TAR NC Implementation Document – Second Edition September 2017
STANDARDISED TABLE ON ENTSOG’S
TRANSPARENCY PLATFORM
Responsibility: TSO/NRA sends information to ENTSOG’s TP, as NRA decides
The TAR NC requires the publication of information directly on ENTSOG’s TP in a
standardised table. As outlined in Annex T, publication will occur at least twice per
calendar year (before the tariff period and before the capacity auctions, except for
the Portuguese case where both of such deadlines coincide due to the start of the
tariff period in July) for each member state where the tariff period is equal to one
year, except for the tariff period July-June, since in this case the publication of infor-
mation before the tariff period and before the annual yearly capacity auction will oc-
cur simultaneously. It is also possible to update the publication more often than
twice per calendar year due to technical, regulatory or national reasons. As Table 15
shows, the standardised table must report the following information: reserve prices
for standard capacity products, flow-based charges and a simulation of all the costs
for flowing 1GWh/day/year for each IP.
The TAR NC lists the minimum requirements for designing the standardised table.
In general, the standardised table must include: the IP name, the gas flow direction
and the relevant TSOs’ names. For reserve prices, the additional information in-
cludes: whether the relevant product is firm or interruptible, whether its duration is
yearly, quarterly, monthly, daily or within-day, the applicable tariff per kWh/h and
per kWh/d in both local currency and the euro. The table must also indicate flow-
based charges and simulation of all the costs for flowing 1GWh/day/year for each IP
in local currency and the euro.
The TAR NC contains appropriate caveats due to different capacity units and
different currencies applied in the EU. The following information included in the
standardised table is non-binding: (1) the applicable tariff per kWh/d (or per kWh/h)
if the applied capacity unit is kWh/h (or kWh/d); and (2) the applicable tariff in euro
and the simulation of all the costs in euro if the local currency is other than the euro.
ENTSOG’s TP has been adjusted so that all the information could be submitted from
the TSO/NRA to ENTSOG’s TP in a consistent way, to ensure a user-friendly
visualisation in a comparable and easy accessible way for the stakeholders. The set
of tariff information required by the TAR NC to be published on ENTSOG’s TP has
been divided in two parts where each part includes the minimum requirements
mentioned above
1)
.
\\
The first part ‘Tariff data’ shows the reserve prices for all products and the flow-
based charges at a given IP. Although the TAR NC requests the start and end
date of the respective products, another approach was chosen for the
implementation. A validity period: (1) is given for each product type
2)
; (2) is
defined as the longest duration of a given product type where the tariff for such
product type is the same; and (3) must be no longer than a tariff period
3)
. This
approach reduces the number of rows in the standardised table significantly, as
the product start- and end date is implicitly indicated by showing the product
type. For example, for the validity approach only one line is displayed in the
standardised table in the case of the same prices for daily products, instead of
365 lines.
1) See Annex Y for demonstration of the standardised table on ENTSOG’s TP.
2) By ‘product type’ ENTSOG understands the following different product types: yearly as one type, quarterly as another
type, and so on for monthly, daily and within-day.
3) Where the tariff period does not coincide with the gas year, there are two validity periods for a yearly product as the
yearly product spans over two tariff periods.
