Hydroelectric Power Plants in India
India is 5th globally for installed hydroelectric power capacity. As of 31 March 2020, India’s installed utility-scale hydroelectric capacity was 46,000 MW or 12.3% of its total utility power generation capacity. Additional smaller hydroelectric power units with a total capacity of 4,683 MW (1.3% of its total utility power generation capacity) have been installed.
The end of the 19th century saw the development of power in India. In 1897, electricity was commissioned in Darjeeling and in 1902, a Hydro Power station at Sivasamudram in Karnataka was commissioned.
- The Koyna Hydroelectric Project is the largest completed hydroelectric power plant in India. It has a power capacity of 1960 MW.
- The first hydroelectric power station was the Shivanasamudra hydroelectric power station.
- Tehri Hydro Electric Power plant is the highest hydroelectric power project in the country, also Tehri Dam is the tallest one in India. Now, NTPC has taken over the project (Since 2019).
- Srisailam Hydro Power Plant is the third largest working project in India.
- Nathpa Jhakri Hydroelectric Power Plant is the biggest underground hydroelectric power project in the country.
- Sardar Sarovar Dam is the world’s second-largest concrete dam.
Hydropower projects are classified as large and small hydro projects based on their sizes. Different countries have different size criteria to classify small hydropower project capacity ranging from 10MW to 50 MW.
In India, hydropower plants of 25MW or below capacity are classified as small hydro, which have further been classified into micro (100kW or below), mini (101kW-2MW), and small hydro (2-25MW) segments.
Hydro Power was being looked after by the Ministry of Power prior to 1989 mainly with the help of State Electricity Boards. In 1989, plant capacity up to 3MW and below was transferred to the Ministry of New and Renewable Energy (MNRE), and as such 63 MW aggregate installed capacity of 3MW and below hydro projects came within the jurisdiction of MNRE.
Many initiatives were taken by the Ministry since then for the promotion of small hydro which included implementation of a UNDP-GEF assisted Technical Assistance project entitled “Optimizing Development of Small Hydro Resources in Hilly Regions of India” and India-Renewable Resources Development Project with IDA credit line having interalia small hydro development component with a target of 100MW canal-based small hydro power projects through private sector participation.
Subsequently, plant capacity up to 25MW and below was entrusted with the MNRE in November 1999.
The estimated potential of 21135.37 MW from 7135 sites for power generation in the country from small/mini hydel projects is assessed by the Alternate Hydro Energy Centre (AHEC) of IIT Roorkee in its Small Hydro Database of July 2016.
The hilly States of India mainly Arunachal Pradesh, Himachal Pradesh, Jammu & Kashmir and Uttarakhand, and constitute around half of this potential. Other potential States are Maharashtra, Chhattisgarh, Karnataka, and Kerala.
