BELGRADE, Nov. 6 — The European Commission’s customs guidance clarifies how nominated electricity volumes are used in customs declarations involving explicitly allocated transmission capacity, putting the quality of delivery records on the revenue-risk agenda for Serbian renewable projects selling to the European Union.
The guidance does not change the emissions methodology for imported electricity. It highlights the need to identify the EU importer and preserve supporting records for the transaction.
For lenders, the central question is whether a project can realise the electricity price assumed in its financial model. A Serbian wind or solar plant may have a strong resource, an operational grid connection and a signed power purchase agreement (PPA), yet uncertainty over CBAM treatment can affect the value of electricity delivered to an EU buyer when the contract price assumes verified actual emissions.
If a transaction does not meet the eligibility conditions, the importer may have to use Serbia’s national default emissions factor of 1.041 tCO2/MWh. Combined with the third-quarter 2026 CBAM certificate price of €82.32 per tonne, that factor implies an indicative unadjusted carbon amount of €85.70/MWh.
The indicative amount is not a fixed charge on every Serbian renewable electricity export. It illustrates the potential difference between a qualifying low-emissions transaction and one assessed using the default factor.
The contract determines who bears that difference. An EU buyer may be responsible for CBAM compliance, while a Serbian generator could face a lower realised electricity price, a disputed warranty or reduced demand if the expected treatment cannot be substantiated.
Contracts and delivery records
Lenders should distinguish a standard electricity offtake agreement from a PPA priced to reflect an expected CBAM advantage. Where the price depends on that advantage, the contract needs provisions for data access, metering, nomination records, verifier cooperation and responsibility if evidence is missing or a claim is rejected.
Technical due diligence should establish whether settlement meters and SCADA systems can produce complete hourly records, whether generation can be allocated to specific contractual volumes, and whether the relevant cross-border nominations can be obtained from the parties controlling them.
Legal and commercial reviews should identify the transmission-capacity holder, the party submitting nominations and the authorised EU CBAM declarant. They should also test whether the PPA remains bankable if an intermediary changes or the buyer can no longer use actual emissions.
Testing project revenues
Lenders should model a downside case using a lower export price or an alternative domestic route to market, without assuming the full CBAM-related premium. Carbon prices, transmission costs, balancing exposure and the availability of eligible import arrangements should be stress-tested together.
Not every Serbian renewable project faces this risk. Domestic sales and export arrangements that do not rely on plant-specific CBAM treatment have different exposures, while additional diligence is most relevant when EU-linked revenues support debt service or a higher project valuation.
For projects relying on EU-linked revenues, CBAM readiness is becoming part of revenue due diligence rather than a separate environmental certification exercise. The bankable asset therefore includes not only the generating plant but also a reliable contractual and data chain linking its output to the EU buyer.
