Hydroelectricity power plant

This diagram below represents, the pictorial presentation of hydroelectric power station. It shows how electricity generates. The river flows from the high level reservoir to lower level. It intakes depend upon the time period whether it is a day or night. During the day, dam warrior allows water to meet the power station in which their is a generator. From where electricity generates and provides to power lines through which it supply start to national grid. Whilst in the night time, it functioning works autonomous. From the down stream it goes to reversible turbine. It pumps water into the same passage and meets the river. This process continues during the generation of electricity
