Vattenfall and the Danish Energy Agency have signed the final agreements for the offshore wind projects Hesselø and Holmsland, marking the next step in the development of two of Denmark's future offshore wind farms. The signing was announced by Vattenfall.

The agreements were signed by Anne Mette Traberg, Country Manager Denmark at Vattenfall, and Adrian Lübbert, Director General of the Danish Energy Agency. The projects were awarded to Vattenfall in Denmark's latest offshore wind tender in August 2026.

North Sea I Mid Renamed Holmsland

As part of the agreement, the project previously known as North Sea I Mid will be renamed Holmsland. According to Vattenfall, the name change reflects the project's location off the coast of Holmsland and was agreed upon to give the project a more recognizable name.

Project Scope and Timeline

The Hesselø project will have a minimum capacity of 800 MW and is located in the Kattegat. Holmsland will have a minimum capacity of 1,000 MW and is located in the North Sea near Hvide Sande. Together, the two projects will add at least 1.8 GW of offshore wind capacity to Denmark's energy system.

Both projects are expected to be operational by 2032. According to Vattenfall, the added capacity will support growing electricity demand and the country's long-term climate ambitions.

Development Continues after Signing

Following the signing, Vattenfall will continue the development of both projects in close cooperation with authorities and stakeholders. The company states that any future decision to construct the projects remains subject to final investment decisions and relevant approvals.

Building on an Established Danish Position

Vattenfall says the projects build on its existing offshore wind position in Denmark, where the company operates five offshore wind farms generating around 6.5 TWh of fossil-free electricity annually.

This is complemented by the company's offshore wind experience across Europe, with a portfolio spanning six markets and 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. Our focus remains clear: delivering competitive projects with discipline, creating long-term value, and continuing to build momentum towards fossil freedom," says Anne Mette Traberg, Country Manager Denmark at Vattenfall.
