Tyrinselkä wind farm – The most efficient wind farm in Finland

The first realized wind farm project Tyrinselkä I is located in Jokioinen municipality. The project development started in 2011, construction started in 2015 and in 2016 the wind farm started its commercial operation. In 2017 the wind farm produced 45.000 MWh of electricity, an equivalent to the electricity demand of 2.000 households.


Tyrinselkä wind farm consists of four Nordex N131 turbines, which have hub heights of 144 m and a total tip height of 210 m from ground level. The nominal power of one turbine is 3 MW, thus the electricity production total of the wind farm is 12 MW. The produced electricity is fed into the national grid through an own substation built next to the existing Caruna Oyj’s 110 kV grid lines. More than 60 landowners have been committed to the project and the project area covers more than 1000 ha of land.


Tyrinselkä wind farm was the most efficient wind farm in Finland with a capacity factor exceeding 43% in 2017.
