The proposals to maximise the renewable energy potential of Scotland's largest offshore wind farm have been accepted by Scottish ministers, according to John Hill, the project director for Seagreen. The remaining 36 turbines in the project's plan will have an installed capacity of up to 500MW thanks to the Section 36C (S36C) proposal, which would have increased that number from 360MW. In addition, Seagreen will help Scotland achieve a net-zero carbon future because it can now capture more wind to generate more renewable energy, according to Hill.

A joint venture between SSE Renewables (49%) and TotalEnergies (51%), Seagreen is Scotland's largest offshore wind farm and one of the greatest private investments in Scottish infrastructure. The first 114 of the 150 offshore turbines, which have a grid link into Tealing, Angus, are being built, and the project generated its first power in August 2022. All 150 offshore turbines have received approval. National Grid decided to expand the project's grid connection offer at Cockenzie, East Lothian, to 500MW last year. Seagreen's S36C proposal is in response to that decision.

In order to modify the current consent and enhance the height and dimensions of Seagreen's remaining 36 turbines, Seagreen filed a Section 36C application to Marine Scotland in May 2022. East Lothian Council unanimously agreed the planning approval in principle (PPP) for the Cockenzie substation and onshore cable infrastructure in August 2021.
