As you know, Hydropower plants are which delivers electricity by generating power from Dams. The restricted water in the dam falls on the turbine to generate electricity.
In this context, This guide will give you the 10 Largest Hydropower plants in India, which will give you a broader view of various power plants in India with their power delivery capacity.
So, without further delays, let’s get started…
Here are the Top10 Hydropower Plants in India-
- Tehri Dam
- Koyna Dam
- Srisailam Dam
- Nathpa Jhakri Dam
- Sardar Sarovar Dam
- Bhakhra Nangal Dam
- Chamera Dam
- Sharavathi Dam
- Indira Sagar Dam
- Karcham Wangtoo Dam
Now, Let’s dwell inside these Dams, One by one-
Tehri Dam is India’s largest hydropower plant in India with a capacity of 2400MW located in Tehri, Uttarakhand on the Bhagirathi river. This dam is known as India’s tallest Dam run by THDC India Limited under the ownership of the National thermal power corporation of India.
Tehri Dam is an embankment 3 stage dam with a height of 260.5 Meters, Length 592 Meters, and top width of 25.5 Meters. Tehri Dam covers 42km2 of the area. Due to this splendour Dam, This area is also known as ”National Village” or ”Rastra ka Gaw”.
Tehri Dam is Asia’s tallest and the World’s fourth Tallest Dam in the Embankment Dam category with 260.5 Meters of Height.
Tehri Dam is World’s 8th tallest Dam as per overall ranking. The official name of Tehri Dam is Swami Ramtirtha Sagar.
In 1949, the Up government initiated the plan to build a Dam in Tehri and a survey was done till 1961. Professor James Brun designed the Tehri Dam in 1970.
Tehri Hydro Electric Project is divided into two phases –
- Tehri Dam & Hydropower Plant(1000MW)
- Tehri Pumped storage plant(1000MW)
And, the second phase is divided into a single sub-phase, namely-
- Koteshwar Dam(400MW)
Now, let’s talk about the Merits and Demerits of Tehri Dam-
Advantages of Tehri Dam-
- Power supply to a wide range of states including Jammu & Kashmir, Punjab, Uttar Pradesh, Haryana, Rajasthan, Delhi and Uttarakhand.
- Drinking water supply to states like Uttar Pradesh and Delhi.
- Irrigation water supply
- Reduces flood
- Fishing & Tourism
- Local Employment
Disadvantages of Tehri Dam-
- Displacements of locals
- A huge change in climate

These both dams are called Bhakhra Nangal Dam together.
Bhakhra dam is the third-largest reservoir in India with a spread area of 168.35km2 along with 226Meter height, making it one of the highest gravity dams in the world.
Benefits of Bhakra Nangal Dam-
- Increase in food grain yield
- Increase in cotton yield
- Supply of irrigation water
- tourism & Fishing
- Increase in Employment
