Our role in the industry
We hold a role right at the heart of the energy industry as the owner of the high-voltage electricity transmission network in England and Wales.
The transmission network is like the motorways and dual carriageways of the electricity system, while the distribution system is like the smaller roads that deliver the electricity to homes and businesses.
The traditional model of the industry
Traditionally, electricity has been generated through sources that include fossil fuel and nuclear power stations, or renewable sources such as wind and solar. Those generation sources connect to the transmission network, which transports the electricity to the distribution system. It’s then delivered by the distribution system to consumers at a voltage they can use.
How the traditional model is evolving
Today, the traditional model of the energy sector is evolving and adapting to unprecedented transformation, in which we are moving from high to low carbon. Coal plants are closing down, while renewable sources of generation are increasing significantly, together with technologies such as battery storage.
Smaller-scale sources of generation such as wind and solar are also connecting directly to the distribution network, creating a more complex system to manage. And consumers are using new technologies to manage their electricity demand – increasing energy efficiency in homes and businesses.
There’s now a greater diversity of supply and flexible demand than ever before. The electricity transmission network has a crucial part to play in the future energy mix, connecting new sources of energy to the people who use them.
