Welcome to ESO
We are the electricity system operator for Great Britain, making sure that Great Britain has the essential energy it needs by ensuring supply meets demand every second of every day.
Regional Energy Strategic Planner (RESP) role
Ofgem has announced that the Future System Operator (FSO) will be taking on a new role as the RESP to ensure energy networks are regionally coordinated across fuel vectors and between geographies.
Balancing the Grid - Interactive game
To give you some insight into the world of balancing the grid, we’ve developed a game where you can attempt to keep the grid stable while facing some of the challenges our control room operatives experience daily.
Our Demand Flexibility Service is back - enabling households and businesses to earn rewards for shifting electricity usage outside of peak demand hours this winter.
Join our webinars on 11 December or 13 December to hear our plans to become the independent, whole energy, Future System Operator (FSO) and the role you can play in achieving a net-zero energy system.
