ENTSOG Tariff NC - Implementation Document 2nd Edition

Adjustments at Certain Points

ARTICLE 9 Discounts at entry-points-from/exit-points-to storage facilities and infrastructure ending the isolation, and at entry-points-from LNG facilities

Responsibility: subject to consultation per Article 26(1) by TSO/NRA, as NRA decides; subject to decision by NRA

General Figure 19 illustrates the TAR NC requirements regarding the discounts at three cat- egories of points on the system: (1) entry-points-from/exit-points-to storage facilities; (2) entry-points-from LNG facilities; and (3) entry-points-from/exit-points-to infra- structure ending isolation of MSs in respect of their gas transmission system. These discounts are in effect adjustments to the results of the RPM, but separate from the benchmarking, rescaling and equalisation identified in Article 6. ENTSOG has received the feedback through ACER that in this aspect, the difference between the term ‘reference price’ and the term ‘transmission tariff’ should be clarified. ENTSOG highlights that benchmarking, rescaling and equalisation foreseen by Arti- cle 6(4)(a)-(c) are adjustments to reference prices, whereas adjustments foreseen by Article 9 are adjustments to capacity-based transmission tariffs. ENTSOG also notes that in case of the firm yearly product, the terms ‘reference price’ and ‘capacity-based transmission tariff’ coincide.
