The public display of the project’s land use plan draft and EIA report were at the end of 2024. The goal for 2025 is to present the land use plan proposal for public display, followed by the approval process. The Ooperi project has been developed with great dedication and in close collaboration with local landowners. Project development has progressed smoothly according to plan. Extensive studies conducted in the area have confirmed its excellent suitability for wind power production. Ilmatar continues to develop the project with the goal of efficiently and sustainably renewable energy production in Seinäjoki.

Article / Opinion
Fixed setback distance between wind turbines and residential areas may slow down the green transition
The Finnish Ministry of the Environment has proposed a fixed setback requirement for wind turbines, which would significantly limit the areas suitable for renewable energy development. If energy companies lose interest in investing in renewable energy, the progress of the green transition — as outlined in Finland’s national climate and energy strategy — will also slow down. Additionally, Finland’s attractiveness as a destination for international industrial investment would decline, weakening the country’s competitiveness.
