Assumptions
Spot is the FI bidding-zone day-ahead price for the quarter, plus 25.5% VAT (also on negative prices). Transfer fee per the operator’s price list; time-of-day and seasonal windows, and how public holidays count, as worded in the operator’s price list, Finnish time. Electricity tax class I. Monthly fees are not in the per-kWh price. Method and sources

How tomorrow’s price is formed
In the Nordic exchange’s day-ahead auction, producers and buyers submit bids for every quarter hour of the next day. The auction closes at noon and an algorithm finds, for each bidding zone, the price at which supply meets demand within the limits of the interconnectors. Finland is its own bidding zone, so its price can differ from Sweden’s or Estonia’s when the links are full. Tomorrow’s prices are final once published and the same for every spot customer, before margin, transfer and taxes.
Tomorrow’s prices for your own network
The calculator is preset to Elenia’s night transfer, a common choice in electrically heated houses. On night transfer the fee drops to the night rate at 22:00 and returns to the day rate at 07:00. That makes night quarters cheaper all-in than the exchange price alone suggests, and there can be a clear step between the quarters starting at 21:45 and 22:00 even if the exchange price does not move. Switch the operator and transfer product to your own; on general transfer the fee is the same around the clock.
Planning tomorrow in three steps
- Open the page after 13:45 and check that the price status refers to published prices, not an estimate.
- Set the length of the cheapest window: three hours for charging an electric car, say, or an hour and a half for the sauna. The calculator shows when the window starts and its average price.
- Schedule the appliance. Many electric cars, chargers, water heater controls and washing machines have a timer that lets you start at exactly the right quarter.
The appliance calculators show directly what charging an electric car, heating the sauna or a wash costs tomorrow at the cheapest and dearest start.
When tomorrow appears as an estimate
In the morning tomorrow’s prices do not exist yet. The calculator then shows an average-price estimate and says so in amber. It is based on actual quarter-hour prices for days of the same month and type, weekday or weekend. While the archive does not yet hold enough days of that month, it uses the official monthly average with a typical daily rhythm on top. The estimate gives a fair picture of whether nights and mornings are usually cheap, but it knows nothing of tomorrow’s wind, temperature or a nuclear plant’s annual outage. When real prices are published the calculator switches to them on its own, with no need to reload.
Tomorrow’s prices and your contract type
Tomorrow’s quarter-hour prices apply directly only to a spot contract. On a fixed-price contract energy costs the same at every moment, and timing only matters if your transfer product is time-of-day or seasonal, where the saving comes from the transfer fee alone. On a spot contract timing saves on energy and possibly on transfer too. Compare contract types on your own consumption with the spot or fixed calculator and read about quarter-hour pricing if your contract has moved from hourly to quarter-hour prices.
