Serbia’s planned coupling with the European Union electricity market is now more likely to take place in the first quarter of 2029 than in early 2028, according to SEEPEX executive director Miloš Mladenović. He said the updated timetable effectively pushes the coupling process back by about a year from the earlier 2028 target. The change extends the period during which Serbian generators and traders remain outside full EU market integration as CBAM raises the cost of cross-border electricity trade.
Coupling timetable and implications for cross-border trade
Mladenović said the first quarter of 2029 is a more realistic schedule for market coupling. Market coupling affects how available cross-border capacity is allocated, how closely Serbian prices converge with neighbouring EU markets, and how easily electricity can move across borders without relying on separate auction arrangements. The delay is relevant as wind, solar and battery development accelerates in Serbia.
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. This pipeline increases the need for access to a larger regional market able to absorb surplus generation and balance intermittent output.
CBAM coverage and compliance timing
The revised timetable also has 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 relevant regulatory conditions. Market coupling is described 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 prolongs the period in which Serbian electricity exporters must manage carbon-related evidence, importer obligations and cross-border commercial risk without full market integration.
Effects on generators and trading risk
The CBAM-linked delay has consequences for both conventional and renewable generators. For lignite-heavy production, CBAM creates a carbon-cost disadvantage. For renewable power, green electricity may support lower actual-emissions treatment only when backed by required contractual, metering and verification evidence.
Renewable electricity is therefore not automatically protected solely because it is physically low-carbon. For power traders, delayed coupling preserves a more fragmented market structure in which Serbia remains exposed to separate cross-border capacity allocation. The delay also keeps basis risk between SEEPEX and neighbouring exchanges and periods of congestion that prevent price convergence.
The fragmented setup can create trading opportunities while also increasing 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 architecture keep pace with physical buildout. A stronger grid would improve physical security but could leave part of the economic value of integration unrealised if coupling does not arrive on time.
The same pattern applies to 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 limits that optionality and keeps project revenues more dependent on Serbia’s domestic market structure.
Execution speed versus legal framework
The main risk highlighted is not a lack of legal framework or political intent to integrate but execution speed. Transmission upgrades, regulatory alignment, verification procedures and market-coupling arrangements must move in parallel while CBAM obligations are already affecting electricity trade. This narrows the margin for delay as Serbia’s power sector adds renewable capacity and storage faster than it integrates with the export-relevant market.
If coupling slips further beyond 2029, the cost would extend beyond regulatory impacts into wider basis risk, more complex CBAM compliance, and a weaker commercial route for generation Serbia is building for exports.
