ENTSOG Tariff NC - Implementation Document 2nd Edition

For non-IPs, one should distinguish between the two categories: (1) non-IPs that are entry-points-from/exit-points-to third countries; and (2) other non-IPs, such as domestic exit points, entry-points-from/exit-points-to storage facilities. Such a distinction is necessary when analysing which TAR NC rules that are by default lim- ited to IPs can be extended to non-IPs: \\ If the NRA has decided to apply the CAM NC at entry-points-from/exit-points- to third countries, then Chapters III, V, VI, IX and Article 28 of the TAR NC apply without the need for an additional decision. This however does not explicitly include Article 31(2)-(3) dealing with publication of information on ENTSOG’s TP in the standardised table  1) . \\ The TAR NC is silent as to the expansion of application of Chapters III, V, VI, IX and Articles 28, 31(2)-(3) to other non-IPs. It is ENTSOG’s assumption that the TAR NC leaves this possibility at the national discretion. The TAR NC incorporates the definitions set out in the Gas Regulation, the Gas Directive and from the other network codes. The definitions of transmission services and non-transmission services guide the attribution of TSO revenues. The TSO recovers transmission services revenue from the sale of capacity and from commodity charges, and recovers non-transmission services revenue via separate non-transmission tariffs. Transmission tariffs are capacity-based by default, with two exceptions limited to two types of commodity- based transmission tariffs. The distinction between transmission services and non-transmission services affects some TAR NC rules. The list above identified Chapters and Articles limited in scope to IPs; they only refer to transmission services. The rest of the TAR NC is mostly about transmission services but also captures some rules for non-transmission services. CAA aim to identify the degree of cross-subsidisation between intra-system (in other words, domestic) and cross-system use (in other words, cross-border with reference to entry-exit systems rather than MSs). They outline the methodology for determin- ing the ratio between the revenues recovered from cross-system users and intra-system users.

 1) Please refer to Chapter VIII ‘Publication requirements’, Article 31(3)(c) – standardised table on ENTSOG’s TP for further information on the possibility to expand the standardised table to include non-IPs.
