Ten years of development
In 2010, the Crown Estate awarded Seagreen Wind Energy Limited (now a joint venture between TotalEnergies (51%) and SSE Renewables (49%)) was awarded the exclusive development rights for the Firth of Forth Zone of the UK's Round 3 offshore wind farm development programme. The Zone, located over 27km from the Angus coastline, covers an area of around 3,091 Km2 in the outer Firth of Forth.
Seagreen Wind Energy Ltd (SWEL) has worked closely with stakeholders and undertaken extensive surveys and assessments to develop the Seagreen offshore wind farm. 114 turbines are currently under construction with a 1,075MW installed capacity.
The original Seagreen consent provided for up to 150 turbines. SWEL is progressing plans for the connection of the remaining 36 turbines which is known as the Seagreen1A project. You can find out more about the Seagreen 1A project by clicking here.
Separately, SSE Renewables is developing proposals for an additional wind farm within the Firth of Forth Zone. You can find out more about the proposals for the Berwick Bank offshore wind farm by clicking here.
Sensitively located
The location and layout of the Seagreen offshore wind farm has included extensive assessment taking into account the potential impacts on marine wildlife, bird populations and landscape and visual.

This map shows the export cable route for the first phase of 114 turbines from Seagreen to the Tealing substation.
For more information about the connection for the remaining 36 turbines into Cockenzie, East Lothian, please click here.
In both cases the electricity generated by Seagreen will be transmitted to the substations via subsea and underground cables.
