ENTSOG Tariff NC - Implementation Document 2nd Edition

The calculation of average distances for each entry point to the group of exit points is carried out by analogue processing. In contrast to exit points, for entry points there is a distinction regarding the average distance to intra-system exits and to cross-system exits. The distance to intra system exits is the actual distance to the exit point named ‘Consumption’, while the distance to the cross-system exits is again calculated with the formula above as the commodity weighted average between the cross-system exits. This distinction is made to later define the intra/cross system drivers for entry points.

Acc. to Art 5(5)(a)

Table 31: Cost drivers and entry commodity split

Drivers in this Scenario are referred to as the product of Flows and the average dis- tance. For exit points it is the respective flow at this point, times the average distance to the entry points in this given system which is calculated as in the previous section.

The Drivers for each entry point are calculated by analogue processing. Similar to capacity, drivers for commodity intra-use and cross-use are only considered for the CAA, not for tariff derivation  1) . The entry flow is also split and allocated to cross- or intra-system use. This split is made in accordance to Article 5(5)(a) and explained in the following paragraph.

 1) As for the Capacity section, a TSO does not publish cross-use entry commodity tariffs, cross-use exit commodity tariffs, intra-use entry commodity tariffs or intra-use exit commodity tariffs. A TSO only publishes entry commodity tariffs and exit commodity tariffs, regardless of the intra- or cross-use of the flow.
