Koteshwar Dam

The Koteshwar Dam is a gravity dam on the Bhagirathi River, located 22 km (14 mi) downstream of the Tehri Dam in Tehri District, Uttarakhand, India. The dam is part of the Tehri Hydropower Complex and serves to regulate the Tehri Dam's tailrace for irrigation and create the lower reservoir of the Tehri Pumped Storage Power Station. In addition, the dam has a 400 MW (4x100 MW) run-of-the-river power station.[3] The project was approved in 2000 and its first generator was commissioned on 27 March 2011, the second on 30 March 2011. The construction site had been inundated in September 2010 by floods. The diversion tunnel was later blocked heaving/collapse of the hill in December 2010. The spillway was commissioned in Jan,2011.[4] The last two generators were made operational in March 2012.[5]

The dam is 97.5 m (320 ft) tall and 300 m (984 ft) long. It has a structural volume of 560,000 m3 (732,452 cu yd) and its crest lies at an elevation of 618.5 m (2,029 ft) above sea level. The dam's spillway consists of four 18 m (59 ft) wide and 16 m (52 ft) tall radial gates. When the reservoir is at flood level, the spillway has a discharge capacity of 13,240 m3/s (467,566 cu ft/s). Receiving water from Tehri Dam and collecting it from an overall 7,691 km2 (2,970 sq mi) catchment area, the dam creates a reservoir with a 88,900,000 m3 (72,072 acre⋅ft) capacity, of which 35,000,000 m3 (28,375 acre⋅ft) is active (or "useful"). The reservoir's surface area is 29 km2 (11 sq mi) and at full pool, it lies at an elevation of 612.5 m (2,010 ft). The dam's power station is a run-of-the-river type and uses the active storage in the reservoir which can draw the lake down 30 m (98 ft) from full pool. The power house is located on the right bank of the river below the dam and contains 4 x 100 MW Francis turbine-generators. The height of the dam allows for a maximum 75 m (246 ft) of hydraulic head.[1][2]

Bhagirathi River

The Bhāgīrathī (Pron:/ˌbʌgɪˈɹɑːθɪ/) is a turbulent Himalayan river in the Indian state of Uttarakhand, and one of the two headstreams (or source) of the Ganges, the major river of Northern India and considered holy in Hinduism. In Hindu faith and culture, the Bhagirathi is considered the source stream of the Ganges. However, in hydrology, the other headstream, Alaknanda, is considered the source stream on account of its great length and discharge.

In addition, more than 10 projects are under various stages of construction. Tehri PSP (1000 MW) and Vishnugad-Pipalkoti HEP (444 MW) are in advance stage and are expected to commission by 2018. THDCIL has also ventured in to thermal power generation with its 1320 MW Thermal Power project coming up near Dussehera village which is near to Khurja, District Bulandshahr, Uttar Pradesh.

Tehri Dam

The Tehri Dam is the highest dam in India and one of the highest in the world. 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.
