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.
