About us

National Energy System Operator’s (NESO) mission is to facilitate the decarbonisation of Great Britain’s energy network and ensure the delivery of reliable, affordable, and clean electricity for consumers. We work with stakeholders across the whole energy industry to plan for future network needs, using a wider adoption of technology and changes in consumer behaviour, as well as ensuring we have the right markets, networks, and frameworks in place, to transform the way we operate tomorrow.

About the National Energy System Operator (NESO)
In Autumn of 2024, the ESO transitioned to National Energy System Operator, or NESO for short. Previously denoted as the Future System Operator (or FSO), the new National Energy System Operator is the independent body responsible for planning Great Britain’s electricity and gas networks and operating the electricity system.

The ESO, including all of its existing roles, are now at the heart of the new National Energy System Operator. As NESO, we will build on our existing roles, capabilities, and ways of working significantly to create an organisation the energy system and its users’ need. Our new capabilities will enable us to look across vectors, including electricity, natural gas and hydrogen, and crucially consider the trade-offs between them.

The organisation is set up as a public corporation with its own Board of independent directors, with complete operational independence from government, the regulator and any and all commercial interest. As was the ESO, NESO will be licenced and regulated by Ofgem through price control agreements and obligated to identify optimal solutions to system operations and planning in the most sustainable, affordable and secure way for all.

The time to deliver is now. As part of our 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.
