The charge for the Imbalance Component is calculated by the HETS Operator for Balance Responsible Entities and Balancing Service Providers for each month m of the year, as follows:

$BM{F}_{p,m}^{IMB}=UNBM{F}^{IMB}\times \left\{EA{E}_{p,m}^{up/dn}+\sum _{t\in m}^{ }\sum _{c\in p}^{ }\left|FIM{B}_{p,c,t}\right|\right\}$

Where,

$BM{F}_{p,m}^{IMB}$ The Balancing Market Fee Imbalance Component for Participant p and month m.

$UNBM{F}^{IMB}$ The Unit Charge corresponding to the Imbalance Component of the Balancing Market Fee, which is calculated in accordance with the provisions of Article 6.2.

$EA{E}_{p,m}^{up/dn}$ The sum of the total upward and downward activated energy in MWh per Balancing Service Provider p for month m.

$FIM{B}_{p,c,t}$ The amount of Final Imbalance in MWh per Balance Responsible Party p, for each Entity category c, and for each Imbalance Settlement Period t, as the algebraic sum of the Final Imbalances in MWh for each entity belonging to the Entity category, c

c The categories of entities specified in Article 6.2 paragraph 1.

In the above calculation, both upward and downward activated energy are considered to have a positive sign. Activated energy means the activated Balancing Energy for mFRR and aFRR as well as activated energy for non-balancing purposes.

The charge for the Energy Component is calculated by the HETS Operator for Participants for each month m of the year, as follows:

$BM{F}_{p,m}^{EN}=UNBM{F}^{EN}\times \left(M{Q}_{p,m}+RealSc{h}_{p,m}\right)$

Where:

$BM{F}_{p,m}^{EN}$ The Balancing Market Fee Energy Component for Participant p and month m.

$UNBM{F}^{EN}$ The Unitary Charge corresponding to the Energy Component of the Balancing Market Fee, which is calculated in accordance with the provisions of Article 6.2.

$M{Q}_{p,m}$ The sum of the energy absorbed (calculated at the Transmission System-Distribution System Boundary) and the energy produced per Participant p for month m. In the above calculation, both the energy absorbed and the energy produced are considered to have a positive sign.

$RealSc{h}_{p,m}$ The Trading Schedules for Imports/Exports of Electricity per Participant p for the month m. Import/export schedules of the HETS Operator and the Transmission System Operator are excluded. In the above calculation, both imports and exports are considered to have a positive sign.
