The image illustrates a hydroelectric power station schematic featuring a river leading into a high-level reservoir behind a dam. Water intake operates as open during the day and closed at night. During the day, water flows down to generate electricity via a generator, with power lines transmitting electricity to the national grid. At night, water flows in reverse to fill the high-level reservoir through reversible turbines, with the generator transitioning to pump water upwards. The schematic also indicates a low-level reservoir storing water when not being pumped back up.
Given the complexity of the image, the above description may not be entirely accurate.

The diagram illustrates the process of electricity generation in a hydroelectric power station. Summarily, it can be seen that water flows from the high level resorvoir during the day to create electricity and is pumped back from the low level reservoir at night.
Firstly, water flows from the river into a high level reservoir walled by a dam. During the day, water transits through an intake and moves downward into the reversible turbines to generate power and ends up in a low level reservoir. As a result, generated power is sent to a generator that supplies power to the power lines and the national grid.
On the other hand, water from the low level reservoir is pumped at night with the aid of the reversible turbines and moves upward into the high level reservoir where it is stored to repeat the same process during the daytime.
