ABSTRACT This paper discusses East and Central European Electricity Infrastructure, Interconnections and Electricity Exchanges following segregation of the republics of former USSR and independence of East European countries, and likely developments in future years. It focuses on the present and future state of the electric power sector, future expansion of European power systems, co-operation, new capacity, separation of power systems in former USSR countries, the direction of reforming the industry, interstate relations in the fuel and energy complex, and impact of privatisation on electricity supply. First, power sector problems in countries in transition are reviewed. Serious deficiencies in electricity supply affect economic reforms, and lack of investment together with poor operational performance plague the power industry, particularly in the republics of former USSR. Important issues of the CENTREL power companies: Czech, Hungarian, Polish and Slovak are discussed, for example, (a) improvement in quality of the power systems, (b) interconnection with the UCPTE system, (c) co-ordination of co-operation with other power systems, and (d) beneficial energy transactions. Development of technical solutions of future operation with eastern neighbours including back-to-back couplers are also discussed. The German Power System following unification requiring synchronous operation of the East-West power networks is commented on together with new interconnecting lines for synchronising the systems late in 1995. Discussed also are technical, economic, financial and legal aspects of exchanging about 4GW between Russia, Belarus, Poland and Germany using a multi-terminal HVDC transmission system and the idea of a Baltic Ring forming a meshed interconnection around the Baltic Sea. Problems of co-operation in former USSR are also reviewed. Highlighted is the fuel and energy complex, rate of new capacity commissioning, use of existing generating capacity, and separation of power systems in a number of republics from the Unified Grid Network. Dynamics of changes in basic indexes such as installed capacity, electric power generation and consumption in countries of the Commonwealth of Independent States’ (CIS), and in electric power an energy exchanger in CIS countries and between Eastern Europe are also discussed. The paper then examines the role of Russian Power Systems in the future Unified Electrical Power System of the Euro-Asian Continent. In the foreseen future, a chain of power systems stretching from Beijing to Madrid with total length exceeding 10,000km will be interconnected, comprising national grids of China, Siberia, Kazakhstan, Russia, Southwest republics of former USSR, East Europe and West Europe.
