Suomen Hyötytuuli Oy has built the world’s first offshore windfarm designed for demanding ice conditions in Tahkoluoto, Pori, Finland. The wind farm produces energy since autumn 2017.

Tahkoluoto offshore wind farm in a nutshell

10 offshore wind turbines with a capacity of 4,2 MW each
Rotor hub height approx. 90 meters and the rotor diameter 130 meters
Average power production 43% of the maximum capacity
Estimated annual power production approx. 155 GWh
Steel shell structure undersea foundations
Substation on shore
Investment of approx. MEUR 120
Estimated direct effect on employment over 300 person-years

Conditions for the offshore wind power production are different compared with, for example, the North Sea, since the cold and icy conditions require special technical solutions. Tahkoluoto’s sea area in front of the port of Pori and the industrial area, the infrastructure, and the wind conditions are perfectly suited for the production of offshore wind power.

Tahkoluoto’s offshore wind farm project implements the climate and energy strategy, both on the European Union level and on the national level. The Ministry of Employment and the Economy has granted an investment aid of MEUR 20 for the project in order to boost business and export in Finland.
