TAR NC Implementation Document – Second Edition September 2017
PART II SAME RPM APPLIED JOINTLY BY THE TWO
TSOs IN THE SAME ENTRY-EXIT SYSTEM
If there is a merger of the 2 entry-exit systems, the joint application of the RPM by
TSOs is the default approach, as per Article 10(1) of TAR NC.
After the merger into one entry-exit system, the former IPs that connected the
previous entry-exit systems disappear, involving the need for revenue reallocation for
each TSO. In the example here, points A1 (for TSO A) and B3 (for TSO B) disappear,
and it is therefore necessary to recover the revenues formerly collected there at
remaining points. The figure below presents the newly merged entry-exit system.
The following table represents the remaining points and their technical and
forecasted booking capacities, in parallel with the same allowed revenue to recover
for each TSO. It is interesting to note that the removal of points A1 and B3 due to
the merger has changed the entry-exit split based on the forecasted bookings for
both TSOs: it is now 15/85 for TSO A and 80/20 for TSO B.
