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, the river flows to the high-level reservoir behind a dam in order to accumulate. Under the dam there is an intake, which is open in days and closed in nights. During day time the water flows through the intake to generate electricity. when receiving to reversible turbines, generator is operated in power station. Then, the electricity goes through power lines to the national grid.
During night time, the water that was reserved in low-level reservoir during day flows back to the reversible turbines to pump the water into high-level reservoir.
