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 diagram illustrates the process of
electricity
generation in a hydroelectric power station, highlighting both the daily and nightly operations.
During the day
, water
from a high-level reservoir
flows through an intake, which is open during the day
,
and moves towards a power station. Remove the comma

This
flow of water
turns reversible
Change preposition
into reversible
turbines
, which are connected to a generator. As the turbines
spin, they generate electricity
, which is then
transmitted through power lines to the national grid.
At night, the intake is closed, and the process is reversed. The reversible turbines
, now functioning as pumps, move water
from a low-level reservoir
back up to the high-level reservoir
. This
process requires electricity
, which is often supplied by other sources when demand is lower, ensuring that water
is available in the high-level reservoir
for the next day
's electricity
generation.
The dam plays a crucial role in maintaining the water
levels, while
the reversible turbines
enable the dual functionality of generating electricity
during the day
and pumping water
at night.Submitted by checkmyessay9 on
