Summary & schedule

Agenda

GRTgaz │ Maintenance Schedule 2019 2


Main changes


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.

• Introduction of the CPRTt

Important: The storages are now included in the superpoints.

That means more shippers are impacted than before.


Main changes

4 superpoints with planned restrictions in GRTgaz this summer:

• SPN3U (formerly SP0003)

• SPNS1U (formerly SP0004)

• SPNS2D (new)

• SPNS3D (new)

U = Upstream

(the entries are restricted)

D = Downstream

The exits are restricted

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

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 │ Changements sous T@ – TRF & PEG 11

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.

The restrictions point by point


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


Atlantic PITS


on Atlantic PITS injection capacities

SSPNS3D: (Atl + Fos + Montoir)

+ flexibility and UIOLI with Teréga SSP

Taking into account Storengy restrictions and GRTgaz PITS and

superpoints restrictions, without using the flexibility or additional capacity

generated by the superpoints (unfavorable hypothesis).

The Atlantic storage can be filled

Example of a client active on Atlantique

I booked 10GWh/d of capacities:

1) I need to check which superpoints include Atlantique :

2) I apply filters to the Excel Maintenance Schedule file:


Example of a client active on Atlantique

I booked 10GWh of capacities:

1) My relevant restriction rates are:

max𝑇𝑅𝑓𝑓𝑖𝑛𝑎𝑙 = max(max𝑇𝑅𝑓𝐴𝑡𝑙𝑎𝑛𝑡𝑖𝑞𝑢𝑒; max𝑇𝑅𝑓𝑆𝑆𝑃𝑁𝑆2𝐷; max𝑇𝑅𝑓𝑆𝑆𝑃𝑁𝑆3𝐷)

𝑇𝑅𝑓 𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑒𝑓𝑖𝑛𝑎𝑙 = max( 𝑇𝑅𝑓 𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑒𝐴𝑡𝑙𝑎𝑛𝑡𝑖𝑞𝑢𝑒; 𝑇𝑅𝑓 𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑒𝑆𝑆𝑃𝑁𝑆2𝐷; 𝑇𝑅𝑓 𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑒𝑆𝑆𝑃𝑁𝑆3𝐷)

2) My effective capacities will be:

𝑚𝑖𝑛𝐶𝑂𝐸 = (1 − 𝑚𝑎𝑥𝑇𝑅𝑓) 𝑥 COS𝐶𝑂𝐸𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑒 = (1 − 𝑇𝑅𝑓𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑒) 𝑥 COS

Example on 27/06 :

minCOE = (1-max(30%;54%)) x 10 = 4,6GWh

COEprobable = (1-max(30%;51%)) x 10 = 4,9GWh

Example of a client active on Virtualys

and Obergailbach:1) I need to check which superpoints include Virtualys and Obergailbach:

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 = 23 - 13 = 10GWhVirtualys : minCOE = (1 - 42%) x 10 = 5,8GWh


Use of bonuses:

Important : Each KWh nominated in the bonus direction gives you an additional

KWh to nominate in the restricted direction.

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.


Summary & Schedule

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)
