The Danish Energy Agency has suspended the Hesselø Offshore Wind Farm after the result of the preliminary site investigations.
The investigations revealed soft clay formations in the upper 20-30 meters below the seabed in large parts of the selected location for Hesselø OWF. This indicates less favorable site conditions than initially specified in the fine screening report, and this must be analyzed further. The further process of the tender depends on the result of the additional analyses which are expected to be completed in the autumn of 2021.
The site of the Hesselø Offshore Wind Farm (OWF) is located north of the island Sealand in Kattegat, in Hesselø Bay, at a distance of 30 km from Sealand and around 20 km from the small island Hesselø. The site is an area of approximately 247 km2. The Hesselø OWF will have an installed capacity of around 800-1,200 MW and be able to deliver up to 1,000 MW to the Danish electricity grid.
Hesselø Offshore Wind Farm comprises facilities and installations offshore as well on land. The offshore site will consist of a wind park with wind turbines, transformer platforms with high-voltage electricity substations, and electricity cables. The offshore wind farm will be connected to the existing high-voltage electricity network at the Hovegård high-voltage electricity substation, west of the town of Ballerup, through electricity cables and high-voltage electricity substations placed on the land. The facilities offshore and on land must be established by the winning tenderer.
Based on the results, the DEA expects to send a new invitation to market dialogue and thereafter to decide on the further process for the tender.
The Danish Energy Agency has selected Sweco as a technical advisor in the preparatory work to offer the task of constructing the world's first energy island in the North sea.
