Spot electricity price by month: averages and the full price

Monthly averages are computed from our own quarter-hour price archive when every day of the month is in it. For older months we use Nord Pool’s official monthly averages for the Finnish bidding zone. Both are simple averages of every hour or quarter in the month, not weighted by consumption.

Because you use different amounts at different hours. If your use falls in expensive morning and evening hours your consumption-weighted price is above the average; with heavy night use it is below. Your retailer’s bill shows your actual average, which you can compare with this page.

Over the last 62 days the cheapest day was 6 October 2026, with an average spot price of 0.82 euros per megawatt-hour before tax. The dearest was 30 September 2026 at 137.49 euros per megawatt-hour. See daily prices in the home page calculator.

In winter Finnish consumption peaks because of heating, and there is little solar power. In hard frost demand can exceed cheap generation, so the price is set by dearer plants and imports. In spring meltwater, and in summer low demand, push prices down.
