10 Largest Power Generating Hydroelectric Dams in India

The 10 Largest Power Generating Hydroelectric Dams in India.

India ranks third in the world after the China and the USA in terms in the number of dams. The country has about 4710 concluded large dams. With the ever-increasing population and the resulting in increased demand for the water for various uses, it has become necessary not only to construct new dams but also to re-establish and maintain the existing ones. The dams provide storage to tide over the temporal and the spatial variation in rainfall for meeting the year-round requirements of the drinking water supply, irrigation, hydro power, and the industries in the country which lead to the development of the national economy.

Below are the 10 Largest Hydroelectric Dams in India in the terms of Generating the power.

1.) The Tehri Dam – is considered as the highest dam of India and the tenth tallest dam of the world.  It is a multi-purpose rock and the earth-fill embankment dam on the Bhagirathi River near Tehri in Uttarakhand, India.  The dam is almost 260.5 meters (855 ft) high rock and the earth-fill embankment dam is about 575 meters. Tehri Hydro Power Complex (2400 MW). 

2.) The Koyna Hydroelectric Dam – is considered as the second largest hydroelectric power plant in India. The total Installed capacity of the project is about 1,960 MW. The project consists of 4 stages of the power generation. All the generators are located in the underground Powerhouses burrow  it deep inside the surrounding mountains of the Western Ghats. A dam foot of the powerhouse also contributes to the electricity generation.

3.) The Srisailam Dam – is a dam constructed across the Krishna River at Srisailam in the Kurnool district in the state of Andhra Pradesh in India and it is considered as the 3rd largest capacity hydroelectric project in the country with about 1,670 MW generation of the electricity.

4.) The Nathpa Jhakri Dam – is a existing gravity dam on the Satluj River in Himachal Pradesh, India. The primary purpose of the dam is the hydroelectric power production and it supplies a 1,500 MW underground power station with the water.

5.) The Sardar Sarovar Dam – is a existing gravity dam on the Narmada River near the Navagam, Gujarat in India. It is the largest dam and is the part of the Narmada Valley Project, a large hydraulic engineering project is involving in the construction of a series of the large irrigation and the hydroelectric multi-purpose dams on the Narmada River.

6.) The Bhakra-Nangal Dam – is a existing gravity dam across the Sutlej River, and is in Bilaspur, Himachal Pradesh  in India. Its reservoir, known as the “Gobind Sagar”, stores up to 9.34 billion of cubic meters of the water, making it the second largest reservoir in India, enough to drain the whole Chandigarh, parts of Haryana, Punjab and Delhi.

7.) The Karcham Wangtoo Dam – is about 1,000 megawatts power station on the Sutlej River in Himachal Pradesh at Kinnaur district of India. The dam is located between the villages of Karcham and Wangtoo and has got its name from their. it was constructed by the Jaypee Group who later sold it out to JSW Group. The main spillway is along the crest of the dam and is controlled by the six radial gates.

8.) The Indirasagar Dam – is a multipurpose project of Madhya Pradesh on the Narmada River at the Narmadanagar in the Khandwa district of Madhya Pradesh in India. The reservoir of 12,200,000,000 m 3 was created. It withholds the largest reservoir in India, in terms of the storage of the water. Indira Sagar Project is a multipurpose Project with an installation capacity of 1,000 MW.

9.) Nagarjuna Sagar Dam – is a brickwork dam on the Krishna River at Nagarjuna Sagar in the border of the Guntur and the Nalgonda districts of the Andhra Pradesh State, in India. The duration of constructing the dam was between the year of 1955 and 1967.

10.) The Idukki Dam – which is located in Kerala, in India, is about 168.91 m (554 ft) tall bridge dam. The dam stands between the beautiful view of the two mountains –known as Kuravanmala and Kurathimala. It was build and is owned by the Kerala State Electricity Board. It supports upto 780 MW of the hydroelectric power station to Moolamattom
