Tendered Volume

mFRR balancing capacity required in the APG control area currently amounts to +280 MW (positive mFRR) and -195 MW (negative mFRR), which are procured in daily capacity tenders. The dimensioning of the mFRR control reserve to be tendered can be changed by the control area manager if necessary.

The tender takes place exclusively via the electronic tendering platform of APG

Capacity Tenders

When do the tenders take place?

The required mFRR control reserve in Austria is tendered on a daily basis (calendar days, from Monday to Sunday). The most important deadlines for a tender are summarised in the following table:

The following figure also shows the sequence for an entire delivery week:

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 mFRR capacity bids are ranked according to the following criteria:

  1. lowest capacity price

  2. if the prices for capacity are the same, the award of the contract will be based on an algorithm for reproducible randomization 

Market participants, whose bids are selected, receive the quoted mFRR capacity price, i.e. a "pay as bid" approach is used. The energy prices submitted in the capacity tender will be carried over to the energy tender and may be adjusted (downwards and upwards) until the end of the energy tender period.

Possible future changes in the award procedure will be announced with a lead time of at least 14 days. 

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 there is still a shortfall after the second tender, a further invitation to tender will be opened in a "last call". In this case, APG calls on potential 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 mFRR (obligation to supply). Detailed information regarding this procedure can be found in the Tendering Conditions for mFRR (German only).

Energy Tenders

When do the tenders take place?

The required mFRR balancing energy is put out to tender intraday (from Monday to Sunday). Bids can be submitted and adjusted from the successful completion of the capacity tender until one hour before the delivery period of the respective product. The most important deadlines of the tender are summarised in the following table:

The market participants 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 mFRR energy bids are ranked according to the following criteria:

  1. lowest energy price for positive mFRR or highest energy price for negative mFRR;

  2. if the prices for energy are the same, the award of the contract will be based on an algorithm for reproducible randomization.

 

Market participants, whose bids are selected, receive the quoted mFRR energy price, i.e. a "pay as bid" approach is used. Once a bid has been accepted, the provider is obliged to keep the accepted quantity available for activation at any time.

Possible future changes in the award procedure will be announced with a lead time of at least 14 days.

There is no splitting of the bids in the call-up.

Backup procedure

If the process of energy tendering cannot be fully completed for technical reasons, all bids submitted up to that point will lose their validity. Backup energy prices are calculated for the creation of the merit order list.

The calculation of the backup energy prices for delivery day D are carried out for each provider and product based on the energy bids the provider submitted for the 14 delivery days before the Gate Closure Time of the capacity tender (D-1). The calculation steps for delivery day D are as follows:

  • Sorting the bids of each provider per product

    • The energy bids for delivery days D-15 to D-2 are sorted according to the energy price (ascending for positive mFRR, descending for negative mFRR) and, in case of equality, ascending according to the size of the energy bid.

    • The capacity bids for delivery day D are sorted in ascending order by capacity price and, in the case of equality, by energy price (ascending for positive mFRR, descending for negative mFRR) and time stamp (ascending).


  • Generation of an average 1-MW-MOL

    • The average price for the first MW, the second MW, etc. is calculated based on the energy prices submitted.

    • This MOL must then be sorted again (ascending for positive mFRR, descending for negative mFRR).


  • Calculation of the backup energy price MOL

    • The backup energy prices are calculated based on the 1-MW-MOL and the quantities of the bids submitted in the capacity tenders for the relevant delivery day D.

    • The backup energy price of a bid is calculated as the average value of the prices from the 1-MW-MOL corresponding to the quantities of the submitted balancing capacity bids.

 

Two special cases can occur regarding the calculation:

  • The supplier has not submitted any valid energy price for one or more products within the last 14 calendar days before the delivery date. As a substitute, the 1-MW-MOL for this provider is calculated as the average of the 1-MW-MOLs of all other tenders.

  • The quantity offered for a product in the respective capacity tender exceeds that of the last 14 delivery days and thus also the length of the 1-MW-MOL. In this case, the last backup energy price is applied for all subsequent MWs
