Table 29:

Distances between entries and exits

The first Table shows the distance from each exit point to each entry point of the sys-

tem. This is exactly the same matrix as for the previous capacity example for CAA

Table 30:

Average distance to a specific exit (or entry)

Taking into account the flows and the distance of every entry of the system to one

specific exit, a commodity weighted average distance can be calculated for this exit.

Flows are shown in the following Table C. This average distance of one exit is deter-

mined by the sum of each entry flow, times the distance to this respective entry from

the considered exit, divided by the sum of all entry flows. An average distance for a

specific exit would be calculated as in the following equation.

 1) Consumption refers to ‘intra-system network use’, as per the comment at the start of Part II. It corresponds to the

amount of gas flows, as per Article 5 provisions. One assumes here that this amount of gas flows is the forecast used for

the RPM application (another assumption could have been to use past actual values).

 2) For this commodity-based CAA, similarly to the capacity-based case, only entry and exit points connected via a flow

scenario are considered here. The flow scenario assumption is not mandatory in Article 5 though.
