power station to consumer. Put the statements in the correct order.
The first one has been done for you.

a) It is fed to substations.
b) It is stepped up by a transformer to high voltages for long-
distance distribution.
c) It is distributed via the grid to supply points.
d) It is distributed to the domestic consumer.
e) Electricity is generated at the power station at 25 kV.
f) It passes via the switching compound to the grid.
g) It is distributed via overhead or underground cables to
intermediate substations.

Step 8

Mark the sequence of stages using appropriate sequence words
where you think this is helpful. Add the following information to
your statement and make them into a text.
1. At the main grid supply points, power is stepped down to 33kV
for distribution to heavy industry.
2. At intermediate substations, power is reduced to 11 kV for light
industry.
3. At the distribution substations, power is stepped down to 415
V. 3-phase, and 240 V, 1-phase.

Step 9

The two texts, which follow describe two plants for generating
electricity from wave power. Note the similarities and differences
between the plants.

WAVE POWER

This prototype wave-power plant on the Scottish island of
Islay was constructed by building a concrete water column across
