3 Congestions 2 types of congestion can be met on existing GRTgaz network : Congestion Nord (North) : appears when high supply in the North leads to saturate transit within the North zone of GRTgaz network towards the South zone Congestion Sud-Est (South-East) : appears when weak output from the Fos-sur-Mer LNG terminals, low withdrawal from the South-East PITS, and high deliveries towards TIGF via the Cruzy interconnection point all happen For more information about the congestions that can be reached on GRTgaz network, please refer to the Winter- Outlook : 3

4 General process of congestion management Hierarchy of measures This winter (1/11 to 31/3), GRTgaz has several measures to cope with potential congestion on its network GRTgaz prioritizes market-based measures in its process of congestion management Congestion Info-Vigilance Take in account inter- TSO levers Locational Spread Locational Contract Call for Tender Powernext Plateform Object of this document Storage GRTgaz Manosque Security Stock AIO Article 14 of the Transmission Contract PUG Triggered by the government 4

5 Locational Spread Concept A double «within-day» locational product : Buying located downstream of the congestion Selling located upstream of the congestion Shipper B Shipper A A transitional stage before the merger : For winter 17/18, same operational process than current Locational for balancing : - Same process of Call for Tenders ( ) - Same product (daily volume ; Within-Day) - Same renomination controls (and possible penalty) Including TIGF points to handle South-East congestion The use of Locational Products for Balancing needs subsists and both use the same process and same plateform 5
