In the event of systematic failure to attain a feasible Market Schedule, the HETS Operator shall impose a charge on the respective Participant for each Balancing Service Entity it represents, which shall be equal to $NCNAM{S}_{e,m}$ and shall be calculated as follows:

$NCNAM{S}_{e,m}=\left(1+A_{NAMS}\right)\times \sum _r\sum _{d\in m}\left(UNCNAM{S}_r\times V{Q}_{e,r,d}\right)$

where:
$UNCNAM{S}_r$ the unitary non-Compliance Charge for infeasible Market Schedule in €/MWh, which may vary depending on the cause of the infringement, r.
$A_{NAMS}$ a premium coefficient for the charge, which depends on the number of days within a month, when an infeasible Market Schedule is observed.
$V{Q}_{e,r,d}$ the quantity corresponding to the said infringement by the Balancing Service Entity, e, in MWh, the reason for the infringement, r, and the Dispatch Day d of the month m.

When calculating the quantity of the infringement, $V{Q}_{e,r,d}$, tolerance margins may be applied, $TO{L}_{r,e}$, which may vary depending on the cause of the infringement and the Balancing Service Entity category.

The numerical values of the unitary charges $UNCNAM{S}_r$, the charge increase adjustment factor $A_{NAMS}$ and the tolerance margins, $TO{L}_{r,e}$, shall be determined by decision of the RAEWW, subject to a recommendation from the HETS Operator. This decision shall be published at least two months prior to the implementation of the new values of the above parameters.

Details regarding the calculation of the infringement quantity $V{Q}_{e,r,d}$ for each Dispatch Day d are described in the “Infeasible Market Schedule Calculation Methodology”.
