Who we are

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 take electricity generated from windfarms and power stations and transport it through our network, consisting of over 7000 kilometres of overhead line, 2800 kilometres of underground cable and 350 substations, on to the distribution system, so it reach homes and businesses. 

We're investing in the network, connecting more and more low carbon electricity - it’s a crucial role and pivotal in turning the UK’s net zero ambitions into reality.
