Starting January 2026, Serbia’s electricity exports to the European Union will undergo significant changes as the EU implements its Carbon Border Adjustment Mechanism (CBAM). This regulatory framework aims to integrate carbon costs into power pricing, fundamentally altering the landscape of electricity trade in the region.
Currently, Serbia’s energy generation is predominantly reliant on lignite, which constitutes approximately 61% of its energy mix, alongside 5% from gas and over 30% from low-carbon sources such as hydroelectric power. As CBAM comes into effect, Serbian electricity exports will be subject to reporting requirements and financial obligations associated with embedded carbon emissions. This development poses a challenge for Serbia’s export competitiveness, particularly given its high reliance on carbon-intensive generation.
The financial implications of CBAM are substantial. With current EU Emissions Trading System (ETS) allowance prices ranging between €65–95/tCO₂, Serbian electricity exports could incur additional costs of around €65–95/MWh. Even under a system-average emission factor, the carbon cost would still hover between €40–60/MWh. Given that regional wholesale prices are approximately €100/MWh, this carbon cost is poised to significantly diminish profit margins for coal-based electricity exports.
This shift in pricing dynamics indicates that Serbian exports may become increasingly limited to periods of high demand or transactions supported by lower-carbon electricity sources. Consequently, the traditional competitive edge of Serbian coal-based generation as a low-cost export option is likely to erode, necessitating a transition towards carbon-adjusted competitiveness that aligns with EU market standards.
While CBAM does not directly affect electricity imports into Serbia, it exerts upward pressure on import prices due to market coupling with neighboring EU nations. Countries like Romania and Hungary have already integrated full EU ETS pricing into their wholesale electricity markets. As a result, Serbian import prices are expected to increasingly reflect these carbon-inclusive benchmarks rather than solely energy costs.
Recent data highlights this trend: Romania’s day-ahead market averaged approximately €114/MWh in 2025, while Serbia’s annual base price on SEEPEX was around €99/MWh. As carbon pricing becomes more entrenched in regional markets, Serbia’s import parity price is anticipated to rise significantly.
A simplified economic model suggests that if EU carbon costs are partially transmitted into regional prices, Serbian import benchmarks could increase by roughly €15–70/MWh, depending on prevailing market conditions and carbon price levels. This indirect impact underscores the broader economic ramifications of CBAM beyond direct charges.
The dual pressures facing the Serbian market—diminished export competitiveness due to rising carbon costs and increased import expenses—are prompting shifts in trading strategies across the region. Market participants are moving away from straightforward geographical arbitrage towards more sophisticated approaches focused on short-term optimization and carbon-aware portfolio management. Factors such as hourly price fluctuations and renewable energy intermittency are becoming critical drivers of value in this new context.
The demand for traceable low-carbon electricity is also escalating as industrial consumers exposed to EU carbon prices seek renewable-backed supplies through power purchase agreements or guarantees of origin. This trend is fostering a premium market segment for “CBAM-compliant” electricity that can demonstrate reduced emissions.
This evolving landscape signals a clear need for structural investment in Serbia’s energy sector. Enhancing renewable generation capabilities—especially when paired with storage solutions or flexible dispatch options—will be essential not only for maintaining export relevance but also for bolstering industrial competitiveness.
The capacity to deliver verified low-carbon electricity is emerging as a crucial differentiator within regional power markets. Conversely, coal-based generation may continue to find economic viability primarily within domestic markets or non-EU export corridors where stringent carbon pricing has yet to be enforced.
The introduction of CBAM represents a pivotal moment in Southeast Europe’s electricity trading environment. For Serbia, this transition signifies a departure from a volume-driven export model towards one characterized by carbon-adjusted pricing, portfolio flexibility, and enhanced emissions transparency, with far-reaching implications for both trading practices and future investment strategies in the energy sector.
