The project significance:
This project is a part of bigger initiative from the Connectivity Agenda – Trans-Balkan Corridor, which will connect Romania, Serbia, Bosnia and Herzegovina and Montenegro by 400 kV transmission line, whereas, through MONITA HVDC interconnection, these countries will be connected through electrical power with Italy. Section of constructing Trans-Balkan Electricity Corridor through Montenegro is one of the biggest electrical power endeavors in this country.
Elnos Group works:
Tasks assigned to our teams include replacement of high-voltage equipment, reconstruction of the relay system for protection and control, reconstruction of system for own consumption as well as integration of SCADA system in substations. According to preliminary figures, by the end of big reconstruction of substations throughout this country, our teams shall have laid 300 kilometers of cables, 200 new cabinets for protection and control and 150 high-voltage devices.
Substations 220/110/35 kV Podgorica 1, 400/110 kV Podgorica 2 and 400/220/110 kV Pljevlja 2 are the biggest electrical nodes in Montenegro. Work on these substations is the most comprehensive and most complex due to their strength and power, voltage level, number of important connections out of these substations and interconnective transmission lines connecting Montenegrin electrical power system with adjacent electrical power systems. Each substation is specific and special. Thermal power plant in Pljevlja distributes power to Pljevlja 2 substation directly. In Podgorica 2 substation, there is the most significant 110 kV transmission line node with 400/100 kV transformation, and substation Podgorica 1 is 220 kV and 110 kV node with 35 kV outputs powering the capital of the country. These three substations are the biggest in the country and have an important role in operation of Montenegrin electrical power system. Our teams started complex works on their reconstruction and entire endeavor, according to plan, should complete by October 2022.
