1 EXECUTIVE SUMMARY

1.1 ENTSO-E DELIVERS THE TYNDP 2012 PACKAGE

The European Network of Transmission System Operators for Electricity1 (ENTSO-E) provides herewith the 2012 release of the Community-wide Ten-Year Network Development Plan (TYNDP).

The present report is part of an 8-document suite also comprising the Scenario Outlook and Adequacy Forecast and 6 Regional Investment Plans. Together these form the TYNDP 2012 Package. Complying with present regulations (especially EC 2009/714) and anticipating the implementation of a future Energy Infrastructure package, these 8 reports jointly deliver a structured, both systematic and comprehensive vision for grid development in the coming 10 years in Europe. They describe significant investments in the European power, which are required to achieve European energy policy goals.

1.2 WHAT IS NEW COMPARED TO TYNDP 2010? In a volatile environment, the TYNDP and its methodology are bound to evolve. ENTSO-E targets a delivery every two years of an enhanced product, introducing methodology improvements so as to ensure timely and consistent results, achieving efficiency rather than awaiting perfection.

The first Ten-Year Network Development Plan was published by ENTSO-E on a voluntary basis in Spring 2010, in anticipation of the Directive and the Regulation. The 2012 release builds on this experience and the feedback received from stakeholders. In the last two years, ENTSO-E especially organized two consultations, nine workshops and stakeholders’ meetings in order i/ to discuss scenarios, methodologies, study process, project valuation, and initial results; ii/ to jointly develop more harmonized methodologies; and iii/ to agree on the expected outcomes of a transparent process.

New common top-down-defined and run processes have thus been developed:

• 20-year, Europe-wide scenarios, each displaying a valid generation adequacy assessment, encompassing jointly all foreseeable futures and matching EU 202020 targets (see SOAF 2012);

• Generic planning standards (see “Guidelines for Grid Development”, in Appendix 3); and

1 See www.entsoe.eu.

of 148



• An integrated market and network modeling combining market and network studies in an iterative process.

FIGURE 1: OVERVIEW OF THE GENERAL METHODOLOGY

In order to streamline efforts and ensure consistency, regional and pan-European perspectives are built together in an integrated process.

Projects of pan-European significance – i.e. candidate Projects of Common interest – have been defined (see Appendix 2) and 3rd parties, i.e. non-ENTSO-E members, had the possibility to submit candidate projects by complying with a public procedure advertised at the beginning of the process.

Finally, the presentation of projects in the TYNDP 2012 has been reshuffled to display both a synthetic technical description of every investment item; and the cost benefit analysis of every project, through a multi-criteria assessment scale (see Appendix 3).

1.3 WHAT ARE THE SCENARIOS FOR THE COMING DECADE? Grid development requires the anticipation and consideration of the long term. Notwithstanding the Electricity Highways 2050 works ongoing, ENTSO-E developed 4 visions up to 2030 to examine the challenges and opportunities for TSOs development of longer-term scenarios. Within these visions, 2 scenarios2 have been used as a basis for the TYNDP 2012:

• The scenario EU2020 has been built top-down, based on the European 20-20-20 objectives and the NREAPs3 (it is the reference scenario);

• The scenario SAF-B extrapolates information from market players’ present investments perspectives in a bottom-up approach.

2 Visions and scenarios for this TYNDP 2012 are depicted in SOAF 2012.

3 National Renewable Energy Action Plans: each EU Member State published their roadmap towards the EU202020 targets.

of 148



Both scenarios however match the EU and Members States 202020 goals:

• Power demand evolution results from contradicting effects of, downward, the present economic crisis, strong energy efficiency measures, and, upwards, the switch by end-uses from fossil fuel to electricity (heat pumps, electric vehicles...) and development of electronic devices. At the perimeter of the ENTSO-E system, the peak load in January continues growing by 8% in scenario EU2020 over the coming decade.

• Renewable energies boom, mostly wind and photovoltaic, providing by 2020 as much as 38% of the electricity demand in scenario EU2020.

• Depending on the share of gas and coal-fired units in the mix in the coming ten years, CO2 emissions of the power sector also sink from 26% to 57% in scenario EU2020.

Scenarios have been validated in a public consultation early 2011. The re-stated decisions of German government regarding nuclear phase-out plans led ENTSO-E to test a sensitivity with respect to the presence/absence of nuclear units in this country in order to ensure robustness of the results.

1.4 WHERE ARE THE MAJOR INVESTMENT NEEDS? In the coming decade, the net generating capacity will increase by about 250 GW, i.e. 25% of the present total. Almost all the increase can be explained by RES development (about 220 GW). The figure however hides the important decommissioning by 2016 of obsolete fossil-fuel-fired units not compliant with the emissions thresholds set by the Large Combustion Plant Directive, partly substituted by the commissioning of new conventional power plants (mostly gas, but also coal and nuclear).

All in all, about a third of the present net generating capacity will be built in the coming decade. New generating capacity is almost fully located farther from load centers, RES including: wind generation develops mostly as large wind farms, also offshore. The major shift in the generation mix will therefore induce a massive relocation of generation means and, with large wind and solar capacities, more volatile flows, requiring the grid to adapt.

Market studies can appraise the resulting gross commercial exchange patterns by 2020. As shown in Figure 2 below, Italy, the UK, Poland and Baltic states remain major importing countries; France and Scandinavia are the larger exporters, as is the case today, however, exchanged volumes are higher. Germany, Spain and Portugal experience high exchange volumes but for both imports and exports, which results in an overall balance. Rather logically, the highest volumes are exchanged in the heart of Europe.

FIGURE 2: POWER EXCHANGES PATTERNS4 IN 2020 BETWEEN ENTSO-E COUNTRIES

Market studies basically show larger, more volatile power flows, over larger distance across Europe, mostly North South from Scandinavia to Italy, between mainland Europe and the Iberian Peninsula, Ireland and UK; or East to South and West in the Balkan Peninsula. Investment on grid is needed to avoid present congestion worsening and new congestion appearing.

About 100 bottlenecks can be identified on the European network by the end of the decade, as displayed in Figure 3 below. About 60% of the concerns are primarily related to market integration (either between price zones, or intra-price zones), about 30% primarily related to generation connection and 10% primarily related to security of supply. However 80% of the bottlenecks are related to RES integration, either because direct connection of RES is at stake, or because the network section or corridor is a keyhole between RES and load centers. The north-south internal corridors in Germany are typical examples of the latter.

4 The annual power flows shown on the map do not reflect actual physical power flow on the grid but simplified expected commercial exchanges.

1.5 WHAT ARE THE GRID INVESTMENTS FOR THE COMING DECADE? Over 100 transmission projects of pan-European significance have been identified to address and solve the abovementioned concerns in the coming decade (among them, 40% are interconnectors).

About 79% of the investment items in the TYNDP 2012 package were previously included in the TYNDP 20105 and are hence confirmed. 21% are new ones, which is a bit more than what the regular turnover of the TYNDP process could be expected to be. These figures show both the robustness of the TYNDP 2010, and that the TYNDP is a living process. Overall, there has been material delay to the delivery of one third of the investments, mostly because of social resistance and longer than initially anticipated permitting procedures, possibly leading to project reengineering.

As displayed in the figure below, projects of pan-European significance total about 51500 km of new or refurbished Extra High Voltage routes, split rather equally between the two 5-year sub-periods. It represents a 23% increase compared to TYNDP 2010, especially with individually long-stretching new investments: +3000 km of subsea routes are envisaged, developing in total 10000 km of offshore grid key-assets; +7000 km of routes are considered inland, mostly to bring to load centers the power generated on the outskirts of the European territory.

FIGURE 4: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE - VOLUMES

5 52 of the 495 investments items contained in the TYNDP 2010 have been commissioned, to date. (12 have been partly commissioned, 26 are expected to be commissioned in 2012.)

Projects of pan-European significance are very diverse, adapting to the very specific geography they are inserted in. They develop grid transfer capability (GTC) ranging from a few hundreds of MW to more than 4 GW. Globally, increases to GTC are basically developed where higher power exchanges are expected, as displayed in the figure below:

FIGURE 6: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE – CONTRIBUTION TO EU ENERGY POLICIES

80% of the projects contribute to RES integration (either for direct connection or serving RES energy movements across Europe): transmission grid development at the European level is required for about 125 GW of new RES, i.e. half of the expected RES development

in Europe.

47%6 contribute significantly to market integration, enabling each generation costs savings of at least 30 M€/yr, which equates to greater than 100 M€/yr including the benefit of the integration of the four regions currently with the weakest integration to the European system namely: Italy, the Iberian Peninsula, Ireland and the UK and Baltic states.

Globally, comparing the situation before and after grid reinforcement, the analyses show that transmission projects of pan-European significance will help alleviate total generation

operational costs by about 5%. Most savings are expected in the abovementioned countries.

33%7 of the projects are required to integrate isolated systems such as the Baltic States, secure large load centers (in particular capital cities), or even countries with negative generation adequacy forecast in the coming years.

All projects contribute to significantly mitigating CO2 emissions in Europe (with the exception of the few direct connections of fossil-fuel-fired power plants).

All the projects also display high technical performances (see Figure 7). A project’s technical resilience and flexibility can be substantially influenced by TSOs and consequently projects of pan-European significance typically show robust design. On the other hand, other characteristics such as losses are influenced greatly by other exogenous factors, and there the project’s benefit in such areas are diverse: positive effect on losses for those merely improving grid meshing/interconnection; negative when connection of new remote generation is at stake; and undetermined when the appraisal is more complex.

FIGURE 7: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE – TECHNICAL ASSESSMENT

Total investments costs for projects of pan-European significance amount to € 104 billion, of which € 23 billion is for subsea cables. The figures are is in line with the previous analysis of the TYNDP 2010 and the overall € 100 billion envisaged by the European Commission in their communication on the Energy Infrastructure Package on 17th Nov 2011.

This effort is significant for TSOs financial means. It equates however to about 1.5-2 €/MWh of power consumption in Europe over the 10-year period, i.e. only around 2% of the bulk power prices or less than 1% of the total end-users’ electricity bill.

1.6 WHAT IS THE RESILIENCE OF THE PROPOSED INVESTMENTS? Thousands of market situations, which consider all hazards that may affect the power system have been simulated and processed for this TYNDP 2012. Frequent situations, or rare ones but resulting in particularly extreme flow patterns, have then been identified for further

analysis, in order to test the grid’s ability to withstand them; and to define if necessary the required measures. Such typical situations are at peak load in winter or summer, with extreme but probable low or high wind/solar generation. Thus, TSOs can ensure the proposed investments are adaptable, valuable and robust.

Are all investment needs identified in the coming decade appropriately solved by the proposed transmission projects? It is highly likely that the proposed investments solve the transmission issues for all of the generation connection or security of supply projects: these are rather well limited and easier to address. Projects also fully meet requirements of market integration in the foreseen scenarios, except for rare situations that are still feasible for certain rather open and interacting concerns. Sizing investments to match these rare situations would however not prove profitable for European countries. .

Resilience is also ensured by the fact that TYNDP 2012 project designs use cutting edge technologies. Some of them are new technology demonstrators and world premieres: largest DC VSC equipment, longest AC cable route, DC and AC parallel operation... Aside from the proposed extra high voltage investments, TSOs also contribute to the development of smartgrids8: latest electronic tools and IT systems help optimizing the operation of existing assets, and especially monitor, forecast and control distributed RES and load management.

Visions for 2030 are a step toward 2050, where the EU advocates 100% RES power generation. 2050 scenarios and analyses are still ongoing, in the framework of the Electricity Highways 2050 consortium led by ENTSO-E. Even before this work is complete, it emphasizes that the trends depicted in the present TYNDP report will continue developing in the coming decades: generation moving to the periphery of the European area, mostly with offshore RES and coastal large conventional units; hence, larger, more volatile power flows over larger distances in Europe; as a result, grid development is primarily triggered by generation development.

ENTSO-E thus believes that the pan-European TYNDP constitutes a solid and robust synthesis of the required development of the European grid.

A major challenge is that the grid development may not be in time if the RES targets are met as planned by 2020. Permit-granting procedures are lengthy, and often cause commissioning delays. If energy and climate objectives have to be achieved, it is of upmost importance to smooth the authorization processes. In this respect, ENTSO-E welcomes the proposals made by the European Commission with the draft Energy Infrastructure Package, as there are many positive elements in the permitting section that will facilitate the fast tracking of transmission infrastructure projects including the proposal of a one-stop shop and defined time lines. More thorough analyses are, however, required so as to ensure the measure can be successfully implemented, particularly in relation to whether the timelines proposed are achievable, and particularly in the context of the public participation process and the potential for legal delays. One must also notice that the supporting schemes are limited to the so-called Project of Common Interest (PCIs) whereas there are many significant national

8 See the ENTSO-E R&D Plan (in https://www.entsoe.eu/resources/key-documents/).

of 148



transmission projects that are crucial to the achievement of Europe’s targets for climate change, renewable and market integration.

1.7 WHAT ARE THE NEXT STEPS? The quality of the integrated market and network modeling relies on the knowledge of all specific parameters of each local power system in Europe; as well as the resulting ability to master and cut aptly through numerous uncertain parameters. The aim is to properly model every grid concern in a limited timeframe, and therefore correctly valuate just over 100 projects from right across Europe.

ENTSO-E hence devised a specific top-down coordination, both relying on common standards and subsidiarity to take advantage of TSOs’ local expertise and workforce. This organization will be improved to address new challenges but must continue to rely on this combination of top-down lead and decentralized expertise.

The TYNDP 2012 enabled ENTSO-E to implement for the first time a cost benefit analysis, articulating market and network studies. ENTSO-E believes that the developed methodology is a good basis in the perspective of the future Energy Infrastructure Package. The valuation of projects and the integrated realization of both the pan-European and regional reports are intended to efficiently support the selection of Projects of Common Interest in the Regional Groups. Scenarios in the SOAF are released every year to accommodate every required update. ENTSO-E now expects stakeholders’ feedback to further develop the methodologies to deliver the TYNDP. The preparation of the TYNDP 2014 has already started!

Beyond the coming decade, ENTSO-E also anticipates longer-run needs: ENTSO-E Regional Group North Sea directly contributes to the North Seas offshore grid concept for 2020/2030 following the Memorandum of Understanding for the North Seas Countries’ Offshore Grid Initiative (NSCOGI). Also, ENTSO-E leads a consortium in charge of the “e-Highway2050” study, which seeks to develop a strategic plan that will provide a vision for a pan-European power system, built around the Electricity Highways concept developed in sequence over the time horizon to 2050.

2 INTRODUCTION

2.1 ENTSO-E SUPPLIES A VISION FOR GRID DEVELOPMENT IN THE

COMING 10 YEARS IN EUROPE: THE TYNDP PACKAGE 2012 The European Network of Transmission System Operators for Electricity9 (ENTSO-E) provides herewith the 2012 release of the Community-wide Ten-Year Network Development Plan (TYNDP).

The objectives of the TYNDP are to ensure transparency regarding the electricity transmission network and to support decision-making processes at regional and European level. This pan-European report and the appended Regional Investment Plans are the most comprehensive and up-to-date European-wide reference for the transmission network. They point to significant investments in the European power grid in order to help achieve European energy policy goals.

2.1.1 COMPLYING WITH EUROPEAN REGULATIONS The present publication complies with the requirements of Regulation EC 714/2009, in force since March 2011 whereby (According to Art. 8.3-b) “ENTSO-E shall adopt a non-binding Community-wide 10 year network development plan, including a European generation adequacy outlook, every two years”10.

The Regulation set forth that the TYNDP must “build upon national investment plans” (the consistency to which is monitored by the Agency for the Cooperation of Energy Regulators, ACER), “and if appropriate the guidelines for trans-European energy networks”. Also, it must “build on the reasonable needs of different system users”. Finally, the TYNDP must “identify investment gaps, notably with respect to cross-border capacities”.

2.1.2 A STRUCTURED, BOTH SYNTHETIC AND COMPREHENSIVE, MATERIAL Stakeholders require for grid development synthetic and detailed perspectives at the same time. ENTSO-E faces the challenge by supplying the “TYNDP package 2012”, a suite of documents consisting of 9 See in Appendix § A2.1 and for more information www.entsoe.eu.

10 Legal requirements set for the TYNDP by Regulation 714/2009 are summed up in Appendix § A2.1.

of 148



• the present Community-wide TYNDP report 2012;

• the 6 Regional Investment Plans 2012; and

• the Scenario Outlook and Adequacy Forecast 2012.

All these documents present information of European importance. They complete each other, with limited repetition of information from one document to another only when necessary to make everyone of them sufficiently self-supported:

• Scenarios are comprehensively depicted in the SOAF;

• Investments needs and projects of European importance are comprehensively depicted in the Regional Investment Plans;

• The present Community-wide TYNDP report hence only sums up synthetic information for concerns and projects of pan-European significance.

Every document is designed to be between 50 and 100 pages long, not accounting for appendices. Generic information presented in the TYNDP 2010, especially section 2 and 3 regarding the organization of the European power system and the challenges for grid development is not recalled in the present edition.

The TYNDP 2012 package is consulted in Spring 2012 in order to be finalized in June 2012.

2.2 A TOP-DOWN, OPEN AND CONSTANTLY IMPROVING PROCESS The first Ten-Year Network Development Plan was published by ENTSO-E on a voluntary basis in Spring 2010, in anticipation of the Directive and the Regulation. The 2012 release builds on this experience and the feedback received from stakeholders.

In the last two years, ENTSO-E organized in this respect two consultations, regarding the TYNDP 2010 in Spring 2010, and the scenarios for the TYNDP 2012 in Winter 2011; as well as nine workshops, in Brussels or regionally, about scenarios, methodologies, study process, projects valuation, and first results11. The Florence forums, conferences, dedicated meetings with DG Energy, ACER and market players also contributed to sharing concerns, jointly developing more and more harmonized methodologies and agreeing on the expected outcomes of the process.

FIGURE 8: TYNDP 2012 ELABORATION SCHEDULE

WHAT’S NEW WITH THE TYNDP 2012 PACKAGE? ENTSO-E have proposed, submitted to stakeholders and implemented the following improvements since 2010:

• A new organization framework:

o ENTSO-E designed and ran top-down for the present TYNDP submission new common study procedures: common top-down-defined and consulted scenarios (see SOAF 2012), generic planning standards (see Appendix 3) and specific study protocols for joint studies bases of TYNDP 2012.

o In order to streamline efforts and ensure consistency, regional and pan-European perspectives are built together in an integrated process, considering six regions relevant to addressing grid development issues in Europe. (Regions are overlapping to ensure overall consistency of the Regional Investment Plans.)

FIGURE 9: ENTSO-E SYSTEM DEVELOPMENT REGIONS

o The possibility for 3rd parties (non-ENTSO-E members) to submit candidate projects by complying with a public procedure12.

• Improved outcomes, directly answering stakeholders request when consulted about TYNDP 2010:

o Identification of main future congestions issues on the grid and assessment of bulk power flows across these;

o Explicit definition of projects of pan-European significance (see §A2.5 in appendix);

o Higher-level presentation of projects, showing connections between investments to develop additional grid transfer capability;

o Valuation of every project benefits assessment to enable cost benefit analysis;

o Synthetic assessment of the transmission adequacy expected with the planned investments.

In a volatile environment, the TYNDP and its methodology are bound to evolve. ENTSO-E targets a regular delivery every two years of an enhanced product, introducing methodology improvements so as to ensure timely and consistent results, thus achieving efficiency rather than aiming at perfection.

The following chart sums up the overall process: basically open to stakeholders; constantly improving; integrating efficiently both pan-European and regional exercises (see Chapter 4 for more details).

3 ASSESSMENT OF TYNDP 2010 This chapter deals with the evolution of projects planned in TYNDP 2010. It compares the evolution of the table of project in Appendix 1 of the TYNDP 2010 and TYNDP 2012 reports.

3.1 ROBUSTNESS OF THE TYNDP 2010 INVESTMENT PORTFOLIO

The structure of the table of projects has evolved compared to the TYNDP 2010, especially based on stakeholders’ feedback:

o The investments items are now clustered into larger projects to display both a synthetic technical description of every investment item and the cost benefit analysis of every project;

o The labeling build on the investment items’ references supplied in the TYNDP 2010 report. Additional investment items are labeled “Axxx”;

o A specific column monitors the evolution of every investment item from TYNDP 2010 to 2012.

The diagram below illustrates the evolution of the TYNDP Project table between the 2010 and 2012 publications:

FIGURE 11: EVOLUTION OF PROJECTS FROM TYNDP 2010 TO TYNDP 2012

Out of 495 investments items presented in the TYNDP 2010,

of 148



• About 75% are present in the pan-European TYNDP 2012 report;

• 52 have been commissioned, to date (12 have been partly commissioned, 26 are expected to be commissioned in 2012);

• 106, expected to be commissioned after 2012 are now presented in the Regional Investment Plans 201214;

• 12 have evolved in their design or have been entirely substituted (the correspondence can be monitored in the table of project “status evolution from 2010 to 2012”)

24% of the investments in the pan-European TYNDP report 2012 have been newly introduced. This figure compares to the 17% of the investment planned in the TYNDP 2010 that are now completed or about to be completed. This is a relatively normal turn-over although a bit high, but matching the evolutions of investment needs in Chapter 6. These figures show both the robustness of the TYNDP 2010 which is here confirmed; and that the TYNDP is a living process.

In total, 486 investment items are now clustered into a few more than 100 projects of pan-European significance (see Chapter 7 and Appendix 1 for more details)

3.2 MONITORING OF PROJECTS OF TYNDP 52 investment items have been completed. The following chart shows the progression of all the projects detailed in the TYNDP2010 that are still to be commissioned, in order to illustrate whether the stated delivery timescales for the investments have been met. The projects have been classified as either “delayed”, “on track” or “ahead of schedule” depending on whether the expected commissioning date for each has changed.

5% of the investments are ahead of schedule. This is mostly the case of investments where consensus among stakeholders has been reached earlier than expected: the business plan has hence been validated earlier enabling to entering the permitting phase.

More than 55% remain on track. It can be generally concluded that good progress has been made as the delivery timescales for the projects move from the long-term to the mid-term.

That withstanding, there has been material delay to the delivery of one third of the investments, mostly because of social resistance and longer than initially expected permitting procedures, possibly leading to project reengineering. For example, some sections of new proposed overhead power line routes have had to be substituted with the use of underground cables. The phenomenon is not specific to certain countries or regions. On average, delayed investments are delayed a bit longer than 2 years.

4 METHODOLOGY FOR TYNDP 2012

4.1 MARKET AND NETWORK INTEGRATED MODELING ENTSO-E developed for the present TYNDP 2012 the target-methodology introduced in Chapter 8 of the TYNDP 2010.

As summed up in the figure below, the top-down target methodology breaks down into 4 steps, detailed hereafter:

FIGURE 13: OVERVIEW OF THE GENERAL METHODOLOGY

The present chapter deals with the specific methodological features developed for the TYNDP 2012. Generic planning standards are presented in Appendix 3.

4.1.1 SCENARIOS TO ENCOMPASS POSSIBLE FUTURES The first step is the construction of scenarios (see definition in Appendix, § A2.3). Each scenario must show intrinsic logic and consistency, especially a valid generation adequacy15 and all scenarios must encompass all foreseeable futures. Scenarios are built for the entire Europe to ensure global consistency. They comply with visions until 2030 in order to provide longer-run perspective. They have been publicly consulted.

The reference scenario for the TYNDP 2012 is the ‘EU2020’ scenario, and all results are presented by default for this scenario. It is a top-down scenario, deriving from the policy goals the EC and Member States16 set themselves for 2020. The other basic scenario “B” derive from a bottom-up approach, based especially from presently known intentions of

16 ��7�� 6�.��

of 148



market players. The scenarios eventually rather converge, showing shared consensus regarding the achievement of the EU 202020 targets.

Variants of these scenarios may have been analyzed additionally, to accommodate specific local options whenever needed. Especially, sensitivity to the shut-down nuclear power plants have been considered.

Scenarios are synthetically presented in Chapter 5 and detailed in the SOAF 2012.

4.1.2 MARKET STUDIES TO DERIVE ECONOMIC BALANCES For every scenario, a market study answers the question “which generation (location/type) is going to serve which demand (location) in any future instant?”. Their outcome is market balances in every country/price zone and especially generation, and exchange patterns (“bulk power flows”).

To perform a market study, the demand must be modeled, and usually as dependent on weather conditions. Additionally, generation connected to the distribution level, and thus seen as negative demand from TSOs, or smart grids may lead to the need to enrich this model. At the same time, the generation features (especially a cost function) must be modeled, and these depend on several parameters such as raw material prices, financial situation, geopolitical evolutions, meteorological conditions, etc. Systems experiencing energy constraints, as for example those with significant part of hydro storage capacities, need to adopt annual or pluri-annual scopes in order to take into account time of production optimization.

The modeling of all market components’ behavior is thus huge. Most market study tools rely on probabilistic modeling. Conversely, the modeling of the transmission grid itself must rely in most cases on a 1-node-per-country (or price zone) principle with simplified transmission capacity limitation modeling between the nodes. Because of computation limitations, available tools show different trade-off with more or less detailed modeling of every market item versus network feature. They have been developed to match specific characteristics of hydro-systems here or delicate thermal unit commitment there.

ENTSO-E thus organized for the elaboration of the TYNDP 2012 the possibility to run in parallel several market study tools at regional levels, in order to better adapt to specifics of every region on the one hand, and mutually challenge the models to derive more robust results. The variety of outcomes of market studies are presented in Regional Investment Plans. All the simulations however are derived from a single database depicting the scenarios to ensure consistency between all six European regions.

of 148



4.1.3 NETWORK STUDIES TO ASSESS GRID TRANSFER CAPABILITY Network studies answer the question “will the dispatch of generation and load given in every case generated by the market study result in power flows that endanger the safe operation of the system (accounting especially for the well-known N-1 rule)?” If yes, then transmission projects are designed, tested and evaluated for all relevant cases. Studied cases explore a variety of dispatch situations: frequent ones, or rare ones but resulting in particularly extreme flow patterns. A limited set is chosen to map the whole range of situations identified in the market studies.

Inputs to common network studies are default pan-European Power Systems Models (PSMs), where the specific generation and load dispatch stemming from the market studies is blended. PSMs are datasets, depicting transmission assets, with default topology and an “example case”. ENTSO-E regularly organizes data collection to update and make available to all TSOs these basic datasets.

The methodology for network studies is depicted in Appendix 3, Guidelines for Grid Development. Basically, network studies help assessing the grid transfer capability, and its increase enabled by transmission projects. This output of the network studies can be retro-fitted in market studies to assess improvement brought by the enhanced grid to the market.

Market studies (assessment of all cases with simplified grid description) and network studies (extensive grid description for one particular case) are thus duals. They are wisely articulated in a two-step, iterative process in order to ensure consistency and efficiency (every concern being properly addressed with the appropriate modeling) and to avoid too complex all-in-one black-box models either too complex to run or lacking detailed enough modeling of some aspects.

4.1.4 AN EXPLICIT AND PRACTICAL VALUATION OF PROJECTS The network value develops from the combined action of all grid assets interacting with each other. Stakeholders wished to get a better idea of how the proposed investments interact. Isolating objectively the specific impact of every investment is, however, very complex because of the network effect17.

The presentation of projects in the TYNDP 2012 has hence been reshuffled to display both a synthetic technical description of every project item and the cost benefit analysis of every project.

Transmission projects are valuated against the following multi-criteria scale developed by ENTSO-E (see Appendix 3 for the definitions):

17 Schematically, the added value of all assets is greater than the sum of their individual values,ceteris paribus.

FIGURE 14: PRINCIPLES OF MULTI-CRITERIA ASSESSMENT OF PROJECTS OF PAN-EUROPEAN SIGNIFICANCE

Projects basically improve the grid transfer capability and an assessment of the grid transfer capability increase is provided for every project. All other dimensions are assessed via 3-level indicators:

• The social and economic welfare indicator, the RES integration indicator and improved security of supply values the benefits of the projects in the 3 dimensions of the EU Energy policy: market integration, RES development and security of supply;

• The RES integration, losses variations and CO2 emissions variation indicators value the benefits with respect to the three pillars of the 202020 policy;

• The technical resilience and flexibility indicators refer to the technical performance of the assets in the grid;

• The social & environmental impact completes the costs, date of commissioning and the status of the project as well as show risks attached to the project completion.

The assessment of the benefits compares the situation with and without the projects, ceteris paribus.

4.2 A SPECIFIC, TOP-DOWN, EUROPE-WIDE COORDINATION This new top-down methodology represents a great improvement compared to the previous release of the TYNDP. The whole process has been implemented for the first time, by ENTSO-E and all 41 TSOs members to deliver the TYNDP 2012 package, involving huge amounts of data and new models.

ENTSO-E is already building on the gathered feedback to strengthen all the involved procedures and further improve the methodology implementation. The goal is threefold: to

of 148



accelerate and strengthen data collection, consistency checks and processing; to facilitate common model calibration; to coordinate regional groups, articulate pan-European and regional assessment and merge all results consistently.

The quality of the integrated market and network modeling described supra relies on the knowledge of all specific features of every local power system in Europe as well as the resulting ability to master and cut aptly through numerous uncertain parameters. The aim is to model properly every grid concern in a limited timeframe of 2 years, and hence valuate correctly more than 100 projects all over Europe.

ENTSO-E hence devised specific top-down coordination, both relying on common standards and subsidiarity to take advantage of TSOs’ local expertise and workforce:

• 1 working group coordinating the TYNDP 2012 delivery and 3 working groups of key-experts to set up methodologies and organize data framework, for planning standards; scenarios and market studies; power system models.

• 6 regional groups, gathering TSOs experts, jointly performing regional analyses, sharing views, mutually challenging and jointly building solutions, each group able to focus on the specific concerns of their area.

As a result, about 200 people in Europe contributed to the TYNDP 2012 package. Be they all thanked for their commitment.

5 SCENARIOS This chapter deals with the assumptions used to develop the results presented in the TYNDP 2012 package. The presented material gives the main conclusions of the SOAF 2012 report and the market studies that have been carried out in the Regional Investment Plans.

5.1 LONG-TERM VISIONS AND SCENARIOS The development of the transmission grid requires a long-term vision that is robust for relevant developments that determine the future use of the grid. In the SOAF 2012 report the pan-European ENTSO-E energy visions for 2030 are presented. In these four visions, four credible, coherent and consistent energy projections until the year 2030 are described. Although 2030 is beyond the scope of this TYNDP, these visions are the background against which the ENTSO-E scenarios will look at in the future.

The SOAF 2012 report presents an update of the scenarios that were developed in SOAF 2011, have been publicly consulted and commented on in the first semester of 2011, and used as bases of the analyses. The re-stated decision of German government regarding nuclear phase-out plans led ENTSO-E to test a sensitivity to the presence/absence of nuclear units in this country in order to ensure robustness of the results.

Two pan-European scenarios were established to assess the system adequacy in this TYNDP. The two scenarios, being EU2020 and SAF-B, describe different paths of relevant parameters until the year 2020.

• In the scenario EU2020, the European 20-20-20 objectives and the NREAPs18 were the starting point and the necessary evolution towards this target has been filled in (top-down). The EU2020 scenario is used as the reference scenario and reported by default.

• For scenario B the present situation is taken as a starting point and the future developments are extrapolated until 2020 based on the best estimate (bottom-up).

The evolution of new generation in the top-down scenario is interpolated between the current situation and the end vision: therefore information about the location of new generation must be also assumed top-down, whereas in the bottom-up scenario the evolution of the system derives from market players’ known intentions, and the location of new generation match them.

18 National Renewable Energy Action Plans, each EU member state published the roadmap towards the EU202020 targets.

of 148



Toward a sustainable future As the European Commission is preparing a directive to make a further step in improving energy efficiency in a context where energy represents around 80% of the greenhouse gas emissions, TSOs are enlarging their approach to better contribute to energy efficiency. TSOs cannot directly control the use of energy by end-users: however, they can contribute by enabling the use of new technologies or concepts such as efficient generation, demand side management, smart grids and energy storage.

TSOs support energy efficiency, considering the following criteria to qualify the efficiency of energy: • Environmental footprint (CO2, renewability) • Affordability • Reliability and availability • Losses Thus, with their efforts to develop their transmission network in order to enable renewable energy sources to evacuate their power, TSOs play an active and positive role in realizing environmental neutral generation. The market-focused tools developed by TSOs make it possible to lower the use of expensive electricity generation when the consumption decreases, which participates in the economic aspect of energy efficiency. By developing their network, TSOs enable the use of new power plants, which in major cases generate electricity with a better efficiency than older ones. By this, more efficient and affordable generation becomes available to a larger market.

Of course, TSOs have been fighting to control their energy losses for long, for these weigh directly on TSOs’ energy efficiency as well. It seems useful to remember at this stage, that with constant levels of transit (generation and consumption remaining equal), network development (new lines) implies less losses (though a low effect), thus a higher energy efficiency� However, the current main driver for new corridors is usually the need for more transit, with connected losses. The transmission of electrical energy introduces losses that increase with the magnitude of the flow and the distance of the transport. TSOs have been spending much effort to reduce the losses as much as possible by using extra high voltage.

As the TYNDP includes numerous projects either dedicated to connecting new renewable energy sources, or more energy-efficient power plants, or bound to transporting this efficient energy towards consumption areas, grid development projects play a major role on the way to the 20% energy-saving target.

5.2 RENEWABLE ENERGY BOOM BY 2020 In the SOAF 2012 report, a projection of the evolution of load and generation are presented. In Figure 15 the generation mix for 2012 and 2020 is displayed.

FIGURE 15: EVOLUTION OF THE GENERATION MIX (EU 2020 SCENARIO, IN GW)

The total of installed capacity will increase by 250 GW, i.e. by 26%, to reach 1214 GW. This increase is mainly due to wind and solar generation which will be developped by 220 GW by 2020. These generation technologies are by nature not controlled and the power system will have to adapt to greater RES outputs. Scenario B also shows a significant RES development, but about 22 GW lower than scenario EU 2020. The installed capacity of fossil fuel units increases by 14 GW in scenario B, while in scenario EU 2020, it slightly decreases (2 GW).

In parallel, the total system peak load will continue to increase, between 2012 and 2020, by about 30 GW and will reach 567 GW in the reference scenario. New conventional generation develops in pace with the load growth. The overall generation adequacy is threfore assumed to be ensured by the end of the coming decade. (More details are available in the SOAF 2012 report.)

5.3 EUROPEAN POWER EXCHANGES BY 2020 Market studies have been conducted to simulate the behavior of the power system by 2020 (see Chapter 4). All situations likely to occur during the 8760h of the year have been analyzed. The following map synthesizes the results, displaying for every border the magnitude of the energy exchanged in every direction; and for every country the magnitude of the net yearly energy balance.

France and Scandinavia are the biggest exporters and the United Kingdom, Italy, Poland, Belgium and the Baltic States have a clear import position. Other countries such as Spain or Germany show a rather balanced position on average, but can experience significant bidirectional flows to neighboring countries due to the intermittency of RES.

6 INVESTMENT NEEDS Once scenarios have been defined, the next phase in network planning consists of characterizing the Investment needs, i.e. every concern ahead on the regional grid and of European significance, and which are likely to trigger extra-high voltage grid investment in order to restore the grid ability to fulfill the duties and services expected from this infrastructure.

Investment needs are described in the present Chapter 6, before solutions to accommodate them are summed up in the next Chapter 7.

6.1 PRESENT SITUATION The map Figure 17 depicts cross-border transfer capacities nowadays20:

The map shows diverse level of Net Transfer Capacities (NTC) in Europe. These discrepancies basically match the geography and demography of Europe: highest NTC levels (and highest grid density generally) are met in the central part of the continent where there is also the highest population density (and hence higher consumption, and installed generation), from London to Milan. South East Europe also shows a consistent pattern with similar interconnection capabilities all across the area, but at a globally lower level than in more densely populated areas.

6.2 DRIVERS OF POWER SYSTEM EVOLUTION Drivers for grid development directly derives from the three pillars of EU energy policy goals: Security of Supply; Renewable energy integration; Internal Market integration.

The map Figure 18 (next page) shows the main primary drivers21 for grid development in Europe in the coming decade (see definition in Appendix 2, §A2.4):

• Large amount of RES spread all over Europe, with concentration in Iberian Peninsula, in the South of Italy, and North Seas neighboring countries. About 220 GW of new RES generation are foreseen (see SOAF 2012 report).

• Power plant decommissioning22: about 25 GW of nuclear capacity is scheduled to be shut down from 2010 to 2020, especially in Germany (16 GW) and the UK (7 GW). Obsolete coal-fired power plants are also scheduled to be shut down in order to meet environmental standards, especially in the UK (9 GW). The decommissioned power plants were mostly located relatively close to the most populated areas in Europe, possibly resulting in security of supply issues.

• In total, about twenty large areas (shown by amber dots) with specific supply are at risk unless transmission capabilities are improved or local generation develops.

• The relatively low interconnection of Baltic States regarding neighboring EU states.

• Cyprus and Iceland are island systems. No interconnectors with other ENTSO-E countries have been considered in the TYNDP package 2012.

21 As the case may be, any other investment needs (ageing of equipment, reliable grid operation, decommissioning of smaller units, etc.) are shown in Regional Investment Plans.

22 To clarify the picture, only decommissioning of power plants larger than1 GW that are not replaced on site by new generation – and changing hence the power flow patterns – are described.

6.3 MAIN BOTTLENECKS POSSIBLY DEVELOPING IN THE COMING DECADE As a result of the market and network study process, almost 100 possible bottlenecks have been identified in Europe in the coming decade (unless new transmission assets are developed).

The map Figure 19 (next page) shows their location, i.e. the grid sections (the “boundaries”), the transfer capability of which may not be large enough to accommodate the likely power flows that will need to cross them unless new transmission assets are developed.

In order to ease the understanding, the likely bottlenecks have been sorted according to three types of concerns:

• Security of supply when some specific area may not be supplied according to expected quality standards and no other issue is at stake;

• Generation direct connection;

• Market integration, if inter-area balancing is at stake, distinguishing what is internal to a price zone and what is between price zones (cross-border).

NB: when a boundary can be flagged with more than one concern, then, somewhat arbitrarily, Market integration prevails over Generation connection and Security of Supply.

• About 60 % the boundaries are primarily related to market integration issues, 40% cross-border and 20% internal. Most present cross-border congestions can be recognized on the map, as they would just develop unless new grid assets are implemented.

• About 30% are primarily related to generation direct connection;

• About 10% are primarily related to security of supply issues.

As shown infra, the above sorting hides that boundaries flagged “market integration” are almost all contributing to RES integration (see § 6.4.1). Some of them are also related to security of supply issues (see § 6.4.3).

6.4 EXPECTED BULK POWER FLOWS BY 2020 A Bulk power flow is the typical power flow triggering grid development across a boundary. They are quantified in the following sections for every concern. Bulk power flows range from about 500 MW to more than 10000 MW.

6.4.1 GENERATION CONNECTION The map of generation integration (Figure 20 next page) shows the boundaries that are related to direct connection of renewable or conventional facilities to the grid. It highlights:

• Higher bulk power flows (amber and red) where there are big concentration of new generation

o developing in a limited area, especially offshore wind in the North Sea;

o adding up to already large concentration of generation (Scotland, Wales, Alps, Rhone Valley)

• Lower bulk power flows (blue and green) where large amounts of RES develop where relatively little generation was installed: in Ireland, Portugal, Spain, Southern Italy, Greece, Bulgaria and Romania, Poland, and Nordic countries.

• Lower bulk power flows (blue) where large power plants are planned in Germany, Poland, Lithuania, and Finland.

6.4.2 MARKET INTEGRATION The map Figure 21 (next page) displays market integration concerns:

FIGURE 21: BULK POWER FLOWS RELATED TO MARKET INTEGRATION

The map shows:

of 148



• Relatively larger bulk power flows in the heart of Europe than on the periphery of the continent. This is a rather mechanical result: the area spreading from Benelux to the Alp region is denser, and geographically located at the crossroad of the European power system compared to other countries.

• Compared to other peripheral areas, Ireland and the UK show remarkably higher bulk power flows (amber rather than green or blue). The generating fleet will experience a deep renewal, and obsolete nuclear and coal-fired power plants will be substituted especially by wind generation. As all wind turbines in the area show very correlated output profiles, large surpluses or deficits are likely and hence more variable exchange patterns with mainland Europe.

• The largest bulk power flows related to market integration are located in the central part of Europe, and are oriented North South between:

o generation concentration along and off the North Seas shores and high RES development in Southern Italy; and

o large consumption areas (Benelux, Paris area, South of Germany, North and Central Italy, Mediterranean Sea shores from Spain to Italy) with relatively low installed generation (and even lower with unit decommissioning);

o hydro storage in Scandinavia and the Alps, with pumping capacity.

From North to South, the power system alternatively shows generation and consumptions areas. As a result, the power flows are large, but also more volatile than today: for instance, in summer the Southern part of Germany will show surpluses every day and deficits every night.

• On a parallel corridor, there are much larger North-South flows in Baltic States, Poland and Central-East Europe than the present transfer capability of the grid allows for.

• There are much larger East to West and South flows in South-Eastern Europe than the present transfer capability of the grid allows for.

6.4.3 SECURITY OF SUPPLY OF LARGE AREAS The map Figure 22 (next page) locates and quantifies all security of supply concerns:

• Supply of large cities or urbanized areas (Lisbon, Catalonia, French Riviera...);

• Countries with a negative generation adequacy forecast (Belgium, Luxembourg) requiring additional cross-border transmission capacity23;

• Regions within countries with a negative generation adequacy forecast (South of Germany, Brittany, North West Hungary, Northern Norway) requiring additional transmission capacity;

• Baltic States requiring a higher interconnection with EU countries to ensure their supplies.

6.5 RES INTEGRATION AS THE MAJOR CONCERN The breakdown into security of supply, generation connection and market integration in § 6.4 is useful for better understanding and comparisons of every single concern.

However 80% of the bottlenecks are directly related to RES integration (see Figure 23), either because direct connection of RES is at stake; or because the network section or corridor is a key-hole between RES and load centers. The north-south internal corridors in Germany are typical example of the latter. The following map displays the overall picture, with, in lighter green the boundaries related to the accommodation of inter-area transits triggered by RES; and in darker green the boundaries related to direct connection of RES generation (or to both concerns as the case may be).

The massive development of RES is the main driver for larger, more volatile power flows, over larger distance across Europe, mostly North-South from Scandinavia to Italy, between mainland Europe and the Iberian Peninsula, Ireland and the UK; or East to South and West in the Balkan Peninsula.

The next Chapter 7 deals with grid investments that are hence needed to avoid present congestion to worsen and new congestion to appear.

23 See SOAF 2012. Conversely, when the generation adequacy forecast of a country is acceptable without accounting for import capacity, no security of supply issue is marked on the map. The countrymay however require imports to mitigate electricity prices. Italy is an example of such situation.

7 PROJECTS OF PAN-EUROPEAN SIGNIFICANCE To solve all investment needs identified for the coming decade in Europe, the European TSOs evaluated in collaboration numerous grid reinforcements.

The pan-European TYNDP report focuses on projects of pan-European significance (see definition in Appendix 2, § A2.5). Projects with more regional (resp. national) focus are presented in the ENTSO-E Regional Investment Plans (resp. National Development Plans).

Every project of pan-European significance is listed, described and valuated in Appendix 1. The present Chapter provides an overall view about the projects, their costs and benefits.

Projects promoted by 3rd parties

In order to deliver the most comprehensive and up-to-date outlook of the electricity grid by 2020 and beyond, ENTSO-E, based on the stakeholders’ feedback to the TYDNP 2010, elaborated and made publicly available in February 2011 as part of the TYNDP development process, a procedure for the inclusion of the third party projects in the 2012 release of the TYNDP: https://www.entsoe.eu/system-development/tyndp/tyndp-2012/.

ENTSO-E- received five submissions, analyzed in every relevant Regional Group. The candidate projects however did not demonstrate evidence of a transmission license or an exemption for such license granted by the relevant national regulatory authorities and the EC, in accordance with the TYNDP procedure. The non-discrimination principle (especially with regard to similar projects that may not have applied for inclusion for this reason), makes it inappropriate for these five projects to be incorporated in the table of projects of the TYNDP 2012 package.

7.1 GRID DEVELOPMENT PROJECTS OF PAN-EUROPEAN SIGNIFICANCE

ARE NEEDED ALL OVER EUROPE The following two maps geographically display all investments item composing the projects of Pan-European Significance. The first map (Figure 24) shows all projects commissioned mid-term, i.e. in the first five-year period of the TYNDP, from 2012 to 2016; the second map (Figure 25) shows all projects commissioned in the longer run, i.e. from 2017. The maps show basic information regarding location, routes and technology (AC or DC, voltage level). When the precise location of an investment is not yet known, the area where the investment

of 148



is likely to occur is colored. The investment labels ease the correspondence with the table of projects in Appendix 1.

The maps show projects of pan-European significance basically planned all over Europe, with a relative balance between long-term or mid-term. Projects are rather well defined for the coming five years. Longer-run projects may still be in planning or design & permitting phases: they may not be precisely designed and located yet, and several options might still be envisaged for some of them.

7.2 OVER 50000 KM FOR GRID TO BUILD OR REFURBISH IN THE COMING

10 YEARS Over 100 transmission projects of pan-European significance have been identified to address and solve the abovementioned concerns in the coming decade. (Among them, 40% interconnectors).

As displayed on Figure 26 below, projects of pan-European significance total about 51500 km of new or refurbished Extra High Voltage routes24. The expected commissioning dates are split rather equally between the two 5-year sub-periods.

FIGURE 26: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE - VOLUMES

The TYNDP 2012 figures represent a 21% increase compared to TYNDP 2010, with especially individually long-stretching new investments. +3000 km of subsea routes are envisaged, developing in total 10000 km of offshore grid key-assets; +7000 km of routes are considered inland, mostly to bring to load centers the power generated on the outskirts of the European territory.

The vast majority of project (around 39000 km) use the common HVAC technique. This is the common technical standard in Europe for electricity transmission and is a well-established

technology. In addition, about 12600 km of HVDC links are planned. Most relate to subsea investments where AC technology is no option. Several HVDC interconnection projects are however considered inland with parallel operation with HVAC lines. 1080 km of HVAC subsea cables, at 150 kV or 220 kV are also planned, mostly for offshore wind connection.

Over 80% of the investments correspond to new equipment/routes and 20% to refurbishment or upgrade of existing assets.

7.3 GRID TRANSFER CAPABILITY INCREASE BY 2020 As developed in Chapter 6, the challenge of the coming decade is to face larger and more volatile power flows across larger distance in Europe. The proposed grid reinforcements hence focus on Grid Transfer Capability (GTC) increase.

The GTC increase enabled by every project is presented in Appendix 1. The following map (Figure 28, next page) synthesizes the outcome across all boundaries in Europe. The values of gained GTC are oriented by needs and cover a huge range of transmission capacity increase efforts: projects of pan-European significance are very diverse, adapting to the very specific geography they are inserted in. They develop GTC ranging from a few hundreds of MW to more than 4 GW. Globally, greater GTC increases are developed basically where higher power exchanges are expected.

Larger GTC increases correspond to situations where parallel investments combine their effort across a large boundary where large bulk power flows are expected (for instance, between Ireland and the UK and mainland Europe). Lower amounts correspond to more specific situations (new power plant connection for instance).

7.4 PROJECTS BENEFITS The projects’ impacts were assessed by the multi-criteria assessment developed by ENTSO-E (see Appendix 3) to show the benefits of each project.

7.4.1 A DIRECT SUPPORT TO THE EU ENERGY POLICY The charts shown below (see Figure 29) illustrate the magnitude of support given by the projects to the EU energy policy. The corresponding benefit is considered in terms of four criteria: Social and Economic Welfare, RES Integration, Security of Supply and CO2 Emissions Mitigation.

FIGURE 29: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE – CONTRIBUTION TO EU ENERGY POLICIES

As a result of the strict criteria applied25, the Socio-Economic Welfare (SEW) indicator has a very strong correlation with market integration. High-marked projects correspond mostly to

of 148



additional interconnectors with four network peninsulas: Ireland and Great Britain, Spain and Portugal, the Baltic States, and Italy.

80% of the projects show high benefits for RES integration, half by directly connecting RES, and half by accommodating inter-area unbalances triggered by RES. Projects still marked low with respect to RES integration either contribute specifically to connecting nuclear or conventional generation or for securing the supply of load areas at risk.

With respect to the Security of Supply, 13% of projects are classified as High, meaning the project will secure an area for at least ten years after commissioning. 24% are classified as Medium, meaning the project will contribute to securing a specific area but for less than ten years after commissioning. (If more than one project is required to secure an area for more than ten years, then none can be individually classified as High. This is the case for projects securing Belgium and the Baltic States.)

All projects reduce the CO2 emissions with the exception of a small number of projects that are solely for the integration of new fossil-fuel-fired power plants.

7.4.2 HIGH TECHNICAL PERFORMANCE STANDARDS All the projects also display high technical performances (see Figure 30):

FIGURE 30: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE – TECHNICAL ASSESSMENT

The charts for Flexibility and Technical Resilience illustrate that for such technical factors, for which a TSO has a wide degree of freedom to influence, very high performance can be achieved. This is in contrast to other objectives which are strongly affected by factors which cannot be significantly controlled by a TSO such as the location of generation.

In this latter respect, losses for instance depend on exogenous factors, and projects benefits in this respect are diverse (as explained in the insert below): positive for those merely improving the grid meshing; negative when connection of new remote generation is at stake; and undetermined when the appraisal is more complex.

of 148



Grid losses variation

Transmitting electrical energy causes electrical losses, the more distance and the higher the energy, the higher the losses.

An efficient way to reduce losses is to operate the grid at higher voltage and thus reducing the electrical current. However, equipment for higher voltage is more costly and therefore an economic equilibrium between (investment) costs and benefit (reduction of losses) is chosen at the design of the extra-high voltage grid. Typically in Europe voltages of 400 kV and 220 kV are used to transport electrical energy over large distances. In itself the extra-high voltage grid is already designed to be as efficient as possible to minimize the overall costs.

The effect on overall losses of a single transmission line is fairly small; it should not be expected that the losses indicator in the TYNDP will reveal a major step in efficiency of the grid, the big step has already been made with the introduction of the extra high voltages. Some projects however can have a substantial positive effect on electrical losses.

The Assessment Alternatives

The assessment of the losses of a single project is not straightforward. There are various perspectives and ways to assess the losses in the grid, all with other outcomes.

1. The project can be assessed by itself. This means that the amount of loss on the lines in the project can be evaluated. The effect on the other parts of the interconnected grid is neglected which would give a very narrow view on the effect of losses. The outcome of this indicator using this method for assessing would be that new projects will have losses, more or less depending on the project design; voltage upgrades of existing lines could reduce the losses.

2. The project can be assessed as a part of the European Transmission Grid. A comparison between the European grid with and without the project can be made without modifying the load and generation profile. In general this would mean that for a grid extension project the overall impedance would decrease and the losses would reduce; in case of decommissioning the losses would also generally increase.

3. The project can be assessed, taking into account its effect on GTC. In case a project increases the GTC on a specific corridor, more energy can potentially be transmitted along that corridor. This would potentially mean a different running arrangement for generators; an increase of generation in the congested area, and a decrease of generation in the non-congested area. A different GTC results in a different running arrangement of generators over the hours in the whole year. The two configurations are not easily comparable anymore. Therefore a planning case by planning case assessment of efficiency is not meaningful and year-round comparisons should be made. For instance, connecting offshore wind farms that would substitute fossil-fuel-fired units closer to load centers would result in higher losses on the total grid – in general only a marginal drawback compared to the total increase of social and economic welfare.

of 148



The assessment of the grid losses variation derives for every project from the most suitable approach considering its specific features.

7.4.3 A DIFFICULT SOCIAL ACCEPTANCE OF PROJECTS The social & environmental index measures the risk that a project might not be completed at the expected commissioning date. Results are displayed in Figure 31:

� ��

��

��

��

FIGURE 31: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE – SOCIAL AND ENVIRONMENTAL IMPACT

This indicator reflects the perception of risk, which may vary depending on every national context. Project promoters of course indicate low risk when the target date is still to be more accurately defined, in the long run; or when projects are under construction, and close to being completed. Conversely, projects in the permitting phase are almost all classified as Medium or High-risk.

(See Appendix 4 for more details about social acceptance issues)

7.4.4 5% OF SAVINGS IN GENERATION OPERATING COSTS Comparing the power system costs to, on the one hand, present, limited, NTCs26, and on the other hand future NTCs once projects of pan-European significance are implemented, shows that long-term cross-border transmission projects of pan-European significance will help alleviate total annual generation operational costs by about 5%. For higher generation costs that can be expected by 2020, this represents about €5 billion.

Most of the savings are expected from the integration of the four regions showing presently the weakest integration to the European system: Italy, the Iberian Peninsula, Ireland and the UK, and the Baltic states.

26 Only benefits of increased NTCs are measured here. Investment costs for the corresponding long-term cross-border projects amount to about €20 billion.

FIGURE 32: “ELECTRIC PENINSULAS” IN EUROPE BY 2020

7.5 ABOUT €100 BILLION INVESTMENTS IN THE COMING 10 YEARS Project costs show a very wide range, corresponding to the diversity of the projects’ designs (see Appendix 1), from less than €50 million to more than €1 billion: 40% of the projects display costs lower than €300 million and 23% greater than €1 billion.

The following table (Figure 33) figures out the total expected investments cost per country27 for all projects of pan-European significance28,29:

27 This is the best available information to date. Figures however keep adjusting for every project and the information is subject to changes for every country.

FIGURE 33: INVESTMENT COSTS BREAKDOWN

Total investments costs amount to € 104 billion, of which € 23 billion is for subsea cables. The figures are is in line with the previous analysis of the TYNDP 2010 and of the overall € 100 billion envisaged by the European Commission in their communication on Energy Infrastructure Package on 17th Nov 2011.

Total investment costs per country correlate relatively with land size and population. Still there are noticeable deviations. Ireland thus foresees as much as €4 billion (due mostly to HVDC long-distance cables), an important effort compared to the population size. With big evolutions with respect to generation location on the German ground, Germany considers by far the highest investments, with €30.1 billion.

The investment efforts are significant for TSOs financial means. It represents however about 1.5-2 €/MWh of power consumption in Europe over the 10-year period, i.e. about 2% of the bulk power prices or less than 1% of the total electricity bill.

8 TRANSMISSION ADEQUACY Are all investment needs identified in the coming decade appropriately solved by the proposed transmission projects?

It is most likely for every generation connection or security of supply issue: these are rather well limited and easier to address.

Projects also match requirements of market integration in the foreseen scenarios, except for rare situations that are still possible for these rather open and interacting concerns. Sizing investments to match these rare situations would not prove profitable for European countries.

The TYNDP 2010 recognized some seven main clusters of investment needs related to renewable integration, East-West and North-South flows in the South-East and Central South regions, Baltic States integration, connection of new conventional power plants and supply of some European cities and regions, and market integration.

Checking against those needs one can state that the direct renewable connection needs are solved almost in all the cases except in the parts of Northern Spain. However, a lot of transmission needs stem from the fact that the RES are located away from the consumption centers, which shows on the North-South transmission needs.

There are more uncertainties linked in the transmission adequacy for North-South flows in Northern, Central and Southern Europe. German nuclear phase-out has created some uncertainty for the transmission adequacy of the proposed projects inside Germany. The TYNDP package reflects results as far as available in January 2012.

France-Spain interconnection stands out. With all projects included in this TYNDP 2012, it is still expected that the interconnection will have congestions more than 50% of the time. However, from the TSO’s point of view, the projects have to be implemented step by step, and they are complex enough so that it is not possible to commission more than one project in a timeframe of 6 years.

In South-East Europe there are uncertainties for the East-West transmission adequacy linked with the possible new undersea DC tie lines between Balkan and Italy, the connection of Ukraine and Turkey to the rest of the Europe and a huge potential of RES in the overall region that could, with new transits from Ukraine, Turkey, Romania and Bulgaria, make congestions on the above mentioned directions.

Baltic States will surely be integrated more tightly to the rest of the European electricity system but according to the studies there will be some situations where the transmission capacity might not be enough for the market needs.

of 148



To summarise, there are only a few cases where additional measures are certain to be needed on top of the proposed projects in the plan. However, there is a level of uncertainty for residual congestion in some rare conditions or a need for further investigations in some areas. This can of course change if the assumptions behind the analysis change, for example, with more ambitious renewable targets or other sudden large changes in the system, like the decision on nuclear phase-out in Germany has shown.

9 HIGH ENVIRONMENTAL STANDARDS Presently, the European transmission network consists of ca. 305000 km of routes. Completing the projects of pan-European significance will lead to refurbishing about 10000 km of existing assets and building 42000 km of new assets, increasing the total length of the network by 14% over the coming ten years (of which 70% are overhead, and 30% underground or subsea).

9.1 A RELATIVELY LIMITED NETWORK GROWTH DESPITE A MAJOR SHIFT

IN GENERATION MIX

An equivalent of about one third of the present net generating capacity will be built in the coming decade. New generating capacities are almost all located farther to load centers, RES especially (wind generation develops mostly as large wind farms, also offshore). The major shift in the generation mix will hence induce a massive relocation of generation means and, with large wind and solar capacities, more volatile flows, requiring the grid to adapt. This represents for the adaptation of the generation fleet a rate of 3%/yr.

On the other hand climate change mitigation will require energy-efficiency measures (including in the power sector) but also transfer from fossil-fuel based end-uses to CO2-free energy sources. European power peak load is thus expected to grow slightly in all scenarios by 7 to 8% over the next ten years (see SOAF 2012). This represents 0.7%/yr for the load growth.

The major driver for grid development is therefore generation. In comparison to the 3%/yr for the generation adaptation rate, the grid’s growth rate looks relatively modest, with 1.3%/yr. This illustrates once more the “network effect”, where the output developed by all elements together is greater than the summated output of every individual element.

9.2 A STRONG SUPPORT TO EU ENERGY POLICIES, WITH EFFICIENT

RESOURCES COMMITMENT By nature, projects of pan-European significance aim at supporting EU energy policies. The diagram below shows how many out of the 51500 km of either upgraded or new assets contribute to all of the three pillars of the EU Energy policy:

��

��!!�"��

FIGURE 34: PROJECTS OF PAN-EUROPEAN SIGNIFICANCE – VOLUME BREAKDOWN PER EU ENERGY POLICY PILLAR

It should be noted that, if summated, the total volumes of circuit kilometers for each pillar (84800 km) would be greater than the total physically constructed (51500 km) as it is possible for a single project to fulfill several requirements at the same time. This again illustrates that network development proves to be a productive and efficient way to invest and reach several high-level goals at once, while reducing environmental impacts greatly by sparing resources.

The commissioning of projects of pan-European significance will result in CO2 savings of 170 MtCO2, of which 150 MtCO2 results from the connection of renewable generation technology and 20 MtCO2 which stem from saving following further market integration (mostly “electric peninsulas”).

The projects of pan-European significance allow around 125 GW of renewable generation to be integrated in the power system and are thus required for about half of the expected RES development in Europe (about 220 GW).

10 RESILIENCE ASSESSMENTThe main objective of transmission system planning is to ensure, with respect to the mid- and long-term horizon, the development of an adequate transmission system which contributes to

• Security of Supply, Transmission grid ensures safe system operation and provides a high level of security of supply.

• Sustainability, Transmission grid allows for the integration of renewable energy sources.

• Competitiveness, Transmission grid facilitates grid access to all market participants and contributes to social welfare through internal market integration and harmonization.

This chapter will firstly describe how the plan answers to the technical and economical assessment and then describes the technological development and long-run issues.

The more detailed description of the Planning standards can be found in Appendix 3.

10.1 A PLAN ROBUST TO ALL REASONABLY LIKELY SITUATIONS The transmission grid is designed for future needs. It needs to cope with the situation that will be there, not just fix problems encountered today. For this aim several future scenarios or sensitivity cases are needed for the basis of the plan. The new infrastructure should fit in with the existing infrastructure, and also should not hinder any long-term future development.

TSOs perform complex system and grid studies to check the system behavior under extreme conditions.

There are two commonly agreed main background scenarios: EU2020, B-scenario. Sensitivity to the shut-down nuclear power plants has been considered. Regional analyses have been done for these in an all-year-round analysis. Thousands of market situations, considering all hazards that may affect the power system have been simulated and processed for this TYNDP 2012.

Regionally most restrictive cases based on the possible future situations have been studied in grid studies in order to check the secure functioning of the grid after the projects are commissioned. High-load cases, low-load cases, high/low renewable production cases, different hydro years in the Nordic system and other regionally constrained cases have been studied.

The detailed results of the studies can be found in the Regional Investment Plans .

of 148



The system has been verified both for the capacity that the proposed projects will give and for the technical functioning against the common ENTSO-E planning standards, see Appendix 3.

10.2 A PROFITABLE INVESTMENT PLAN FOR EUROPE Investments should positively address social welfare.

Socio-economic assessment of a project is carried out in order to evaluate its economic viability and overall impact. TSOs systematically undertake such studies. In general, the assessment takes into account the foreseen investment costs and benefits of the new projects. The investment costs are subject to uncertainties concerning the permitting processes or other supply chain considerations, and include capital/operational cost, etc. On the other hand, benefit evaluation is a more demanding exercise since for example some technical improvements (for Security of Supply) or pursuing policy objectives (integration of renewable sources) are difficult to quantify.

Grid investments help so that bottlenecks are removed and so renewable generation is not bottled somewhere in the grid. This also includes how the benefits should be looked at on a wider pan-European level.

The total benefit in generation savings for the long-term projects regarding the market integration in this Plan (in total about €20 billion investment) has been analyzed to be €5 billion/year; therefore, there is definitely a positive economical value of the projects notwithstanding the other benefits that have not been changed into monetary value.

10.3 IMPLEMENTATION OF EDGE TECHNOLOGIES The challenge of grid development must be met by use of cost effective solutions and without any disturbance for the whole reliability of the European transmission. The technologies employed to date in the transmission grids are efficient, reliable, well engineered and are widely available techniques for transferring energy in high-voltage grids. The ongoing technology progression, predominantly driven by special applications, has led to new techniques that may have the potential to be employed in the future transmission grid. Of course, it is not possible to give a comprehensive description of all the research done about grid operation and development in the present report. Appendix 5 supplies a more detailed perspective. For further information, the reader is invited to refer to the ENTSO-E R&D Plan30.

New 400 kV AC OHL projects are in technical, economic, and ecological terms the most efficient solution for long-distance electricity transmission. Indeed, such reinforcements 30 See the ENTSO-E R&D Plan (in https://www.entsoe.eu/resources/key-documents/).

integrate straightforwardly into the existing grid since this technology has been the standard for a long time. In addition, other solutions are implemented to accommodate specific situations when necessary.

This chapter deals with novel techniques as well as unconventional techniques, i.e. known technologies that have not been widely used for various reasons. Basically technologies can be sorted into four categories depending on their maturity: mature (PST), in large-scale testing phase (real-time thermal rating, low sag conductors), in the development phase (FACTS) and in the research phase (superconductors, nanotechnology).

Some illustrations on the more novel and unconventional technologies that have been selected for the projects in this plan:

Underground Cables. There are examples in the plan where an AC cable has been deemed as an appropriate technology selection. These are mostly short connections in the order of some tens of kilometers.

High Temperature Conductors (HTCs). This technical choice has been made for several projects of the TYNDP: the 260 km long 400 kV overhead line between France and Italy, 275 km in the French Rhône Valley, an ongoing upgrade of a 220 kV line in Poland...

The High Voltage Direct Current (HVDC). More than 40 HVDC links representing some 13000 km of routes, mostly undersea and located in north, west, central and south Europe, are described in the TYNDP 2012. Nevertheless, some cables are to be installed onshore, e.g. between France and Spain or Belgium and Germany.

Underground and submarine XLPE (Cross-Linked Poly-Ethylene) cables, some above mentioned HVDC projects consider the use or will use XLPE cables.

HVDC combined with AC. Some projects combine HVDC and HVAC solutions, like the South-West link in Sweden and Norway.

Combined Grid Solution. Krieger’s’ Flak could be mentioned as a project combining offshore Wind integration with interconnectors between Denmark and Germany.

Gas Insulated Line (GIL) pilot project in the Brenner Tunnel being currently under consideration between Italy and Austria, constituted of a 65 km long double circuit 400 kV Gas Insulated Line.

Phase Shifting Transformers (PSTs), which help better controlled active power through preventive or curative strategies. There are several projects including PST devices, for example a dozen of Phase Shifting Transformers are to be installed in Europe in the coming ten years, like in Zandvliet (4th PST on the Belgian north border).

Flexible Alternating Current Transmission System (FACTS). Several projects in the Plan includes FACTs devices, such as SVC's.

Several novel technologies can be mentioned that can be considered as a possible help in operations, but do not appear as a full part of the TYNDP list of investments.

of 148



Real-Time Thermal Rating (RTTR)-monitored cables/lines, or Dynamic Line Rating, are on their way to becomine a mature technology based on the real-time control of the thermal rating of a line or a cable.

Fault Current Limiters (FCLs) comprise technologies with different degrees of maturity.

Wide Area Monitoring System (WAMS) is an information platform with monitoring purposes. Based on Phasor Measurement Units (PMUs), WAMS allow monitoring transmission system conditions over large areas in view of detecting and further counteracting grid instabilities. This early warning system contributes to increasing system reliability by avoiding the spreading of large area disturbances, and optimizing the use of assets.

Electric Storage: as for now, there are around 15 projects in Europe, which are limited to the connection of hydro pump power plants, mainly in Switzerland, Austria, Romania, Spain and Portugal. As for storage demonstration projects, the TWENTIES project involving several ENTSO-E members, responding to the ENERGY 2009.7.1.1 call (optimization of the electricity grid with large-scale RES and storage) can be quoted, as well as the Almacena project in Spain.

Storage capacity development in Europe

Recent evolution of the renewable energy source in most of the European countries, supported by favorable incentive schemes, by quick permitting procedures and by network reinforcement, suggests the TSOs to bring up a few additional issues for the forthcoming years. In order to comply with the third energy package the further development of the electricity systems should be carried out in the most efficient way, reducing the bottlenecks on the transmission grid and developing new technologies for the management of the intermittent production. Beyond grid reinforcements, which aim to increase the transmission capacity by avoiding the wind curtailment, storage systems might prove efficient and profitable facilities to cope with the future increase of the wind and photovoltaic sources, see Figure 35 below:

FIGURE 35: REDUCTION OF ENERGY CURTAILMENT WITHOUT/WITH STORAGE

The boom of RES installations has been sustained thanks to the TSO effort to follow the investment needs; therefore most of the new capacity has been connected either to the new transmission grid or to an upgraded portion. Moreover, the intermittent generation, having a priority access to the network, put out of the market the thermal generation decreasing the availability of reserve. Therefore, electricity systems with high penetration of RES are exposed to the risk of a difficult management of the margin reserve, in particular during the off-peak load period.

In order to reduce constraints to full access of RES generation, new power capacity is first required. Meanwhile, a more flexible management of the energy produced by RES is strongly required taking into account the capacity to be installed within 2020 in compliance with the national action plans. Such a process needs the involvement of all the users to develop the electricity system, starting with the TSOs to develop the grid; quick permitting procedures of new lines/substations/transformation, are therefore very important to speed up the authorization process. System needs are in the meanwhile development of other facilities, characterized by an easy construction.

As a conclusion, storage facilities might be a complement, and not an alternative way, to the grid development in order to allow:

• resolution of grid congestions,

• peak shaving ,

• reserve for the electricity system,

• primary frequency regulation.

Depending on their location, storage systems might need coordination of TSOs and DSOs to supply connection to the grid and take full advantage of the solution.

Smartgrids The term „Smart Grids“ usually refers to distribution rather than transmission systems. From the technical point of view, many “smart” features which the Distribution System Operator (DSO) of the future will be able to employ are already available to and implemented by the Transmission System Operators (TSOs) nowadays. Among these features are

• massive communication in real time between virtually all nodes in the system

• active and reactive power flow control based on real-time measurements

• loss optimization via optimal power flow algorithms

of 148



• legal provisions for redispatch, countertrading, market interruptions, cross-border remedial actions, etc.

Network development as tackled in the TYNDP is indirectly concerned with the ongoing development of the distribution systems. The more active role of the networks themselves as well as the expected more active participation of loads and generation embedded in the distribution systems will impact on the forecast of the load as well as, in the long run, the design of the market models used to simulate the behavior of the system participants. ENTSO-E is actively involved in the design of the network codes necessary to accommodate smart distribution grids and will continue to tune the tools used in the elaboration of the TYNDP accordingly.

TSOs strive to make the best use of existing assets implementing technologies such as PST, HTLS, and FACTS, in order to achieve an efficient grid development or as an interim measure where grid extension cannot be realized in a timely manner. When grid extension is needed, proven new technologies are widely resorted to fulfilling transmission tasks. TSOs also anticipate future challenges with live-texting of promising new technologies through pilot projects.

Some of the technologies are still in a premature state and a large-scale integration of these technologies in the transmission grid is not possible due to reliability constraints. As the TSO’s have the responsibility for the whole electrical system in their control zone, precaution is needed with respect to the introduction of new technologies.

As a matter of fact, none of the examined technology is a universal solution. Each project has to be considered in a dedicated study assessing the best fitting technologies.

For that reason, some technologies will play a real role in the European TSOs’ transmission projects in the next ten years, and some other technologies do not appear yet, for their level of maturity and reliability are not satisfying yet within this timeframe.

10.4 A MILESTONE TOWARD ELECTRICITY HIGHWAYS 2050 First step toward Electricity Highways 2050

Most of the grid we have today, will still be there for a long time. In addition the grid that we build today will be there for at least the next 40-60 years. The existing grid and the future grid should be compatible with each other.

TYNDP and the projects in the plan are the first step toward the Electricity Highways 2050.

FIGURE 36: TOWARDS 2050

In the 2050-perspective the EU energy system is expected to undergo a fundamental transformation. This is brought about by the production of large and intermittent wind volumes predominantly in the Northern Seas and large-scale solar in Southern Europe and possibly in Northern Africa and the Middle East along with the developments in storing and consuming electricity and in decentralized models of electricity generation (see Figure 37 below).

The consistency of the EU’s and ENTSO-E’s strategic visions and needs is extremely important in order to address the necessities arising according to all projections for the penetration of carbon-neutral technologies in the future energy mix, with production often located in very distant areas from consumption and storage areas.

In a context of a full decarbonized energy future, the question will be raised on how to solve the RES generation fluctuation (see Figure 38 below), and how to transform yesterday’s “generation follows load” into a tomorrow’s “load follows generation” principle.

FIGURE 38: CHALLENGES OF A FULLY RENEWABLE ENERGY SOURCES BASED ELECTRICITY SYSTEM IN 2050

Acknowledging this, ENTSO-E has stressed the importance of consistent long-term transmission planning, supported by novel planning approaches based on dedicated R&D efforts. In line with the proposal for an Energy Infrastructure Package (comprising of two Regulations, namely the “Guidelines for the Implementation of European Energy Infrastructure Priorities” and the “Connecting Europe Facilities”), as published in October 2011, ENTSO-E tries to assess how a pan-European Electricity Highways System should be built over a time horizon to 2050. A study roadmap was provided in 2011, in order to frame a Modular Development Plan on a pan-European Electricity Highways System (MoDPEHS) for 2050.

Based on this study, the modular development plan shall now be developed by a study consortium consisting of ENTSO-E and its members, relevant professional associations, Research Institutes, Universities, etc. within the “e-Highway2050” study project, which should start in the course of 2012.

The “e-Highway2050” study seeks to develop a strategic plan that will provide a vision for a pan-European power system, built around the Electricity Highways concept developed sequentially over a time horizon to 2050.

of 148



The approach will start from the pan-European transmission network by 2020, which is assumed to be known and in line with the 2020 EU energy targets. Thus, the project aims at covering the time period beyond ENTSO-E’s Ten-Year Network Development Plan. It will consider two important first steps: The TYNDP as a basis, and also the North Seas offshore grid concept for 2020/30, following the Memorandum of Understanding for North Seas Countries’ Offshore Grid Initiative (NSCOGI). The “e-Highway2050” study project aims at:

• developing future-oriented novel planning approaches, allowing a comprehensive but efficient Electricity Highways discussion,

• analyzing and justifying bulk power transmission needs, taking into account future generation and its spread throughout the whole transcontinental region,

• proposing concrete implementation, operation and governance principles for needed grid investments throughout Europe and to neighboring areas,

• in the interest of security, efficiency, feasibility and sustainability, considering the whole energy supply chain including relevant technical/technological, economical/financial, ecological political/sociopolitical and geopolitical/security issues,

• following a modular approach: 2030, 2035, 2040, 2045 and 2050, • and finally, proposing general strategic Electricity Highways architectures including

technology options. The modular long-term planning roadmap will be provided by using two parallel approaches, based on the same macro-scale scenarios:

• a scenario approach using linear power flow approximations for the network modeling and semi-quantitative cost benefit analysis techniques to propose an expansion plan for 2020-2050,

• improvements for the above expansion plan, taking into account critical issues using novel planning techniques (correlated uncertainties in energy and power scenarios, voltage problems and stability considerations, black-out risks) in order to make the above expansion plan more robust.

Both planning approaches will consider the whole energy supply chain, including all the relevant technical/technological, economical/financial and regulatory/socio-political dimensions needed to develop efficient, yet sustainable, grid architecture options meeting future energy supply requirements. Scenarios on generation, storage capacities and consumption patterns will be detailed based on stakeholder consultations and in-depth work with professional associations. As part of the “e-Highway2050” dissemination process, respective progress reports along the three-year study project will support the TYNDP 2014 process, as the starting point for sketching intermediary steps reflecting the increase of decarbonization of the electricity systems.

11 CONCLUSION

11.1 RES INTEGRATION IS THE MAJOR CHALLENGE FOR GRID

DEVELOPMENT IN THE COMING DECADE The TYNDP 2012 studies show basically larger, more volatile power flows, over greater distances across Europe. About 100 bottlenecks can be identified on the European network by the end of the decade. About half of the concerns are primarily related to market integration (either between price zones, or intra-price zones), one third primarily to generation connection and 20% primarily to security of supply. However 80% of the bottlenecks are related to RES integration, either because the direct connection of RES is at stake, or because the network section or corridor is a keyhole between RES and load centers. The north-south internal corridors in Germany are typical example of the latter.

11.2 REQUIREMENT TO BUILD OR REFURBISH OVER 50000 KM OF

NETWORK, FOR AROUND €100 BILLION A bit more than 100 transmission projects of pan-European significance have been identified to address the abovementioned concerns in the coming decade. About 79% of the investment items of the TYNDP 2012 package were already present in the TYNDP 201031 and are hence confirmed. 21% are new ones, which is a little greater than what could be anticipated from the inherent, regular turnover of the TYNDP process. These figures show both the robustness of the TYNDP 2010; and that the TYNDP is a living process.

Projects of pan-European significance total about 51500 km of new or refurbished Extra High Voltage routes, split rather equally between the two 5-year sub-periods. This figure represents a 23% increase compared to TYNDP 2010, which in the main stems from new investments of very long circuits: +3000 km of subsea routes are envisaged, developing in total 10000 km of offshore grid key-assets; +7000 km of onshore routes are being considered, mostly to bring to load centers the power generated on the outskirts of the European territory.

It should be noted that the planned projects are in direct support of the EU energy policy:

31 52 investments items have been commissioned, to date. (12 have been partly commissioned, 26are expected to be commissioned in 2012.)

of 148



• 80% of the projects contribute to RES integration (either for direct connection or serving RES energy movements across Europe): transmission grid development at European level is required for about 125 GW of new RES, i.e. half of the expected RES development in Europe.

• 47%32 contribute significantly to market integration, enabling each generation costs savings of at least 30 M€/yr, which increases to more than 100 M€/yr when the integration of the 4 regions with the weakest current integration with the European system are considered: Italy, Iberian Peninsula, Ireland, the UK and Baltic states. Globally comparing the situation before and after grid reinforcement, the analyses show that long-term cross-border transmission projects of pan-European significance will help alleviate total generation operational costs by about 5%. Most savings are expected from the abovementioned countries.

• 33%33 of the projects are required to integrate isolated systems such as the Baltic States, secure large load centers (in particular capital cities), or even countries with negative generation adequacy forecast in the coming years (ex: Belgium).

• All projects contribute to significantly mitigating CO2 emissions in Europe (but the few directly connecting fossil-fuel-fired power plants).

Total investment costs sum up to € 104 billion, of which € 23 billion is for subsea cables. The figures are in line with the previous analysis of the TYNDP 2010 and the overall € 100 billion envisaged by the European Commission in their communication on the Energy Infrastructure Package on 17th Nov 2011. This effort is significant for TSOs financial means. It represents however about 1.5-2 €/MWh of power consumption in Europe over the 10-year period, i.e. only around 2% of the bulk power prices or less than 1% of the total electricity bill.

11.3 ENTSO-E PROVIDES STRONG SUPPORT FOR EU ENERGY POLICIES The quality of the integrated market and network modeling relies on the knowledge of all specific features of every local power system in Europe; as well as the resulting ability to master and cut aptly through numerous uncertain parameters. The aim is to model properly every grid concern in a limited timeframe, and hence valuate correctly slightly more than 100 projects all over Europe. ENTSO-E hence devised a specific top-down coordination, both relying on common standards and subsidiarity to take advantage of TSOs’ local expertise and workforce. This organization will be improved to address new challenges but must continue to rely on this combination of top-down lead and decentralized expertise.

32 Not accounting projects that directly connects new generation (another 40%).

33 Other projects enhance grid meshing and thus the overall security of supply, but are discarded from the analysis as in their regard, the initial situation locally shows acceptable risk.

of 148



The TYNDP 2012 enabled ENTSO-E to implement for the first time a cost benefit analysis, articulating market and network studies. ENTSO-E believes that the developed methodology is a good basis in the perspective of the future Energy Infrastructure Package. The valuation of projects and the integrated realization of both the pan-European and regional reports are intended to efficiently support the selection of Projects of Common Interest in the Regional Groups. Visions to 2030 give the framework for the future definition of scenarios and cases bases for ENTSOE datasets and studies. Scenarios in the SOAF are released every year to accommodate every required updates. ENTSO-E now expects stakeholders’ feedback to further develop the methodologies to deliver the TYNDP. The preparation of the TYNDP 2014 has already started!

A major challenge is that the grid development may not be in time if the RES targets are met as planned by 2020. Permit granting procedures are lengthy, and often cause commissioning delays. If energy and climate objectives have to be achieved, it is of upmost importance to smooth the authorization processes. In this respect, ENTSO-E welcomes the proposals made by the European Commission with the draft Energy Infrastructure Package, as there are many positive elements in the permitting section that will facilitate the fast tracking of transmission infrastructure projects including the proposal of a one-stop shop and defined time lines. More thorough analyses are however required so as to ensure the measure can be successfully implemented, particularly in relation to whether the timelines proposed are achievable, and particularly in the context of the public participation process and the potential for legal delays. One must also notice that the supporting schemes are limited to the Project of Common Interest whereas there are many significant national transmission projects that are crucial to the achievement of Europe’s targets for climate change, renewable and market integration.

12 APPENDIX 1: TABLE OF PROJECTS OF PAN EUROPEAN

SIGNIFICANCE The following table shows some synthetic information about the projects mentioned in Chapter 7 of the main document. It gives a synthetic description of each project with some factual information as well as the expected projects impacts and commissioning information.

Project & investment items

A project in the TYNDP package 2012 can cluster several investment items. Every row of the table in appendix 1 to the TYNDP or Regional Investment Plan report corresponds to one investment item. The basic rule for the clustering is that an investment item belongs to a project if this item is required to develop the grid transfer capability increase associated with the project. A project can be limited to one investment item only. An investment item can contribute to two projects; in this case it is depicted only once in the table of projects, in one of the projects (and only referred to in the other project: no technical description, status, etc. are repeated).

Labeling

Projects of pan-European significance are numbered from 1 to 112. Investment items’ labels have the following structure: project_index.investment_index. They are displayed on the projects maps in chapter 7 and in the table of projects below.

Investment items which were present in the TYNDP 2010 have the same index in the TYNDP 2012 package. Indices of investments items which were not present in the TYNDP 2010 start with “Axxx”.

Examples:

• 79.459 designates an investment item, already present in TYNDP 2010 (under the label 459) and contributing to project 79;

• 42.A86 designates a new investment item, not present in TYNDP 2010, contributing to project 42.

Projects develop grid transfer capability across the boundaries as displayed on the following map (see Figure 39). The numbers attached to every boundary on the following map correspond to the projects’ indices relieving the constraints across that boundary:

item; when only one substation is concerned (e.g. refurbishment or installation of some device like a new PST or compensation devices), the two columns are merged. The code of the country concerned is given between brackets.

• Column 5 “Brief technical description” gives a summary of the technical features

(e.g. new line/upgrading of existing circuit, underground cable/OHL, double circuit/single circuit, voltage, route length...).

Columns 6 to 15 sums up the project assessment made for the projects of pan-European significance (see Appendix 3).

• Column 6 “Grid transfer capability increase” shows in MW the order of magnitude, or a range, for the additional grid transfer capability brought by the project.

• Column 7 “Social and economic welfare” can show 5 different displays distinguishing i/ the SEW gained via better accommodation of inter-area transits (background color) and ii/ the SEW gained if the project supplies access to the grid for new generation:

• Column 9 “Improved security of supply” shows 3 levels of concern, and specifies

the area at risk as the case may be: Minor (no specific need)

< 30 M€/y < 30 M€/y and additionally gives direct grid access for new generation 30 to 100 M€/y 30 to 100 M€/y and additionally gives direct grid access for new generation > 100 M€/y

• Column 8 “RES integration” can show 5 different displays distinguishing the direct

connection of RES (< or > 500 MW) and the accommodation of inter-area flows triggered by large amount of RES (> 500 MW):

Neutral Direct access to the grid for less than 500 MW of new RES (medium,

connection) Direct access to the grid for more than 500 MW of new RES (high,

connection) Increasing the capacity between an area with excess of RES generation to

share this with other areas1 (in order to facilitate at least 500 MW of RES penetration)

• Column 16 “present status” describes the progress of the project, with respect to

the main typical phases of grid projects: under consideration / planned / design & permitting / under construction / completed;

• Column 17 “expected commissioning date” gives the year by which the

investment should be commissioned35. 35 This date highly depends of the duration of the permitting process, which TSOs do not master. The date given here is the most likely one, according to present status and to TSO’s experience in conducting projects. The date proposed for reinforcements at a very early stage, the consistency of which is still uncertain, is likely to be further refined by the next TYNDP.

TYNDP 2012 DRAFT PROJECT REPORT IN CONSULTAT European Network of Transmission System Operators

for Electricity

13 APPENDIX 2: KEY CONCEPTS AND DEFINITIONS

13.1 ENTSO-E The European Network of Transmission System Operators for Electricity (ENTSO-E) was established on a voluntary basis on 19 December 2008 and became fully operational on 1 July 20009, in anticipation of the entry in to force of the 3rd Package on 3 March 2011.

Today, 41 TSOs from 34 European countries are members of ENTSO-E. The working structure of the association consists of Working and Regional Groups, coordinated by three Committees (System Development, System Operations and Markets), supervised by a management Board and the Assembly of ENTSO-E, and supported by the Secretariat, the Legal and Regulatory Group, and Expert Groups.

The main purposes of ENTSO-E are: • to pursue the co-operation of the European TSOs both on the pan-European and

regional level; and • to have an active and important role in the European rule setting process in

compliance with EU legislation.

13.2 LEGAL REQUIREMENTS FOR TYNDP (EC 714/2009) The key requirements of the 3rd Package, especially Regulation EC 714/2009, that forms the legislative driver for the “2012 Ten Year Network Development Plan” suite of documents (the “TYNDP 2012 package”) are under:

• Art 8.3 (b) of Regulation

ENTSO-E shall adopt a non-binding Community-wide 10 year network development plan, including a European generation adequacy outlook, every two years.

of 148



• Art 8.4

The European generation adequacy outlook shall cover the overall adequacy of the electricity system to supply current and projected demands for electricity for the next five-year period as well as for the period between five and 15 years from the date of the outlook. The European generation adequacy outlook shall build on national generation adequacy outlooks prepared by each individual transmission operator.

• Art 8.10

ENTSO-E shall adopt and publish a network development plan every two years.

The network development plan shall include the modelling of the integrated network, scenario development, a European generation adequacy outlook and an assessment of the resilience of the system.

The network development plan shall:

• Build on national investment plans, taking into account regional plans, and if appropriate Community aspects of network planning, including the guidelines for trans-European energy networks;

• Build on the reasonable needs of different system users and integrate long-term commitments from investors referred to in Article 8 (tendering procedures), article 13 (ISO) and article 22 (network development) of the Directive;

• Identify investment gaps, notably with respect to cross-border capacities. A review of barriers to the increase of cross-border capacities arising from different approval procedures or practices may be annexed to the network development plan.

13.3 SCENARIOS AND CASES As introduced in TYNDP 2010, § 4.1.2, network planning makes use of two different levels of details to describe the hypotheses, both of which are often referred to as “scenarios” (and thus become sources of confusion):

• A scenario: general economic conditions (economic growth, prices of primary fuels and CO2); general level of load (with underlying uses of electricity, resulting for example in typical shape of load curve and sensitivity to temperature); generation fleet (number of units of every type, and respective size), network consistency;

• A case: i.e. a particular situation that may occur within the framework of a scenario, featuring:

o one specific point-in-time (e.g. winter / summer, peak hours / low load conditions),

of 148



o a particular realisation of random phenomena, generally linked to climatic conditions (such as wind conditions, hydro inflows, temperature, etc.) oravailability of plants (forced and planned);

o the corresponding merit-order dispatch of all generating units resulting from all above assumptions.

A scenario can thus be described quite synthetically, and debated. Cases correspond however to the relevant situations that network planers study to assess likely investments needs and the efficiency of any measure to solve them.

13.4 INVESTMENT NEEDS TYPOLOGY As introduced in TYNDP 2010, § 5, Investment needs are every concern ahead on the regional grid and of European significance, and which are likely to trigger extra-high voltage grid investment in order to restore the grid ability to fulfil the duties and services expected from this infrastructure.

The investment needs are sorted in the following categories:

• Demand growth: large cities or regions, where the security of supply can be at risk despite a sufficient generation capacity overall, i.e.: at risk specifically because of lacking transmission means.

• Future generation evacuation: places where new generation facilities asked (or are likely to ask) for connection, be they large power plants and/or distributed generation, RES or not, and the existing network does not assure an adequate evacuation and integration into the system. In the present TYNDP 2012 package, RES and conventional generation have been distinguished to provide a clearer picture.

• Existing generation evacuation: places where existing generation cannot be evacuated reliably in all situations because of a change in surrounding power flow patterns.

• Generation decommissioning: places where large power plants are decommissioned, modifying the surrounding power flow patterns, or causing local voltage level concerns.

• Insufficient cross-border capacity, i.e. structural market congestion between price zones 29. Two subset of structural congestion are specifically identified:

o Change in exchange patterns: grid section, the transfer capability of which may appear no more appropriate to accommodate power exchanges, that is new (or recent) congestion.

of 148



o Isolated systems to be connected: typically islands to be connected to the mainland.

• Reliable grid operation: substations, where risks of current and voltage limits violation require upgrade of HV equipment to withstand now likely high short circuit currents, to manage reactive power issues, transient stability issues, etc. in steady state and fault situations.

• Ageing/obsolescence of existing network equipment: asset requiring replacement or heavy refurbishment in order to maintain the grid transfer capability at its present standards, but possibly address new environmental concerns (e.g. higher standards against climatic conditions).

Isolation of systems, demand growth, commissioning and decommissioning of generation, ageing/obsolescence of existing network equipment are primary drivers, i.e. exogenous causes for grid development. Other needs (change in exchange patterns, existing generation evacuation, insufficient cross-border capacity, reliable grid operation) are assessed only once the primary drivers are set.

13.5 INVESTMENT ITEMS, PROJECTS, PROJECTS OF PAN-EUROPEAN

SIGNIFICANCE A Project in the TYNDP package 2012 can cluster several Investment items. Every row of the table in appendix 1 to the TYNDP or Regional Investment Plan report corresponds to one investment item. The basic rule for the clustering is that an investment item belongs to a project if this item is required to develop the grid transfer capability increase associated to the project.

A project can be limited to one investment item only.

An investment item can contribute to two projects. In this case it is depicted only once, in one of the projects; and only referred to in the other project (no technical description, status, etc. are repeated).

A Project of Pan-European Significance is a set of Extra High Voltage assets, matching the following criteria:

• The main equipment is at least 220 kV if it is an overhead line AC or at least 150 kV otherwise and is, at least partially, located in one of the 32 countries represented in TYNDP.

• Altogether, these assets contribute to a grid transfer capability increase across a network boundary within the ENTSO-E interconnected network (e.g. additional NTC

of 148



between two market areas) or at its borders (i.e. increasing the import and/or export capability of ENTSO-E countries vis-à-vis others).

• An estimate of the abovementioned grid transfer capability increase is explicitly provided in MW in the application.

• The grid transfer capability increase meets least one of the following minimums: o At least 500 MW of additional NTC; or o Connecting or securing output of at least 1 GW/1000 km² of generation; or o Securing load growth for at least 10 years for an area representing

consumption greater than 3 TWh/yr. NB:

• Regional Investment Plans and National Development Plans can complement the development perspective with respect to other projects than Projects of Pan-European Significance.

• Projects of pan-European significance are candidate projects for the Project of Common Interest foreseen by the future EIP.

13.6 BOUNDARIES, BULK POWER FLOWS, GRID TRANSFER CAPABILITY According to the “Guideline for the assessment of impacts of projects” (see Appendix 3) a Boundary is one section of the grid between one area and another (price zone, area within a country or a TSO), or several sections of the grid sharing the same concern, across which it appears relevant for TSOs to assess grid transfer capability values (in order to auction capacity, to advertise the possibility of new generation connection upstream, or to communicate on securing load growth for several years downstream). A boundary, across which a grid transfer capability assessed, is hence oriented, i.e. relates to a specific direction of power flows (for an international border A-B, one boundary A>B and another boundary B>A can be defined. The PL>DE+CZ+SK is a boundary; CZ>PL is another).

A boundary may remain stable (border between states or price zones), or vary from one horizon or scenario to another. It may be internal to a country or a price zone.

A Bulk power flow is the typical power flow triggering grid development across a boundary.

The Grid Transfer Capability (GTC) is the ability of the grid to transport electricity across a boundary, i.e from one area (price zone, area within a country or a TSO) to another. It depends on the considered state of consumption, generation and exchange, as well as the topology and availability of the grid, and account for safety rules (such as the N-1 rule). It is expressed in MW, and represents maximum transfer capabilities between two areas calculated under certain conditions.

of 148



The Grid Transfer Capability is oriented, which means that across a boundary, there may be two different values.

The Grid Transfer Capability compares rather directly with the NTC when the boundary separates prices zones if the transmission reliability margin is neglected; or, roughly again, with the amount of generation or load that can be accommodated.

14 APPENDIX 3: GUIDELINES FOR GRID DEVELOPMENT NB: the Guidelines for Grid Development are general guidelines that apply in particular but not only for TYNDP underlying studies. It is published by ENTSO-E and as independent document. It is recalled here in appendix to the TYNDP 2012.

14.1 INTRODUCTION AND SCOPE

14.1.1 TRANSMISSION SYSTEM PLANNING The move to a more diverse power generation portfolio due to the rapid development of renewable energy sources and the liberalization of the European market have resulted in more and more interdependent power flows across Europe, with large and correlated variations. Therefore, transmission systems need to be designed looking beyond the traditional TSO boundaries, towards regional and European solutions. Thus, close co-operation of member companies responsible for the future development of the European transmission system is required to achieve a coherent and coordinated planning The main objective of transmission system planning is to ensure, with respect to mid and long term horizons, the development of an adequate transmission system which:

of 148



The planning criteria to which transmission systems are designed are generally specified in transmission planning documents. Such criteria have been developed for application by individual TSOs taking into account the above factors and specific conditions to the network to which they relate. The planning standards inherited from individual TSOs are technically very similar, but clarity and common assessment criteria for reinforcements at a pan-european level are required. In order to optimize the efforts of each TSO involved and comply with a coherent pan-european Ten Year Network Development Plan, suitable methodologies have been adopted on future development projects, and common investment assessments have been developed. This document gives an overview of the common methodologies adopted by ENTSO-E.

14.1.2 SCOPE OF THE DOCUMENT This document describes the common principles and procedures to be used by TSOs within ENTSO-E when elaborating Regional Investment Plans and the Community-wide Ten Year Network Development Plan (TYNDP), as ratified by EC Regulation 714/2009 of the 3rd Legislative Package. Typically, development transmission projects fall into three categories as follows:

• Those that only affect transfer capabilities between individual TSOs. These projects will be developed according to the criteria in this document.

• Those that influence both transfer capabilities between TSOs and the internal capability of a TSO’s network. These projects will meet the criteria of this document and of the affected TSO’s internal standard.

• Those that impact only on an internal national network and neither influence interconnection capability or are of European interest. These are not in the scope of this code, and are developed according to the TSO’s internal standard.

14.1.3 CONTENT OF THE DOCUMENT Transmission system development focuses on the long-term preparation and scheduling of reinforcements and extensions to the existing transmission grid. This document describes each phase of the development planning process and the planning criteria adopted by ENTSO-E.

The first phase of the planning process consists of the definition of scenarios, which represent a coherent, comprehensive and internally consistent description of a plausible future. The aim of scenario analysis is to depict uncertainties on future system developments on both the production and demand sides. In order to incorporate these uncertainties in the planning process, a number of planning cases are built, taking into account forecasted future demand level and location, dispatch and location of generating units, power exchange patterns, as well as planned transmission assets. This phase is detailed in Chapter 2.

The analyses and “network stress tests” performed on each planning case in order to identify reinforcement needs follow specific technical planning criteria developed by ENTSO-E on the basis of long term engineering practice. The criteria cover both the kind of contingencies36 chosen as “proxies” for hundreds of other events that could happen to the grid, and the adequacy criteria relevant for assessing overall behavior of the transmission system. The behavior of the grid when simulating the contingencies indicates the “health” and robustness of the system. A power system that fails one of these tests is considered “unhealthy” and steps must be taken so that the system will respond successfully under the tested conditions. Several planning cases are thus assessed in order to identify how robust reinforcement is. This process is developed in Chapter 3.

Finally, the last step of planning process is the identification of projects necessary to restore the “health” of the system and their assessment. Chapter 4 thus describes the procedure and multi-criteria framework adopted for project assessment.

36 A contingency is the loss of one or several elements of the power transmission system

The impact assessment criteria adopted in this document reflect each transmission project’s added value for society, in terms of increased capacity for trading of energy and balancing services between price zones, RES integration and security of supply. The indicators also reflect the effects of the project in terms of costs and environmental impact.

The whole process is continuingly evolving, and it is the intention that this document will be reviewed periodically in line with prudent planning practice and further editions of the TYNDP.

14.2 PLANNING SCENARIOS Planning scenarios are defined to represent future environments. The essence of scenario analysis is to come up with plausible pictures of the future. Scenarios are means to approach the uncertainties and the interaction between these uncertainties.

Planning studies require a set of assumptions as inputs. In order to provide planning studies with the required data, scenarios are defined to represent technical and economic conditions by considering a demand forecast, a generation mix and a set of exchange patterns with systems outside the studied region.

The following are the more important issues that have to be taken into account when building detailed cases for planning studies:

14.2.1 DEFINITIONS D.1. Planning scenario: It is a coherent, comprehensive and internally consistent

description of a plausible future (in general composed of several time horizons) built on the imagined interaction of economic key parameters (including economic growth, fuel prices, CO2 prices, etc.). A planning scenario is characterized by a generation portfolio (power installation forecast, type of generation, etc.), a demand forecast (impact of efficiency measures, rate of growth, shape of demand curve, etc.), and exchange patterns with the systems outside the studied region. A scenario may be based on trends (bottom-up scenarios) or energy policy targets (top-down scenarios). A scenario is represented by several cases.

D.2. Planning case: A planning case represents a particular situation that may occur within the framework of a planning scenario, featuring:

� one specific point-in-time (e.g. winter / summer, peak hours / low demand conditions, year), with its corresponding demand and environmental conditions;

� a particular realisation of random phenomena, generally linked to climatic conditions (such as wind conditions, hydro inflows, temperature, etc.) or availability of plants (forced and planned);

� the corresponding dispatch (coming from a market simulator or a merit order) of all generating units (and international flows);

� detailed location of generation and demand; � power exchange forecasts with regions neighbour to the studied region;

of 148



� and assumption on grid development. D.3. Representative planning scenarios: Scenarios defined from EU objectives

and/or from trends by ENTSO-E and TSOs, taking into account regional and national particularities.

D.4. Representative planning case: Representative planning cases are those that are considered relevant to represent a planning scenario in order to assess the need of grid reinforcement and/or grid optimization. They are defined based on criticality and/or frequency of occurrence.

D.5. Merit order: In cases where multiple generation sources are available, generating facilities and individual generating units within those facilities are ranked according to their availability and their variable cost of generation (supposing a perfect market). This ranking is referred to as merit order rank. Non dispatchable units (such as wind and PV), then generation facilities with the lowest prices, are used first to balance the demand.

14.2.2 COMMON CRITERIA C.1. Representative planning scenarios are to be used

C.2. Each scenario is assessed through its representative planning cases: Each selected scenario is assessed by analyzing the cases that represent it. These cases are defined (considering the issues mentioned in C.4) by the TSOs involved in each study, taking into account regional and national particularities.

C.3. Time horizons: At least two time horizons, with a 5 years span, will be considered when building representative cases:

� Mid term horizon (typically 5 years). � Long term horizon (typically 10 years).

C.4. When building representative planning cases the following issues should be considered: � Estimated main power exchanges with external systems. � Seasonal variation (e.g. winter/summer). � Demand variation (e.g. peak/valley). � Weather variation (e.g. wind, temperature, precipitations, sun, tides�).

C.5. Planned transmission system: All the transmission assets that are included in existing plans will be dealt with in the corresponding case taking into account the forecasted commissioning and decommission dates (other cases may be used, see R2).

14.2.3 BEST PRACTICE R.1. Representative cases may be established using results of market studies. R.2. Other cases different from representative cases can be investigated if

needed. These other cases might be defined in a multi-case or probabilistic analysis. This approach aims to assess risks of grid operation throughout the year or several years and to determine the uncertainties that characterise it. The objective is to cover many transmission system states in order to:

� Detect ‘critical system states’ that are not detected by other means.

of 148



� Estimate the probability of occurrence of each case assessed, facilitating the priority evaluation of the needed new assets.

For more information about multi-case analysis, see R.8.

R.3. Planned transmission system expansion projects. The uncertainty in the commissioning date of some future assets could require a conservative approach when building the cases, taking into account:

� State of permitting procedure (permits already obtained and permits that are pending).

� Existence of local objection to the construction of the infrastructure.

� Manufacturing and constructing deadlines.

A case without one or some reinforcements foreseen, as well as cases including less conservative approaches, could be analysed.

R.4 Obsolete or old assets. To check the actual role of a grid element, and thus compare different strategies (e.g. refurbishment of the asset vs. dismantling and building a new asset), it may be considered as absent in the planning case.

14.3 TECHNICAL CRITERIA FOR PLANNING Technical methods and criteria are defined to be used when assessing the planning scenarios, in order to identify future problems and determine the required development of the transmission grid.

The general methodology implies:

• +�$#� � %6�$��

� Investigation of base case topology (all network elements available).

� Different type of events (failures of network elements, loss of generation, �) are considered depending on their probability of occurrence.

• &9 %5 $"��""��!�5% ��

� Evaluation of consequences by checking the main technical indicators:

- Cascade tripping.

- Thermal limits.

- Voltages.

- Loss of demand

- Loss of generation

- Short circuit levels

- Stability conditions.

- Angular difference.

of 148



� Acceptable consequences can depend on the probability of occurrence of the event.

Currently deterministic criteria are used in the planning of the grid.

14.3.1 DEFINITIONS

#� � Base Case for network analysis. Data used for analysis are mainly determined by the planning cases. For any relevant point in time, the expected state of the whole system, “with all network equipment available”, forms the basis for the analysis (“Base case analysis”).

#�� Contingencies. A contingency is the loss of one or several elements of the power transmission system. A differentiation is made between normal, rare and out-of-range contingencies. The wide range of climatic conditions and the size and strength of different networks within ENTSO-E mean that the frequency and consequences of contingencies vary among TSOs. As a result, the definitions of normal and rare contingencies can differ between TSOs. The standard allows for some variation in the categorisation of contingencies, based on their likelihood and impact within a specific TSO network.

� A normal contingency is the (not unusual) loss of one of the following elements:

- Generator.

- Transmission circuit (overhead, underground or mixed).

- A single transmission transformer or two transformers connected to the same bay.

- Shunt device (i.e. capacitors, reactors, ...).

- Single DC circuit.

- Network equipment for load flow control (phase shifter, FACTS, �).

- A line with two or more circuits on the same towers if a TSO considers this appropriate and includes this contingency in its normal system planning

� A rare contingency is the (unusual) loss of one of the following elements:

- A line with two or more circuits on the same towers if a TSO considers this appropriate and does not include this contingency in its normal system planning

- A single busbar.

- A common mode failure with the loss of more than one generating unit or plant.

- A common mode failure with the loss of more than one DC link.

� An out-of-range contingency includes the (very unusual) loss of one of the following:

- Two lines independently and simultaneously.

- A total substation with more than one busbar.

- Loss of more than one generation unit independently.

of 148



#�� N-1 criterion for grid planning. The N-1 security criterion is satisfied if the network is within acceptable limits for expected transmission and supply situations as defined by the planning cases, following a temporary (or permanent) outage of one of the elements of the normal contingency list (see D7 and chapter 3.2.2 ).

14.3.2 COMMON CRITERIA 3.2.1 Studies to be performed

�� Load flow analysis

• Examination of normal contingencies. N-1 criterion is systematically assessed taking into account each single normal contingency of one of the elements mentioned above.

Examination of rare contingencies. Rare contingencies are assessed in order to prevent serious interruption of supply within a wide-spread area. This kind of assessment is done for specific cases based on the probability of occurrence and/or based on the severity of the consequences.

Examination of out-of-range contingencies. Out-of-range contingencies are very rarely assessed. Their consequences are minimised through Defence Plans.

�� Short circuit analysis. Maximum and minimum symmetrical and single-phase short-circuit currents are evaluated according to the IEC 60 909, in every bus of the transmission network

�� Voltage collapse. Analysis of cases with a further demand increase by a certain percentage above the peak demand value is undertaken. The resulting voltage profile, reactive power reserves, and transformer tap positions are calculated.

�� Stability analysis. Transient simulations and other detailed analysis oriented to identifying possible instability shall be performed only in cases where problems with stability can be expected, based on TSO knowledge.

3.2.2 Criteria for assessing consequences

�� Steady state criteria

• Cascade tripping. A single contingency must not result in any cascade tripping that may lead to a serious interruption of supply within a wide-spread area (e.g. further tripping due to system protection schemes after the tripping of the primarily failed element).

• Maximum permissible thermal load. The base case and the case of failure must not result in an excess of the permitted rating of the network equipment. Taking into account duration, short term overload capability can be considered, but only assuming that the overloads can be eliminated by operational countermeasures within the defined time interval, and do not cause a threat to safe operation.

• Maximum and minimum voltage levels. The base case and the case of

of 148



failure shall not result in a voltage collapse, nor in a permanent shortfall of the minimum voltage level of the transmission grid, which are needed to ensure acceptable voltage levels in the sub-transmission grid. The base case and the case of failure shall not result in an excess of the maximum admissible voltage level of the transmission grids defined by equipment ratings and national regulation, taking into account duration.

�� Maximum loss of load or generation should not exceed the power available in primary regulation reserve for each synchronous region.

�� Short circuit criteria. The rating of equipment shall not be exceeded to be able to withstand both the initial symmetrical and single-phase short-circuit current (e.g. the make rating) when energising on to a fault and the short circuit current at the point of arc extinction (e.g. the break rating). Minimum short-circuit currents must be assessed in particular in busbars where a HVDC installation is connected in order to check that it works properly.

�� Voltage collapse criteria. The reactive power output of generators and compensation equipment in the area should not exceed their continuous rating, taking into account transformer tap ranges...

�� Stability criteria. Taking into account the definitions and classifications of stability phenomena37, the objective of stability analysis is the rotor angle stability, frequency stability and voltage stability in case of normal contingencies (see section 3.1), i.e. incidents which are specifically foreseen in the planning and operation of the system. For the assessment of normal contingencies a successful fault clearing by the primary protection system is implied.

• Transient stability. Any 3-phase short circuits successfully cleared by the primary protection system in service (or forecasted) shall not result in the loss of the rotor angle and the disconnection of the generation unit (unless the protection scheme requires the disconnection of a generation unit from the grid).�

• Reinforcement of overhead circuits to increase their capacity (e.g. increased distance to ground, replacing of circuits).

• Duplication of cables to increase rating.

• Replacing of network equipment or reinforcement of substations (e.g. based on short-circuit rating).

• Extension of substations and construction of new ones.

• Installation of reactive-power compensation equipment (e.g. capacitor banks).

• Addition of network equipment to control the active power flow (e.g. phase shifter, series compensation devices).

• Additional transformer capacities.

• Construction of new circuits (overhead and cable).

14.3.3 BEST PRACTICE R5. Load flow analysis. Failures combined with maintenance. Certain

combinations of possible failures and non-availabilities of transmission elements may be considered in some occasions. Maintenance related non-availability of one element combined with a failure of another one may be assessed. Such investigations are done by the TSO based on the probability of occurrence and/or based on the severity of the consequences, and are of particular relevance for network equipment that may be unavailable for a considerable period of time due to a failure, maintenance, overhaul (for instance cables or transformers) or during major constructions.

R6. Steady state analysis. Acceptable consequences depend on the type of event that is assessed. In the case of rare contingencies, acceptable consequences can be defined regarding the scale of the incident, and include loss of demand. Angular differences should be assessed to ensure that circuit breakers can re-close without imposing unacceptable step changes on local generators.

R7. Voltage Collapse analysis: The aim of voltage collapse analysis is to give some confidence that there is sufficient margin to the point of system collapse in the analysed case to allow for some uncertainty in future levels of demand and generation.

R8. Multi-case analysis. The decisions in ENTSO-E system planning studies are generally based on deterministic analysis, in which several representative planning cases are taken into account. Additionally, studies based on a probabilistic approach may be carried out. This approach aims to assess the likelihood of risks of grid operation throughout the year, and to determine the uncertainties that characterise it. The objective is to cover many transmission system states across the entire year taking into account many cases. Thus it is possible to:

• Detect 'critical system states' that are not detected by other means.

• Estimate the probability of occurrence of each case assessed, facilitating the priority evaluation of the needed new assets.

The basic idea of probabilistic methods is based on creating multiple cases depending on the variation of certain variables (that are uncertain). Many uncertainties can lead to building multiple cases: demand, generation availability, renewable production, exchange patterns, network components availability, etc. The general method consists of the following steps:

of 148



• Definition of variables to be considered (for example: demand).

• Definition of values to be considered for each of the variables and estimation of the probability of occurrence. In the case where a variable with many possible values is considered (for example: network unavailability), the amount of different possible combinations could recommend the use of a random approach method.

• Building of all the planning cases needed. The amount of cases will depend on the amount of variables and the amount of different values of each of them.

• Each case is analysed separately.

• Assessment of the results. Depending on the amount of cases, a probabilistic approach could be needed to assess the results. A priority list of actions could result from this assessment.

If the variables used to build multiple cases are estimated in a pure probabilistic way a statistical tool is needed for the assessment. In this case, besides helping to make a priority list of the actions needed in a development plan and identifying critical cases not known to be critical in advance, the probabilistic approach allows forecasting the Energy Not Supplied (ENS) and Loss Of Load Expectation (LOLE) and congestion costs. The probabilistic assessment of other variables, like short-circuit current, could also be very useful for planning decisions.

14.4 PROJECT ASSESSMENT The goal of project assessment is to characterise the impact of transmission projects, both in terms of added value for society (increase of capacity for trading of energy and balancing services between price zones, RES integration, increased security of supply, �) as well as in terms of costs.

It is important to note that ranking of projects is out of the scope of this document.

14.4.1 ASSESSMENT FRAMEWORK The assessment framework is a multi-criteria one. The criteria set out in this document have been selected on the following basis:

- They will enable an appreciation of project benefits in terms of EU network objectives:

• ensure the development of a single European grid to permit the 20-20-20 objectives;

• guarantee security of supply; ��

• complete the internal energy market, especially through a contribution to increased social welfare ;

• ensure technical resilience of the system, as expressed in the Green paper on infrastructure networks39, the European Regulation 2009-714, the European Infrastructure Package40 and further detailed during the consultation on the TYNDP 201041 and the Stakeholder Workshop on the assessment of projects of European interest.

- They will give a measure of project costs and feasibility (especially environmental and social impact).

- The indicators used will be as simple and robust as possible. This will lead to simplified methodologies for some indicators.

The figure below shows the main categories that group the indicators used to assess the impact of projects.

FIGURE 42: MAIN CATEGORIES OF THE PROJECT ASSESSMENT

Some investments or projects will provide all the benefit categories, whereas other projects will only contribute significantly to one or two of them.

Other impacts, such as benefits for competition, more flexible operation etc� also exist. These are more difficult to model, and will not be explicitely taken into account at this stage.

This assessment has to be done independently for each evaluated scenario.

The Benefit Categories42 are defined as follows:

These Guidelines are unable to well-define any metric solely relating to facilitation of competition. If transmission reinforcement has minimised congestion, that has facilitated competition in generation to the greatest extent possible. 43 Adequacy measures the ability of a power system to supply demand in full, at the current state of network availability; the power system can be said to be in an N-0 state. Security measures the ability of a power system to meet demand in full, and to continue to do so under all credible contingencies of single transmission faults; such a system is said to be N-1 secure.

FIGURE 43: EXAMPLE OF ASSESSMENT SUMMARY TABLE

14.4.2 COST AND ENVIRONMENTAL LIABILITY ASSESSMENT

14.4.2.1 C.1. TOTAL PROJECT EXPENDITURE

For each project costs have to be estimated. Within ENTSO-E, project expenditures are strongly dependent on local conditions and therefore differing. Consequently, project costs may be calculated by using local standard-cost.

Indicative colors are assigned as follows: Light green: Higher than 1000 M€

Green: Between 300 M€ and 1000 M€

Dark green: Lower than 300 M€

14.4.2.2 S.1. SOCIAL AND ENVIRONMENTAL IMPACT

Social and Environmental impact characterises the project impact as perceived by the local population, and as such, gives a measure of probability that the project will be built at the planned commissioning date. Impact on nature (biodiversity�), on human activity and social compatibility (visual impact �) are analysed in order to identify the impact on the planned commissioning date. Early assessment of social and environmental impact will help increasing social compatibility and successful licensing. The indication is found through an expert assessment, if possible supported by preliminary environmental studies. Indicative colors are assigned as follows:

Light green: the probability of carrying out a project at the planned commissioning date is considered as high (no protected or dense urban area is affected, there are no known former infrastructure conflicts in the area, the visual impact is perceived as low).

Amber: the probability of carrying out a project at the planned commissioning date is considered as realistic but exposed to uncertainty (protected or urban area may be affected in a limited way, visual impact is perceived as moderate).

1. Red: the probability of carrying out a project at the planned commissioning date is considered as low (visual impact is perceived as high, protected or urban area may

be affected, there have been former conflicts in the area).

14.4.3 BENEFIT ASSESSMENT

14.4.3.1 GEOGRAPHICAL SCOPE OF THE ANALYSIS

The geographical scope of the analysis is an ENTSO-E Region as a minimum. If necessary, it can be extended to surrounding countries.

14.4.3.2 BENEFIT ANALYSIS

The evaluation of the effects may be performed using both market studies and network analysis, including expert assessment.

Market based assessment gives a detailed assessment of generation and consumption profile, using a simplified representation of the grid. Market studies performing hourly analysis throughout the year have the advantage of clearly highlighting the structural rather than incidental bottlenecks.

14.4.3.4 METHODOLOGY FOR EACH BENEFIT INDICATOR

B1. SECURITY OF SUPPLY

Security of Supply is the ability of a power system to provide an adequate and secure supply of electricity in normal conditions, in a specific area. The improvement of security of supply is assessed under contingencies defined in Chapter 3. The assessment shall be focused on a delimited geographical area. The boundary of the area may consist of the nodes of a quasi-radial sub-system or semi-isolated area (e.g. with a single 400 kV injection). The system is at risk if the given contingency criteria are not fulfilled during 10 years following its commissioning.

As an example, a simple indicator is shown in the figure below.

FIGURE 44: METHODOLOGY TO COMPUTE INDICATORS

��

� �� !"#$%� !�#$�� !"#�$%� !�#�$��

Indicative colors are assigned as follows :

• Light green: the project will not improve security of supply, i.e. for supplying electricity for normal contingencies, during the ten years following its commissioning

• Green: the project improves the security of supply under normal contingencies as defined in chapter 2 during the ten years following its commissioning.

••

Dark green: the project additionally improves the security of supply under rare contingencies as defined in Chapter 2 during the ten years following its commissioning.

14.4.3.5 ��

The social and economic welfare benefit is calculated from the reduction in total generation costs46 associated with the GTC variation that the project allows. By removing network bottlenecks that restrict the access of generation to the full European market, a project can facilitate increased competition between generators, reducing the cost of electricity to end consumers. Similarly, a project can contribute to reduced costs by providing a direct system connection to new, relatively low cost, generation.

This cost reduction is calculated from an economic assessment to determine the optimum cost of total generation dispatch, with and without the project. The benefit for each case is calculated from:

Benefit (for each hour) = Generation dispatch costs without the project – Generation dispatch costs with the project. The “social and economic welfare” is expressed by the socio-economic benefit. This benefit is measured in €.

The total benefit for the horizon is calculated by summing the benefit for all the hours of the year.

Indicative colours are assigned as follows47:

• Light green : the project has an annual benefit < € 30 million

Striped light green : the project has an annual benefit < € 30 million and, additionally, includes direct connection of new generation

• Green: the project has an annual benefit between€ 30 and € 100 million

• Striped green : the project has an annual benefit between€ 30 and € 100 million and, additionally, includes direct connection of new generation

• Dark green: the project has an annual benefit > or = to € 100 million

14.4.3.6 ��

RES integration is facilitated by:

46 Since electricity demand is considered inelastic, net decrease in generation costs is a relevant measure for social benefit. Only variable costs are taken into account (no investment costs or subsidies are considered).

47 Stripes indicate that the project is triggered by direct connection of generation.

48 Calculating impact of RES in absolute numbers (MW) facilitates the comparison of projects all over Europe when looking at the sole aspect of RES integration. Relative numbers (i. e the contribution of a project compared to the objectives of the NREA) can easily be calculated ex post for analysis at a national level.

1. Connection to the main system

2. Increasing the GTC between an area with excess of RES generation to share this with other areas in order to facilitate higher level of RES penetration

For point 1, RES integration is measured by amount of MW connected in a given area. For point 2, the border for calculating the GTC is to be placed in a way that divides an area with an excess of RES from an area where that RES generation can be consumed. The RES integration benefit is then calculated in MW through the calculation of the increase in GTC provided by a project.

The analysis process consists of taking two cases, one with and one without the project, and for each case increasing the renewable production in the excess generation area until the criteria of chapter 2 is not fulfilled. The RES benefit is calculated by the difference between the values of GTC obtained for both cases.

Market studies may also be used to calculate RES energy that is integrated in the model in the area with excess of RES, taking into account RES production time profiles.

Indicative colours are assigned as follows49:

• White: the project has a neutral effect on the capability of integrating RES

• Striped green: the project allows direct connection of less than 500 MW RES production

• Striped dark green: the project allows direct connection of more than 500 MW RES production

• Dark green: This project allows an increase of capacity between an area with excess of RES generation to share this with other areas50 (in order to facilitate at least 500 MW of RES penetration)

The energy efficiency benefit of a project is measured through the reduction of thermal losses (MW) in the system51. The losses in the system are quantified for each case, with and without the project. The total benefit is then calculated as the difference between both values. 49 Stripes indicate that the project is triggered by direct connection of generation.

50 Direct access can be also achieved incidentally.

51 It should be noted that an increase in losses means a higher utilisation of the grid, e.g due to additional cross border exchanges or RES infeed.

15 APPENDIX 4: SOCIAL ACCEPTANCE OF PROJECTS

15.1 BETTER STREAMLINED AUTHORIZATION PROCESSES FOR POWER

LINES WOULD SECURE EU ENERGY POLICY GOALS Effective electricity infrastructure is fundamental for guaranteeing EU security of energy supply. Ensuring the development of the grid is necessary to permit the achievement of the EU’s renewable energy and climate change objectives and for completing the internal energy market. These are challenges for the governments of all member states. As detailed in the TYNDP 2010 report, the development of electricity infrastructure is thus of crucial national and European importance to make Europe meet these challenges.

Yet, many electricity infrastructure projects face long and complex procedures in the authorization phase, across the different European countries. For the most part, these concerns arise irrespective of whether the developments are domestic or cross-border lines. The procedures for Extra High Voltage assets prove often longer and more complex than for any other infrastructure (roads, railways, gas-pipes).

Authorization processes for power lines must be streamlined so as to ensure both fulfillment of legal obligations as for other infrastructure and industrial facilities, and the timely commissioning of the transmissions assets which would help the EU meet their energy policy goals.

15.2 THE TYNDP 2010 SUMMED UP THE KEY CONCERNS REGARDING

SOCIAL ACCEPTANCE OF TRANSMISSION PROJECTS The TYNDP 2010 report explains all concerns with respect to long and complex, possibly redundant, and long authorization procedures for power lines, summed up hereafter:

• Unharmonised legislation between countries and even between regions within the same country;

• Lack of reasonable and concrete time limits for issuing the approvals;

• High number of approval agencies that share different interests;

• Balance between the necessity for grid development and environmental interests;

• Different permitting procedures for different technologies (e.g. line/ substations, OHL/Cable) esp. with respect to EIA;

of 148



• Lack of stakeholder (including political) support for projects;

• Lack of social acceptance of projects:

o Lack of public understanding with respect to the requirement for the project –consideration proposals are mere transit/commercial lines without public benefit;

o doubts about the project necessity, environmental impact, EMF, property devaluation;

o existence of alternative solutions even if are more expensive and technical complicated.

15.3 THE DRAFT ENERGY INFRASTRUCTURE PACKAGE SETS PROMISING

LEADS FOR IMPROVING SOCIAL ACCEPTANCE OF TRANSMISSION

PROJECTS ENTSO-E released the TYNDP 2010 early 2010 so as to raise concerns about the urgency to solve structural problems with respect to power grid development. In late 2010, the EC launched the drafting of new legislation to foster the development of key energy network assets. The so-called Energy Infrastructure Package, proposes in particular a whole range of measures to improve social acceptance of projects:

• Priority status for permit granting Projects of Common Interest at national level

• One competent national authority taking the final decision

• Clear time limits for decisions by competent Authority:

o pre application (max 2 years)

o statutory granting procedure (max 1 year)

• In the case of Substantive delays – a European Coordinator to be appointed

• Increase of transparency, efficiency and reduction of complexity.

• Member States within 9 months after decision to take measures to streamline decision-making process. Appointment CA within 6 months.

• Member States to provide joint procedures with respect to the environmental assessment.

of 148



ENTSO-E welcomes these proposals, as there are many positive elements in the permitting section which will facilitate the fast tracking of transmission infrastructure projects including the proposal on one stop shop and defined time lines.

More thorough analyses are however required so as to ensure the measure can be successfully implemented, in particular in relation to whether the timelines proposed are achievable particularly in the context of the public participation process and the potential for legal delays.

One must also notice that the supporting schemes are limited to the so-called Project of Common Interest (PCIs) whereas there are many significant national transmission projects which are crucial to the achievement of Europe’s targets for climate change, renewable and market integration.

16 APPENDIX 5: TECHNOLOGIES – OUTLOOK, PERSPECTIVES

16.1 INTRODUCTION As we can observe changes in electricity markets requirements, power demand shape, power sources distribution or other external constraints, Transmission System Operators need to anticipate their future needs and participate in an active way in the research and development of new technologies. For the same reasons, TSOs consider permanently the panel of available technologies and strive to make the best use of them, including technologies considered as unconventional rather than new, for their little use does not offer the very large experience shared on conventional technologies.

The technologies employed to date in the transmission grids are efficient, reliable, well engineered and are widely available techniques for transferring energy in high-voltage grids.

The evolution of technologies depends on several factors. As a matter of fact, documents such as the European “SmartGrids Vision” formulate a demand pull on technology, which is fully experienced by TSOs through their deep involvement in R&D projects. Liberalization of the European electricity market, massive integration of renewable generation in the system, as well as environmental, social and economic constraints, constitute the major drivers of this demand pull.

On the other hand, power industry offers a variety of new, emerging technologies for the evolution of power systems, as observed in many available studies and recently compiled by the “Realisegrid” European co-funded project.

Of course, the present appendix is not bound to give a comprehensive description of all the research done about grid operation and development. Moreover, as some projects are considered as demonstration projects rather than network development projects, they do not appear at the TYNDP level.

Therefore, the reader is invited to refer to the ENTSO-E R&D Plan, which describes a plan of around €560 million over ten years, split into €270 million for research and €290 million for demonstrations.

Priority research fields, which are included in the R&D plan and subsequently in R&D projects managed by ENTSO-E members – and therefore monitored by ENTSO-E – include the following:

• architecture and planning tools for the pan-European network,

• tools to prove the efficiency of technology aimed at increasing both the flexibility and the security of the operation of transmission systems,

of 148



• new tools based on simulation techniques that will give rise to new market design options.

In this respect, this appendix only presents a brief illustration of the researched fields, to illustrate how transmission projects presented in Chapter “Foreseen Investments on the European Grid” indeed take advantage of the best available technologies to meet present and future grid development challenges.

In the present selection of innovative and unconventional technologies, each technology has its own advantages and drawbacks, which have to be considered and assessed in the context of a given project. As ENTSO-E considers it very difficult and delicate to assess a technology in a global way and apart from given local needs and constraints, the current document does not provide any quantitative assessment or any comparison between examined technologies.

Indeed, each project is different and therefore inherits different levels of benefits from new technologies. Although some new technologies have been granted a lot of publicity, there is no universal solution for transmission networks so far.

Each project has to be studied with its own characteristics and assessment of the best fitted technologies.

16.2 OVERVIEW OF AVAILABLE OR PROMISING TECHNOLOGIES TODAY This section deals with novel techniques as well as with unconventional techniques, i.e. known technologies that have not been widely used for various reasons. Basically technologies can be sorted into four categories depending on their maturity:

• Some are mature, even though they might not be largely implemented, i.e. they have already proved their general applicability, have been fully developed, tested, their operation within the existing meshed grid proved reliable and introducing new items is not a technological challenge. DC connections between synchronous and asynchronous areas, Phase Shifting Transformers (PSTs) are examples of such mature technologies.

• Some are in large scale testing phase, i.e. they have been fully developed (laboratory devices work) but their insertion into the existing meshed grid is still being, or to be, tested, in order to check they can be reliably operated along with other equipments in all likely situations. For instance Real Time Thermal Rating (RTTR), low sag conductors reached this level of maturity.

• Some are in development phase, i.e. no feasibility questions remain, but some resources are needed to engineer some still missing brick (e.g. some operating IT, some kind of Flexible AC Transmission System – FACTS).

of 148



• Some are in research phase, i.e. some key-issue is not yet solved and hence feasibility is not demonstrated. Typically, distributed storage solutions are today no alternative solution to transmission grid development as their capability, regarding power as energy issues, is about 100 or 1000 times too small compared to transmission grid requirements. Implementation of superconductors and nanotechnologies is also still researched with no practical application yet.

This section presents an overview of selected new transmission technologies that have the potential for large scale integration in the transmission grid in Europe in the future.

16.2.1 TRANSMISSION LINES (OVERHEAD LINES AND CABLES) High Temperature Conductors (HTCs) are able to withstand higher operating temperatures, thus carrying higher amount of power compared to conventional conductors. However, as the losses depend on the square of transmitted current, operating at higher rates generates significantly more losses.

HTCs can enhance transmission capacity without impacting the negotiated right-of-way, ideally without modifications of transmission towers, but this is not always the case. Although existing lines are used, in some countries such projects have to go through the impact assessment procedure again, especially when expected currents are higher due to the increase of magnetic field level.

HTCs encompass a broad family of very different technologies in terms of potential for transmission capacity and investment costs level. This explains the diverging viewpoints observed between equipment manufacturers and TSOs: the appropriate selection of a conductor will follow an in-depth analysis of the power system including operational and climatic conditions, fatigue and safety issues as well as the overall investment costs. Gains in capacity can reach 30% for the most used HT Conductors, while transfer capacity could be more than doubled with some technical solutions such as composite type conductors.

HTC costs are generally higher (in some cases much higher) than conventional ACSR (Aluminium Conductor, Steel Reinforced) conductors. Investment cost figures need to be tuned by considering electrical losses, potential structure reinforcement, installation and maintenance costs. The assessment of performances over the whole life-time through a better understanding of reconductored lines (models, endurance testing and level of electrical losses) is essential to further extend HTC uses.

Among the studied technologies, High Temperature Superconducting (HTS) cables are the ones which are the farthest away from commercial applications. Some optimistic experts consider first applications of HTS by 2020 thanks to a second generation of materials (Yttrium Barium Copper Oxide, YBCO) and advanced deposition techniques, starting at distribution system level. However, the majority of manufacturers are much more prudent with regards to their use in transmission systems and do not consider any significant application at least before 2030. Costs and size of the cryogenic refrigeration units will

of 148



remain a major obstacle. Field tests experimentations within very specific situations (short distance, dense urban area, DC applications) will contribute to the further development of the HTS technology blocks.

Illustration: illustrating the above mentioned difficulties, the choice of HTC has been made for only two projects of the TYNDP: the 260 km long 400 kV overhead line between France and Italy, and the ongoing upgrade of a 220 kV line in Poland.

The High Voltage Direct Current (HVDC) technology has proven its reliability and attractiveness for long distance power transmission, long submarine cable links and interconnection of asynchronous systems. Converters to convert current from AC to DC and DC to AC are critical.

The most recent technology, self-commutated Voltage Source Converter (VSC), is more flexible than the more conventional line-commutated Current Source Converter (CSC) since it allows controlling active and reactive power independently.

HVDC key benefits are in terms of increased transmission capacity compared to conventional HVAC for the same asset size, and power flow controllability, which in turn can enhance the stability of the link and of its surrounding environment.

Although the investment costs of a VSC-HVDC converter station are higher than those of an AC substation, the overall investment costs of a DC transmission link can be lower than those ones of a corresponding AC interconnection if a certain transmission distance is reached (i.e. “break-even” distance). This break-even distance strongly depends on the specific project parameters: it is typically between 80 and 120 km for offshore submarine cable connections; while for onshore applications, the break-even distance between an AC and DC OHL is usually in the order of 700 km. Nevertheless, other constraints have then to be taken into account.

Typical applications of VSC-HVDC include the active control of flows, interconnection of offshore wind farms, black start functionalities and multi-terminal DC applications. This technology is a key component of future European grid architectures, as we already can observe in the TYNDP.

Meshed DC systems could appear with the advent of commercial DC breakers.

Illustration: around 45 HVDC projects representing some 10 000 km of lines (up to 800 km for the UK –NO interconnector), mostly undersea and located in north, west, central and south Europe, are described in the TYNDP 2012. Nevertheless, some cables are to be installed onshore, e.g. in France between Haute Normandie and the south of Paris.

Real-Time Thermal Rating (RTTR) – monitored cables/overhead lines, or Dynamic Line Rating –, are on their way to become a mature technology based on the real time control of

of 148



thermal rating of an overhead line or a cable. It aims at maximizing the capability of a transmission line/cable while respecting design margins, thus reducing potential congestion problems. Its further development will be facilitated by solving some practical integration challenges: integration with other tools, interoperability with protection equipment settings, coordination of RTTR monitored links, communication with SCADA and use of RTTR output values at a dispatch level.

Combined uses of RTTR measurements with weather forecast might significantly increase the value of RTTR for network operations: it could become an interesting option for TSOs to achieve higher transmission capacity ratings safely and reliably for existing systems, at relatively low investment costs (when compared to the investment needed for new transmission links). The challenge here consists in developing more reliable and precise wind forecasts.

Illustration: Real-Time Thermal Rating Projects do not explicitly appear as such in the TYNDP list, for they are not considered by TSOs as necessarily directly related to the development of the European transmission grid.

Underground and submarine XLPE (Cross-Linked Poly-Ethene) cables present a good potential for transmission. Such cables for HVDC applications are more and more used. For HVAC XLPE cables, however, notwithstanding the recent technological progress, the further deployment and consequent cost reduction, the cost barrier (when compared to conventional solutions) is still high and expected to remain so due to the intrinsic higher complexity and installation constraints of this technology.

Yet, the cost barrier might be reduced when all types of benefits stemming from this technology are considered, such as the consideration of losses during the whole life-time, authorization procedures duration in some countries, visual impacts, etc.

Nevertheless, these underground assets represent a specific risk for operation that has to be carefully analysed: on the one hand this technology is less exposed to external events, but on the other hand causes long outages when damaged.

Illustration: some above mentioned HVDC projects consider the use or will use XLPE cables.

Gas Insulated Line (GIL) is a proven, yet not widespread, technology mostly used in short length installations (exploiting tunnels, bridges, or other existing infrastructures). It allows carrying a much higher amount of power through a single line than conventional solutions and XLPE cables. Yet, it faces strong environmental concerns in terms of SF6 emissions, which are more than 20 000 times more harmful than CO2 emissions, with a cost ratio over conventional solutions that remains high. GIL deployment is likely to continue within niche applications valorizing existing nonelectrical infrastructures: much will also depend on the successful implementation of GILs in planned projects at European level (like it is discussed for the Brenner tunnel).

Illustration: pilot project in the Brenner Tunnel between Italy and Austria being currently under consideration, constituted of a 65 km long double circuit 400 kV Gas Insulated Line.

16.2.2 SUBSTATIONS Phase Shifting Transformers (PSTs) are a mature technology, implemented by TSOs in Europe to control active power through preventive or curative strategies. PSTs do not increase the capacity of the line themselves; but in case some lines are overloaded while capacity is still available on others parallel to them, then optimizing the transits with PSTs can increase the overall grid capacity. In the future, the focus will be on enabling issues: the development of shared PST models by TSOs and standards should facilitate PST integration in transmission systems. In parallel, the development of cross-border power trade and the integration of renewable generation will increase the need for such a technology, possibly operated by power electronics and enhanced by coordinated control protocols implemented within inter-TSO coordination centers.

Illustration: a dozen of Phase Shifting Transformers are to be installed in Europe in the coming ten years, like in Zandvliet (4th PST on the Belgian north border).

Fault Current Limiters (FCLs) comprise technologies with different degrees of maturity. When addressing novel concepts (High Temperature Superconducting FCL, solid-state FCL, hybrid FCL), technology challenges still remain to be faced before a commercial exploitation (especially for High Temperature Superconducting FCL). The implementation of joint testing facilities by TSOs at EU level would help converging on design types and materials, cost reduction and standards and might speed-up the technology take-up in some niche applications in Europe.

Illustration: such a technology is considered as a possible help in operations, but does not appear as full part of the TYNDP list of investments.

Flexible Alternating Current Transmission System (FACTS) equipment is a family of power electronics-based devices able to enhance AC system controllability and stability and to increase power transfer capability. FACTS are naturally compared by TSOs with mechanical driven equipment providing controllability features, such as Phase Shifting Transformers (a simpler, more robust, reliable and generally less costly solution, but with limited dynamic capabilities).

FACTS devices can be classified according to their shunt, series or combined types of connection. Shunt type devices present relevant features for reactive power compensation and voltage control, while series devices offer key advantages for active power flow control and transient stability enhancement.

of 148



Costs, complexity and reliability issues represent nowadays the main barriers to the integration of these promising technologies from the TSOs’ perspective. Up to present, shunt devices (like the SVC, Static VAR Compensator) have been the most widespread and mature FACTS technologies. Further FACTS penetration will depend on the technology providers’ ability to overcome these barriers, thanks to more standardization, interoperability and economies of scale.

Key technology challenges are in terms of power electronic topologies and exploration of new types of semiconductors replacing silicon. More user-friendly interfaces and proof of performance through field testing will contribute to improve TSOs’ confidence in these new technologies. Like other active equipments (HVDC (VSC) and PST), FACTS will be crucial for the future integration of RES into the European system, while delivering full benefits when subject to a coordinated control, in combination with Wide Area Measurement Systems (WAMS).

Illustration: such a technology is considered as a possible help in operations, but does not appear specifically under this name in the TYNDP list of investments. Nevertheless, some TYNDP projects involving banks of capacitors include SVC.

16.2.3 OPERATING STRATEGIES Wide Area Monitoring System (WAMS) is an information platform with monitoring purposes. Based on Phasor Measurements Units (PMUs), WAMS allow monitoring transmission system conditions over large areas in view of detecting and further counteracting grid instabilities. This early warning system contributes to increase system reliability by avoiding the spreading of large area disturbances, and optimizing the use of assets. Yet, some critical R&D challenges lie in signal accuracy and reliability, communication architectures and data processing.

Standards for data processing, large scale demonstrations, possibly in combination with other active equipment, will be needed to estimate benefits brought by WAMS.

Illustration: such a technology is considered as a possible help in operations, but does not appear as full part of the TYNDP list of investments.

Electric Storage: although not generally operated by TSOs, electricity storage solutions could have a significant impact on transmission planning and operations. Storage solutions (centralized ones like hydro pumping e.g. or decentralized ones like batteries in cars, if and when electric cars will be deployed massively) can provide TSOs with new options to cope with variable power flows.

Storage could help maximizing electricity system stability in case of any sudden drop/surge due to the variability of most RES generation plants. It could also support CO2 emissions

of 148



abatement targets either during off-peak periods, by avoiding electricity spillage, or during peak periods in the case of a generation mix that is highly fossil fuel dependent.

Historically, storage is related to technologies like Pumped Hydro and Compressed Air Energy Storage, whereas other storage technologies are not clearly addressing large scale system issues. Yet, there are still technical and mostly regulatory issues to be faced. In terms of regulatory issues, open questions are related to which players (private market operators contributing to system optimization or regulated operators) shall own and manage storage facilities. Implementing large scale demonstrations of storage solutions at European level appears to be a necessary step to validate both storage benefits based on full scale studies and the potential asset ownership options for storage regulations.

Illustration: as for now, there are around 15 projects among Europe, which are limited to the connection of hydro pump power plants, mainly in Switzerland, Austria, Romania, Spain and Portugal. As for storage demonstration projects, the TWENTIES project involving several ENTSO-E members, responding to the ENERGY 2009.7.1.1 call (optimization of the electricity grid with large-scale renewables and storage) can be quoted, as well as the Almacena project in Spain.

16.3 CONCLUSION As already mentioned, European TSO’s are supporting the development of the above mentioned new technologies by testing new products supplied by manufacturers, testing new technologies, influencing thus the improvement of the most relevant technologies. In fact TSOs are frontrunners in all these advances in new technologies, while carefully choosing the most promising ones.

Some of the technologies are still in a premature state and a large scale integration of these technologies in the transmission grid is not possible due to reliability constraints. As the TSO’s have the responsibility for the whole electrical system in their control zone, precaution is needed with respect to the introduction of new technologies.

As a matter of fact, none of the examined technology is a universal solution. Each project has to be considered in a dedicated study assessing the best fitting technologies.

For that reason, some technologies play a real role in the European TSOs’ transmission projects in the next ten years, and some other technologies do not appear yet, for their level of maturity and reliability are not satisfying yet within this timeframe.

Moreover, as some projects are considered as demonstrations rather than network development projects, they do not appear at the TYNDP level. The ENTSO-E R&D Plan is providing a larger and exhaustive approach of projects involving new technologies, and for that reason, the reader is invited to refer to this document in order to get more detailed information regarding new technologies.

17 APPENDIX 6: IMPORT CAPACITY COMPARED TO NET

GENERATING CAPACITY The European Council52 has proposed a very simple criterion for interconnection development, asking from every Member States a minimum import capacity level equivalent to 10% of its installed production. The result is depicted below.

10% to 15%

FIGURE 45: IMPORT CAPACITY/NET GENERATION CAPACITY IN 2011

The above map shows that Island systems or electricity quasi-Island systems (Ireland and UK, Iberian peninsula) but also Poland show the lowest import -generation ratios. France and Italy are slightly under the 10% threshold and Germany, Romania, Bulgaria and Greece slightly above. All other countries display index levels greater than 15%. This shows both the power and the limits of the indicator: every Baltic state for instance display a high index level. As they are mutually interconnected, assessing the indicator for all three of them, and towards EU countries, would lead to a mere 4%. 52 ,��6�!��5��<�"��5��!�5��<�� )��

The criterion computed for the present situation can be reassessed after a projection in 2020, assuming all projects of pan-E significance implemented. The result is depicted below:
