How wind power grew in Finland
Finland's first grid-connected wind turbine was a 300 kW test unit at Kopparnäs in Inkoo, built in 1986. The first wind park followed at Korsnäs in 1991, with four 200 kW turbines, and it was dismantled in 2017. Offshore building began at Tahkoluoto off Pori with a 2.3 MW pilot in 2010. Ten 4.2 MW turbines followed there in 2017, on foundations designed to resist severe sea ice.
A ministry grant covering 40% of investment gave wind its first real step in the late 1990s. A feed-in tariff took effect in spring 2011 and paid a target price for 12 years. Capacity grew tenfold from 2009, to about 1,550 MW at the end of 2016. Finnish firms supply parts for the industry. The Switch, founded in Vaasa in 2006, makes generators and converters, and Moventas makes gearboxes.
Finland had 9,433 MW of wind at the end of 2025, after adding 1,023 MW that year. Wind produced more than 22 TWh in 2025, 26.1% of consumption, and is now the second-largest source after nuclear. Defence radar limits building near the eastern border. In April 2026 three ministries found a paid compensation area not currently feasible, and said building there would focus on the roughly 1,000 turbines already approved.
