11 11 BALTIC ENERGY STRATEGY Prepared Baltic energy strategy is published for public opinion; Main targets: – integration of power systems and gas systems into EU energy systems and markets; – diversification of primary energy sources and supplies; – increase the energy efficiency at the demand side and in the energy transformation sector; – develop the transit routes for energy products, including electricity; – strengthen education, research and development in the energy sector; – elaboration and implementation of common policy on energy imports from non-EU countries; – integration of the Baltic power systems into markets of Central Europe and Nordic countries; – to apply a request to UCTE President for conditions and terms of synchronous interconnection of the Baltic States power systems with UCTE; – renew the large power production capacities; – to use possibilities and benefits from development of distributed electricity generation; – increase the share of renewable energy sources in the electricity mix

12 12 LITHUANIAN ENERGY STRATEGY Lithuanian national energy strategy approved by Parliament (Seimas) in 2007-01-27; Integration of power system and gas system into EU systems and markets; Diversity of primary resources, increase use of local resources, to limit use of gas for electricity production up to 30% of yearly fuel balance; Ensure the continuity and development of safe nuclear energy; to put into the operation of a new regional nuclear power plant not later than by 2015; Renovate power plants, power and natural gas transmission and distribution systems as well as we district heating systems increasing their efficiency and reliability; Not later than by 2012, to connect Lithuania’s high voltage electricity networks with the networks of Scandinavian countries and Poland; Further develop regional cooperation; Construct a natural gas storage facility in Lithuania, develop a common regional natural gas storage facility, construct, a common liquefied gas import terminal in the Baltic region; Increase the share of renewable energy resources in the national balance of primary energy at least up to 20% by 2025;

14 14 THE CLOSURE OF THE IGNALINA NPP Unit I was shut down in December 2004 The closure of Unit II is scheduled in 2009 The Ignalina NPP can be substituted by the Lithuanian PP, but this power plant has to be upgraded to meet environment requirements

15 15 On 26th January 2006, during an energy conference in Vilnius, government officials from three Baltic countries agreed to commission a feasibility study for a new nuclear power plant in the region. On 27th February 2006, the Prime Ministers of Lithuania, Latvia and Estonia issued a communiqué expressing their approval of construction of a new nuclear plant in the region and inviting the national energy companies to invest in the Project. The memorandum of understanding about conducting the feasibility study on the building of a new nuclear plant was signed by the heads of Lietuvos Energija, Latvenergo and Eesti Energia on 8th March 2006.

39 39 IMPACT OF WIND PP TO ELECTRICITY PRICE

40 40 ETSO VIEW TO INTEGRATION OF WIND PP Necessary to speed-up construction of network infrastructure; Participation of wind PP in ensuring stability of power system, voltage control during short circuits and etc.; Ensuring balance and frequency control of the power system; Support of studies for integration of renewables into power system; Promote secure planning by limiting total capacity of renewables; Evaluate impact to international power flows.

41 41 PROBLEMS Big impact to power system balance control; Additional costs for power system control, balancing; Limitation of total installed capacity of wind PP; Difficulties with land ownership, rent, preparation of detail plan, environment impact assessment, unfriendly view of neighbours (not in my backyard); Impact to electricity price; Renewables reduce part of market, limits competition; Big pressure from companies which wants to construct wind power plants.

42 42 FUTURE DEVELOPMENT OF WIND PP Take into account policy of EU on development of renewables; In 2010 – 200 MW of installed capacity of wind PP; Most probable future development of wind power plants after 2010. How much? 50-100-200-400MW? Off-shore wind power plant 200-300 MW; Study for development of off-shore wind PP up to 1000 -1500 MW. Future development of wind PP limit not stable production from this type of production, network possibilities, necessity to have power transfer reserve in transmission grid, impact to power system balance; Development of other renewables (biomass PP, etc.).
