Which is better, Yleissiirto or Yösiirto?
In our calculation Yleissiirto is cheapest for a detached house without electric heating and Yleissiirto with direct electric heating. Night and seasonal products pay off when consumption moves to the night, for example with storage heating or a hot-water tank. Check your own hourly consumption in Fingrid’s Datahub.
Can I switch my network company?
No. Transmission is always handled by the network company in your area, which bills transmission and electricity tax separately. You can only put the electricity contract, the energy itself, out to tender. You can usually change transmission product within the same company once a year.
How much is the electricity tax?
Household electricity tax (tax class I) is 2.918 c/kWh including 25.5 % VAT. It includes the security-of-supply fee and is the same with every network company.
Which electricity contract is cheapest for you?
Transmission does not depend on the seller. Compare contracts and see the total price with transmission.
