To change the price, select Tariffs on the left-hand menu and click the edit button after selecting the tariff you want to change.
The image below shows the edit button:

When editing the tariff, select Pricing and simply change the number under Fee per kWh. The amount is entered in NOK, including VAT.
Example: The charging price is 2 NOK. Enter 2 to set the correct price. If you want to include øre in the price, write the kroner amount followed by a comma and the øre amount (example: 2,35 NOK).

If you want to switch to a spot price tariff, see the article “What is spot price and how do I create them?”
