ENTSOG Tariff NC - Implementation Document 2nd Edition

Given these inputs, the increase of the tariff has been calculated for different scenarios: 1. M = 1 for all non-yearly (quarterly, monthly, daily) standard capacity products; no seasonal factors 2. M = 1 for all non-yearly standard capacity products; with seasonal factors 3. M = 1.5 for all non-yearly standard capacity products; no seasonal factors 4. M = 1.5 for all non-yearly standard capacity products; with seasonal factors When seasonal factors have been used for the calculations, those have been calculated following the methodology described in the TAR NC, using a power of 1 for Article 15(3)(e). In the Table 63, the actual bookings as well as the partly applied seasonal factors can be found.

Table 63: Forecasted contracted capacity and seasonal factor in example

The calculation of tariffs T follows a very simple approach using the Annual average of adjusted forecasted contracted capacity (AAAFCC):

The adjustments of the Forecasted contracted capacities are necessary to exactly meet the revenue cap due to the multipliers. The AAAFCC is calculated as following:
