GLASGOW, UK  SSE Renewables says all 114 Vestas V164-10 MW turbines at the 1.1-GW Seagreen wind farm offshore east-central Scotland are now fully operational and sending power to the UK grid.

Seagreen, 27 km from the Angus coast in the Firth of Forth, is Scotland’s largest operational wind farm and the deepest fixed-bottom offshore wind development, the company added, with the deepest foundation installed 58.7 m below sea level.

The facilities are controlled from an operations and maintenance base at Montrose Port.

Seagreen, a joint venture between TotalEnergies (51%) and SSE Renewables (49%), first attained exclusive development rights for the Firth of Forth Zone site from Crown Estate Scotland in 2010. In 2014 the Scottish government approved the development with construction starting in June 2020.

The first Vestas 10-MW turbine was installed in December 2021, and first power followed in August 2022 with the final turbine set down at the site earlier this summer.

Power from the 114 turbines is exported via three subsea cables to landfall at Carnoustie, and then through 19 km of underground cabling to the new onshore substation at Tealing near Dundee, before entering the grid.

SSE Renewables led the development and construction, and it will operate the offshore wind farm over its 25-year lifespan with support from TotalEnergies.

TotalEnergies said it would commercialize its share of production via a mix of a long-term contract at guaranteed price, including a 15-year CfD (contract for difference) awarded by the UK government; a 15-year private CfD with the SSE Group; and short-term sales on the wholesale market.

Seagreen is also now the company’s largest operating offshore wind farm worldwide.
