Ilmatar is preparing a wind farm with total power of approximately 75-130 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.

The Kauhajoki City Government has approved Ilmatar’s planning initiative to start planning for the Harjanneva area in Kauhajoki at its meeting on 1.11.2021, and the participation and assessment plan (OAS) has been made available for public inspection from 24.2.2022. The Kauhajoki Technical Committee decided to open the draft plan for the project to public inspection on 31 October 2023.

The environmental impact assessment (EIA) procedure for the Harjanneva wind power project has started and the EIA report for the project has been published by the South Ostrobothnian Regional Development Centre on 1 November 2023.
