ENTSOG Tariff NC - Implementation Document 2nd Edition

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.
