Tenders for mFRR in the APG Control Area

This page contains the most important information for potential suppliers of manual frequency restoration reserve (mFRR). More precise and legally binding information can be found in the contract documentation in the Download column.

 

Tendering platform

The tender takes place exclusively via the electronic tendering platform.

 

Awarding Procedure

  1. Power price (€/MWh)

  2. In case of equal bid price (€/MWh):

    - Lowest energy price (pos. mFRR)
    - Highest energy price (neg. mFRR)

  3. In case of equal power price and energy price: earlier bid time stamp

 

Suppliers whose bids 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 mFRR.

 

Activation and Ranking of Balancing Energy

  1. Energy price (€/MWh)

    - Lowest energy price (pos. mFRR)
    - Highest energy price (neg. mFRR)

  2. In case of equal energy price: lowest power Price

  3. In case of equal energy price and power price: earlier bid time stamp

 

mFRR is only provided when called by APG. It must then be provided for a minimum of 15 minutes. This minimum period does not, however, apply up to the end of the product time slot, as, in this case, the call and the product time slot end at the same time (compare item 3(7) of the Framework Agreement - in German).

 

All callable bids for the provision of mFRR are ranked according to the criteria above and entered in the merit order list. In the event that it is necessary to increase or reduce the generation capacity in the APG control area, the next offer in the list will be called. Accepted suppliers receive the price they bid in euro per megawatt hour (when delivering energy) or pay the price they bid (when taking energy from the grid).

 

Unsuccessful tender

In the event of an unsuccessful tender, e.g. not enough bids, the valid bids will be accepted and a new tender (second call) 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.

Detailed information relating to this procedure can be found in Tendering Conditions for mFRR (German only).
