Coordinating hydropower and wind power satisfies hourly operation requirement. Swedish government's target is to have 100% renewable electricity production by 2040. Currently, hydropower contributes the majority of renewable electricity generation of the country. The wind power capacity has increased significantly in the past decade.
In the recent decade, wind power capacity in Sweden has increased significantly. The electricity generation from wind power in 2009 was 2.5 TWh, which was 1.87% of the total electricity generation of the year. In 2019, it increased to 19.9 TWh, which is 12.1% of the total electricity generation.
The target wind power capacity 25,000 MW is around triple of current existing wind power capacity in Sweden. In other words, if the wind power capacity can be tripled from 2019, it is possible to reach a 100% renewable electricity generation system in Sweden.
