Procedure for Ex Post Settlement

1. Who can request ex post settlement?

Ex post settlement can only be requested by the party responsible for the data, and the invoice for the costs incurred is sent exclusively to said party (see Data Services).

The application form is available here; it must be sent fully completed by regular mail or fax to APCS (+43 1 3190701-70).

2. Why can ex post settlement be requested?

In the event that balance group aggregate, grid transfers or schedules were not sent or sent with faults, the corrected data may be transmitted and an ex post settlement requested.

3. Who must be informed of ex post settlement?

Before the corrected data for ex post settlement can be sent to APCS, the party which is responsible for the data must contact the respective balance groups, specifically also with those balance groups that settle grid losses with in the grids concerned.

4. When must the data for ex post settlement be sent?

After sending the application for ex post settlement, the data as well as information on the concerned market participants (see Item 3.) may be sent at any time to APCS irrespective of whether a date has been fixed for ex post settlement or not; the data are “parked” until APCS carries out ex post settlement.
Furthermore, the data must be made available to the concerned market participants. It is important for the internal settlement of the concerned market participants to use the same database as APCS, as otherwise it would not be possible to check the correctness of the settlement.

5. How does the billing work?

Once the time of the ex post settlement is fixed, APCS informs the concerned market participants by sending an e-mail to the administrative and technical contact persons. The ex post settlement considers only the components mentioned in the application for ex post settlement. The concerned balance groups receive a new invoice on which the difference in the amounts between the old and the new settlement is stated that is credited or debited to the account. Moreover, the party requesting the ex post settlement receives an invoice for the costs of the ex post settlement.
