Vattenfall has been awarded the Hesselø and North Sea I Mid offshore wind projects in Denmark’s latest offshore wind tender, expanding the company’s offshore portfolio and supporting the growth of fossil-free energy production in Europe.

The company said the award represents another step toward meeting rising demand for reliable, locally produced electricity.
“Winning both projects reflects our continued ambition to grow our offshore wind portfolio and support the electrification of industry and society,” said David Flood, Head of Business Unit Offshore at Vattenfall. “Wind power, together with other fossil-free sources of generation, can help meet the growing demand for clean electricity in Europe. Projects like this demonstrate how we are scaling offshore wind while maintaining a strong focus on affordability and long-term value.”
The Hesselø offshore wind project is located in the Kattegat Sea between Denmark and Sweden, around 30 kilometers from the coast. It will have a minimum installed capacity of 800 MW. The North Sea I Mid Offshore Wind Project is located in the North Sea, approximately 20 kilometers off the coast near Hvide Sande, with a minimum capacity of 1,000 MW.
Grid connection has been reserved for both projects, with the connection point located about 50 kilometers inland. Consent for the projects will be granted for 30 years, with an option to extend it by an additional 10 years.
The projects will add to Vattenfall’s existing offshore wind portfolio in Denmark, which totals around 1.5 GW. The company currently operates five offshore wind farms in Denmark, generating about 6.5 TWh of electricity annually, enough to supply approximately 1.5 million homes.
Vattenfall said the Hesselø and North Sea I Mid projects will be developed with attention to environmental and social considerations, while creating value for businesses, communities and the wider energy system.
The company will now work with relevant partners and authorities to further develop both offshore wind projects.
