KS3 The National Grid

The national grid is the network of high-voltage power lines between major power stations.

• True

• False

What is happening at stage 1 in the diagram?

• fuel is burned to boil water to make steam

• steam makes a turbine spin

• the spinning turbine turns a generator which produces electricity

• the electricity goes to the transformers to produce the correct voltage
