Sea Link (Suffolk–Kent)

In planning

A 138 km primarily offshore link is awaiting its development-consent decision, expected by 30 October 2026. Surveys and archaeological works have separate permissions. These preparatory activities do not establish consent for the main link, whose construction programme is conditional on approval.

What this link contributes

This asset provides a route for electricity to move between networks or strengthens the network carrying that electricity. Its capacity cannot be added to wind, solar or power-station capacity as though it were another generator.

Suffolk ↔ Kent

Converter stations, cable manufacture, offshore installation, landfall works and grid energisation can progress at different times. The status above describes the documented project stage rather than assuming all work packages are complete.

Project location

Connection sites and areas are shown separately. Dashed circles mark approximate endpoint areas. No straight line is presented as the cable or overhead-line route.

Markers identify sites, published points or labelled connection areas. Markers are not site boundaries or entrances. EGL2’s additional outlines and route layers are explicitly identified in the developer’s map data.
