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 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): 51.197 km 2 Annual transmitted energy (TWh): 17,68 website: http://www.nosbih.ba & http://www.elprenosbih.ba Bosnia and Herzegovina Power System 7
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 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

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
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 1.492 kw Bosnia and Herzegovina Power System 17
RES installed capacity and production since 1995 18 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 2016.
