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. Write at least 150 words.

The design presents the method of

electricity

generation in a hydroelectric

power

station

. The leading part of the process is done in the

power

station

which generates

electricity

. The

station

has three main sections to produce

electricity

- the high-level

reservoir

,

power

station

and the low-level

reservoir

- that use

water

from the river to produce

electricity

, and the produced

electricity

is

then

transferred to the national grid.

Initially

, the river

water

flows into the dam through the high-level

reservoir

.

This

flow of

water

generates

electricity

in the daytime, and

this

water

is stored in the turbine. The turbine helps to operate a generator in the daytime. During the night phase, the excess

water

saved in the low-level

reservoir

is returned to the turbine.

Then

the

water

is sent back into the low-level

reservoir

which remains closed at night.

This

flow of

water

helps the

power

station

produce

electricity

. The generated

electricity

is

then

sent to the national grid through

power

lines

while

the excess

water

runs to a low-level

reservoir

.
