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 given graph illustrates information about the figuration and operation of the hydroelectric

power

station

to generate electricity.

Overall

, the hydroelectric

power

station

creates energy by a circular process with 2 main stages.

Additionally

, the result of the project generates energy for the national grid. During the day time, The dam is constructed on the river, which creates a high-level

reservoir

to accumulate

water

.

Then

, it starts the process through an intake, which is situated at the lowest part of the dam. When the dam opens

, their action makes a generator produce electricity for the national grid via the

Finally

, the

Then
