EU carbon border tax begins reshaping Serbia’s power exports and industrial competitiveness

The introduction of the European Union’s [[PRRS_LINK_1]] at the start of 2026 is already materially altering the economics of [[PRRS_LINK_2]], with the country’s electricity sector—dominated by coal-fired generation—emerging as one of the most immediately exposed segments.

What initially appeared as a regulatory adjustment tied to EU climate policy is now translating into real-time market exclusion, most visibly in the case of Elektroprivreda Srbije (EPS), whose electricity exports to the EU have effectively halted since January.

Electricity exports collapse under carbon cost pressure

The most immediate and quantifiable effect has been the disappearance of Serbian electricity from EU markets.

Since 1 January 2026, EPS has not exported electricity to the European Union, as the carbon adjustment embedded in CBAM pricing has rendered Serbian power uncompetitive.  

At current carbon price levels of roughly €75–90 per tonne of CO₂, and with Serbia’s coal-heavy generation emitting around 1.0–1.1 tCO₂/MWh, the additional CBAM burden reaches approximately:

• €70–80 per MWh of exported electricity  

This effectively doubles the marginal cost of Serbian coal-based power when entering EU markets, eliminating arbitrage margins even during peak price periods.

In practical terms, electricity exports—which historically served as a balancing and profitability mechanism for EPS—have been reduced to zero.

EPS financial exposure and structural risk

The loss of export capability is not just a short-term trading issue; it strikes at the financial core of Serbia’s power system.

Electricity exports, while accounting for less than 10% of total output, have historically contributed disproportionately to EPS profitability by monetising surplus generation during off-peak periods.  

Estimates from Serbia’s Fiscal Council indicate:

• ~€200–300 million annual CBAM-related cost exposure (2026–2030)  

• Potential ~€200 million annual profit erosion tied directly to lost export margins  

More critically, under a full alignment with the EU Emissions Trading System (ETS) by 2030, the cost burden could escalate dramatically:

• Up to €3 billion annually in carbon costs for the power sector  

This creates a binary strategic dilemma: either absorb CBAM penalties at the border or internalise carbon pricing domestically at significantly higher system-wide cost.

Industrial spillover: Early signs of export compression

The CBAM shock is not confined to electricity. Early data suggest a rapid transmission into Serbia’s broader industrial base.

Energy-intensive sectors—including steel, aluminium, cement and fertilisers—are already experiencing:

• ~27–30% decline in exports to the EU in early 2026  

Although CBAM is formally paid by EU importers, the economic reality is different. The carbon cost is effectively passed back through:

• Lower contract prices

• Reduced demand

• Loss of market share

This mechanism erodes competitiveness across Serbia’s export-oriented industrial chain.

Carbon intensity as the core constraint

The underlying issue is structural rather than cyclical.

Serbia’s power generation remains heavily dependent on lignite, resulting in emission intensities significantly above EU benchmarks. In some cases, Serbian electricity is produced with three to four times higher CO₂ intensity than EU averages.  

CBAM effectively monetises this gap.

Under the new regime, exported electricity becomes a two-part price structure:

• Base electricity price

• Carbon adjustment indexed to EU ETS

This fundamentally alters the competitive landscape, particularly for countries outside the EU carbon pricing system.  

Energy system isolation risk

One of the more critical strategic concerns raised by economists and policymakers is the risk of Serbia becoming an “energy island” within the European system.

If current dynamics persist:

• Electricity exports to the EU remain structurally blocked

• Cross-border trading loses economic viability

• Market coupling with EU power exchanges becomes less effective

This isolation would reduce system flexibility, increase balancing costs, and ultimately translate into higher domestic electricity prices.

Policy response gap and transition pressure

The speed of CBAM’s impact highlights a widening gap between Serbia’s current energy structure and EU regulatory alignment.

Key constraints include:

• Slow deployment of renewable capacity

• Delayed coal phase-out strategy

• Absence of a domestic carbon pricing system

• Limited access to EU decarbonisation funds

Without accelerated reform, Serbia faces a dual burden:

• Short-term export losses under CBAM

• Long-term systemic costs under ETS integration

Cost pass-through and domestic price risks

The loss of export revenues and rising compliance costs are likely to feed back into the domestic market.

Scenarios discussed by policy analysts include:

• Electricity price increases for households of up to ~50% under CBAM-adjustment scenarios  

• Potential doubling of prices under full ETS cost internalisation post-2030  

This creates a politically sensitive trade-off between:

• Maintaining artificially low domestic tariffs

• Funding decarbonisation and system modernisation

Strategic outlook: From exporter to transition system

CBAM is effectively forcing a redefinition of Serbia’s position in the European energy market.

The country is moving from:

• A price-driven electricity exporter

towards

• A carbon-constrained system requiring structural transformation

In the near term, the loss of export capability is already visible. In the medium term, competitiveness across industrial sectors will increasingly depend on access to low-carbon electricity.

The long-term trajectory will hinge on Serbia’s ability to:

• Accelerate renewable deployment

• Introduce carbon pricing mechanisms

• Integrate with EU electricity markets

• Attract capital into grid and generation modernisation

Until then, CBAM will continue to act not just as a tax—but as a binding constraint on Serbia’s external economic model, reshaping trade flows, energy strategy, and industrial positioning across the decade.
