ENTSOG Tariff NC - Implementation Document 2nd Edition

TAR NC Implementation Document – Second Edition September 2017 |

The second part ‘Simulation’ contains the simulation of all the costs for flowing

1 GWh/day/year for each IP per product type and tariff period. In order to

improve transparency it was decided to calculate the simulation costs not only

for yearly products, but also for quarterly, monthly and daily products. ENTSOG’s

solution also allows to provide information for within-day products as an option.

The calculation of the simulation costs includes the capacity charges, flow-

based charges and all kind of charges which are applied at the respective IP –

e. g. metering charges, gas quality conversion charges, biogas charges. Those

elements, which are part of the calculation will be added in the remark for the

respective filed of the simulation cost value. The calculation of the simulation

cost values is made under the assumption that the load factor is 1, meaning

that the gas flow is constant over the year – 1GWh every day of the year.

Additionally, the standardised table is designed to have the following features:

The TAR NC requires that only IPs are covered in the standardised table.

However, ENTSOG’s solution allows publishing the required tariff information

for non-IPs as well.

Since the TAR NC requires to specify in the standardised table ‘whether the

capacity is firm or interruptible’ and since the firm capacity products with

‘conditions’

fall into the category of firm capacity, the standardised table must

also include the required tariff information for firm capacity products with

‘conditions’. It is ENTSOG’s recommendation for TSOs/NRAs to specify in the

‘remark’ field of the standardised table which firm capacity product with

‘conditions’ it is.

If the local currency is other than the euro, the ENTSOG’s TP uses the exchange

rates of the ECB for recalculating the tariff and simulation values from local

currencies to Euro, where applicable. The recalculation is carried out

automatically by the ENTSOG’s TP on a daily basis, following the updates of the

exchange rates published by ECB.

In some cases, it is not possible to specify the full set of information for certain

product types. For example, no tariffs for firm capacity products will be

published at IPs where only non-physical backhaul capacity is offered. Another

example could be, that a MS does not apply commodity charges at all. In such

cases, this will be shown as an ‘NA’ in this field of the standardised table, which

stands for ‘Not applicable’ and is supplemented by an explanation for the

reason of that.

For the information to be published in the standardised table on ENTSOG’s TP, a

separate disclaimer states out, that in case of discrepancies between the informa-

tion published on the ENTSOG’s TP and the information published on the website

of a TSO/NRA

, the information published on such TSO/NRA website shall prevail

in accordance with Article 31(4) of the TAR NC.

products with ‘conditions’.
