Article 8- The transportation company shall prepare the transportation schedules in accordance with the notifications to be filed as per Article 7 or, in the absence of such notifications, in accordance with the amounts to be determined in line with the principles and procedures set forth within the scope of the rules pertaining to network operation. Amounts stated in the notifications received after the relevant deadline shall be scheduled after those stated in the notification received in time, and subject to system availability. In scheduling, uninterrupted transportation service has priority.
After scheduling the transportation amounts, the transmission company shall send a notification of approval to the suppliers. Such notification shall be maintained by the parties.
In case of any change in the scheduled amounts, all parties affected by such change shall be informed of the change, simultaneously.
Determination of transported amounts
Article 9- At the end of a system day, the transmission company shall determine the transported amounts of natural gas at each entry and exit point. The transmission company shall inform of these amounts all parties enjoying the transportation service provided by the transmission company.
Interruption or Reduction of Delivery Amount, Dispatch and Balancing Service
Interruption or reduction of delivery amount
Article 10- The transmission company shall have the right to interrupt service or reduce delivery amounts at the entry and exit points;
- immediately, in cases where there is natural gas leakage in the transmission network, where the safety of the transmission network is under serious risk, or where the pressure or the quality of natural gas in the transmission network would present danger to people or goods if delivered;
- upon notifying parties within the periods set forth in the rules pertaining to network operation, in cases of system imbalance;
- as per the principles set forth in the transportation contracts, if required during maintenance, repair, control, connection or renewal works on the transmission network.
In such cases, suppliers shall act as per those instructions of the transmission company related to service interruptions or reduction of delivery amounts.
In cases of service interruptions or reductions in delivery amounts due to system imbalance;
- if it is understood within the same system day who the supplier causing the interruption or reduction in delivery amounts is, reduction shall be applied to natural gas deliveries, proportional to the imbalance caused by the supplier in question.
- If it cannot be understood within the same system day who the supplier causing the interruption or reduction in delivery amounts is, service to interruptible customers in the region affected by the system imbalance shall be interrupted first. Then, reduction in the delivery amounts shall be applied to non-interruptible transportation services, proportional to each customer’s respective capacity, in the order determined by the suppliers for their respective customers.
For the purposes of determining the suppliers whose supplies are insufficient, the transmission company shall request information and documents from the suppliers as to whether each has provided the scheduled amount of natural gas or not.
