Hydroelectric power plant (Hydel plant) utilizes the potential energy of water stored in a dam built across the river.
Time needed to build and finish a hydroelectric plant is too long it may take 18 years.

Layout and working of hydroelectric power plant The above image shows the typical layout of a hydroelectric power plant and its basic components .

At the end, there is a turbine and the water spins it, which moves the shaft, that moves the generator, making electricity. Hydroelectric power plant requires water reservoir these plants are constructed near big dams. Disadvantages of hydroelectric power plant: Nothing is perfect, so it’s ordinary to meet some drawbacks of hydroelectric power plant like: The investment and upfront capital cost is high, it reaches 20 billion $. Hi friends, in this article, I am discussing the working principle of hydroelectric power plant, and I hope you will appreciate it.. A power plant that utilizes the potential energy of water for the generation of electrical energy is known as a hydroelectric power plant. HYDROELECTRIC POWER AND WORKING PRINCIPLE It is the power generated by water, using its gravitational force when it is flowing or falling. Water stored in dams has potential energy. Dam and Reservoir: The dam is constructed on a large river in hilly areas to ensure sufficient water storage at height. The potential energy of the stored water is converted into kinetic energy by first passing it through the penstock pipe.

Hydroelectricity is the most widely used form of renewable energy.It is a flexible source of electricity and also the cost of electricity generation is relatively low. Hydroelectric Power Plant: In 2012, hydroelectric power plants contributed about 16% of the total electricity generation in the world.
Hydroelectric power plant Working principle. Water under pressure carried by pen-stock and supplied to the turbine through the inlet value pen stock is the pipe made up of steel or concrete. Water is moved from a higher elevation point to a lower elevation point through a large pipe.
