National Energy System Operator
The UK’s 2023 Energy Act set the legislative framework for an independent system planner and operator to help accelerate Great Britain’s energy transition, leading to the establishment of the National Energy System Operator (NESO).
NESO will take a whole system approach, looking across natural gas, electricity and other forms of energy to fulfil our primary and secondary duties as described in the Energy Act. We will engage participants in all parts of the energy ecosystem to deliver the plans, markets and operations of the energy system of today and the future. We refer to these participants as NESO's customers and they include industry, communities, consumers and other stakeholder groups.
NESO is built on our previous experience as the Electricity System Operator (ESO). The ESO had extensive expertise in balancing electricity supply and demand 24/7, while making sure network operations and the markets were prepared for the future. The transition to NESO requires a significant expansion in our capabilities and we are transforming our organisation to meet this challenge.
