The diagram illustrates various process involved in producing electricity using hydroelectric power station, where water is used as the main source.

The diagram illustrates various process involved in producing electricity using hydroelectric power station, where water is used as the main source. In general, hydroelectric station operates round the clock and reversible turbines plays a key role. During day time it is used to operate generator and act as water pump during nighttime to push water back to dam. The very first process is to collect the river water in high-level reservoir using a dam. Water flow is controlled by a dam intake, its opened during day and closed at night. When intake is opened, water flows downward into reversible turbine with extreme pressure. This pressure operates the generator to produce electricity and at the end of this flow, water reaches low-level reservoir. Power lines were used to transmit the electric current to national grid. During nighttime, water from low-level sent to high-level reservoir in order to reuse the water for next day. Reversible turbines is used again in anti-clock wise direction to suck water from low level reservoir and pump to high-level through same channel.
