Vattenfall’s Vesterhav Syd offshore wind farm is now 100 percent complete. Every single turbine at the offshore windfarm Vesterhav Syd has now supplied the first power connected to the Danish power grid and is delivering fossil free energy to 170,000 households.
Location
The offshore wind farm, located close to the Sondervig coast, consists of 20 Siemens Gamesa 8.4 MW wind turbines and its sibling project, located west of the coast of Vejlbi, will have 21 turbines of the same type.
Timeline
Between July and September last year (2023), Vesterhav Syd’s 20 wind turbines were erected at the farm and Vattenfall delivered the farm’s first power on the 10th of November of the same year.
Since then, the turbines have been connected one by one to the national grid and now the wind farm is 100 % operational. The milestone is the culmination of almost seven years’ work on the offshore wind farm.
Mathilde Damsgaard, project director for Vesterhav Syd and Nord at Vattenfall, highlighted that they are always happy when they finish an offshore wind farm thereby contributing to fossil freedom. She further added that they allowed to be happier this time around since there is winter in Denmark and Northern Europe where fossil free and reliable electricity is of great importance.
Project Challenges
The wind turbine installation at Vesterhav Syd offshore wind farm started in July 2023 and was completed in September last year, however, Vattenfall needed to change its plan to connect the turbines to the grid immediately as the export cables initially could not be buried deep enough. The project also encountered tough weather conditions that slowed down the offshore construction progress.
Costs
With a historically low strike price of 475 Danish øre per kWh, Vattenfall won the tender for the Vesterhav Syd wind farm back in 2016.
The Danish Energy Agency approved the construction of the two projects in December 2020 and granted Vattenfall an electricity production permit for the 344 MW Vesterhav duo in Summer 2023.
Vattenfall’s investment in North Sea North and North South is expected to be around EUR 740 million.
Twin project
Approximately 80 km away from its southern twin Vattenfall is also in the final stages of finishing the 176 MW Vesterhav Nord offshore wind farm and expects to connect it to the grid in this years’ first quarter.
The combined capacity of Vesterhav Syd (168 MW) and Vesterhav Nord (176 MW) is 344 MW which will be able to power more than 350,000 Danish households.
With a capacity of 8.4 MW each, the offshore wind farms will consist of 20 and 21 turbines respectively.
