National Grid
In short
The National Grid is the high-voltage network that carries electricity from power stations to homes and businesses across Great Britain.
In plain words
It acts like a massive motorway system for electricity. It moves power from where it is made, such as wind farms, to where people need to use it.
A simple example
When a large wind farm in Scotland generates extra energy, the National Grid sends that electricity down to a house in London.
Why it matters
Without it, electricity could not travel long distances reliably. It ensures the right amount of power is available at the right time to prevent blackouts.
Easy to mix up
People often confuse the National Grid with the electricity companies that send monthly bills to your house.
