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 as we move megawatts around the country.

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.

Balancing programme

This programme was established to develop the balancing capabilities that the Electricity National Control Centre needs to deliver reliable and secure system operation, facilitate competi
Strategic capability review

Under the RIIO-2 business plan, the ESO has transformational ambitions which deliver significant benefits, many of which are dependent on enhanced balancing capabilities in our Electricity National Control Centre (ENCC).

How does the ENCC handle severe weather?

As soon as we see a storm coming, we immediately work to prepare and sometimes stabilise GB’s electricity system.
What does a day in the ENCC look like?

Our engineers and experts work around the clock to make sure that the right amount of electricity gets to where it’s needed, when it’s needed.
