Finnish spot electricity price today, with transfer and tax

What a kilowatt-hour is made of

On a spot contract you pay for four things with every kilowatt-hour. The first is the energy itself: the exchange price in the Finnish bidding zone for the quarter hour in which you use it. The second is the retailer’s margin, a fixed add-on set in your contract. Those two come on the retailer’s bill. The third is the network operator’s transfer fee, which pays for carrying power from the national grid to your home. The fourth is electricity tax and the security-of-supply fee, collected by the network operator for the state. VAT of 25.5% is added to all of them. Both companies also charge a monthly basic fee that does not depend on how much you use.

The table breaks down the average kilowatt-hour in Helsinki on 17 October 2026. The figures come from the same engine as the calculator above and refresh every day.

Energy makes up about 33 % of the all-in price today. When the exchange price is low, transfer and tax weigh more on the bill than the electricity itself. That is why the spot price alone says little about what power at home costs, and why the same spot price leads to different prices in Helsinki, Espoo and Mikkeli.

The exchange price: 96 prices a day

The wholesale price of electricity in Finland is set on the Nordic power exchange. A price for every quarter hour of the next day is found in the day-ahead auction, where producers’ offers meet buyers’ bids. The auction closes at noon Central European time and the results are usually visible in Finland at about 13:45. Since 1 October 2025 a price is set for every 15-minute period, so a day has 96 prices, and 92 or 100 on the days the clocks change.

Exchange prices are quoted in euros per megawatt-hour before VAT. One euro per megawatt-hour is 0.1 cents per kilowatt-hour, and 0.1255 cents with VAT. On this site every price is already in cents per kilowatt-hour including VAT, because that is how consumer contracts are quoted. Prices come from Nord Pool’s day-ahead price list, and the site’s updater is ready to fetch them from the ENTSO-E Transparency Platform as well.

Transfer fees: same power, different price by address

You can switch electricity retailer but not network operator. The distribution grid is a regional monopoly whose pricing is supervised by the Energy Authority, so the transfer fee depends on where you live. The calculator holds the prices of 72 operators. The table lists, for the 21 largest with their own page, the general transfer price and basic fee and the annual transfer cost for a house using 5,000 kilowatt-hours a year on a 3 × 25 A main fuse. They are ranked by each network’s cheapest transfer product.

The gap is large. Across all 72 networks, transfer costs €185 a year at this consumption in the cheapest (Alva Sähköverkko) and €845 in the dearest (Järvi-Suomen Energia). The difference is more than many households pay in a year of spot-contract margin. A night or time-of-day transfer product can cut the cost if much of your use falls after 22:00 or at night, as with storage electric heating. Compare your own network with all the others in the transfer fee comparison.

Electricity tax and the security-of-supply fee

Electricity tax is an excise duty, and the network operator collects it on the same bill as transfer. According to the Tax Administration’s table, tax class I electricity tax is 2.24 cents per kilowatt-hour and the security-of-supply fee 0.085 cents from 1 April 2026. Before that the fee was 0.013 cents. With VAT a household therefore pays 2.9179 c/kWh on every kilowatt-hour, whether the contract is spot or fixed. Tax class II applies to industry, professional greenhouses and some heat pumps; households are always in class I. More in the electricity tax guide.

The cheapest and dearest hours

On weekdays the cheapest hours in recent weeks have on average been 00–01, 03–04, 02–03 and the dearest 19–20, 09–10, 10–11. The figures come from actual quarter-hour prices on 45 weekdays and refresh daily. The pattern follows demand: it peaks in the morning and early evening and is lowest at night. Wind power often reshuffles the order, so check the day’s real cheapest window in the calculator.

The calculator finds the cheapest continuous window for the length you set. Charging a car for three hours or heating the sauna for an hour and a half? Set the length and see when starting is cheapest. Today the cheapest two-hour window in Helsinki starts at 04:30 and averages 9.44 c/kWh. The appliance calculators show directly in euros what a sauna, charging an electric car or a wash costs.

Spot or fixed-price contract

Over the last twelve published months the average spot price has been 7.07 c/kWh including VAT. The all-in price of a spot contract depends on when you use electricity, and a fixed contract pays off only if you sign it at the right price. The comparison calculator works out which would have been cheaper on your annual consumption and the fixed price at which both would have cost the same. Transfer and electricity tax are identical in both cases, so they do not affect the choice.

The calculator’s default margin of 0.51 c/kWh and monthly fee of €4.78 are the medians of the 5 consumer spot contracts listed in the Energy Authority’s price comparison. Replace them with your own contract’s figures.

How this page stays up to date

Prices are fetched automatically three times a day: in the afternoon after tomorrow’s prices are published, again an hour later as a safety net, and at midnight when tomorrow becomes today. Your browser also reads the latest price file whenever you open the page, so the calculator shows the right day even if the page was built yesterday. If the day’s prices are unavailable for any reason, the calculator shows an average-price estimate instead and says so in amber: it is built from actual prices for the same month and type of day, quarter by quarter, or from the official monthly average and the daily profile. It switches to real prices as soon as they are available.

Transfer fees were read from each operator’s own price list and are checked against the source by a script. Taxes come from the Tax Administration’s table. All calculation runs in your browser: your postcode and consumption are sent nowhere. Details on the method page.

Yesterday, today and tomorrow

The table shows how prices move from day to day. A change in the exchange price passes fully into the all-in price, but the relative change is smaller because transfer and tax stay the same. If the spot price doubles from two to four cents, the all-in price in Helsinki rises from about ten to twelve cents, not twofold. On an expensive winter day, when spot reaches tens of cents, the picture flips: energy becomes the largest part of the bill and timing your use matters most.

Recent monthly price levels

A longer series and all-in prices for other operators are on the monthly prices page. Spot prices are usually highest in the winter months, when heating lifts demand and there is little solar power, while plentiful hydro and wind power push prices down in spring and summer.

Two examples of a year’s electricity bill

A flat in Helsinki using 2,000 kilowatt-hours a year, on general transfer and a spot contract at the last year’s average price: energy with monthly fee €209, transfer with basic fee €173 and electricity tax €58, a total of €440 a year or about €37 a month. At low consumption transfer and fixed fees are the largest part of the bill, and energy is less than half.

An electrically heated house in Elenia’s area using 18,000 kilowatt-hours a year, on night transfer and the same spot contract: energy €1,423, transfer €1,171 and electricity tax €525, a total of €3,119 a year, €260 a month on average. In reality winter bills are several times summer ones. Work out your own month in the electricity bill calculator.

Five ways to pay less

1. Check your transfer product. With electric heating and high consumption, night or seasonal transfer can be hundreds of euros a year cheaper than general transfer. Operators usually switch products free once a year.
2. Move flexible loads to cheap hours. Car charging, the water heater, washing and drying can usually be timed for the night or another cheap window.
3. Compare margin and monthly fee. On spot contracts they are the only things that separate retailers. A difference of a few tenths of a cent adds up at high consumption.
4. Do not keep a larger fuse than you need. Many operators’ basic fee jumps from 3 × 25 A to 3 × 35 A. Downsizing can itself cost a connection change, so ask your operator first.
5. Follow your consumption. The operator’s portal shows your use by the hour or quarter. It reveals the biggest consumers and whether your use falls in expensive hours.

Why other price sites show a different figure

Most Finnish spot-price sites show the exchange price alone, with or without VAT. That is the right figure for the energy, but it does not tell you what using a kilowatt-hour costs. When the exchange price is two cents, a consumer typically pays ten cents or more once transfer and tax are added. The cheapest hour does not always change, but the size of the saving does: on general transfer the fee and tax are the same at every hour, while on time-of-day transfer nights are cheaper. That is why this page prices every quarter hour on your own transfer product.
