            COMMISSION REGULATION (EU) No 984/2013
of 14 October 2013
         
establishing a Network Code on Capacity Allocation Mechanisms in Gas Transmission Systems and supplementing Regulation (EC) No 715/2009 of the European Parliament and of the Council
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EC) No 715/2009 of 13 July 2009 of the European Parliament and of the Council on conditions for access to the natural gas transmission networks and repealing Regulation (EC) No 1775/2005 (1), and in particular Article 6(11) thereof,

Whereas:







(1)


Regulation (EC) No 715/2009 sets non-discriminatory rules for access conditions to natural gas transmission systems with a view to ensuring the proper functioning of the internal market in gas.












(2)


Duplication of gas transmission systems is in most cases neither economic nor efficient. Competition in natural gas markets therefore requires a transparent and non-discriminatory access to gas infrastructure for all network users. However, in large parts of the Union the lack of equal and transparent access to transmission capacity remains a major obstacle for achieving effective competition on the wholesale market. Furthermore, the fact that national rules differ from one Member State to another hampers the creation of a well-functioning internal market for gas.












(3)


Inefficient use of and limited access to the Union’s high-pressure gas pipelines lead to suboptimal market conditions. A more transparent, efficient and non-discriminatory system of allocation of scarce transmission capacities needs to be implemented for the Union’s high-pressure gas grids, so that cross-border competition can further develop and market integration can progress. Developing such rules has been consistently supported by stakeholders.












(4)


Bringing about effective competition between suppliers from inside and outside the Union requires that they are able to flexibly use the existing transmission systems to ship their gas according to price signals. Only a well-functioning network of interconnected transmission grids, offering equal access conditions to all, allows gas to flow freely across the Union. That in turn attracts more suppliers, increasing liquidity at the trading hubs and contributing to efficient price discovery mechanisms and consequently fair gas prices that are based on the principle of demand and supply.












(5)


This Regulation establishing a network code on capacity allocation mechanism in gas transmission systems aims to establish the necessary degree of harmonisation across Europe. The effective implementation of this Regulation furthermore relies on the introduction of tariff systems which are consistent with the capacity allocation mechanisms proposed in this Regulation, to ensure the implementation without detrimental effect on the revenues and cash flow positions of transmission system operators.












(6)


This Regulation has been adopted on the basis of Regulation (EC) No 715/2009 which it supplements and of which it forms an integral part. References to Regulation (EC) No 715/2009 in other legal acts shall be understood as also referring to this Regulation. This Regulation does not apply to natural gas transmission systems situated in Member States for the duration of derogations granted under Article 49 of Directive 2009/73/EC of the European Parliament and of the Council (2). This Regulation does apply to non-exempted capacities in major new infrastructures which have received an exemption from Article 32 of Directive 2009/73/EC or from the former Article 18 of Directive 2003/55/EC of the European Parliament and of the Council (3) to the extent the application of this Regulation does not undermine such an exemption and taking into account the specific nature of interconnectors when bundling.












(7)


This Regulation was established according to the procedure as set out in Article 6 of Regulation (EC) No 715/2009. It further harmonises the rules laid down in Article 16 of Regulation (EC) No 715/2009 and supplements the principles of capacity allocation mechanisms and congestion management procedures concerning transmission system operators as laid down in point 2.1 of Annex I to Regulation (EC) No 715/2009.












(8)


This Regulation is without prejudice to application of EU and national competition rules, in particular the prohibitions of restrictive agreements (Article 101 of the Treaty on the Functioning of the European Union) and of abuse of a dominant position (Article 102 of the Treaty on the Functioning of the European Union). The capacity allocation mechanisms put in place should be designed in such a way as to avoid foreclosure of downstream supply markets.












(9)


This Regulation is without prejudice to public service obligations of a transmission system operator in accordance with Article 3 of Directive 2009/73/EC.












(10)


The measures provided for in this Regulation are in accordance with the opinion of the Committee established pursuant to Article 51 of Directive 2009/73/EC.












(11)


National regulatory authorities and transmission system operators should have regard to best practices and endeavours to harmonise processes for the implementation of this Regulation. Acting in accordance with Article 7 of Regulation (EC) No 713/2009 of the European Parliament and of the Council (4) the Agency and the national regulatory authorities should ensure that capacity allocation mechanisms are implemented at the applicable interconnection points across the Union in the most effective way.





HAS ADOPTED THIS REGULATION:



CHAPTER I


GENERAL PROVISIONS



Article 1

Subject matter

This Regulation establishes a Network Code setting up standardised capacity allocation mechanisms in gas transmission systems. The standardised capacity allocation mechanism shall include an auction procedure for relevant interconnection points within the Union and the standard cross-border capacity products to be offered and allocated. This Regulation shall set out how adjacent transmission system operators cooperate in order to facilitate capacity sales, having regard to general commercial as well as technical rules related to capacity allocation mechanisms.

CHAPTER II


PRINCIPLES OF COOPERATION



Article 4

Coordination of maintenance

Where maintenance of a pipeline or part of a transmission network has an impact on the amount of transmission capacity which can be offered at interconnection points, the transmission system operator(s) shall fully cooperate with their adjacent transmission system operator(s) regarding their respective maintenance plans in order to minimise the impact on potential gas flows and capacity at an interconnection point.


Article 5

Standardisation of communication


1.   Transmission system operators shall coordinate the implementation of standard communication procedures, coordinated information systems and compatible electronic on-line communications such as shared data exchange formats and protocols, as well as agree principles as to how this data is treated.


2.   Standard communication procedures shall include, in particular, those relating to network users’ access to the transmission system operators’ auction system or a relevant booking platform and the review of auction information provided. The timing and content of the data to be exchanged shall be compliant with the provisions set out in Chapter III.


3.   The standard communication procedures adopted by transmission systems operators shall include an implementation plan and duration of applicability, which shall be in line with the development of booking platform(s) as set out in Article 27. Transmission systems operators shall ensure confidentiality of commercially sensitive information.



Article 6

Capacity calculation and maximisation


1.   The maximum technical capacity shall be made available to network users, taking into account system integrity, safety and efficient network operation.






(a)


In order to maximise the offer of bundled capacity through the optimization of the technical capacity transmission system operators shall take the following measures at interconnection points, giving priority to those interconnection points where there is contractual congestion pursuant to point 2.2.3(1) of Annex I to Regulation (EC) No 715/2009: 4 February 2015, the transmission system operators shall establish and apply a joint method, setting out the specific steps to be taken by the respective transmission system operators to achieve the required optimization:






(1)


the joint method shall include an in-depth analysis of the technical capacities, including any discrepancies therein on both sides of an interconnection point, as well as the specific actions and detailed timetable – including possible implications and containing the regulatory approvals required to recover costs and adjust the regulatory regime – necessary to maximize the offer of bundled capacity. Such specific actions shall not be detrimental to the offer of capacity at other relevant points of the concerned systems and points to distribution networks relevant for security of supply to final customers, such as those to storages, LNG terminals and protected customers as defined in Regulation (EU) No 994/2010 of the European Parliament and of the Council (5). This in-depth analysis should take into account assumptions made in the Union-wide ten-year network development plan pursuant to Article 8 of Regulation (EC) No 715/2009, national investment plans, relevant obligations under the applicable national laws and any relevant contractual obligations;










(2)


the relevant transmission system operators shall apply a dynamic approach to re-calculating technical capacity, where appropriate in conjunction with the dynamic calculation applied for additional capacity on the basis of point 2.2.2(2) of Annex I to Regulation (EC) No 715/2009, jointly identifying the appropriate frequency for re-calculation per interconnection point and having regard to the particular specificities thereof;










(3)


adjacent transmission system operators shall include other transmission system operators specifically affected by the interconnection point in the joint method;










(4)


transmission system operators shall have regard to information that network users may provide with regard to expected future flows when re-calculating the technical capacity.














(b)


the transmission system operators shall jointly assess at least the following parameters and where appropriate adjust them:






(1)


pressure commitments;










(2)


all relevant demand and supply scenarios, including details on reference climatic conditions and network configurations associated with extreme scenarios;










(3)


calorific value.










2.   Where the optimisation of technical capacity causes costs to the transmission system operators, particularly costs that unevenly impact transmission system operators on either side of an interconnection point, transmission system operators shall be allowed to recover such efficiently incurred costs via the regulatory framework established by the relevant regulatory authorities in accordance with Article 13 of Regulation (EC) No 715/2009 or Article 42 of Directive 2009/73/EC. Article 8(1) of the Regulation (EC) No 713/2009 shall apply.


3.   Where appropriate, national regulatory authorities shall consult network users on the applied calculation method and joint approach.


4.   Changes in the amount of bundled capacity offered at interconnection points as a result of the process pursuant to paragraph 1 shall be included in the report of the Agency published pursuant to point 2.2.1(2) of Annex I to Regulation (EC) No 715/2009.



Article 7

Exchange of information between adjacent transmission system operators


1.   Adjacent transmission system operators shall exchange nomination, re-nomination, matching and confirmation information at relevant interconnection points on a regular basis.


2.   Adjacent transmission system operators shall exchange information about the maintenance of their individual transmission network in order to contribute to the decision making process with regard to the technical use of interconnection points. The procedures to exchange data between transmission system operators shall be integrated in their respective interconnection agreement.




CHAPTER III


ALLOCATION OF FIRM CAPACITY



Article 8

Allocation methodology


1.   Auctions shall be used for the allocation of capacity at interconnection points.


2.   At all interconnection points the same auction design shall apply. The relevant auction processes shall start simultaneously for all concerned interconnection points. Each auction process, relating to a single standard capacity product, shall allocate capacity independently of every other auction process except where, subject to the agreement of the directly involved transmission system operators and the approval of relevant national regulatory authorities, competing capacity is allocated.


3.   The standard capacity products shall follow a logical order by which products covering yearly capacity shall be offered first, followed by the product with the next shortest capacity duration for use during the same period. The timing of the auctions provided for in Articles 11 to 15 shall be consistent with this principle.


4.   The rules on standard capacity products as set out in Article 9 and auctions as set out in Articles 11 to 15 shall apply to bundled capacity and unbundled capacity at an interconnection point.


5.   For a given auction, the availability of the relevant standard capacity products shall be communicated in accordance with Articles 11 to 15 and according to the auction calendar.


6.   An amount at least equal to 20 % of the technical capacity at each interconnection point shall be set aside and offered in accordance with paragraph 7, provided that the available capacity, at the time this Regulation enters into force, is equal to or greater than the proportion of technical capacity to be set aside. If the available capacity, at the time this Regulation enters into force, is less than the proportion of technical capacity to be set aside, the whole of any available capacity shall be set aside. This capacity shall be offered in accordance with paragraph 7(b), while any remaining capacity set aside shall be offered in accordance with paragraph 7(a).


7.   Any capacity set aside pursuant to paragraph 6 shall be offered, subject to the following provisions:






(a)


an amount at least equal to 10 % of the technical capacity at each interconnection point shall be offered no earlier than in the annual yearly capacity auction as provided for in Article 11 held in accordance with the auction calendar during the fifth gas year preceding the start of the relevant gas year; and










(b)


a further amount at least equal to 10 % of the technical capacity at each interconnection point shall first be offered no earlier than the annual quarterly capacity auction as provided for in Article 12, held in accordance with the auction calendar during the gas year preceding the start of the relevant gas year.






8.   In the case of new capacity, an amount at least equal to 10 % of the technical capacity at each interconnection point shall be set aside and offered no earlier than the annual quarterly capacity auction as provided for in Article 12, held in accordance with the auction calendar during the gas year preceding the start of the relevant gas year.


9.   The exact proportion of capacity to be set aside in relation to paragraphs 6 and 8 shall be subject to a stakeholder consultation, alignment between transmission system operators and approval by national regulatory authorities at each interconnection point. National regulatory authorities shall in particular consider setting aside higher shares of capacity with a shorter duration to avoid foreclosure of downstream supply markets.



Article 9

Standard capacity products


1.   Transmission system operators shall offer yearly, quarterly, monthly, daily and within-day standard capacity products.


2.   Yearly standard capacity products shall be the capacity, which may be applied for, in a given amount, by a network user for all gas days in a particular gas year (starting on the 1st of October).

4.   Monthly standard capacity products shall be the capacity, which may be applied for, in a given amount, by a network user for all gas days in a particular calendar month (starting on the 1st day of each month).


5.   Daily standard capacity products shall be the capacity, which may be applied for, in a given amount, by a network user for a single gas day.


6.   Within-day standard capacity products shall be the capacity, which may be applied for, in a given amount, by a network user from a start time within a particular gas day until the end of the same gas day.

5.   In order for network users to participate in an auction, it shall be mandatory to place a volume bid in the first bidding round.


6.   Transmission system operators shall provide network users with the option to enter bids automatically against any price step.


7.   Once the relevant bidding round closes, no modification, withdrawal or variation to valid bids shall be accepted. All valid bids shall become binding commitments of a network user to book capacity to the amount requested per announced price, provided the clearing price of the auction is that announced in the relevant bidding round.


8.   The volume bid in any bidding round per network user shall be equal or smaller to the capacity offered in a specific auction. The volume bid per network user at a specific price shall be equal to or less than the volume bid placed by this network user in the previous round, except where paragraph 16 applies.


9.   Bids may be freely entered, modified and withdrawn during a Bidding Round, providing all bids comply with paragraph 8. Valid bids shall remain valid until modified or withdrawn.


10.   A large price step and a small price step shall be defined per interconnection point and per standard capacity product and published in advance of the relevant auction. The small price step shall be set such that an increase by an integer number of small price steps is equal to an increase by a large price step.


11.   The determination of the large price step shall seek to minimise, as far as reasonably possible, the length of the auction process. The determination of the small price step shall seek to minimise, as far as reasonably possible, the level of unsold capacity where the auction closes at a price higher than the reserve price.


12.   If the aggregate demand across all network users is less than or equal to the capacity offered at the end of the first bidding round, the auction shall close.


13.   If the aggregate demand across all network users is greater than the capacity offered at the end of the first bidding round or a subsequent bidding round, a further bidding round shall be opened with a price equal to the price in the previous bidding round, plus the large price step.


14.   If the aggregate demand across all network users is equal to the capacity offered at the end of the second bidding round or a subsequent bidding round, the auction shall close.


15.   If a first time undersell occurs, a price reduction shall take place and a further bidding round shall be opened. The further bidding round will have a price equal to the price applicable in the bidding round preceding the first time undersell, plus the small price step. Further bidding rounds with increments of the small price step shall then be opened until the aggregate demand across all network users is less than or equal to the capacity offered, at which point the auction shall close.


16.   The volume bid per network user in the first bidding round where small price steps are applied shall be equal to or less than the volume bid placed by this network user in the bidding round which preceded the first-time undersell. The volume bid per network user in all bidding rounds where small price steps are applied shall be equal to or greater than the volume bid placed by this network user during the bidding round in which the first-time undersell occurred.


17.   If the aggregate demand across all network users is greater than the capacity offered in the bidding round with a price equal to that which led to the first time undersell, minus one small price step, the auction shall close. The clearing price shall be the price that led to the first time undersell and the successful bids shall be those submitted during the original bidding round in which the first time undersell occurred.


18.   After each bidding round, the demand of all network users in a specific auction shall be published as soon as reasonably possible in an aggregated form.


19.   The price announced for the last bidding round in which the auction closes shall be considered as the clearing price of the specific auction, except cases where paragraph 17 applies.


20.   All network users who have placed valid volume bids at the clearing price are allocated the capacity according to their volume bids at the clearing price. Successful network users shall pay the clearing price of the specific auction, which may be a fixed or a variable price as set out in Article 26(2), and any other possible charges applicable at the time when the capacity allocated to them can be used.


21.   Following every closed auction, the final auction result including the aggregation of allocated capacities and the clearing price shall be published. Successful network users shall be informed about the amount of capacities they are allocated, individual information shall be communicated only to concerned parties.


22.   If an ascending clock auction has not ended by the scheduled starting point (according to the auction calendar) of the next auction for capacity covering the same period, the first auction shall close and no capacity shall be allocated. The capacity shall be offered in the next relevant auction.



Article 18

Uniform-Price auction algorithm


1.   In a uniform price auction, there is a single bidding round in which the network user bids price as well as quantity.


2.   During the bidding round of a given auction, network users may submit up to 10 bids. Each bid shall be treated independently from other bids. After the closure of the bidding round, remaining bids may not be amended or withdrawn.


3.   A bid shall specify:






(a)


the identity of the network user applying;










(b)


the concerned interconnection point and direction of the flow;










(c)


the standard capacity product for which the capacity is applied for;










(d)


the amount of capacity for the respective standard capacity product applied for;










(e)


the minimum amount of capacity for the respective standard capacity product which the network user is willing to be allocated according to the relevant algorithm in case the network user is not allocated the amount requested in accordance with point (d);










(f)


the bid prices, which shall not be less than the reserve price applicable for the relevant standard capacity product, which the network user is willing to pay in respect of the capacity applied for. Bids with a bid price below the reserve price shall not be accepted.






4.   The transmission system operator shall rank all bids relating to a given standard capacity product according to their bid price, the highest price ranking first.


5.   All remaining bids at bidding round closing time shall be considered as binding on those network users that are allocated at least the minimum amount of capacity requested in accordance with point (e) of paragraph 3.


6.   Following the ranking of the bids in accordance with paragraph 4, and subject to paragraphs 7 to 10, capacity shall be allocated to the bids in function of their price ranking. All bids for which capacity is allocated shall be considered as successful. After the allocation of capacity, the remaining unallocated capacity shall be reduced by such quantity.


7.   Following the application of paragraph 6 and subject to paragraph 9, where the amount of capacity bid for by a network user exceeds the remaining unallocated capacity (after capacity has been allocated to network users placing higher bids), this network user shall be allocated capacity equal to the remaining unallocated capacity.


8.   Following the application of paragraph 7 and subject to paragraph 9, where each of two or more bids specifies the same bid price, and the amount of relevant capacity remaining applied for in aggregate under such bids exceeds the remaining unallocated amount, the remaining unallocated amount shall be allocated pro rata to the amounts applied for in each such bid.


9.   Where the amount to be allocated in respect of a bid pursuant to paragraph 6, 7 or 8 is less than the minimum amount of capacity according to paragraph 3(e), the bid shall be disregarded and become null and void, and a revised allocation shall be made between remaining equal price bid(s) under paragraph 8, or (as the case may be) an allocation shall made in respect of the next priced bid, pursuant to paragraph 6.


10.   Where the remaining amount to be allocated in respect of any bid pursuant to paragraphs 6, 7, 8 or 9 is equal to zero no further capacity shall be allocated to the remaining bids. Those bids shall be considered unsuccessful.


11.   The clearing price shall be defined as the price of the lowest successful bid, if the demand exceeds the offer at the reserve price. In all other cases, the clearing price shall be equal to the reserve price. Successful network users shall pay the clearing price of the specific auction, which may be a fixed or a variable price as set out in Article 26(2) and any other possible charges applicable at the time when the capacity allocated to them can be used.




CHAPTER IV


BUNDLING OF CROSS-BORDER CAPACITY



Article 19

Bundled Capacity products

Adjacent transmission system operators shall jointly offer bundled capacity products, according to the following principles:






(1)


on both sides of an interconnection point all firm capacity shall be offered as bundled capacity, in so far as there is available firm capacity on both sides of the interconnection point:










(2)


transmission system operators shall offer capacity for the relevant standard capacity product on a booking platform, in accordance with Article 27 and in accordance with the applicable allocation procedure, as set out in Chapter III;










(3)


the bundled capacity to be offered by the transmission system operators concerned at an interconnection point shall be contracted through a single allocation procedure;










(4)


network users shall comply with applicable terms and conditions of the transport contract(s) of the transmission system operators concerned as from the time the transport capacity is contracted;










(5)


where there is more available firm capacity on one side of an interconnection point than on the other side for any period considered, the transmission system operator with the most available firm capacity may offer such extra capacity to the network users as an unbundled product in accordance with the auction calendar and the following rules:






(a)


where there is an existing unbundled transport contract at the other side of the interconnection point, capacity may be offered on an unbundled basis not exceeding the amount and duration of the existing transport contract at the other side;










(b)


where such extra capacity would not fall under paragraph 5 (a), it may be offered for a maximum period of one year;














(6)


any unbundled capacity allocated in accordance with paragraph 5 may be used and nominated as such. It may also be traded on the secondary market;










(7)


adjacent transmission system operators shall establish a joint nomination procedure for bundled capacity, providing network users with the means to nominate the flows of their bundled capacity via a single nomination;










(8)


the obligations to offer bundled capacity also apply, to the extent that they are relevant, to secondary capacity markets. Without prejudice to paragraph 1, capacity originally allocated as bundled capacity can only be resold as bundled capacity on the secondary market;










(9)


where two or more interconnection points connect the same two adjacent entry-exit systems, the adjacent transmission system operators concerned shall offer the available capacities at the interconnection points at one virtual interconnection point. In case more than two transmission system operators are involved because capacity in one or both entry-exit systems is marketed by more than one transmission system operator, the virtual interconnection point shall include all of these transmission system operators, to the extent possible. In all cases a virtual interconnection point shall be established only if the following conditions are met:






(a)


the total technical capacity at the virtual interconnection points shall be equal to or higher than the sum of the technical capacities at each of the interconnection points contributing to the virtual interconnection points;










(b)


they facilitate the economic and efficient use of the system including but not limited to rules set out in Article 16 of Regulation (EC) No 715/2009.








Adjacent transmission system operators shall start the necessary analysis and, shall establish functional virtual interconnection points no later than 5 years after the entering into force of this Regulation.


Article 20

Bundling in case of existing transport contracts


1.   The network users who are parties to existing transport contracts at the time of the entry into force of this Regulation at respective interconnection points, should aim to reach an agreement on the bundling of the capacity via contractual arrangements (‘bundling arrangement’), in compliance with the provisions set out in Article 19 of this Regulation. These network users and transmission system operators shall report to the relevant national regulatory authorities of all bundling arrangements reached by all parties to existing transport contracts. On that basis the national regulatory authority shall send a report to the Agency regarding the yearly progress on bundling capacity in the concerned Member State. The Agency shall, two years from the entry into force of this Regulation, publish a report on the progress made on bundling capacity.


2.   The transmission system operators who are parties to the existing transport contracts may participate in the discussions regarding the bundling arrangement at any time, upon invitation of the network users who are parties to the existing transport contracts.


3.   Where a bundling arrangement is agreed upon between respective network users, the transmission system operators involved at the interconnection point shall be informed by the parties of such intended bundling arrangement without undue delay and the transfer of the concerned capacity shall be implemented. In any case, the bundling arrangement shall be implemented subject to the applicable terms and conditions of existing related transport contracts. Once the bundling arrangement is implemented, the relevant capacity shall be treated as bundled capacity.


4.   In any case, the duration of the bundling arrangements regarding the capacity bundled under the amendment of the existing contracts shall not exceed the duration of the original transport contracts.


5.   All capacity shall be bundled at the earliest opportunity. Existing transport contracts for unbundled capacity cannot be renewed, prolonged or rolled over after their expiration date. Such capacity shall become available capacity as of the expiration date of the transport contracts.




CHAPTER V


INTERRUPTIBLE CAPACITY



Article 21

Allocation of interruptible services


1.   Transmission system operators shall offer a daily capacity product for interruptible capacity in both directions at interconnection points where firm capacity has been offered but was sold out day-ahead. At unidirectional interconnection points where technical capacity is offered only in one direction, transmission system operators shall offer a daily product for interruptible capacity in the other direction. Transmission system operators may offer interruptible capacity products of longer duration as well.


2.   If interruptible capacity is offered, this shall not be detrimental to the amount of firm capacity on offer. Transmission system operators shall not set aside capacity that can be offered as firm capacity in order to offer it as interruptible capacity.


3.   To the extent interruptible capacity products other than daily products are offered, the same standard capacity products for firm capacity shall also apply for interruptible capacity, in terms of duration of the products.


4.   To the extent interruptible capacity is offered, it shall be allocated via an auction process with the exception of within-day interruptible capacity.


5.   Within-day interruptible capacity shall be allocated by means of an over-nomination procedure.


6.   Within-day interruptible capacity shall only be allocated when firm capacity, whether technical capacity or additional capacity, is sold out.


7.   Where auctions are held for any interruptible products longer than within-day transmission system operators shall, if known, publish the amounts of interruptible capacity on offer before the start of the auction process.


8.   If offered, interruptible capacity shall be allocated by means of a separate auction after firm capacity of equal duration has been allocated, but before the auction of firm capacity with a shorter duration starts, with the exception of within-day interruptible capacity.


9.   If offered, interruptible capacity auctions shall be conducted in accordance with the same design principles and timescales as applied for firm capacity. The exact timescales applied for the interruptible capacity auctions shall be detailed within the auction calendar with the exception of within-day interruptible capacity.



Article 22

Minimum interruption lead times


1.   Interruptible capacities shall have minimum interruption lead times, which shall be decided jointly by adjacent transmission system operators.


2.   The default minimum interruption lead time for a given gas hour shall be forty five minutes after the start of the re-nomination cycle for that gas hour. Where two transmission system operators wish to shorten the lead time for interruptions, any related agreement entered into between the transmission system operators shall be subject to competent national regulatory authority approval.



Article 23

Coordination of interruption process

The transmission system operator that initiates the interruption shall notify the relevant adjacent transmission system operator. Adjacent transmission system operators shall notify their respective affected network users as soon as possible, but with due regard to the reliability of the information.


Article 24

Defined sequence of interruptions


1.   The order in which interruptions shall be performed, if the total of nominations exceeds the quantity of gas that can flow at a certain interconnection point, shall be determined based on the contractual timestamp of the respective transport contracts on an interruptible basis. In case of an interruption, transport contract coming into force earlier shall prevail over transport contract coming into force later.


2.   If, after applying the procedure described in paragraph 1, two or more nominations are ranked at the same position within the interruption order and the transmission system operator does not interrupt all of them, a pro rata reduction of these specific nominations shall apply.


3.   To accommodate the differences between the various interruptible capacity services within the Union, the adjacent transmission system operators shall implement and coordinate the joint procedures provided for in this Article on an interconnection point by interconnection point basis.



Article 25

Reasons for interruptions

Transmission system operators shall include reasons for interruptions either directly in their interruptible transport contracts or in the general terms and conditions that govern these contracts. Reasons for interruptions can include but are not limited to gas quality, pressure, temperature, flow patterns, use of firm contracts, maintenance, up- or downstream constraints, public service obligations and capacity management deriving from congestion management procedures.



CHAPTER VI


TARIFFS AND CAPACITY BOOKING PLATFORMS



Article 26

Tariffs


1.   The tariff as calculated using the methodology set and/or approved by the national regulatory authority, or the tariff set and/or approved by the national regulatory authority, shall be used as the reserve price in all auctions for all standard capacity products for firm and interruptible capacity.


2.   The payable price determined in a capacity auction can be either a fixed price or a variable price or be subject to other arrangements provided for in the applicable regulatory regime. The fixed price shall consist of the applicable tariff at the time of the auction plus the auction premium. The variable price shall consist of the applicable tariff at the time when the capacity can be used plus the auction premium. The arrangements can be different for the capacities in a bundled product on either side of an interconnection point.


3.   The appropriate tariff arrangements for the implementation of this Regulation shall be set out on a Union and/or national level in due time. These arrangements shall enable the due implementation of the capacity allocation mechanisms established by this Regulation, without incurring detrimental effects on the revenue and cash flow positions of transmission system operators, due to the implementation of this Regulation, in particular the provisions regarding the setting aside of a proportion of capacity, including new capacity, in accordance with Articles 2(3), 8(7), and 8(8) and Article 19(5)(b).


4.   Auction revenues from bundled capacity need to be split between the transmission system operators placing capacities in bundled capacity. The reserve price of the bundled capacity shall be the sum of reserve prices of the capacities in the bundled capacity. All revenues from sales of bundled capacity shall be attributed to the contributing transmission system operators after each capacity transaction.


5.   The revenues from the reserve price of bundled capacity shall be attributed to the transmission system operators in proportion to the reserve prices of their capacities in the bundled capacity. The revenues from the auction premium from bundled capacity above the reserve price shall be split according to agreement between the transmission system operators, approved by the relevant national regulatory authority, where appropriate, in advance of the auctions. Where no agreement is concluded before the auction, the revenues from the auction premium from bundled capacity shall be attributed to the transmission system operators in equal proportions.


6.   National regulatory authorities shall approve over and under recovery mechanisms. Where a price cap regime is applied, the national regulatory authority shall approve the usage of revenues from capacity prices exceeding the respective tariff.



Article 27

Capacity booking platforms


1.   Transmission system operators shall apply this Regulation by offering capacity by means of one or a limited number of joint web-based booking platforms. Transmission system operators can operate such platforms themselves or via an agreed party that, where necessary, acts on behalf of them towards the network users.


2.   Joint booking platforms shall apply the following rules:






(a)


the rules and procedures for the offer and allocation of all capacity in accordance with Chapter III shall apply;










(b)


the establishment of a process to offer firm bundled capacity in accordance with Chapter IV shall have priority;










(c)


functionalities for network users to offer and obtain secondary capacity shall be provided;










(d)


in order to use the services of the booking platforms network users shall accede to and be compliant with all applicable legal and contractual requirements that enable them to book and use capacity on the relevant transmission system operators’ network under a transport contract;










(e)


capacity at any single interconnection point or virtual interconnection point shall be offered at not more than one booking platform.






3.   The establishment of one or a limited number of joint booking platforms shall facilitate and simplify capacity booking at interconnection points across the Union for the benefit of network users. To that end, ENTSOG shall, within six months after the entry into force of this Regulation, carry out a public consultation to identify the market needs. The consultation process shall last no more than six months, including the publication by ENTSOG of a report with the results of the consultation. The report shall identify options to implement the indicated market needs, having regard to costs and time, with a view to implement the most appropriate option, by transmission system operators or third parties on behalf of them. Where appropriate, ENTSOG and the Agency shall facilitate this process.
