Jelena Matejić, General Director of Elektromreža Srbije (EMS), today visited the reconstruction site of the Đerdap 1 hydroelectric power plant, a crucial hub for Serbia’s electricity system and the wider European region.
“The Đerdap 1 hydroelectric power plant is integral to our transmission system. It delivers approximately 5,000 gigawatt-hours of energy annually and plays a key role in providing secondary regulation for the Serbian Electricity System (EES), ensuring the system’s reliable operation. Its smooth functioning is vital for the stability of Serbia’s entire power system. Additionally, Đerdap 1 connects central Serbia with eastern Serbia and Romania via the 400 kV transmission line between Đerdap 1 and Portile de Fier,” Matejić explained during the tour.
The reconstruction of this strategic facility is expected to be completed by 2025. The total cost of the project’s two phases is approximately 1.13 billion dinars, with around 682 million dinars (60 percent) already spent.
“The transmission line corridor from Đerdap 1 to TS Bor 2 and TS Niš 2 is one of the busiest routes in Serbia’s transmission network. It also forms part of the 400 kV ring connecting Serbia, Bulgaria, and Romania. This highlights the importance of the reconstruction and the investments made by EMS to ensure energy stability for both our country and the region. Our experts have meticulously planned the project, and their commitment is of national significance,” Matejić said.
The reconstruction of Đerdap 1 is divided into two phases. Phase 1, which has been completed, involved replacing high-voltage equipment. The more extensive Phase 2 includes the complete overhaul of the 400 kV substation, including the construction of a new command building with all supporting systems, the construction of four new relay houses, and the reconstruction of four existing ones. This phase also involves new cable ducting, replacement of the remaining high-voltage equipment from Phase 1, updating busbars, and complete replacement of connecting equipment and insulator chains.
