Annex E
Article 8 – Example of Capacity
Weighted Distance Counterfactual
This example intends to illustrate the schematic approach described in Annex D. It
depicts a fictional network but follows the approach set out in Article 8 for the CWD
counterfactual comparison.
Its goal is to derive capacity tariffs based on CWD
at
entry and exit points.
This is a one-TSO entry-exit system (or ‘entry-exit zone’ EEZ 1) with the following
points.

Table 33:
List of network points
The TSO network is made of 20 points (A to T), some of which being both entry and
exit points:
\\
13 entry points
(including 2 storage points only connected to this TSO, 6 IPs
allowing entry, 3 internal production points, and 2 LNG regasification points)
\\
11 exit points
(including 2 storage points only connected to this TSO, 5 IPs
allowing exit, and 4 consumption points)
\\
2 other points
(S and T) at pipeline junctions, used only for distance calcula-
tions.
The map of the network is depicted on the next page.
