Title:  Data Scientist/Analyst - NESO

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 UK has committed to reaching net zero by 2050, and the energy industry is transforming to meet that goal. The National Energy System Operator (NESO) has been given a new and exciting responsibility: acting as the Regional Energy Strategic Planner (RESP) for Great Britain. RESP will coordinate the development of the distribution energy system, enabling confident, long-term investment that supports a whole-system, place-based approach to decarbonisation.

The National Energy System Operator (NESO) is recruiting Data professionals to join the RESP Digital and Data team. These roles are critical to enabling the creation of RESP products by applying data expertise directly within multidisciplinary squads. These roles will be key parts of the Data Community to ensure data is robust, usable, and impactful.

This role can be based from Warwick or Wokingham, 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

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 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
