Elektromreza Srbije

What Elektromreza Srbije does

Elektromreza Srbije (EMS AD) is Serbia's state-owned transmission system operator, established in 2005 following the restructuring of the country's electricity sector and wholly owned by the Republic of Serbia. As the sole designated TSO, EMS holds exclusive responsibility for operating, maintaining, and developing Serbia's high-voltage electricity transmission network, and serves as the conduit through which generators, distribution system operators, suppliers, traders, and large industrial consumers access the transmission grid. The company is a member of ENTSO-E and operates within the Energy Community framework, applying EU regulations adapted for the Serbian context.

EMS's core technology stack centers on the SCADA/EMS system for real-time transmission control and monitoring, complemented by the Market Management System (MMS), the DAMAS system for cross-border capacity allocation, the Wide Area Monitoring System (WAMS) for grid stability, the SCALAR lightning detection system, the SRAAMD automated metering system, and an ASSET MANAGEMENT platform for maintenance scheduling. Underpinning these systems is a fiber-optic telecommunication network of over 4,800 km built on optical ground wires with nearly 100 equipped nodes, interconnected with all adjacent TSOs. Corporate operations are run on SAP, recognized with a 2018 SAP Quality Awards gold medal. EMS also operates the EMS Transparency Platform publishing market and operational data per EU Regulation 543/2013.

EMS generates revenue through regulated transmission tariffs, balancing services, and ancillary services charged to system users, with tariffs approved by the Energy Agency of the Republic of Serbia (AERS). The company distributes access to its transmission network on a non-discriminatory basis under the Grid Code and Market Rules, engaging market participants through official portals, public procurement notices, and industry events such as the Belgrade Energy Forum. A significant capital investment cycle is underway, including the EUR 157 million Trans-Balkan Electricity Corridor Phase I (approximately 350 km of 400 kV lines) and the EUR 8 million EXPO 2027 backup supply project, supported by an approved 2023-2032 Development Plan and new Electricity Market Rules effective December 26, 2025.
