PROBLEMS
9
• In maintenance regimes – low security of supply in
Klaipeda region, impossible to reserve Klaipeda region through 110 kV net.
• Long 330 kV transit – Jelgava-Broceni-Grobinia-
Klaipeda-Sovietsk. During maintenance one of those lines possible shut-down of some regions.
• Lack of 330 kV cross section lines. Eastern and western system parts connected with one 330 kV double-link line Kruonis HPSPP-Lietuvos PP.
• In the far future it is necessary to improve security of supply for Vilnius region – should be build third 330 kV substation near Vilnius, to connect Vilnius and Neris 330 kV substations. Will be less dependency from Byelorussia system.

BOTTLENECKS AND DIFFICULTIES
11
• After 5-10 years Baltic region could be deficit area; • Interconnections with other market areas must be build for Security of Supply of the Baltic area and for extension of small Baltic power market;
• Fuel supply mostly from Russia; • Could be limited import possibilities from Russia in some periods.

POWER BALANCES AND SOS. POSSIBLE
SOLUTIONS
13
• Without Poland – Lithuania interconnection:
– not to close Ignalina NPP reactor No. 2. – close Ignalina NPP reactor No. 2 and build No. 3.
• Shortage in sufficient generation capacities after closure of INPP.
– New NPP. Only for whole Baltic. – No for NPP? Closure of INPP and not build of new
NPP? Then in Lithuania will be no longer NPP (losing of specialists).
– New CHP. – Import.
• Interconnection of Baltic power systems with other power systems is necessary for increasing SoS and for market.
• The best and cheapest solution – postpone close of
Ignalina NPP reactor No. 2 till 2017.

PRESENT STATUS OF LITHUANIA –
POLAND INTERCONNECTION
17
• According to the Accession Treaty to the European Union
2003, protocol No 4 on Ignalina Nuclear Power Plant in Lithuania, Article 2, paragraphs 3 and 9, the enhancement of security of supply in Lithuania is supported by EU in the context of closure of Ignalina NPP;
• LT-PL interconnection project is listed in the European
Commission “Quick start” projects list and in the updated TEN Guidelines
• 142.8 mln. € for the Project (LT-PL interconnection) for
2007-2013 are marked in the programme of Ignalina NPP closure;
• The line route has been defined on the Lithuanian territory; • Lithuanian side is ready to start immediately the implementation of the Project by establishing a project implementation company;
• Polish side is willing to continue with analysis.
INTERCONNECTION LITHUANIA –
SWEDEN
18
• Completed Pre-feasibility Study; • Capacity ~700 MW; • Investments – about 400 million €; • Technical and economical analysis is in progress; • Feasibility study will provide detailed technical and economical analysis of the Interconnection;
• Benefits:
– Integration of Baltic power systems to Nordel electricity market;
– Higher Security of Supply for Baltic and Nordic power systems;
– Better use of power resources in Baltic and in
Nordel;
SECURITY OF SUPPLY IN THE BALTICS
19
• The Baltic Power systems are isolated from the EU market (island);
• The capacity of Estlink interconnection will be only 4% of installed capacity of the Baltic States.
• Low security of supply after the closure of the Ignalina
NPP;
• The Baltic power systems have gas supply through only one gas supply source;
• Projected new gas pipe line routes bypass the Baltic
States;
• Very high dependence on gas fuel supply.
SECURITY OF SUPPLY AND POWER BALANCE, INITIAL DATA ABOUT THE
SITUATION
20
• increasing number of wind power (in 2010 planed
200MW).
• demand increasing is in accordance with average – maximum plan.
• Real start with construction of new capacity in Panevezys
CHP (35MW).
• Interconnection of Lithuanian and Polish power systems is not started.
• It is coming time to close NPP. New one?
