Whole Systems Forecasting Analyst

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. NESO are now looking for a RESP Whole Energy Forecasting Analyst to be part of our growing Regional Energy Strategic Planning (RESP) team. In this exciting role you will play a crucial role leading the development of our approaches to whole energy regional pathways modelling and analysis, working collaboratively with a wide range of stakeholders. You will model and analyse demand and supply scenarios at distribution level across different vectors such as hydrogen, biomethane, electricity and sectors such as Industry, heat, transport, consumer as well as whole system modelling. You will develop transparent consistent assumptions with industry experts and lead inputs into the RESP methodology. As an analyst you will build an understanding of different parts of the energy industry, conduct research and analysis and explain results to stakeholders. This role can be based from Warwick and we continue to offer hybrid working from office and home. We are open to full time and part time applicants as well as flexible working arrangements.

About Us

The creation of National Energy System Operator (NESO) is driven by an urgent need to unify and optimise our approach to energy. A more integrated and coordinated strategy is needed to meet the unprecedented challenges of climate change, ensuring secure energy supply, and keeping costs manageable for consumers. Join us and empower your potential, energise our team, and be part of something bigger. Your 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. NESO, 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 the trade-offs between them. The organisation is set up as a public corporation with its own Board of independent directors, with complete operational independence from government, the regulator and any and all commercial interest. As was the ESO, NESO will be licenced and regulated by Ofgem through price control agreements and obligated to identify optimal solutions to system operations and planning in the most sustainable, affordable and secure way for all. The time to deliver is now. As part of our team, you won’t just be touching the lives of almost everyone in Great Britain – you’ll be shaping the way we use and consume energy for generations to come.

Key Accountabilities

• Conduct the modelling and analysis required to develop regional whole energy supply & demand pathways across different vectors such as hydrogen, biomethane, electricity or specific sectors e.g. Industry, heat, transport, consumer as well as whole system modelling. This will involve working with cross-functional teams to agree assumptions and approaches, and then conducting the studies required.
• Lead development of forecasting approaches and consistent assumptions with energy experts across at least two sectors such as Industry, heat, transport, consumer or vectors such as hydrogen, biomethane.
• Develop new processes to create regional whole energy pathways from a wide range of local energy datasets, ensuring coherence with national plans and providing inputs into the RESP methodology.
• Lead engagement with external stakeholders through bi-laterals, technical working groups and workshops to inform your modelling, analysis and processes.
• Conduct energy industry research to stay abreast of emerging analysis & modelling techniques and assumptions, applying these to whole energy analysis.
• Build relationships with other NESO analysis/modelling teams and share best practice. Identify experts in specific types of studies and models and seek their advice to support complex projects.
• Provide guidance and training to other members within the team.

About You

• A wide understanding of the energy sector, with experience of energy (Supply/demand) planning especially at Distribution network level across at least one energy vector i.e. hydrogen, biomethane, electricity or sectors e.g. Industry, heat, transport, consumer or experience in whole system modelling.
• Analytical skills: Experience in analytical role(s) including the ability to think holistically across energy vectors to bring together a whole energy systems approach.
• Ability to undertake research using diverse sources, scope and prioritise which questions to answer and filter for important developments including reading publications and policy papers, attending conferences, meeting and interviewing key stakeholders across different sectors of the economy and keeping up to date with news on technological and social developments.
• Structured problem solver: You excel in structured problem solving, with a focus on data-related challenges and solutions.
• Communication: Experience of communicating with, and influencing, internal and external stakeholders. You can convey complex findings to non-technical stakeholders and translate data and analysis to inform decision making.
• A high level of computer literacy and are proficient in using analytical software packages (e.g., R, SQL, MatLab, Excel, VBA or Excel Solver).
• Confidence using large bespoke software / a high level of computer literacy (e.g. excellent Excel skills). You should also have experience using data science packages (e.g. SQL, Python, MatLab) or developing analysis tools.

About What You’ll Get

A competitive salary between £51,000 – £66,000 per annum – dependent on experience and capability. As well as your base salary, you will receive a bonus based on company performance, 26 days annual leave as standard and a competitive contributory pension scheme where we will double match your contribution to a maximum company contribution of 12%.
