ENTSOG Tariff NC - Implementation Document 2nd Edition

Annex A Articles 3(19) and 6(4)(b) – Example of Clustering and Equalisation

Entry-exit system with two entry points (IP) and three exit points to consumption (C). Objective: Equalisation applied to the consumption points.

As explained in Part 1 ‘Overview of the TAR NC requirements’, Chapter II ‘Reference price methodologies’, Section ‘Article 8(1)(c) – distance calculation’, the calculation of the shortest pipeline distance can be determined by: (1) selecting a focal point within the grid representing the cluster; or (2) calculating the weighted average distance of all physical points combined in the cluster. The tariff at VCP may be calculated by taking this cluster as one exit point following either of these two approaches. Applying the RPM will calculate one single exit tariff to each of all three consumption points.
