Only shippers that have not signed it during the First Phase will be required to sign the NDA. Capacity booking contracts and/or transmission contracts Similar to the Capacity booking contracts and/or transmission contracts for 2013 capacities, to be approved by NRAs adapted to the capacity products offered for Private contracts between TSOs Action foreseen Non-Disclosure Agreement between TSOs No changes required. No need to sign a new document. Memorandum of Understanding between TSOs Amendment required to launch the Second Phase. “The Parties undertake to complete and update the indicative lists of infrastructure developments for the 2015 Project before the launch of the second phase including the binding requests of the 2015 Project. The final list will be contractualised by way of an amendment to the present MoU. The Parties shall execute this amendment no later than March 31st, 2010.”

8 Proposal on Capacities at the border to be included in the Second Phase 3

Capacities – Non-sold 2013 Capacities “In the second phase, the sale of capacities not sold during the first phase could be possibly* provided NRAs’ prior approval and subject to the frame required by the NRAs if any.” The Information Memorandum states: (*) Note that due to a typo the original document reads “possible” instead of “possibly

The conversion to bcm/y is merely informative.

12 Having taken into consideration the results from the First Phase and comments received by stakeholders after the announcement of the First Phase results, TSOs have agreed on the general principle of maximising capacity allocation in order to attend as much market demand as possible. This implies that:  MIDCAT should be analysed or built if there is enough capacity to proceed; and  The Biriatou project should be included in the capacity offering of the Second Phase, and it must be analysed both in case of insufficient or excess demand for validating MIDCAT. The timing for Biriatou capacities would need to be reconsidered, according to the new dates for the FID. The agreement has been reached considering both proposals together (capacities to be included + maximisation of capacity allocation), as well as the agreement to attach to the calendar included in the Information Memorandum. General principles agreed by TSOs

14 The Information Memorandum states: “Remaining capacity not sold via the current procedure at the Spanish-French border will be sold through coordinated procedures between French and Spanish TSOs to be defined. In France, the detailed rules for marketing this capacity will be submitted to CRE for approval. In Spain, capacity allocation will comply with regulation in force.” Non-sold 2013 Capacities not corresponding to Biriatou

(*) Total capacities showed in the Information Memorandum included Larrau and Biriatou TSOs proposal Potential inclusion in the Second Phase: to be discussed

16 Proposal on the Test by Regulators to validate capacity allocation for the Second Phase 4

17  It would be recommendable for the Second Phase to announce a Test commonly agreed by Regulators (CRE and CNE).  The validation mechanism of such Test should guarantee that if a project enjoys 100% of demand for the capacity offered on a long-term basis in only one direction, the validation by Regulators should be automatic. The threshold for studying the project could be placed around 50%.  Demand during the First Phase for both 2013 capacities (binding requests) and 2015 capacities (indicative requests) has revealed a clear preference for capacity at the border from South to North (Spain-France). The Test should be primarily performed on demand for such (forward flow) capacity.  If a project enjoys less than 100% of demand from South to North, a validation by regulators may also be granted taking into account other conditions, e.g:  (Certain level of) demand from North to South (backhaul flow).  SoS criteria (e.g. in line with future SoS Regulation).  … Proposals on the Test agreed by TSOs

18 In practice the proposal to build MIDCAT if there is enough capacity to proceed could be articulated in two different manners: 1.MIDCAT should be considered first, and regardless the result of the analysis, Biriatou should be considered after MIDCAT. A threshold test for each project could be established independently. 2.Demand thresholds could be predefined, in order for regulators to provide visibility on the validation of the allocation. Under this proposal, the practical result should be similar to the one of the previous proposal. Proposals on the Test agreed by TSOs

Capacities – capacity splitting  Two options were proposed at the cross border point between Spain and France :  Option 1: Three-step entry-exit system Spain ↔ TIGF ↔ GRTgaz South (Points C & D)  Option 2: Entry-exit system with direct interconnection Enagas ↔ GRTgaz South (Points A & B)  Aggregating the options presented, demand for 2015 capacities at the cross border point between Spain and France equals 85.6% of the capacities offered from South to North, and 69.1% from North to South.

26 “Shippers will be asked in the non-binding phase which capacity product they want. This input will be used to define a split between the 3 components* in the France – Spain products.” The Information Memorandum states: Capacity splitting (*) GRTgaz South Spain, GRTgaz South-TIGF and TIGF-Spain, the three of them in both directions.
