Coordination of works with an impact on the North – South link simultaneously with works impacting North entry points and Midi point. For the North – South link To increase the minimal capacity (CMNTt) we consider : On North: potential competition between Oltingue vs N>S link On South: potential competition between Fos vs N>S link Distribution rule of restriction capacities Distribution of restrictions for each contractual points regarding to the subscribed capacities prorata. 7 Shippers meeting – 28.01.2014 Main works for 2014 : Main pipes inspection Instrumented pigging (+ a period of repairs) on one pipe used to take away gas from Dunkerque & Taisnières H Instrumented pigging (+ a period of repairs) on one pipe used to take away gas from Taisnières H & Obergailbach Instrumented pigging (+ a period of repairs) on one pipe used to transit from North zone to South zone 8 Shippers meeting – 28.01.2014 Main works for 2014 : Main repairs A period of repairs on one pipe used to take away gas from Dunkerque, Taisnières H & Obergailbach A period of repairs on one pipe used to transit from North zone to South zone A period of repairs on one pipe used to evacuate gas from Fos terminal or to supply South zone 9 Shippers meeting – 28.01.2014 Main works for 2014 : Development Upgrading Taisnières H counting system Upgrading the Cuvilly interconnection Installation of a new counting system for more contractual reliability 10 Shippers meeting – 28.01.2014 Focus on week 27 (June 30th – July 6th) Dunkerque (225 GWh/j) Taisnières H (230 GWh/j) Obergailbach (500 GWh/j) Oltingue (0 GWh/j) Fos Shippers meeting – 28.01.2014 Focus on week 39 (September 22th – September 28th) Dunkerque (70 GWh/j) Taisnières H (605 GWh/j) Obergailbach (500 GWh/j) Oltingue (223 GWh/j) Fos 12 Shippers meeting – 28.01.2014 Comparison of 2013 vs 2014 maintenance program 13 Shippers meeting – 28.01.2014 Comparison summer period 2013 vs 2014 Transport capacities for Terminal points Available Capacities during Summer (TWh) 14 Tendency 2013 2014 Montoir 77 76 -2% Fos 69 76 +10% Total 146 152 +4% Shippers meeting – 28.01.2014 Comparison summer period 2013 vs 2014 Transport capacities for storages points Available Capacities during Summer (TWh) 2013 2014 South-East DEL 16 42 40 22 26 57 47 29 60% 36% 19% 34% South-Atlantique DEL 0 0 0% North-Atlantique DEL 30 33 11% 149 192 29% North B DEL North-East DEL North-West DEL Total 15 Tendency Shippers meeting – 28.01.2014 Comparison summer period 2013 vs 2014 Entry-Exit points capacities Available Capacities during Summer (TWh) 16 Tendency 2013 2014 Dunkerque REC 99 107 8% Taisnières H REC 84 109 31% Obergailbach REC 101 91 -10% Total 284 307 8% Oltingue DEL 43 43 1% Midi REC 17 54 224% Midi DEL 60 71 19% Taisnières B REC 48 42 -13% Shippers meeting – 28.01.2014 Comparison summer period 2013 vs 2014 North-South link capacities Available Capacities during Summer (TWh) North-South link DEL 17 2013 2014 40 52 Shippers meeting – 28.01.2014 Tendency +31% Graphs presenting available capacities on each contractual points 18 Shippers meeting – 28.01.2014 Taisnières B Valves maintenance 19 Shippers meeting – 28.01.2014 Dunkerque Taisnières H counting system (Focus W27) Maintenance compressor (Cuvilly + Fontenay) + Coordianation with Gassco 20 Shippers meeting – 28.01.2014 Taisnières H Taisnières H counting system (Focus W27) 21 Shippers meeting – 28.01.2014 Obergailbach North-East pipe instrumented pigging 22 Shippers meeting – 28.01.2014 Midi DEL (South zone -> TIGF) Roussines maintenance compressor 23 Rhône pipe repairs Shippers meeting – 28.01.2014 Etrez-St Avit pipe repairs Midi REC (TIGF -> South zone) 24 Shippers meeting – 28.01.2014 Oltingue Oltingue annual maintenance 25 Shippers meeting – 28.01.2014 North -
