First Power at Scotland’s largest offshore wind farm

SSE Renewables and its partner TotalEnergies has announced first power generation from the Seagreen offshore wind farm, 27km off the coast of Angus in Scotland. As of Tuesday afternoon, four Vestas turbine, of a total of 114, have been commissioned and connected to the grid.

Seagreen will be Scotland’s largest offshore wind farm and the world’s deepest fixed bottom wind farm, with its deepest foundation due to be installed at 59 metres below sea level. When fully operational, the site will produce around 5 terawatt hours (TWh) of renewable electricity per year, enough to power the equivalent of 1.6 million households.

In 2020, Petrofac was awarded the contract to provide the engineering, procurement, fabrication, transportation, offshore installation, and commissioning of the High Voltage Alternating Current (HVAC) offshore substation platform, including the topside, jacket, and piles. An onshore substation at Tealing, near Dundee, including all civil work and major equipment, is also within our scope.

The 1,075 MW wind farm is expected to be fully operational in the first half of 2023.
