General Concepts
ARTICLE 1
SUBJECT MATTER
Responsibility: no implications for TSO/NRA responsibility
As indicated by its title, the TAR NC covers ‘
harmonised transmission tariff structures
for gas
’, one of the areas for developing a NC as stated in Article 8(6)(k) of the Gas
Regulation. The ‘tariff structures’ cover the ways TSOs collect revenues associated
with the provision of services at entry and exit points, via capacity- and
commodity-based transmission tariffs and non-transmission tariffs. For capacity-
based tariffs, the ‘tariff structures’ cover the methodologies both for calculating the
reference price and for deriving specific tariffs based on the reference price.
Article 1 also provides some examples of TAR NC rules: RPM application, consulta-
tion requirements, publication requirements and the calculation of reserve prices.
The list is not exhaustive.
ARTICLE 2
SCOPE
Responsibility: the NRA may decide to apply the CAM NC at entry-points-from/
exit-points-to third countries, in which case the ‘limited’ scope rules of the
TAR NC apply automatically. The ‘limited’ scope rules may be extended per
national decision to: (1) entry-points-from/exit-points-to third countries where the
CAM NC does not apply; and (2) non-IPs other than entry-points-from/exit-points-
to third countries
As a general remark, ENTSOG notes that the TAR IDoc is written to reflect the refer-
ence of IPs and non-IPs as set out in the TAR NC. However, nothing prevents the
relevant national authority to extend the ‘
limited scope
’ rules to non-IPs. Such
possibility is recognised explicitly in the TAR NC text for entry-points-from/exit-
points-to third countries. It is ENTSOG’s assumption that such possibility is also valid
for other non-IPs: based on the principle that the EU-wide NC only sets the minimum
degree of harmonisation and the relevant national authority can further detail the EU
law respecting its supremacy. Therefore, the TAR IDoc should be read together with
Figure 3.
