TotalEnergies, as a shareholder of North Sea OFW One GmbH, has been awarded the N-9.4 offshore concession by the Federal Network Agency. Located in the North Sea, approx. 150 kms northwest of the German island of Heligoland, the N-9.4 concession covers an area of around 141 sq kms and will enable the development of 1GW of offshore wind capacity. The concession is granted for a period of 25 years, extendable to 35 years.
This N-9.4 concession is located in very close proximity to the N-9.1 and N-9.2 sites, jointly owned by RWE and TotalEnergies, TotalEnergies’ intending to prioritize the development of this cluster and leverage synergies to optimize construction and operating costs for the benefit of its customers.
As part of this award, Offshore Wind One GmbH will pay €18 million to the German federal government in 2026, which will be allocated to marine conservation and the promotion of environmentally friendly fishing practices. In addition, an annual contribution of €8.1 million will be paid for 20 years to the electricity transmission system operator responsible for connecting the project, starting from the commissioning of the site.
Furthermore, considering the longer delays in the connection timelines announced by the German transmission system operators (TSOs), TotalEnergies has launched a strategic review of the various concessions obtained since 2023, with a view to engaging in dialogue with the German authorities to explore the conditions of their possible developments.
