To Be Operational (estimate)


Ilmatar is preparing a wind farm with total power of approximately 75-100 MW in the municipalities of Kauhajoki and Kurikka, South Ostrobothnia.

The Harjanneva development area is located between Ikkeläjärvi and Säkkijärvi, approximately 20 kilometres southeast of the centre of Kauhajoki. For the Kauhajoki area, the plan is to build 10 turbines. An additional three wind turbines will possibly be constructed in Kurikka.

A wind power report by the Regional Council of South Ostrobothnia outlines this area as a potential area that is to be investigated further.



Construction in Harjanneva is projected to start in 2025 or 2026 with power generation set to commence around 2027.


Asset Management

Upon completion, Ilmatar Service Oy, a subsidiary of Ilmatar Energy, will take over the wind farm’s technical and commercial management.



Ilmatar is furthering the Harjanneva wind farm project towards the construction phase through its project company, Ilmatar Kauhajoki Oy, which is domiciled in Kauhajoki.
