We are becoming a separate company

In April 2019, the Electricity System Operator is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Our new legally separate company

From 1 April 2019 the Electricity System Operator will become legally separate from National Grid Electricity Transmission (NGET) – but remain a valued part of the National Grid Group – in a move backed by BEIS and Ofgem.

The role and the form of the ESO will adapt to keep pace with an ever-changing system. It is an opportunity for us to keep consumers' household bills down by working to ensure and enable more competition, coordination, and innovation across the system. 

The ESO role includes balancing the electricity grid second by second. As the electricity system becomes more flexible this role will need to evolve. The ESO will need to work more closely with local electricity distribution network operators (DNOs) to manage electricity flows across the grids.

What you need to know

  • National Grid Electricity System Operator (NGESO) will start operating as a separate company, within the National Grid Group, from 1 April 2019. 
  • To make sure we get legal separation right, we commenced separation activities across the ESO and Electricity Transmission (ET) in autumn 2018. This means you have already started to see the ESO and ET acting as separate entities ahead of the April 2019 go-live date. 
  • NGESO will continue to align to National Grid’s purpose, vision, and values, but has its own visual identity with a new brand, identity and website. 
  • Our support functions will continue to provide their services to all businesses within the National Grid Group through a business partner model that maintains existing efficiencies. 
  • Warwick-based NGESO employees are now based in a separate building from other National Grid companies called Faraday House. Faraday House now has a separate entrance and facilities for NGESO. 
  • Wokingham-based NGESO colleagues are already physically separate from other employees and will, therefore, remain in their current location.

As we have worked towards separating the Electricity System Operator, we have tried to put your experience as a customer at the heart of our thinking. If you do have any questions, please do not hesitate to contact [email protected].
