Electric power in Bosnia and Herzegovina has been produced and used for more than 115 years. The first power station was built in 1888 next to the coal mines in Zenica, seven years after the first power plant in the world was built and put into operation in New York in 1881. Due to poor economic development, the process of electrification in Bosnia and Herzegovina was slower than the electrification of developed European countries. By the end of 1919, only 1.1% of the settlements were electrified in Bosnia and Herzegovina. In 1945, 16% of the settlements had electricity, and in 1980, 93% of the populated areas were electrified. Electric power production in 1945 reached 65 million kWh. In 1992, production was 13.7 billion kWh, and in 2002, 10.8 billion kWh was produced.

Phase two: From 1948 to 1958, 35 and 110 kV transmission networks were used for the transmission of electric power. At that stage, the expansion and connection of the areas of regional electrification within the transmission network was intensified.

The electric power consumption in 1945 was 55 million kWh, in 1991, 10.6 billion kWh, and in 2002, 9.8 billion kWh. Along with the electrification of Bosnia and Herzegovina and the increasing use of electricity, the need to connect power stations and the centers of consumption of electric power by transmission network arose. The capacity and voltage level of facilities and plants for transmission and transformation of electric power were increased. Important 5 kV, 6 kV and 10 kV overhead lines for the transmission of electric power in Bosnia and Herzegovina were built in early 20-ies of the last century. The first 10 kV overhead lines were built between Sarajevo - Ilidža and PP Kreka - Tuzla.

Furthermore, the dynamic of the construction of the first lines of higher voltage levels in Bosnia and Herzegovina was as shown in the table below. Phase two: From 1948 to 1958, 35 and 110 kV transmission networks were used for the transmission of electric power. At that stage, the expansion and connection of the areas of regional electrification within the transmission network was intensified.

Power stations were connected and the usage of their capacities were synchronised. The technical conditions for the reliable supply of the centers of electric power consumption were created throughout Bosnia and Herzegovina, and the electric power system of Bosnia and Herzegovina was formed. Phase three: From 1958 to 1976, the transmission network in Bosnia and Herzegovina consisted of 110 and 220 kV facilities. Overhead lines and substations were built by the adopted unified technical concept and requirements of their operation in the power system of Bosnia and Herzegovina. The connection to the power lines of other electric power systems in the former Yugoslavia was in progress and the technical conditions for the reliable transmission, required import, transit and export of electric power were being created. Phase four: From 1976 to 2002, the transmission network in Bosnia and Herzegovina consisted of 110 kV, 220 kV and 400 kV facilities. These networks were built by the adopted unified technical concept and requirements of Bosnia and Herzegovina electric power system.
