Historical Pattern for Winter Electricity Prices
Every winter, electricity prices rise in the Nordics. This is a well-known pattern driven by increased heating demand, shorter days with lower solar production, and sometimes lower water levels in Norwegian reservoirs. Winter 2021/2022 saw record prices, while 2023/2024 was milder thanks to full reservoirs.
Factors to Watch in Winter 2025/2026
Hydropower Reservoirs in Norway and Sweden
Reservoir levels in autumn determine the price outlook. If reservoirs are well-filled when winter sets in, it dampens price increases. Low levels, on the other hand, create a worse starting point.
Weather Forecast and Temperature
A cold winter increases demand. Meteorological models point to normal temperatures for 2025/2026, but uncertainty is high. Each degree lower temperature increases Nordic electricity consumption by approximately 1–1.5 TWh per week.
European Gas Prices
Natural gas prices often set the floor for European electricity prices. Geopolitics, LNG imports, and Europe's storage situation directly affect Nordic spot prices via export cables.
Wind Power
Nordic wind power capacity has grown significantly. Good wind periods can push prices down considerably, even during cold winters. Cold, calm weather — "Dunkelflaute" — is the most dangerous combination.
What You Can Do
Regardless of price levels, the same strategy applies: shift your electricity consumption to the cheapest hours. SpotPris helps you with:
