Linking Great Britain and France

The HVDC cables linking the electricity transmission systems of Great Britain and France are an essential part of IFA2. We’ll carry out the work to lay these cables in 2019.

The cables will be buried in the seabed. We’ll install the cables using large specialist vessels which are able to transport and lay long sections of cables (up to 100 km). Some cable joints will need to be made at sea during the installation process.

We have already worked closely with maritime stakeholders, including fishermen, Natural England, the Maritime and Coastguard Agency, Trinity House, the Royal Yachting Association, the Chamber of Shipping, Historic England and Portsmouth and Southampton harbourmasters to determine the most appropriate route for the cables.

We’ll continue to communicate with maritime stakeholder throughout the construction process to ensure they’re aware of work we’re doing to lay cables.
