Hydro Power Plant:

Dams are constructed at heights to obstruct the flow of water and store it. The stored water has Potential Energy. Water stored in heights now is allowed to flow to low levels. This is called Hydroelectricity because the potential energy of water, which is stored at elevated heights, is converted into kinetic energy of flowing water, which in turn is converted electricity. It is a renewable source of energy, since rainfall comes over and over again.
