Is the shift back to fixed electricity contracts coming — has the spot peak passed?

Why did the electricity bill rise even though the price fell — the 2026 invoice anatomy
Spot prices fell in spring 2026, yet many Finnish bills stayed flat or even climbed. Transfer fees, taxes and fixed charges are often larger than the energy line itself.
How much electricity does a Finnish sauna use — kiuas size and timing decide
6, 8 or 10 kW kiuas? A typical home sauna uses about 520 kWh a year, but timing the heat-up around spot prices can cut the cost by 30–40%.
Is Finland self-sufficient in electricity — and what does it mean for your bill?
Finland posted an 8 TWh annual surplus in 2024, yet still imports from Sweden and Estonia on freezing winter nights. Why the yearly and the hourly balance tell different stories.
Why electricity is more expensive in Finland than in Sweden — and when that changes
The FI–SE3 bidding-zone price gap routinely runs €30–50/MWh. Aurora Line and Fenno-Skan still aren't enough — which is why a Finnish household pays more.
Olkiluoto 3 and the electricity price: what 1,600 MW of nuclear actually does to your bill
OL3 produced 14 TWh in 2024 and cut wholesale prices by about €14/MWh. The spring 2025 outage also showed how heavily Finland leans on a single reactor.
How Nord Pool works: how Finnish electricity prices are set every hour
In Nord Pool the most expensive plant that is still needed sets the price for every kWh that hour. Nuclear and hydro almost never set the price — gas or biomass usually does.
Why do Finnish electricity prices go negative — and what does it mean for you?
Finland recorded 447 hours of negative electricity spot prices in 2025. Seeing a minus sign in the app doesn't mean money arrives in your account. This article explains what's actually happening.
Wind power and spot electricity price in Finland: what 9,433 MW means for your bill
Finland's installed wind capacity more than doubled in four years. Wind keeps average prices low — but it also creates sharper price spikes when the wind drops. If you're on a spot contract, both sides affect you.
Finland's cheapest electricity in Europe 2025: four reasons it happened
Finland repeatedly landed at or near the bottom of Nord Pool's price table in 2025. Four structural factors drove it there, none of them accidental. But cheap wholesale power doesn't translate one-for-one into a cheap household bill.
Hybrid electricity contracts in Finland: what you're actually paying for
Helen Välkky, Oomi Jousto, Fortum Duo. The marketing promises the best of both worlds: fixed-price protection and spot-price cheapness. We ran the actual Q1 2026 numbers for an 18,000 kWh/year detached house. The result is more modest than the brochure.
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.
When to charge your EV cheaply in Finland — spot price charging guide
The standard advice is "charge at night." That holds in winter — but not year-round. On a spot contract, the real question is: when does the 15-minute price fall below your target rate? The answer shifts by weekday, season, and wind conditions.
When is electricity cheapest in Finland? Weekly patterns explained
The standard answer is "at night" — and it's wrong about half the time. Wind power has turned windy weekend afternoons into Finland's cheapest electricity hours, not the small hours of a weekday. Here's Q1 2025 data, timing tables, and what a washer, tumble dryer, and dishwasher can actually save you.
Finnish electricity providers compared 2026 — who sells spot cheapest?
Most provider comparison sites in Finland run on affiliate fees. This one doesn't. Marginals and monthly fees are taken directly from each provider's own pages in April 2026. Before you read the table, there's one thing almost no comparison site mentions: the transfer fee covers 50-60% of your bill.
Fixed vs. spot vs. hybrid electricity contract: which is right for you in Finland in 2026?
Most people answering the fixed-vs-spot question get it wrong. Hybrid contracts are marketed as the safe middle ground, but they are often the most expensive option precisely when prices spike. Q1 2026 data and a worked household calculation show who actually benefits from each type.
Finland's security-of-supply fee rises in April 2026
The huoltovarmuusmaksu jumped from 0.013 to 0.085 cent/kWh on 1 April 2026. It's the smallest line on your electricity bill -- but it funds the reserves that stopped Finland's energy supply from collapsing when Russian gas deliveries ended.
Quarter-hour electricity pricing: what does 15-minute billing mean for your bill?
Spot electricity has been billed in 15-minute intervals since 2025, not hourly. An evening sauna can now land on a pricier quarter-hour, a night charge on a cheaper one.
