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.

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.

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.

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.).

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

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.

Connectivity of power markets
• Baltic Sates are technically
strongly connected to Russian
power market
• Baltic States have strong cross
boarder interconnections
• Estonian network allows to
import all power needed
• Baltic States have no
connections to other EU
countries

European Strategic Energy Technology Plan
EC has two key objectives for energy technology:
– to lower the cost of clean energy and
– to put EU industry at the forefront of the
rapidly growing low carbon technology
sector.
• To meet these objectives, the Commission
intends to put forward a first European Strategic
Energy Technology Plan for endorsement by the
2008 Spring Council.

• By 2020, technologies will have to make
the 20% renewable target a reality by

Conclusion 1
•
•
•
•
After accession of East European countries in EU still
not formed efficient interconnection of power grids and
electricity trade market.
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.

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.

• Policy – EU strategic and financial support
• Organization – BOSEC establishing
