When to perform cost allocation assessments
In terms of process, Article 5(1) specifies an obligation for the NRA or TSO, depend-
ing on the entity conducting the consultation, to ‘
perform the […] assessments and
shall publish them as part of the final consultation referred to in Article 26
’. Article
5 sets out no such obligation at an earlier stage, so it is only optional to perform such
assessments at a separate stage prior to the final consultation. In accordance with
Article 27(5), the first obligation which is set out in the TAR NC in terms of timeline
for the cost allocation assessments is that they must be performed, decided upon
and published no later than 31 May 2019. The second obligation provided by the
same Article 27(5) is that such process must be accomplished in a periodic way, at
least every five years starting from the 31 May 2019.
ENTSOG has received feedback through ACER that the initial justification for
exceeding 10% threshold should be provided, where available, at the stage of TSO/
NRA consultation. ENTSOG concluded that the TAR NC foresees an obligation to
provide such a justification as part of the final NRA decision after the consultation
process. Although Article 5 sets out no such obligation at an earlier stage, ENTSOG
recognises that, where available, the initial justification for exceeding 10% threshold
may be provided at the stage of TSO/NRA consultation.
