The diagram below shows how electricity is generated in a hydroelectric power station. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The given diagram illustrates various components and processes involved in the generation of electricity in a hydroelectric power plant. Overall, on the one hand, there are 5 stages involved during the day to generate electricity starting from a high-level reservoir and ending in the National Power Grid. On the other hand, during the night, water is pumped back to the high-level reservoir so that it can be reused the next day to generate electricity. The main components of Hydroelectric Power Station include a high -level reservoir, a channel for the flow of water, reversible turbines, power lines, and a low -level reservoir. Fast flowing river water flows to the dam where water gets stored in the high-level reservoir. During the day, intake gates of the Dam are opened to allow the flow of water, through the channels to the low-level water reservoir assisted by gravity. Before the water reaches the reservoir, the fast-flowing water passes through the turbines, situated just before the reservoir. These turbines, rotated by the force of water in turn, generate electricity which is then transported to National Power Grid via power lines. During the night, however, water flows in the opposite direction as it was in the morning. Water is pumped up from the low-level reservoir to the high-level reservoir, across the channel with the help of the reversible turbines which act as a pump during the night. The same water is then flown to the low-level reservoir the next day and the cycle continues.
