For Dispatchable Generating Units and Pumped Storage Dispatchable Hydroelectric Generating Units, the ISP Balancing Energy Offers per Dispatch Period are automatically converted into equivalent 15-minute mFRR and aFRR Energy Market Offers. Each ISP Balancing Energy Offer per Dispatch Period shall be converted into two (2) equivalent 15-minute Balancing Energy Offers for mFRR and aFRR, in the same form and for the same Balancing Energy volumes and prices as those in the original offer. These automatically created Offers shall be deemed as submitted by the Participant and shall produce all the results provided for in this Rulebook, as if the Offers had been submitted by the Participant.

The price of the Balancing Energy Offers for mFRR and aFRR submitted pursuant to paragraph 1 of this Article by Balancing Service Providers representing Dispatchable Generating Units, including Dispatchable Hydro Generation Units with pumped storage capability, must be an improved price in relation to the ISP Balancing Energy Offer submitted to the ISP for the Dispatch Period which includes the mFRR Time Unit. The term improved price means a lower price for upward Balancing Energy Offers and a higher price for downward Balancing Energy Offers. The price of the Balancing Energy Offers for mFRR and aFRR submitted pursuant to paragraph 1 of this Article by Balancing Service Providers representing Dispatchable Generating Units, including Dispatchable Hydro Generation Units with pumped storage capability, cannot be changed in relation to the volume of the ISP Balancing Energy Offer submitted to the ISP for the Dispatch Period which includes the mFRR Time Unit.

For the Dispatchable RES Units Portfolios and the Dispatchable Load Portfolios after each ISP, for each Dispatch Period until the end of the Dispatch Day for which there is a corresponding obligation, in accordance with Article 14.5, the ISP Balancing Energy Offers shall be automatically converted into corresponding 15-minute mFRR and aFRR Energy Market Offers and shall replace any other currently valid offers. Each ISP Balancing Energy Offer per Dispatch Period shall be converted into two (2) equivalent 15-minute mFRR and aFRR Energy Market Offers with the same Balancing Energy prices and a volume corresponding to the sum of the volumes of Balancing Energy awarded under the ISP, together with the volume of Balancing Energy corresponding to the Balancing Capacity for mFRR or aFRR supply awarded under the ISP.

The term improved price means a lower price for upward Balancing Energy Offers and a higher price for downward Balancing Energy Offers. The volumes of mFRR and aFRR Balancing Energy Offers submitted pursuant to paragraph 1 of this Article by Balancing Service Providers representing Dispatchable Load Portfolios, and Dispatchable RES Units Portfolios may not be reduced for the Dispatch Period that includes the mFRR Time Unit in relation to the sum of the volumes of Balancing Energy awarded under the ISP and the volumes of Balancing Energy corresponding to the Balancing Capacity for the provision of mFRR and aFRR awarded under the ISP.
