What we do

Find out about National Grid’s pivotal role in the energy industry, helping make sure gas and electricity reaches homes and businesses from where it’s produced, and enabling the transition to a clean energy system.  

What we do in the UK and US

National Grid is an energy company operating in the UK and the US. We play a vital role in connecting millions of people to the energy they use. We enable the innovation that is transforming the energy system.


The UK

  • We own the high-voltage electricity transmission network in England and Wales. We’re responsible for making sure electricity is transported safely and efficiently from where it's produced to where it's needed.
  • The Electricity System Operator is a legally separate business, balancing supply and demand to ensure homes and businesses in Great Britain have the electricity they need 24/7.
  • We also own and operate the gas national transmission system in Great Britain, ensuring gas is transported safely and efficiently from where it's produced to the places it's consumed, balancing supply and demand day-to-day.
