Spot electricity and Nord Pool — how the Nordic power exchange works in 2026

22 toukokuun, 2026 · Janne Siitari

Spot electricity is Finland’s most common contract type in 2026 — and for good reason. It’s often the cheapest long-term, but understanding it takes some background. In this article we explain how Nord Pool works.

What is Nord Pool?

Nord Pool is the Nordic and Baltic power exchange, founded in Norway in 1991. In Finland it handles about 95 % of all retail electricity — every provider buys from Nord Pool and resells to consumers with a margin added.

Nord Pool prices electricity hourly (Day-Ahead) and in 15-minute steps (Intraday and quarter-hour).

What determines the Nord Pool price?

• Wind power — cheapest when the wind blows
• Hydropower — very cheap, balancing
• Solar — cheap on summer days
• Nuclear — baseload, stable
• Gas and coal — most expensive, used in peak demand

Hourly vs quarter-hour

From early 2025 Finland switched from hourly to quarter-hour (15-minute) pricing, following European market integration. Quarter-hour pricing rewards precise timing.

How does the provider’s margin work?

The provider adds a margin (usually 0.3–0.8 c/kWh) and a monthly fee on top of the spot price. Lowest 2026 spot margins: Aalto Energia (Luotsi 0.34 c/kWh) and Hehku Energia (Hehku Pörssi 0.39 c/kWh). See the full list of cheapest electricity contracts 2026.

How do I shift consumption to cheap hours?

Typically the cheapest hours are:

• At night (23:00–06:00)
• Summer days (May–August)
• Weekend midday

Actions you can shift to cheap hours:

• EV charging — use scheduled charging
• Hot water heater — schedule or spot control
• Sauna — midday or weekends
• Dishwasher and dryer — at night

Where can I see the spot price?

• Provider apps (Fortum, Hehku Energia, Oomi)
• Sähkönhinta.fi
• Fingrid Datahub
• Smart-home apps (Tibber, Spotti)

Spot risks and how to manage them

• Price lock — Fortum service to fix the spot margin
• Hybrid contract — Fortum Duo (50 % fixed / 50 % spot)
• Consumption flexibility — avoid heavy use at peak hours
