IJmuiden Ver Beta Offshore Wind Farm

11 Jun 2024: Zeevonk II (a joint venture between Vattenfall and Copenhagen Infrastructure Partners (CIP)) was ranked highest in the assessment of IJmuiden Ver Beta. In its application, Zeevonk II has maximally guaranteed the certainty of realisation of the wind farm and the wind farm's contribution to the energy supply. Both Zeevonk II and its supply chain participate in the IRBC Agreement for Renewable Energy. No later than 18 months after the permit becomes irrevocable, Zeevonk II will provide maximum transparency about raw material consumption, environmental impact and value retention of the offshore wind farm. Zeevonk II has made a financial offer of €20 million per year, which Zeevonk II will pay annually for the entire 40-year permit period. In addition, the costs of environmental impact assessments and site characterisation studies, amounting to approximately €20 million, will be borne by the party awarded the permit. Measures that contribute to the integration of the wind farm into the energy system carried the most weight in the assessment. This was also reflected in the application of Zeevonk II. Zeevonk II focuses on the energy system of the future by realising new technologies on a large scale. For example, Zeevonk II will build an electrolyser with a capacity of 1 GW in the port of Rotterdam. Because the electricity from the wind farm comes ashore on the Maasvlakte and the electrolyser is built nearby, a large part of the electricity will not have to enter the electricity grid first. This will prevent additional load on the electricity grid. The green hydrogen produced will contribute to making our industry and transport more sustainable. Zeevonk II will also build an offshore solar park with a capacity of 50 MWp within the wind farm. This solar park will contribute to more efficient use of the offshore electricity transmission cable.
