text: 1. INTRODUCTION (1) On 8 February 2022, the European Union Agency for the Cooperation of Energy Regulators (‘ACER’) received from the European Network of Transmission System Operators for Electricity (‘ENTSO-E’) its Research, Development & Innovation Implementation Report 2021-2025 (‘RDI Implementation Report 2021-2025’). The document identifies 13 RDI project concepts for TSOs to be deployed to deliver the targets of the ENTSO-E RDI Roadmap 2020-2030 .

text: 2. OVERVIEW OF THE RDI IMPLEMENTATION REPORT (2) ACER welcomes ENTSO-E’s efforts to focus the research, development and innovation (‘RDI’) plans of its TSO members through the RDI Implementation report 2021-2025, to deliver the targets of the ENTSO-E RDI Roadmap 2020-2030. (3) ACER notes that the path towards a net zero emissions by 2050 requires dynamic adaptation from Transmission System Operators (‘TSOs’). Having a coordinated pan-European approach to R&I activities allows to tap into synergies and avoid overlaps which can lead to more cost efficient tackling of the challenges ahead. (4) The RDI Implementation report 2021-2025 provides an overview of the planned RDI activities and defines tangible goals in terms of the Technology Readiness Level (‘TRL’) levels to be achieved typically ranging from `proof of concept` to a `prototype system`. (5) TSOs use different strategies and instruments for RDI activities. Although some have dedicated RDI departments, ACER believes most will chose to run RDI activities through third parties, such as research institutes, universities and other interested stakeholders. (6) Each of the 13 project concepts is attributed with a bottom-up budget estimate. ACER understands these estimates are for information only and do not pose any commitment on the TSO side to deliver results. In addition, there is no clear explanation on how these projects are to be financed, i.e. are TSOs counting on regulated financing or support schemes such as Horizon Europe. (7) The RDI Implementation report 2021-2025 was accompanied by a comprehensive stakeholder interaction report, providing both stakeholder comments and ENTSO- E’s reactions to them, HAS ADOPTED THIS OPINION:

text: 1. ACER recommends that ENTSO-E links the RDI Implementation Report 2021-2025 objectives, as well as the objectives of the broader scoped RDI Roadmap 2020-2030, with the TSOs’ core tasks . All proposed project concepts should have a clear and undisputable link to at least one of the core TSO objectives, explaining the future challenge for TSOs to fulfil these core tasks and how the project aims to solve the issue. TSOs should follow closely the RDI projects and already start considering possible technical, legal and other challenges related to the potential future wide scale implementation.

text: 2. ACER observes that the bottom-up budgetary planning seems difficult to abide and lacks a clear objective. We thus recommend ENTSO-E to either treat the budget estimates as indeterminable (thus remove them from the RDI Implementation Report), or improve their transparency, especially regarding how they were constructed and which TSOs committed to which project concepts. In addition, monitoring of real expenses should be implemented, to help keep track of investments.

text: 3. ACER observes there is no delegation of these project concepts amongst its members, which could help achieve a stronger commitment of TSOs towards achieving the projects’ specific goals. In addition, this would enable other stakeholders to have a clear contact to the project via its leading TSO in case of interest to cooperate. If such delegation is not possible, ACER recommends ENTSO-E to facilitate the much needed interaction between stakeholders interested in participating and the TSOs willing to do the same, potentially establishing a cooperation platform for such a purpose. This Opinion is submitted to ENTSO-E and the European Commission. Done at Ljubljana, on 5 May 2022. - SIGNED - Fоr the Agency The Director C. ZINGLERSEN

text: The Romanian NRA explains all the listed investments are included in the Romanian NDP and the NRA has not identified any inconsistency with the draft EU TYNDP 2022. In this Opinion, a project may be composed by one or more investments. The part of the draft EU TYNDP 2022 investment which belongs to a country is called ‘national part of an investment’. E.g. if an investment is an interconnector between countries A and B, it is considered that there are two national parts: one consisting of the part of the investment located in country A, and the other consisting of the part of the investment located in country B.

text: Investments 256 ‘New interconnection line BG-GR by a 153km single circuit 400kV OHL’, 1211 ‘HVDC Aragon region-Marsillon’, 1630 ‘AC Overhead Line Aach-Bofferdange’ and 1772 ‘Roost-Flebour-Bauler’ 11 The remaining 14 transmission projects are located in Bosnia, Egypt, Switzerland and United Kingdom and the remaining 3 storage projects in United Kingdom.

text: 2. PROCEDURE (10) On 25 November 2022, the Agency invited the NRAs of EU Member States and other NRAs participating in the relevant Agency’s working structures to review projects and corresponding investments in the already published version of the draft EU TYNDP 2022 which are located on the territory of their country and assess them, including their consistency with projects in NDPs. (11) On 31 January 2022, ENTSO-E submitted the draft EU TYNDP 2022 to the Agency. Following the formal submission of the draft TYNDP 2022 by ENTSO-E to the Agency, the Agency consolidated its findings based on the data corresponding to the formal submission. (12) In this regard, the Agency notes that the publicly consulted version of the draft EU TYNDP 2022 does not include transmission investments 1832, 1833, 1834, 1835 and 1836 (all belonging to project 259 ‘HU-RO’ interconnection), which appear in the version submitted to the Agency. Based on the information provided by the Romanian NRA, all these investments were reported under investment number 1205 in the publicly consulted version, but following the TSO’s request at the end of 2022, the investments were separated. In addition, investment 1826 (at least under this code) has been removed compared to the publicly consulted version. (13) NRAs have provided the Agency with specific information on the national parts of transmission investments and storage projects that are/were:  included in the draft EU TYNDP 2022,  included in the EU TYNDP 2020, but not in the draft EU TYNDP 2022 and  cross-border relevant and appear in their NDPs, but not in the draft EU TYNDP 2022. (14) The data collection from NRAs was completed on 14 March 2023. By this date, NRAs from 27 EU Member States and one EEA Member State (Norway) provided input to the Agency. The list of the participating countries along with the number and share of the reviewed transmission investments and storage projects is presented in Table 8 in Annex I.

text: PUBLIC

text: Opinion No 04/2023

text: (15) Out of the 314 transmission investment items and storage projects included in the draft EU TYNDP 2022, the Agency reviewed NRA responses for 262 investments regarding their consistency with the latest national development plans. 58 investment items belong to more than one country and are, therefore, reviewed by more than one NRA, leading to a total assessment of 348 national parts of transmission investments and storage projects (325 investment items and 23 storage projects). 3. GENERAL INFORMATION ABOUT THE PROJECTS IN THE DRAFT EU TYNDP 2022 (16) The draft EU TYNDP 2022 contains an assessment and a description of 141 transmission projects, with 291 corresponding investment items and 23 storage projects. The Agency notes that additional four transmission and three storage projects applied for inclusion in the draft EU TYNDP 2022, but were rejected due to non-compliance with the draft EU TYNDP 2022 project Inclusion Guidelines (‘Inclusion Guidelines’). Table 1 illustrates the number of transmission projects and investments as well as storage projects of the draft EU TYNDP 2022 compared to the previous four EU TYNDPs.

text: (18) The Agency acknowledges the reduction of the average number of investment items per project over time which is considered a positive sign of increased efforts to avoid over clustering of investments. (19) Table 3 represents the total number as well as the total costs of transmission investment items and storage projects according to their status, as provided in the draft EU TYNDP 2022 project sheets.

text: Total 282 133.89 23 8.84

text: (20) The Agency notes that in 2022, the declining trend of the number of transmission investments and the related costs in the EU TYNDP since 2016 further continues . While the share of investments in advancement status ‘under consideration’ remains at 30% and ‘in permitting’ around 25%, the shares of the ‘planned, but not yet in permitting’ and ‘under construction’ slightly changed, i.e. increased by 6 % and decreased by 5 % respectively. Moreover, the number of storage projects in the draft EU TYNDP 2022 slightly decreased after its increase two years ago and the corresponding costs almost halved.

text: The average number of investments per project has gradually decreased from 2.92 for the TYNDP 2014 to 2.06 for the draft TYNDP 2022. For TYNDP 2020, the average number was 2.08. 9 investments are not included in the table, because according to the information provided in the draft EU TYNDP, they have already been completed or commissioned. 8 The total transmission investment cost does not include the total cost of investments 474 ‘Substation Ribeira de Pena’ and 1214 ‘Ejea de los Caballeros substation’ and operational expenditure (OPEX) of investments 1785 ‘Inkoo-Hikiä’, 1810 ‘HVDC converter stations and cables’, 1811 ‘Offshore Wind Connection Centre Manche 2’, 1812 ‘Offshore Wind Connection South Britanny’, 1808 ‘AO6 Occitanie’, 1809 ‘AO6 Occitanie’ and 1813 ‘Offshore wind connection South Atlantic’ which are not reported or reported to be 0 EUR in the draft EU TYNDP 2022. For an assessment of whether the investments of the draft EU TYNDP 2022 are sufficient to reach the decarbonisation objectives, please refer to the Agency’s Opinion 03/2023 and the TYNDP 2022 System Needs Study carried out by ENTSO-E.

text: Opinion No 04/2023

text: (21) The Agency notes that the draft EU TYNDP 2022 reports 27% of these investments are new, 45% are on time, 3 % are ahead of time, 14% are delayed and 11 % are rescheduled compared to the TYNDP 2020. (22) The Agency finds that at least one interconnection investment, i.e. investment 1772 ‘Roost-Flebour-Bauler’ has a different status across the borders. In Luxembourg, the national part of the investment is completed, while in Germany it is ‘planned, but not yet in permitting’. A difference in investment status across borders does not necessarily constitute an inconsistency, but could point to limited cross-border coordination, which may be improved. (23) The Agency also identified some interconnections (which have been fully monitored in this Opinion and already achieved at least ‘planned, but not yet in permitting’ status) for which NRAs indicated different commissioning dates for the implementation of their national parts . However, in none of these instances the difference exceeds one year. Also here, the Agency notes that the smaller difference across commissioning dates is not necessarily an inconsistency, though the Agency would expect commissioning dates of interconnectors to be reasonably aligned. (24) A total number of 92 transmission investments and 10 storage projects were present in the TYNDP 2020 but not in the draft EU TYNDP 2022. Out of these, 78 transmission investments and 7 storage projects are at least partly located on the territory of an EU or EEA Member State. Out of these 78 transmission investments and 7 storage projects, approximately 30% are commissioned and another 30% cancelled. Around 10% were not compliant to the Inclusion Guidelines, while the remaining are still under development or their status is not available to the NRA. (25) In addition to the cross-border relevant investments identified by NRAs during former investment review activity (which are neither included in the TYNDP 2020 nor in the draft EU TYNDP 2022), the participating NRAs reported on six cross-border relevant investments not included in the draft TYNDP 2022, but in the relevant NDPs. (26) For about 51% out of the 291 transmission investment items in the draft EU TYNDP 2022, the NRAs indicated no difference between the features of the investment as included or present in the latest NDP and the draft EU TYNDP 2022 (or the difference resulted from the fact that their NDP is outdated). For about 20%, at least some difference was identified. Approximately 29% were not able to be assessed on any aspect by the NRAs mainly due to their absence in the NDP. These investments are listed in Table 9 in Annex I. Most of them are in a very early stage of development.

text: (27) Figure 1 represents the shares of various inconsistencies between the information provided in the draft EU TYNDP 2022 and the latest NDPs, as indicated by the NRAs. The main inconsistency between transmission investment items included in the latest NDP and draft EU TYNDP 2022 is a different expected commissioning (23 instances), followed by different costs (20 instances), different clustering (13 instances), different status (13 instances), different progress (6 instances) and technical features (4 instances). Detailed information is provided in Table 10 in Annex I.

text: Clustering Costs 15% 24%

text: Commissioning date Progress (and 28% the reason) 7% Status 16%

text: (28) The Agency acknowledges that the NDPs and the EU TYNDP may temporarily be misaligned due to different schedules for the elaboration of the plans and other reasons (e.g. changes in market fundamentals), which, to some extent, can explain the identified differences and does not necessarily constitute an inconsistency between the plans. (29) For vast majority of investments with a clearly identified difference in the commissioning dates , the commissioning date reported in the draft EU TYNDP 2022 was an earlier date compared to the NRA’s information. Furthermore, for half of the (non-yet commissioned) investments with different advancement status, NRAs identified a more advanced status in the draft EU TYNDP 2022 compared to their information.

text: Not accounting for those instances where the NRA provided a range for the commissioning date matching also the date provided in the draft TYNDP 2022 or where the NRA flagged a difference without providing a commissioning date.

text: PUBLIC

text: Opinion No 04/2023

text: (30) Regarding storage projects, the Agency notes that no difference has been identified by the NRAs for 4 projects and the remaining projects the NRA was not able to assess. (31) In order to increase the accuracy of the project and investment data of the draft EU TYNDP 2022, the Agency considers it important that the NRA scrutiny of the projects provided in Annex I to this Opinion, is taken into account for the final EU TYNDP 2022, as appropriate. 4. ASSESSMENT OF THE PROJECTS IN THE NDPS AND THE EU TYNDP Investments in the draft EU TYNDP 2022 which are not included in the respective NDP(s) (33) The Agency welcomes the improved transparency regarding the information on the inclusion of a specific project in the respective NDPs (e.g. inclusion of this information in the excel project sheets, provision of the reasons for non-inclusions for some projects), however, it regrets that information on the non-inclusion along with the corresponding reason is not provided for all projects. (34) According to the information provided by NRAs, 80% of the 325 national parts of transmission investments are included in the relevant NDPs , while 20% are not. The summary of reasons for these absences is provided in Figure 2. The most common reason for the absence is an earlier elaboration of the NDP than of the draft EU TYNDP (19 instances), followed by the commissioning date of the investment being beyond the time span of the NDP (15 instances), an insufficient advancement of the investment (12 instances), the investment having been commissioned (10 instances), the investment appertaining to a non-TSO project while such projects are normally not included or present in NDP (9 instances). Additional information is provided in Table 11 in Annex I.

text: commissioning date beyond the an earlier elaboration of the time span NDP 23% 29% non-TSO project or a storage insufficient project advancement 14% 19% commissioning 15%

text: (35) Regarding the storage projects, 17 projects out of the 23 are not included in the relevant NDPs , mainly because they appertain to a non-TSO storage project (14 instances). The remaining absences are due to an earlier elaboration of the NDP than of the draft EU TYNDP 2022 (2 instances) and an insufficient advancement of the project (e.g. study not having turned into a project yet). More detailed information is provided in Table 12 in Annex I. (36) The Agency reiterates its view that actual implementation of the EU TYNDP transmission projects strongly relies on the NDPs. Non-inclusion of a transmission project (or part of it) in the NDP due to other reasons than the commissioning of a project, cancellation of a project, time difference in the elaboration of the plans or the limited scope of the NDP (e.g. when it does not include third-party projects) raises doubts about the credibility and feasibility of the implementation of the concerned projects. Therefore, the reason for non-inclusion in the NDP is an important information regarding the TYNDP transmission projects. Project’s non-inclusion in the NDP should clearly be flagged and the reason for such absence should be provided in the EU TYNDP. Further, the Agency recalls its view that the NDPs’ scope should include third-party projects .

text:  Hungarian-Romanian AC line ‘Installation of the second circuit of Békéscsaba (HU) – Nadab (RO) 400 kV cross-border line’,  Italian-French AC line ‘Voltage upgrade Nava (IT) – S. Dalmas (FR)’. Table 13 in Annex I provides additional information on these investments. (40) The Agency notes that under the current EU TYNDP process, the inclusion of cross border relevant projects in the EU TYNDP solely depends on project promoters’ (‘PP’) voluntary applications, with a risk to bypass the EU-level scrutiny of a project, if the PP does not apply for inclusion in the EU TYNDP. (41) In line with its previous recommendation , the Agency stresses that all the planned projects with cross-border relevance from the NDPs should be included in the EU TYNDP, and that cross-border relevant projects in the NDPs should be flagged explicitly. Investments of TYNDP 2020 which are not present in the draft EU TYNDP 2022 and other cross-border relevant investments not included in the draft EU TYNDP 2022 (42) A list of transmission investments and storage projects that were included in the EU TYNDP 2020, but are neither included in the draft EU TYNDP 2022 (nor is their absence explained by ENTSO-E) is provided in Tables 14 and 15 in Annex I. The Agency identifies a total of 78 such transmission investments and seven storage projects on the territory of EU and/or EEA Member States . (43) Based on the information provided by the NRAs, the Agency identified that about one third of these investments (located in EU Member States and/or Norway) is already commissioned and another third cancelled. Approximately 10% failed to meet the criteria from the Inclusion Guidelines and the remaining share is still under development, postponed indefinitely by the PP or their status is not available to the NRA. (44) The Agency notes that two storage projects that were included in the EU TYNDP 2020 were not included in the draft EU TYNDP 2022 due to their non-compliance to the Inclusion Guidelines. Furthermore, the Irish NRA explained that project 1030 “Mares Organic Power Energy Storage” was not included in the draft EU TYNDP 2022, because it had been cancelled. For the remaining four storage projects located in EU Member States that are not present in the draft EU TYNDP 2022, NRAs were not able to provide information, mostly due to that fact that the project is a non-TSO project and the promoters have no reporting obligation to the NRA.

text: (45) The Agency is of the view that all commissioned and cancelled investments should enter the subsequent EU TYNDP for monitoring purposes (i.e. without a CBA assessment). For the remaining investment which are no longer included in the draft EU TYNDP 2022 in comparison to the previous edition, a valid explanation for their non-inclusion should be provided in order to ensure appropriate transparency. Projects which were rejected to be included in the draft EU TYNDP 2022 due to non-compliance with the ENTSO-E TYNDP Inclusion Guidelines (46) The Agency notes that four transmission and three storage projects applied for inclusion in the TYNDP 2022, but were rejected due to non-compliance with the Inclusion Guidelines. These projects and the reasons for non-compliance are listed in table 5.

SHORTCOMINGS OR PRACTICAL MISTAKES REGARDING PROJECTS IN THE DRAFT EU TYNDP 2022 Investment numbers (47) Based on the information provided by NRAs, the Agency notes that at least four transmission investments from the EU TYNDP 2020 appear under new investment numbers in the draft EU TYNDP 2022. These investments are clustered differently in the draft EU TYNDP 2022 and they are listed in Table 6.

text: (49) The Agency is of the view that applying non-unique project identification numbers (even if one of them is a transmission and the other one is a storage project) or not consistently applying the investment codes across the EU TYNDPs, negatively impacts the EU TYNDP transparency and adds substantial complexities to the EU TYNDP-related

text: processes (e.g. monitoring, project consistency assessment, project data comparison for specific purposes). Investment costs  for mature investments, the costs should be reported together with a clearly explained uncertainty range, while for non-mature investments, this principle should be applied in case detailed project cost information is available,  in the absence of the availability of the detailed project cost information, for investments ‘planned but not yet in permitting’ or ‘under consideration’, a set of standard investment costs with a project-specific complexity factor needs to be used,  regarding the reported CAPEX , it should be comprised of two parts: ‘inception CAPEX’, indicator C1a, which is ‘the capital costs incurred at the inception of the project’, and ‘sustaining CAPEX’, indicator C1b, which is the ‘capital expenditure incurred during the assessment period that is necessary to ensure that the functionality of the original assets realised by the inception CAPEX is maintained’. Currently, overall numbers are provided for the CAPEX, but given that the two categories of costs are incurred at different points in time, affecting the overall cost estimate of the project, they should be reported as distinct figures. (51) The Agency notes contrary to the requirements of the Inclusion Guidelines, for nine transmission investments in the draft EU TYNDP 2022, information on the capital expenditures (CAPEX) and/or the operating expenses (OPEX) is missing (e.g. provided as zero). Moreover, the Agency notes that 7 more mature (i.e. of status ‘in permitting’ or ‘under construction’) transmission investments and three storage projects lack information on the cost uncertainty range. The list of these investments and storage projects is provided in Table 16 in Annex I. (52) The Agency notes that the draft EU TYNDP 2022 provides no information indicating for which projects or investments the standard costs were actually used.

text: Clustering of investments (53) The Agency welcomes an increased completeness of information regarding the necessity for clustering of projects in comparison to its completeness in the EU TYNDP 2020 . However, six projects with more than one investment in the draft EU TYNDP 2022 remain without an explanation for the necessity of clustering. These projects are listed in Table 17 in Annex I. (54) According to the CBA 3.0 Guideline and Implementation Guidelines for TYNDP 2022 rd based on 3 ENTSO-E guideline for CBA of grid development projects (‘Implementation Guidelines’) , investments clustered within the same project can at most be one project status level apart from each other. (55) The Agency notes that project 170 ‘Baltic States Synchronization with Continental Europe’ in the draft EU TYNDP 2022 contains (not-yet commissioned) investments that are more than one project status level apart from each other, i.e. its least mature investment is ‘under consideration’ and its most mature (not-yet commissioned) investment is ‘under construction’. (56) The Agency recalls that the clustering of investments should be carried out in line with the CBA 3.0 Guideline and the Implementation Guidelines. (57) The Agency notes that for six project in the draft EU TYNDP 2022, project’s status does not correspond to the status of their least mature investment. These projects are listed in Table 18 in Annex I. In the Agency’s view, status of the project should be consistent to the status of its least mature investment. Information on the progress of investments (58) The Agency welcomes that the expected commissioning date for each investment also includes the month, not only the year, which makes these data more informative and increases consistency with several related activities of the Agency. (59) The Agency identified inconsistencies in the information regarding the progress of the investments since 2020. There are 66 new investment numbers in the draft EU TYNDP 2022 and out of them, 17 investments are not labelled as ‘new’, thus either the investment number has changed for a previously included investment (e.g. as it is the case for

text: PUBLIC

text: Opinion No 04/2023

text: investment 1783 and 1784) or the progress data is incorrect and should be ‘new investment’. These investments are listed in Table 19 in Annex I. (60) Furthermore, 30 transmission investments are labelled both in the TYNDP 2020 and in the draft TYNDP 2022 as ‘new investment’. (61) In at least 30 instances, the commissioning year of the investment does not match the progress of the investment when comparing information provided in the TYNDP 2020 and draft TYNDP 2022. 24 investments are labelled as ‘on time’, but appear to be delayed, while six investments appear to be ‘ahead of time’ when comparing the commissioning years from the TYNDP 2020 with the information in the draft TYNDP 2022. These investments are listed in Table 20 in Annex I. Additional shortcomings or practical mistakes regarding projects of the draft EU TYNDP 2022 (62) The Agency’s review of the projects in the draft EU TYNDP 2022 identified some investments for which the draft TYNDP 2022 did not provide the correct list of hosting countries:  Projects 123 (‘LitPol Link Stage 2’) and 138 (“Black Sea Corridor”) are reported as internal projects, although they appear to be located on the territory of more than one country.  Project 346 (‘ZuidWest380 NL Oost’) is an internal project in the Netherlands, however, Belgium is also reported under this project in the draft EU TYNDP 2022. (63) Finally, for some investments (listed in Table 21 in Annex I) the draft TYNDP 2022 fails to provide sufficiently concrete investment description. The Agency is of the view that for the sake of transparency and robustness of the EU TYNDP, a sufficient description of each investment in the EU TYNDP should be provided. HAS ADOPTED THIS OPINION: 1. The Agency finds that the draft EU TYNDP 2022 assessments and the projects included in it generally contribute to the objectives of non-discrimination and effective competition, referred to in Article 32(2) of Regulation No 2019/943.

text: 2. However, as pointed out in its Opinion 03/2023, the Agency considers that the draft TYNDP 2022 does not sufficiently contribute to the efficient functioning of the market and secure functioning of the internal electricity market due to a number of shortcomings and addresses a number of recommendations to ENTSO-E, as regards the finalisation and adoption of the TYNDP 2022. 3. Further, in line with

text: the Agency identified a number of inconsistencies between an NDP and the draft EU TYNDP 2022 as provided in the recitals of this Opinion. It is recommended that ENTSO-E further enhances the consistency between the NDPs and the EU TYNDP by implementing the following measures: a. ENTSO-E should further increase its efforts to include all planned projects with cross-zonal relevance from the NDPs in the EU TYNDP. b. ENTSO-E should ensure that each investment included in the EU TYNDP and not included in the NDP of a hosting Member State is clearly flagged in the EU TYNDP and the reason for such absence should also be provided. c. All the commissioned and cancelled investments included in a previous EU TYNDP should enter the subsequent EU TYNDP for monitoring purposes (i.e. without a CBA) and each EU TYNDP should provide a list of investments which are no longer included in the EU TYNDP compared to the previous edition, together with an explanation for their non-inclusion. d. ENTSO-E should ensure that the information on investments’ status and commissioning date are sufficiently credible. Overly optimistic projections of the expected commissioning dates should be avoided. ENTSO-E should define certain reference project timelines (e.g. number of years for permitting and construction periods). For projects whose status is ‘under consideration’ or ‘planned but not yet in permitting’, future EU TYNDPs should provide the project promoter’s estimate together with the estimation of ENTSO-E based on the reference timeline. In case of differences, the project promoters should provide an explanation. e. ENTSO-E should ensure that all investments and projects in the EU TYNDP 2022 respect the criteria for clustering laid down in the CBA 3.0 Guideline and in the Implementation Guidelines. ENTSO-E should revise the clustering and demonstrate the necessity for clustering with regard to the draft EU TYNDP 2022 projects identified in section 5.3 of this Opinion. f. The Agency invites ENTSO-E to improve the costs-related information in the EU TYNDP by: i. including information on CAPEX and OPEX for all transmission investments and storage projects, ii. including the cost uncertainty ranges at least for all projects whose status is ‘in permitting’ or ‘under construction’,

text: PUBLIC

text: Opinion No 04/2023

text: iii. reporting inception CAPEX (i.e. the capital costs incurred at the inception of the project) and sustaining CAPEX (i.e. capital expenditure incurred during the assessment period that is necessary to ensure that the functionality of the original assets realised by the inception CAPEX is maintained) separately, iv. including information on how the costs were determined for each transmission investment or storage project (i.e. by using standard costs or detailed cost information and how the cost data was derived). g. ENTSO-E should consider the differences between the NDPs and the draft EU TYNDP 2022 identified by NRAs and update the draft EU TYNDP 2022 by taking into account the information and comments provided by NRAs in Table 10 in Annex I, as appropriate. ENTSO-E should also review and eliminate the project-specific inconsistencies in the draft EU TYNDP 2022 reported in section 5 of this Opinion. h. ENTSO-E should improve transparency and robustness of the EU TYNDP by ensuring that a sufficient level of technical information is provided for each investment, including those investments in the draft EU TYNDP 2022 which are listed in Table 21 of this Opinion. i. ENTSO-E should apply a unique coding for investments and projects in the EU TYNDP. j. ENTSO-E should, for the purpose of consistency with the previous EU TYNDP, review the information in the draft EU TYNDP 2022 regarding the investment progress since the EU TYNDP 2020 and adjust it where necessary. 4. In order to increase the robustness, credibility and transparency of the NDPs, the Agency recommends that the parties responsible for their development, review and adoption take into account the following measures and pursue their implementation to the extent it is in their powers: a. The NDPs’ scope should be expanded to allow the inclusion of third-party projects, where this is not yet the case. b. Cross-zonal relevant projects in the NDPs should be flagged explicitly. c. The differences between the NDPs and the draft EU TYNDP 2022 identified by NRAs should be considered and the NDPs should be updated by taking into account the information and comments provided by NRAs in Table 10, as appropriate. d. In case of interconnection investments, where the national parts are in different advancement status across the borders, the relevant parties should jointly review the concerned interconnection investments and, in case of inconsistencies, amend the respective planning and implementation plans.

text: The German NRA reports the project is completed, while the Dutch NRA reports that according to the latest NDP, the NL part of the project is rescheduled to 2023. The Dutch NRA explains the investment has partially already been commissioned and the remaining part is under construction The Austrian NRA explains the investment has been completed, but is not yet in operation. The Italian NRA further explains there are some pending upgrades planned to be completed in 2023 and that delays occurred due to construction-related complexities. The Dutch NRA explains investment has partially been commissioned and for the remaining part (i.e. Zwolle- Hengelo), a new needs assessment will be carried out. The German NRA explains the project was not included in the last three NDPs. The Czech NRA explains majority of investments of Project of Common Interest ‘National line Přeštice - Kočín’ has already been commissioned and this investment is scheduled to be completed in 2023. The Polish NRA explains the investment is present in the NDP and its implementation is crucial for the evacuation of power from offshore wind energy and for the improvement of the reliability of power supply to consumers in the Lubuskie Voivodeship.
