Renewable Energy Sources in India

India is the seventh-largest producer of hydroelectric energy in the world, with a total installed capacity of 47,057 MW.

India, which has a population of over 1.4 billion, is the third-largest consumer and producer of electricity in the world, with 403.7 GW of installed capacity as of June 2022. This electricity is primarily produced by thermal power plants using fossil fuels.

However, it has committed to reducing climate change by promoting the development of more renewable energy sources, such as wind and solar power. By constructing nuclear power plants, the nation is also concentrating on developing nuclear energy.

ower development in India began at the end of the 19th century when electricity was first made available in Darjeeling in 1897. A hydropower station in Sivasamundram, Karnataka, was then put into operation in 1902.

Given that energy is a crucial component of economic growth and enhances quality of life

The Unexploited Hydropower Potential of India

One of the most important renewable energy sources for producing electrical energy in India has been hydroelectric power projects. India has not fully exploited its hydropower potential, despite having the fifth-largest hydropower potential (1,48,700 MW) after China, Brazil, the US, and Canada.

India had 197 hydroelectric power plants that were all in operation as of March 2022, producing 46,850 MW. However, a quarter of this power is produced by the seven biggest hydroelectric power plants.

The seven largest hydroelectric power projects in India as of July 2022 are listed in the following sections.

What is the Largest Hydroelectric Power Plant in India Today

The Koyna Hydroelectric Project, located in the Satara district of Maharashtra, is the largest hydroelectric power plant in the country. The project is managed by the State Electricity Board. The Koyna Dam, one of the largest dams on the Koyna River, is part of the complex of four dams that make up the Konya Hydroelectric Project. It is located close to the village of Koynanagar. The largest hydroelectric power plant in India has a 1960 MW total capacity.

Each of the project's four stages has a subterranean power station constructed deep within the Western Ghats. With their extremely tall mountain ranges, the Western Ghats produce enormous hydraulic heads. This is a key distinction between the western and eastern ghats. The first stage of this massive hydroelectric power plant in India was put into operation in May 1962, and the final stage wasn't until 1981.

What is the Oldest Hydroelectric Power Plant in India

Sidrapong Hydroelectric Power Station, situated 12 kilometers from Darjeeling Town at the foothills of the Arya Tea Estate, is the country's first hydroelectric power station. On November 10th, 1897, the Sidrapong hydroelectric power station, also known as the Sidrapong hydel power station, was officially opened. The power station's initial output was 265 kW. The total capacity of this capacity was raised to 1000 kW in 1916.

The project's outdated equipment was replaced in 1931 with more effective triple-phase transmission. WBSEB, or the West Bengal State Electricity Board, took over the operation in 1978. The power station was severely impacted by the landslide after two years, but it was restored in 1997. The first hydroelectric power plant in India is now recognized by the national government as a cultural heritage.
