The minimum collateral is equal to NOK/SEK/DKK 240.000,- of EUR 30.000,- and posted security covers both Elspot and Elbas markets. The current basis for collateral calculation is each individual participants trading in the past. Currently the collateral requirement is equal to the last seven days purchases, including VAT, excluding trading fees. Norway is currently the only area being invoiced including VAT. For all other areas partipants are themselves responsible for VAT settlement. The collateral requirement is including the minimum collateral, not on top of the minimum collateral. The collateral call on the two markets are netted daily according to the invoice date. 

For participants who only acts as sellers the collateral requirement will always be equal to the minimum collateral requirement.

For participants who only acts as buyers the collateral requirement will be equal to the last seven days purchases including VAT, or at least the minimum collateral.

Participants who from time to time move from seller to buyer, or the other way, need to take special care. The rules are such that if you have been a buyer for atleast one day within the last seven days, a seven day collateral call will be calculated. If the participant continues to buy, the collateral call will be adjusted daily, in order to simulate a seven days purchase. If the participant switches to selling, it will take seven continuous days before the collateral requirement is reduced to the minimum.

The rulebook also contain important collateral information.
