Article 19.2 Manual FRR and Automatic FRR Clearing Prices

The clearing prices of mFRR and aFRR are calculated in €/MWh.
If there is no congestion between Bidding Zones, the upward Balancing Energy Price for mFRR, $B E P_{z, t}^{u p}$ , for each Imbalance Settlement Period, t, for the activation of upward mFRR Balancing Energy shall be equal to the maximum Balancing Energy Offer prices for the mFRR steps that were activated to cover the HETS Imbalances. In the event there is congestion between the Bidding Zones, the clearing price for upward mFRR for each Imbalance Settlement Period, t, for activation of upward Balancing Energy for each Bidding Zone is equal to the maximum prices of the mFRR Balancing Energy Offer steps that were activated to cover the imbalance in the specific Bidding Zone, z.
If there is no congestion between Bidding Zones, the downward mFRR clearing price (in EUR/MWh), $B E P_{z, t}^{d n}$ , for each Imbalance Settlement Period, t, for the activation of downward mFRR Balancing Energy is equal to the minimum Balancing Energy Offer prices for the mFRR steps that were activated to cover the HETS Imbalances. If there is congestion between the Bidding Zones, the clearing price for downward mFRR for each Imbalance Settlement Period, t, for activation of downward Balancing Energy for each Bidding Zone is equal to the minimum prices of the mFRR Balancing Energy Offer steps that were activated to cover the imbalance of the specific Bidding Zone, z.
The upward and downward Balancing Energy Offers for mFRR activated for purposes other than balancing shall be marked and excluded from the calculation of upward and downward clearing prices for mFRR. The activation purposes which fall into the category of “purposes other than balancing” shall be defined in the methodology for classifying the activation purposes of Balancing Energy Offers in accordance with Article 29(3) of
Regulation (EU) 2017/2195.
The upward and downward Balancing Energy Offers for mFRR for the Balancing Service Entities and for the Imbalance Settlement Periods which are set out in the ‘Calculation Methodology for Unfeasible Market Schedule’ shall be marked and excluded from the calculation of upward and downward mFRR clearing prices.
Upward and downward mFRR Balancing Energy Offers for the Balancing Service Entities and for Imbalance Settlement Periods that are activated for Test Dispatch Instruction purposes shall be marked and excluded from the calculation of upward and downward mFRR clearing prices.
If the calculation of the mFRR and aFRR clearing prices is impossible, in particular due to an Emergency Situation, or failure of the Balancing Market System or of the other electronic systems of the HETS Operator, the HETS Operator shall apply the procedure provided for in the ‘Rules for settlement in case of suspension of market activities’.

The aFRR Clearance Price shall be derived per Balancing Services Entity, for each minute i of the Balance Settlement Period t, according to the direction of the Balancing Action activated, as follows:

a) To activate upward aFRR Balancing Energy:

$S P_{e, i}^{a F R R, u p} = m a x (S P_{W A E, i}^{a F R R, u p}, O P B E_{e, s, i}^{a F R R, u p})$

Where:

$S P_{W A E, i}^{a F R R, u p}$	The weighted clearing price of upward aFRR in €/ MWh for minute i, in accordance with paragraph 9 of this Article.
$O P B E_{e, s, i}^{a F R R, u p}$	The price of step s of the Balancing Energy Offer for upward aFRR of the Balancing Services Entity corresponding to the activated upward aFRR energy calculated for minute i, in accordance with the ‘Activated Energy Calculation Methodology’.

b) To activate downward aFRR Balancing Energy:

$S P_{e, i}^{a F R R, d n} = m i n (S P_{W A E, i}^{a F R R, d n}, O P B E_{e, s, i}^{a F R R, d n})$

Where:

$S P_{W A E, i}^{a F R R, d n}$	The weighted clearing price for downward aFRR in €/MWh for minute i, in accordance with paragraph 10 of this Article.
$O P B E_{e, s, i}^{a F R R, d n}$	The price of step s of the Balancing Energy Offer for downward aFRR of the Balancing Services Entity corresponding to the activated upward aFRR energy calculated for minute i, in accordance with the ‘Activated Energy Calculation Methodology’.

The weighted clearing price for upward aFRR shall be calculated for each minute i of the Balance Settlement Period t as follows:

$S P_{e, i}^{a F R R, u p} = \frac{\sum_{c \in i} (R E_{c}^{a F R R, u p} \times M P_{c}^{a F R R, u p})}{\sum_{c \in i} (R E_{c}^{a F R R, u p})}$

Where:

$c$	The AGC cycle.
$M P_{c}^{a F R R, u p}$	The weighted clearing price of upward aFRR in €/ MWh for AGC cycle c, in accordance with paragraph 11 of this Article.
$R E_{c}^{a F R R, u p}$	The required activation of upward aFRR Balancing Energy served locally in MWh for each AGC cycle c during minute i, with a positive value.

The weighted settlement price for downward aFRR shall be calculated for each minute i of the Balance Settlement Period t as follows:

$S P_{e, i}^{a F R R, d n} = \frac{\sum_{c \in i} (R E_{c}^{a F R R, d n} \times M P_{c}^{a F R R, d n})}{\sum_{c \in i} (R E_{c}^{a F R R, d n})}$

Where:

$c$	The AGC cycle.
$M P_{c}^{a F R R, d n}$	The weighted clearing price for downward aFRR in an AGC cycle (in €/MWh) for AGC cycle c, in accordance with paragraph 11 of this Article.
$R E_{c}^{a F R R, d n}$	The required activation of downward aFRR Balancing Energy served locally in MWh for each AGC cycle c during minute i, with a positive value.

For the periods of time that the HETS Operator remains connected to the European aFRR Platform, the upward and downward aFRR clearance price in an AGC cycle shall be the same as and equal to the Cross-Border aFRR Clearance Price sent by the European aFRR Platform. For periods of time when the HETS Operator remains disconnected from the European aFRR Platform, the upward aFRR clearing price of the AGC cycle corresponds to the highest price of all upward aFRR Balancing Energy Offers that were activated from the local aFRR merit order list, while the downward aFRR clearing price of the AGC cycle corresponds to the lowest price of all downward aFRR Balancing Energy Offers that were activated from the local aFRR merit order list.
If the calculation of the mFRR and aFRR clearing prices is impossible, in particular due to an Emergency Situation, or failure of the Balancing Market System or of the other electronic systems of the HETS Operator, the HETS Operator shall apply the procedure provided for in the ‘Rules for settlement in case of suspension of market activities’.
