ENTSOG Tariff NC - Implementation Document 2nd Edition

Annex G Article 10(3) – Example of Inter-TSO Compensation Mechanism Application in Multi-TSO Entry–Exit Systems within a Member State Policy choices for ITC derivation are not the topic of the example as the ITC mech- anism is subject to NRA decision. Article 10(3) of the TAR NC only gives general principles for the ITC establishment, and no specific requirements to follow. This Annex describes the case of an entry-exit system with two TSOs applying jointly/separately the same RPM. Two examples of RPMs will be considered: postage stamp and CWD. Before considering the multi-TSO case, it is useful to take the benchmark situation where each TSO has a specific entry-exit system. In a second step, the two entry-exit systems are merged.

Before the merger: \\ Part I presents the situation where the two TSOs apply separately the same RPM in their own entry-exit system.

After the merger: \\ Part II considers the case where the two TSOs apply jointly the same RPM after the merging of the two previous entry-exit systems into one. \\ Part III shows the case where the two TSOs apply separately the same RPM after the merging into one entry-exit system.
