Procedure in the event of an interruption of interruptible capacity

The service of providing contracted interruptible capacity at particular entry and/or exit point is interrupted in case the total nomination of daily volumes, of all transmission system users at the particular entry and/or exit point is larger than technical capacity.

Interruption of nomination is based on “pro-rate” principle.

A nomination of each user is accepted based on the firm capacity booking, however the remaining amount of nomination for an individual transmission system user is calculated from the difference between the technical capacity and the total nominated amount of all transmission system users, based on “pro rate“principle.

The transmission system operator informs a leader of a balance group in which the suspension occurred, about the location of the interruption (entry and/or exit point), reasons for interruption, beginning of interruption and duration of interruption.

Subject to the received nominations the transmission system operator provides information on the interruption one day before the gas day or during the gas day that the nomination refers to. In the event of an interruption of interruptible capacity a renomination shall be provided for the balance groups that the interruption refers to.
