to be operational


We’re currently developing a major wind farm in the municipality of Ii in North Ostrobothnia. Once completed, this will consist of approximately 50 to 75 turbines. This site is especially well-suited for wind power production, as it’s a vast, uninhabited forest area with huge wind potential.


We were granted the necessary permits for this project in 2019, and the wind farm will be operational in mid-2020s. Like in all our projects, we’ll be using the latest technology. In Ii, this means constructing 300-metre-high turbines, which is the maximum permitted height.

Asset management

Once the wind farm is operational, our sister company Ilmatar Service Oy will provide it high quality technical and commercial management.
