The Karcham Wangtoo Hydroelectric Plant is a 1000MW run-of-the-river hydroelectric power station on the Sutlej River in Kinnaur district of Himachal Pradesh, India. The dam and power station are located between the villages of Karcham and Wangtoo where the plant also gains its name. Jaypee Karcham Hydro Corporation Limited of Jaypee Group signed a memorandum of understanding to develop the dam in 1993 and after years of delays, construction on the power station began on 18 November 2005. The first generator was commissioned in May 2011, the second in June and the final two in September. The 98 m (322 ft) tall dam at Karcham diverts a substantial portion of the Sutlej into a 10.48 m (34.4 ft) diameter and 17.2 km (10.7 mi) long headrace tunnel to the underground power station downstream at Wangtoo. At the station, the water powers four 250 MW Francis turbine-generators before it is sent back into the Sutlej via a 1.2 km (0.75 mi) long tailrace tunnel. The difference in elevation between the dam and the power station affords a gross hydraulic head of 298 m (978 ft). Water not diverted by the dam is sent over the spillway and down the normal course of the river. The main spillway is along the crest of the dam and is controlled by six radial gates. Just upstream of the dam is the 300 MW Baspa II Hydroelectric Plant and downstream of the Karcham Wangtoo is the 1,500 MW Nathpa Jhakri Dam. The Nathpa Jhakri Dam is a concrete gravity dam on the Satluj River in Himachal Pradesh, India. The primary purpose of the dam is hydroelectric power production and it supplies a 1,500 MW underground power station with water. Before reaching the power station, water is diverted through a 27.4 km (17 mi) headrace tunnel. Construction on the project began in 1993 and it was complete in 2004. The Sutlej River is the longest of the five rivers that flow through the historic crossroads region of Punjab in northern India and Pakistan. It is located north of the Vindhya Range, south of the Hindu Kush segment of the Himalayas, and east of the Central Sulaiman Range in Pakistan. The Sutlej is sometimes known as the Red River. It is the easternmost tributary of the Indus River. Its source is Lake Rakshastal in Tibet. From there, under the Tibetan name Langqên Zangbo (Elephant River), it flows at first west-northwest for about 260 kilometres (160 mi) to the Shipki La pass, entering India in Himachal Pradesh state. It then turns slightly, heading west-southwest for about 360 kilometres (220 mi) to meet the Beas River near Makhu, Firozpur district, Punjab state. Continuing west-southwest, the Sutlej enters Pakistan about 15 kilometres (9.3 mi) east of Bhedian Kalan, Kasur District, Punjab province, continuing southwest to water the ancient and historical former Bahawalpur princely state. About 17 kilometres (11 mi) north of Uch Sharif, the Sutlej unites with the Chenab River, forming the Punjab River, which finally flows into the Indus river about 100 kilometres (62 mi) west of the city of Bahawalpur. The area to the southeast on the Pakistani side of the Indian border is called the Cholistan Desert and, on the Indian side, the Thar Desert. The Indus then flows through a gorge near Sukkur and the fertile plains region of Sindh, forming a large delta region between the border of Gujarat, India and Pakistan, finally terminating in the Arabian Sea near the port city of Karachi, Pakistan. The waters of the Sutlej are allocated to India under the Indus Waters Treaty between India and Pakistan, and are mostly diverted to irrigation canals in India. There are several major hydroelectric projects on the Sutlej, including the 1,000 MW Bhakra Dam, the 1,000 MW Karcham Wangtoo Hydroelectric Plant, and the 1,530 MW Nathpa Jhakri Dam. There has been a proposal to build a 214-kilometre (133 mi) long heavy freight canal, to be known as the Sutlej-Yamuna Link (SYL), in India to connect the Sutlej and Yamuna rivers. The project is intended to connect the Ganges, which flows to the east coast of the subcontinent, with points west, via Pakistan. When completed, the SYL would enable inland shipping from India's east coast to its west coast (on the Arabian sea) without having to round the southern tip of India by sea, vastly shortening shipping distances, alleviating pressures on seaports, avoiding sea hazards, creating business opportunities along the route, raising real estate values, raising tax revenue, and establishing important commercial links and providing jobs for north-central India's large population. However, the proposal has met with obstacles and has been referred to the Supreme Court of India. more from megastructure Abu Dhabi Central Market - Extreme Engineering - Megastructures Documentary AL-Hamra Mall kuwait Big Bigger Biggest Airport -Heathrow Airport BIG BIGGER BIGGEST bridge BIG BIGGER BIGGEST Metro Build It Bigger Azerbaijan's Amazing Transformation
