Due to the multitude of balancing groups and their deviations, the occurring energy flows are counterbalanced. Only the remainder, i.e. the balance of all balancing group deviations (grid area balance), makes it necessary to use the procured balancing energy. The resulting costs are transferred to the balancing groups through the balancing group settlement.
The basis for the market communication prior to settlement is the presentation of a valid certificate. The process for balancing group settlement is laid down in the market rules for the balancing group settlement for electricity (MaBiS). This also determines the data exchange deadlines for the preparation of the settlement.
Uniform model to determine a standard cross-grid area balancing energy price (reBAP)
The standard cross-grid area balancing energy price (reBAP) applies to all German grid areas since May 2010.
In addition to the reBAP, the relevant balance of the used grid energy is also mentioned for each quarter-hour of the grid areas participating in the GCC (GCC balance). A plus sign corresponds to the purchase of positive grid energy due to deficient coverage of grid areas whereas a negative sign corresponds to the purchase of negative grid energy (delivery of surplus energy) in case of excess cover of the affected grid areas.
Costs and revenues from balancing group settlements
Pursuant to the resolution BK6-12-024 of the Federal Network Agency of 25/10/2012 and the associated description of the model to calculate the reBAP, the costs of the balancing energy used to balance the grid area, the revenues from the balancing group settlement, the revenue surplus for the reduction of grid charges and the further allocation of higher/lower revenues are presented on a delta account. The delta account consists of corrections referring to the past, resulting e.g. from belated claims of balancing energy suppliers that could not yet be cleared at the time of the reBAP publication.
