Vattenfall and the Danish Energy Agency have signed the final agreements for the Hesselø and Holmsland offshore wind projects. The two projects were awarded to the utility in Denmark's latest offshore wind tender in August 2026. The documents were signed by Anne Mette Traberg, Country Manager Denmark at Vattenfall, and Adrian Lübbert, Director General of the Agency. According to Vattenfall, the step marks the next phase in the development of two future Danish offshore wind farms.

Two projects totalling at least 1.8 GW

Hesselø has a minimum capacity of 800 MW and is located in the Kattegat. Holmsland, with a minimum capacity of 1,000 MW, will be sited in the North Sea near Hvide Sande. The wind sector is also seeing other developments, including OX2's reduction in the number of turbines at the Dinner Hill wind farm in Western Australia and the 108 MW order secured by Vayona Energy from Continuum Green Energy. Together, Hesselø and Holmsland will add at least 1.8 GW of offshore wind capacity to Denmark's energy system.

As part of the agreement, the North Sea I Mid project is renamed Holmsland. The name reflects the project's location off the coast of Holmsland and was chosen to give it a more recognisable designation, Vattenfall says. Both wind farms are due to be operational by 2032, according to the company, which presents the capacity as support for growing electricity demand and the country's climate ambitions.

An established presence in Denmark and Europe

Vattenfall says it operates five offshore wind farms in Denmark, generating around 6.5 TWh (terawatt-hours) of fossil-free electricity annually. The group also states that its offshore portfolio spans six markets, with projects ranging from development to delivery and operation.

"As we deliver Nordlicht in Germany, progress Zeevonk in the Netherlands, and take the next steps with Hesselø and Holmsland in Denmark, we continue to build on our offshore wind experience and expertise across markets," says Anne Mette Traberg. She adds that the focus remains on delivering competitive projects with discipline, creating long-term value and continuing to build momentum towards fossil freedom.

Investment decisions still to come

Following the signing, Vattenfall will continue developing both projects in close cooperation with authorities and stakeholders. Any decision to construct Hesselø and Holmsland remains subject to final investment decisions and relevant approvals, the company states. The two wind farms have a combined minimum capacity of 1.8 GW, with commissioning expected in 2032.
