The company has also successfully opened the Vesterhav North and South offshore wind farms in Denmark in autumn 2024, marking a significant milestone in their renewable energy initiatives (source: group.vattenfall.com). While no specific new contracts or acquisitions were reported for 2023-2024, Vattenfall continues to focus on its operational milestones and ongoing developments in offshore wind energy.
