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. 330 KV TRANS MIS S ION GRID DEVELOMPMENT 10 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.

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.

INTERCONNECTION LITHUANIA – S WEDEN 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; S ECURITY OF S UPPLY 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. S ECURITY OF S UPPLY AND POWER BALANCE, INITIAL DATA ABOUT THE S ITUATION 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? CONCLUS IONS • The Baltic power systems are isolated from the EU market 21 (island); • 142.8 mln. € are marked in the Ignalina NPP closure programme for the Lithuania – Poland interconnection; • After closure of the Ignalina NPP (year 2009): Lost of ~60% of the cheapest electricity generation; Increased electricity tariffs; Lost electricity export; Lost fuel diversification; Electricity production based on Russian natural gas supply.
