Finland’s electricity system may face supply pressures in the early 2030s as electric vehicle use grows and power production becomes more dependent on weather, according to new research from Aalto University. The study warns that cold, low-wind periods in early winter pose the clearest risk. Demand rises during those conditions, while wind power output often falls. Aalto University researchers said charging patterns for electric vehicles will play a large role in whether the system copes with peak demand.

Total demand for electricity in Finland is expected to increase by between 20 and 45 percent by the beginning of the next decade.
