The Government and Ofgem have asked the ESO to take on new roles and responsibilities.

Becoming the Energy Future System Operator is a critical step to help deliver a reliable and clean energy transition for all. The ESO, including all of its existing roles, will be at the heart of the new Future System Operator, taking on additional roles with a whole energy system mindset to drive progress towards net zero while maintaining energy security and minimising costs for consumers.

The new organisation will be set up as a public corporation with operational independence from government – bringing parties together to support optimised decision making and action. As now, it will be licensed and regulated by Ofgem through price control agreements. It is anticipated that the new organisation will be up and running by or in 2024.  

The time to act on climate change is now. As part of the team, you won’t just be touching the lives of almost everyone in Great Britain – you’ll be shaping the way we use and consume energy for generations to come.
