Multi-TSO Entry-Exit Systems
MULTI-TSO ARRANGEMENTS
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) ‘ITC’ stands for inter-TSO compensation.
