Article 19.3 Calculation of Balancing Energy debits and credits

The debits or credits to the Balancing Service Providers for each Balancing Service Entity they represent, per Imbalance Settlement Period, for activated Balancing Energy for mFRR following a relevant Dispatch Instruction shall be determined for each direction according to the following table:

	Positive Balancing Energy Price	Negative Balancing Energy Price
Upward Balancing Energy	Payment from Clearing House to Balancing Service Provider	Payment from Balancing Service Provider to Clearing House
Downward Balancing Energy	Payment from Balancing Service Provider to Clearing House	Payment from Clearing House to Balancing Service Provider

The charge or credit of the Balancing Services Providers for each Balancing Service Entity that they represent per each Imbalance Settlement Period, for the activated mFRR Balancing Energy, including the activated Balancing Energy for mFRR Test Dispatch Instructions, is calculated as follows:

a) For the activated upward mFRR Balancing Energy:

$A B E C_{e, t}^{m F R R, u p} = A B E_{e, t}^{m F R R, u p} \times B E P_{z, t}^{u p}$

Where:

$A Β E C_{e, t}^{m F R R, u p}$	The debit or credit in € for the activated upward Balancing Energy for mFRR for a Balancing Service Entity e and an Imbalance Settlement Period t.
$A B E_{e, t}^{m F R R, u p}$	The activated upward Balancing Energy for aFRR for a Balancing Service Entity e and an Imbalance Settlement Period t.
$B E P_{z, t}^{u p}$	The clearing price of an upward mFRR, of the Bidding Zone, z, in €/MWh to which the Balancing Services Entity e belongs.

b) For the activated downward mFRR Balancing Energy:

$A B E C_{e, t}^{m F R R, d n} = A B E_{e, t}^{m F R R, d n} \times B E P_{z, t}^{d n}$ .

Where:

$A Β E C_{e, t}^{m F R R, d n}$	The debit or credit in € for the activated upward Balancing Energy for mFRR for a Balancing Service Entity e and an Imbalance Settlement Period t.
$A B E_{e, t}^{m F R R, d n}$	The activated downward Balancing Energy for mFRR in MWh for a Balancing Service Entity e and an Imbalance Settlement Period t.
$B E P_{z, t}^{d n}$	The clearing price of a downward mFRR, of the Bidding Zone, z, in €/MWh to which the Balancing Services Entity e belongs.

The charge or credit of the Balancing Service Providers for the activated upward aFRR Balancing Energy, and for each Balancing Service Entity e that they represent, is calculated per Imbalance Settlement Period t as the sum of the respective charges or credits for each minute i within the Imbalance Settlement Period t. The above charges or credits shall be calculated as follows:

$A B E C_{e, t}^{α F R R, u p} = \sum_{i = 1}^{15} (A B E_{e, i}^{a F R R, u p} \times S P_{e, i}^{a F R R, u p})$

Where:

$A B E C_{e, t}^{α F R R, u p}$	the debit or credit for the activated upward aFRR Balancing Energy for a Balancing Service Entity e and an Imbalance Settlement Period t.
$A B E_{e, t}^{α F R R, u p}$	The upward activated aFRR Balancing Energy in MWh for the Balancing Services Entity e during one minute i within the Imbalance Settlement Period t.
$S P_{e, i}^{a F R R, u p}$	The upward aFRR clearing price for the Balancing Services Entity e during one minute i within the Imbalance Settlement Period t.

The charge or credit of the Balancing Service Providers for the activated downward aFRR Balancing Energy, and for each Balancing Service Entity e that they represent, is calculated per Imbalance Settlement Period t up to the sum of the corresponding charges or credits for each minute i within the Imbalance Settlement Period t. The above charges or credits shall be calculated as follows:

$A B E C_{e, t}^{α F R R, d n} = \sum_{i = 1}^{15} (A B E_{e, i}^{a F R R, d n} \times S P_{e, i}^{a F R R, d n})$

Where:

$A B E C_{e, t}^{α F R R, d n}$	the debit or credit for the activated upward aFRR Balancing Energy for a Balancing Service Entity e and an Imbalance Settlement Period t.
$A B E_{e, t}^{α F R R, d n}$	The downward activated aFRR Balancing Energy in MWh for the Balancing Services Entity e during one minute i within the Imbalance Settlement Period t.
$B E P_{z, t}^{d n}$	The downward aFRR clearing price for the Balancing Services Entity e during one minute i within the Imbalance Settlement Period t.
