Belgrade has commissioned a new 110/35 kV Beograd 44 substation in Surčin, strengthening the city’s electricity distribution network. The infrastructure is intended to support rising power demand tied to the EXPO 2027 development and surrounding urban expansion.
Construction timeline and investment delivered by Elnos
The facility was completed in one year of construction and represents an investment of around €23 million. The project was delivered by Elnos as part of broader efforts to expand and modernize Belgrade’s power infrastructure ahead of several major upcoming developments.
Role in supplying EXPO 2027 and related grid upgrades
The new substation is expected to become one of the key electricity supply points for the future EXPO 2027 complex. It is also designed to support planned energy infrastructure connected to the project, including the upcoming Beograd 58 – National Stadium substation. Alongside this, other associated distribution upgrades are planned.
Technical configuration and automation features
The Surčin facility is equipped with two transformers rated at 31.5 MVA each. It more than doubles available distribution capacity in this part of Belgrade, improving local grid reliability and flexibility.
The substation uses Siemens technology and operates as a fully automated installation with remote control capabilities from a central dispatch center. According to distribution system operator EDS, advanced technical solutions have reduced the physical footprint of the site compared with a conventional substation of comparable capacity.
