Job Function:  Engineering

Job Purpose

Great Britain's electricity system is undergoing an ambitious, exciting and vital transformation. Together with industry, we are creating a cleaner, greener system, one that protects the planet and serves generations to come.  


We are looking for an Economic Assessment Manager to join our SND team. Strategic Network Development (ND) is accountable for leading the development of an economic and efficient Electricity Transmission network across Great Britain, Offshore and Europe meeting the requirements of customers, and in developing our development processes so they enable GB to meet our Net Zero targets. 


The purpose of this role is to lead and manage economic assessments of electricity network developments within the Strategic Energy Planning directorate, contributing towards exceptional analysis in all our reports.


This role can be based from Wokingham or 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

As Great Britain’s electricity system operator (ESO), we sit at the heart of the electricity system, using our outstanding engineering and commercial expertise to balance electricity supply and demand. Ultimately, we keep the electricity flowing directly to where it’s needed, second by second.


Becoming the National Energy System Operator

In Summer of 2024, the ESO will transition to becoming the National Energy System Operator, or NESO for short. Previously denoted as the Future System Operator (or FSO), the new National Energy System Operator will be 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, will be 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 will be 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 the ESO are today, 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.
