5.4 IP Subscription and Use

5.4.1 CAPACITY SUBSCRIPTION AT NORTH-SOUTH LINK (FRANCE) Since April 2014, firm capacity has been set to 270GWh/d, to which up to 150GWh/d of interruptible capacity can be booked. GRTgaz also offers additional service to maximise the access to TRS with the JTS (Joint Transport Storage service) and mar- ket coupling mechanism. Annual capacities are sold through auctions once a year, annual interruptible capacity is available only if 95% of firm capacities has been sold. Since the North South link will disappear in November 2018, last auction for annual available capacity will occur in March 2018. Use of the North-South link is still very high, with a 95% use of available technical capacity in 2016. Firm capacity in the opposite direction is booked at 26%.
