Renewables Finland has published updated statistics on Finland’s wind and solar projects. According to the statistics, more than 1,000 MW of new onshore wind capacity was built in Finland during 2025, bringing the country’s total capacity to nearly 9,500 MW. Converted into turbines, this corresponds to a total of 158 new onshore wind turbines.
Of these, a total of 36 turbines were built in Ilmatar’s wind farms. Six turbines at the Korpilevonmäki wind farm in Säkylä, Southwest Finland, were commissioned in March 2025, while 30 turbines at the Pahkakoski wind farm in Ii, Northern Ostrobothnia, started producing clean energy in November.
According to the statistics, Ilmatar built 22% of the onshore wind capacity completed in Finland in 2025, making it the second-largest builder of turbines in the country during the year.
With the completion of the Korpilevonmäki and Pahkakoski wind farms, our own wind power capacity increased by 50%, reaching 650 MW. Ilmatar’s share of Finland’s total wind power production is 7.3%, which is marginally the largest share held by a single owner.
Wind power capacity growth was particularly notable in Northern Ostrobothnia. Our Pahkakoski wind farm, consisting of 30 turbines (186 MW), is the second-largest of the wind farms completed during the year.
Ilmatar’s wind power projects span across Finland. Our long-term and expert project development work has played a key role in establishing our position. In addition to wind power, Ilmatar is also a pioneer in solar power production and the development of energy storage solutions.
Recent statistics also highlight the remarkable growth of solar energy projects in Finland. Ilmatar’s first solar park began operations in Joroinen in 2023, at a time when only a few projects were planned in the country. This year, 224 MW of new solar capacity was completed in Finland.
In Ilmatar’s project portfolio, which exceeds 8000 MW, energy storage solutions complement wind and solar power. These storage systems are essential for balancing production fluctuations, ensuring the reliability of the electricity system, and enabling more effective utilization of renewable energy during peak consumption periods.
“Ilmatar changed its strategy in 2021 to become an independent power producer, so achieving the top position in the statistics at this stage is an accomplishment we can be proud of. Our project portfolio is also one of the largest in Finland, putting us in a strong position to meet the country’s growing electricity demand in the future,” says Jussi Mäkinen, VP, Project Development.
“In my view, Pahkakoski and Korpilevonmäki are concrete examples of Ilmatar’s ability to develop and construct wind farms even in a challenging market environment. Both projects were the only wind power investments completed in Finland in 2023. At the Pahkakoski wind farm, we also introduced a new contracting model. Through close and effective cooperation with our committed personnel and stakeholders, we are able to learn, develop and achieve strong results,” says Petri Ainonen, Director, Construction.
