Serbia’s electricity transmission operator EMS has signed a contract with a consortium of construction firms to build the new 400/110 kV Belgrade 50 substation in Ugrinovci. The project, worth around 50 million euros, is scheduled for completion in 2027.
The substation will feature complete 400 kV and 110 kV switchyard systems, a 400/110 kV transformer block equipped with two 300-MVA transformers, auxiliary power facilities, relay and control buildings, as well as a fully prepared site with internal access roads and operational infrastructure. EMS confirmed that procurement and delivery procedures are already underway for key components including transformers, protection and control equipment, metering systems, telecommunications infrastructure and high-voltage hardware.
As a core element of the BeoGrid 2025 initiative, the Belgrade 50 substation will operate alongside a planned dual-system 400 kV transmission line toward South Banat. This reinforcement is considered one of the pillars of Serbia’s long-term transmission network expansion. In parallel with the substation project, EMS launched construction in September of two single-circuit 400 kV lines that will form the future connection point for transmission line 450. The entire BeoGrid program—including substations and overhead lines—represents a total investment of 204 million euros.
The development is part of the wider Northern Corridor for Electricity Transmission, intended to establish a new high-voltage route capable of transferring large quantities of electricity from South Banat, a region rapidly emerging as a major center for renewable-energy projects. Integrating this growing renewable capacity requires timely expansion of the transmission system, which BeoGrid 2025 is designed to achieve.
Beyond its strategic importance for integrating renewables, the project is expected to enhance supply reliability for consumers in Srem and the greater Belgrade area, where urban expansion and major national infrastructure projects are driving up electricity demand.
