Our Network

National Grid Electricity Distribution (NGED) manage a network of 220,000 km of overhead lines and underground cables, and 185,000 substations to provide power to millions of people.

We transfer power safely and securely from the National Grid to millions of homes and businesses in the Midlands, South West and Wales. Our network of overhead lines, underground cables and substations transforms power from the 400,000 volts supplied by the National Grid to the 230v you need to power your home.
