The Trans-Balkan Electricity Corridor is nationally and regionally significant and one of the Flagship projects under the EU's Economic and Investment Plan for the Western Balkans. The Corridor will contribute to the establishment of a regional power network connecting the electricity transmission systems of Bosnia and Herzegovina, Montenegro, and Serbia with Croatia, Hungary, Romania and Italy through 400 kV overhead lines or submarine cables.
This investment concerns the construction of a new double 109-km OHL transmission line, the upgrade of the substations Obrenovac and Bajina Bašta to 400kV voltage level and the construction of an additional two 400 kV line bays with the appropriate equipment, necessary for the line connection to the 400/220 kV SS Obrenovac.
