National Grid Electricity Transmission

We own and maintain the high-voltage electricity transmission network in England and Wales. Every time a phone is plugged in or switch is turned on, we’ve played a part, connecting you to the electricity you need. 

We're investing in the network to help connect and more low carbon electricity, transporting it through our power lines and substations so it reach homes and businesses. It’s a crucial role and pivotal in turning the UK’s net zero ambitions into reality.

What is a pylon?

Pylons – also known as electricity transmission towers – are the structural supports that have carried the UK’s network of high-voltage overhead power lines for nearly 100 years.

Our 2021–2026 Environmental Action Plan

Our environmental vision is to build a sustainable electricity network, which makes a positive contribution to the environment.
