Title:  Power System Engineer - 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.

Changes in the energy system over the last decade have resulted in system voltages and stability becoming increasingly challenging to manage. We have seen a continual decrease in minimum demand, reactive power consumption, system inertia and short circuit level. As we move to enable the zero-carbon operation of the system by 2025 and beyond, we need to ensure that we have all the services we need to be able to operate the system with only renewable sources of energy.

We are currently looking for x2 Power System Engineers. The role of this team is to determine the future system requirements, provide technical support to long-term Network Services tenders (previously known as pathfinders) to procure the services NESO will need, and drive changes to existing processes to test these new solutions. Whist doing this, we engage with various teams within NESO and with a wide range of industry stakeholders.

This role can be based from Wokingham, Warwick or 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

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 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.

Key Accountabilities

As a power system engineer within the Operability Product team, you will:

• Develop and undertake power system analysis to define system needs (e.g voltage, inertia, system strength).
• Prepare technical requirements and assessments for future Network Services tenders (voltage and stability pathfinders).
• Develop and maintain documentation for team processes.
• Contribute to the development of future voltage and stability markets.
• Contribute to the delivery of new operability products.
• Identify emerging and future system performance issues and operability challenges.
• Lead the development of new service products to ensure future system performance and operability.
• Provide support to other members of the team to carry out power system analysis.
