Electricity Supply in Finland Will Remain Sufficient Even During Winter Peak Demand – Provided We Use It Wisely
Finland is part of the Nordic electricity market. Electricity is imported and exported between neighbouring countries via cross-border connections according to grid capacity and market prices, which helps balance availability and cost.
One topic of discussion in the Nordic region has been Norway’s introduction in October 2025 of a fixed-price electricity contract – a so-called price cap. This could remove incentives for Norwegian consumers to save electricity or shift consumption to cheaper hours when supply is plentiful. If Norwegian consumers significantly reduce their willingness to save electricity, it could create imbalances in the Nordic electricity market. However, the change in Norway is not expected to have major effects on the balance of Finland’s electricity market or on prices.
According to recent estimates by the transmission system operator Fingrid, Finland’s electricity supply for winter 2025–2026 is fundamentally in good shape. Domestic production capacity and transmissions connections – such as the Aurora Line between Finland and Sweden, completed in November 2025 – support the stability of the electricity system even during peak demand. Fingrid does note, however, that supply could weaken on extremely cold and calm days when wind power is unavailable or if transmission connections fail.
Smart Electricity Use and Flexibility Help Avoid Shortages
If electricity supply were to deteriorate severely – meaning domestic production and imports cannot meet demand – consumption may need to be temporarily restricted. This situation is referred to as an electricity shortage.
To maintain the stability of Finland’s national grid, Fingrid Oyj, which is responsible for ensuring sufficient electricity supply, would instruct regional network operators, including Oulun Energia Sähköverkko, to implement controlled outages in areas without sites critical to society.
Although the risk of shortage is not currently acute, using electricity wisely and remaining flexible during the winter months is essential to avoid this risk. It is advisable to schedule electricity use for the cheapest hours of the day and avoid unnecessary consumption during peak load periods.
At Oulun Energia, we also prepare thoroughly for winter. Our power plants have been maintained as scheduled over the summer to ensure high operational reliability when electricity and heat production are most needed. Together, we can prevent shortages and avoid regional power cuts.
