Serbia Faces CBAM Pressure Over Verification of Renewable Electricity in EU Trade

Carbon Border Adjustment Mechanism is increasingly being viewed as a structural constraint on electricity-linked exports from the Western Balkans, according to comments published in an interview with Politika by Amalija Pavić, Deputy Executive Director of the American Chamber of Commerce in Serbia.

The remarks highlight growing concerns that the EU carbon border framework is moving beyond a regulatory instrument and becoming a central factor in electricity trading, industrial exports, financing decisions, and contract structuring for companies linked to the EU market.

Electricity classification emerges as central CBAM dispute

Electricity has become the most technically sensitive element of CBAM implementation across carbon-intensive sectors including steel, aluminium, cement, fertilisers, hydrogen, and electricity itself.

The regulation aims to align imported goods with carbon costs under the EU Emissions Trading System. Electricity markets present structural measurement challenges, as renewable and fossil-generated power are physically indistinguishable once transmitted through shared grid systems. This has led to the use of default emission factors and strict conditions for reporting actual emissions within CBAM rules.

Business organisations in Serbia and the wider Western Balkans argue that this approach risks placing electricity from renewable sources in the same regulatory category as fossil-based generation when credible verification pathways are not established.

Investment impact on renewable electricity and export chains

The current CBAM structure is described as creating investment uncertainty for renewable electricity projects in Serbia and the wider region. Stakeholders argue that if renewable electricity delivered through power purchase agreements is treated equivalently to fossil-based supply under default emission rules, incentives for long-term green electricity contracts may weaken.

The issue affects multiple segments of the energy market, including electricity producers, renewable developers, industrial exporters, traders, and project financiers. The dominant electricity utility, EPS, which operates a coal-heavy generation portfolio, is identified as being particularly exposed under any CBAM-linked electricity exposure scenario.

Verification gap between contracts and physical electricity flows

The debate focuses on the absence of a universally accepted mechanism for distinguishing renewable electricity once it enters the transmission system. Proposed solutions involve combining multiple data sources, including accredited verification, transmission system operator data, distribution system operator records, customs documentation, power purchase agreements, guarantees of origin, and reconciliation of contracted versus generated volumes.

Guarantees of origin systems are already in place in Serbia, but their treatment in EU CBAM procedures remains unresolved, particularly for cross-border electricity flows and regional trading structures.

Power purchase agreements under regulatory scrutiny

Physical power purchase agreements (PPAs) are identified as a potential mechanism for linking renewable generation to industrial electricity consumption under CBAM.

Market structures involving intermediaries, traders, balancing parties, and suppliers complicate the ability to establish direct physical attribution between generation and consumption. Industry stakeholders caution that overly restrictive definitions of eligible PPAs could exclude legitimate renewable transactions, limiting the effectiveness of decarbonisation incentives.

EU position on electricity methodology challenges

The European Commission has acknowledged that electricity represents one of the most complex components of CBAM implementation due to verification and market integration challenges.

The regulatory objective is to distinguish high-carbon and low-carbon electricity supply in a way that is auditable and compatible with regional electricity markets. The Commission has also noted that excessive rigidity could discourage cross-border trade in low-carbon electricity from non-EU countries and reduce incentives for decarbonisation in third-country power systems.

Trade exposure and financing implications

Serbia’s export economy is highly exposed to EU regulatory frameworks, with approximately 70% of exports directed to EU markets. The CBAM framework is increasingly influencing EU importers acting as authorised declarants, who must report embedded emissions and surrender CBAM certificates for covered goods.

This creates a dependency chain linking EU buyers, non-EU producers, electricity suppliers, traders, and financial institutions responsible for project financing. Lenders financing renewable electricity projects are particularly sensitive to whether contractual “green value” can be maintained through documentation, verification, and settlement systems.

Multi-layer compliance structure for electricity exports

Proposed compliance frameworks for CBAM-ready electricity exports include layered documentation systems beginning with contract-level structuring. Power purchase agreements would need to define renewable asset identification, contracted volumes, delivery profiles, metering points, balancing responsibilities, guarantees of origin, and data-sharing obligations.

Operational data from producers would include generation records, metered output, outage reporting, curtailment information, and settlement data. System operator and customs documentation would be required to verify cross-border flows, while accredited verification would provide final certification for CBAM compliance files.

Commercial implications for electricity and industrial exports

Electricity is increasingly viewed not only as a commodity but as a compliance-linked input affecting industrial export competitiveness. Industrial producers exporting CBAM-exposed goods such as aluminium, steel, and fertilisers are expected to prefer electricity supply contracts supported by verifiable emissions data and structured documentation chains.

Renewable producers able to provide full verification packages may gain pricing and contract advantages over suppliers relying on general “green electricity” claims. Traders capable of managing compliance documentation between Serbia and EU markets are expected to gain structural importance within cross-border electricity flows.

Market uncertainty and trade efficiency risks

Industry participants have reported that regulatory uncertainty around electricity classification is affecting liquidity in cross-border electricity trade and distorting regional pricing signals. Renewable developers face increased difficulty in securing project financing when future CBAM treatment of electricity cannot be clearly defined. Industrial exporters risk higher compliance costs or reduced competitiveness if verified low-carbon electricity usage cannot be demonstrated to EU buyers.

Compliance engineering and verification systems development

CBAM readiness is increasingly being treated as an integrated engineering and documentation process covering production systems, electricity procurement, and trade compliance.

A structured FEED (front-end engineering design) approach is being applied to CBAM verification workflows, linking production processes, metering systems, renewable electricity contracts, guarantees of origin, customs documentation, supplier data, and verification interfaces into unified compliance architecture.

This approach is being implemented by systems such as Clarion.Engineer, which develops FEED CBAM Verified procedures for exporters to EU markets. The system is designed to align plant-level electricity data, production inputs, and emissions documentation into a pre-verification structure intended to support CBAM reporting and importer due diligence requirements.
