A good way to think about the difference between our transmission and distribution operations is to imagine Britain’s road system:

• The transmission network is like the motorways, carrying vehicles (electricity) at high speed (high voltage) across the country. This is the network of big pylons and overhead lines you see around the country.
• The distribution networks are the local roads, connecting motorways with communities to help vehicles complete their journey. These are the smaller pylons (and underground cables) carrying lower voltage lines.

Our transmission business carries high-voltage electricity around on the ‘motorways’ of the network, and our distribution operation uses the ‘local roads’ to deliver it to where it’s needed in the Midlands, South West or South Wales. Read more here
