About NESO
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.
What is NESO’s role in the energy system?
NESO lies at the heart of the energy system as an independent, public corporation with responsibilities for planning and operations. This is the first time in Great Britain that one organisation will plan and operate the whole energy system.
Our impartiality and whole system perspective mean we can make recommendations that balance the needs of everyone across Great Britain, so that we all benefit from the growing number of options we have for cleaner, cheaper, more secure energy.
We will enable solutions that are fair for all, so that – together – we can take collective action to make a lasting difference and inspire generations to come.
