2 2 Basic facts Area: km 2 Population: Number of electricity consumers: Number of TSOs: 1 Number of DSOs: 3 Peak load: 2.2 GW Average interruption of electricity: N/A Bosnia and Herzegovina Power System 2

3 Global map of the grid and of its interconnections 3 Interconnectors with: Croatia Serbia Montenegro Bosnia and Herzegovina Power System 3

4 4 Grid facts and characteristics 400 / 220 / 110 kv voltages 6.341,48 km of HV lines 864,73 km 400 kv 1.524,80 km 220 kv 3.951,95 km 110 kv (OHL 3.920,60 km and cable 31,35 km) 145 substations 9 substations 400/x kv 8 substations 220/x kv 128 substations 110/x kv Bosnia and Herzegovina Power System 4

5 Structure of electrical power system 5 Transco (Transmission system owner) and ISOB&H (System operator) are working closely in order to ensure power supply in the whole country. SERC (State Energy Regulator Comission) oversees Transco and ISOB&H operations. 3 Power utilities transfer it s energy to Transco s grid. Bosnia and Herzegovina Power System 5

7 7 Information on TSO(s) Name: Independent System Operator in Bosnia and Herzegovina (ISO) & TransCO (TSO) - Elektroprenos Elektroprijenos B&H Network length (km): 6.341,48 km Served area (km²): km 2 Annual transmitted energy (TWh): 17,68 website: & Bosnia and Herzegovina Power System 7

8 8 Cooperation of TSO and DSOs There are three DSO s, which are in the same time power utility companies (Generation and Distribution and Supply). Current activities are related to the legal and functional unbundling of DSO s and supply companies. On a daily basis they inform ISOB&H of planned activities. Bosnia and Herzegovina Power System 8

9 9 Responsibilities of TSO & DSOs This topic is very complex due to complex state structure (different entities have different laws, etc...) in the country. TSO operates levels are 400, 220 and 110 kv, DSO operates at lover voltage levels (35, 20, 10 kv) Bosnia and Herzegovina Power System 9

10 10 Power structure of the country Thermal power plants 49,4% Hydro power plants 32,4% From other systems 18,2% (Generation structure - for 2014) Bosnia and Herzegovina Power System 10

11 11 Installed capacity with reference to primary resources Installed capacities (GW), year 2016 Coal (lignite and brown coal): 1.8 GW Hydro power: 2 GW Distributed power generation (hydro and solar): 0.1 GW Bosnia and Herzegovina Power System 11

12 Energy production with reference to primary ressources 12 Electricity generated (TWh), year Coal (lignite and brown coal): cca 60 % Hydro power: cca 38 % Distributed power generation (hydro and solar): cca 2 % Bosnia and Herzegovina Power System 12

13 Development of generation capacity since. 13 Renewables (excluding hydro) Hydro Coal Lignite Gas Nuclear? Bosnia and Herzegovina Power System 13

14 14 Comsuption per customer groups Industry 36,3% Traffic 0,8% Households 43,5% Other comsuption 19,4% (source: Agency for Statistics) Bosnia and Herzegovina Power System 14

15 Location of renewable energy sources 15 HPP are blue TPP are orange Bosnia and Herzegovina Power System 15

16 16 Development of wind power Currently there are no installed WPP. By the end of 2016, there should be several units in southern parts of the country. Bosnia and Herzegovina Power System 16

17 Development of photovoltaic power 17 Currently, there are small PV plants all over the country. Most of it is installed in the southern parts of B&H. The total ammount is kw Bosnia and Herzegovina Power System 17

18 RES installed capacity and production since After the war in Bosnia and Herzegovina, two large hydro power plants were built. The total installed capacity is cca 100 MW. Besides that, small amounts have been installed on distribution level. Wind power plants are not yet installed, several WPP are expected to be commissioned in Bosnia and Herzegovina Power System 18

19 Price development for industry consumers 19 0,12 KM/kWh = 6,13 cent/kwh (without taxes) Bosnia and Herzegovina Power System 19

20 Price development for households (KMpf)/kWh = 8,18 cent/kwh (with taxes) Bosnia and Herzegovina Power System 20

21 Electricity market organisation 21 very complex electricity market because of complex state structure. Day ahead planning Bosnia and Herzegovina Power System 21

22 22 Power balance in 2014 Generation (TWh): 14.4 Consuption (TWh): 11.9 Imports (TWh): 3.1 Exports (TWh): 5.9 Losses (TWh): 0.3 Bosnia and Herzegovina Power System 22

23 23 Energy exchanges in 2014 Croatia: import 1,96 TWh, export 2,2 TWh; Serbia: import 0,99 TWh, export 0,61 TWh; Montenegro: import 0,21 TWh, export 3,23 TWh; through distribution network: import 0,05 TWh. Bosnia and Herzegovina Power System 23
