Hydropower Generation Through Reservoir
Principle of Hydropower Generation
Water cycle in nature
Water cycle in the hydraulic power plant
- The water in rivers posses two types of energies: kinetic energy and potential energy.
- The energy of water due to its motion is called as kinetic energy
- The energy of water due to its high level is called as potential energy.
Working Principle of Hydroelectric Power Plant
Various Components of Hydroelectric Power Plants and their Working
The dam is the most important component of hydroelectric power plant. In fact the name ‘dam’ is considered to be synonymous to the ‘hydroelectric power plant.’ The dam is built on a large river that has abundant quantity of water throughout the year. The dam is built at location where the height of the river is sufficiently high so as to get maximum possible potential energy from water.
2) Water reservoir
Water reservoir is the place behind the dam where water is stored. The water in the reservoir is located at the height above the rest of the dam structure. The height of water in the reservoir decides how much potential energy water possesses. Higher the height of water more is its potential energy. The high position of water in the reservoir also enables it to move downwards effortlessly due to gravity.

4) The penstock
5) Water turbines
