Details of how to submit Balancing Capacity Offers to ISP are described in the Technical Decision “Integrated Scheduling Process”.

The Balancing Capacity Offers for each Balancing Service Entity and for each Dispatch Period shall consist of individual steps and shall refer to all types of Balancing Capacity for which their Balancing Service Entities have the required technical capacity as per their Registered Characteristics. Each step shall contain the price of the Balancing Capacity Offer in €/MW - hour, accurate to two (2) decimal places, and the quantity of the Balancing Capacity Offer in MW, accurate to one (1) decimal place. 

The minimum quantity of the Balancing Capacity Offer shall be equal to one (1) MW. 

The upward Balancing Capacity Offer shall include between one (1) and ten (10) steps. The Balancing Capacity Offer price for each successive step may not be reduced in relation to the price of the Offer for the preceding step.

The downward Balancing Capacity Offer shall include between one (1) and ten (10) steps. The Balancing Capacity Offer price for each successive step may not be reduced in relation to the price of the Offer for the preceding step.

Balancing Capacity Offers for each Dispatch Period of a Dispatch Day shall be submitted separately for upward and downward FCR Balancing Capacity, for upward and downward aFRR Balancing Capacity and for upward and downward mFRR Balancing Capacity. The price for each step of the above offers shall be greater or equal to the Balancing Capacity Offer Minimum Price and less than or equal to the Balancing Capacity Offer Maximum Price for each type of reserve.

The numerical values of the Balancing Capacity Offer Minimum Price and the Balancing Capacity Offer Maximum Price are specified in the Technical Decision “Technical limits on bidding and clearing prices in the Balancing Market”. This Technical Decision shall be issued at least two (2) months prior to the date of enforcement of the new values of the above limits.

In the event that a Balancing Capacity Offer is not submitted in accordance with Article 11.1 and Article 11.2, the Balancing Capacity Offer for all Dispatch Periods of the Dispatch Day shall be automatically rejected by the Balancing Market System. In that case, the grounds for the rejection shall be notified to the Balancing Service Providers through the Balancing Market System. The Balancing Service Provider may re-submit a Balancing Capacity Offer until the Expiration Date for Submission of Offers to the ISP. If the Balancing Capacity Offer is submitted in accordance with Article 11.1 and Article 11.2, the Balancing Capacity Offer shall be validated. Only the last validated Balancing Capacity Offers shall be taken into consideration for the execution of the ISP.

In case the Balancing Service Providers representing Dispatchable RES Units Portfolios or Dispatchable Load Portfolios do not submit Balancing Energy Offers for a quantity that corresponds at least to the offered quantity of Balancing Capacity for a Dispatch Period, the Balancing Capacity offers for the respective Dispatch Period shall be automatically rejected by the Balancing Market System.

After the Expiration Date for Submission of Offers to the ISP, Balancing Capacity Offers may not be modified and shall be used as-is for resolution of the Integrated Scheduling Processes of ISP1, ISP2, ISP3, and any other ISP requirement.

In case of non-submission or non-acceptance of Balancing Capacity Offers for a Dispatch Day in connection with a Balancing Service Provider that is obliged to submit a Balancing Capacity Offer in accordance with Article 11.1, the Balancing Market System shall automatically create Balancing Capacity Offers for the respective Dispatchable Generating Unit and for all Dispatch Periods of the Dispatch Day, establishing prices equal to the corresponding prices included in the last validated Balancing Capacity Offer of the previous day. The Offers which are created automatically by the Balancing Market System shall be considered as having been submitted by the Participant and shall produce all the results provided for in this Rulebook, as if these Offers had been submitted by the Participant.
