3 CIGRE National Committee KOSOVO The CIGRE National Committee of Kosovo was recognized by the Administrative Council of CIGRE, consulted by correspondence on September 8 th 2017, after considering the request for formal recognition dated August 2 nd 2017, as a National Committee of CIGRE International.

4 An overview of Kosovo s transmission system development

5 KOSTT s Role in the Power System of Kosovo KOSTT J.S.C is the electricity Transmission, System and Market Operator of the Republic of Kosovo, a publicly owned company with 100% of shares owned by the Republic of Kosovo. KOSTT manages the operation, maintenance and development of the electricity transmission system at 400kV, 220kV and 110kV. Transformers connected to the distribution network: 220/35//10 kv and 110/35/10 (20) kv also belong to the transmission system. KOSTT complies with the provisions of the: Grid Codes Electrical Standards Code & Technical Equipment Code Connection Charging Methodology ENTSO-E Operational handbook As a result of the central geographical position, KOSTT, although small in size, represents a very important transmission hub in Southeast Europe

6 Role and Responsibilities KOSTT performs: Real Time Operation Observability of neighboring transmission grids Short (Day Ahead), Medium and Long term Planning\Analysis Provides Transmission services under regulated tariff Provides non-discriminatory third party access to the grid Enhances reliability and balances the system Planning, development and maintenance of network Facilitation and operation of the market 6

7 Licenses for Transmission System Operator and Electricity Market Operator, KOSTT is responsible for: Planning, operation, maintenance and development Efficient, economic and coordinated operation of the transmission system, including cross-border flows Balancing of the system Provision of non-discriminatory access for transmission system users Encouraging efficient competition in electricity generation and supply Encouraging economic efficiency in applying Market Rules and performance of activities in compliance with the Market Rules Management of the final settlement processes

11 Investments in Transmission System Investments in Transmission System Investments ,924, Investments in Transmission System/Asset value Asset Value with KOSTT-KEK split-up Investments % 11% 50 projects mil euro 11

12 Main Transmission Investment Projects Reinforcement category: /110 kv substations, - Interconnection line 400kV Kosovo Albania together with LFC project - 12 new 110 kv lines and re-conductor (increase of capacities) - 5 autotransformers and 21 power transformers Load support category /35/10 kv Substations Refurbishment Category - 90% of existing Substations are renewed ( modern equipment's) System Support Category - New SCADA/EMS system/modern telecommunication infrastructure - New measurement systems at interconnection and with other connected parties - 100% new relay protection systems 12

13 Aims /achievements so far Enable security and quality of supply as far as transmission capacity concerned Reduction of power losses Reduction of energy not supplied Fully complaint with GRID CODE and ENTSO-E requirements Support for generation development/extensions in the connections Support for Renewable Energy Integration in Transmission System Support for market development and regional integrations of KOSTT Ensure stable transit flows through KOSTT network for regional power systems needs

14 400 kv Line Kosovo B (KS) Tirana 2 (AL) The line is finished in Jul 2016, 242 km, 2x490mm 2, 95 km Kosovo Territory, 36 M investment of KOSTT The line is still out of operation due to no implementation of Connection Agreement with ENSTO-E During past months the line was switched on, three times for short time only in the alert and emergency condition of neighbouring system i.e. OST, when they requested from KOSTT to prevent cascading effects of overloaded lines. Those activities prove the importance of the line for security of regional transmission network. The line is an important interconnector which supports increase of power transactions in region and security operation of regional transmission network.
