National Grid

What is the National Grid system?

Established in 1933, the National Grid is the heart of the UK’s energy supply. Made up of a number of networks and local power stations, the National Grid transports gas and electricity throughout the country to every city, town, village and home in the UK from its central hub in Berkshire. Owned by National Grid plc (formerly National Grid Company), the National Grid system is comprised of separate gas and electricity companies.


How does the National Grid work?

This incredibly complex system consists of a comprehensive network of power plants and lines, gas pipelines, interconnectors, storage facilities, substations and distribution companies called Distribution Network Operations (DNOs). These come together to form the National Grid system with branches stretching across the entire country to deliver essential gas and electricity.


How is electricity delivered to consumers?

It all starts at the power plant where generators feed electrical current through a number of transformers, in order to create enough voltage to propel the power across long distances. Throughout its journey, this electrical charge travels through high 132 voltage transmission lines across the UK (those lines which you sometimes see stretching across our streets and countryside) to arrive at local DNOs. The Distribution Network Operators then connect the power to individual homes and buildings via a meter which records usage.
