The diagram outlines the process of electricity production in a hydroelectric power station.
Overall, the process is broadly distributed into day and night stages with the daylight stages involving water intake from a river and storage of water in a reservoir. At night, the pumped water flows back in the opposite direction towards the high-level reservoir and the river.
The day stage of the process involves channelling the river water into a high-level reservoir backed up by a Dam. Underneath the Dam there is an intake area leading to the power station that opens during the day and remains closed at night. Water flows during the day to generate electricity through the power station turbines. The generated electricity is then sent to a national grid through power lines while the excess water runs to a low-level reservoir.
During the night stage, the water stored in the low-level reservoir is reverted to the power station and the turbines of the generator pump it back into the high-level reservoir which is closed during the night. The river water is stored at the upper level and later it flows down, starting the cycle again.
