Whole Energy Systems Model Development Manager
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.
The National Energy System Operator (NESO) has been given an exciting new role of Regional Energy Strategic Planner. We will be responsible for developing Regional Energy Strategic Plans (RESPs) for 11 nations and regions across Great Britain, empowered through recent Ofgem decisions and consultations. These RESPs will consist of four digital-enabled products: Nations and Regions Context, Strategic Investment Needs, National and Regional Pathways and Consistent Planning Assumptions (CPAs), and Spatial Context. The national and regional RESP teams will be supported by a Hub team providing strategic support, interfacing with national stakeholders and governance and providing services that are common to nations and regions and more effectively delivered centrally.
The purpose of this role is to create and lead a RESP Whole Energy Model Development Team. You will be accountable for owning the whole energy models and modelling capabilities that underpin RESP delivery, driving continuous improvement and best practice. You will be developing and maintaining models to inform RESP Pathways and Consistent Planning Assumptions (CPAs) development and responsible for developing and maintaining the models underpinning RESP whole energy system optimisation. You will work closely with the Pathways & CPAs team, running the models into this team and providing resources and capabilities to them.
You will manage a small, agile team but will be responsible for leading the relationship with external organisations involved in model delivery. You will also ensure that RESP’s approach is consistent with SEP and wider NESO approaches, including consistency with other NESO whole systems modelling capabilities.
This role can be based from Wokingham, Warwick, Glasgow, 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.
