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.
Fixed or spot? It is the question Finnish households revisit every winter. The answer got harder at the start of 2026: January and February pushed Nord Pool Finland area monthly average prices to 14.72 c/kWh and 29.02 c/kWh respectively, while March collapsed to under 4 cents. The full Q1 average landed around 11–12 c/kWh for spot customers, while many fixed contracts were priced at 9–10 c/kWh when signed. Vattenfall Finland published an analysis of Q1 2026 spot price swings, attributing the peaks to cold spells in January and February and low wind power output.
This article works through what those numbers mean for each contract type. The calculation is based on a Helsinki detached house consuming 20,000 kWh per year. After the numbers, there is a recommendation by household profile.
Three contract types — how they actually work
A fixed-price contract locks in a cent-per-kWh rate for the full contract term, usually 12 or 24 months. The price does not move regardless of what happens on Nord Pool. Because the supplier absorbs the market risk, the fixed rate is always set somewhat above the expected long-run spot average. In spring 2026, typical 12-month fixed offers were running at 9–10 c/kWh.
A spot contract charges the Nord Pool Finland area spot price each hour, plus the supplier's margin, which is typically 0.2–0.5 c/kWh. The Energy Authority's consumer guidance notes that spot contracts run until further notice and can be terminated with one month's notice, which makes them the most flexible option. Whether spot ends up cheaper or more expensive than fixed depends on how market prices behave relative to whatever fixed offer was available when the decision was made.
A hybrid contract — called kulutusvaikutteinen in Finnish — blends a fixed base price with a monthly consumption-weighted adjustment. The Energy Authority added hybrid contracts as a separate comparison group on Sahkonhinta.fi because their structure is harder to read than fixed or spot. The adjustment can lower the bill if consumption falls on cheap hours, but it can also raise it if usage clusters on expensive ones. Oomi's Jousto product publicly states a consumption-effect range of -3.9 to +1.6 c/kWh.
A reader question from Suomi24
"Is spot always cheapest over the long run, or can fixed make sense if electric heating is the primary heating method? January 2024 and February 2026 are making me nervous."
Suomi24 user, electricity section, 2026
Not always. Spot is statistically cheaper over time, but an individual winter can break that pattern. For an electrically heated house consuming 10,000 kWh in a cold month, a February average of 29 cents/kWh produces a monthly energy bill of about €2,900. A fixed contract caps that at around €900–1,000. That is a concrete difference, not a rounding error.
A second question from Flashback forum
"Byta elbolag efter 20 ar, vad ska man valja? Har bott i Finland i 30 ar, aldrig brytt mig om elavtalet."

Twenty years with the same supplier, contract never renewed. In most cases that means an open-ended default tariff priced well above current market offers. Switching almost always pays. Which contract type to pick is the question after that.
The euro calculation: Helsinki, 20,000 kWh per year
Three contracts, same house, same assumptions. Annual consumption of 20,000 kWh spread evenly across the year — roughly 1,667 kWh per month. Transfer charges and electricity tax are identical across all three and excluded from the comparison; only the energy component is shown.
| Contract | Energy price c/kWh | Annual energy cost | Note |
|---|---|---|---|
| Fixed 12-month | 9.5 c/kWh | €1,900 | Typical spring 2026 offer |
| Spot | ~7.0 c/kWh (2025 avg) + 0.3 c margin | €1,460 | Based on Energiavirasto 2025 stat: avg spot ~5.1 c/kWh incl. VAT 25.5%; margin included |
| Hybrid (Oomi Jousto type) | 8.8 c/kWh base + avg consumption effect +0.4 c | €1,840 | Even consumption profile; in a spike year can reach €1,950–2,000 |
These figures are indicative. Spot's actual annual cost varies year to year. The 2025 full-year average of ~5.1 c/kWh including VAT 25.5% is from Energiavirasto's published data; the VAT-exclusive estimate used here is approximately 7.0–7.3 c/kWh including supplier margin. The abnormal Q1 2026 price run is not reflected in the 2025 annual average.
Over a full year, spot wins clearly in this scenario. Hybrid loses to fixed by only €60, but would have beaten fixed in a quieter year. It never beat spot in this calculation.
The counterintuitive problem with hybrid: it costs most when it hurts most
Here is the blind spot in hybrid marketing. The product is sold as safety: you do not pay the full spot price, but you still share in cheap hours. The problem is in how the consumption adjustment is calculated.
When spot prices spike to 29 cents in February, a hybrid customer pays their base rate plus whatever portion reflects their own usage falling on expensive hours. The typical household that heats in the evening and runs appliances around the morning commute lands precisely in the high-price windows that push the consumption effect positive. At that moment, hybrid is cheaper than full spot — but it gives no fixed-price ceiling. The customer pays more than under a fixed contract and more than they would have paid under spot in a quiet winter.
The Energy Authority stated in its Sahkonhinta.fi service that hybrid contracts cannot be compared with fixed or spot on a simple basis for exactly this reason: the consumption effect makes the price personal. The Energy Authority states clearly that the comparison tool cannot account for the consumption effect because individual hourly usage data is not available. From a consumer's point of view: you cannot properly compare hybrid without your own consumption profile.
Nearly half of Finnish households already pay a time-of-use price
According to Energiavirasto, close to half of Finnish households now have a contract where timing of consumption affects the bill. That includes both spot and hybrid contracts. At the end of 2025, spot contracts covered 34% of households, and roughly a third of fixed-term contracts were hybrids. Hybrid contracts were tracked as their own category for the first time.
The figure also tells you that a significant share of households have moved to a product whose pricing logic they may not fully understand. A hybrid works well if you genuinely shift washing machine loads and EV charging to cheap overnight hours. Without timers, the marketed flexibility exists only on paper.
Household profiles: which contract for whom
Spot makes sense if
- you have an EV or ground-source heat pump that can be scheduled
- annual consumption is high (above 15,000 kWh) and you are willing to be active
- a spike month would not wreck your monthly budget
- you have managed spot before without losing sleep over winter prices
Fixed makes sense if
- electric heating is your primary heating method and you cannot schedule usage
- the monthly budget is tight and a surprise bill is not manageable
- you do not want to follow market prices actively
- you are moving or expect a life change soon (an open-ended fixed contract can be terminated; a 12-month fixed contract usually cannot without a penalty)
Hybrid rarely beats the other two
Hybrid is best when consumption is partly schedulable but not fully. For example: household appliances can be timed, but electric heating responds to outdoor temperature and cannot wait for cheap hours. In that scenario, hybrid is a reasonable compromise. It never provides the ceiling of a fixed contract or the floor of spot in a cheap year. It sits in the middle without clearly winning from either direction.
What Q1 2026 taught us: a contract is not a set-and-forget decision
January 2026 was a reminder that spot risk is not theoretical. According to Vattenfall, the January 2026 Finland average was 14.72 c/kWh and February was 29.02 c/kWh. March fell below 4 cents. The Q1 period as a whole was more expensive for spot customers than most fixed contracts would have been over the same months.
This does not mean fixed is always better. It means the contract choice is a decision about risk tolerance. Energiavirasto published its 2025 household electricity figures: the average bill fell 2% versus 2024, and renewing a contract paid off. Not renewing generally costs the most.
A Finnish market specific: the Electricity Market Act changed on 1 January 2026
The Electricity Market Act amendments took effect on 1 January 2026. One change requires retailers to offer several different contract types, including flexible products. In practice, hybrid and consumption-based contracts will appear in greater numbers. That widens choice, but it also raises the risk of confusion when comparing options.
Suppliers are now legally required to make contract types comparable. Use the Energy Authority's Sahkonhinta.fi comparison service before signing any contract. It is the only neutral reference point.
My recommendation: spot for a 20,000 kWh household, not hybrid
I recommend spot electricity for households consuming 20,000 kWh per year that can schedule at least an EV charge or a washing machine load overnight. The reason is straightforward: over five years of historical data, spot has been cheaper than fixed on average, and hybrid has rarely beaten spot unless the customer could systematically shift consumption to the cheapest hours. Based on my reading of the data, hybrid does not deliver peace-of-mind value proportional to its cost for households that need timers to act on it.
If, on the other hand, the winter electricity bill threatens to exceed €500 per month and that would cause real financial strain, a fixed contract is the right choice. Peace of mind is a tangible benefit with a real price. That price is typically €200–400 per year above the spot option in a normal year.
