OstSee Energies is a 1 GW offshore wind project located on the Federal Maritime and Hydrographic Agency (BSH) concession O-2.2 in the German Baltic Sea, roughly 40 km off the coast near Rügen. Awarded to TotalEnergies in the 2023 German offshore tender, the site was allocated with a bid price ben...

TotalEnergies submitted a planning approval application for the 1 GW OstSee Energies (OSE) offshore wind farm on site O-2.2 in the German Baltic Sea to the Federal Maritime and Hydrographic Agency (BSH). The application, made under the German Offshore Wind Energy Act, covers the overall project development and includes the protection and safety concept and a preliminary layout for turbine and cable arrangement within the site.
In October 2024, during the announcement of new names for its German offshore wind portfolio, TotalEnergies confirmed that geophysical survey activities for the OstSee Energies (OSE) offshore wind project had commenced. The 1 GW project, located on concession O-2.2 around 40 km from the German Baltic Sea coast, will undertake environmental surveys jointly with neighbouring wind farm developers. The article states that the geophysical and geotechnical campaigns and associated technical studies have started, indicating that seabed and subsurface mapping and related investigations for OstSee Energies are underway to inform detailed design and development of the project.

In October 2024, TotalEnergies commenced geotechnical survey activities for the OstSee Energies (OSE) offshore wind project, located on the 1 GW concession O-2.2 around 40 km from the German coast in the Baltic Sea. The article notes that for OSE, the geophysical and geotechnical campaigns, along with associated technical studies, have started. These campaigns form part of the broader environmental and site investigation programme, which is being coordinated jointly with neighbouring wind farm developers, mirroring the collaborative approach used at TotalEnergies’ North Sea sites. The start of the geotechnical campaign marks a key early development milestone, providing essential seabed and soil data to support detailed design and engineering for the project’s foundations and other offshore infrastructure.
On 14 October 2024, TotalEnergies publicly announced that its 1 GW offshore wind project on German concession O-2.2 in the Baltic Sea will be developed under the new name OstSee Energies (OSE). In the same announcement, the company confirmed the site’s location around 40 kilometres from the coast and outlined its development concept within its German offshore portfolio, including joint environmental surveys with neighbouring projects and ongoing geophysical, geotechnical and technical studies, ahead of a targeted final investment decision in 2028 and first power generation in 2031.
In July 2023, TotalEnergies was awarded the 1 GW O-2.2 offshore wind concession in the German Baltic Sea, located around 40 kilometres from the coast, which it will develop as the OstSee Energies (OSE) project under a tender run by the Federal Network Agency.
