CHAPTER 20 BALANCING CAPACITY SETTLEMENT

Article 20.1 Calculation of the supplied quantity of Balancing Capacity

The Balancing Capacity Settlement Period is set to be equal to the Imbalance Settlement Period. In order to ensure that the ISP Dispatch Period corresponds with the Imbalance Settlement Periods, the half-hourly results for ISP Balancing Capacity shall be divided into two (2) equivalent 15-minute results.
For each Balancing Service Entity and for each Imbalance Settlement Period, the upward and downward Balancing Capacity supplied for FCR, aFRR and mFRR shall be calculated taking into account:
1) The segments of the individual steps of the Balancing Capacity Offer that have been validated on the basis of the last ISP execution, whose solution timeframe shall include that specific Imbalance Settlement Period.
2) the availability in MW of the Balancing Service Entity for the provision of the service in real time.
3) the percentage of a time period within an Imbalance Settlement Period when the Balancing Service Entity was available for the provision of FCR in real time.

The upward and downward Balancing Capacity provided for FCR by a Balancing Service Entity e for an Imbalance Settlement Period t shall be calculated as follows:
$F C R Q_{e, t}^{u p} = \sum_{s}^{} \sum_{a s}^{} (F C R Q_{e, a s, t}^{u p}) \times T_{e, t}^{F C R, u p}$
$F C R Q_{e, t}^{d n} = \sum_{s}^{} \sum_{a s}^{} (F C R Q_{e, a s, t}^{d n}) \times T_{e, t}^{F C R, d n}$

where:

$F C R Q_{e, t}^{u p}$	the upward FCR Balancing Capacity, in MW, supplied by the Balancing Services Entity e for the Imbalance Settlement Period t.
$F C R Q_{e, a s, t}^{u p}$	the segment, as, of step, s, in MW of the upward FCR Balancing Capacity Offer validated by the Balancing Services Entity, e, for the Dispatch Period which includes the Imbalance Settlement Period, t, based on the latest execution of the ISP, the resolution time horizon of which includes the specific Imbalance Settlement Period t.
$T_{e, t}^{F C R, u p}$	the percentage of a time period within an Imbalance Settlement Period t when the Balancing Service Entity e was available for the provision of upward FCR in real time.
$F C R Q_{e, t}^{d n}$	the upward Balancing Capacity for FCR, in MW, supplied by the Balancing Services Entity e for the Imbalance Settlement Period t,
$F C R Q_{e, a s, t}^{d n}$	the segment, as, of step, s, in MW of the upward FCR Balancing Capacity Offer validated by the Balancing Services Entity, e, for the Dispatch Period which includes the Imbalance Settlement Period, t, based on the latest execution of the ISP, the resolution time horizon of which includes the specific Imbalance Settlement Period t.
$T_{e, t}^{F C R, d n}$	the percentage of time in an Imbalance Settlement Period tduring which the Balancing Service Entity e was available for the provision of downward FCR in real time.

The upward and downward Balancing Capacities for mFRR supplied by a Balancing Service Entity e for an Imbalance Settlement Period t shall be calculated as follows:
$m F R R Q_{e, t}^{u p} = \sum_{s}^{} \sum_{a s}^{} (m F R R Q_{e, a s, t}^{u p}) \times T_{e, t}^{m F R R, u p}$
$m F R R Q_{e, t}^{d n} = \sum_{s}^{} \sum_{a s}^{} (m F R R Q_{e, a s, t}^{d n}) \times T_{e, t}^{m F R R, d n}$

where:

$m F R R Q_{e, t}^{u p}$	the upward Balancing Capacity for mFRR, in MW, supplied by the Balancing Services Entity e in real time, for the Imbalance Settlement Period t.
$m F R R Q_{e, a s, t}^{u p}$	the segment, as, of step, s, in MW of the upward mFRR Balancing Capacity Offer validated by the Balancing Services Entity, e, for the Dispatch Period which includes the Imbalance Settlement Period, t, based on the latest execution of the ISP, the resolution time horizon of which includes the specific Imbalance Settlement Period t.
$T_{e, t}^{m F R R, u p}$	the percentage of time within an Imbalance Settlement Period t when the Balancing Service Entity e was available for the provision of upward mFRR in real time.
$m F R R Q_{e, t}^{d n}$	the downward Balancing Capacity for mFRR in MW, supplied by the Balancing Services Entity, e, in real time, for the Imbalance Settlement Period t.

$T_{e, t}^{m F R R, d n}$	the percentage of time in an Imbalance Settlement Period t,during which the Balancing Services Entity e was available for the provision of downward mFRR in real-time.

The upward and downward Balancing Capacity for aFRR, in MW, supplied by a Balancing Service Entity e, for an Imbalance Settlement Period t, shall be calculated as follows:
$a F R R Q_{e, t}^{u p} = \sum_{s}^{} \sum_{a s}^{} (a F R R Q_{e, a s, t}^{u p}) \times T_{e, t}^{a F R R, u p}$
$a F R R Q_{e, t}^{d n} = \sum_{s}^{} \sum_{a s}^{} (a F R R Q_{e, a s, t}^{d n}) \times T_{e, t}^{a F R R, d n}$
