Serbia’s planned coupling with the European Union electricity market is now more likely to occur in the first quarter of 2029 than in early 2028, according to SEEPEX executive director Miloš Mladenović. The revised timetable is described as pushing the process back by about a year from an earlier 2028 target. The change extends the period in which Serbian generators and traders remain outside full EU market integration as CBAM affects cross-border electricity trade.
Market coupling is presented as more than a technical reform because it shapes how available cross-border capacity is allocated. It also influences how closely Serbian prices converge with neighbouring EU markets and how electricity moves across borders without relying on separate auction arrangements. For Serbia, the relevance of these effects is linked to accelerating wind, solar and battery development.
Serbia 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. The pipeline increases the need for access to a larger regional market able to absorb surplus generation and balance intermittent output.
CBAM implications for a later coupling date
The revised timetable is also described as having 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. It also prolongs the period during which Serbian electricity exporters must manage carbon-related evidence, importer obligations and cross-border commercial risk without full market integration.
The CBAM-related effects are described as applying to both conventional and renewable generation. For lignite-heavy production, CBAM is described as creating a carbon-cost disadvantage. For renewable power, green electricity can potentially support lower actual-emissions treatment only when backed by required contractual, metering and verification evidence.
The material also states that renewable electricity is not automatically protected because it is physically low-carbon. Instead, it depends on whether supporting evidence requirements are met. This affects how trading arrangements interact with emissions treatment under CBAM coverage for non-member imports.
Trading, congestion risk and storage value
For power traders, delayed coupling is described as preserving 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 this can create trading opportunities, it also increases hedging and scheduling risk.
As Serbia expands interconnection capacity and develops new transmission corridors, commercial value is described as depending on whether regulatory alignment and market-coupling arrangements keep pace. A stronger grid without timely market coupling is described as improving physical security while leaving part of the economic value of integration unrealised. The same linkage is described for storage projects.
Batteries are described as becoming more valuable when they can respond to regional price differences and balancing needs across a deeper market. Delayed integration is said to limit that optionality and keep project revenues more dependent on Serbia’s domestic market structure. This connects storage economics to timing of regional market access.
Execution speed versus legal framework
The main risk highlighted is not framed as a lack of legal framework or political intent to integrate. Instead, it is described as execution speed across multiple workstreams. Transmission upgrades, regulatory alignment, verification procedures and market-coupling arrangements are said to need to progress in parallel while CBAM obligations are already affecting electricity trade.
This timing pressure is described as narrowing the margin for delay beyond 2029. The material 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 appearing through wider basis risk, more complex CBAM compliance and a weaker commercial route for generation being developed in Serbia.
