The foundation stone was laid today in Serbia for the third section of the Trans-Balkan Electricity Corridor. The investment amounts to EUR 100 million. It entails a high-voltage overhead power line of 109 kilometers between Obrenovac and Bajina Bašta, equipping two new switchyards in the Obrenovac transformer substation and upgrading the Bajina Bašta substation to 400 kV. The fourth and last section, with the interconnections with Bosnia and Herzegovina and Montenegro, is planned to be completed in 2028.

Serbian Minister of Mining and Energy Dubravka Đedović Handanović said at the groundbreaking ceremony for the third section of the Trans-Balkan Corridor that it is the most important project for the transmission system not only in the country but in Southeastern Europe.

“What highways are for transportation, high-voltage power lines are for energy, and today we are beginning the works on the new part of the most important energy highway,” she said in Obrenovac and added that the segment would enhance the security of supply for consumers in western Serbia.

The third section of the Trans-Balkan Electricity Corridor involves the construction of an overhead power line of 109 kilometers on 309 towers, equipping two new switchyards in the Obrenovac substation and lifting the voltage level in the Bajina Bašta substation to 400 kV.

The project is financed with a EUR 64.5 million loan from Germany’s KfW Development Bank, a grant from the European Union via its Western Balkans Investment Framework (WBIF) of approximately EUR 21 million, and own funds of the Serbian transmission system operator Elektromreža Srbije (EMS), according to the state-owned company’s announcement. The third section is worth EUR 100 million, of which EUR 71 million is for the overhead power line.

“With the completion of the entire project, we will additionally strengthen the links with Bosnia and Herzegovina and Montenegro and beyond, with Italy,” Đedović Handanović stated.

She recalled that significant transmission grid investments are planned in the next five years, including the construction of the Pannonian Corridor toward neighboring Hungary. The priority projects in the segment are worth EUR 500 million in total, the minister revealed.

“I expect the contractors not to be late with the works, so that the project is completed within two and a half years, as it is planned,” Đedović Handanović stressed.

Matejić: Final section to be finished in 2028

General Manager of EMS Jelena Matejić said the construction of the entire Trans-Balkan Corridor is worth more than EUR 200 million. She noted that it includes 323 kilometers of 400 kV power lines, voltage level upgrades for two transformer stations and switchyards in three of them.

The investments in the Trans-Balkan Corridor are estimated at more than EUR 200 million altogether

“Except this section, the third one, we will also have the fourth, for which the funds have been secured, and it will be finished in 2028,” Matejević asserted.

The old lines in western Serbia of 220 kV will be replaced with new, 400 kV systems, which will create possibilities for connecting the planned Bistrica pumped storage hydropower plant to the grid, according to EMS. The contractor is Kodar Energomontaža, and the works are expected to be completed by 2027.

EU donated EUR 38.3 million for Trans-Balkan Electricity Corridor

Head of the EU Delegation in Serbia Emanuele Giaufret pointed out that the funds the EU has earmarked for the current section are part of wider support.

“The EU has secured a EUR 38.3 million donation for the whole Trans-Balkan Corridor, together with KfW’s favorable loans. Over the years, the EU has earmarked more than EUR 1 billion for the energy sector in Serbia. This project is important for the rest of Europe as well, because it will contribute to the creation of a wider, integrated system, which will enable a more stable supply to consumers on the entire continent, as well as to avoid problems in the future,” he stated, as quoted by EMS.

The first section of the Trans-Balkan Corridor, from the city of Pančevo near Belgrade to the Romanian border, was finished in 2017. The second one, between Kragujevac and Kraljevo in central Serbia, is operational since 2022. It included substation upgrades in the two cities. The fourth section needs to connect Bajina Bašta with nearby Višegrad in Bosnia and Herzegovina, and with Pljevlja in Montenegro.
