Method for determining the reBAP

The imbalance pricing system applied to balance responsible parties' imbalances has the following characteristics:

  • Imbalance prices are calculated for each balancing interval (equivalent to the scheduling interval of hour). Since 01/06/2010, a uniform balancing energy price (reBAP) applies for the whole of Germany.
  • The balancing energy prices are based on the TSO's payments or proceeds for the activated control energy (secondary and minute reserve).
  • Symmetric price per hour, i.e. no price spread between positive and negative balance group deviations.
  • Due to the introduction of negative energy prices for minute and secondary control reserves, the balancing energy price can also be negative and therefore also cause costs for balancing groups with a positive imbalance.

The German transmission system operators (TSOs) will implement the decision of the Federal Network Agency (FNA) for the development of the balancing energy price settlement system (BK6-12-024) as of 01/12/2012. Substantial changes to the current system are the link between the reBAP and the quoted price, and the fact that in case 80 % of the control energy under contract in Germany is exceeded, either a surcharge or a deduction is applied to the balancing energy price, depending on the negative or positive value of the balance of activated control energy.

The detailed calculation method of the single price for balancing energy for all control areas (reBAP) was published by the TSOs in accordance with the decision of the FNA in the following document:
