Future Energy Scenarios - ESO Pathways to Net Zero

The evolving dynamics of the energy system call for decisive action within the next two years to deliver the fundamental changes required to achieve a fair, Foreword affordable, sustainable and secure clean energy system by 2050. This means we must prioritise steps that will enable the delivery of cleaner, cheaper energy generation whilst ensuring a resilient system that delivers security of supply for consumers.

As the Electricity System Operator (ESO), we have

set a target to be able to operate a net zero carbon electricity system for short durations by next year, which sets us up to be able to operate a clean power system throughout the year in the 2030s. Ongoing global conflict continues to create international uncertainty in energy markets, with the long-term consequences yet to be determined, and the cost-of-living and energy crisis continues to impact households and businesses across Great Britain.

Later this year, we will transform to become the National Energy System Operator (NESO). We will put our customers, homeowners, businesses and local communities at the heart of our work; building on the strong foundations of the ESO we will deliver a future where everybody has access to clean, reliable, affordable energy.

As NESO, we will take a holistic approach to planning and facilitating whole energy system decarbonisation. We will be involved in the strategic planning of gas and electricity networks, integrating them for the first time

to develop a comprehensive whole system plan for future network development. We will develop a whole energy system view of future market direction so we can recommend actions to optimise markets across vectors and reduce costs for consumers. And we will also provide independent advice to Government and Ofgem on energy policy developments.

Decarbonisation of the energy system is the challenge of our generation. In recognition of the expansive industry transformation required to Great Britain’s energy network planning, this year’s Future Energy Scenarios (FES) framework has evolved from ‘scenarios’ to ‘pathways’ to explore narrower ranges and strategic, credible choices to propel us on the route to decarbonisation. This transition has also been reflected in our new publication name - Future Energy Scenarios: ESO Pathways to Net Zero.

FES creates the foundation upon which our future network investment plans will be built. We look forward to working with industry, the Government, Ofgem and our stakeholders and customers as we transition to NESO and build upon our analysis and insights to deliver on our critical role for society and the economy.
