How to use ECT for maintenance work
Section Maintenance Schedule
Includes all paths and all periods
Includes paths and periods selected by
the shipper

How to use ECT for maintenance work
Total firm capacity which could be
subscribed
Total firm capacity already subscribed Capacities minimum and maximum
available during the maintenance
Restriction rates depends on capacities→ allows to calculate your available capacity in case of restriction1- If CFS is available (after 20th M-1), best information is « Reduction CFS »2- If CFS is not available (before 20th M-1), first information is « Reduction CFC »
Information regarding this
maintenance task
CENTRE ACHEMINEMENTS ET MOUVEMENTS DE GAZDEPARTEMENT GESTION OPERATIONNELLE DES CONTRATS
Important points in 2007
Planned maintenance works vs actual maintenance works assessment: • willingness to keep reliable the initial information
Improving the “design” of ECT data

Work scheduling management
CENTRE ACHEMINEMENTS ET MOUVEMENTS DE GAZDEPARTEMENT GESTION OPERATIONNELLE DES CONTRATS
Obligations & Recommandations
Transmission contract• Best efforts to minimize reduction in capacities• Publication of engineering works schedules at least 2 months in advance• Impact evaluation at least 5 days before engineering work starts
Guidelines from ERGEG• Coordination with other TSO and french Storage & LNG Operator in
order to minimize impact• Publication of the whole program with capacity reductions, at least once
a year
CENTRE ACHEMINEMENTS ET MOUVEMENTS DE GAZDEPARTEMENT GESTION OPERATIONNELLE DES CONTRATS
Main Steps in the engineering works programListing of works • June for the work with the significant impact on capacities• September-October for all works from the Operating Divisions
Schedule planning : October-December• Dialogue with other TSO and french Storage & LNG Operators to coordinate
operations that with have an impacts on the interconnections
Evaluation of capacity availability and validation of programfeasibility : December-January
End of January: first draft of works program sent to shippers• Description of day to day capacity available for each contractual path
Any remarks to be received by the end of February
Reference Works Schedule is official at the beginning of March
CENTRE ACHEMINEMENTS ET MOUVEMENTS DE GAZDEPARTEMENT GESTION OPERATIONNELLE DES CONTRATS
Discussion with shippers
This year we sent the first information on the program in August, followed by 2 other sendings in December and mid-January
Final draft version of the work schedule sent at the end of January
GRTgaz’s expectations• Remarks and questions from shippers in february => possibility to organize
bilateral meetings (call your operational usual contact)• Important in case of adaptation needed• Difficulties to adapt the program after the beginning of march
CENTRE ACHEMINEMENTS ET MOUVEMENTS DE GAZDEPARTEMENT GESTION OPERATIONNELLE DES CONTRATS
Coordination
Meeting with adjacent operators• Between october and december year N-1• Storage and LNG terminal operator : several working meetings are required• Gassco• Fluxys• Eon Gas Transport• Transitgas• TIGF

Method of evaluation of capacityrestrictions
CENTRE ACHEMINEMENTS ET MOUVEMENTS DE GAZDEPARTEMENT GESTION OPERATIONNELLE DES CONTRATS
Principle used to calculate capacity
The tariff scheme represents the physicalconstraints on the network
Contractual capacity is a maximum flow in a pipe or the sum of flows in several pipes
A capacity is associated with a set direction

Principle used to calculate capacity
Capacity depends on:• Upstream and downstream saturation• consumption• nominations
Firm capacity :• is calculated with the most restrictive scenario, for consumption and
nominations• To determine the flow guaranted in all circumstances excepted works
and « force majeure »
Interruptible capacity:• Corresponds to the technical limits under favourable situation

How to distribute the capacity restrictions ?
Order of priority :• Links• Entry points• Transport Storage Interface Points
The aim of distributing impact is :• To minimize the inconvenience caused by the work• To maximize flows• To conduct works in good conditions
The same restriction rate is applied to all the shippers

Prospects
Customers input and feedback
GRTgaz sells a commodity but is also an industrial company
The constraints are becoming even tougher• Changes in French rules • Heavy investments in the network
We are looking at all ideas to reduce impacts• Reduce physical impacts • Design of the Sales offering • Level of Information to manage the restrictions• ….
