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. Write at least 150 words.

The diagram depicts data on how

electricity

is being made in a hydroelectric

power

plant.

Overall

, it not only explains how

electricity

is being made in the daytime but

also

gives information on recycling consumed

water

during the night.

To begin

, the

water

of a river is stored behind a high-level dam.

Following

this

, during the day an intake opens up and a pipe transfers

water

towards the

power

station, where currents of

water

make the turbines rotate and produce

power

.

This

power

is

then

fed into the generator and

that is

how

electricity

is made. After its production, travels through

power

lines and is delivered to the national grid. At night, the mentioned process is reversed and

water

is pumped from the low-level to the high-level reservoir, which happens by taking advantage of

electricity

from the grid and reversible turbines. The flow in the pipe is

also

reversed and the intake is closed during

this

process.
