            COUNCIL DECISION (EU) 2025/172
         
of 17 December 2024
         
on the position to be taken on behalf of the European Union within the Specialised Committee on Energy established by the Trade and Cooperation Agreement between the European Union and the European Atomic Energy Community, of the one part, and the United Kingdom of Great Britain and Northern Ireland, of the other part, as regards the adoption of a recommendation concerning the preparation of technical procedures for the efficient use of electricity interconnectors


THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty on the Functioning of the European Union, and in particular Article 194(2), in conjunction with Article 218(9), thereof,


Having regard to the proposal from the European Commission,

Whereas:







(1)


On 29 April 2021, the Council adopted Decision (EU) 2021/689 (1) on the conclusion of the Trade and Cooperation Agreement between the European Union and the European Atomic Energy Community, of the one part, and the United Kingdom of Great Britain and Northern Ireland, of the other part (2) (the ‘Trade and Cooperation Agreement’). The Trade and Cooperation Agreement entered into force on 1 May 2021.












(2)


Article 8(1), point (l), of the Trade and Cooperation Agreement established the Specialised Committee on Energy (the ‘Specialised Committee’). The competences of the Specialised Committee are set out in Article 8(4) of that Agreement.












(3)


Pursuant to Article 8(4), point (c), of the Trade and Cooperation Agreement, with respect to issues related to its area of competence the Specialised Committee has the power to adopt decisions and recommendations in respect of all matters where that Agreement or any supplementing agreement so provides or for which the Partnership Council has delegated its powers to it. Pursuant to Article 10(2) of the Trade and Cooperation Agreement, a Committee is to adopt decisions and make recommendations by mutual consent.












(4)


Regarding the electricity trading arrangements between the Union and the United Kingdom, Article 312(1) of the Trade and Cooperation Agreement requires that, for capacity allocation and congestion management at the day ahead stage, the Specialised Committee take, as a matter of priority, the necessary steps in accordance with Article 317 of that Agreement to ensure that transmission system operators (‘TSOs’) for electricity develop arrangements setting out technical procedures in accordance with Annex 29 to that Agreement within a specific timeline.












(5)


In particular, Part 1, point 1, of Annex 29 to the Trade and Cooperation Agreement provides for the development of a new procedure for the allocation of capacity on electricity interconnectors at the day-ahead market timeframe. The new procedure is to be based on the concept of ‘multi-region loose volume coupling’.












(6)


On 10 July 2023, the TSOs of the Union and of the United Kingdom delivered a report, following Recommendation No 1/2023 of the Specialised Committee of 7 February 2023 (3), requesting that the TSOs address a number of questions as regards the implementation of the multi-region loose volume coupling. That report was supplemented by an informal opinion of the European Union Agency for the Cooperation of Energy Regulators (ACER) and of the United Kingdom regulatory authorities.












(7)


Considering the conclusions of the TSO report of 10 July 2023, supported by the informal opinion of ACER and of the United Kingdom regulatory authorities, it is appropriate for the Specialised Committee to recommend further action to the Parties.












(8)


The Specialised Committee is to adopt a recommendation on further action to be taken either at a forthcoming meeting or by written procedure, following the completion of domestic procedures by each Party.












(9)


It is appropriate to establish the position to be taken on the Union's behalf within the Specialised Committee, as the recommendation of the Specialised Committee will be capable of decisively influencing the content of or the way in which the Union acquis is to be implemented, in particular Commission Regulation (EU) 2015/1222 (4),





HAS ADOPTED THIS DECISION:



Article 1
The position to be taken on the Union’s behalf within the Specialised Committee on Energy established by Article 8(1), point (l), of the Trade and Cooperation Agreement between the European Union and the European Atomic Energy Community, of the one part, and the United Kingdom of Great Britain and Northern Ireland, of the other part, is set out in the draft recommendation of that Committee attached to this Decision.


Article 2
This Decision shall enter into force on the date of its adoption.

ANNEX



RECOMMENDATION No …/2024 OF THE SPECIALISED COMMITTEE ON ENERGY ESTABLISHED BY ARTICLE 8(1), POINT (l), OF THE TRADE AND COOPERATION AGREEMENT BETWEEN THE EUROPEAN UNION AND THE EUROPEAN ATOMIC ENERGY COMMUNITY, OF THE ONE PART, AND THE UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND, OF THE OTHER PART
of …
to each Party concerning the preparation of technical procedures for the efficient use of electricity interconnectors


THE SPECIALISED COMMITTEE ON ENERGY,

Having regard to the Trade and Cooperation Agreement between the European Union and the European Atomic Energy Community, of the one part, and the United Kingdom of Great Britain and Northern Ireland of the other part (1) (the ‘Trade and Cooperation Agreement’), and in particular Article 311(1) and (2), Article 312(1) and (2), Article 317(1), (2) and (3), and Annex 29 thereof,

Whereas:







(1)


Pursuant to Article 8(4), point (a), of the Trade and Cooperation Agreement, the Specialised Committee on Energy (the ‘Specialised Committee’) has the power to monitor and review the implementation and ensure the proper functioning of the Trade and Cooperation Agreement in its area of competence. Pursuant to Article 8(4), point (c), it has the power to adopt decisions and recommendations in respect of all matters where the Trade and Cooperation Agreement so provides or for which the Partnership Council has delegated its powers to the Specialised Committee pursuant to Article 7(4), point (f). Pursuant to Article 329(3) of the Trade and Cooperation Agreement, it shall make recommendations as necessary to ensure the effective implementation of the Chapters of Title VIII for which it is responsible.












(2)


Pursuant to Article 312(1) of the Trade and Cooperation Agreement, the Specialised Committee, as a matter of priority, shall take the necessary steps in accordance with Article 317 to ensure that transmission system operators (‘TSOs’) develop arrangements setting out technical procedures in accordance with Annex 29 within a specific timeline.












(3)


On 7 February 2023, the Specialised Committee adopted Recommendation No 1/2023 (2) for each Party to request its respective TSOs to provide the additional information as set out in Annex II to that Recommendation within five months of the date of request made by each Party.












(4)


The European Union (EU) and United Kingdom (UK) TSOs provided that additional information to the Parties in response to their respective requests. In July 2023, the regulatory authorities of the EU and the UK, respectively, provided opinions to the Parties on that additional information. The Specialised Committee welcomed these important contributions to the implementation of Title VIII of the Trade and Cooperation Agreement at the Specialised Committee meeting on 9 November 2023.












(5)


Both the EU and the UK TSOs and regulatory authorities have identified significant risks of market manipulation associated with the Preliminary Order Books approach to the operation of day-ahead electricity trading arrangements based on the concept of Multi-region loose volume coupling (‘MRLVC’).












(6)


Both the EU and the UK TSOs and regulatory authorities have identified that the potential benefits of the Common Order Book approach to MRLVC will depend on the resolution of a number of fundamental design challenges. Further specific work to develop a robust design for MRLVC following a Common Order Book approach is needed before any decision on implementation can be made. That design will, among other requirements, need to ensure the secure and efficient operation of the respective EU and UK electricity wholesale markets, and address any trade-off between the efficiency of MRLVC and the secure and efficient operation of the EU and UK electricity wholesale markets. Thorough consultation, assessment and testing of the mechanism will also be required ahead of any decision on implementation. Moreover, the Specialised Committee noted that development of the design must be consistent with the process set out in Articles 312(1), 312(2) and 317 of the Trade and Cooperation Agreement and requirements set out in Annex 29.












(7)


Both the 2021 cost-benefit analysis (the ‘2021 CBA’) and the 2023 additional information prepared by EU and UK TSOs have found that the efficiency of MRLVC will depend to a significant extent on the accuracy of the bordering bidding zone net position forecaster. Further specific work to develop and confirm the validity of the concept of that forecaster is needed before a decision on implementation can be made. The Specialised Committee noted that EU and UK TSOs proposed a phased approach to the development of the forecaster in their report, beginning with an initial prototype design and validation phase.












(8)


Both the EU and the UK have ambitious goals to unleash the offshore renewable energy potential in the North Seas to enhance access to affordable energy and advance their transitions towards climate neutrality. Pursuant to Article 321 of the Trade and Cooperation Agreement, the Parties shall cooperate in the development of offshore renewable energy by sharing best practices and, where appropriate, by facilitating the development of specific projects. In their report, the EU and UK TSOs identified that the future development of offshore hybrid projects will require electricity trading arrangements that support efficient pricing and capacity utilisation. The Specialised Committee acknowledged that further consideration needed to be given to ensuring that EU-UK electricity trading arrangements support their ambitions for the rapid development of renewable energy projects in the North Seas.












(9)


The 2021 CBA identified a single Great Britain clearing price at the day-ahead timeframe as an assumption in all MRLVC design options under consideration. The UK published its consultation response on re-coupling relevant Great Britain auctions for cross-border trade with the EU at the day-ahead timeframe in August 2023. The UK’s analysis showed that the majority of respondents were supportive of the proposals set out in the consultation. The UK has since engaged with the Specialised Committee and presented the outcomes of the consultation.












(10)


In the light of progress achieved to date by the TSOs and the additional information provided in response to Annex II to Recommendation No 1/2023, the Specialised Committee should address the Parties to ensure that the TSOs commence a next phase of work. That work should focus on addressing the fundamental design issues which have been previously highlighted to satisfy the Specialised Committee’s obligations under Article 312(1) of the Trade and Cooperation Agreement.












(11)


The Specialised Committee noted that the Parties expect a phased approach to the development of technical procedures for MRLVC, starting with an initial concept-validation phase. In light of findings from the TSO report submitted in July 2023, further analysis is necessary and should be included in the concept validation phase. The initial concept-validation phase should inform and support the development of a single set of draft technical procedures for MRLVC in line with Articles 312(1) and 317(2) of the Trade and Cooperation Agreement.












(12)


Any decision by the Specialised Committee on the implementation of technical procedures for an MRLVC solution following a Common Order Book approach, pursuant to Article 317(4) of the Trade and Cooperation Agreement, should be supported by stakeholder consultation, robust periods of testing and an updated cost benefit analysis,





HAS ADOPTED THIS RECOMMENDATION,



Article 1
The Specialised Committee acknowledges that the Preliminary Order Books approach is not a viable way forward for the further development of a Multi-region loose volume coupling (‘MRLVC’) solution and recommends that the Parties not pursue it further.


Article 2
The Specialised Committee recommends that each Party request that its respective TSOs for electricity and, for the Union, the European Network of Transmission System Operators for Electricity (‘ENTSO-E’) facilitating the work of EU TSOs jointly commence an initial concept-validation phase prior to producing the single set of initial draft technical procedures for MRLVC in accordance with Annex 29 to the Trade and Cooperation Agreement and with supporting analysis, comprising:






(a)


an optimal operational timeline combining the operations of the MRLVC, the EU Single Day-Ahead Coupling and the Great Britain wholesale electricity market arrangements under a Common Order Book approach, including the optimal validation and fallback arrangements. The optimal operational timeline should promote the robust and efficient use of interconnectors while minimising risks for the secure operation of the EU and UK electricity wholesale markets and taking into account possible market developments up to 2030-35. The operational risks linked to that timeline on both the EU Single Day-Ahead Coupling and the Great Britain wholesale electricity market should be assessed and, to the extent possible, quantified. A range of options for operational timelines should be included in the supporting analysis to support the identification and assessment of the validity of an optimal timeline;










(b)


a draft tender specification for a prototype for a bordering bidding zone net position forecaster which should:






(i)


include a detailed description of requirements, including:






—


the methodology (e.g., statistical and/or deterministic) to be employed;










—


specific outputs that would be required from the forecaster;










—


how the forecaster will incorporate future market developments, including the future introduction of new bidding zones whether onshore or offshore;










—


how outputs from the forecaster will be inputted into wider MRLVC processes;










—


any other key requirements identified through the work set out under point (a) of this Article and Article 3;














(ii)


be accompanied by:






—


information on how the tender would be issued and governed, including consideration of ownership and intellectual property rights;










—


a detailed breakdown of anticipated timings and costs;










—


any relevant issue related to administrative functions required to address EU and UK system interdependencies in the implementation of an MRLVC solution.














Article 3

1.   The Specialised Committee recommends that the Parties request that their respective TSOs for electricity and, for the Union, the ENTSO-E facilitating the work of EU TSOs produce a joint report for the Specialised Committee investigating any barriers to the delivery of joint and hybrid offshore projects that may result from existing trading arrangements or MRLVC, and any specific changes needed to existing trading arrangements or specific requirements of the design of MRLVC needed to deliver efficient electricity trading that supports the delivery of joint and hybrid offshore projects.


2.   The TSOs joint report should:






(a)


investigate the impact of both existing trading arrangements and an MRLVC solution on joint and hybrid projects, over the medium term (2030-2035 horizon), with a particular focus on:






(i)


the scope of the application of the trading arrangements, and whether and how the performance of capacity allocation may be affected;










(ii)


how these trading arrangements could operate with different market designs, in particular offshore bidding zones; and










(iii)


whether there may be sufficient clarity in the business case for infrastructure investment;














(b)


take into consideration:






(i)


the nature and scale of possible offshore renewable energy infrastructure developments across the North Seas in the medium term, including possible hybrid interconnectors, energy islands, meshed grids and offshore electrolysers;










(ii)


possible mechanisms of price formation;










(iii)


the complementary role of forward and intraday trading arrangements;










(iv)


the impact on the accuracy of bordering bidding zone forecasts; and










(v)


any specific adjustments that may be required in the design features of these trading arrangements, within their general confines, to help address any identified barriers and/or requirements in the development and operation of joint and hybrid offshore projects to deliver efficient trading arrangements.











Article 4
The development of the work recommended under Articles 2 and 3 should involve regular oversight and input by the Parties. It may also involve the TSOs engaging with wider stakeholders that may include regulators, nominated electricity market operators/power exchanges, and academia.


Article 5
The Specialised Committee recommends that the Parties coordinate their communication with their respective TSOs for electricity and, for the Union, the ENTSO-E facilitating the work of EU TSOs with respect to Articles 2 and 3 and request that they complete the work listed under those Articles within 11 months of the adoption of this Recommendation.


Article 6
The Specialised Committee recommends that the Parties request that their respective TSOs for electricity and, for the Union, the ENTSO-E facilitating the work of EU TSOs request an informal opinion of the UK national energy regulators and ACER regarding their work completed with respect to Articles 2 and 3, to be delivered within one month of the delivery of the TSOs joint report.
