Tahkoluoto offshore wind farm Extension project’s demo phase is granted water and building permits

Suomen Hyötytuuli is planning an Extension project to Tahkoluoto offshore wind farm on the western coast of Finland. Tahkoluoto offshore wind farm is the world’s first offshore wind farm in frozen sea conditions.

Tahkoluoto Extension offshore wind farm will be located 4–22 kilometres off the coast of Pori, in Western Finland. In the demonstration project phase, two wind turbines will be built to pilot new, large-scale offshore wind turbines and a foundation concept for deep waters in frozen sea conditions. The demonstration phase of the Extension project has now been granted water and building permits.

“This is the first time that permits have been granted for wind turbines of this scale in Finland. It was important for us to ensure that the detailed understanding of the marine life that we gathered during the environmental impact assessment and land use planning, have been taken into account in the permitting”, says Juho Lappalainen, Project Development Manager for Tahkoluoto Offshore Extension project. ”Naturally, we also have to monitor the environmental impacts comprehensively during the construction phase and the initial stages of production.”

”With the building and water permits in force, the investment decision is close at hand. Next, we will verify the pricing and availability of the critical components of the project, after which we are ready to proceed to the implementation phase”, says Manu Grönlund, Project Director of the Tahkoluoto Offshore Extension demonstration project.

The findings of the demonstration project will be applied to the Tahkoluoto Extension project, which consists of forty wind turbines of over 15 megawatts. The construction phase is planned for 2027–2029. The total capacity of the wind farm will be 600–800 MW.

The construction of the first turbines of the extension project has received funding from EU’s NextGenerationEU.
