Serbia’s electricity trade with the European Union is facing a potential carbon liability of €85.70 per megawatt-hour, increasing pressure on export margins, power purchase agreements and investment returns for renewable energy projects. The cost arises from the EU’s Carbon Border Adjustment Mechanism (CBAM), which applies a national default emissions factor to Serbian electricity imports unless the requirements for alternative treatment are met.
The mechanism is changing the commercial conditions for electricity exports by adding carbon intensity, contractual arrangements and verified emissions data to the factors determining competitiveness. Wholesale prices, available cross-border transmission capacity and generation costs alone are no longer sufficient to establish whether an export transaction is commercially viable.Serbia’s national CBAM default emissions factor is 1.041 tonnes of CO₂ per MWh. Applying the EU’s third-quarter 2026 CBAM certificate price of €82.32 per tonne of CO₂ produces an indicative gross carbon liability of €85.70/MWh for electricity imports assessed using that factor.
This calculation reflects the third-quarter certificate price and does not establish the charge applicable to October deliveries, which will be determined using the fourth-quarter price. Eligible carbon costs paid in the country of origin may also reduce the final liability. Unlike steel and aluminium, imported electricity does not receive a free-allocation adjustment under CBAM.
Serbian-Hungarian Power Trading Faces a Carbon Cost Gap
The difference between electricity prices in Serbia and Hungary illustrates the pressure on conventional export economics. For delivery, day-ahead prices on the SEEPEX electricity exchange reached €239.96/MWh, while Hungary’s HUPX market recorded €269.43/MWh.
The resulting price spread of €29.47/MWh was substantially below the indicative Serbian carbon liability of €85.70/MWh. An electricity export from Serbia to Hungary assessed using the national default emissions factor would therefore struggle to produce a positive trading margin at those average prices, even before accounting for transmission capacity, balancing and transaction costs.
Actual results can differ according to hourly price spreads, contractual positions and independently verified emissions. Nevertheless, higher Hungarian wholesale prices do not automatically translate into profitable export opportunities for Serbian electricity suppliers under the new carbon regime.
The Energy Community Secretariat has documented changes in regional electricity trading patterns since CBAM was introduced. Commercial exchanges between Western Balkan markets and neighbouring EU countries declined in early 2026, although hydrological conditions, generation availability and changes in demand also affected electricity flows.
Serbia continues to serve as an important northern trading corridor. Scheduled electricity exports towards Hungary increased during the second quarter, indicating that cross-border trade has continued despite the new rules. CBAM has instead altered the economics of transactions and the potential destinations for electricity produced in the country.
EPS and Independent Producers Face Different Export Conditions
For Elektroprivreda Srbije (EPS), the implications extend across its generation and sales activities. Serbia’s reliance on lignite-fired power plants exposes electricity assessed under the national default methodology to substantial carbon costs, weakening its competitiveness in EU markets and increasing the importance of domestic sales, generation flexibility and investment in lower-carbon capacity. Independent renewable energy producers face a different challenge. Although Serbian wind and solar installations can generate electricity with minimal operational emissions, their EU customers cannot automatically claim those emissions solely because the power originated from a renewable facility.
Access to actual-emissions treatment requires a qualifying physical power purchase agreement involving the EU declarant and the electricity producer. The parties must provide evidence of a compliant transmission route, while cross-border capacity nominations must align with generation within hourly intervals. Independent verification is also required, and the generating installation must meet the applicable emissions threshold.
Guarantees of Origin alone do not establish eligibility for actual-emissions treatment. Renewable electricity therefore does not automatically receive a lower CBAM valuation when exported from Serbia. Two wind or solar projects with comparable technology, generation costs and expected output could consequently have different export values depending on whether their contractual, transmission and metering arrangements support compliant deliveries under the mechanism.
CBAM Adds New Criteria to Renewable Energy Financing
For banks financing wind, solar and battery storage projects, the new requirements introduce additional risks into project assessments. Conventional project-finance analysis typically examines construction expenditure, production forecasts, wholesale electricity prices, balancing exposure and the creditworthiness of power buyers. CBAM adds the need to evaluate emissions verification, contractual eligibility, access to export markets and the reliability of projected cross-border revenues.
Lenders should assess projects against separate revenue scenarios covering domestic electricity sales, conventional exports to the EU using applicable default emissions factors, and qualifying exports supported by verified actual emissions. Existing financing arrangements may also require reassessment if debt-service projections depend on electricity price premiums available in Hungary or other EU markets. The ability to secure favourable export treatment becomes a relevant factor in evaluating expected revenues and the capacity of projects to service their debt.
Industrial Exporters Face Sector-Specific Electricity Exposure
Electricity costs also affect Serbia’s steel, aluminium, cement and fertiliser industries. Higher power prices increase manufacturing expenses, but CBAM does not apply identical treatment to purchased-electricity emissions across all covered sectors.
Indirect electricity emissions are included in CBAM calculations for cement and fertilisers. Current obligations for iron, steel and aluminium generally focus on direct embedded emissions. As a result, procuring renewable electricity can improve manufacturing cost competitiveness and customer acceptance without necessarily reducing the immediate CBAM certificate liability of every Serbian industrial exporter.
The European Commission is considering amendments to the electricity CBAM methodology that could improve recognition of lower-carbon generation. However, investment decisions cannot assume that the proposed changes will be adopted in their current form. For Serbia’s electricity producers, traders and industrial consumers, the ability to connect generation, trading infrastructure and independently verifiable carbon data is becoming increasingly important to market access.
The country’s generation potential, regional interconnections and expanding renewable portfolio provide the basis for continued participation in regional electricity trade. Capturing European market premiums will increasingly depend on demonstrating which generating installation produced the electricity, when it was generated, how it crossed the border and which EU importer is entitled to claim its emissions. Without the required evidence, Serbian renewable electricity risks being valued at the EU border according to the carbon intensity of the wider national power system rather than the emissions of the individual generating installation.
