Delivering a cleaner, greener future
The construction of SEGL2 and its sister project, SEGL1, will create two High Voltage Direct Current (HVDC) electricity ‘superhighways’ from Scotland to England.
SEGL2 will run from Peterhead in Aberdeenshire to Drax in North Yorkshire, via the North Sea.
Both SEGL1 and SEGL2 are essential to meet the UK’s net zero commitments and deliver a cleaner, greener future.
What we propose to build
We are proposing to build and connect a new converter station at Drax, North Yorkshire. We also plan to install an underground cable from the coastline at Wilsthorpe, just south of Bridlington, to the new converter station and an existing substation at Drax.
We have applied for planning permission for the majority of the onshore cable from East Riding of Yorkshire Council.
The below plans are included in our planning application to Selby District Council and East Riding of Yorkshire Council and detail the key onshore elements of our project. You can explore our planning application via East Riding of Yorkshire Council’s planning portal, quoting the project reference number: 22/01990/STPLFE.
Selby District Council has yet to start its period of consultation. When it does, we will share details of where to view our planning application here.
Our converter station will house the technology to enable the green electricity to be transmitted through the approximately 505km cable.
A converter station converts electricity between Alternating Current (AC) and Direct Current (DC). AC is used in each country’s transmission system, while DC is used for sending electricity long distances along the subsea cables. Scottish and Southern Electricity Networks (SSEN) are developing proposals for the Scottish end of the link, which includes a new converter station in Peterhead.
Below is a plan that shows how we propose to lay out our converter station and integrate it into its surroundings.
This is an indicative image of what the converter station could look like.
The proposed cable route for SEGL2 runs under the North Sea for most of its 505km total length.
After travelling under the sea from Peterhead, it will come ashore at Wilsthorpe, just south of Bridlington. The cable will then run underground onshore for around 68km, to the new converter station and existing substation at Drax.
Please see the below image for a map of the route – from Wilsthorpe on the coast, to our new converter station at Drax.

Planning permission for the offshore section of the cable
The project has also submitted a marine licence application to the Marine Maritime Organisation for SEGL2’s approximately 437km submarine cable, the offshore element of the project.
Much like planning permission onshore, this process involves a period of technical appraisal and consultation which will inform the outcome of the application.
You can view our marine licence application on the public register by quoting the project reference number: MLA/2022/00273.

When will the work happen?
We have submitted our planning application for the onshore elements of SEGL2. If approved, construction is expected to be begin in 2024 and finish in 2029.
