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.
