TAR NC Implementation Document – Second Edition September 2017

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.

information on the possibility to expand the standardised table to include non-IPs.
