Large dams trap the water in reservoirs to create the necessary fall height and to store some water for later use. The water falls to a lower level, passing through the turbine. The turbine axel rotates and powers the generator. The generator converts the rotating movement of the turbine into electrical energy. The transformers regulate the voltage so it is appropriate for the power grid.
Long useful life and low operating costs
Hydro power plants are expensive to build. But once the plant is in operation, hydro power is extremely inexpensive. The plants are almost entirely automated, no fuel needs to be purchased and maintenance costs are low. In addition, the useful life of a hydro power plant is long. Many of the plants in operation today were built over 50 years ago and their useful life will continue for many years to come. Investment costs are quickly recouped once the plant is in operation.
Hydro – a balancing power
Hydro power plants can be used both to generate baseload power (the amount of electricity that is always needed) and as balancing power (electricity output that can quickly be turned on to meet variations in demand).
A problem with electricity is that it cannot be stored to any great extent. Water, on the other hand, can be. Water reservoirs next to hydro power plants function as large "batteries". Energy can be stored during the times of the year when water inflow is high and electricity demand is low, and the energy can then be used when demand is greatest.
Output can be turned on quickly
An important characteristic of hydro power is that it generates a great deal of electricity as soon as the water is released, and is not dependent on weather, wind or long, complicated start-up processes, a characteristic not shared by many other types of energy. Hydro power generation can be increased, for instance, to cover shortfalls from wind power and other types of energy that cannot be directly controlled, or from nuclear and coal power plants which take longer to get started.

Here is your answer mate !!
A power station where the kinetic energy of flowing water in river is converted to electrical energy is called Hydroelectric Power plant. And the electricity produced is called Hydroelectricity.
