Ilmatar is developing two separate wind farms in Punkalaidun municipality: Isosuo and Arkkuinsuo. The planned areas have predominantly been in peat production use. High-quality wind conditions, distance to residential areas and compatibility with existing land use purposes make especially Isosuo a suitable area for wind power production.
A partial land use plan has been prepared for the Isosuo project and the plan was accepted by the municipality of Punkalaidun in 2015. The plan allows for constructing up to 6 wind turbines with tip heights up to 210m. The environmental impacts of the project have been assessed as part of the land use plan process.
The parallel use of the wind farm areas for example in recreational and berry picking purposes will be allowed also after the wind farm has been commissioned.
Ilmatar is currently not progressing the development of the Arkkuinsuo area but is focussed on Isosuo.
Isosuo is expected to enter construction phase during 2022 and is planned to start generating power by 2023-2024.
Ilmatar Service Oy, a subsidiary of Ilmatar Energy, will take over the wind farm’s technical and commercial management once the project has been commissioned.
Ilmatar has been developing the Isosuo and Arkkuinsuo wind farm projects in close collaboration with YIT Rakennys Oy in the past. Ilmatar has since acquired YIT’s share in the project companies and is currently the sole developer.
Ilmatar is progressing the Isosuo wind farm project towards construction phase through its project company, Punkalaitumen Tuulivoima Oy, which is domiciled in Punkalaidun.
The municipality of Punkalaidun has announced the legal validity of Isosuo’s partial land use plan in 2020. Currently, Ilmatar is progressing development for example by commencing wind measurements on site during 2020-2021.
