Summarise the information by selecting and reporting the main features, and make comparisons where relevant. The diagram below shows how electricity is generated in a hydroelectric power station.

Conversely
, in the night, the process is totally different and
electricity
generation will be stopped. The
water
will be pumped from the low-level
reservoir
to the high-level
reservoir
via the reversible turbines.
Besides
, the intake valve keeps closing. During the day, there are three steps to produce
electricity
. It is obvious that a dam stands in front of a river, which leads to a high-level
reservoir
.
First
,
water
from the high-level
reservoir
flows to the
power
station through the tube as the intake is open. Following
this
, in the
power
station, the
water
can spin the reversible turbines to generate
electricity
.
Consequently
, the
electricity
is sent to the national grid through
power
lines and the
water
finally
flows into the low-level
reservoir
. The photograph illustrates how a hydroelectric
power
station works to generate
electricity
. Overall, there are opposite processes in the day and night and
electricity
generation occurred in the daytime.
