The order is the second Vestas has received from developer TuuliWatti Oy. The turbines will go to a project in Olhava in the west of the country, off the Gulf of Bothnia.
It is the second Vestas order from TuuliWatti Oy this year. In June, it ordered 18MW of V112s.
Vestas described the order, which was its first for a number of years, as a breakthrough for its operations in the country.
The introduction of Finland’s long-awaited feed-in tariff system (FIT) for wind-generated energy in January 2011 marks a turning point for a government eager to release the untapped potential of the country’s wind-power capacity.
The country's long-term ambition, published in 2008 and included in the national action plan, centres on driving interest and capital investment in onshore and offshore projects. The report sees installed wind-power capacity rising to 2GW by 2020, with around 1.2GW offshore.
