Proposals to connect Scotland's largest offshore wind farm

Seagreen - Scotland’s largest offshore wind farm - is a development being taken forward by Seagreen Wind Energy Ltd (SWEL) which is owned by SSE Renewables and TotalEnergies.

The Seagreen project, 27km off the Angus coastline and 66km off the East Lothian coastline, will be able to generate 1.5GW from 150 wind turbines. It will provide enough clean, renewable energy each year to power up to 1.3 million homes.  The amount of carbon dioxide it will remove is similar to removing almost a third of all of Scotland's annual car emissions.  We have a dedicated project website for Seagreen and further information can be found at: www.seagreenwindenergy.com.

114 of the 150 consented turbines have a grid connection into Tealing, Angus, and construction on this grid connection started earlier in 2020.

The Seagreen 1A project website concerns the connection of the remaining 36 consented turbines.  An application was made to National Grid in October 2019 for a grid connection and National Grid responded with an offer to connect into the existing ScottishPower substation at Cockenzie in East Lothian which was accepted.  Our Seagreen 1A plans consist of an offshore cable corridor from the offshore wind farm to Cockenzie and proposals for landfall, the onshore cable corridor and the onshore substation.

In August 2021, planning permission in principle (PPP) for the Seagreen 1A substation and onshore cable infrastructure at Cockenzie was unanimously approved by East Lothian Council.

In December 2021, Scottish Government Ministers consented the Marine Licence application. The Marine Licence covers the offshore elements of the project, including an export cable approximately 110km in length, to connect the project to the grid at Cockenzie.

We have created this website to provide a way for the public to easily access information and find out how to contact us on our proposals.

 

Green corridor is the offshore lease area that Seagreen has applied to Crown Estate Scotland for Seagreen 1A proposals.  National Grid has provided a grid connection at Cockenzie.

Scottish Government Ministers consented the Marine Licence application in December 2021. 

Redline boundary of the onshore application site consented in August 2021 – the site is located in the Energy Zone of the Cockenzie site. The proposed onshore electricity transmission infrastructure at Cockenzie will comprise underground electricity cables, a new substation and associated temporary and permanent ancillary works.
