Serbia’s planned coupling with the European Union electricity market is now more likely in the first quarter of 2029 than in early 2028, according to SEEPEX executive director Miloš Mladenović. The change extends the period in which Serbian generators and traders operate outside full EU market integration. The shift also coincides with the Carbon Border Adjustment Mechanism affecting cross-border electricity trade.
Coupling timetable pushed from 2028 to 2029
Mladenović said the first quarter of 2029 is a more realistic timetable, effectively moving the process back by about a year from an earlier 2028 target. Market coupling is described as shaping how available cross-border capacity is allocated and how closely Serbian prices align with neighbouring EU markets. It also affects how electricity moves across borders without relying on separate auction arrangements.
The delay is framed as increasingly relevant as wind, solar and battery development accelerates in Serbia. The country has around 11 GW of wind and solar projects in the transmission connection process. EMS has signed connection contracts covering roughly 2 GW of battery storage.
CBAM implications for exporters and compliance timelines
The revised coupling timetable has direct implications for the EU’s Carbon Border Adjustment Mechanism. Electricity imported into the EU from non-member countries is covered by CBAM, with only limited routes toward exemption for markets that achieve deep integration with the EU electricity system and meet regulatory conditions. Market coupling is identified as one of the core elements of that integration process.
Serbia has transposed significant parts of the EU electricity package and is moving through Energy Community verification and market-reform procedures. However, shifting from 2028 into 2029 leaves less time before the 2030 CBAM review horizon. During that extended period, Serbian electricity exporters are expected to manage carbon-related evidence, importer obligations and cross-border commercial risk without full market integration.
Effects on generation types and trading risk
The CBAM-linked timing is described as having consequences for both conventional and renewable generators. For lignite-heavy production, CBAM creates a carbon-cost disadvantage. For renewable power, green electricity can potentially support lower actual-emissions treatment, but only when backed by required contractual, metering and verification evidence.
The source also notes that renewable electricity is not automatically protected solely because it is physically low-carbon. For power traders, delayed coupling preserves a more fragmented market structure. Serbia remains exposed to separate cross-border capacity allocation, basis risk between SEEPEX and neighbouring exchanges, and periods when congestion prevents price convergence.
While separate structures can create trading opportunities, they are also linked to higher hedging and scheduling risk. As Serbia expands interconnection capacity and develops new transmission corridors, the commercial value of those investments depends on whether regulatory alignment and market-coupling arrangements keep pace. A stronger grid would improve physical security but may leave part of the economic value of integration unrealised if coupling does not arrive on time.
Storage value tied to deeper regional integration
The same linkage is described for storage projects. Batteries are said to become more valuable when they can respond to regional price differences and balancing needs across a deeper market. Delayed integration limits that optionality and keeps project revenues more dependent on Serbia’s domestic market structure.
Execution speed becomes the central risk for 2029
The main risk is described as shifting away from legal framework or political intent toward execution speed. Transmission upgrades, regulatory alignment, verification procedures and market-coupling arrangements are expected to need to progress in parallel while CBAM obligations are already affecting electricity trade. This reduces the margin for delay.
The source states that Serbia’s power sector is adding renewable capacity and storage faster than it is integrating with the market most relevant for exports. If coupling slips further beyond 2029, the cost is described as extending beyond regulatory impacts into wider basis risk, more complex CBAM compliance and a weaker commercial route for generation Serbia is building.
