It is a multi-purpose rock and earth - fill embankment dam on the Bhagirathi River near Tehri in Uttarakhand, India . It is the primary dam of the THDC India Ltd. and the Tehri hydroelectric complex . Phase 1 was completed in 2006, the Tehri Dam withholds a reservoir for irrigation, municipal water supply and the generation of 1,000 megawatts (1,300,000 hp) of hydroelectricity . The dam's 1,000 MW variable - speed pumped - storage scheme is currently under construction with expected commissioning in May 2018 . </P> <P> A preliminary investigation for the Tehri Dam Project was completed in 1961 and its design was completed in 1972 with a 600 MW capacity power plant based on the study . Construction began in 1978 after feasibility studies but was delayed due to financial, environmental and social impacts . In 1986, technical and financial assistance was provided by the USSR but this was interrupted years later with political instability . India was forced to take control of the project and at the first it was placed under the direction of the Irrigation Department of Uttar Pradesh . However, in 1988 the Tehri Hydro Development Corporation was formed to manage the dam and 75% of the funding would be provided 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 . Construction of the Tehri Dam was complete in 2006 while the second part of the project, the Koteshwar Dam was completed in 2012 . </P>
