The diagram illustrates how electricity is produced in a hydroelectric power station. Overall, it can be observed that the movement of water is utilized between a high-level reservoir and a low-level reservoir through a dam and turbines.
During the day, water is drawn from the high-level reservoir through an intake that is opened during daytime. The water flows downward to the power station, turning reversible turbines that operate a generator. This generator produces electricity, which is then transmitted into the national grid through power lines.
At night, the process is reversed. The intake is closed, and the turbines pump water back into the high-level reservoir using stored energy. This ensures that water is available for the next day.
In summary, the hydroelectric power station generates electricity through the movement of water. This method is an efficient renewable energy source.
