text: Opinion No 04/2021

text: (9) In parallel , the Agency invited the NRAs to review projects and corresponding investments in the draft EU TYNDP 2020 which are located on the territory of their country and assess them, including their consistency with projects in NDPs. (10) NRAs have provided the Agency with specific information on the national parts of transmission investments and storage projects in the draft EU TYNDP 2020 and on those investments with cross-border relevance, which appear in their NDPs but not in the draft EU TYNDP 2020. (11) The data collection from NRAs was completed on 28 March 2021. By this date, 27 NRAs (including 26 EU Member States and 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 6 in Annex I. 3. GENERAL INFORMATION ABOUT THE PROJECTS IN THE DRAFT EU TYNDP 2020 (12) The draft EU TYNDP 2020 contains a description and assessment of 154 transmission projects, with 321 corresponding investment items, and 26 storage projects. Table 1 presents the numbers of transmission projects and investments as well as of the storage projects in the draft EU TYNDP 2020 and in the three previous EU TYNDPs. Table 1. Number of transmission and storage projects in the draft EU TYNDP 2020 and in the three previous EU TYNDPs

text: (13) The overall investment costs of the transmission and storage projects in the draft EU TYNDP 2020 are presented in Table 2, according to their status provided in the draft EU TYNDP 2020 project sheets.

text: On 10 February 2021, the NRAs were requested to start review the investments included in the already published draft EU TYNDP 2020 project sheets. 4 In this Opinion the part of the draft EU TYNDP 2020 investment which belongs to a country is called “national part of an investment”. E.g. if a project or investment consists of an interconnector between countries A and B, and an investment item located in country A, it is considered that there are two national parts: one consisting of the part of the interconnector and the investment item located in country A, and the other consisting of the part of the interconnector located in country B.

text: Opinion No 04/2021

text: (14) The Agency notes that the number of transmission investments slightly decreased, while the total investment costs remained about the same in comparison with the draft EU TYNDP 2018 . The share of investments in different advancement status only slightly changed. About 30% of the investments are under consideration, 25% planned, but not yet in permitting, while 45% are more advanced (i.e. in permitting or already under construction) . Table 2.

text: 4. ASSESSMENT OF THE PROJECTS IN THE NDPS AND THE EU TYNDP Investments in the EU TYNDP 2020 which are not included in the respective NDP(s) (16) The Agency welcomes that the draft EU TYNDP 2020 provides, for each project, the list of the NDPs which include the respective project, but regrets that the projects in the draft EU TYNDP 2020, which are not included in any NDP and the reason for their non-inclusion, are not clearly flagged.

text: Total transmission investment cost of 136.441 million EUR is reported in the Agency’s Opinion No 11/2019, excluding the costs of 9 investments for which the values were not provided in the draft EU TYNDP 2018. Compared to the TYNDP 2018, the share of the investments that are “under construction” and “under consideration” increased by 4% and 6%, while the percentage of those “in permitting” decreased by 9%. The share of investment with the advancement status “planned, but not yet in permitting” only changed for 1%. Investment 1565 (‘Reconstruction of 330 kV OHL LE-Vilnius’) of project 170 (‘Reconstruction of 330 kV OHL LE-Vilnius from single-circuit into double-circuit’) is not included in the table, because it is already commissioned. Its cost reported in the draft EU TYNDP 2020 is 0.02 billion EUR.

text: Opinion No 04/2021

text: (17) Out of the 355 national parts of transmission investments, the NRAs confirmed that 275 national parts (or 77%) are included in the relevant NDPs and 80 national parts (or 23%) are not included in the relevant NDPs. (18) Figure 1 presents the summary of the reasons why some draft EU TYNDP 2020 transmission investments are absent from the relevant NDPs. The most common reasons for a draft EU TYNDP 2020 transmission investment’s absence in the NDP are the same as in EU TYNDP 2018, namely the investment is insufficiently advanced for entering the NDP or the commissioning date of the investment is beyond the NDP’s time span. In 19 instances the investment is not included in a relevant NDP because it corresponds to a third-party project and in that specific country third-party projects are generally not included in the NDP. Figure 1: Reasons for the EU TYNDP 2020 transmission investments' absence in the NDPs

text: The investment is not included, The investment is not because the latest NDP was advanced enough to be elaborated earlier than the draft other included in the NDP (e.g. TYNDP. reason study has not turned into a 4% 10% project yet). 29% The investment appertains to a non-TSO project and non-TSO projects are normally not included or present in the NDP. 24% The commissioning date of the investment is The investment has beyond the time span of been cancelled. The investment has the NDP. 1% been commissioned. 25% 7%

text: (19) Out of the 22 assessed storage projects, approximately third of them are included in the relevant NDPs. The remaining storage projects are not included in the NDPs due to general non-inclusion of the storage projects in the NDPs of the concerned countries. (20) Transmission investments or storage projects excluded from the relevant NDPs are listed in Table 7 and Table 8 in Annex I, according to the reasons for their absence. (21) In the Agency’s view the 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 and therefore the reason for non-inclusion in the NDP is an important information regarding the TYNDP transmission projects.

text: Opinion No 04/2021

text: (22) The Agency recommends ENTSO-E that in those instances where a transmission project (or part of it) is not included in the NDP of a hosting Member State, this feature should clearly be flagged and the reason for such absence should be provided in the EU TYNDP. (23) The Agency reiterates its view that the NDPs’ scope should be expanded to allow the inclusion of third-party projects, where it is not yet the case . Investments with cross-border relevance not included in the draft EU TYNDP 2020 (24) NRAs reported on the following 5 projects, which have cross-border relevance and are included in an NDP as a planned or more advanced investment, but do not appear in the draft EU TYNDP 2020: a. Italian-Swiss interconnection “Italy - Switzerland S. Giacomo project’ (planned, but not yet in permitting); b. Italian-Austrian interconnection ‘Dobbiaco (IT) – Austria (AT)’ (planned, but not yet in permitting); c. Italian internal project ‘Volpago substation’ (planned, but not yet in permitting); d. Italian-French interconnection ‘HVDC Italy France’ (under construction); e. Romanian internal project ‘OHL 400 kV s. c. Oradea Sud-Nadab’ (commissioned); (25) Additionally NRAs flagged the following under consideration projects, which have cross-border relevance, while they do not appear in the draft EU TYNDP 2020: a. Cypriot-Egyptian interconnection ‘Euroafrica interconnector’; b. Romanian internal project ‘OHL 400 kV s.c. Gadalin-Suceava’; c. Romanian-Moldavian interconnection ‘OHL 400 kV s. c. Suceava-Balti’; d. Romanian-Hungarian interconnection ‘OHL 400 kV Nadab-Bekescsaba circ.2 and 400 kV Nadab substation works’ (26) Additional information about the above projects is provided in Table 9 in Annex I.

text: Opinion No 04/2021

text: (27) Based on the information published on ENTSO-E’s website , the interconnection project between Cyprus and Egypt “Euroafrica interconnector” applied for inclusion in the EU TYNDP 2020 after the submission deadline and was rejected by the ENTSO-E for this reason. (28) The Agency notes that under the current EU TYNDP process, the inclusion of crossborder relevant projects in the EU TYNDP solely depends on project promoters’ voluntary applications, with a risk to bypass the EU-level scrutiny of a project, if the project promoter does not apply for inclusion in the EU TYNDP. (29) In line with its previous recommendation, the Agency stresses that ENTSO-E should include all the planned projects with cross-border relevance from the NDPs in the EU TYNDP , and that cross-border relevant projects in the NDPs should be flagged explicitly . Investments of TYNDP 2018 which are not present in the draft TYNDP 2020 (30) The Agency notes that there are 92 transmission investments which were included in the EU TYNDP 2018, but are neither included in the draft EU TYNDP 2020, nor is their absence explained by ENTSO-E. (31) Based on the information provided by the NRAs, the Agency identified that about one third of them are either cancelled or commissioned. They are presented in Table 10 and Table 11, while the remaining investments are listed in Table 12 in Annex I. (32) 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). (33) For the remaining investments which are no longer included in the draft EU TYNDP 2020 in comparison to the previous edition, ENTSO-E should provide a valid explanation for their non-inclusion. Projects in the draft EU TYNDP 2020 proposed to be excluded (34) Based on the information published on ENTSO-E’s website , the project “Online Grid Controller PSKW-Rio” applied for inclusion in the EU TYNDP 2020 after the submission deadline and was rejected by the ENTSO-E for this reason. However, the

text: PUBLIC

text: Opinion No 04/2021

text: project appears to be finally included in the draft EU TYNDP 2020 despite its initial rejection and without a reasoning provided by ENTSO-E. (35) The lack of such a reasoning behind ENTSO-E’s decision to finally include this project in the draft TYNDP 2020 reduces the transparency of the process and hinders the Agency’s evaluation of whether the ‘TYNDP Inclusion Guidelines’ have been consistently applied by ENTSO-E. (36) Further the Agency notes that based on the information provided by NRAs’ the following projects do not seem to meet the required administrative or technical criteria set by the ‘TYNDP Inclusion Guidelines’, while they are included in the draft TYNDP 2020: a. Based on the information provided by the Danish NRA 1051 ‘Aminth Energy ltd’ in the draft EU TYNDP 2020 does not meet any additional administrative criteria set by the ‘TYNDP inclusion guidelines’. b. Based on the information provided by the French NRA storage project 1042 ‘Distributed network of Hydrogen storage and production by electrolysis with re-electrification through a fleet of FCEVs’ in the draft EU TYNDP 2020 does not meet the technical criteria set by the ‘TYNDP inclusion guidelines’, in particular criterion related to ‘Voltage Level’. Regarding the voltage level, the NRA concluded based on the data provided on the production units’ capacity that connection to HTB 1 network will be required, accommodating a voltage between 63 kV and 90 kV which is under the threshold of 110 kV. Additionally, regarding ‘Capacity & Generation’ criteria, the data provided in the draft EU TYNDP 2020 does not allow to conclude the threshold will be reached. c. Based on the information provided by the French and the Spanish NRAs project 296 ’Britib’ in the draft EU TYNDP 2020 does not meet any additional administrative criteria set by the ‘TYNDP Inclusion Guidelines’. (37) As pointed out in its Opinion 03/2021, the Agency considers that the ‘TYNDP Inclusion Guidelines’ can serve the objectives of transparency and non-discrimination and eventually improve the quality and credibility of the TYNDP, if they are duly and consistently applied by ENTSO-E. (38) Therefore ACER recommends to remove the above listed projects from the TYNDP 2020, if they do not meet the criteria set by the TYNDP Inclusion Guidelines. Project differences in the draft EU TYNDP 2020 and in NDPs (39) NRAs carried out an assessment of the draft TYNDP 2020 projects, including the identification of potential inconsistencies between the draft EU TYNDP and the NDPs. The identified differences between the EU TYNDP data and the NRAs’ information for transmission investments and storage projects are presented in Table 13 and Table 14 in Annex I.

text: PUBLIC

text: Opinion No 04/2021

text: (40) Figure 2 presents the summary of the identified differences. Similar to the findings with respect to the previous EU TYNDPs , most of the identified differences are related to the commissioning date or costs, followed by the status, clustering, transfer capacities, technical descriptions and benefits. Figure 2: Summary of the identified differences (41) The Agency notes that the NRAs reported differences for approximately 9 % and no differences for approximately 53 % of the data assessed in this Opinion. For the remaining share of the data, the NRAs are not able to assess the consistency between the draft EU TYNDP 2020 and the respective NDP. (42) At least one substantial difference in the data has been identified for 114 (or 30 %) of national parts of transmission investments and storage projects from the draft EU TYNDP 2020. (43) 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. (44) For most investments with identified differences in the commissioning date, NRAs assessed the commissioning date reported in the draft EU TYNDP was an earlier date compared to commissioning date according to the NRAs’ information. In addition, for approximately two third of the investments with different advancement status, NRAs identified the status provided in the draft EU TYNDP was more advanced compared to the status known to the NRA. Particular concerns are raised with regard to

text: PUBLIC

text: Opinion No 04/2021

text: investment 1503 (‘Second HVDC Module IT-ME’) for which the draft EU TYNDP provides status “under construction” instead of “under consideration” as reported by the Italian NRA. This overestimation led to an inclusion of a non-mature investment in the TYNDP reference grid, which is a starting point for the identification of system study needs and the CBA analysis. (45) The Agency concludes that draft EU TYNDP 2020 tends to be too ambitious in terms of the expected commissioning date and the advancement status and reaffirms its recommendation that overly optimistic projections indicated by the project promoters should be avoided by ENTSO-E by defining certain reference project timelines (e.g. number of years from start of permitting to commissioning). For projects with status ‘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. (46) The Agency recommends ENTSO-E to consider the identified differences by NRAs and update the draft EU TYNDP 2020 by taking into account the information and comments provided by NRAs in Annex I, as appropriate. 5. PRACTICAL PROBLEMS IN THE DRAFT EU TYNDP 2020 Numbering of projects and investments (47) Based on the information provided by NRAs, the Agency identified that there are at least 11 transmission investments in the draft EU TYNDP 2020 which were given different investment numbers in comparison to EU TYNDP 2018. These investments are listed in Table 15 in Annex I. (48) Additionally, the Agency identified that in four instances in the draft EU TYNDP 2020, the same project number was assigned to two different projects. These projects are listed in Table 16 in Annex I. (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 processes (e.g. monitoring, project consistency assessment, project data comparison for specific purposes). (50) The Agency recommends ENTSO-E to apply a unique coding for investments and projects in the EU TYNDP, which is consistently applied across the TYNDPs.Error! Reference source not found.

text: (51) The Agency notes that the draft EU TYNDP 2020 project sheets available online at ENTSO-E’s website and in .pdf format only provide investment numbers under the project costs section, which is located at the end of the third online form and at the end of the pdf project sheet. In the Agency’s view the investment numbers in the EU TYNDP project sheets should be displayed in a more prominent way. Clustering of investments (52) The classification of the transmission projects according to the number of investment items included in each project in the draft EU TYNDP 2020 is presented in Table 3. The numbers of transmission investments and projects in the last four TYNDPs are provided in Table 4. Table 3: Classification of transmission projects in the draft EU TYNDP 2020

text: (53) The Agency notes that the average number of investments per project decreased in each EU TYNDP, which is considered a positive sign of increased efforts to avoid over clustering of investments. (54) The criteria for clustering investments are provided in the ‘CBA 3.0 Guideline’ and in the ‘TYNDP 2020 CBA Implementation Guideline’. According to these criteria,

text: Opinion No 04/2021

text: only investments that strongly rely on each other can be clustered together and the clustered investments can be maximum one level of maturity (status) apart from each other. In addition, investments can only be clustered together if an investment contributes to the realisation of the full potential of the main investment. If investments are clustered, the necessity for clustering must also be demonstrated. (55) The Agency notes that projects 170 (‘Baltic States Synchronization with Continental Europe’) and 252 (‘Internal Belgian Backbone Center-East: HTLS upgrade Massenhoven-VanEyck-Gramme-Courcelles-Bruegel-Mercator’) contain investments that are three and two levels of maturity apart, respectively, and should not, according to the above criteria, be clustered under the same project in the draft EU TYNDP 2020. (56) As presented in Table 5, the Agency identified in the draft EU TYNDP 2020 17 projects for which the necessity for clustering is not provided. In addition, for two projects the reasons provided for investment clustering do not sufficiently demonstrate the necessity. Table 5: Projects with clustering issues in the draft EU TYNDP 2020

text: (57) The Agency recommends ENTSO-E to revise the clustering of the investments identified in this section. Investments in the EU TYNDP 2020 should be clustered in line with the ‘CBA 3.0 Guideline’ and the ‘TYNDP 2020 CBA Implementation Guideline’. Investment costs (58) The Agency welcomes that the investment and the annual operating costs are provided for all transmission investments and for all storage projects in the draft EU TYNDP 2020. (59) However, the cost uncertainty remains unreported for 15 % of the transmission investments and for 15 % of the storage projects. (60) The ‘CBA 3.0 Guideline’ stipulate that for mature investments, the costs should be reported together with a clearly explained uncertainty range . For non-mature investments, this principle should also be applied in case detailed project cost information is available . The list of the projects for which uncertainty range is not provided, is included in Table 17 in Annex I, together with the respective advancement status. The Agency notes that 26 (or 50 %) out of the 52 transmission investments and storage projects that have no uncertainty range provided are mature , which means they do not meet the requirements from the ‘CBA 3.0 Guideline’. (61) The Agency recommends ENTSO-E to further improve the cost information by including the cost uncertainty ranges at least for the mature projects in the EU TYNDP 2020. (62) Regarding the reported investment cost (CAPEX), according to the ‘CBA 3.0 Guideline’ , it should be comprised of two parts: “inception CAPEX”, indicator C1a,

text: PUBLIC

text: Opinion No 04/2021

text: which is “the capital cost incurred at inception of the project”, and “sustaining CAPEX”, indicator C1b, which the “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, only an overall number is provided for the CAPEX of each investment item of a project. 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. (63) The project standard costs, presented in ‘TYNDP 2020 CBA Implementation Guideline’ , which are used for reporting CAPEX of less mature projects, are indicated to be based on the ACER Unit Investment Cost report 2015 . However, the data of this report is around 7 years old (mostly covering investments until 2013) and could result in an underestimation of the projects’ total cost and to distorted studies’ results both for the needs identification exercise as well as for these projects benefits. (64) The Agency notes the draft EU TYNDP 2020 provides no information indicating for which projects or investments the standard costs were actually used. In addition, the applicability of the referred ACER Unit Investment Cost report is limited, as it does not provide standard costs for all asset types and for investment types other than new investments (e.g. replacements, upgrades, reinforcements). (65) The Agency recommends ENTSO-E to further improve the transparency of the draft EU TYNDP 2020 project sheets by including information for each transmission investment or storage project on how the costs were determined, i.e. by using standard costs or detailed cost information. In both cases, information on how the cost data was derived should also be provided. Cost-benefit analysis (66) For some projects in the draft EU TYNDP 2020, the section with CBA results indicates that some projects promoters were given an option to opt out of the CBA assessment for their project . (67) The Agency is of the view that CBA should be performed for all projects in the EU TYNDP to meet its objective of ensuring greater transparency regarding the entire electricity transmission network in the Union.

text: Insufficient technical description of investments (68) The Agency’s review of the investments in the draft EU TYNDP 2020 revealed that there are 10 transmission investments which, in the Agency’s view, do not provide a sufficient level of technical information to allow their proper assessment. They are listed in Table 18 in Annex I, together with the Agency’s explanation for insufficient concreteness. (69) The Agency is of the view that for the sake of transparency and robustness of the EU TYNDP, a sufficient level of technical information should be provided for every investment in the EU TYNDP. It recommends ENTSO-E to improve the clarity of the insufficiently concrete investments by providing additional information and technical descriptions in the EU TYNDP 2020. Discrepancies among project sheet formats (70) The Agency notes the draft EU TYNDP 2020 project sheets are available in three formats, i.e. in excel format, in pdf format and online . Excel and pdf formats can be downloaded from the online sheets. (71) The Agency’s comparison of the information and data provided in different formats identified that a different extent of information is provided in the different formats. In particular, while the project sheets in pdf provide the same amount of information as the online sheets, the following information is not provided in the excel sheets: reason for clustering, indication of the main and the supporting investments, information on project inclusion in the reference grid, project promoter, information on whether the project is new or an existing infrastructure is to be updated, links to the respective NDPs, specification of borders for the transfer capacity increase, project level benefits and information on which projects were not subject to a CBA in the EU TYNDP 2020. (72) The Agency invites ENTSO-E to improve the excel project sheets by providing the full extent of information included in the pdf format and online project sheets. (73) In its review of project sheets, the Agency also identified issues regarding data consistency. In particular, the values of the transfer capacity increase in the excel format often differ from the same values provided in the two remaining formats, which raises doubts regarding data credibility. (74) The Agency invites ENTSO-E to ensure that the consistency of the EU TYNDP data is provided across different formats of the EU TYNDP 2020.

text: Additional shortcomings in the draft EU TYNDP 2020 data (75) The Agency notes that there are numerous investments in the draft EU TYNDP 2020 that are reported as “new investments” under “progress of the investment since TYNDP 2018”, although they already appeared in the TYNDP 2018. Reversely, several investment numbers that did not appear in the TYNDP 2018 are not labelled as “new investments” in the TYNDP 2020. In addition, for 10 investments, no information about the progress is reported. (76) The Agency’s review of the draft EU TYNDP 2020 projects revealed additional project-specific inconsistencies: a. Projects 229 (‘GerPol Power Bridge II’) and 350 (‘South Balkan Corridor’) in the draft EU TYNDP 2020 are reported as both cross-border and internal. b. Project 379 (‘Uprate Gatica-Guenes’) is included in the reference grid, although its advancement status is “under consideration”, which means it does not meet criteria for the project inclusion in the reference grid set by the ‘CBA 3.0 Guideline’ . c. Project 170 (‘Baltic States Synchronization with Continental Europe’) includes 10 transmission investments where the element type is not provided. d. The addressed infrastructure needs are not reported for 32 projects in the draft EU TYNDP 2020. e. Different capacity values are provided for the same element in the investment description of transmission investment 373 (‘Ostroleka-Stanislawow’) and in the description of a corresponding project 123 (‘LitPol Link Stage 2’) . f. The information on the transfer capacity increase provided in project sheets for projects 323 (‘Dekani (SI) - Zaule (IT) interconnection’) and 324 (‘Redipuglia (IT) - Vrtojba (SI) interconnection’) is conflicting and the actual capacity increases are not made clear. (77) The Agency recommends ENTSO-E to review the information regarding the investment progress since the EU TYNDP 2018 in the draft EU TYNDP 2020 and adjust where necessary, in order to be consistent. In addition, the Agency invites

text: ENTSO-E to review and eliminate all project-specific inconsistencies reported in this section. HAS ADOPTED THIS OPINION: 1. The Agency finds that the draft EU TYNDP 2020 assessments and the projects included in it generally contribute to the objectives of non-discrimination, effective competition, and secure functioning of the internal electricity market referred to in Article 32(2) of Regulation No 2019/943. 2. However, as pointed out in ACER Opinion 03/2021, the Agency considers that the draft TYNDP 2020 does not sufficiently contribute to the efficient functioning of the 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 2020. 3. Further, in line with

text: the Agency identified a number of inconsistencies between a NDP and the draft EU TYNDP 2020 as provided in the recitals of this Opinion, and recommends ENTSO-E to further enhance 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 the planned projects with cross-border relevance from the NDPs in the EU TYNDP. b. ENTSO-E should ensure that investments included in the EU TYNDP and not included in the NDP of a hosting Member State are 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 in comparison 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 should be avoided by defining certain reference project timelines (e.g. number of years from start of permitting to commissioning). For projects with status ‘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 2020 respect the criteria for clustering, laid down in the ‘CBA 3.0 Guideline’ and in the ‘TYNDP 2020 CBA Implementation Guideline’. ENTSO-E should revise the clustering and demonstrate the necessity for clustering with regard to the draft EU TYNDP 2020 projects identified in section 5.2 of this Opinion.

text: f. ENTSO-E should perform a CBA for all projects in the EU TYNDP . g. The Agency invites ENTSO-E to further improve the costs-related information in the EU TYNDP by: - including the cost uncertainty ranges at least for mature projects; - reporting inception and sustaining CAPEX separately; - 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). h. ENTSO-E should consider the differences between the NDPs and the draft EU TYNDP 2020 identified by NRAs and update the draft EU TYNDP 2020 by taking into account the information and comments provided by NRAs in Table 13 and Table 14 in Annex I, as appropriate. ENTSO-E should also review and eliminate the project-specific inconsistencies in the draft EU TYNDP 2020 reported in section 5.7 of this Opinion. i. ENTSO-E should improve transparency and robustness of the EU TYNDP by ensuring sufficient level of technical information is provided for each investment, including those draft EU TYNDP 2020 investments which are listed in Table 18 of Annex I of this Opinion j. ENTSO-E should ensure the consistency of the EU TYNDP data across different formats of the EU TYNDP. It should also improve the excel project sheets by ensuring they provide the full extent of information as do the pdf format and online project sheets. k. ENTSO-E should apply a unique coding for investments and projects in the EU TYNDP and more prominently display investment numbers in the EU TYNDP pdf format and online project sheets. l. ENTSO-E should, for the purpose of consistency with the previous EU TYNDP, review the information in the draft EU TYNDP 2020 regarding the investment progress since the EU TYNDP 2018 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 it is not yet the case.

CAPEX in the Italian draft NDP 2020 is slightly Costs different (265 million EUR vs. 259 million EUR for the entire cluster in the draft TYNDP 2020). The transfer capacity increase is 400 MW at the Italy North - Italy Center North border and also 150 - 300 Transfer capacities MW at the Italy Center North - Italy Center South. The Update of the TYNDP latter seems not clearly reported in the draft TYNDP 2020.
