The diagram below shows how electricity is generated in a hydroelectric power station. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram illustrates how a hydroelectric power station generates electricity.
Overall, it is clear that the process involves different stages, beginning with water flowing into a reservoir and ending with electricity transmitting to a national grid.
The procedure commences with river water being held in a high-level reservoir, which is constructed by building a dam to stop river flow and lowering the river bed.
Following that, an intake that is open during the daytime and closed at night allows water to flow to reversible turbines to generate electricity. These turbines turn on a generator in a power station, which produces power lines that are then transmitted to the national grid. Next, during the day, water is released into a low-level reservoir for storage, but at night, it is pushed back into the reversible turbines, which provide a push to pump water back into the high-level reservoir, ready for daytime operations.
