BRPs are required to provide a financial guarantee to mitigate the risk of unpaid invoices and to ensure active portfolio balancing. The guarantee amount is determined as the maximum of two components: the invoice-based risk guarantee and the position-based risk guarantee.
The invoice-based risk guarantee is a weighted average of the invoice amounts from the last three months, with increased emphasis on the most recent month. Credit notes are also deducted from the required value.
The position-based risk guarantee reflects the market’s current conditions, using the average imbalance price of the last month (with a minimum value of 50 EUR/MWh and a minimum considered position of 50MW) and covering 12 hours of 100% imbalance in line with the day-ahead balance obligation.
This approach ensures a robust and fair financial framework for both Elia and BRPs.
BRP’s position for its initial months of the Contract is determined by mutual agreement between the Parties, based on BRP’s estimated highest position for the coming three months. This value will form the basis for determining the initial amount of the guarantee.
In all cases, the minimum guarantee is always 30.000 EUR. As invoices and historical position data become available, the financial guarantee will be evaluated and updated as necessary.
Note: this methodology to determine the financial guarantee entered into force on February 27th, 2026.
