We develop, own and maintain the physical infrastructure, such as the pylons and cables, needed to move the electricity generated from windfarms and power sources around the country.
We own and maintain the high-voltage electricity transmission network in England and Wales. Every time a phone is plugged in, or a switch is turned on, we’ve played a part, connecting you to the electricity you need.
We take electricity generated from windfarms and other power sources and transport it through our network of pylons, overhead lines, cables, and substations. It then goes on to separate lower voltage local distribution networks, which connect directly to homes and businesses.
We're investing for the future, connecting more and more low carbon electricity to our network - it’s a crucial role and pivotal in turning the UK’s net zero ambitions into reality.
Working with the Electricity System Operator we help large energy projects connect to the transmission system so their electricity can flow through the network and power homes and businesses.
We are investing to upgrade the electricity transmission system in England and Wales. New infrastructure such as overhead lines and substations will connect increasing amounts of low carbon power.
Our teams are responsible for keeping the electricity transmission network, consisting of over 7000 km of overhead line, 22,000 pylons, over 700 km of underground cable and 300 substations, up and running.
Delivering the carbon-free electricity network of tomorrow means innovating today. We’re working with industry to find new ways to tackle some of the biggest challenges in energy.
Here you will find information about National Grid's history, including how our network came together to form the first grid system in the world.
