NEIGHBOURHOOD PROGRAMME LITHUANIA, POLAND AND KALININGRAD REGION OF RUSSIAN FEDERATION Perspectives of Offshore Wind Energy development in marine areas of Lithuania, Poland and Russia 2.4. Study on perspectives of main grid network interconnection between countries and with potential wind parks 2007-12-10 www.eksponente.lt 1 The problem • Lack of reliable knowledge concerning perspectives of off-shore wind power parks interconnection between countries and with potential wind parks are limiting forecasting and planning of investments into this kind of perspective renewable energy. 2007-12-10 www.eksponente.lt 2 Main tasks 1. 2. 3. To overview the state and problems of interconnection of Polish, Lithuanian and Kaliningrad district (Russia) electricity power grids. To analyse EU and national institutional frame work of power grids development. To define and analyse different scenarios of interconnection of potential off-shore wind parks. 2007-12-10 www.eksponente.lt 3 Preface • In May 2004 the EU integrated eight countries from Central and Eastern Europe, as well as Malta and Cyprus, into what is about to become a truly pan-European Union. • But whereas the political EU enlargement is proceeding smoothly, electricity enlargement turns out to be a more complex undertaking, which is far from being achieved at present. • Since the mid-1990’s, the accession countries had worked hard to bring their energy sectors in conformity with the EU acquis communautaire. 2007-12-10 www.eksponente.lt 4 The objective of EU electricity enlargement is to move towards a single, sustainable European electricity market: • A single market refers to the expectation of a competitive market and the efficient allocation of generation and transmission resources, at least at a regional level, if not at the level of the new EU 25 at large. • Sustainable refers to the ability of the electricity system to meet the environmental objectives of the EU, in particular with regard to the share of renewable in electricity production and the greenhouse gas targets, while assuring reliable electricity supply at reasonable costs. • Establishing open competitive markets while at the same time pursuing environmental objectives is not necessarily a contradiction. • A benchmarking approach of comparing different reform objectives can make cross-country comparisons possible. 2007-12-10 www.eksponente.lt 5 When considering the electricity map of the region, one clearly distinguishes three sub-regions: • The Central European Countries (CEC) are the former CENTRELcountries (Poland, Czech and Slovak Republics, Hungary) which are emerging as the core-zone in Eastern Europe; it’s considering Slovenia and Croatia also as being part of this region. These countries present by far the biggest market and assemble the strongest players of the region; • South Eastern Europe (SEE) consists of the EU candidates Romania and Bulgaria as well as the other Balkan states (except Albania); • The Baltic countries (Lithuania, Latvia, Estonia) are still part of the North-West Russian electricity system. The electricity sector in the Baltic countries is infinitesimally small, but it is politically highly sensitive (nuclear power in Ignalina/Lithuania, geopolitical issues with Russia, Kaliningrad, etc.). 2007-12-10 www.eksponente.lt 6 European power market • enlargement of European Union and integration into European and World economic structures requires significantly increase electricity market integration, which results in less than 10% of Europe’s electricity being traded across borders now 2007-12-10 www.eksponente.lt 7 Trans-European networks priority projects for electricity 2007-12-10 www.eksponente.lt 8 Priorities of EU Power Links Concerning Infrastructure the Priority Interconnection Plan sets out five priorities: – Identifying the most significant missing infrastructure up to 2013 and ensuring an-European political support to fill the gaps. – Appointing four European co-coordinators to pursue the four of the most important priority projects: • • • • the Power-Link between Germany, Poland and Lithuania; connections to offshore wind power in Northern Europe; electricity interconnections between France and Spain; and the Nabucco pipeline, bringing gas from the Caspian to central Europe. – Agreeing a maximum of 5 years within which planning and approval procedures must be completed for projects that are defined as being "of European interest" under Trans-European Energy Guidelines. – Examining the need to increase funding for the Energy TransEuropean networks, particularly to facilitate the integration of renewable electricity into the grid. – Establishing a new Community mechanism and structure for Transmission System Operators (TSOs), responsible for co-coordinated network planning. 2007-12-10 www.eksponente.lt 9 Baltic power grid on cross-road European Union: •Invited Baltic States to become EU Members •Forgot integrate power nets Reconnection strategies: • Status quo • “Go West” • Integration 2007-12-10 www.eksponente.lt 10 Bottlenecks 2005 % of time 180 h 17 % 552 2 %h NO2 13 % 12403 %h FI h 80% SE 5% 1252 2 %h 657 18h% NO1 716% h 50 3888 2 %h 3563 3 %h 45 440 % h DK1 0% 30 h 111% h 16 27.1.2006 DK2 Timo Toivonen 11 400 kV Transmission Capacity RUS - FIN Huutokoski Vihtavuori 750 kV 400 kV 330 kV Toivila Kangasala 2000 MW 1400 MW Koria Yllikkälä Kamenogorskaja Hikiä Forssa Hyvinkää Kymi Anttila Nurmijärvi Tammisto Espoo Inkoo Loviisa Vyborg Länsisalmi NWPP/ Severnaja HELSINKI Vostotsnaja ST.

Only at end of 2006 construction of Estlink enabled to connect Baltic power grids to Scandinavian power market. Polish and Lithuanian inland interconnection of power grids provided to implement till 2015 year. Lithuanian and Swedish submarine interconnection possibilities are under investigation now and could be realised till 2015 year. 2007-12-10 www.eksponente.lt 31 Conclusion 2 • European Energy technological plan the first from four of the most important priority projects named the PowerLink between Germany, Poland and Lithuania. • By 2020, technologies will have to make the 20% renewable target a reality by permitting a sharp increase in the share of lower cost renewables, including the rollout of off-shore wind. • Priorities of such a targeted initiative could include getting large scale offshore wind competitive within the short term and paving the way towards a competitive European offshore Supergrid. 2007-12-10 www.eksponente.lt 32 Conclusion 3 • Trans European Supergrid discovers abilities to become as revolutionary efficient looking from point of stability of power supply as able to reach capacity factor till 70% and significant reduce power reservation needs. • This technical decision could open and connect energy markets of member States. 2007-12-10 www.eksponente.lt 33 Conclusion 4 • Comparing different scenarios of wind power parks interconnection, the most acceptable for Poland, Russia (Kaliningrad) and Lithuania is Line connection variant as Eastern Baltic arm of trans European Supergid. • No interconnection and combined interconnection scenarios require too much legislative changes and indirect investments related to enforcement inland grids and capacity reservation. • It’s also important that construction of Supergrid could avoid construction of inland connection between Lithuania and Poland, same as submarine interconnection Lithuania – Sweden. 2007-12-10 www.eksponente.lt 34 Conclusion 5 Tools: • Policy – EU strategic and financial support • Organization – BOSEC establishing • Environment – scientific support 2007-12-10 www.eksponente.lt 35 Thank you for your attention! 2007-12-10 www.eksponente.lt 36
