There are several ways of producing electricity, we use different types of power plants depending upon the availability of the source. For example, we have thermal power plants, we have tidal power plants, etc. One of the most widely utilized power plants is the hydroelectric power plants.
Hydroelectric power plants are designed for producing electricity with the help of the flow of water also known as hydro energy. We know that 75% of the land is covered with water. Also, water is the primary energy source available.
Hydro Power Plant
While learning about hydraulic machines, one of the most important hydraulic machines to be studied is the Hydroelectric power plant which generates hydroelectric energy or hydropower energy.
Components of Hydroelectric Power Plant
The hydroelectric power plant utilizes the kinetic energy developed by gravitational potential energy due to falling water. The main part of the hydroelectric power plant is a water turbine generator.
The important parts of the hydroelectric power plant are:
The reservoir: It is the part where the water will be stored.
The turbine: The equipment used to generate kinetic energy as soon as the waterfall from a height.
Generator: It will generate electricity by converting mechanical energy into electrical energy.
Powerhouse: It will store all the electricity generated and then it will distribute through transmission lines or the power lines.

Working of Hydroelectric Power Plant
The potential energy stored in the water of the reservoir stored at a higher level will release as kinetic energy as it falls to the lower level.
Water from the reservoir will be made to fall on the turbine in such a way that the force due to the waterfall will result in rotating the turbine.
The turbine is further connected to the generator, then the generator will generate electricity. The electricity produced is also known as the hydroelectric current or hydropower.
This is how hydroelectric power plants work and hence produce electricity which is further transmitted through transmission lines as per the need.
