Pilot Project on Market CouplingPEG Nord / PEG Sud
3rd Workshop on Gas Target ModelLondon
11 APRIL 2011
Preliminary note
• GRTgaz and Powernext are actively working on the Target Model as well as on the market coupling pilot project in France. GRTgaz and Powernext believe that Market Coupling is only one of the many topics to be covered by discussions related to the Target Model, such as the optimal size of market areas, consistency of long term and short term mechanisms, price signals for the development of new interconnection capacities…
• GRTgaz and Powernext hope that this presentation will in any case contribute to the design of the future organization of the European gas market
A need for a large French hub
• French hubs under fast development
• Market participants almost unanimous:– Need for a single French hub – In the short term:
• Need for solutions to better connect market zones by optimizing capacity utilization
• Need to increase market liquidity and access to zone Sud
CONTEXT
Current situation
• PEG Sud less liquid than PEG Nord

Different options to create a single Hub
• Full zone merging– Either via significant investments– Or via a combination of investments (including reinforcement of the
core network on North and South market areas) and contractual arrangements (such as flow commitments) A mid to long term option (2016) due to the necessary investments
• Enhanced connection of existing zones– Via market coupling between PEG Nord and PEG Sud, thanks to a pilot
project initiated by Powernext and GRTgaz
MARKET COUPLING EXPERIMENTATIONPEG NORD / PEG SUD
A market coupling project suitable for gas business
• Continuous trading of gas : main differences between gas and electricity– Gas supply is far more flexible than in electricity as it is
storable• No need for production plant call in advance as in electricity;
access to storage, LNG terminals, etc.• Daily balancing regime in France
no need for auctions: continuous trading of gas is the standard organization of the market and better adapted to its needs
Main design issues
• One single French hub as a long term objectiveIn the short term, better connection of markets and optimization of capacity utilization
Easy and flexible mechanism that can be implemented rapidly …
… that makes available to the market unsold capacities at market price …
…and keep gas flexibilities

Need
Context and
constraints
Questions
Solution
Design a market coupling mechanism adapted to gas :- Capacity dedicated to the pilot project ?- Mechanism for allocating capacity ?- Products to be marketed ?
Capacity dedicated to the pilot project
• For this experimentation, it was decided to dedicate 10 GWh/d of day-ahead firm capacity in both directions (5% of total firm capacity)
– This capacity was unsold after the Open Subscription Period for annual capacity, it will not be made available through any other short term product (monthly, daily) other than market coupling
– The mechanism does not rely on sold unused capacity (no restriction of re-nomination rights)
Mechanism for capacity allocation
• 3 mechanisms were studied and discussed in order to allocate the available capacity:1. Through an explicit auction of capacities on an ad-hoc platform2. Through an auction of gas molecule, combined with implicit
allocation of capacities3. Through a defined time window where all market participants
can disclose their needs (continuous trading) which will be matched with available capacities at a random time
• The third mechanism has been chosen because it can be integrated within continuous trading, which is the standard organization for the gas market
Products to be marketed• Capacity rights or spread products?
– Trading capacity rights needs property transfer while trading spread products does not
• Spread products are:– Easier to trade and manage for participants (Trayport technology –
standard in the gas sector)– Easier to implement for GRTgaz and Powernext– More flexible (participants can valuate all their flexibility means in
spreads: storage, transport, etc.)– Identical to capacity rights on Day-Ahead products as there are no
maintenance risks
Capacities will be made available by GRTgaz through spread products on the Powernext screen
Products to be marketed
• What is a spread product?

Market coupling mechanism• One window during the core period of Powernext of 15 minutes when matching of
GRTgaz unsold capacities and best orders happens– This mechanism is equivalent to an implicit auction embedded into the continuous trading
platform without implying any change in the market participants habits (except for spread orders which are directly posted – which is an additional possibility)

Market coupling mechanism
• Automatic matching of GRTgaz available capacities– Corresponds to selling North to South (or South to North) gas flows at
a decreasing market price according to the order book– Allows to match offer and demand between both virtual trading points– Should facilitate price convergence (to be confirmed by the
experimentation)– Should improve the global liquidity of both market zones (to be
confirmed by the experimentation)
Project planning
January February March April May June July August September2011
GRTgaz starts its interventions on Powernext spread contracts
CRE’s deliberation on market coupling project
Launch of PegSud/PegNord spread contracts on Powernext
Assessment of the coupling
mechanism and improvements
Conclusions
• It is possible to design a market coupling mechanism, which is suitable to the specific organization of the gas market and of gas exchanges (continuous booking).
• A pilot project will be implemented in the coming weeks between PEG Nord and PEG Sud : this pilot project should help enhancing liquidity, fostering price convergence and optimizing capacity utilization
• Market coupling is viewed as an interim step before merging existing market zones
