The image illustrates the flow dynamics of water and electricity in a pumped storage hydroelectric system with components detailed as follows: water flows from a river into a high-level reservoir via open intake during the day and closed intake at night; water descends from the high-level reservoir for electricity generation during the day through a dam and flow line into a power station containing reversible turbines; the reversible turbines perform electricity generation during the day and reverse to pump water back to the high-level reservoir at night. Power lines connect the power station to the national grid; excess and pumped water are stored in a low-level reservoir for nighttime operations.
Given the complexity of the image, the above description may not be entirely accurate.

The diagram illustrates the process of generating electricity in a hydroelectric power station.
Overall, it is a cyclical process, consisting of four main stages, including storing water in reservoir, flow of it, operating generator to produce the electricity in the day time, and pumping back the water from low-level reservoir to high-level one at night.
First of all, a river is led to the high-level reservoir right behind a dam with an intake connected to the supply. During the day, it is open, thus the water flows downwards to reach the low-level reservoir. A reversible turbine, in day time, pumps up the water to the generator in the power station, which leads to operate it and generate the electricity and send it to power lines and national grid.
Following this, the water that is stored in low-level reservoir, flows back to the turbine, that pumps it into high-level reservoir during the night.
