Ilmatar is currently preparing a wind farm in the municipality of Ii in Northern Ostrobothnia, Finland. The planning area of Ollinkorpi is located northeast of Northern Ii. The Ollinkorpi project started as a broad concept and has been refined over time through the zoning process. The Municipal Council of Ii approved the detailed zoning plan for Ollinkorpi, which includes 10 wind turbines, on May 2, 2022.

The combined Environmental Impact Assessment (EIA) and wind power zoning process began in 2019. The detailed zoning plan was approved on October 31, 2022, and construction permits were granted on April 24, 2023. Currently, we are preparing for the construction phase, which is expected to commence no earlier than the end of 2024.

Upon completion, the high-quality technical and commercial management of the wind farm will be handled by Ilmatar’s sister company, Ilmatar Service Oy.
