Your Energy, Your Future, Our Purpose
We are the National Energy 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.
The UK’s 2023 Energy Act established an independent system planner and operator to help accelerate Great Britain’s energy transition; creating the National Energy System Operator (NESO).
NESO is built on our previous experience as the Electricity System Operator (ESO), where we had extensive expertise in balancing electricity supply and demand 24/7, whilst making sure the networks we operated and the markets we served were prepared for the future.
Introducing NESO
Fundamental to NESO is the ability to bring an independent, impartial voice to energy system planning and operations that takes this whole system view. We’ll consider all the interrelated challenges and trade-offs and ultimately work towards optimal outcomes for energy consumers.
We bring together eight activities required to deliver the plans, markets and operations of the energy system of today and the future. Bringing these activities together in one organisation encourages holistic thinking on the most cost-efficient and sustainable solutions to the needs of our customers.

About NESO
