It is the collateral to be provided in order to have a long or short position in the futures electricity market in the financial period. The contract margin is calculated as follows:

Where,

• It is calculated only for contracts within the financial period.
• At the end of the session, if there is no GGF, the most recent AF is used.
• The most up-to-date AF is used during the session.
• If a base price tender is held for contracts to be traded for the first time, the bid prices and amount are used.
