Ilmatar is preparing a wind farm of about 130 MW in the Pielavesi area of North Savo. The Vornankorpi project area is located between lakes Iso-Panka and Petäjäjärvi, bordering the city of Kuopio to the east and the municipality of Tervo to the south. Up to 13 wind turbines are planned for the municipality of Pielavesi. Wind turbines with a maximum tip height of 350 m are planned for the Vornankorpi area.

The final number of wind turbines, their placement and the land use plan area shall be determined in the coming years during the investigation and land use planning process. There are a number of factors contributing to the end result, such as statements, opinions and discussions with stakeholders related to the impact of the land use plan and the environmental impact assessment (EIA).

The municipality of Pielavesi approved Ilmatar´s land use planning initiative at its meeting on 21 February 2023. The project has received a favourable opinion from the Finnish Defence Forces.

Construction schedule

Construction of the Vornankorvi wind power project is planned to start around 2025-2026 and production is scheduled to start around 2027.

Management and operation

Once completed, the wind farm will be managed by Ilmatar’s subsidiary Ilmatar Service Ltd for high quality technical and commercial management.


Ilmatar is promoting the Vornankorpi wind power project towards the construction phase through the project company Ilmatar Pielavesi Vornankorpi Oy. The project company is based in Pielavesi.
