Power System Engineer - NESO in Glasgow

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.

As a Power Systems Engineer in the Connection Operability Assessment teams, you will work in partnership with network owners and customers as part of the connections process to develop efficient connection solutions that meet both the customer needs and the technical standards (SQSS and Grid Code). We facilitate the connection of generation and demand onto the system, enabling the UK to meet its net zero system operation ambition whilst ensuring the network remains safe.

This role we continue to offer hybrid work, although you need to live within an hours commute of Glasgow as it’s a minimum requirement of one day per week on-site in Glasgow along with the flexibility to accommodate additional days on-site as determined by the needs of the business (up to five days per week, with as much notice as possible).

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.

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

• Undertake Power System modelling and analysis to verify the impact of customer connections onto the transmission network and/or to explore alternative connection solutions for the benefit of customers.
• Collaborate with Transmission Owners to ensure the designs for new connections are compliant with the SQSS requirements.

• Support customers in the specification of scenarios required for bespoke technical assessments e.g., SSCI/ SSTI and reviewing technical reports to ensure that technical performance is adequate.
• Support the customer contract managers and compliance managers with addressing technical queries from customers throughout the connections process.
• Support other departments within ESO on technical queries relating to the connections process.
