How to Read Your Finnish Electricity Bill — Every Line Explained
Your bill has 5–7 lines. Most people glance at the energy row and move on. The problem: the network transfer fee (siirtomaksu) is often larger than the energy row — and it's the part nobody explains. Here's a line-by-line breakdown.
The electricity bill lands once a month, and most people check only the total. When it feels high, they look at the energy row — but that's precisely the wrong place to start. For many Finnish households, the network transfer fee is larger than the energy cost, and it's almost entirely invisible in the way bills are typically presented. This guide walks through every line in the order they appear on a typical Finnish bill.
There's nothing complicated about the bill once you know what each line means and who controls it. Some rows you can negotiate; most you can't. Keeping that distinction in mind is the most useful thing you can take from this article.
What a Finnish electricity bill contains: five main components
A Finnish electricity bill is actually split across two separate invoices: one from your electricity seller (energiamyyjä) and one from your local grid operator (verkkoyhtiö). If that split is unfamiliar, the article why do I get two electricity bills in Finland covers the background. This guide treats both invoices together, since together they form your total electricity cost.
The standard line items are:
- Energy — from your electricity seller
- Network transfer fee (siirtomaksu) — from your grid operator
- Basic fee (perusmaksu) — fixed monthly charge from your grid operator
- Electricity tax (sähkövero) — tax class I or II
- Security of supply fee (huoltovarmuusmaksu)
- VAT on all of the above
Some bills also include a reactive energy charge or a peak power fee if you have unusually high demand spikes. For a typical household, these don't appear.
Energy row: the only part you can shop around for
The energy row is what electricity sellers compete on. The price is quoted in cents per kilowatt-hour (c/kWh) and can be fixed, spot-linked, or somewhere in between. According to Energiavirasto's retail electricity page, Finland has over 70 electricity sellers and you can switch at any time with no notice period on rolling contracts.
On a spot-price contract, the energy row changes each month based on market prices. On a fixed contract, it stays constant for the contract term. In February 2026, Energiavirasto's price comparison showed fixed 12-month contracts ranging from 7.5–11.5 c/kWh, while the monthly average for spot electricity varied between 3–13 c/kWh over the winter-spring period.
Network transfer fee: the part you can understand — but not shop around for
The network transfer fee is what your grid operator charges for moving electricity from the national grid to your home. Your grid operator is a local monopoly: you can't switch from Caruna to Helen's network just because you live in Helen's service area. Energiavirasto regulates network tariffs through a reasonable-return framework, which caps grid operators' margins. In practice, you can't shop around for the transfer fee — but it also can't rise without limit.
The transfer fee is quoted in c/kWh like the energy price. In 2025, transfer fees ranged from roughly 2.5–7 c/kWh across different grid operators before taxes. Caruna, Finland's largest grid operator with around 700,000 customers, publishes its tariffs on its website. Helen's network tariff in Helsinki has traditionally been lower than rural networks because urban grids are denser and distribution is more cost-efficient.
"What's the difference between the basic fee and the transfer fee? Do both come every month or is one of them a one-time charge?"
Suomi24 user, electricity forum, 2024
That's a fair question. The basic fee and the transfer fee are two separate things, though both come from your grid operator. The basic fee is a fixed monthly charge — its size depends on your main fuse rating. The transfer fee is a variable charge based on how much electricity you use: the more you consume, the higher the transfer fee. Both appear every month.
Basic fee: your fuse size determines it
The basic fee is a flat monthly charge tied to your main fuse rating. A typical detached house has a 3×25 amp fuse; a flat often has 3×16 A or 3×25 A. From Elenia's tariff schedule, a 3×25 A fuse puts the basic fee at around €10–16 per month depending on the grid operator. If your fuse rating is oversized for your actual needs — installed larger than required — you can reduce the basic fee by requesting a downgrade from your grid operator. It's the operator's job to make the change; just call their customer service.
Electricity tax: two classes, one that applies to you
The electricity tax is an excise duty collected by the state. According to the Finnish Tax Administration, Finland uses two tax classes:
- Tax class I (households and services): 2.24 c/kWh (2025 rate)
- Tax class II (industry and data centres): 0.05 c/kWh
Households always pay class I. The tax is added directly to your bill — you don't file it separately.
Security of supply fee: a small line, a real purpose
The security of supply fee is 0.013 c/kWh. It's small but mandatory. The fee goes to Huoltovarmuuskeskus (the National Emergency Supply Agency), which maintains critical energy reserves. You can't remove or negotiate this line. At 5,000 kWh annual consumption, it works out to roughly €0.65 per year — it doesn't move the needle financially, but it shows up on every bill.
VAT: 25.5 percent on everything
Electricity VAT in Finland is 25.5% (following the 2024 increase). It's applied to all the components above. Depending on how your bill is formatted, VAT may appear as a single line at the bottom or next to each component. Households have no VAT deduction right, unlike business customers.
A worked example: a detached house bill, line by line
Here's a realistic monthly bill for a detached house in Tampere in 2025. Consumption: 500 kWh/month. Electricity seller: fixed contract at 9.0 c/kWh. Grid operator: Tampereen Sähköverkko, 3×25 A fuse. Based on Tampereen Sähköverkko's tariff schedule and the Finnish Tax Administration's tax rates:
| Line item | Calculation | Amount (excl. VAT) |
|---|---|---|
| Energy | 500 kWh × 9.00 c/kWh | €45.00 |
| Network transfer fee | 500 kWh × 3.80 c/kWh | €19.00 |
| Basic fee | 3×25 A, fixed/month | €12.50 |
| Electricity tax (class I) | 500 kWh × 2.24 c/kWh | €11.20 |
| Security of supply fee | 500 kWh × 0.013 c/kWh | €0.07 |
| Subtotal (excl. VAT) | €87.77 | |
| VAT 25.5% | €87.77 × 0.255 | €22.38 |
| Total | €110.15 |
The pattern here is striking: the energy row is €45.00, but the transfer fee + basic fee + electricity tax add up to €42.70 — almost the same amount. Energy and grid costs split the bill roughly in half. If consumption goes up (say, an EV charging at home), the energy row grows faster — but the transfer fee and electricity tax follow consumption at the same rate, so they grow too.
Why understanding the transfer fee saves more than switching sellers
This is the part most people miss. The energy market is competitive: sellers fight for customers and margins are thin. The transfer fee is monopoly-priced — but it varies significantly between grid operators. Caruna's Plus tariff (time-of-use pricing) can be 30–40% cheaper than the standard tariff if your household uses a lot of electricity at night — for example, an EV charging overnight or a hot-water boiler running on off-peak rates.
Energiavirasto's regulatory framework caps grid operators' returns, but it doesn't stop them from offering multiple tariff options. It's worth asking your grid operator whether a two-rate tariff (day/night or winter/summer) is available. That question costs nothing — and the answer could save you tens of euros a year.
"How is the transfer fee calculated? Is it the same for everyone or does it depend on how much you use? It always looks like a big chunk on my bill but nobody explains where it comes from."
Vauva.fi user, household finances forum, 2025
The transfer fee is calculated as c/kWh × monthly consumption. If consumption rises, the transfer fee rises proportionally. The basic fee doesn't change with consumption — it's the same whether you use 100 kWh or 1,000 kWh in a month.
Vantaan Energia, Elenia, Caruna — your grid operator matters more than you think
One thing most people don't realise: the same consumption costs different amounts in different municipalities, because grid operators charge different transfer rates. Vantaan Energia Sähköverkot's tariff sits at a different level from Elenia's rural rate, for instance. Energiavirasto publishes an annual comparison of grid operators' transfer pricing — in the most recent comparison, the gap between the cheapest and most expensive operator was over 3 c/kWh. At 5,000 kWh annual consumption, that's more than €150 difference in transfer fees alone.
You can't choose your grid operator — it's determined by where you live. But if you're thinking about where to move, it's one factor worth checking.
Datahub and reading your consumption data online
Fingrid's Datahub is the system where all Finnish electricity consumption data is stored. Every consumer can log in with their consumption point identifier (käyttöpaikkatunnus) and see hourly or 15-minute consumption data. This is invaluable if you want to understand why your bill went up. The biggest consumption spikes show clearly — in most homes it's electric heating or an EV.
My view: the bill doesn't tell you enough — and that's by design
The Finnish electricity bill is structured to be legally complete but not particularly informative. The line items are correct, but there's no benchmark: no bill tells you whether your transfer tariff is expensive or cheap compared to the household two towns over. Energiavirasto has encouraged consumers to use its own electricity price comparison service actively. I genuinely recommend it — comparing your current contract against the market takes five minutes and will tell you whether your energy deal is still competitive.
What the bill doesn't tell you: how much cheaper things would be if you shifted more consumption to off-peak hours. That information lives in your Datahub consumption curve — and it's the single best starting point if you want to reduce your electricity costs.
