Basis of calculation for the glassworks surcharge (GHZ):
Fixed reference value (index base value) for gas: €80.00/MWh
The monthly EGIX® (European Gas Index) value can be found at the following link
Seven working days before the start of the new month, the integer value of the monthly EGIX® (THE) is used. Select the item “THE” in the “Monthly European Gas Index” overview to see this value.
Explanation of the calculation
Formula:
Difference between EGIX® and base value x calculation factor = €/tonne
Sample calculation:
EGIX® value = €156.00/MWh:€156.00 – €80.00 (base value) = €76.00 x €2.65 MWh/tonne (calculation factor) = €201.40/tonne
= €0.20 /kg+ yield/cut surcharge (calculation factor: 0.8)
Total surcharge from GHZ:
€0.20 /kg ÷ 0.8 = €0.25 /kg
Please note that it is always rounded to the nearest cent.
