The suppliers will be informed in due time should it be necessary to postpone or change the bidding period in exceptional circumstances.

Award procedure

At the end of the bidding period the offered aFRR capacity bids are ranked according to the following criteria:

  1. Lowest capacity price

     

  2. In case of equal capacity prices: Lowest energy price for positive aFRR, highest energy price for negative aFRR
  1. In case of equal capacity and energy prices: earlier bid time stamp

Suppliers whose bids are selected receive the stated aFRR capacity price, i.e. a "pay as bid" approach is used. Once the bid has been selected, the suppliers are obliged to keep the corresponding volume of aFRR available for activation. Changes in the award procedure will be published at least 14 days before they enter into force.

Unsuccessful Tenders

In the event of an unsuccessful tender, e.g. in case not enough capacity is offered, the valid bids will be accepted and a second tender will be opened for the shortfall. If, after the second tender, a shortfall remains, a further invitation to tender will be opened in a "last call". In this case, APG calls on the suppliers to offer available power via e-mail or, if possible, via telephone. In the event that the "last call" still does not suffice to cover the shortfall, APG has the right to oblige suppliers to provide the aFRR (obligation to supply). Detailed information regarding this procedure can be found in the Tendering Conditions for aFRR (German only).
