The simplified tariff model presented in this second example is designed for a system
in which the capacity weighted distance RPM is used. It is supposed to enable net-
work users to forecast future tariffs for different capacity products by creating their
own capacity forecast. The example below is only a screen shot of the actual model,
the link to the Excel file is:

On the ‘Distance Matrix’ sheet below and in the Excel file the weighted average
distance and the weighted average cost for each entry point or each cluster of entry
points and for each exit point or each cluster of exit points is calculated as per TAR
NC Article 8(2)(a) and (b). On this sheet, ‘x’ means that a given entry and a given
exit point cannot be combined in a relevant flow scenario.
On the ‘Tariff Calculation’ sheet below and in the Excel file the part of the transmis-
sion services revenue to be recovered from capacity-based transmission tariffs from
all, and at each, entry and exit points is calculated applying the entry-exit split, as
per TAR NC Article 8(2)(d) and (e).
The parameters used for the multipliers, storage discount, entry/exit split and TSO
revenue to be recovered by capacity charges are set below and in the ‘Parameters’
sheet in the Excel file, as per TAR NC Article 8(2)(c).
The last screen shot below and the ‘Main sheet’ in the Excel file allows the user to
set out the forecasted contracted capacity bookings for firm and interruptible
products and to show indicative reserve prices.
