With Delivery Day 12 July 2018 (Tender Date 11 July 2018), the aFRR products in Austria are converted to six 4-hour blocks per day for delivery and purchase.
New products (starting 12 July 2018)
The aFRR needed in the APG control area currently amounts to +/-200 MW procured in weekly and daily tenders.
In exceptional circumstances, the required volume of aFRR can be changed by the control area manager.
The minimum bid is 5 MW. Bids in excess of the minimum bid can be placed in full 1 MW increments but must not, however, exceed the pre-qualified power.
The tenders take place exclusively via the electronic tendering platform.
As part of the conversion, the tendering periods will also be adjusted. Thus, the required SRR in Austria is tendered on a calendar daily basis (from Monday to Sunday). This also gives rise to new dates for the Gate Open and Gate Closure of the call for tenders and the publication of the tender results.
The corresponding times are summarized in the following table:
Gate Open of SRR tender for delivery day D
Gate Closure of SRR tender for delivery day D
Publication of results of SRR tender for delivery day D
The following graphic also shows the process for a delivery week:
The suppliers will be informed in due time should it be necessary to postpone or change the bidding period in exceptional circumstances.
At the end of the bidding period the bids are ranked according to the following criteria and the contracts are awarded:
Suppliers whose offers are successful will receive the power price they quoted, i.e. a "pay as bid" approach is adopted. Once the bid has been accepted, the suppliers are obliged to reserve the corresponding volume of aFRR.
Factors for quarter Q3/2019, valid from 1 July 2019 to 30 September 2019 are:
aFRR is called on the basis of an automatic, continuously defined power setpoint which is forwarded to the supplier by the secondary controller at APG.
In the event of an unsuccessful tender, e.g. not enough bids, the valid bids will be accepted and a new tender will be opened for the shortfall.
If there is still a shortfall after the second invitation to tender, a further invitation to tender will be opened in a "last call". In this case, APG calls on the suppliers to offer available power by e-mail or if possible, by telephone.
In the event that an insufficient volume of aFRR is still not available after the "last call", APG has the right to oblige suppliers to make available and provide the aFRR (obligation to supply).
Detailed information relating to this procedure can be found in the Tendering Conditions for aFRR (German only).
