2 2 CONTENTS INTRODUCTION SEE TRANSMISSION SYSTEM RECENT TRANSMISSION PROJECTS FUTURE BOTTLENECKS FUTURE TRANSMISSION PROJECTS

3 3 INTRODUCTION 9 countries, different characteristics annual consumption 4 TWh – 56 TWh peak loads 0,7 GW – 9 GW SEE: ~30 GW, 230 TWh electricity importing region exporters: Bulgaria, Romania and Bosnia and Herzegovina power plants: hydrology dependence, old facilities, high production prices price of electricity: regulated

4 4 SEE TRANSMISSION SYSTEM 400 kV, 220 kV, 110 kV; generally well-meshed high interconnection capacities high network availability

7 RECENT TRANSMISSION PROJECTS Reconnection of the 2 nd UCTE Synchronous Zone to the main UCTE grid  October

8 8 RECENT TRANSMISSION PROJECTS (2000 – up to now)

9 9 SEE TRANSMISSION SYSTEM Interconnection capacities (sum) – SEE + (A, HU, GR, SLO)

10 10 SEE TRANSMISSION SYSTEM Interconnection capacities (sum) - EUROPE

11 11 SEE TRANSMISSION SYSTEM NTC values – winter 2010/2011 (ENTSO-E)

12 12 SEE TRANSMISSION SYSTEM Peak loads and transmission capacities based on the NTC values

13 13 POSSIBLE FUTURE BOTTLENECKS Interconnection lines – not congested Internal lines – somewhere congested

14 14 FUTURE TRANSMISSION PROJECTS MAIN DRIVERS:  conventional power plants connection  renewables (wind)  market oriented investments INTERCONNECTION LINES:  several projects under consideration (feasibility studies, ideas)  generally large interconnection capacities in SEE region INTERNAL TRANSMISSION SYSTEMS:  reinforcements  maintenance  revitalization ANCILLARY SERVICES  regional market (benefits: wind integration, cost reflective services) OBSTACLES:  costs, transmission fees  environmental  politics KEY ISSUES:  economically justified investments  TSO’s → realistic and well prepared investment and development plans  regulatory authorities (more dynamic role)

15 15 POSSIBLE REINFORCEMENTS (plans, ideas,…)
