India ranks third in the world after China and the USA in terms of the number of dams. The country has about 4710 completed large dams. With the ever-increasing population and the consequent increased demand for water for various uses, it has become necessary not only to construct new dams but also to rehabilitate and maintain existing ones. The dams provide storages to tide over the temporal and spatial variation in rainfall for meeting the year-round requirements of drinking water supply, irrigation, hydropower, and industries in the country which lead to the development of the national economy. Biggest Dams in India have helped immensely in attaining self-sufficiency in food grain production besides flood control and drought mitigation.
At a time when the hydropower sector has taken a beating in India, power major NTPC is planning to set up the country’s biggest hydel project in Arunachal Pradesh. The hydropower project at Siang will alone generate between 10,000 to 12,000 MW when completed, making it the largest hydroelectric dam in South Asia. And 27,000 MW when collaborated with other power companies.
Below are the 10 Largest Hydroelectric Dams in India in terms of Power Generation.
1.) The Tehri Dam – is the highest dam in India and the tenth tallest dam in the world. It is a multi-purpose rock and earth-fill embankment dam on the Bhagirathi River near Tehri in Uttarakhand, India. The dam is a 260.5 meters (855 ft) high rock and earth-fill embankment dam. Its length is 575 meters. Tehri Hydro Power Complex (2400 MW), comprises the following components:
- Tehri Dam & Hydro Power Plant (1000 MW)
- Koteshwar Hydro Electric Project (400 MW)
- Tehri Pumped Storage Plant (PSP) (1000 MW) (Total capacity 2400 MW)
2.) The Koyna Hydroelectric Dam – is the second largest hydroelectric power plant of India. The total Installed capacity of the project is 1,960 MW. The project consists of 4 stages of power generation. All the generators are located in the underground Powerhouses excavated deep inside the surrounding mountains of the Western Ghats. A dam foot powerhouse also contributes to the electricity generation.
1st stage 4 x 70 MW = 280 MW
2nd stage 4 x 80 MW = 320 MW
Dam foot 2 x 20 MW = 40 MW
3rd stage 4 x 80 MW = 320 MW
4th stage 4 x 250 MW = 1,000 MW
Total capacity 1,960 MW
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 is the 3rd largest capacity hydroelectric project in the country with 1,670 MW generation of electricity.

7.) The Karcham Wangtoo Dam – is a 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 get its name from their. it was constructed by Jaypee Group who later sold it out to JSW Group. The main spillway is along the crest of the dam and is controlled by six radial gates.
Turbines 4 x 250 MW Francis-type
Total capacity 1,000 MW
8.) The Indirasagar Dam – is a multipurpose project of Madhya Pradesh on the Narmada River at Narmadanagar in the Khandwa district of Madhya Pradesh in India. The reservoir of 12,200,000,000 m3 was created. It withholds the largest reservoir in India, in terms of storage of water. Indira Sagar Project is a multipurpose Project with an installed capacity of 1,000 MW.

10.) The Idukki Dam – located in Kerala, India, is a 168.91 m (554 ft) tall arch dam. The dam stands with a beautiful view between the two mountains – Kuravanmala and Kurathimala. It was constructed and is owned by the Kerala State Electricity Board. It supports a 780 MW hydroelectric power station in Moolamattom.
Turbines 6 x 130 MW Pelton-type

Great amount of information! very valuable…
nice work… well done!
Normally I don’t read write-up in blogs, however i would like to express that this particular write-up incredibly required me to see and do so! Ones creating taste has been shocked me personally. Thanks a lot, good document.
This site give more information about dams in India
thanks for the information
It helped a lot thanks
yes it is
I think it will be very helpfull and I got lot of information about Hydel plants in India
this is all i wanted
really good piece of work…
There are certain range in himalayas where there is perpetual high wind. You can plant
thousands of wind mills and produce electricity. The engineering work does not take long like a construction of a dam. Develop a town around for retd personnel. Like china is going to build shangrilla in tibet and open it to the world. And they will earn $. You will thus develop the entire himalayan region. Dont waste time to construct roads. Use
Good Information.. But i wonder why we are far behind other countries with dams producing electricity with more than 5k – 6k mw. Despite so much scarcity of energy and constant power cuts. I think its high time now and its better we now start understand the actual caliber of the hydro electric power plant than those of any other( majorly thermal) and take onus to build and satisfy India’s high energy requirements.
Excellent informaton n images r too good……….. thanks.
Tehri Garhwal dam has established its name among the ten largest dams of India. Apart from this reputation it is drawing hordes of tourists to its location at the foothills. You can watch this dam from the heights of New Tehri. Thanks for sharing this valuable information
it is very useful
This is very essential portion for the student
It really help me. ……..
Iam havin geo exam tomm. thanx 4 the info…..
actually this is wht i was lukin for
after going through tha 10 biggest hydel power plants in the world i am shocked that india appears no where .Instead of thermal and gas based power plants Modi govt should try for more hydal plants which will be beneficial both for environment and irrigation .
good short information . for further details one can refer CBIP publiction ” Hydro power projects in India”
We know that india is a country of river and valleys half part is arounded by ocean so we have lots of apportunity to generate the hydal plant which is more benefit for public requirement.
So central goverment should allow to make evergreen enviroment.
maybe or new five hydraulic power dam
That was a very valuable information. Thank you very much
it was very informative.
Thank u so much.
Well, I commented that information was incomplete as Sharavati valley project produces 1400 MW (approx) which was taken down saying I am confusing multiple projects. Even then, they agreed that Sharavati power plant produces 1035 MW, which makes it no. 7. In reality, This power plant is series of plants (tail races and runoffs) just like Narmada Valley project with total capacity of 1400 (approx) MW. More details can be found at KPTCL website (operator). Can’t post link here.
I am thankful to you.for this important information.
Thank you so much
It is very useful information.
Thank you.It was really useful.
It’s a great information regarding hydel projects.
Thank you very much sir!
Lot of thank
Once the proposed dams in Lower Subansiri in Assam and other dams in Arunachal Pradesh are built all these ten top dams will go into oblivion.
Very informative and helpful for the students who are preparing for competitive examination. Good work Thanks a lot
It’s very important and valuable information about the major power projects in India to the young generation .. nice photographs with it of information. thanks
Very good content I am preparing for a national quiz in central water commission
It is quite informative and nice
Hi you people are are ignorent about our country’s installed capacity of hydroelectric power stations. There are 2 nos of major power stations in the state of Karnataka namely Sharavati valley and Kali river projects each of having installed 1000Mw and more. Please contact KEB and get vital information.
Very educative things,to know about India’s hydro power project,
running from couple of yrs,in which river,state and its location,
thanx a lot giving details about hydro power.
Great! Thank you for sharing valuable information about India’s top 10 biggest dam. Really i don’t know about that it’s a helpful for me
