basin, power intake, and the powerhouse has since been completed, and concreting is in progress. The work of excavation in switchyard & TRC area is in progress. Underground excavation for penstocks & drainage galleries is in advance stage. Also, concreting in dam pit is currently in progress. Contract for design, manufacturing, and supply of electro-mechanical equipment main generating unit including auxiliaries and EOT cranes has been awarded to M/s BHEL. Supplies against E&M equipment from M/s BHEL are being received progressively at the site. 59.14% of total supplies have been received till June 09.

The project is currently delayed on account of slope failure on the right bank in Nov 05, and poor performance on the part of sub-contractor. Excavation for fright shaft on left bank and in the swith yard area have been completed. The likely date for completion of the project is Dec,2010.
