Hydroelectric energy is one of the most preferred forms of energy in the world today. It is a kind of renewable energy and do not require the aid of burning fossil fuels for the generation of electricity/energy. When a certain volume of water reaches the top of a dam or flows downwards with great speed, it consists of potential energy. This potential energy can be converted to form hydroelectric energy by converting the potential energy into kinetic energy and allowing the water to run in the blades of the turbine which are put in place. The electricity produced is then distributed to the customers of the power plant.
Hydroelectric Power Plants in India: Background
Hydroelectric power plants in India have gained a lot of momentum in recent times. India has realized that there is a huge potential for the generation of electricity from hydrological power plants and thus, many projects have been put into action to maximize this renewable form of energy generation. From the end of the 19th century, India has witnessed the start of hydroelectric power plant projects in different parts of the country. It is not possible to build such projects in every area and not all cities or villages can be introduced to electricity generated from this source due to multiple economic and geographical limitations. However, the number of power plants has increased over the years as there has been more emphasis on renewable energy sources in the last 20 years or so.

Location of the Power Plants in India
All the hydroelectric power plants in India are built on large river bodies where there is an abundant source of water coming from the mountains. The power plants are all built on a dam which lies over the river bodies.
Conclusion
Hydroelectric power plants in India are projects made to generate electricity from the potential energy of the water when water is stored in large volumes in a relatively high-altitude area and then let to fall in a low surface from a great height and convert the potential energy into kinetic energy with the help of turbines. These projects are becoming more and more popular in India as the urge for a sustainable future requires such projects to be in practice as much as possible. India is looking to increase the number of hydel power generating plants all over the countries and develop the level of power generation and widen its distribution across the different cities and villages of the country.
