Study: Growth of electric cars could cause electricity deficit in Finland by early 2030s
A rapid increase in the number of electric vehicles and peak loads from charging could create a risk of electricity shortage in Finland as early as the early 2030s, especially during cold winter periods, according to a study by Aalto University.
Researchers at Aalto University warn that the rapid increase in electric vehicles in Finland could lead to a risk of electricity deficit as early as the early 2030s. Cold periods at the start of winter will be particularly vulnerable, as electricity consumption peaks while wind power generation typically decreases due to weather conditions, reports YLE.
Finland currently has around 300,000 rechargeable electric vehicles, and their number is expected to double or triple within the next four years. Ilona Malmi Puro, a doctoral candidate in energy engineering, notes that under current system development trends, significant electricity deficits could occur during windless winter periods as early as the beginning of the next decade.
According to the researchers, managing the timing of electric vehicle charging will play a key role. Shifting charging to low-load periods, such as night or windy weather, could reduce pressure on the power system. Total electricity demand in the country is forecast to increase by 20–45% by 2030. A significant share of generation already comes from wind power, making the system more sensitive to weather fluctuations and peak loads.
The study emphasizes the importance of flexible electricity consumption. If users charge their cars more often at night, during windy weather, or during low-demand periods, the risk of capacity deficit could be significantly reduced.
