hydroelectric power plant uses the force of falling water for electricity generation. The basic working of hydroelectric power plant is as follows
The theory is to build a dam on a large river that has a large drop in elevation . The dam stores lots of water behind it in the reservoir. Near the bottom of the dam wall there is the water intake. Gravity causes it to fall through the penstock inside the dam. At the end of the penstock there is a turbine propellor, which is turned by the moving water. The shaft from the turbine goes up into the generator, which produces the power. Power lines are connected to the generator that carry electricity to your home and mine. The water continues past the propellor through the tailrace into the river past the dam.
