Suomen Hyotytuuli has received water and building permits for its Tahkoluoto offshore wind farm extension project’s demo phase.
The Tahkoluoto Extension will be based 4km-22km off the coast of Pori, western Finland. The demonstration phase will add two new turbines to pilot new, large-scale offshore hardware and a foundation concept for deep waters in frozen sea conditions.
The findings of the scheme will be applied to the Tahkoluoto Extension project, which consists of 40 turbines of over 15MW. The construction phase is planned for 2027-2029. The total capacity of the wind farm will be 600MW–800MW.
“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,” said project development manager for Tahkoluoto Offshore Extension Juho Lappalainen.
“Naturally, we also have to monitor the environmental impacts comprehensively during the construction phase and the initial stages of production.”
Project director of the Tahkoluoto Offshore Extension demonstration scheme Manu Gronlund added: “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.”
