Estimated commissioning


Ilmatar is currently preparing a wind farm in the municipality of Ii, located in Northern Ostrobothnia, Finland. The Ollinkorpi planning area is situated northeast of Northern Ii. The Ollinkorpi project began on a broad scale and has since been refined through the zoning process over time.

The combined Environmental Impact Assessment (EIA) and wind power partial master planning began in 2019, and the partial master plan was approved on October 31, 2022. Building permits were approved on April 24, 2023. Currently, preparations are underway for the construction phase, which is expected to start no earlier than 2025.

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