The Tehri Dam is a 260 meter (855 feet) high rock and earth-fill embankment dam on the Bhagirathi River near Tehri in Uttarakhand, India. It is the primary dam of theTehri Hydro Development Corporation Ltd. and the Tehri hydroelectric complex. Completed in 2006, the Tehri Dam withholds a reservoir of 2.6 billion cubic meters for irrigation, municipal water supply and the generation of 1,000 MW of hydroelectricity along with an additional 1,000 MW of pumped storage hydroelectricity.
In 1988, the Tehri Hydro Development Corporation was formed to manage the dam and 75% of the funding would be provide by the federal government, 25% by the state. Uttar Pradesh would finance the entire irrigation portion of the project. In 1990, the project was reconsidered and the design changed to its current multi-purpose, including a 2400 MW hydro-electric power production capacity. Construction on the Tehri Dam was complete in 2006 while the second part of the project, the Koteshwar Dam, remains ongoing.
The 1000 MW Tehri Dam is part of the Tehri Hydropower Complex which also includes the 400 MW Koteshwar Dam downstream and the 1000 MW Tehri Pumped Storage Hydroelectric Power Plant which is set for completion in 2013. The Tehri dam along with the downstream Koteshwar Dam and the Tehri pumped storage hydroelectricity power plant will afford a power generation capacity of 2400 MW, provision of irrigation to an area of 270,000 hectares, irrigation stabilization to an area of 600,000 hectares, and a supply of 270 million gallons of drinking water per day to the industrialized areas of Delhi, Uttar Pradesh and Uttarakhand.
