Belgrade, 26 December 2025

On the session held on 25 December 2025, the Council of the Energy Agency of the Republic of Serbia has adopted a decision granting approval to the Transmission Network Code prepared by the transmission system operator of the Republic of Serbia, EMS AD.

The main reason for adopting the new Transmission Network Code is alignment with the new Energy Law of November 2024, the Decree on the Conditions of Electricity Delivery and Supply, as well as harmonization with European network codes (adapted EU regulations) that have been transposed into the legislative framework of the Republic of Serbia.

This Code is also harmonized with other rules prepared by EMS AD: the Rules for the Connection of Facilities to the Transmission System, the Market Operation Rules, and the Rules on the Suspension and Restart of Market Activities.

The most significant changes compared to the previous code include: the definition of new terms related to system users; further elaboration of chapters related to ancillary services, in particular regarding the role of aggregators as new market participants and cooperation between the transmission system operator and the distribution system operator, all with the aim of ensuring the secure operation of the transmission system; the definition of criteria and methods for the application of operational constraints; and the introduction of a new chapter defining the technical conditions for connection to the EMS AD telecommunications system.
