Description

About the role

National Energy System Operator (NESO) recognises the potential of bright and talented individuals, and we encourage you to join us as Great Britain’s energy system undergoes an ambitious, exciting, and vital transformation. Together with industry, we are creating a cleaner, more sustainable energy future.

We’re looking for passionate and skilled Security of Supply Modelling Specialists x4 to join our Energy Security Modelling team. The team play a pivotal role in ensuring the energy security of Great Britain. We develop cutting-edge modelling to provide expert advice to Government on critical decisions related to security of supply, policy targets and future policy development.

Three successful candidates will lead the design and development of bespoke in-house energy market models, supporting key obligations relating to target capacity recommendations for the Capacity Market auctions. The fourth will join our team of PLEXOS experts, focusing on modelling the contribution of interconnectors to security of supply. All roles offer the freedom to innovate—driving forward methodologies and enhancements that keep our modelling world-class and fit for the future

This isn’t just modelling, it’s mission-critical work. We speak directly to government to inform decisions on how much electricity capacity to secure through the GB Capacity Market—currently worth around £3 billion annually. You’ll be helping to answer questions like:
How much electricity capacity do we need five to eight years from now? What mix of technologies will keep the lights on through the energy transition?

You’ll lead the development of cutting-edge modelling, shape the annual Electricity Capacity Report, and engage with key stakeholders including DESNZ, Ofgem, and the Panel of Technical Experts. You will bring fresh thinking to how we model uncertainty, risk, and resilience in a rapidly evolving energy landscape

This role will be based in Warwick (we also have our Wokingham and Glasgow offices, you would expected, where possible, to travel to Warwick or other locations for specific in-person collaboration events). We continue to offer hybrid working from office and home. This is a full-time role, and we offer flexible working arrangements.

About Us

National Energy System Operator’s (NESO) mission is to facilitate the decarbonisation of Great Britain’s energy network and ensure the delivery of reliable, affordable, and clean electricity for consumers. We work with stakeholders across the whole energy industry to plan for future network needs, using a wider adoption of technology and changes in consumer behaviour, as well as ensuring we have the right markets, networks, and frameworks in place, to transform the way we operate tomorrow.

Join us, and let’s energise progress.

energy, our future, together.

About The National Energy System Operator (NESO)

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 Britain’s 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. As NESO, we will build on our existing roles, capabilities, and ways of working significantly to create an organisation the energy system and its users’ need. Our new capabilities will enable us to look across vectors, including electricity, natural gas and hydrogen, and crucially consider…
