ENTSOG Tariff NC - Implementation Document 2nd Edition

Then, tariffs are calculated in the case of the postage stamp RPM and following the rules of the CWD counterfactual, according to Article 8. \\ For postage stamp , entry (resp. exit) tariffs are derived for each TSO by multiplying the allowed revenue by the entry (resp. exit) share of revenues, and dividing the result by total forecasted entry (resp. exit) bookings. Tariffs are identical for all points in entry and all points in exit: this is a result of postage stamp. This is shown in the table below.

TARIFFS €/(kWh/h)/a

\\ For CWD , given the 2 cost drivers, calculations are more complex. Compared to postage stamp, it is necessary to consider distances between points. In accord- ance with Article 8 on CWD counterfactual, distance is here supposed to be measured by the shortest pipeline distance, which is the actual distance along pipelines that is necessary to connect two points of the network. Tariffs derived with the CWD RPM are presented in the above table, but the steps to calculate them are developed below.
