Hour-ahead Capacity
The Operator offers to transport volumes of gas in excess of the booked firm capacities, during any single Hour of a day – an Hour-ahead capacity product. Shippers may request such product by submitting nominations with at least two (2) full hours' lead time.

Such request is subject to the Operator's approval, which will be considered approx. 1½ hour before the Hour in question.

Such approval will, however, be subject to availability of the technical capacities and subject to the Shipper having delivered sufficient volumes of gas at the Delivery Point. Once approved, the transportation will be guaranteed by the Operator and the Shipper will be informed of the result hereof by means of an Approved Nomination message.

The Shipper will only pay a tariff for approved Hour-ahead capacity (and not for the nominated (requested) Hour-ahead capacity) yielding a 100% utilization of the Hour-ahead capacity product.
