ENTSOG Tariff NC - Implementation Document 2nd Edition

PART III SAME RPM APPLIED SEPARATELY BY THE TWO TSOs IN THE SAME ENTRY-EXIT SYSTEM

As an alternative to the default approach of joint application in a merged entry-exit system, TSOs may apply separately the same RPM. The maps used for the joint application in the same entry-exit system are also used here. 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. As a reminder, the removal of points A1 and B3 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.

Due to NRA decision/calculation. In example, ITC value is chosen by an NRA decision (ex ante).

Table 51: Input data after the merger (separate case)

In the above table, one assumes that the NRA in charge of the merged entry-exit system decides that an ITC of 10M€ will be set up from TSO B to TSO A to ensure the revenue reallocation. The NRA decides that TSO B will charge tariffs at its remaining points in one revenue pot but for 2 purposes: 1) collecting its own allowed revenue (the same as in Part I), and 2) collecting the ITC. Meanwhile, TSO A will charge tariffs at its remaining points for the sole purpose of collecting its own allowed revenue whose value is diminished by the predefined value of the ITC, in comparison to Part I. Therefore, TSO A will collect 60M€ (instead of 70M€ before the merger) and TSO B will collect 75M€ (instead of 65M€).
