ENTSOG Tariff NC - Implementation Document 2nd Edition

ARTICLE 29 INFORMATION FOR PUBLICATION BEFORE THE ANNUAL YEARLY CAPACITY AUCTIONS

Responsibility: publication by TSO/NRA, as NRA decides

Figure 34 below summarises the set of information for publication before the annu- al yearly capacity auctions. To ensure sufficient clarity regarding the derivation of binding reserve prices published before the auctions, this set also includes informa- tion on: (1) applied multipliers and justification for their level; (2) applied seasonal factors and justification for their application; and (3) an assessment of the probabil- ity of interruption. Therefore, although such publication of reserve prices and the associated informa- tion occurs before the annual yearly capacity auctions, it covers all standard capacity products. This set represents the full explanation of the rationale behind the published binding reserve prices. Such information needs to be published both at IPs and non-IPs where the CAM NC applies. For the first time when the information before the annual yearly capacity auctions is published in June 2018. Still, Article 27(5) foresees that the deadline for publishing the approved tariffs calculated in accordance with the new RPM is 31 May 2019. There is a discrepancy between the two rules of the TAR NC. Further to stakeholder feedback received, ENTSOG is of the opinion that the full set of information outlined in Article 29 must be published for the first time in June 2018 and then each follow- ing year onwards. ENTSOG notes that since NRAs will be consulting per Article 28 on multipliers, seasonal factors and interruptible discounts with the deadline of 31 May 2019, it may be possible that the binding publication of June 2018 does not cover NRA justification for the level of multipliers and for the application of seasonal factors. ENTSOG is of the opinion that the ongoing NRA consultation on multipliers, seasonal factors and interruptible discounts must not impact the reserve prices pub- lished in June 2018 and such reserve prices must therefore be binding for theentire gas year from October 2018 to September 2019. For an example on how to structure the assessment of the probability of interruption, please see Annex Q.
