From hospitals to households, telecoms to transportation, our society relies on electricity. Our control centre makes sure there is always a reliable and safe supply, moving megawatts around the country to keep the lights on.

The ESO's Electricity National Control Centre (ENCC) is GB’s centralised hub for electricity system operation. Its role is to move electricity around the country from where it’s generated to where it’s needed.

Like air traffic controllers, our engineers work 24/7 to ensure demand and supply are always in balance. We monitor the electricity system in real time, intervening when needed to make sure everything runs smoothly.

The ENCC plays a critical role for the nation. Find out more about its responsibilities, including what the ENCC does, how it handles severe weather events and more.
