Electricity interconnection between France and the UK: update
Share the page
France and the UK have worked in partnership on electricity interconnection projects since 1986.
CRE, the French Energy Regulatory Commission, and Ofgem, Great Britain’s (England, Scotland and Wales) independent energy regulator, regularly assess the opportunity for new interconnection capacity. For example, by estimating the costs and benefits that could be expected from these types of projects.
Agreed approach
CRE and Ofgem have agreed to continue exploring further interconnection development opportunities of around 1 Gigawatt (GW) capacity between France and the UK.
CRE and Ofgem aim to publish an updated joint statement in November 2025.
