Who is Fortum Tarkka – Pörssisähkö for?
A spot contract is well suited to households that can shift consumption to cheap spot hours. The cheapest hours are typically overnight and early morning — charging an EV, running the dishwasher or heating the sauna during cheap hours can deliver meaningful savings. Over the long term, spot pricing is often the cheapest choice, but in the winter months the price can spike temporarily, so be prepared for variation in your monthly bill.

Good to know before ordering
Pricing and contract details. The prices, monthly fees, intro offers and terms shown here are based on the provider's own information and may change without notice. Promotional offers run for a limited time, and intro benefits typically apply only to new customers. The final price is confirmed in the provider's contract confirmation — verify the contract details from the provider before ordering.
What the prices include. The prices cover electricity energy only, not the local grid operator's electricity transmission. On spot-price contracts the final price varies with the Nord Pool market price by the hour or quarter-hour. The Verrokit comparison tool's monthly estimate is indicative and based on your annual consumption and a Nord Pool average assumption — your actual monthly bill may differ.
Verrokit's role. Verrokit is not a contracting party — the contract is between the consumer and the electricity provider. Verrokit operates as a comparison service and earns a partner commission on some contracts when the user clicks through the "Choose" button. The commission does not affect the price visible to the consumer. The comparison order is based on price data, not on partner relationships. Verrokit is not responsible for individual price changes, errors in data, or interpretation of contract terms.
