text: Opinion No 08/2021

text: ACER recalls its view from the past opinion that the absence of full monetisation of the expected benefits of projects renders the CBA not fit for the purpose of correctly comparing all the costs and all the expected benefits associated with the projects’ planned implementation. 5 ACER recalls its view from the past opinion that the quality of ENTSOG’s TYNDP should be improved, and in particular the results of the application of the PS-CBA, so that the TYNDP would produce an output for each project which unambiguously demonstrates whether a project’s benefits exceed its costs in monetary terms, and indicate the economic value of all the net benefits individually for all proposed projects on a comparable basis.

text: Opinion No 08/2021

text: nd (28) ACER recalls its view that the 2 CBA methodology should be of such nature and implementation modality as to allow all stakeholders independently to replicate the CBA results. ACER proposes that the PCI assessment methodology contains clear procedures and techniques allowing Regional Groups members independently to replicate the technical results, should they wish to do so.

text: ENTSOG uses different infrastructure configurations (called “levels”) when considering the available infrastructure on the basis of which the PCI candidates are assessed at system-wide level in order to identify how they mitigate the investment gaps: 1. The ”low infrastructure level” considers only the existing infrastructure and FID projects; it is the reference point for the identification of infrastructure needs. 2. The “advanced infrastructure level” considers the existing infrastructure, FID projects, and “advanced” projects. This level represents a certain configuration of the infrastructure with reasonable confidence, therefore providing a meaningful basis for the energy system-wide assessment of the concerned projects.

text: The results in this section cover candidate projects that were grouped and communicated to the Regional Groups in the beginning of the process, thus including a broader scope of projects than those on the draft regional PCI lists. 14 ACER shared the detailed NRAs assessment table with the European Commission. These criteria scrutinise whether the candidate project involves at least two Member States by directly crossing the border between them, or it is located in one Member State but has a significant cross-border impact, or it crosses the border of an EU Member State and a country of the European Economic Area. 16 These are: security of supply, market integration, competition and sustainability. 17 Including net present value, the benefit-to-cost ratio and the sensitivity of the cost figures, where applicable, due to non-availability of the Economic Performance Indicator data for NRAs, unless direct requests for such data were made by the NRAs to project promoters.

text: 1. INTRODUCTION

text: (1) According to

text: Article 3 of Regulation (EU) No 347/2013

text: , a Union list of Projects of Common Interest (‘PCIs’) shall be established every two years, on the basis of the regional lists adopted by the decision-making bodies of the Regional Groups as set out in Annex III.1 to the same Regulation. (2) The draft regional lists of proposed projects falling under the categories set out in Annex II.1 and 2 to

text: 2. ASSESSMENT OF THE DRAFT GAS PCI LISTS

text: Assessment of the process and the methodology used for drafting the draft Regional PCI lists

text: 2.1.1. The organisation of the PCI selection process

text: (10) The process followed during the 2021 selection round is similar to the one of the 2019 selection round. ACER welcomes the following positive aspects of the fifth PCI selection process:

text:  The involvement of various stakeholders, including non-governmental organisations, in the Regional Group meetings. The presentations on individual project proposals in these Regional Groups enabled all stakeholders to get up-todate information about essential project features of all candidate projects.

text:  The allotment of sufficient time (from 22 January 2021 to 19 March 2021) for NRAs’ consultations and assessments of the PCI candidates. In this round, the results of project-specific cost-benefit analyses (CBAs) were made available at the start of the consultation process. Nevertheless, similarly to the past selection processes, the CBA results did not contain all the information (Economic Performance Indicators) which NRAs need for a thorough assessment of the projects. NRAs had access to such information only if they individually requested and received the Economic Performance Indicators directly from project promoters.

text:  The development of the methodology for providing a sustainability indicator, taking into account the impact on CO2 emissions and other externalities (such as PMx, NOx and SOx), started well in advance of the PCI selection process. The participants of the Cooperation Platform were informed on the principles of the sustainability indicator development.

text: (11) ACER commends the discussions with the European Commission and the European Network of Transmission System Operators for Gas (ENTSOG) held in the framework of the Cooperation Platform . The European Commission led and chaired the proceedings of the PCI Cooperation Platform, and facilitated the ongoing activities during the PCI selection process.

text: (12) At the same time, ACER notes limited effects of specific discussions within the Cooperation Platform (CP), especially regarding further improvement of the quality and transparency of the selection process. In particular, ACER regrets not being able to discuss the final proposal of the methodology for the assessment of the candidate

text: projects in advance of the last RG meetings (21-22 July 2021), where the project ranking was presented by the European Commission.

text: (13) ACER would favour more clarity on how the decision was made for the approach taken with respect to the selected weights of the indicators, as well as on the more detailed methodology for costs scoring allocation and the predefined benefit - cost threshold value for inclusion in the draft regional PCI lists. ACER is of the opinion that the selected weights among the four specific criteria, set by

text: Article 4(2)

text: (b) of

text: Regulation (EU) No 347/2013

text: , should have been the result of a studied approach and a substantiated dialogue among the Regional Group members.

text: (14) ACER recommends for the next selection round that the European Commission provides intermediate results of the final scoring to the participants of the Cooperation Platform in advance of the last Regional Group meeting. This would allow ACER and ENTSOG to gain better insight and provide informed comments on the application of the methodology before the ranking is presented to the RGs.

text: (15) Even though the European Commission’s requests to ACER and ENTSOG for inputs to the Cooperation Platform were made well in advance of the meetings, the level of acceptance of suggestions and requests made by ACER and NRAs was below their expectations, in particular in the area of a transparent application of the methodology for the assessment of the candidate projects.

text: (16) In order to further improve the efficiency and transparency of future PCI selection processes, ACER recommends that:

text:  The information available in ACER’s most recent PCI monitoring report be taken into account, by also making evident if and how the information from the report has been considered when deciding on the inclusion or exclusion of projects in the final PCI lists.  Greater transparency should be provided on the PCI assessment process, especially when various stakeholders request the disclosure of more details of the final ranking. ACER notes that the results of the calculations used for project ranking were presented at the Regional Group meetings held on 21-22 June 2021. However, the results presented at these meetings only covered those projects which were selected for inclusion in the draft regional lists, meaning that calculations were not made available to all Regional Groups’ members for all projects proposed by the Regional Groups .  Due to complexity of the PCI assessment methodology combined with a simplified description, ACER finds it difficult to reproduce the calculations and verify the

text: results. ACER recommends that the methodology should rather be renamed “Principles of PCI selection and ranking”, which avoid giving an impression of a detailed methodology that would be easily applicable.

text:  The proposed draft regional PCI lists should provide more details on how the assessment was carried out and the justification for the inclusion or exclusion of certain candidate projects from the draft lists be provided to all members of the Regional Groups.

text: (17) ACER notes that the final TYNDP 2020 was finalised only in July 2021, which firstly means that TYNDP was late and secondly, it was deemed inadequate by ACER. ACER recommends that Commission clarifies how both the late submission and its inadequacy affected the PCI selection process.

text: 2.1.2. Identification of infrastructure needs and related preparatory activities

text: (18) ACER finds that the methodology used for the identification and assessment of infrastructure issues and needs helps to ascertain whether a candidate project addresses an infrastructure gap, or whether it may lead to redundant capacities in the existing gas transmission system. ACER positively notes that the PCI selection process included a comparative assessment of the way in which candidate projects address system development needs.

text: (19) ACER welcomes the simplification of the methodology used for the identification of infrastructure needs, notably the reduction and the simplification of indicators.

text: (20) As in previous selection processes, ACER commends the high level of consistency between the outputs of the methodology for the identification of infrastructure needs and the methodology for assessing the candidate PCI projects, achieved by the use of the same indicators.

text: (21) ACER appreciates the important improvement of the process by the inclusion of the sustainability assessment. In particular, the sustainability need was recognised in each Member State, and projects had to show their contribution to address it.

text: (22) ACER calls for greater transparency of the results stemming from the application of the methodology for the identification of infrastructure needs, which has been presented during RG meetings. ACER is of the opinion that the results should be available to all members of the RGs, rather than being only available and discussed bilaterally with a requesting Member State.

text: 2.1.3. The selection methodology for candidate projects

text: (23) ACER appreciates the Commission’s study performed for the purpose of measuring the contribution of gas infrastructure projects to sustainability. The study has been conducted well in advance of the PCI selection process, also involving ENTSOG. A

text: comparison between the newly developed “sustainability methodology” and the one used in the 2019 PCI selection process could show the improvements which the updated methodology brought; however, unfortunately no such comparison has been presented during the process. Such a comparison could highlight the improved assessments of the projects’ contributions to sustainability and provide better insights into the way in which each project helps to resolve the need for sustainability.

text: (24) In this context, ACER commends ENTSOG for introducing a flow-based allocation of sustainability benefits to candidate projects. In particular, ACER positively notes that the ability of existing infrastructure to flow gases is considered first, and only then the potential benefits resulting from incremental flows attributable to candidate projects are considered.

text: (25) In order to properly measure the contribution of gas infrastructure projects to sustainability and take this into account, ACER recommends for the next selection process to address also the methane emissions as a part of the sustainability indicator. An evaluation of projects’ methane emissions from project-level and system-wide emissions perspective would then give a more complete picture on the assessed projects’ impact on GHG emissions.

text: (26) ACER notes that the benefits of projects have been considered only when addressing the system needs identified per MS, and not beyond the identified system need’s threshold. ACER acknowledges that such a way of considering projects’ benefits ensures that only the most relevant projects addressing system needs are considered for the PCI list. ACER also welcomes the approach whereby more benefits are allocated to projects that positively contribute to improvements in MSs which are in a worse initial position from a system situation perspective, i.e. in MSs which are lagging behind the predefined threshold.

text: (27) Comparing to the previous PCI selection process, ACER sees no improvement in the PCI assessment methodology used for the scoring and ranking of the candidate projects. The PCI assessment methodology only foresees the use of non-monetised benefits, i.e. the methodology relies entirely on non-monetised multi-criteria analyses nd and assessments, and completely bypasses the capabilities of the existing 2 CBA Methodology to monetise benefits , as well as any already available information about monetised benefits. Even when taking into consideration the serious limitations of the nd 5 2 CBA Methodology for monetising benefits, the reliance solely on non-monetised indicators obscures a fundamental feature of the proposed projects, namely the

text: balance of costs and monetised benefits which projects are expected to bring. Furthermore, ACER regrets that the Economic Performance Indicators of the projects were not available to the Regional Groups, but only at a specific request of an NRA to the respective project promoter.

text: (29) Furthermore, ACER recalls its recommendation that the European Commission foresees the relevant data collection and provision tools, which should enable all stakeholders, including NRAs, TSOs, and ENTSOG, to assess the impact of energy supply-side and demand-side scenarios on various proposed projects, and the individual contribution of the proposed PCIs to sustainability under such scenarios.

text: (30) ACER recommends the Commission to inform RGs members on the scoring of the projects’ sustainability benefits in order to have clarity on how each project contributes to the sustainability goals.

text: (31) ACER sees a lack of criteria in the PCI assessment methodology for the allocation of points to PCI candidates’ costs in cases where the number of projects in the relevant RG is considered to be “very small”. ACER recommends to specify in the methodology clearly when and how points for costs are to be allocated to such projects, as the current definition seems to be too vague, making the replication of the scoring impossible. Commission should ensure consistent application of the criteria across regions, taking into account regional specificities where applicable.

text: (32) ACER recommends Commission to specify the benefit - cost threshold value in the PCI assessment methodology as applied in all Regional Groups, which means before the meeting where the final ranking of the projects is presented to the Regional Groups. A predefined benefit - cost threshold value would provide greater clarity of the criteria that candidate projects need to meet in order to be included in the draft regional PCI lists.

text: Assessment of the proposed PCIs in the draft Regional PCI lists

text: The NRAs reviewed and assessed the candidate PCIs between 22 January 2021 and 19 March 2021. The NRAs assessed 39 projects (34 at group level and 5 at individual level). For 22 PCI candidates, the relevant NRAs provided coordinated assessments.

text: (33) The NRAs assessed the inclusion of the PCI candidates in the National Development Plans, the cross border relevance of the project candidates, the compliance of the projects with the policy criteria provided in

text: Article 4(2)

text: (b) of

text: Regulation (EU) No 347/2013

text: , the consistency of the cost and benefit data provided by the project promoters, the merits of the qualitative project analyses, and the soundness of the projects’ implementation schedule, in particular the commissioning dates.

text: (34) ACER welcomes the fact that the draft regional PCI lists contain a much smaller th number of projects in comparison to the 4 PCI list, being reduced by approximately one third, which corresponds to the very limited needs for additional gas infrastructure in Europe in view of decarbonisation goals. ACER notes that the proposed draft gas st PCI list is now about 80% shorter than the 1 PCI list. ACER supports the need to very cautiously and selectively plan additional gas infrastructure in view of the evolving needs and energy policy priorities and to avoid potential redundancy in gas infrastructure, while, at the same time, focusing on proposed projects which can address identified needs in an efficient way.

text: (35) ACER notes the consistent application of a non-monetised benefit - cost threshold across RGs, with the threshold for the inclusion of a project in the draft regional PCI lists set to the value one (1). One inconsistency has been noted in NSI East where one of the projects with the scoring above the threshold (1) has not been proposed for the draft PCI list.

text: (36) ACER notes that no reasoning is provided for the candidate projects not included on the draft PCI list beyond the ones which had insufficient benefit - cost ratio. Candidate projects not meeting general or specific criteria and the ones with commissioning date before March 2022 should be listed as well with relevant justifications.

text: (37) Finally, in practical terms, ACER finds the draft PCI regional lists as submitted by the Commission at times challenging to understand. The projects’ names do not correspond to existing PCIs’ numbering or to the names of the candidate projects submitted for the Public Consultation. Therefore ACER recommends the Commission to align the projects naming and numbering with the ones used during Public Consultation and previous PCI list.

text: HAS ADOPTED THIS OPINION: 1. ACER notes that the draft Union PCI list demonstrates improvements in terms of:  Identifying infrastructure needs (reduction, simplification and alignment of indicators);  Applying a conservative approach to the consideration of the expected project benefits, whereby any project’s benefits exceeding the identified needs or benefits beyond a defined threshold are not considered;  Considering the sustainability aspect of the PCI candidates;  Extending the duration of the consultation periods;  Applying, for the purposes of the selection, an identical benefit - cost threshold value across all Regional Groups.

text: 2. ACER is unable to assess the consistent application of the cost-benefit analysis to all the candidate projects due to: a. Lack of sufficient transparency of the methodology for assessing the gas candidate PCI projects, notably: i. Lack of clarity about the PCI candidates’ contribution to each specific criterion and about the extent to which each PCI candidate addresses an identified need; ii. Unclear procedure for the calculation of cost scoring in the Regional Groups where the number of projects is very small. b. Non-replicability of the results of the application of the PCI assessment methodology.

text: 3. To help tackle the deficiencies listed above and enable ACER to perform its legal duty, the Regional Groups should continue their work on improving the transparency of the process and the methodology for assessing the gas candidate PCI projects, taking into account ACER’s recommendations included in this Opinion. Furthermore a great emphasis should be put on monetisation and quantification of benefits to the maximum possible extent.

text: A.1.1 PCI Cooperation Platform The Cooperation Platform was the main forum of discussion during the PCI selection process between the European Commission, ACER, NRAs, and ENTSOG. As a result of the discussions, concrete proposals were presented to the Regional Groups for use in their decisionmaking. The participants in the Cooperation Platform regularly discussed trilaterally key issues during numerous teleconferences held between March 2020 and July 2021. In certain instances, the participants in the Cooperation Platform expressed divergent views. In these instances, the final proposals to the Regional Groups were formulated by the European Commission. The joint work in the Cooperation Platform facilitated the development of a methodology for the identification of infrastructure needs and of the methodology for the assessment of PCI candidates. A.1.2 Identification of infrastructure needs The indicators used to identify the infrastructure needs were the following:

text: Security of Supply

text:  Curtailed Demand (CD);  Single Largest Infrastructure Disruption (SLID);

text: Market Integration and Competition

text:  Commercial Source Access (CSA);  Minimum annual supply dependence (MASD);

text: Sustainability

text:  Sustainability

text: Other

text:  Adaptation to high-calorific gas  Physical isolation  Access to a new source ACER considers such an exercise essential for identifying those regions and Member States where only infrastructure developments can solve an existing bottleneck and, consequently, where project promoters are expected to put forward project proposals. In order to facilitate the assessment of the proposed projects, promoters had to indicate, in the course of the call for PCI applications, which infrastructure need(s) their candidate project would address. A.1.3 Process schedule and main activities The European Commission convened an introductory and 4 regular meeting rounds of the gas Regional Groups between 17 November 2020 and 22 June 2020. The milestones of the PCI selection process are highlighted in the table below.

text: Table 1 - Main activities carried out in the framework of the Regional Groups in the PCI selection process

text: A.1.4 ENTSOG’s System Wide and the Project-specific CBA in the context of the PCI selection

text: For the purpose of PCI assessment, NRAs received the PS-CBA results on the staring date of nd the consultation, 22 January 2021. The results were based on the application of the 2 CBA Methodology . Depending on the maturity of each project, the PS-CBA assessment evaluated the impact of projects under different infrastructure levels , namely the “low infrastructure level” (existing infrastructure, as well as projects with final investment decision – FID - taken) and the “advanced infrastructure level”.

text: The impact of a given project was assessed by comparing the situations “with the project” and “without the project” (“incremental approach”) for each considered infrastructure level and for each scenario. Generally, benefits generated by projects tended to be higher in the low infrastructure level where the infrastructure grid is less developed (consisting of only existing infrastructure and FID projects), whereas in the case of the advanced infrastructure level, the infrastructure gaps may be already (partially) filled by possible competing projects.

text: For the purpose of the PCI selection process, PCI candidates were assessed only for the timeframe until 2030, in line with the EU 2030 targets. The assessment of PCI candidates was based on benefits calculated by using the TYNDP 2020 “National Trends” scenario. The infrastructure level used for the project assessments was the “low infrastructure level”. In the case of competing projects, the results calculated by using the advanced infrastructure level and timeframe until 2040 were considered.

text: Ultimately, only the non-monetised indicators from the PS-CBA were taken into account in a multi-criteria analysis and candidate project assessments. In ACER’s view, assessing the

text: benefits by only using non-monetised indicators essentially makes it impossible to demonstrate that a given project’s benefits exceed its cost.

text: A.1.5 TYNDP related issues – cost data, distinction of the TYNDP and the PCI selection process

text: As in past opinions, ACER reiterates that cost estimates for the candidate projects constitute an essential part of the project attributes, given the requirement to demonstrate that a candidate project’s benefits exceed its costs. As the potential overall benefits of the project must outweigh its costs , no substantive assessment of the fulfilment of this criterion can be carried out without a comparison of the project’s monetised benefits and its cost.

text: Regarding the criteria established in the Regulation which requires that a PCI candidate be included in the TYNDP, ACER points out that being included in ENTSOG’s TYNDP is a necessary, but not a sufficient condition for a project to be put forward as a PCI candidate. PCI candidates must contribute significantly to optimising EU’s gas network development by addressing clearly present needs, to the Union’s overall energy and climate policy objectives, and to the creation and the efficient functioning of the single gas market.

text: A.1.6 Establishment of project groups for the PS-CBA, treatment of maturity and of complementary and competing projects

text: As in the 2019 PCI selection process, candidate projects were grouped so that the CBA could assess the combined benefits for those projects which are complementary in nature. The grouping was circulated to NRAs on 22 January 2021. NRA assessments of the consistent application of the criteria and the CBA methodology , and the evaluation of the cross-border relevance of candidate projects were carried out on the basis of these project groups.

text: Annex 2. NRA assessment of candidate projects

text: In line with the provisions of Annex III 2(7) to

text: Regulation (EU) No 347/2013

text: , the NRAs cooperating in the framework of ACER checked the consistent application of the criteria and the CBA methodology and evaluated the cross-border relevance of the candidate projects for PCI lists. The NRA checks and evaluations were carried out between 22 January 2021 and 19 March 2021. The scope of the assessments covered the candidate projects and project groups. The summary of the assessment results was communicated to the Regional Groups on 22 April 2021 . The assessment included the following main elements:  Presence of the candidate projects in the National Development Plans of the hosting Member States;  Compliance with the criteria of cross-border relevance , in line with

text: Article 4.1

text: (c) of

text: Regulation (EU) No 347/2013

text: ;  Compliance with the specific policy criteria , in line with

text: Article 4.2

text: (b) of

text: Regulation (EU) No 347/2013

text: ;  Consistency of the indicated capital expenditure (CAPEX) and operational expenditure (OPEX) data of the project and the information available to the NRA from other sources;  Consistency and validity of the simulation results and the Economic Performance Indicators ;  Credibility of the qualitative analysis;  Whether the overall benefits by the project outweigh its costs;  NRAs’ own assessment of the realism of the indicated commissioning date; and  Objections (if any) to the inclusion of the candidate project in the draft regional PCI lists. The NRAs examined 34 PCI candidates at the Group level (out of the 41 in total) and 5 at individual level. Two projects being part of a project groups, TRA-A-302 (part of EAST 16A) and TRA-N-0066 (part of EAST_15), were assessed only on individual level. Additionally,

text: SGC_2b and 3b were assessed both at the group level, as well as (project TRA-A-0068) at individual level. All projects meet at least one of the specific policy criteria, with 21 of the assessed projects contributing to all four specific policy criteria. Regarding cross-border relevance, NRA indicated one project (ETR-N-20) as not being able to be assessed against criteria of

text: Article 4(1)

text: (c) of the

text: Regulation (EU) No 347/2013

text: . One candidate project (ETR-N-20) is not included in the NDPs of hosting Member State, and eleven are only partially included in the NDPs. By looking at other elements, NRAs confirmed for 22 of the candidate projects that the data for CAPEX is consistent. In 31 cases, NRAs saw as credible the candidate projects’ specific simulation results identifying benefits and in 34 cases NRAs evaluated positively a credibility of the qualitative analysis. As regards the planned commissioning dates, NRAs estimated that 21 of the assessed projects could be completed by the indicated deadline. For 12 of the assessed projects, NRAs indicated that their commissioning could realistically take place at a later date than the one indicated by the promoter, and for three projects the NRAs were unable to assess the credibility of the indicated commissioning date. Overall, the results demonstrate that more than half (26) of the NRAs consider that the overall benefits of PCI candidates outweigh its costs. The second most frequent reply (8) of NRAs was that they are not able to assess and in 5 cases NRAs expressed divergent views. ACER notes that Economic Performance Indicators were not provided by ENTSOG to NRAs, and that instead NRAs needed to request this data directly from the promoters if the NRAs wished properly to assess the candidate project. Consequently, in many instances the NRAs were unable to assess the projects or responded that no data had been provided.
