What we do

We operate the Electricity National Transmission System in Great Britain, balancing supply and demand


As the Electricity System Operator in Great Britain, we make sure Britain’s homes and businesses have access to the electricity they need.

This involves managing the network on a real-time basis. We do this by making sure supply and demand are perfectly matched from one second to the next. Our brochure explains this in more detail.

As the ESO adapts, it’s regulatory and incentive framework is changing too. Central to this was the publication of our ESO Forward Plan 2018-19 that sets out the new incentive framework which covers all aspects of the ESO’s role, as defined by Ofgem in consultation with industry. We propose that the roles that were developed should form the starting point for RIIO2.
