3 Main changes GRTgaz Maintenance Schedule

4 Main changes: overview Creation of new superpoints Who is impacted by superpoints? Every shipper who has capacities on PIR, PITS or PITTM on our network. Important: The storages are now included in the superpoints. That means more shippers are impacted than before. Introduction of the CPRTt GRTgaz Maintenance Schedule

5 Main changes 4 superpoints with planned restrictions in GRTgaz this summer: SPN3U (formerly SP0003) SPNS1U (formerly SP0004) SPNS2D (new) SPNS3D (new) Dunkerque Dunkerque LNG BELGIUM Virtualys U = Upstream (the entries are restricted) Nord-Est LUX. Amont GERMANY Obergailbach Montoir Nord-Ouest Atlantique NS1 NS2 N3 Oltingue SWITZERLAND ITALIA D = Downstream The exits are restricted Pirineos SPAIN Lussagnet Aval NS3 Sud-Est Fos GRTgaz Maintenance Schedule

6 Main changes A publication only applicable on GRTgaz s network.. For superpoints co-managed with Téréga, each TSO publishes the restriction on its sub-superpoint : SPNS2D -> Restriction published on SSPNS2D (Atl+SE+Montoir+Fos) SPNS3D -> Restriction published on SSPNS3D (Atl+Montoir+Fos) but the same restriction rate for GRTgaz and Téréga s sub-superpoint GRTgaz Maintenance Schedule

8 Main changes CPRTt Capacity available during maintenance when the network is reasonably used. It is based on medium flows and consumption scenarios and do not take into account the uncertainties of works. Restriction rates Are calculateds based on subscribed capacities. For storages and LNG terminals, as the capacities are not booked yet, we assumed that the level of booking is the same as this year. GRTgaz Maintenance Schedule

10 Dates of superpoints activation (summer 2019) SPN3U: 9/09 to 27/09 Impacted points (REC): Virtualys and Obergailbach PIR Montoir Dunkerque Dunkerque LNG N1 Nord-Est Nord-Ouest Atlantique BELGIUM Virtualys LUX. NS1 NS2 Amont N3 GERMANY Obergailbach Oltingue SWITZERLAND SPNS1U: 9/05, 14/06 to 16/06, 28/06 to 26/07, 20/08 to 23/08, 30/09 to 31/10 Impacted points (REC): Virtualys, Obergailbach and Oltingue PIR SSPNS3D: 13/05 to 17/05 27/05 to 27/06 01/07 to 02/08 07/09 to 27/09 30/09 to 06/10 Pirineos SPAIN Lussagnet Aval Sud-Est NS3 Fos ITALIA Impacted point (DEL): Atlantique PITS SSPNS2D: 28/06 to 30/06, 7/10 to 28/10 Impacted points (DEL): Atlantique and South-East PITS GRTgaz Programme travaux

11 The restrictions point by point The following graphs show for each day: Storengy restriction (for storages) GRTgaz restriction directly on the point GRTgaz superpoints restrictions : be careful, the indicated restriction rate does not take into account the superpoint s flexibility; it corresponds to the restriction rate for a monopoint shipper The indicated restriction rates are calculated on the base of: The probably available capacity (CPRTt) The subscribed capacity (last year s for the storages) 4 points are impacted by the superpoints in 2019: PITS South-East and Atlantique, PIR Virtualys et Obergailbach The other points are not impacted by the superpoints; the graphs are shown in the back-up slides. GRTgaz Changements sous T@ TRF & PEG 11

12 South-East PITS Probable restriction rates (based on the CPRTt) on South-East PITS injection capacities (Saline) SSPNS2D: (Atl+SE+Fos+Montoir) Possibility to obtain more UIOLI if LNG in Montoir or Fos + flexibility between Atlantic and South-East + flexibility and UIOLI with Teréga SSP GRTgaz Changements sous T@ TRF & PEG 12

13 Atlantic PITS SSPNS2D: (Atl+SE+Fos+Montoir) Probable restriction rates (based on the CPRTt) on Atlantic PITS injection capacities Possibility to obtain more UIOLI if LNG in Montoir or Fos + flexibility between Atlantic and South-East + flexibility and UIOLI with Teréga SSP SSPNS3D: (Atl + Fos + Montoir) Possibility to obtain more UIOLI if LNG in Montoir or Fos + flexibility and UIOLI with Teréga SSP GRTgaz Changements sous T@ TRF & PEG 13

14 The Atlantic storage can be filled with this maintenance schedule Taking into account Storengy restrictions and GRTgaz PITS and superpoints restrictions, without using the flexibility or additional capacity generated by the superpoints (unfavorable hypothesis).

15 Virtualys and Obergailbach PIR Probable restriction rates (based on the CPRTt) on Virtualys and Obergailbach entry PIRs SPN3U: (Virtualys + Obergailbach) flexibility between the 3 entry points SPNS1U: (Virtualys + Obergailbach+Oltingue) Possibility to obtain more UIOLI if exits in Oltingue + flexibility between the 3 entry points GRTgaz Changements sous T@ TRF & PEG 15

16 How to read the Excel file GRTgaz Maintenance Schedule

17 Example of a client active on Atlantique I booked 10GWh/d of capacities: 1) I need to check which superpoints include Atlantique : SPN1U SPN2U SPN3U SPNS1U SPNS2U SPNS3U SPNS4U SSPNS2D SSPNS3D SPEO1U SPEO2U SSPEO1D SSPEO2D SPSN2D SPSN3D DUNKERQUE OBERGAILBACH OLTINGUE Virtualys FOS MONTOIR Dunkerque GNL Nord-Ouest Nord-Est Atlantique Sud-Est 2) I apply filters to the Excel Maintenance Schedule file: GRTgaz Maintenance Schedule

18 Example of a client active on Atlantique I booked 10GWh of capacities: 1) My relevant restriction rates are: max TRf final = max( max TRf Atlantique ; max TRf SSPNS2D ; max TRf SSPNS3D ) TRf probable final = max( TRf probable Atlantique ; TRf probable SSPNS2D ; TRf probable SSPNS3D ) 2) My effective capacities will be: Example on 27/06 : mincoe = (1 maxtrf) x COS COEprobable = (1 TRfprobable) x COS mincoe = (1-max(30%;54%)) x 10 = 4,6GWh COEprobable = (1-max(30%;51%)) x 10 = 4,9GWh GRTgaz Maintenance Schedule

19 Example of a client active on Virtualys and Obergailbach: 1) I need to check which superpoints include Virtualys and Obergailbach: SPN1U SPN2U SPN3U SPNS1U SPNS2U SPNS3U SPNS4U SSPNS2D SSPNS3D SPEO1U SPEO2U SSPEO1D SSPEO2D SPSN2D SPSN3D DUNKERQUE OBERGAILBACH OLTINGUE Virtualys FOS MONTOIR Dunkerque GNL Nord-Ouest Nord-Est Atlantique Sud-Est 2) Example on 08/07 with a booked capacity of 30GWh on Obergailbach and 10GWh onvirtualys : Obergailbach : mincoe = (1-max(56%;42%)) x 30 = 13GWh SPNS1U : mincoe = (1-42%) x (30+10) = 23GWh Virtualys : mincoe = = 10GWh Virtualys : mincoe = (1-42%) x 10 = 5,8GWh GRTgaz Maintenance Schedule

20 Use of bonuses: Using bonuses increases your capacities on the other points of the superpoint : We consider bonuses : Every exit point for upstream superpoints (Exit PIR and injections in storages) Every entry for downstream superpoints (Entry PIR, PITTM and withdrawals from storages) If a shipper nominates a bonus but don t use the extra capacity, the spare bonus is given as UIOLI to the whole community. Important : Each KWh nominated in the bonus direction gives you an additional KWh to nominate in the restricted direction. GRTgaz Maintenance Schedule

21 Summary & Schedule GRTgaz Maintenance Schedule

22 Summary You also have to take into account the superpoint constraint to know your restriction by point. When a superpoint is active, you can obtain more UIOLI than when the restriction is directly on the point In particular if the «bonus» nominations are large (ex: Oltingue exit for NS1U and Montoir and Fos LNG entries for NS2D et NS3D) GRTgaz Maintenance Schedule
