National Grid has submitted its development consent application for Sea Link, a new 138km (85mile) electricity connection between Kent and Suffolk.
Part of The Great Grid Upgrade, this project will enhance energy security and support the transition to cleaner power.
With energy demand set to double, Sea Link will increase capacity, ensuring more renewable electricity reaches homes and businesses. The connection will run mostly offshore, with 122km of cables under the sea and underground sections linking to converter stations.
This vital infrastructure will help transport low-carbon energy efficiently across East Anglia, Kent and the UK, strengthening the national grid.
Adrian Pierssene, Project Director for Sea Link 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.”
Following multiple rounds of public consultation between 2022 and 2025, National Grid has developed plans for the project, considering valuable feedback from communities and stakeholders in Suffolk and Kent.
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.
