Vattenfall and the Danish Energy Agency (DEA) have signed the final agreements for the Hesselø and Holmsland offshore wind projects, which will add at least 1.8 GW of capacity to Denmark’s offshore wind pipeline.
The agreements formalise Vattenfall’s selection as the winning bidder for the two projects in Denmark’s latest offshore wind tender in August 2026.
Hesselø, with a minimum planned capacity of 800 MW, will be located in the Kattegat, while Holmsland, formerly known as North Sea I Mid, will have a minimum capacity of 1 GW in the North Sea, near Hvide Sande.
The developer says the name change from North Sea I Mid to Holmsland reflects the project’s location off the Danish west coast.
Denmark launched the tender for the offshore wind sites in November 2025 after its previous offshore wind procurement failed to attract bids. The revised framework introduced state support through two-sided contracts for difference (CfDs), with Vattenfall submitting the lowest bids for both sites.
With the agreements signed, Vattenfall will continue developing the projects in cooperation with Danish authorities and other stakeholders, with an aim to commission the wind farms in 2032. However, construction remains subject to final investment decisions and the required approvals, the developer noted.
Vattenfall currently operates five offshore wind farms in Denmark, which together generate around 6.5 TWh of electricity annually. The company is also developing offshore wind projects in other European markets, including Nordlicht in Germany and Zeevonk in the Netherlands.
