Generality on nomination process

Several steps in the nomination process
With Single Nomination, management of most of the constraints in SAM
Storengy Maintenance: through the Daily Available Capacity (step Provisionally Scheduled)
GRTgaz maintenance and restrictions
On the PITS level: through the integration of the Effective Technical Capacity (CTE) at 1:50 pm.
All the following scheduling are in line with this transport constraint (step Scheduled)

Restricted capacities
Entitled Definition Publication
CMNTt Technical minimum capacity available in the event of
engineering works.
At last 60 days before (1st)
Can decrease until DW-5
Can increase until D-1
CPRTt Probably capacity available in the event of works. At last 60 days before (1st)
Can increase until D-1
CTE Technical effective capacity.
Its the actual total technical capacity on a PCR that GRTgaz
can actually guarantee to all shippers per Gas Day. It can differ
from the CTN* in the event of restrictions.
On D-1 before 2 pm
Can increase until the beginning of the Gas
Day in case of the end of works.
COSf Firm capacity subscribed by all shippers for a Gas Day -
Max TRf Maximal firm flow restriction
Max TRf = 1 – CMNTt / COSf
At last 60 days before (1st)
Can decrease until DW-5
Can increase until D-1
Probable TRf Probable firm flow restriction
Probable TRf = 1 – CPRTt / COSf
At last 60 days before (1st)
Can increase until D-1
15
Reductions of capacities caused by works are published in the GRTgaz work program*.
The following values are published:
* - http://www.grtgaz.com/en/acces-direct/customer/supplier-trader/works.html
March 27, 2019 Maintenances & Restrictions Webinar
Restricted capacities
The CMNTt* represents the technical minimum capacity available in the event of works.
Its calculation is based on a situation of extreme network requests in terms of
consumption and programming of flows. It also integrates a reasonable estimation of
potential hazards of the works.
The CPRTt* gives a good view of the available capacity on a situation of reasonable
network requests. More exactly, its based on median consumptions and flows scenario
and takes now into account probabilities on works.
Before 2:00 pm on D-1, CTE* value gives the final capacity available from GRTgaz for
Day D.
From DW-5, the CTE cannot be lower than the CMNTt. However, CTE can be higher
than the CPRTt if the conditions make it possible.

Restriction rates
From 19th of March 2019 GRTgaz republish the PITS
restriction rates on Trans@ctions*.
Moreover restriction rates remain available for consultation
on Smart GRTgaz.
These restrictions rates are only the GRTgaz vision and are
calculated with the operational subscribed capacities.

Locational spread is contracted even if
not successful!
- The locational spread launched at H is not successful
- AND the alert level is still red at H+1
No other locational spread is launched if the former one is not successful!
Mutualised restriction is activated only if the locational spread is not sufficient

Mutualised restriction principles
54
As a last resort, within the day, should the call to the market via thelocational spread not be effective
No financial compensation in the event of use of this mechanism
Partial interruption of firm capacities:
▪ pro rata to the subscribed capacities
▪ mutualised on a group of points called superpoint, in order to give flexibility to theshippers
