Slightly over 1,000 megawatts (MW) of new wind power capacity was built in Finland in 2025, bringing the country’s total capacity to nearly 9,500 MW. Wind power is still most strongly concentrated in the Ostrobothnia regions. The amendment to the Land Use and Building Act currently being prepared by the Government will in the future steer wind power construction even more strongly toward Northern Finland and farther away from residential areas.
The year 2025 was an active year for wind power construction in Finland, with 1,023 MW of new capacity completed. At the end of the year, Finland had 2,002 wind turbines with a combined capacity of 9,433 MW. According to statistics from Renewables Finland, no wind turbines were decommissioned during the year, and wind power capacity increased especially in the Ostrobothnia regions.
Wind power plays a key role in the electrification of industry and in launching the hydrogen economy. Growth in industrial production requires more energy. As electricity demand increases, Finland has the potential to add new wind power capacity rapidly, at an estimated 1,000–2,500 MW per year.
“Wind power is the fastest and most cost-effective way to meet the growing demand for clean electricity. Finland’s strength lies in the fact that new capacity can be built quickly when industrial investments and the hydrogen economy begin to scale up,” says Anni Mikkonen, CEO of Renewables Finland.
Northern Ostrobothnia remains Finland’s most significant wind power region: 37% of the country’s total wind power capacity has been built there. When all Ostrobothnia regions are combined, their share rises to 78% of Finland’s wind power capacity. After the Ostrobothnia regions, the next largest wind power region is Lapland, which accounts for 8% of Finland’s wind power capacity.
“The fixed minimum distance between residential areas and wind turbines outlined by the Government in the Land Use and Building Act will likely mean that new wind power will continue to be built in Northern Finland rather than in Southern Finland. In practice, this decision will also steer industrial investments to areas with strong electricity production and transmission networks,” Mikkonen notes.
The largest single wind power project completed in 2025 was the 455 MW wind farm in Lestijärvi, Central Ostrobothnia, which is the largest wind farm built in Finland to date.
