Know what electricity costs.

The average spot electricity price in Finland in September 2026 was 5,70 c/kWh excluding VAT, or 7,15 c/kWh with 25,5 % VAT (Nord Pool). In August 2026 the average was 4,13 c/kWh (VAT 0). The seller's margin, transmission and electricity tax are added to the price.

The electricity tax for households (tax class I) is, from 1.4.2026, 2.325 c/kWh excluding VAT: energy tax 2.24 c/kWh and security of supply fee 0.085 c/kWh. With VAT it is about 2.92 c/kWh. Before 1.4.2026 the tax was 2.253 c/kWh.

In price statistics, a typical flat user consumes 2 000 kWh, a detached house with a sauna stove but no electric heating 5 000 kWh, and a detached house with direct electric heating 18 000 kWh a year. In Motiva's example, a 120 m² electrically heated detached house consumes 18 900 kWh and a 50 m² district-heated flat 3 100 kWh a year.

An electricity bill consists of electrical energy (from the supplier), the network service or transmission (from the network company), electricity tax and 25,5 % VAT. According to the Energy Authority, the total price for a household using 5 000 kWh a year was on average 20,86 c/kWh on 1.11.2025, of which electrical energy was 9,45 c/kWh and transmission including tax 11,41 c/kWh.

You cannot. Electricity transmission is a natural monopoly, and the network company is determined by where you live. The Energy Authority supervises the reasonableness of network companies' pricing. You can freely tender your electricity seller, for example on the sahkonhinta.fi service.

The day-ahead electricity market moved to a 15-minute trading period in autumn 2025 (Fingrid). In a spot electricity contract the price can therefore change every quarter of an hour, and shifting consumption to cheaper periods reduces the bill.

The notice period for an open-ended electricity supply contract is always two weeks for a consumer (Energy Authority). A fixed-term contract is usually valid until the end of the agreed period. The seller must notify of a price increase in writing one month in advance.

An ordinary 6 kW electric sauna heater typically uses about 5–9 kWh for heating and bathing. When the total price of electricity is 20 c/kWh, one sauna session therefore costs about €1–2. With spot-price electricity, heating should be timed for the cheapest 15-minute periods.

Yes. A VAT-liable business deducts the VAT on electricity used in its business, so a company should compare electricity contracts excluding VAT. Electricity tax and transmission charges are costs for a business too, and they cannot be put out to competitive tender in the same way as electricity energy.

According to Nord Pool, the average spot electricity price in the Finnish price area in 2025 was €40.48/MWh, i.e. 4.05 c/kWh excluding VAT (5.08 c/kWh with 25.5% VAT). In 2026 monthly averages have ranged from 1.54 c/kWh in July to 13.72 c/kWh in February.

According to the assessment published by Fingrid on 24.9.2026, electricity is expected to be sufficient if the large power plants and the transmission links to Sweden and Estonia work normally. On a very cold and calm day, consumption may rise to about 15 200 megawatts, while domestic production is sufficient for at most about 12 000 megawatts; the rest is imported.

From 1.4.2026, the electricity tax for tax class II is 0,135 c/kWh (VAT 0), while the tax for class I is 2,325 c/kWh. The lower tax class applies, among other things, to electricity used in industry and professional greenhouse cultivation.
