The project, financed by German development bank KfW, bears great importance for the power transmission system in Western Serbia, as well as the power transmission systems in southeastern Europe and Italy. The project involves replacement of the existing 220 kV overhead line between Bajina Basta and Obrenovac Transformer Substations, as the ones can no longer meet the demand for an increased transmission capacity. Additional reasons lie in the growing operating and maintenance costs that make the replacement much needed.
New 400 kV OHL is to be installed, enabling a future interconnection between South East Europe and Italy to be established. The Transformer Substations are to be reconstructed accordingly.
Having in mind the topography of the mountainous region of Western Serbia, the project was particularly challenging with respect to site survey and selection of the most suitable 400 kV OHL route.
