Running our network
We are responsible for keeping the electricity network, consisting of over 7000 kilometres of overhead line, 22,000 pylons, 2500 kilometres of underground cable and 350 substations, up and running.
Maintaining safe and secure electricity supplies is our number one priority. Find out more about our work.
Substations, pylons and overhead lines
Our electricity grid is comprised of an ingenious network of physical infrastructure that transports power to schools, homes, and business all across the country.
Our control centre
Our control room is responsible for keeping the lights on in England and Wales 24 hours a day, 365 days a year.
Storms, flooding and bad weather
Weather events can be severe and cause damage to electricity networks, but our engineers work 24/7 to keep the lights on whatever the weather.
Protecting the natural environment
We work hard to ensure the reliability of our network, whilst seeking to minimise our impacts on natural habitats as best as we can.
