The UK is committed to achieving net-zero greenhouse gas emissions by 2050, and as the country moves away from traditional fuel sources like coal and oil to heat homes and power vehicles and businesses, we will need more renewable power like green electricity.

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 plan 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 existing substation at Drax.

Converter station and substation

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.

Underground cable

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.

This image shows what the cable looks like.

Where we propose building SEGL2

If approved, SEGL2’s cable will make landfall at Wilsthorpe, south of Bridlington

The cable will then run underground for approximately 68km before connecting to the national grid network at Drax.

When will the work happen?

If approved, construction is expected to begin in 2024 and finish in 2029.

We held our public consultation in spring 2021.
