The diagram outlines the process of electricity production in a hydroelectric power station. The process begins when the water flows from the river into a high-level reservoir and ends with the transmission of electricity to the national grid.

In general, the process is broadly distributed into day and night stages with the daylight stages involving electricity production from a river and storage of water in a reservoir. At night, the water flows back in the opposite direction towards an initial reservoir and the river.

The given diagram depicts the process of generating electricity in a hydropower plant. The process begins with storing water from the river in a high-level reservoir and ends with the transmission of generated power to the national grid.

In general, this hydrostatic power station consists of 3 main units, namely- the high-level reservoir, the power station, and the low-level reservoir.

The diagram illustrates the production of electricity by harnessing the power of water in a hydroelectric power station.

Overall, the electricity generation in this station involves a sophisticated procedure of 6 stages. Moreover, it requires a few instruments such as a reservoir for storing water, reversible turbine, generator, power lines and so on.

The day stage of the process involves channelling the river water into a high-level reservoir backed up by a dam. There is an intake area leading to the power station that opens during the day and closes 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.

As can be seen in the diagram, during the daytime, intake at the bottom of the dam of the high-level reservoir is kept open to allow water to flow down to the power station and pass through the turbines to the lower reservoir. A power generator coupled to the turbine generates electricity and then it is transmitted to the national grid via power lines. The water is stored in another reservoir next to the power station. The produced electricity is then sent to a national grid through power lines while the excess water runs to a low-level reservoir.

During the night time, the stored water is pumped back to the high-level reservoir with the help of the reversible turbine that acts as a water pump. We can see that the intake valve is closed in the nighttime while water is being pumped back.

The first stage of the process involves channelling the river into a high-level reservoir backed up by a dam. There is an intake area leading to the power station that is open during the day and closes at night. Water flows during the day to generate electricity through the power station turbines and the resulting electricity is sent to a national grid through power lines while the water then continues to a low-level reservoir.
The reversible turbines that operate the generator during the day allow the station to pump the water in the low-level reservoir back into the high-level reservoir for use the next day.

The process begins with storing water from the river in the high-level reservoir, which is situated behind a dam. During the day, the dam allows the flow of water via pipes to the turbine that is connected to a generator. The extreme flow of water rotates the turbine, and thus produces electricity in the generator, which is supplied via power lines to the National grid. The used water, on the other hand, is transferred to the low-level reservoir for storage.

When the night comes, the stored water is shifted by means of reversible turbines that help to pump the water uphill to the high-level reservoir which is closed during the night. The river water, on the contrary, is stored at the upper level and starts the process anew when it flows down.
