Who is Fortum Duo 12 kk for?
A hybrid contract suits the consumer who wants a balance between stability and market sensitivity. You get partial protection from expensive winter hours (the fixed part keeps the bill reasonable) but also benefit from cheap summer spot hours (the spot part lowers the bill). A good choice for mid-usage households (row houses, semi-detached) with no strong preference for pure spot or pure fixed.
Pros and cons
Pros
- Balanced solution: partly locked, partly market-sensitive
- Cushions the worst winter spikes while still benefiting from market drops
- Suitable for a broad range of consumers with no special requirements
- Clearer than pure spot but cheaper than fully fixed
Cons
- May be more expensive than pure spot over the long term
- Pricing is more complex — read the contract terms carefully

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.
