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 process describes how the people created an electricity in a power station make by water.
In general, there are multiple stages in this linear process, commencing with river water came to a high-level tank and concluding with electricity conveyed to country-wide grid.
The diagram commences when the water in river is flowed into high-level reservoir. The second stage is that the intake is opened in daytime and closed in nighttime allows flow of water to generate electricity in day. As soon as this stage is complete, reversible turbines are activated to operate generator. After, the power lines are created, electricity is transmitted to national grid.
The process continues when flow of water is conveyed into a storage in a daytime but in the nighttime, it is transmitted to reversible turbines which create a push to pump water into high-level reservoir, ready for daytime activities.
