Wind power in Finland

Do wind turbines generate electricity in cold winter temperatures?

Do wind turbines contribute to meeting cold winter consumption peaks?

People generally observe wind conditions from under two meters above the ground and usually in places such as sheltered urban areas, next to office blocks or in the forest, which are far from where wind power is actually produced. At one hundred meters above ground level on the coast or on the top of a fell in Lapland, the wind blows strongly even on very cold days.

Finnish wind resources are greater in the winter months and significantly higher than in the summer. Wind energy statistics compiled by VTT (Technical Research Centre of Finland) show that 60% of annual wind power production takes place in the winter months (October-March). Wind speeds near the ground vary significantly throughout the year offshore, in coastal regions and highlands, but inland monthly average wind speeds show little variation. Wind speeds increase with distance from the ground (Finnish Wind Atlas).

The impact of wind power in meeting consumption peaks can be analyzed by evaluating how much other energy production is not required due to the construction of variable production wind power. Based on research findings, the wind power capacity value at a national level is approximately the same as the average power production in power systems with low wind power penetration. As wind power penetration grows, the capacity value falls.
