ENTSOG Tariff NC - Implementation Document 2nd Edition

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.
