Rejection of nominations and re-nominations or amendment of the requested gas quantity at interconnection points
Article 17
1. The transmission system operator may reject: (a) a nomination or re-nomination no later than two hours after the nomination deadline or the beginning of the re-nomination cycle in the following cases: (i) it does not comply with the requirements as to its content; (ii) it is submitted by an entity other than a network user; (iii) the acceptance of the daily nomination or re-nomination would result in a negative implied nomination flow rate; (iv) it exceeds the network user’s allocated capacity; (b) a re-nomination no later than two hours after the beginning of the re-nomination cycle in the following additional cases: (i) it exceeds the network user’s allocated capacity for the remaining hours, unless this re-nomination is submitted in order to request interruptible capacity, where offered by the transmission system operator; (ii) the acceptance of the hourly re-nomination would result in an expected gas flow change before the end of the re-nomination cycle. 2. The transmission system operator shall not reject a network user’s nomination and re-nomination on the sole ground that this network user’s intended inputs are not equal to its intended off-takes. 3. In case a re-nomination is rejected, the transmission system operator shall use the network user’s last confirmed quantity, if any. 4. Without prejudice to the specific terms and conditions applicable to interruptible capacity and capacity subject to congestion management rules, the transmission system operator may in principle only amend the gas quantity requested under a nomination and re-nomination in exceptional events, and emergency situations when there is an evident danger to system security and stability. Transmission system operators shall notify to the national regulatory authority any such action taken.
