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 Britains 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.

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.
