National Grid is sharing its latest update on proposals for Sea Link, a new electricity infrastructure project between Suffolk and Kent. Sea Link is needed to carry renewable and low-carbon power from offshore wind, interconnectors, and nuclear power to where it is needed. 

The proposals include a new, primarily offshore, 138 km cable connection from Pegwell Bay in Kent to a point on the Suffolk Coast between Aldeburgh and Thorpeness. Plans include the onshore infrastructure needed at either end, such as onshore cables, converter stations and substations, and overhead line connections to connect the power into the existing network so it can be transported to homes and businesses nationwide.

National Grid’s statutory consultation in 2023 was an opportunity for local communities to see how the plans had developed following the first public consultation and to provide further feedback on the proposals. Since then, a number of changes have been made across different elements of the proposals, such as confirming preferred access routes, construction methods and compounds, refining the cable route corridor and more. National Grid is sharing these changes with communities before submitting an application for development consent to the Planning Inspectorate early next year.

Members of the public can provide feedback on the changes, or on the proposals more generally, by writing to the team between 8 July and 11 August 2024. 

Adrian Pierssene, Project Director for Sea Link, commented: “This reinforcement between Suffolk and Kent is essential in the UK’s journey to net zero by 2050 and is part of a wider programme to upgrade the entire network. We look forward to sharing the latest update on Sea Link with members of the public before we prepare our application for development consent.”
