ENTSOG Tariff NC - Implementation Document 2nd Edition

CAA RELATING TO TRANSMISSION SERVICES REVENUE FROM CAPACITY-BASED TARIFFS This Part considers the CAA on capacity-based transmission tariffs. In this Part, one assumes that contracted capacity at exit IPs corresponds to ‘cross- system network use’ and contracted capacity at domestic consumption points cor- responds to ‘intra-system network use’. Further, Cost Drivers in this Scenario are a combination of distance and capacity . For the expected revenues, the allowed total capacity revenue and a split of this into exit and entry share is given.

Table 26: Average distance to a specific exit (or entry)

Taking into account the capacity and the distance of every entry of the system to one specific exit, a capacity weighted average distance can be calculated for this exit point. Capacities are shown in the following Table C. This average distance of one exit point is determined by the sum of each entry capacity, times the distance to this respective entry point from the considered exit point, divided by the sum of all entry capacities. An average distance for a specific exit point would be calculated as in the following equation.

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