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

.
\\
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.
