Serbia’s electricity transmission network needs upgrading and expanding. One section, the existing overhead lines, and substation equipment at Bajina Bašta, and the Over Head Lines (OHL) to Valjevo, Obrenovac and Belgrade 3, are in extremely poor condition after 50 years of continuous service. There is also a need to develop a new 400 kV corridor to accommodate potential projects and to allow for the future development of the electrical transmission system, not only in Serbia and the Western Balkan region but also connecting to North-East and South-East Europe. WBIF is assisting the project’s promoter, EMS, with the potential upgrade of the existing 220 kV network in Western Serbia to 400 kV.
The technical assistance started by preparing a pre-feasibility study to identify options and potential network topologies for the upgrade. This resulted in a plan to upgrade the 220 kV circuits to 400kV between Obrenovac and Bajina Bašta, with a potential loop into Valjevo. In the project’s second stage, a full feasibility study was undertaken for this scenario, including site investigations, corridor definition, financial and economic assessments, and a comprehensive environmental and social impact assessment. A 400 kV upgrade scheme proved to be the most cost-efficient option compared to all 220 kV development options.
The proposed project will benefit the existing customers of EMS by improving the reliability and efficiency of the system. It will also have an important role in improving the regional exchange of electricity in the Western Balkans, which will significantly increase with the commissioning of a 1000 MW undersea cable, between Italy and Montenegro and onto Serbia, presently under construction.
The major benefit of the proposed double circuit 400 kV transmission line is an increase in the network capacity to facilitate the growth load, new generation connections and regional exchanges of electricity in the Western Balkans. It will further develop the regional energy market and the system’s operations such as flexibility and stability. There will be improvements in the reliability of the regional network and the overall security of supply. The development will eliminate constraints in the region related to electrical energy transmissions and exchange. These benefits could include network capacity increases for important interconnections with Bosnia and Herzegovina, Montenegro, Italy in the south, and Romania and Ukraine in the north.
The project promoter is EMS - the national company responsible for the Serbian transmission network. This company has proven sound in financial and operational terms, given the main conclusion from the Financial and Economic Assessment was that EMS has sufficient financial strength to obtain the required loan and to repay all contractual payments on time.
