MAR­GIT de­ter­mi­na­tions pur­suant to Ar­ti­cle 28 TAR NC

Commission Regulation (EU) 2017/460 of 16 March 2017 establishes a network code on harmonised transmission tariff structures for gas, known as the TAR NC. In accordance with the network code, the ruling chamber determines mark-ups or discounts on the reserve price for standard capacity products (REGENT) on a yearly basis. The German transmission system operators (TSOs) are the addressees of the determination. The rules apply to every bookable interconnection point (cross-border interconnection point) in the German transmission system. Corresponding rules for other booking points are set out in the determination BEATE 2.0.

Discounts at entry points from LNG facilities and booking points from infrastructure developed to end isolation in the energy sector (Article 9(2) TAR NC)
A discount may be applied to these capacity-based transmission tariffs for the purpose of increasing security of supply. Diversifying sources of natural gas reduces dependence on individual producing countries, increasing security of supply. Granting discounts may encourage this kind of diversification.

Mark-ups for non-yearly standard capacity products (Article 13 TAR NC)
Mark-ups (multipliers) may be determined on the reserve price for quarterly, monthly, daily and within-day standard capacity products. The option of non-yearly booking allows network users to make structured bookings; that is, they can book different amounts of capacity in the course of the year. This type of booking behaviour tends to lead to vacancy costs. The aim is for these to be absorbed cost-reflectively by the multipliers on the reserve price.

Determination of seasonal factors (Article 15 TAR NC)
Different seasonal factors may be applied to individual months with the aim of stabilising network usage (bookings) over the calendar year and keeping vacancy costs down.

Discounts for interruptible standard capacity products (Article 16 TAR NC)
TSOs are required to offer interruptible standard capacity products as well as firm standard capacity products with guaranteed transport. The discount should adequately reflect the risk of interruption in the former.
