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 diagram outlines the
process
of
electricity
production in a hydroelectric
power
station
. The
process
begins when the
water
flows
from the
river
into a high-level
reservoir
and ends with the transmission of
electricity
to the national grid. In general, the
process
is broadly distributed into
day
and
night
stages with the daylight stages involving
electricity
production from a
river
and storage of
water
in a
reservoir
. At
night
, the
water
flows
back in the opposite direction towards an initial
reservoir
and the
river
. The
day
stage of the
process
involves channelling the
river
water
into a high-level
reservoir
backed up by a dam. There is an intake area leading to the
power
station
that opens during the
day
and closes at
night
.
Water
flows
during the
day
to generate
electricity
through the
power
station
turbines. The generated
electricity
is
then
sent to a national grid through
power
lines
while
the excess
water
runs to a low-level
reservoir
. During the
night
stage, the
water
stored in the low-level
reservoir
is reverted to the
power
station
and the turbines of the generator pump it back into the high-level
reservoir
which is closed during the
night
. The
river
water
is stored at the upper level and later it
flows
down, starting the cycle again.
