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. Depending on the type of hydraulic power plants kinetic and/or potential energy of water is used to generate electricity.The Kinetic energy possessed by water rotates dynamo shaft which in turn rotates the dynamo. By the principle of electromagnetic induction, E.M.F is induced in the dynamo. This e.m.f is responsible for generating electric current.
Thus, finally the current induced is transmitted to nearest power station , and further through power lines.
