The National Energy System Operator (NESO) and the UK’s main transmission networks and interconnectors have finalised a new working agreement with the European Network of Transmission System Operators (ENTSO-e), bolstering intracontinental cooperation on electricity.
UK TSOs were unable to remain as participating members of ENTSO-e after Brexit, with the exception of the System Operator for Northern Ireland (SONI). However, the post-Brexit Trade and Cooperation Agreement recognised the mutual benefit of continued cooperation in energy matters, which today’s working agreement fulfils.
The new deal follows similar working arrangements between the UK’s gas transmission operators and the European Network of Transmission System Operators for Gas (ENTSOG) and between Ofgem and the EU Agency for the Cooperation of Energy Regulators (ACER).  
Fintan Slye, Chief Executive Officer, NESO, said: “We warmly welcome these new working arrangements between Great Britain and EU energy networks, recognising the importance of collaboration across our various organisations to strengthen energy security and clean power.
“We look forward to working closely with ENTSO-e in future to represent the views of our colleagues across the UK’s electricity networks sector.”  
NESO will represent British transmission network operators at coordination meetings with ENTSO-e.
The European Network of Transmission System Operators for Electricity (ENTSO-E) is an association representing 40 electricity transmission system operators from 36 countries across Europe. Meanwhile eight European Transmission System Operators (TSOs) have formed an Innovation Alliance to accelerate innovation that improves the resilience and efficiency of the European electricity grid. Its first area of work will be weather and grid resilience.
