Finnish electricity price statistics

Time series

Monthly day-ahead averages

Each monthly figure is weighted by period duration rather than averaged across quotations. Across the whole record the most expensive month is August 2022 at 32.42 c/kWh and the cheapest August 2024 at 1.57 c/kWh; the extremes of the selected range appear under the pickers.

Hour of day

At what times has electricity been cheapest on average?

Average price by clock hour across the whole series. The cheapest hour is 03:00 at 4.54 c/kWh and the most expensive 09:00 at 12.52 c/kWh. The highest hourly average is 2.8 times the lowest. Weekdays and weekends are separated so their profiles can be compared.

Hours are Finnish local time. These are averages across the whole series, not a forecast: on any single day the cheapest hour can fall anywhere. The weekday and weekend difference reflects the mix of days in this dataset; an individual weekday or weekend day need not follow the overall average.

15-minute settlement

Price varies within the hour too

The Nord Pool day-ahead market moved to 15-minute periods on 1 October 2025. The source API still supplied 60-minute prices to this dataset through 14 June 2026, so intra-hour variation can be analysed from 15 June 2026 onwards. Below is the spread between the priciest and cheapest quarter within the same hour, computed across 1,392 completed hours with all four quarters.

Only completed hours with all four quarters present are counted, so a partially ingested hour cannot masquerade as a calm one. Market quarter-hours for 1 October 2025–14 June 2026 have not yet been backfilled into this dataset.

Market snapshot

Prices of contracts on offer

A cross-section of what is currently offered to Finnish consumers. For fixed contracts the figure is the energy price; for spot contracts it is the retailer’s margin on top of the exchange price. The table uses the ongoing list price; temporary campaign prices and monthly fees are excluded. Only products with a recorded source verification are included. Prices in these groups were source-checked on 12 August 2026 between 18:00 and 18:02.

Market time series

Price history of contracts on offer

Every morning this series records each comparable contract’s energy price or margin, monthly fee, campaign price and online orderability. The regulator’s price statistics describe currently offered products as monthly national weighted averages; this archive records prices at product level, daily. It currently holds 10 days and is extended each morning. The series exists only forward from the start of collection.

Coming: monthly series

Spot vs. fixed realised-cost index

From September 2026 this page publishes a monthly comparison: what spot electricity cost typical consumption profiles in the closed month, and what the same month’s cheapest offered fixed-term contract would have cost. The method is fixed in advance and is not adjusted based on the results.

The monthly chart can also be embedded; it always shows the newest data:

Endpoints and downloads

Each series has its own stable URL. All of them allow browser requests (CORS) and carry a licence header, so they can be called directly from an application or a notebook. The files are language-neutral: their column names are already in English.

CSV files use a comma as the field separator and a dot as the decimal separator. An empty cell means no observations — zero is a price, not missing data. The spot downloads contain derived statistical series, not raw period-level records; the contract-history file is a product-level archive. Responses are cached for one hour and are free to use with attribution.
