text: In this Opinion the part of an EU TYNDP 2018 project which belongs to a national jurisdiction is called “national part of a project”. E.g. if a project 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 one consisting of the part of the interconnector located in country B. The number of relevant national parts of projects is higher than the number of the EU TYNDP 2018 projects as in case of interconnection more than one national part was reviewed. The amount does not include 2 additional cross-border relevant projects which are not included in draft EU TYNDP 2018, but included in the Italian NDP. None of the EU TYNDP 2018 projects is located in Malta and the NRA did not identify any cross-border relevant project.

In Germany, there is no consistency check referring to CBA methodologies so far, but it is under consideration for future NDP. In Italy, the consistency between CBA methodologies is checked via regular updates of the national CBA methodology. Consistency of inputs (unless duly motivated) is a requirement on the TSO.

text: In Lithuania, according to the legal acts the NRA shall assess whether the plan submitted by the TSO is compatible with the actual EU TYNDP. In Slovenia, the NDP is drafted on the basis of the "Rules on the methodology for drafting the development plans of operators and other providers of energy sector activities", which requires compliance in visions/scenarios between the NDP and the EU TYNDP. In Great Britain, the NRA does not require that the methodology be identical to the ENTSO-E CBA methodology - as such small differences in inputs and outputs are expected. However, the NRA asks how the outputs of the NDP methodology compare to the EU TYNDP outputs.

text: For the evaluation of cross-border projects, RAE uses the TYNDP scenarios and respectively the TYNDP CBA (EU-level) results in an indirect manner, given the fact that the investment requests submitted by the project promoters are based on these scenarios. For the assessment of internal projects, for the time being, RAE asks from the Greek TSO an adequate justification of the project's necessity based on the national scenarios, because the adoption of a national CBA methodology in the context of the NDP, consistent with that of ENTSO-E, is still pending. However, especially for the case of islands’ interconnection projects, RAE has established a committee (by virtue of its decision 469/2015) with the purpose of examining if the interconnection of a non-interconnected island with the mainland is beneficial or not. The above committee uses a CBA methodology issued by RAE by virtue of its decision 651/2018. This CBA methodology is based on that of ENTSO-E (using a base case scenario and similar indicators). Then, the Greek TSO can assess the findings of this committee and submit its proposal in the context of the NDP. All four scenarios are used for the determination of needs. A reference scenario is used to assess comparative performance of competing alternatives/options. All four scenarios are used to compare economic performance, and Least Worst Regrets Analysis is used at a minimum. The same requirement is not present for other projects (e.g. reliability, quality of supply, resilience to extreme events).

Scenarios were created in which four basic elements influencing the functioning of the power system were diversified: forecast of demand for electricity and power (2 forecasts), fuel prices (2 forecasts), volume and type of cross-border exchange (2 forecasts), volume and location of new wind sources (2 forecasts). The individual scenarios were created by a combination of the above elements.

text: The NDP was developed to be consistent with the most probable economic scenario and the European energy targets for 2020 regarding energy efficiency, renewable energy and environment. The electrical system analysis performed during the planning process includes three scenarios regarding the GDP growth (upper, central and lower scenario) to cover the potential uncertainties that a forecast may implies. The electrical system analysis is carried out taking into account different scenarios that represent a possible evolution of the main variables that allows to define a specific situation (for example: demand growth, evolution of the power generation mix, fuel prices, etc.). Several planning cases are studied for every scenario. These cases represent the different situations: season (summer/winter); demand hours (peak/flat/valley); year; climatic conditions (wind/sun/water/temperature); dispatch generation; volume of cross-border exchange. The system´s behaviour is studied in a future “N” year taking into account the transmission network state as of 31st December of the year N and modelling the nodal demand from the global demand forecast. The GB scenarios are assessed in the framework of the UK’s 2050 carbon reduction targets set out in the Climate Change Act 2008, which is the UKs contribution to the contribution to the Paris Agreement. Whilst all scenarios show progress towards decarbonisation, only two of the GB scenarios meet the UK’s 2050 target (the “Community renewables” and the “Two degrees” scenarios). The drivers for speed of decarbonisation are policy, economics and consumer attitudes – as such these scenarios are not specifically low, moderate or high GDP growth scenarios. SONI will be shortly consulting on the future scenarios. Following this consultation the final scenarios will be published and reviewed every two years.

The options that the TOs provide are listed and described in the NOA report along with SO alternative options such as operational options. The SO alternative options might include liaison with TOs, distribution licensees or third parties. The NOA and the NOA Methodology describe how the SO assesses the required levels of network transfer requirement, the options available to meet this requirement and the SO’s recommended options for further development.

text: The NOA for interconnectors assesses the optimal level of interconnection for GB consumers. The methodology for delivering this is approved by Ofgem and involves setting a baseline of projects with a threshold of regulatory certainty, and then assessing the NPV of potential (none specific) future interconnection options above that baseline in an iterative optimisation process. This is not, however, a formal CBA for the purpose of assessing the viability of specific projects. Sensitivities are used to enrich the analysis for particular boundaries to ensure that issues, such as the sensitivity of boundary capability to the connection of particular generation projects, are adequately addressed. The SO and TOs use a Joint Planning Committee subgroup as appropriate to coordinate sensitivities. This allows regional variations in generation connections and anticipated demand levels that still meet the scenario objectives to be appropriately considered. Such as masts/basement/wires/cables/substations/protection and control systems. E.g. a new overhead line has to be built in an existing route, and a temporary circuit has to be installed during the construction period. Such as environmental costs avoided, mitigated or compensated under existing legal provisions, cost of planning procedures, and dismantling costs at the end of the life time.

text: No information was provided by the NRA regarding the cost elements. Not specified by the NRA (i.e. The NRA informed that total costs include direct and indirect costs and financial costs. No disaggregation of costs). The forecast cost is a central best view. The TOs and SO agree each year the cost basis to be used for NOA analysis. The information that will have to be agreed includes but is not limited to: price base, that is the financial year of the prices and should be current year prices; annual expenditure profile reflecting the options’ earliest in service dates; any major risks for options costed appropriately; delay costs; the TO’s Weighted Average Cost of Capital (WACC). The TOs provide the individual elements of the investments that provide incremental capability. For consistency of assessment across all options, the TOs provide all relevant cost information in the current price base. The SO reviews the costs that the TOs submit with their options and checks that they are reasonable. This is to help ensure the highest quality data goes into the NOA report process.

For other projects there is no formal CBA methodology applied. For the assessment of projects with cross-border impact, the results of the latest EU-TYNDP are used, including imports and exports data. Particularly, the reports of Regional Investment Plan (Continental South-East) are used, which are based on the Pan-European market study results combined with European and/or regional network studies. Furthermore, the TYNDP 2018 Regional Insight Report for the North-South Interconnections East is considered. Additional studies include: harmonic, insulation co-ordination, transient and small signal stability. The range of studies depends on the technology and case being studied.

text: Multiple models, as needed (e.g. national model to study local developments, multi-national model for transfer capacity calculations). Synchronisation studies, adequacy studies, studies on integration of offshore wind power plants. Cross-border flows have been determined on the basis of analyses of the EU market model. In the next step, a market model is used with the full national transmission network model and designated cross-border flows. The analysis carried out with such a model allows to identify bottlenecks and propose investments eliminating them, taking into account the greatest effects for the power system. For cross-border relevant projects the EU TYNDP results are used. For the time horizons not covered in TYNDP and the related PEMMDB, specific (detailed, unit-by-unit based) market studies are carried-out at national level, with the appropriate assumptions on the exchanges. The SO uses the scenarios and the criteria stated in the NETS SQSS to produce the future transmission capability requirements by using an in-house tool called ‘Peak Y’. The SO then passes these capability requirements to the TOs to identify future transmission options. In response to the data on boundary capabilities and requirements, TOs identify and develop multiple credible options that deliver the potentially required boundary capabilities. The SO then undertakes the cost-benefit analysis studies on these options. Not specified.

text: Article 8(11)

text: thereof,

text: Whereas:

text: 1. INTRODUCTION

text: Article 8(11) of Regulation (EC) No 714/2009

text: tasks the Agency for the Cooperation of Energy Regulators (‘the Agency’) with providing an opinion on the national ten-year network development plans (‘the NDPs’), to assess their consistency with the EU-wide ten-year network development plan (‘the EU TYNDP’). (2) If the Agency identifies inconsistencies between a NDP and the EU TYNDP, it shall recommend amending the NDP or the EU TYNDP as appropriate. If such NDP is elaborated in accordance with

text: Article 22 of Directive 2009/72/EC

text: of the European Parliament and of the Council, the Agency shall recommend that the competent national regulatory authority (‘NRA’) amend the NDP in accordance with Article 22(7) of that Directive and inform the Commission thereof.

text: (3) NRAs have provided the Agency with essential information on the general regulatory framework, inputs, outputs and methodologies used for the development of the NDPs, as well as specific information on the latest draft or final NDP.

text: (4) Further, NRAs have provided the Agency with information on the draft EU TYNDP 2018 projects and corresponding investments which are located in their jurisdictions and on those investments which appear on their NDPs, have a cross-border relevance, but do not appear in the draft EU TYNDP 2018. The data collection from NRAs was completed on 29 April 2019.

text: 2. DEFINITIONS AND SCOPE

text: (5) Similar to the Agency’s previous practice, the Agency considers as ‘national ten-year network development plans’ pursuant to

text: all relevant network planning instruments, even if they are referred to with a different title (e.g. investment plan) and a different time span.

text: (6) Further, for the purpose of this Opinion the Agency considered the following definitions:

text: (a) Cost benefit analysis (CBA): Conceptual framework applied to any systematic, quantitative appraisal of a public or private project to determine whether, or to what extent, that project is worthwhile from a social perspective.

text: (b) Infrastructure / investment need: Investment gaps which indicate a need for further development of the transmission system, e.g. a need to develop capacity across a boundary.

text: (c) Market study: Market studies are used to calculate the optimal dispatch of generation units. Besides the dispatch of generation and demand (if modelled endogenously), market simulations compute the market exchanges between bidding areas and the corresponding marginal costs for every modelled time step. Market studies results allow the computation of some of the CBA indicators, such as socioeconomic welfare (SEW), CO2 emissions, RES integration and the adequacy component of security of supply .

text: (d) Network study: Network studies are based on a detailed representation of the transmission network and are used to calculate the actual power flows that take place in the network under given generation/load/market exchange conditions. Network studies allow to identify bottlenecks in the grid, highlighted by the power

text: flows resulting from the market exchanges. Network studies results allow the computation of some of the CBA indicators such as: Net Transfer Capacity (NTC), grid losses and the stability component of the security of supply .

text: (e) Scenarios: A set of assumptions for modelling purposes related to a possible future situation in which certain conditions regarding demand and installed generation capacity, infrastructures, fuel prices and global context occur .

text: (f) Progress of a project: It indicates whether a project’s implementation is on track compared to its plan. A project is ‘on time’ if the commissioning date is unchanged compared to the commissioning date in the plan. A project whose implementation is sped up and for which therefore the expected commissioning date is now earlier than previously considered is ‘ahead of schedule’. A project, which falls behind its schedule is either ‘delayed’ or ‘rescheduled’, or both .

text: (g) Smart grid projects: ‘Smart grid’ means an electricity network that can integrate in a cost efficient manner the behaviour and actions of all users connected to it, including generators, consumers and those that both generate and consume, in order to ensure an economically efficient and sustainable power system with low losses and high levels of quality, security of supply and safety .

text: (7) The Opinion aims to review the NDPs of all the jurisdictions of EU Member States (Northern Ireland and Great Britain as separate jurisdictions) and of those countries, which participate in the Agency’s working structures on a voluntary basis, i.e. Norway, Switzerland and Montenegro, and to assess their consistency with the EU TYNDP.

text: 3. PROCEDURE

text: (8) On 14 January 2019, the Agency invited the NRAs from the 32 aforementioned jurisdictions within the targeted scope of the Opinion to review their relevant NDPs and assess their consistency vis-à-vis the draft EU TYNDP 2018.

text: (9) By 29 April 2019, 29 NRAs provided input to the Agency via an online data collection tool (EU Survey) and/or by email on the relevant NDP (see Table 16) and/or national parts of projects . The list of NDPs on which the Agency has received information from the NRAs and the number and rate of reviewed national parts per jurisdiction is presented in Table 1.

text: Table 1. List of assessed NDPs and number and rate of reviewed national parts of projects

text: 4. ASSESSMENT OF THE NDPS AND THE EU TYNDP 2018

text: General notes

text: (10) In the Agency’s view, the assessment of consistency of the NDPs with the EU TYNDP may cover in principle three fundamental aspects:

text: (a) Consistency of inputs (including scenario building);

text: (b) Consistency of analytical methodology (including identification of needs, CBA);

text: (c) Consistency of outputs (including list of projects).

text: (11) Based on NRAs review of their NDPs and on the Agency’s assessment of the draft EU TYNDP 2018 , the Agency concludes on major patterns, substantial differences and inconsistencies between the NDPs and the EU TYNDP (and the corresponding investments). The Agency stresses that not all differences constitute inconsistencies, as some differences may enrich the infrastructure planning (e.g. use of additional scenarios, sensitivities, more detailed modelling) or may arise from the development of the projects

text: over time (i.e. different timing of the plans). The Agency also identifies best practices for the development of the NDPs and the EU TYNDP and recommends that NRAs and/or other relevant national entities responsible for the elaboration and approval of the NDP follow them.

text: (12) The Agency positively notes that the vast majority of NRAs already (individually) assess the consistency of the NPDs in their jurisdictions with the EU TYNDP with respect to one or more of the three fundamental aspects referred to in recital (10) above : 2 NRAs (BE and PT) assess the consistency on all three aspects, 12 NRAs assess the consistency of inputs and outputs, 1 NRA assesses the analytical methodology and the outputs, 7 NRAs assess the consistency of the inputs only and 2 NRAs the consistency of the outputs only. 5 NRAs (CY, DK, EE, NO and RO) do not carry out individual consistency check on any of the three aspects. For more details please refer to Table 2.

text: Table 2. NRAs consistency check with EU TYNDP for the development of NDPs

text: Assessment of the NDPs

text: 4.2.1. Consistency of the general regulatory frameworks for the development of the EU TYNDP and the NDPs

text: (13) The Agency examined the NRAs’ information on unbundling models chosen for the electricity TSOs, as the Independent Transmission System Operators (‘ITOs’) model, according to Chapter V of Directive

text: requires stronger regulatory oversight, including review, consultation and monitoring of the NDPs compared to the Independent System Operator model (‘ISO’) according to Article 13 of the same Directive or the full ownership unbundling (‘OU’) model.

text: (14) Table 3 shows the different unbundling models for TSOs applied in the different jurisdictions, as well as the frequency with which NDPs are provided. The Agency notes that full ownership unbundling is applied in approximately half of the NRAs’ jurisdictions (15 out of 29), while the ITO model is applied in 7 jurisdictions (24%). The remaining (non-derogated) jurisdictions apply multiple models or the ISO model.

text: Pursuant to

text: Article 44 of Directive 2009/72/EC

text: , 3 Member States (CY, LU, MT) are derogated from the application of the unbundling requirement. In addition, Ireland has a similar derogation .

text: Table 3. Unbundling models and frequency of plans

text: 4.2.1.1. Frequency of development of the plans

text: Article 8(10) of Regulation (EC) No 714/2009

text: requires the European Network of Transmission System Operators for Electricity (‘ENTSO-E’) to adopt and publish an EU TYNDP every two year.

text: (16) Pursuant to

text: Article 22 of Directive 2009/72/EC

text: , TSOs certified under the ITO unbundling model shall prepare a NDP every year.

text: Article 37(3)

text: (c) of the same Directive (indirectly) requires that ISOs also present a multi-annual NDP every year. TSOs under ownership unbundling models have no such legal obligations.

text: (17) The Agency finds that in approximately half of the jurisdictions (15 out of 29), the NDP is developed every year, in 11 jurisdictions every 2 years, and in the remaining 3 jurisdictions the NDP is developed less frequently (i.e. every 3, 4 or 6 years respectively).

text: (18) The Agency notes that NDPs which are elaborated every year appear to be slightly more exposed to complexities in fulfilling the legal deadline for the development of the NDP, which confirms previous findings of the Agency .

text: (19) While the Agency did not find a clear correlation between the date of the latest NDP and the number of identified differences, it is reasonable to assume that, as the projects develop over time, a lower frequency of development of NDPs increases the risk that

text: information provided in the NDPs become obsolete and differences occur between the NDP and the EU TYNDP, which may also result in later inconsistencies.

text: (20) Therefore the Agency recalls the importance of keeping the NDPs up to date. However, in order to avoid delays in the timely approval of the NDPs, the Agency reiterates its previous recommendation (see Agency’s Opinion No 08/2014, p.6) that NDPs are ideally prepared with a biennial frequency and be accompanied by a monitoring update in the years in between.

text: (21) The Agency notes that this recommendation is in line with the Commission’s proposals within the ‘Clean Energy Package’ which also foresees an ‘at least every two year’ frequency, instead of every year , and that some NDPs’ (CZ, DE, SK) frequency has already changed from annual to biennial, compared to the information provided in 2016 .

text: 4.2.1.2. Project inclusion

text: (22) Pursuant to

text: Article 8(10)

text: (a) of

text: Regulation (EC) No 714/2009

text: , ENTSO-E shall develop a ten-year plan which is built on the NDPs. ENTSO-E shall ensure that the EU TYNDP does not discriminate between TSOs and third party project promoters.

text: Article 22(2) of Directive 2009/72/EC

text: provides a ten-year scope for the NDPs of TSOs certified under the ITO unbundling model (i.e. the NDPs shall indicate to market participants the main transmission infrastructures that need to be built or upgraded over the next 10 years, contain all the investments already decided and identify new investments which have to be executed in the next three years). The Agency notes that projects of common interests (‘PCIs’), including those which may be promoted by third parties shall also become an integral part of the relevant NDPs pursuant to

text: Article 3(6) of Regulation (EU) No 347/2013

text: (24) The Agency notes that the draft EU TYNDP 2018’s time horizon is indeed more than 10 years and includes investments with an expected commissioning date beyond 2030 and/or those which are still in study phase or under consideration (see Agency’s Opinion No 11/2019, p.5). The draft EU TYNDP 2018 includes and assesses third-party transmission projects and also storage projects.

text: (25) The Agency notes that NDPs only slightly vary in terms of the time horizon up to which the projects included in them are planned. The vast majority of the NDPs include projects which are expected to be commissioned in the next 10 years . Three NDPs (EE, DE, NO) have an even longer (i.e. 15-20 years) time horizon .

text: (26) In 23 jurisdictions out of 29 (79%), the NDPs include (in general) projects ‘under consideration’ (e.g. studies, projects conditional to specific circumstances). In 4 jurisdictions (CY, LU, GB, NL) they are provided separately from the NDP and in the remaining 2 jurisdictions (FR and BG) they are not provided either in the NDP or separately.

text: (27) As shown in Table 4, the Agency notes that, beyond the transmission projects, 12 NDPs include (or allow to include) SCADAs, ICT, cybersecurity and/or communication infrastructures, 7 NDPs include smart grid projects and 6 NDPs include storage projects.

text: 1 NDP (HU) also includes distribution grid projects at 132 kV voltage level.

text: Table 4. Categories of projects included in the NDPs

text: (28) As shown in Table 5, in 13 jurisdictions, the relevant third-party projects are included or referred to in the NDPs: In some instances they are assessed together with the national TSO’s projects, in the others they are described or only listed, but not subject the same assessment (e.g. CBA). In 5 jurisdictions third-party projects are allowed to be included, but no application has been made yet. In the remaining 11 jurisdictions, third-party projects are not allowed to enter the NDP.

text: (29) The Agency positively notes the increase in the number of NDPs which include or refer to third-party projects, compared to 2016 (i.e. 5 NDPs ).

text: Table 5. Inclusion of third-party projects in the NDPs

text: (30) In line with its considerations in its Opinion No 08/2017 (p.4-5), the Agency recommends that network planning documents include/inform on studies and projects ‘under consideration’, even if they may go beyond the time horizon of the NDP and clearly flag them as such . The Agency is of the view that TSOs’ projects, which are not included (or approved, where applicable) in the NDPs, should be considered as projects ‘under consideration' by default.

text: (31) The EU TYNDP and ideally also the NDPs should have separate project Appendices: one listing the mid-term and long term (i.e. already ‘planned’ and expected within 10 years) projects and the other listing ‘future’ projects or studies (i.e. ‘under consideration’ or planned only beyond 10 years). Such a clear separation provides increased transparency with regard to the different levels of uncertainties associated with these two ‘categories of projects’.

text: (32) The Agency is of the view that the NDPs cannot provide the proper basis for the EU TYNDP regarding the inclusion (and exclusion) of third-party projects, where such projects are not allowed to enter the NDP. The Agency therefore recommends to expand the scope of the NDPs to allow the inclusion of third-party projects.

text: 4.2.1.3. Consultation

text: (33) In line with

text: Article 10(1) of Regulation (EC) No 714/2009

text: , while preparing the draft EU TYNDP, ENTSO-E shall conduct an extensive consultation process, at an early stage and in an open and transparent manner, involving all relevant market participants, and, in particular, the organisations representing all stakeholders. The consultation shall also involve NRAs and other national authorities, supply and generation undertakings, system users, including customers, distribution system operators (DSOs), relevant industry associations, technical bodies and stakeholder platforms. It shall aim at identifying the views and proposals of all relevant parties during the decision-making process.

text: Article 6(3) of Regulation (EC) No 713/2009

text: also stipulates that the draft EU TYNDP shall be submitted to the Agency for an opinion. The Agency’s opinion is not binding to ENTSO-E, but the Agency expects that it is duly taken into account by ENTSO-E before the finalisation of the EU TYNDP.

text: (35) Regarding the elaboration of the draft EU TYNDP 2018, the Agency already reviewed the stakeholder involvement and concluded that ENTSO-E carried out an extensive consultation process .

text: (36) Pursuant to

text: Article 22 of Directive 2009/72/EC

text: , TSOs certified under the ITO model shall submit to the NRA their NDP after having consulted all the relevant stakeholders. The NRA shall also consult all actual or potential system users on the NDP in an open and transparent manner. The NRA shall publish the result of the consultation process, in particular possible needs for investments.

text: (37) As shown in Table 6, stakeholder consultations are part of the development process of most NDPs. However, the party responsible for the public consultation (i.e. the TSO or the NRA) and the level of involvement of stakeholders vary across jurisdictions. In 20 out of 29 jurisdictions (69%), the draft NDP is subject to public consultation (i.e. any stakeholder is invited to participate), some of them held additional separate consultation on the scenarios and/or the relevant analytical methodology. In 2 jurisdictions (LU, GB), only the scenario development part of the NDP is consulted, in 1 jurisdiction (DK) in addition to the scenarios also the large projects are consulted. In 4 jurisdictions, no public consultation is carried out, but the TSO has specific (bilateral) consultations at least with the NRA (CY, NL), or also with other stakeholders (HU, SI). In 2 jurisdictions (EE, SE), neither public consultation nor any specific or bilateral consultation is carried out.

text: Table 6. Consultations with regard to the development of the NDPs

text: (38) The Agency considers it of utmost importance that stakeholders are appropriately involved in the EU TYNDP and the NDP building process in order to increase its quality and public acceptance. In this regard, in its Opinion No 11/2019, the Agency already called on ENTSO-E better and more transparently to explain how the public consultation results are taken into account.

text: (39) Further, the Agency recommends that a public consultation be carried out in each jurisdiction on the draft NDP irrespective of the chosen unbundling model. In more advanced national frameworks, separate consultations on the major building blocks of the NDPs (e.g. scenario development, CBA methodology) should also be considered in order to ensure that stakeholder inputs are timely taken into account (i.e. before the assessment of the projects). The results of the public consultations should be published and information on the treatment of the stakeholder comments provided.

text: 4.2.1.4. Approval of the NDPs and the NRA’s respective role

text: (40) The regulatory oversight of the EU TYNDP is mainly carried out through non-binding opinions of the Agency, while, in most jurisdictions, NRAs are formally empowered to approve, reject and/or validate the NDP proposals of the TSOs. As shown in Table 7, in

text: 20 out of 29 jurisdictions, there is a public entity (i.e. the NRA in 14 jurisdictions, the Ministry in 5 jurisdictions and a 2-round procedure by the Ministry and the NRA in 1 jurisdiction) approving the draft NDP prepared by the TSO. Out of the remaining 9 jurisdictions, in 3 there is a binding opinion of the NRA, in 3 there is at least some scrutiny of the NRA (via a non-binding opinion or request to amend the NDP), while in

text: 3 of them (EE, LU, SE) the NDP is not approved by any public entity and the NRA plays only a limited consultative role in the NDP elaboration process without any effective power.

text: Table 7. Approval of the NDP and NRAs’ respective roles

text: (41) The Agency notes that the legal requirements for the regulatory oversight is generally higher for NDPs than that for the EU TYNDP as in 79% of the jurisdictions, the TSO is bound by the approval or the opinion of an entity acting in the public interest (i.e. NRA or Ministry/ies, or both).

text: (42) In this regard, the Agency is of the view that the regulatory oversight over the elaboration of the EU TYNDP should be strengthened, e.g. by giving a binding nature to the Agency’s opinion.

text: (43) Similarly, irrespective of the unbundling model chosen for the TSO(s), in each jurisdiction the NDP should be subject to appropriate regulatory oversight. Therefore, the Agency recommends to strengthen NRAs’ or other public entities’ role regarding the development of the NDPs in those jurisdictions where the TSO currently adopts the NDP without any regulatory approval or binding scrutiny.

text: (44) Further, the Agency recommends that all formal acts on the NDPs, where applicable, (i.e. decisions, opinion, consistency analysis, monitoring) be published.

text: 4.2.2. Consistency of inputs and methodologies

text: (45) Pursuant to

text: , the EU TYNDP shall include, among other features, scenario development, and it shall identify investment gaps, notably with respect to cross-border capacities.

text: (46) Pursuant to

text: Article 11(1) of Regulation (EU) No 347/2013

text: , ENTSO-E shall apply a harmonised energy system-wide cost-benefit analysis (CBA) at Union level, including on network and market modelling, for the preparation of each EU TYNDP.

text: (47) Regarding the study horizon of scenario development, the CBA methodology provides that the common input data set shall cover years n+5, n+10, n+15 and n+20, where n is the year in which the analysis is performed.

text: (48) Pursuant to

text: Article 22(3) of Directive 2009/72/EC

text: , TSOs certified under the ITO unbundling model should make reasonable assumptions about the evolution of generation, supply, consumption and exchanges with other countries, taking into account investment plans for regional and EU-wide networks for the purpose of the NDP.

text: 4.2.2.1. Scenarios

text: (49) The EU TYNDP 2018 scenarios are described in the ENTSOs’ scenario development report . ENTSO-E studies one (short term) best estimate scenario for year 2025 and three (long term) scenarios for year 2030. Two out of the three long term scenarios feature ‘high economic growth’, while one considers a ‘moderate [i.e. average] growth’.

text: (50) The EU TYNDP 2018 assesses and provides the projects’ benefits for each of the aforementioned scenarios. The Agency’s views on these scenarios were provided in its Opinion No 10/2018 on the ENTSOs’ draft TYNDP 2018 scenario report. In that Opinion the Agency observed that, in particular for the ‘short-term’ study year (i.e. 2025), a sensitivity analysis (except with respect to climate years) was missing and, for the

text: ‘mid/long-term’ study year (i.e. 2030), ENTSOs failed to consider a wide spectrum of possible futures, which would have increased the robustness of the assessment.

text: (51) The reviewed NDPs display a large variety of approaches in defining the future energy landscape. The Agency notes that all but three of the 26 NDPs (88%), for which this information is available, use multiple scenarios approach (or at least consider different combination of values for certain parameters) and, in most cases, assess the projects against several or all of these scenarios to decide on their necessity, which is a very significant change compared to the findings in 2016 . More than one third of the NDPs appear to also use a scenario which considers lower economic growth or demand. About two thirds of the NDPs include multiple study years for which the assessment is carried out. Most of the NDPs include a study horizons up to the year n+15, but 8 NDPs also assess the projects in a study horizon beyond 15 years. The details on the use of scenarios in each jurisdiction are presented in Table 8.

text: Table 8. Scenarios used in the latest NDPs

text: (52) Further, the Agency notes that the vast majority (i.e. 79%) of the NDPs reflect on the EU TYNDP scenarios: out of 29 jurisdictions, 8 (27%) use both EU and national scenarios,

text: 14 (48%) use only national scenarios, but take EU TYNDP scenarios into account and 1 (4%) use only EU scenarios. However, the Agency also notes that in 6 NDPs the EU TYNDP scenarios are not (or only potentially) taken into account.

text: (53) The Agency notes that scenarios developed for the NDPs take into account demand, generation and cross-border capacities basically in all jurisdictions, while other elements, including forecasts for demand response, use of heat pumps, electric vehicles and new storage facilities are remarkably less frequently, but still considered in about half of the jurisdictions, as shown in Table 9.

text: Table 9. Elements taken in account for the construction of scenarios in the NDPs:

text: (54) The way in which scenarios are developed and used is critical in terms of the assessment of a project, as the need for the project and the accompanying costs and benefits strongly depends on the chosen parameters. As pointed out in the Agency’s Opinion No 11/2019 (p.25), the project-specific CBA results in the EU TYNDP 2018 show important differences compared to those in the EU TYNDP 2016, which (as explained by ENTSO- E) were partially due to the new scenarios considered for the analysis.

text: (55) The Agency considers the ‘best estimate’ approach for the short term and the multiscenario approach for the long term as appropriate, so as better to consider the growing uncertainties over time and better to assess the resilience of the investment projects against them.

text: (56) The Agency also recommends to complement the near-term best-estimate scenario with appropriate sensitivity analyses. Such sensitivity analysis would be particularly useful in detecting the main factors on which a project outputs (benefits) depends.

text: (57) As regards the long term, the Agency deems that the fundamental objective of the scenarios is to depict an appropriate range of plausible futures. In this regard, the Agency reaffirms its view that considering a ‘low economic growth’/‘slow progress’ scenario could help to build trust in the scenario development, by not just building on policy goals, but also highlighting possible risks of not achieving these goals. Therefore, a ‘slow progress’ scenario should be investigated by the CBA, for all years where multiple scenarios are developed in the EU TYNDP.

text: (58) As regards the scenario-building method, the Agency recommends to develop at least one robust scenario with a top-down approach (i.e. consistent and coherent assumptions across Europe), which takes into account country specifics. This(ese) scenario(s) should be evaluated in the EU TYNDP and taken into account to construct the NDPs’ scenarios.

text: (59) When study years are used (instead of continuous description assessing each future year), the Agency considers it as a good practice that NDP scenarios and CBA assessments primarily refer to the rounded years (i.e. years ending with 0 and 5).

text: 4.2.2.2. Infrastructure needs

text: (60) For the purpose of the EU TYNDP 2018, ENTSO-E released a report which aimed to depict infrastructure needs in 2040 . The Agency’s main considerations regarding the assessment of the infrastructure needs were provided in its Opinion No 11/2019 (p.14).

text: (61) Based on the NRA responses, as shown in Table 10, the Agency identified that for most NDPs (62%), the TSO does not conduct a formal (i.e. based on an approved methodology) infrastructure gap (needs) identification process, before projects are proposed; instead projects are defined based on the TSO’s experience and knowledge of the transmission system and their assessed benefits.

text: Table 10. Methodology used for the identification of infrastructure gaps (needs)

text: 4.2.2.3. Methodologies used for the assessment of the projects

text: (62) In the draft EU TYNDP 2018, the projects are assessed using the ENTSO-E CBA methodology 2.0 approved by the European Commission on 27 September 2018 . The Agency’s view on the CBA methodology was already provided in its Opinion No 05/2017.

text: (63) The CBA methodology identifies two cost categories: investment costs (CAPEX) and operating expenditure (OPEX). According to their definitions, the CAPEX of the investments in the EU TYNDP 2018 should include the following cost elements (p.42):

text: (a) Expected costs for permits, feasibility studies, design and land acquisition;

text: (b) Expected cost for equipment, materials and execution costs (such as towers, foundations, conductors, substations, protection and control systems);

text: (c) Expected costs for temporary solutions which are necessary to realise a project (e.g. a new overhead line has to be built in an existing route, and a temporary circuit has to be installed during the construction period);

text: (d) Expected environmental and consenting costs (such as environmental costs avoided, mitigated or compensated under existing legal provisions, cost of planning procedures);

text: (e) Expected costs for devices that have to be replaced within the given period (consideration of project life-cycle); and

text: (f) Dismantling costs at the end of the equipment life-cycle.

text: (64) The OPEX figures in the EU TYNDP 2018 consists of the expected annual maintenance costs and the expected annual operation costs, reported as an annual average figure.

text: (65) The ENTSO-E CBA methodology includes eight (partially overlapping) benefit categories (i.e. SEW, CO2 variation, RES integration, societal well-being, grid losses, adequacy, flexibility and stability) and three residual impact categories (environmental, social, other). Beyond these, the EU TYNDP 2018 includes a so called ‘missing benefit’ or ‘declared values’ category, which allows the project promoters to report on benefits, which are either not captured by the CBA methodology or captured, but not adequately calculated in the EU TYNDP 2018.

text: (66) The projects, which were part of the reference (or ‘baseline’) network (for a certain study year), were assessed with the Take Out One at the Time (TOOT) methodology, the other (non-reference grid) projects were assessed with the Put IN one at the Time (PINT) methodology. For competing projects, ENTSO-E also used the multiple TOOT approach.

text: (67) Regarding the NDPs, as shown in Table 11, the way with which projects are assessed greatly varies across jurisdictions, but the use of the CBA has increased compared to the practice in 2016 . In 17 out of 29 jurisdictions (58%), a formal (e.g. based on a methodology approved by law or a public entity) CBA is carried out, in most of them only for some of the proposed projects (e.g. cross-border or high CAPEX projects). In the remaining jurisdictions the projects are selected according to the planning criteria set by the TSOs and in one instance the way how the projects are assessed was not specified. The Agency notes that the share of NDPs building on a formal CBA analysis is expected further to increase in the future (e.g. in GR).

text: Table 11. Methodology used for the assessment of the projects in the NDPs

text: (68) Regarding the costs, the Agency notes that the expected cost for materials and assembly and the expected costs for temporary solutions, which are necessary to realise a project, are included in the costs figures used for most of the NDPs, as shown in Table 12. However, not all cost elements identified by the CBA methodology are considered in many of the jurisdictions.

text: Table 12. Cost elements included in the total project expenditures available in the NDP or to the NRA

text: (69) Noting the different cost elements included in the total expenditure of the projects in the different jurisdictions, the Agency considers it important to clarify in the relevant NDPs, which cost elements the provided cost figures correspond to.

text: (70) The Agency notes that in those jurisdictions where a CBA is carried out, multiple benefits are considered, as shown in Table 13. The Agency notes that even in those jurisdictions where no CBA is carried out for the NDP, some aspects (e.g. contribution of the project to security of supply or adequacy) are quantitatively assessed.

text: Table 13. Benefit categories and their monetisation in the NDPs

text: (71) The CBA or other project assessments are carried out via different market, network and/or dynamic studies. As shown in Table 14, in about two third of the jurisdictions both market and network studies are used, in 1 jurisdiction (CY) only a specific market is used, in 8 jurisdictions only network studies are carried out. Most of the indicated studies use models covering the relevant region or beyond (i.e. EU level). Only few studies are carried out using only national assumptions.

text: Table 14. Studies carried out in the NDPs

text: (72) The Agency recalls its recommendation in its Opinion No 04/2016 (p.3) that the NDPs should include market studies for projects of cross-border relevance and use the multi-

text: national network models fully to assess the project’s influence on the interconnected network.

text: (73) The Agency is of the view that the CBA, which allows the comparison of the costs and benefits of a project, is a good practice and carrying out a CBA should be considered in each jurisdiction at least for the larger projects, as it promotes transparency and objectivity in the decision on the projects. In this regard, the Agency recalls the importance of avoiding double-counting of the benefits.

text: 4.2.2.4. Discounting parameters used

text: (74) As described in ENTSO-E CBA methodology (p.24), in order to calculate the Net Present Value (NPV) of a project, its monetised costs and benefits must first be estimated using the same assumptions and then discounted such that those costs and benefits are all actualised to the year in which the study is performed). Discounted costs (negatives) and benefits (positives) can then be added in order to calculate the NPV of the project.

text: (75) In line with the Agency’s Opinion , the following discounting parameters should be applied in the EU TYNDP:

text: (a) 25 years of operation;

text: (b) residual value equal to 0;

text: (c) 4% (real) discount rate.

text: (76) Further, the ENTSO-E CBA 2.0 (p.14) provides that the mid-term horizon scenarios have to be representative of at least two study years and that (p.24) the benefits should be aggregated across years as follows:

text: - for years from the year of commissioning (i.e. the start of benefits) to the first midterm time horizon: the first mid-term year’s benefits are extended backwards;

text: - for years between different mid-term, long-term and very long-term time horizons (if any): benefits between the time horizons are linearly interpolated;

text: - for years beyond the farthest time horizon: benefits are maintained at the same level of this farthest time horizon.

text: (77) The Agency notes that these discounting rules are broadly applied for the NDPs as well. As shown in Table 15, out of the 17 NDPs for which a CBA assessment is carried out:

text: - in 14 NDPs (82%), all costs and benefits are discounted to the same year in 10;

text: - in 8 NDPs (47%), 25 years of operation are assumed;

text: - in 8 NDPs (47%), a 4% (real) discount rate is applied; and

text: - in 7 NDPs (41%), a 0 residual value is assumed.

text: Table 15. Application of the EU TYNDP 2018 discounting parameters in the jurisdictions with a formal CBA methodology

text: 4.2.3. Publication

text: (78) Pursuant to

text: , ENTSO-E shall adopt and publish the final EU TYNDP. Since the EU TYNDP is subject to public consultation, the draft plan is also publicly available.

text: (79) Regarding the NDPs, the Agency notes that in all, but 2 jurisdictions (CY, LU), the NDP is published. (In 16 jurisdictions both the draft and the final NDP are published, while in

text: 11 jurisdictions only the final NDP is published). Table 16 presents the list of the latest NDPs and the links to them.

text: Table 16. Latest NDPs and links to them

text: (80) The Agency considers that the public availability of the draft and final NDPs contributes to transparency and thus consistency of the NDPs vis-à-vis each other and vis-à-vis the EU TYNDP, as well as to the efficient infrastructure planning and implementation in Europe. Therefore the Agency recommends that the draft and final NDPs are published in all jurisdictions.

text: 4.2.4. Transparency of the information

text: (81) The draft EU TYNDP 2018 mostly includes the following project specific information :

text: (a) The expected commissioning date for each investment;

text: (b) The status for each investment;

text: (c) Transfer capacity increase;

text: (d) Investment costs (CAPEX) for each investment;

text: (e) The annual average OPEX for each investment;

text: (f) Benefits.

text: (82) In addition, the draft EU TYNDP 2018 provides information about the evolution of the investment since the previous EU TYNDP.

text: (83) Information about the availability of project data in the NDPs was provided for 28 NDPs . The Agency notes that the status and the commissioning date are the most frequently publicly available information items: The commissioning date is available in 19 NDPs; the project status is available in 18 NDPs. In the remaining instances, the status information is available to the NRA only.

text: (84) The availability of other project or investment specific information (including costs, benefit and transfer capacity increase) is more limited.

text: (a) Investment cost information is publicly available in 13 jurisdictions (in two jurisdictions, in a separate document not in the NDP and in another one only for the most important projects) and in 14 jurisdictions available only to the NRA. In one jurisdiction (FI), the investment costs are not available to the NRA.

text: (b) Life cycle cost (or OPEX) information is publicly available in only 4 jurisdictions (in one jurisdiction in a separate document not in the NDP and in another one only for the most important projects) and in 15 jurisdictions available only to the NRA or the relevant competent authority. In 6 jurisdictions, the life cycle costs are not available to the NRA or the relevant competent authority. In the 3 remaining instances, the NRA did not provide information on the availability of this specific project data.

text: (c) Monetised benefits are provided in 7 NDPs and non-monetised benefits in additional 6 NDPs. In 8 jurisdiction the benefits are available to the NRA but not published, in 6 jurisdictions, no benefit data is provided to the NRA (or the competent authority), either in monetised or non-monetised form and in one instance, the NRA did not provide information on the availability of this specific project data.

text: (d) Expected increase of transfer capacity for each project is included in the public NDP in 13 jurisdictions, in additional 10 jurisdictions this information is provided only to the NRA or the competent authority, while in 4 jurisdictions it

text: is not available to them at all. In one instance, the NRA did not provide information on the availability of this specific project data.

text: (85) The Agency notes that only in one jurisdiction information on the progress of the projects and reason for their delay or rescheduling is not provided either publicly or to the NRA. In about half of the jurisdictions, the monitoring results are provided either in the NDP or in a separate publicly available document and in about half of them it is available only to the NRA. In one instance, the NRA did not provide information on the availability of this specific project data.

text: (86) The information published in the NDPs and/or available to the NRAs is shown in Table 17.

text: Table 17. Project specific elements included in the NDPs

text: (87) In its Opinion No 04/2016 (p.7), on the consistency of the NDPs with the EU TYNDP, the Agency already pointed out that the NDPs do not always provide the same set of information and insisted on the need for NDPs to contain the fundamental project information (full information on commissioning dates, project status, increase of transfer capacity and project cost). The Agency reiterates its recommendation that such fundamental information should be published in the NDPs.

text: (88) In order to enhance transparency and allow a better interaction between the EU TYNDP and NDPs, the Agency recommends that not only the EU TYNDP include a mapping of cross-references between the investment codes in different plans , but also NDPs use, beyond the national coding systems, cross-referencing with EU TYNDP coding.

text: Assessment of the projects in the NDPs and EU TYNDP

text: 4.3.1. Inclusion in NDPs

text: (89) The NRAs reviewed 239 national parts of transmission projects and 20 storage projects, when carrying out the consistency check of the projects included in the draft EU TYNDP 2018.

text: (90) Out of 239 national parts of transmission projects, the NRAs identified 185 national parts (77%) which are fully included in the NDPs (i.e. all those investments, of the project which are located in the territory of a jurisdiction are included in the relevant NDP). 6 national parts (3%) which are only partially included (i.e. not all of the investments located in the territory of a jurisdiction is included) and 47 national parts (20%) which are not included in the relevant NDPs. Out of the 20 storage projects, 5 are included in the relevant NDPs. The list of projects not included or partially included in one or more of the relevant NDPs is provided in Tables 19-21 in Annex I.

text: (91) The number of national parts (47, 20%) of transmission projects which are not included in the NDPs remarkably decreased compared to the finding of the Agency’s analysis carried out in 2016 (when the number of national parts not included in the NDPs

text: represented 33% of the total), but is still significantly higher than in 2014 (when the share was slightly below 10%) .

text: (92) Most transmission projects which are not included in the NPDs, were not included as they were not advanced enough to enter the NDP or because the commissioning date of the project is beyond the time span of the NDP (i.e. time horizon up to which year a project can be planned). These findings confirm the ones in 2016 (Agency’s Opinion 08/2016 p.5), when the most frequent reason for the absence of a national part in a NDP reported by the NRAs was also related to a commissioning date too far in the future or no sufficient progress.

text: (93) In 8 instances (17%), the national part of a project is not included in the NDP as it is a third-party project and third-party are normally not included in the NDPs.

text: (94) Most of the storage projects were not included in the NDP, due to general non-inclusion of the storage projects in the concerned jurisdictions. Out of the 5 storage projects, which were included, one was only referred to, without any further assessment.

text: (95) 2 investments (corresponding to 3 national parts) have been mentioned by the NRAs as having cross-border relevance, but do not appear in the draft EU TYNDP 2018 . One is an Italian internal investment, another one is an Italian - Austrian interconnection. The Agency notes that, based on the information received by ENTSO-E, these investments were not proposed by the project promoters as candidates for the EU TYNDP 2018.

text: Table 18. Investments which have a cross-border relevance, but do not appear in the draft TYNDP 2018

text: (96) The Agency reiterates its view that, although the NDP is not legally binding in most jurisdictions within the EU, the implementation of the EU TYNDP projects strongly relies on the NDPs. Non-inclusion of a project in the NDP due to other reasons than the 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 on the credibility and feasibility of the implementation of the concerned projects, which feature should be clearly flagged in future EU TYNDPs.

text: (97) The Agency also reaffirms its recommendation that the (approved/scrutinised) NDPs should explicitly flag the cross-border relevant projects and ENTSO-E should include them in the EU TYNDP.

text: 4.3.2. Analysis of project differences in the EU TYNDP 2018 and in the NDPs

text: (98) An assessment of the projects consistency between the NDPs and the EU TYNDP was carried out by the Agency and NRAs, by evaluating differences regarding 7 project features (i.e. technical features, clustering, transfer capacity increase, benefits, status, commissioning date and costs of the projects).

text: (99) As shown in Figure 1, most of the differences emerging from this assessment are related to the commissioning date, followed by the status and transfer capacity increase. These results are similar to previous findings and also appear to be in correlation with the Agency’s finding about the availability of the data in the NDPs and to the NRAs (i.e. that costs and benefits are the most common sources of missing information preventing an assessment of the consistency by the NRAs).

text: Figure 1. Project/investment differences in the NDP and draft EU TYNDP 2018 identified by NRAs

text: (100) The Agency notes that the non-reporting of a difference does not always mean a NRA validation of the data. For 45% of the data assessed in this Opinion (7 characteristics for 259 national parts of projects), the NRAs are not able to assess the consistency (e.g. the project is not mature enough, information is not available to the NRA). In total for 7% of the data the NRAs reported differences and for 45% they confirmed the data in the EU TYNDP 2018. The remaining 3% of the data was not available.

text: (101) Even if difference has been identified in only 7% of data, approximately half of the national parts of the projects listed in the draft EU TYNDP 2018 exhibit at least one substantial differences compared to the NDPs or the NRAs’ most recent information. Although for the vast majority of the (different) national parts one or two differences were identified (67% and 19% respectively), there were national parts (10%) featuring between 4 and 6 differences out of the 7 features.

text: (102) The Agency notes that the draft EU TYNDP 2018 (similar to the EU TYNDP 2016) seems more optimistic in terms of the commissioning date and the advancement status than the relevant NDPs. In this regard, the Agency reiterates it recommendation that in order to avoid excessively optimistic projections on commissioning dates, ENTSO-E should define 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’, the future EU TYNDPs should provide the project promoters’ estimate

text: together with the ‘reference timeline’ estimate. In case of differences, the project promoters should explain them.

text: (103) The Agency notes that misalignments exist between different NDPs regarding some projects, in terms of timing of their implementation, status or cross-border capacities . The Agency is of the view that such misalignments for interconnections could be largely avoided with enhanced consultations and exchange of information between the concerned TSOs on specific projects. Project promoters should inform NRAs of the outcomes of such consultations.

text: (104) The Agency also acknowledges that due to different schedules for the elaboration of plans and other reasons (for example, changes in market fundamentals), the NDPs and the EU TYNDP may temporarily be out of alignment, even if excellent coordination and regular exchanges of information took place.

text: 5. CONCLUSION

text: For the purpose of this Opinion, the Agency has reviewed the NDPs of all EU Member States, with regard to the general regulatory framework and the inputs, outputs and methodologies used of their development.

text: (105) The Agency concludes that these NDPs are broadly consistent with the EU TYNDP 2018 and observes that their consistency with the EU TYNDP improved compared to the previous Agency’s Opinion on the NDPs. This improvement can be explained by:

text: (a) A more widespread practice to move the frequency of the NDP from 1 year to 2 years; (b) The more systematic use of a multi-scenario approach (while previously, about half of the NDPs were developed against a single scenario); (c) A more widespread practice to introduce a CBA for projects and more benefit categories in the NDPs; (d) A more widespread practice to include third-party projects in the NDPs.

text: (106) However, the Agency also notes that different practices are still used for the overall development, review and adoption of the NDPs, and some of them might negatively impact the robustness, credibility and transparency of the NDPs or could result in inconsistencies with the EU TYNDP.

text: (107) Therefore, the Agency identified in this Opinion several areas for improvement.

text: HAS ADOPTED THIS OPINION:

text: 1. The Agency considers that the NDPs reviewed in this Opinion are broadly consistent with the EU TYNDP 2018.

text: 2. The Agency recommends ENTSO-E further to enhance the consistency between the NDPs and the EU TYNDP by implementing the following measures:

text: a. The EU TYNDP should have two separate project Appendices: one listing the mid-term and long term projects (i.e. projects already ‘planned’ and expected to be commissioned within a ten-year period) and the other one listing the ‘future’ projects or studies (i.e. projects ‘under consideration’ or planned to be commissioned beyond 10 years).

text: b. While the ‘best estimate’ approach is appropriate for the short term, the nearterm best-estimate scenario for the EU TYNDP should be completed with appropriate sensitivity analysis. Such sensitivity analysis would be particularly useful in detecting the main factors on which a project outcome (benefits) depends.

text: c. While the multi-scenario approach is appropriate for the long term, so as better to consider the growing uncertainties over time and better to assess the resilience of the investment projects against them, a ‘slow progress’ scenario should be also investigated by the CBA, for all years where multiple scenarios are developed in the EU TYNDPs.

text: d. As regards the scenario-building method, at least one robust scenario with a topdown approach (i.e. consistent and coherent assumptions across Europe) should be developed, which takes into account country specificities. This(ese) scenario(s) should be evaluated in the EU TYNDP and taken into account to construct the NDPs’ scenarios.

text: e. Non-inclusion of a project in the NDP due to reasons other than the time difference in the elaboration of the plans raises doubts on the credibility and feasibility of the implementation of the concerned project and this concern should be clearly flagged in the future EU TYNDPs.

text: f. ENTSO-E should define 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’, the future EU TYNDPs should provide the project promoters’ estimate together with the ‘reference

text: timeline’ estimate. In case of differences, the project promoters should explain them.

text: 3. 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:

text: a. The NDPs should be prepared with a biennial frequency. The NDP should be accompanied by a monitoring update in the years in between.

text: b. The NDPs should include / inform on studies and ‘under consideration’ projects, even if they may go beyond the time horizon of the NDP and clearly flag them as such.

text: c. Ideally, the NDPs should have two separate Appendices: one listing the midterm and long-term projects (i.e. projects already ‘planned’ and expected to be commissioned within a ten-year period) and the other one listing the ‘future’ projects or studies (i.e. projects ‘under consideration’ or planned to be commissioned beyond 10 years).

text: d. NDPs’ scope should be expanded to allow the inclusion of third-party projects, where it is not yet the case.

text: e. A public consultation should be carried out on the draft NDP in each jurisdiction and the results should be published. Information about the treatment of stakeholder comments should also be provided.

text: f. NRAs’ or other public entities’ role regarding the development of the NDPs should be strengthened in those jurisdictions where the TSO adopts the NDP without any regulatory approval or binding scrutiny.

text: g. The NDP and all formal acts on the NDPs, as applicable in each jurisdiction (e.g. decisions, opinion, consistency analysis, monitoring) should be published.

text: h. NDPs should include market studies for projects of cross-border relevance and use the multi-national network models fully to assess the project’s influence on the interconnected network.

text: i. Carrying out a CBA, which allows the comparison of the costs and the benefits of a project, should be considered in each jurisdiction, at least for the larger projects.

text: j. Fundamental project information (i.e. commissioning date, project status, increase of transfer capacity and project cost) should be systematically published. k. NDPs should use a national coding system and cross-referencing with EU TYNDP coding. l. NDPs should explicitly flag the cross-border relevant projects. Done at Ljubljana on 22 May 2019.
