WEIGHT OF COST FOR ENTRY POINTS

The formula is as follows.

Average entry distances calculated at the previous step are used, as well as the original table for forecasted contracted capacities at entry points (not the table with corrected capacities, because now there is no reference to exit points and the feasibility of flow scenarios). In the Main Table , the value of the denominator is named ‘Sum prod’ and is 6,491.82. For example, the weight of cost for entry point A is calculated below, according to Main Table values.

It means that entry point A has to collect 0.8% of entry revenues. Similar calcula- tions apply for other entry points. Results for all entry points are in the Main Table . The heaviest shares of entry costs have to be borne by entry IPs ‘B’, ‘K’, and ‘M’ with respective shares of 20.0%, 21.3% and 24.9%. The lightest share of entry costs has to be borne by storage point C with a share of 0.5%. The sum of weights over all entry points is of course 100%.

WEIGHT OF COST FOR EXIT POINTS

The formula is as follows.

Average exit distances calculated at the previous step are used, as well as the original table for forecasted contracted capacities at exit points (not the table with corrected capacities, because now there is no reference to entry points and to the feasibility of flow scenarios). In the Main Table  1) , the value of the denominator is named ‘Sum prod’ and is 8,460.85. For example, the weight of cost for exit point A is calculated below, according to the Main Table values.

It means that exit point A has to collect 0.2% of exit revenues. Similar calculations apply for other exit points. Results for all exit points are in the Main Table . The heaviest shares of exit costs have to be borne by exit IPs ‘B’ and ‘M’ with respec- tive shares of 27.6% and 21.3%. The lightest share of exit costs has to be borne by storage point C with a share of 0.1%. The sum of weights over all exit points is of course 100%. The next stage is to derive tariffs at entry and exit points (as per Article 8(2)(c) to (e)), prior to the adjustment for storage discounts (Article 9(1)).

 1) To help with calculations, a row transposing the column of forecasted contracted exit bookings has been added in the table (‘Transpose’ row).
