ENTSOG Tariff NC - Implementation Document 2nd Edition

INTERACTION WITH OTHER NETWORK CODES AND GUIDELINES

As indicated above, Article 8(6) of the Gas Regulation identifies possible areas for the development of NCs, most of which are now covered by existing NCs. The TAR NC covers ‘ rules regarding harmonised transmission tariff structures’ in point (k). All NCs constitute and form integral parts of the Gas Regulation; its consistent and coherent implementation requires due consideration of the interactions between the Gas Regulation and any given NC, and between NCs. The TAR NC interacts with other NCs and Guidelines   1) as follows: \\ Amended CAM NC: certain rules of the TAR NC refer specifically to interconnection points (‘IP’) , subject to the Amended CAM NC. The listed rules in the TAR NC address tariff-related issues of the Amended CAM NC: Chapter III ‘Reserve prices’, Chapter V ‘Pricing of bundled capacity and capacity at virtual interconnection points (‘VIP’) ’, Chapter VI ‘Clearing and payable price’, Article 28 on discounts, multipliers and seasonal factors from Chapter VII ‘Consultation requirements’, Article 31(2)–(3) on publication of certain tariff information on ENTSOG’s Transparency Platform (‘TP’) from Chapter VIII ‘Publication requirements’ and Chapter IX ‘Incremental capacity’. The Amend- ed CAM NC governs the process for offering incremental capacity, while the TAR NC sets out the tariff principles for incremental capacity. \\ Transparency Guidelines: Chapter VIII ‘Publication requirements’ sets out tariff transparency obligations that further elaborate and harmonise the tariff trans- parency obligations in the Transparency Guidelines. \\ BAL NC: the TAR NC treats the balancing activity of a TSO as a ‘third’ service category independent of transmission and non-transmission services. Balancing costs receive separate treatment given the application of a neutrality mechanism under the BAL NC. \\ INT NC: the TAR NC incorporates all the definitions introduced by the INT NC. \\ Chapter 2.2 of Annex I to the Gas Regulation (‘CMP Guidelines’) : although the Gas Regulation defines physical and contractual congestion, there is an indirect link between the TAR NC and the CMP Guidelines. The CMP Guidelines stipulate the detailed measures for solving contractual congestion, which can affect the TSO’s revenue recovery, as when implementing an oversubscription and buy-back procedure. As for definitions, the TAR NC incorporates those employed in Directive 2009/73/EC (‘Gas Directive’)  2) , the Gas Regulation, and other NCs: the Amended CAM NC, the BAL NC and the INT NC. For ease of reference, ENTSOG has published a compre- hensive list of all such definitions  3) .
