Finland’s total electricity demand is projected to climb by 20 to 45 percent by the start of the next decade, according to a study reported by Yle News. The forecast points to a sharp increase in pressure on the country’s power supply as electrification accelerates.

The study says the growing popularity of electric cars is one of the main reasons behind the expected rise. That makes the finding relevant not only for energy companies and grid operators, but also for households and businesses that depend on stable and affordable electricity.

What remains unclear is how quickly supply, grid capacity and new generation can keep up with the demand growth. The estimate suggests Finland may need to prepare for a much tighter electricity balance in the years ahead.
