Hydroelectric power plants convert the power of flowing water into electricity. The amount of energy in flowing water is determined by flow or drop rate of water. Water flowing in a large river has a lot of energy. Similarly, when water is dropped from a very high point, it would generate a high amount of energy. Water that is put into ducts or pipes in one of the ways mentioned above flows into the turbines, allowing the turbines to rotate for power generation by means of its blades. Turbines are connected to generators and convert mechanical energy into electricity.
Hydroelectric power plants are the most important sources of energy since
– they generate power from water, which is a renewable source,
– they do not contribute to greenhouse gas emissions,
– they allow construction using national resources,
– they have a long technical working life and no fuel expense,
– their operation and maintenance costs are low,
– they create employment opportunities, and
– they revive the economic and social life in rural areas.
