ENTSOG Tariff NC - Implementation Document 2nd Edition

Multi-TSO Entry-Exit Systems

MULTI-TSO ARRANGEMENTS

ARTICLES 10 AND 11

Responsibility: subject to consultation per Article 26(1) by TSO/NRA, as NRA decides; subject to decision by NRA

General Article 10 addresses multi-TSO arrangements in entry-exit systems within one MS. Current examples are Austria, France, Germany, Hungary, Italy and Spain. Article 11 addresses multi-TSO arrangements in an entry-exit system covering more than one MS, like the current system that extends across Belgium and Luxembourg. Application of same/different reference price methodology jointly/separately by TSOs involved Subject to exceptions, Article 6(3) of the TAR NC requires the application of the same RPM to all entry and exit points in a given entry-exit system. This general rule applies within a MS regardless of the presence of multiple TSOs in a given entry-exit system. The exceptions are in Article 10 for multi-TSO entry-exit systems within a MS, and in Article 11 for multi-TSO entry-exit systems covering more than one MS. The exception rules distinguish along two dimensions: (1) whether the RPMs are the ‘same’ or ‘different’ types; and (2) ‘joint’ and ‘separate’ RPM application. Figure 20 shows different options under Articles 10 and 11.  1)
