Latest update
On 5 May 2026, the Planning Inspectorate (PINS) concluded its 6 month Examination of our development consent order (DCO) application.
Since 5 November 2025, multiple rounds of hearings and written submission deadlines have taken place at which those interested could attend and give their views. Thank you to everyone who took the time to participate in the Examination.
PINS will now prepare and submit a Recommendation report to the Secretary of State for Energy Security and Net Zero, who will make a decision on our application in November 2026.
For more information about our application or the Examination process, please see the dedicated Sea Link page on the Planning Inspectorate website.
Latest update
On 8 May 2026, we submitted a Town and Country Planning Act (TCPA) application to Thanet District Council for archaeology excavation works in Kent on our proposed converter station site. We discussed this work with the County Archaeologist and Historic England before submitting our application.
If approved, this would allow us to carry out the excavations from mid to late summer 2026, when the weather conditions are most suitable. This will minimise the time needed to complete the works, and help to minimise any potential local disruption.
We would deliver outreach activities as part of this work, with organisations such as local schools, universities, and archaeological interest groups. These activities could include producing educational resources and holding talks with students, site visits, and volunteering opportunities, where appropriate. We will share more information about any opportunities with relevant local schools, universities, and interest groups closer to the time.
Should our TCPA application be approved, works would commence in mid to late summer 2026. In the meantime, you can view the full planning application on Thanet District Council's website here.
About Sea Link
Sea Link is a proposed new 138 km primarily offshore high voltage electricity link between Kent and Suffolk.
Sea Link is a key part of The Great Grid Upgrade, the largest overhaul of the electricity grid in generations. It will help provide homes and businesses with secure, cleaner, home-grown British energy from more affordable sources.
With demand for energy set to double by 2050, Sea Link will carry energy between Kent and Suffolk in either direction to where it is needed, whilst avoiding existing bottlenecks on the network around London.
Why we need to build Sea Link
The existing electricity network in both Kent and Suffolk needs upgrading. This is because the UK’s electricity grid was originally built in the 1960s to connect electricity generated in power stations from fossil fuels, such as coal, from the North and Midlands of England and South Wales.
As the UK moves away from fossil fuels and increases clean energy generation, which is largely offshore, we need to connect electricity in new places.
Demand for electricity is also expected to increase by 50% by 2035, and double by 2050, as we decarbonise the energy that’s used for things like heating and transport.
Therefore, significant new infrastructure is needed to connect this clean energy from where it’s now generated to homes and businesses.
