Title:  HV Submarine Transmission Cable Specialist - NESO

About the role

National Energy System Operator’s (NESO) strength lies in our people. Together, we’re shaping the future where clean, affordable energy is accessible for all. Every day is an opportunity to make a real difference, accelerating the progress of sustainable GB energy, keeping people connected and society thriving as we create a brighter tomorrow.

As the NESO prepares for the introduction of competition within GB’s transmission system, the network competition team has a vacancy for a HV Submarine Transmission Cable Specialist.

The HV Submarine Transmission Cable Specialist will provide specialist advice and knowledge to the NESO around the deliverability of submarine cable projects. The primary role will be to assess the suitability of "wet onshore" transmission links for Early Competition within NESO and prepare technical information for tenders. In addition, the specialist will help the NESO develop its capability in understanding the delivery risks and challenges associated with submarine transmission assets and may therefore be involved in other aspects of NESO directorates, such as network planning and offshore coordination.

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.
