The transmission network is responsible for transporting electricity across the country, from its point of generation into our local networks. Distribution networks are responsible for the local systems, transporting electricity from transmission through to end customers.
Across England, Wales and Scotland, there are three Transmission Owners. They are responsible for the national high voltage networks and transmission connections. National Grid Electricity Transmission manages England and Wales, with Scottish Power (SP) Transmission and Scottish & Southern Electricity Networks (SSEN) Transmission in Scotland.
Larger projects connect directly into the high voltage transmission networks, including onshore and offshore wind farms, solar farms, battery storage, tidal power, nuclear- and gas-powered generators.
Interconnectors connect directly into transmission networks. They bring power from other countries to help meet demand here or export it in times of oversupply.
Transmission connected demand
Some users may need to take power from the transmission network to supply networks or industrial centres.
Large consumers of electricity, such as steel manufacturing, data centres, or the railway can connect directly to the high voltage transmission system.
District Network Operators ensure that the local lower voltage networks which supply domestic homes and businesses are working effectively. They maintain their own network assets and connect their own users via their own infrastructure.
The differences between high voltage electricity transmission and distribution connections can be varied and complex. Find a more detailed perspective here.
