The Tehri Hydro Development Corporation (THDC) has commissioned the first 100 MW unit of the 400 MW Koteshwar Hydro Power project synchronising it with the Northern Grid.
The THDC has been able to achieve this feet despite all odds it faced as the project power house had got submerged in September 2010 due to floods. However, the Corporation overcame the crisis and was able to commission the first unit so fast.
An official statement issued here said the mechanical spinning of unit-1 got accomplished in January this year. Then subsequently the testing and commissioning works machine of unit-I was synchronised with the Northern grid.
Koteshwar Hydro-Electric Project is located 22 Km downstream of Tehri Dam on river Bhagirathi. Koteshwar Project is one of the constituents of Tehri. Other constituents of Tehri Power Complex (2400 MW) are Tehri Dam (1000 MW) and PSP (1000 MW).
Tehri is already in operation and Tehri PSP is under implementation. It will facilitate the functioning of Tehri Power complex as a major peaking station in Northern Grid. It is run-off the river scheme and will generate 1234 MU of energy annually. The reservoir created by Koteshwar Dam has live storage capacity of 35.0 MCM and will also function as lower (balancing) reservoir of Tehri PSP.
This project will also regulate water releases from Tehri Reservoir for irrigation purposes. The other three units will also be completed within the 11th plan. The Koteshwar dam is being built with a revised cost estimate of Rs. 2,466.9 crore.
