COMMISSION REGULATION (EU) 2017/460

of 16 March 2017

establishing a network code on harmonised transmission tariff structures for gas

(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 the European Parliament and of the Council of 13 July 2009 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)

In line with Regulation (EC) No 715/2009, it is necessary to establish a network code on harmonised transmission tariff structures for gas, and set out the Union-wide rules which have the objectives of contributing to market integration, enhancing security of supply and promoting the interconnection between gas networks.

(2)

A crucial step in reaching these objectives is to increase the transparency of transmission tariff structures and procedures towards setting them. Therefore, it is necessary to set out the requirements for publishing the information related to the determination of the revenues of transmission system operators and to the derivation of different transmission and non-transmission tariffs. These requirements should enable network users to understand better the tariffs set for both transmission services and non-transmission services, as well as how such tariffs have changed, are set and may change. Additionally, network users should be able to understand the costs underlying transmission tariffs and to forecast transmission tariffs to a reasonable extent. The transparency requirements set out in this Regulation further harmonise the rule laid down in point 3.1.2(a) of Annex I to Regulation (EC) No 715/2009.

(3)

After the introduction of the concept of the entry-exit system by Regulation (EC) No 715/2009, transmission costs are no longer directly associated to one specific route as entry and exit capacity can be contracted separately, and network users can have gas transported from any entry to any exit point. Under this framework, the transmission system operator decides the most efficient way of flowing gas through the system. Hence, in order to achieve and ensure a reasonable level of cost reflectivity and predictability in such a system, transmission tariffs need to be based on a reference price methodology using specific cost drivers. The guiding principles in order to apply a consistent and transparent reference price methodology should be set out. The obligation to consult on the proposed reference price methodology should be laid down. Where the proposed reference price methodology is other than the capacity weighted distance reference price methodology, the latter should serve as a counterfactual for comparison with the proposed reference price methodology.

(4)

In order to avoid double charging for transmission to and from storage facilities, this Regulation should set a minimum discount acknowledging the general contribution to system flexibility and security of supply of such infrastructure. Storage facilities with direct access to the transmission systems of two or more transmission system operators in directly connected entry-exit systems, or simultaneously to a transmission system and a distribution system allow for transporting gas between directly connected systems. Applying a discount at entry points from or exit points to storage facilities in cases where storage facilities are used to transport gas between directly connected systems would benefit these network users compared to other network users booking capacity products without a discount at interconnection points or using storage facilities to transport gas within the same system. This Regulation should introduce mechanisms to avoid such discrimination.

(5)

In order to promote security of supply, the granting of discounts should be considered for entry points from LNG facilities, and at entry points from and exit points to infrastructure developed with the purpose of ending the isolation of Member States in respect of their gas transmission systems.

(6)

Transmission system operators in certain entry-exit systems transport significantly more gas into other systems than for consumption into their own entry-exit system. Consequently, reference price methodologies should include safeguards required to shelter such captive customers from risks related to large transit flows.

(7)

In order to promote stability of transmission tariffs for network users, to foster financial stability and to avoid detrimental effects on the revenue and cash flow positions of transmission system operators, principles for revenue reconciliation should be set out.

(8)

In addition, rules should be set out on tariff principles for incremental capacity realised in a market-based manner according to the process set out in Articles 26 to 30 of Commission Regulation (EU) 2017/459 (2). In case realisation of incremental capacity leads to a level of cross-subsidisation that cannot be justified, as captive costumers would be exposed to a large share of the volume risk, this Regulation should introduce mechanisms to alleviate such risks.

(9)

This Regulation should be applicable to the non-exempted part of major new infrastructures which have received an exemption pursuant to Article 36 of Directive 2009/73/EC of the European Parliament and of the Council (3) from Article 41(6), (8) and (10) of that Directive. In cases where the specific nature of interconnectors has been acknowledged at European level by an exemption in accordance with Article 36 of Directive 2009/73/EC or by other means, national regulatory authorities should have the power to grant a derogation from requirements of this Regulation which would jeopardise the efficient operation of such interconnectors.

(10)

This Regulation should be without prejudice to application of Union 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 harmonised transmission tariff structures put in place should be designed in such a way as to avoid foreclosure of downstream supply markets.

(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 for the Cooperation of Energy Regulators and the national regulatory authorities should ensure that rules on harmonised transmission tariff structures for gas are implemented across the Union in the most effective way.

(12)

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

HAS ADOPTED THIS REGULATION:

Article 10

Rules for entry-exit systems within a Member State where more than one transmission system operator is active

1.   In accordance with Article 6(3), the same reference price methodology shall be applied jointly by all transmission system operators within an entry-exit system within a Member State.

2.   As an exception to paragraph 1 and subject to paragraph 3, the national regulatory authority may decide:

(a)

that the same reference price methodology is applied separately by each transmission system operator within an entry-exit system;

(b)

as an exception to Article 6(3), when planning entry-exit system mergers, on intermediate steps allowing for different reference price methodologies to be applied separately by each transmission system operator within the entry-exit systems concerned. Such a decision shall set out the time period for the application of the intermediate steps. The national regulatory authority or the transmission system operators, as decided by the national regulatory authority, shall carry out an impact assessment and a cost benefit analysis prior to implementing such intermediate steps.

As a result of applying different reference price methodologies separately, the transmission services revenue of the transmission system operators involved shall be adjusted accordingly.

3.   In order to allow for the proper application of the same reference price methodology jointly, an effective inter-transmission system operator compensation mechanism shall be established.

The decision referred to in paragraph 2(a) or, respectively, paragraph 2(b) may be taken where the following conditions are complied with:

(a)

an effective inter-transmission system operator compensation mechanism is established with the aim to:

(i)

prevent detrimental effects on the transmission services revenue of the transmission system operators involved;

(ii)

avoid cross-subsidisation between intra-system and cross-system network use;

(b)

such separate application ensures that the costs correspond to those of an efficient transmission system operator.

4.   The maximum time period set out in the decision referred to in paragraph 2(a) or, respectively, paragraph 2(b) shall be no later than five years as from the date referred to in Article 38(2). Sufficiently in advance of the date set out in that decision, the national regulatory authority may decide to postpone this date.

RESERVE PRICES

Article 12

General provisions

1.   For yearly standard capacity products for firm capacity, the reference prices shall be used as reserve prices. For non-yearly standard capacity products for firm capacity, the reserve prices shall be calculated as set out in this Chapter. For both yearly and non-yearly standard capacity products for interruptible capacity, the reserve prices shall be calculated as set out in this Chapter. The level of multipliers and of seasonal factors, set out in accordance with Article 13, and the level of discounts for the standard capacity products for interruptible capacity, set out in accordance with Article 16, may be different at interconnection points.

2.   Where the tariff period and gas year do not coincide, separate reserve prices may be applied respectively:

(a)

for the time period from 1 October to the end of the prevailing tariff period; and

(b)

for the time period from the beginning of the tariff period following the prevailing tariff period to 30 September.

3.   The respective reserve prices published according to Article 29 shall be binding for the subsequent gas year or beyond the subsequent gas year in case of fixed payable price, beginning after the annual yearly capacity auction, unless:

(a)

the discounts for monthly and daily standard capacity products for interruptible capacity are recalculated within the tariff period if the probability of interruption referred to in Article 16 changes by more than twenty percent;

(b)

the reference price is recalculated within the tariff period due to exceptional circumstances under which the non-adjustment of tariff levels would jeopardise the operation of the transmission system operator.

Article 13

Calculation of reserve prices for non-yearly standard capacity products for firm capacity with seasonal factors

1.   Where seasonal factors are applied, the reserve prices for non-yearly standard capacity products for firm capacity shall be calculated in accordance with the relevant formulas set out in Article 14 which shall be then multiplied by the respective seasonal factor calculated as set out in paragraphs 2 to 6.

2.   The methodology set out in paragraph 3 shall be based on the forecasted flows, unless the quantity of the gas flow at least for one month is equal to 0. In such case, the methodology shall be based on the forecasted contracted capacity.

3.   For monthly standard capacity products for firm capacity, the seasonal factors shall be calculated in the following sequential steps:

(a)

for each month within a given gas year the usage of the transmission system shall be calculated on the basis of forecasted flows or forecasted contracted capacity using:

(i)

the data for the individual interconnection point, where the seasonal factors are calculated for each interconnection point;

(ii)

the average data on the forecasted flows or the forecasted contracted capacity, where the seasonal factors are calculated for some or all of the interconnection points.

(b)

the resulting values referred to in point (a) shall be summed up;

(c)

the usage rate shall be calculated by dividing each of the resulting values referred to in point (a) by the resulting value referred to in point (b);

(d)

each of the resulting values referred to in point (c) shall be multiplied by 12. Where the resulting values are equal to 0, these values shall be adjusted to whichever of the following is the lower: 0,1 or the lowest of the resulting values other than 0;

(e)

the initial level of the respective seasonal factors shall be calculated by raising each of the resulting values referred to in point (d) to the same power which is no less than 0 and no more than 2;

(f)

(g)

the resulting value referred to in point (f) shall be compared with the range referred to in Article 13(1), as follows:

(i)

if this value falls within this range then the level of seasonal factors shall be equal to with the respective resulting values referred to in point (e);

(ii)

if this value falls outside of this range then point (h) shall apply.

(h)

the level of seasonal factors shall be calculated as the product of the respective resulting values referred to in point (e) and the correction factor calculated as follows:

(i)

where the resulting value referred to in point (f) is more than 1,5, the correction factor shall be calculated as 1,5 divided by this value;

(ii)

where the resulting value referred to in point (f) is less than 1, the correction factor shall be calculated as 1 divided by this value.

4.   For daily standard capacity products for firm capacity and within-day standard capacity products for firm capacity, the seasonal factors shall be calculated by carrying out the steps set out in paragraph 3(f) to (h), mutatis mutandis.

5.   For quarterly standard capacity products for firm capacity, the seasonal factors shall be calculated in sequential steps as follows:

1.   The reserve prices for standard capacity products for interruptible capacity shall be calculated by multiplying the reserve prices for the respective standard capacity products for firm capacity calculated as set out in Articles 14 or 15, as relevant, by the difference between 100 % and the level of an ex-ante discount calculated as set out in paragraphs 2 and 3.

2.   An ex-ante discount shall be calculated in accordance with the following formula:

 

Diex-ante = Pro × A × 100 %

Where:

 

Diex-ante is the level of an ex-ante discount;

 

Pro factor is the probability of interruption which is set or approved in accordance with Article 41(6)(a) of Directive 2009/73/EC pursuant to Article 28, and which refers to the type of standard capacity product for interruptible capacity;

 

A is the adjustment factor which is set or approved in accordance with Article 41(6)(a) of Directive 2009/73/EC pursuant to Article 28, applied to reflect the estimated economic value of the type of standard capacity product for interruptible capacity, calculated for each, some or all interconnection points, which shall be no less than 1.

3.   The Pro factor referred to in paragraph 2 shall be calculated for each, some or all interconnection points per type of standard capacity product for interruptible capacity offered in accordance with the following formula on the basis of forecasted information related to the components of this formula:

 

Formula

Where:

 

N is the expectation of the number of interruptions over D;

 

Dint is the average duration of the expected interruptions expressed in hours;

 

D is the total duration of the respective type of standard capacity product for interruptible capacity expressed in hours;

 

CAPav. int is the expected average amount of interrupted capacity for each interruption where such amount is related to the respective type of standard capacity product for interruptible capacity;

 

CAP is the total amount of interruptible capacity for the respective type of standard capacity product for interruptible capacity.

4.   As an alternative to applying ex-ante discounts in accordance with paragraph 1, the national regulatory authority may decide to apply an ex-post discount, whereby network users are compensated after the actual interruptions incurred. Such ex-post discount may only be used at interconnection points where there was no interruption of capacity due to physical congestion in the preceding gas year.

The ex-post compensation paid for each day on which an interruption occurred shall be equal to three times the reserve price for daily standard capacity products for firm capacity.

CHAPTER IX

INCREMENTAL CAPACITY

Article 33

Tariff principles for incremental capacity

1.   The minimum price at which transmission system operators shall accept a request for incremental capacity is the reference price. For the calculation of the economic test, reference prices shall be derived by including into the reference price methodology the relevant assumptions related to the offer of incremental capacity.

2.   Where the fixed payable price approach set out in Article 24(b) is considered to be offered for incremental capacity, the reserve price referred to in Article 24(b) shall be based on projected investment and operating costs. Once the incremental capacity is commissioned, such reserve price shall be adjusted proportionally to the difference, irrespective whether positive or negative, between the projected investment costs and the actual investment costs.

3.   In case the allocation of all incremental capacity at the reference price would not generate sufficient revenues for a positive economic test outcome, a mandatory minimum premium may be applied in the first auction or alternative allocation mechanism in which the incremental capacity is offered. The mandatory minimum premium may also be applied in subsequent auctions when the capacity is offered that initially remained unsold or when capacity is offered that was initially set aside according to Article 8(8) and (9) of Regulation (EU) 2017/459. The decision on whether and in which auctions to apply a mandatory minimum premium shall be taken in accordance with Article 41(6)(a) of Directive 2009/73/EC.

4.   The level of the mandatory minimum premium shall enable a positive economic test outcome with the revenues generated by the offered capacity in the first auction or alternative allocation mechanism in which the incremental capacity is on offer. The range of the level for the mandatory minimum premium, depending on the expected allocated capacity, shall be submitted to the relevant national regulatory authorities for approval in accordance with Article 25(1)(c) of Regulation (EU) 2017/459.

5.   A mandatory minimum premium approved by the national regulatory authority shall be added to the reference price for the bundled capacity products at the respective interconnection point and shall exclusively be attributed to the transmission system operators for which the mandatory minimum premium was approved by the respective national regulatory authority. This default principle for the attribution of a mandatory minimum premium is without prejudice to the split of a possible additional auction premium according to Article 21(3) or an alternative agreement between the involved national regulatory authorities.

1.   National regulatory authorities may, at the request of an entity which operates an interconnector that has benefited from an exemption from Article 41(6), (8) and (10) of Directive 2009/73/EC in accordance with Article 36 of that Directive or a similar exemption, jointly grant such entity a derogation from the application of one or more Articles of this Regulation in accordance with paragraphs 2 to 6 of this Article where the application of those Articles to such entity would have one or several of the following negative consequences. It would:

(a)

not facilitate efficient gas trade and competition;

(b)

not provide incentives for investment for new capacity or to maintain existing levels of capacity;

(c)

unreasonably distort cross-border trade;

(d)

distort competition with other infrastructure operators that offer services of a similar nature to those of the interconnector;

(e)

not be implementable when taking into account the specific nature of interconnectors.

2.   The entity requesting a derogation under paragraph 1 shall include in its request a detailed reasoning, with all supporting documents, including, where appropriate, a cost-benefit analysis, demonstrating that one or more of the conditions in paragraph 1(a) to (e) are complied with.

3.   The national regulatory authorities concerned shall jointly assess the request for a derogation and deal with it in close cooperation. Where the relevant national regulatory authorities grant a derogation, they shall specify its duration in their decisions.

4.   The national regulatory authorities shall notify their decisions granting such derogations to the Agency and the Commission.

5.   The national regulatory authorities may revoke a derogation if the circumstances or underlying reasons, or both, no longer apply or upon a reasoned recommendation of the Agency or the Commission to revoke a derogation due to a lack of justification.
