Frequently Asked Questions

  • Should customs duties be paid for import/export of electricity in/from the Republic of Serbia?
    This is an issue in the domain of the relevant customs authorities rather than the responsibility of AERS. Based on the Energy Community Treaty, ratified in 2006, the Republic of Serbia assumed the responsibility to abolish custom duties and limitations on import and export quantities of electricity and gas for countries the EC Treaty applies to
  • Do I have to pay for the transit of electricity through the transmission network of the Republic of Serbia? How can I book the transmission capacity on interconnected power lines in the Republic of Serbia?
    PE “Elektromreza” (EMS) as the transmission system operator and electricity market operator in Serbia is responsible for the allocation of rights to use the available cross-border transmission capacities on interconnected power lines within the Serbian power system. Preliminary rules for allocation of rights to use available cross-border transmission capacities on interconnections of the Republic of Serbia, based on the market principle as an explicit auction on a monthly basis, are available on the PE EMS website (www.ems.rs).
  • Under Article 10.1.3 of the “Rules on Cross-border Transmission Capacity Allocation of the public enterprise for electricity transmission and transmission system management „Elektromreza Srbije“ (PE EMS) for PE EMS control area borders for the period 01/01 – 31/01/2012”, curtailment might take place "due to the scheduled annual disconnections of the cross-border interconnection lines for regular maintenance, due to Force Majeure or other unplanned/unforeseen events in the electric power system." This notion of "unplanned/unforeseen events” is not defined in the rules and could cover a broader category of events for which curtailment might be possible, and there is a risk that it might go beyond the "emergency situations where the transmission system operator must act in an expeditious manner and re-dispatching or countertrading is not possible" which are in fact the only possibility for curtailment allowed by the Regulation 1228/2003 (Article 6(2)). Please clarify the notion of "unplanned/unforeseen or unscheduled events" (other than Force Majeure) in Articles 10.1.3, 10.1.7 and 10.2.3 of the Allocation Rules for 2012.
    The current wording of these Articles does not give any grounds or possibility for curtailiment outside of what Article 6(2) of Regulation 1228/2003 foresees as the only applicable reason ("emergency situations where the transmission system operator must act in an expeditious manner and redispatching or countertrading is not possible"). This clearly comes out of the stipulation of Article 10.3 of the Allocation Rules, which was introduced on the insisting of AERS. In the spirit of avoiding any doubt in this respect, albeit only lingual, we shall focus our efforts on reformulating the provisions of the abovementioned Articles in the Allocation Rules for 2013.
  • Article 10.1.8 of the “Rules on Cross-border Transmission Capacity Allocation of the public enterprise for electricity transmission and transmission system management „Elektromreza Srbije“ (PE EMS) for PE EMS control area borders for the period 01/01 – 31/01/2012” provides for a definition of Force Majeure by stipulating that "Force Majeure events and circumstances are those which could not be foreseen, prevented, avoided or eliminated by the measures undertaken to preserve safe and reliable operation of the electric power system, compliant with the Grid Code and which took place after the Allocation Procedure and in particular natural disasters, fires, flood, earthquakes, state of emergency and warlike operations as well as the measures of the state authorities and organizations of the transmission system operators." This definition of Force Majeure includes "measures of the state authorities and organizations of the transmission system operators", which would seem to constitute rather the reactions to an emergency situation than the emergency situation itself. Please specify which measures of the state authorities and organizations of the transmission system operators in Article 10.1.8 of the Allocation Rules for 2012 could be considered Force Majeure. Please clarify if only measures required as an expeditious reaction to emergency situations can trigger capacity curtailment.
    It is notorious that there are various nuances in comparative law (including that of EU Member States and their TSOs) regarding the definition of Force Majeure. Irrespective of this fact, and without opening an unnecessary academic debate on the issue, AERS shall construe the provisions of the Allocation Rules in such a manner that only measures required as an expeditious reaction to emergency situations can trigger capacity curtailment.
