Elektromreža Srbije (EMS) announced that it has signed a contract for the construction of a new 400/110 kV substation, Belgrade 50, located in Ugrinovci. The project is valued at around €50 million, with completion planned for 2027.
According to the statement, the project includes the installation of 400 kV and 110 kV switchyards, construction of a 400/110 kV transformer unit (2 x 300 MVA), a control building, relay cabins, auxiliary power facilities, and complete development of the substation plateau with access roads and supporting infrastructure.
The contract was signed with a consortium of contractors, while equipment for the key components—such as transformers, protection systems, local control equipment, auxiliary power and measurement equipment, telecommunications systems, and high-voltage equipment—is currently being procured or delivered.
EMS emphasized that the Belgrade 50 substation, together with the planned double-circuit 400 kV transmission line linking it to the South Banat region, represents a crucial part of the BeoGrid 2025 project and one of the main pillars of Serbia’s future transmission system development.
Construction works on two single-circuit 400 kV overhead lines intended to connect Line No. 450 to the future substation began in September this year. The overall BeoGrid 2025 project is valued at €204 million and includes the substation, transmission lines, and an energy cable system.
The investment is part of the broader “Northern Electricity Transmission Corridor” project, which will form a new transmission route enabling efficient and uninterrupted integration of electricity from the South Banat region—a region with exceptionally high renewable energy potential.
Reliable integration of these renewable sources into the grid depends on the timely construction of new transmission capacities, making the BeoGrid 2025 project critical, EMS noted.
The project will also significantly improve supply reliability for consumers in Srem and Belgrade, which is especially important given the rapid development of these areas and numerous state-level projects underway.
Additionally, BeoGrid 2025 has been recognized as a key source of backup power for the upcoming EXPO 2027 international exhibition.
