Fee note
The fees above are for the 2026/2027 storage year. The system service fee is not applicable if the storage customer already has a storage contract in place for the same facility during the term of this contract. For the injection of a gas amount equivalent to the maximum (firm and interruptible) working gas capacity contracted under this storage contract, a reduced fee for variable costs of 0.00 € per injected MWh shall apply (i.e. for each storage bundle of the Etzel ESE Indexed Fast Churn product contracted under this storage contract, the Storage Customer may inject an amount of 250 GWh of gas taking advantage of the reduced fee for variable costs). For all injections exceeding an overall amount equivalent to the maximum (firm and interruptible) working gas capacity contracted under this storage contract, the regular fee for variable costs according to the Price Sheet (Annex IV of the GTCS) shall apply.
