National Grid has applied for development consent for Sea Link, a new electricity connection between Kent and Suffolk in England.
The aim of the project is to boost energy security and deliver cleaner energy to strengthen Great Britain’s network.
As part of The Great Grid Upgrade, the Sea Link project is designed to increase electricity capacity, as demand for energy is set to double, ensuring more renewable and low-carbon power reaches homes, business and public services.
The proposed 138km connection, from Pegwell Bay in Kent to a point on the Suffolk coast between Aldeburgh and Thorpeness, will run mostly offshore.
Around 122km of the cables will be located under the sea with underground cables then linking to converter stations so electricity can be transported to where it is needed in East Anglia, Kent, and the rest of the country.
National Grid has submitted the application for development consent to the Planning Inspectorate.
Sea Link project director Adrian Pierssene said: “We have listened to and considered all the feedback we have received, shaping the plans we are submitting as a result.
“Sea Link is a vital investment in Great Britain’s energy future, creating the extra capacity needed to integrate renewable power into the grid, boosting energy security and supporting a cleaner electricity network.”
National Grid developed plans for the project following multiple rounds of public consultation between 2022 and 2025.
The application will now be considered through the Nationally Significant Infrastructure Project (NSIP) planning process led by the Planning Inspectorate.
The public will have further opportunities to provide input during the examination stage.
