Work has recently commenced on the upgrade of the Bajna Basta substation in Serbia, with the voltage set to be increased from 220 kilovolts (kV) to 400 kilovolts (kV). The substation forms part of the third section of the Trans-Balkan Corridor, which is one of the most important electricity projects in Serbia and the wider region.

The corridor project involves the construction of a new 400 kV double-circuit transmission line linking Obrenovac and Bajna Basta (construction of which began in June last year), as well as the addition of two transmission bays at the Obrenovac substation. The total value of the third phase of the project is 113.5 million euros.

At the Bajna Basta substation, a new 400 kV switchyard will be constructed and two 400/220 kV power transformers, each with a rated capacity of 400 MVA, will be installed. These works will enhance the capacity and reliability of the transmission network in western Serbia, creating the necessary conditions for the future grid connection of the Bistrica pumped-storage power station.

This corridor is one of the largest investment projects undertaken by EMS, Serbia’s state-owned electricity transmission system operator. To date, the first two sections have been completed: the 400 kV transmission line from Pančevo 2 to the Romanian border and the 400 kV transmission line from Kragujevac 2 to Kralevo 3, which included the upgrade of the Kralevo 3 substation to 400 kV.

The third section is scheduled for completion in 2028, whilst the fourth section, connecting Bajna Basta in Bosnia and Herzegovina with Visegrád and Prevlja in Montenegro, is scheduled for completion in 2029.
