Our response to coronavirus

Find out how we're working to keep the electricity and gas flowing reliably throughout the outbreak.

Delivering a cleaner, greener future

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

The construction of SEGL1 and its sister project, SEGL2, will create two electrical superhighways from Scotland to England. These proposed links are essential to meet the UK’s net zero commitments and deliver cleaner, greener future.

Where will the HVDC link be built?

If approved, SEGL1 will run from the Torness area in East Lothian to Hawthorn Pit (between Murton and South Hetton) in County Durham. 

It will travel most of its journey under the North Sea before coming on land just north of Seaham in County Durham. The cable link will then run underground for approximately 10km before connecting to the national grid network at Hawthorn Pit.

The below map shows the proposed route of the cable and the converter station and substation locations.

The red line shows the broad corridor that we identified for the cable route, and the area where we will conduct surveys. The black line indicates the preferred cable route. Please click on the map to see it in more detail.
