Finnish Developer Probing Seabed at Extension Site of World’s First Offshore Wind Farm in Freezing Conditions

The construction of the extension offshore wind farm is expected to take place in 2027–2029, with the wind farm’s total capacity planned to be between 600 MW and 800 MW.

The two-turbine demonstration project, which will put the larger-scale offshore wind turbines to the test in freezing conditions , will be built first.

The pilot project will also demonstrate a foundation concept for deep waters in frozen sea conditions, significantly deeper seabed installations and seabed building methods appropriate for these conditions, according to the developer.

The demonstration project was granted building and water permits in December 2023.

The European Union has granted the demonstration project funding under the NextGenerationEU recovery instrument, according to Suomen Hyötytuuli.

The Finnish developer said this March it would conduct a full demerger that would see its wind farms, including the existing Tahkoluoto offshore wind farm, transferred to a new firm of the same name, while Tahkoluoto Offshore Oy would take ownership of the new Tahkoluoto demonstration and extension project.

The demerger process, initiated with the filing of the plan with the Finnish Patent and Registration Office on 8 March, is scheduled to be completed by the end of summer 2024.
