From 1 January 2026, the definitive EU CBAM regime requires importers of covered goods to declare embedded emissions and surrender CBAM certificates linked to the EU ETS price. The current CBAM scope covers iron and steel, aluminium, cement, fertilisers, hydrogen and electricity. Electricity is therefore treated not only as an industrial input cost but as a regulated carbon-data component of cross-border trade. (Taxation and Customs Union)
For industrial exporters, electricity procurement increasingly forms part of the product’s commercial identity. Exports of a tonne of steel, aluminium, cement or fertiliser to the EU will be assessed not only on price and quality, but also on the credibility of the electricity data used in production. This shifts part of the CBAM burden upstream from the industrial buyer to the electricity supplier. Power producers are therefore asked to support buyer reporting with metering data and contractual evidence.
Electricity suppliers as compliance counterparties
Renewable generators are no longer selling only MWh in this context. They are expected to provide information such as metering data, production timing, contractual traceability and delivery evidence. Buyers’ CBAM positions also rely on guarantees of origin or equivalent registry instruments, PPA documentation and audit-ready emissions information.
Renewable electricity can become a preferred supply for industrial buyers exposed to CBAM because it can reduce indirect-emissions exposure and support a lower-carbon production profile. However, the advantage depends on technical documentation capability. A renewable producer that cannot provide reliable technical documentation may lose commercial value compared with a supplier able to deliver a structured CBAM data package.
CBAM obligations for electricity flows into the EU
The Energy Community has warned that CBAM will affect generation mix, electricity flows, arbitrage options and the profitability of generation assets in contracting parties exporting electricity to the EU. Electricity imports from Energy Community markets into the EU are subject to CBAM from 1 January 2026, bringing administrative and financial obligations. This places CBAM within power-market operations rather than limiting it to customs or industrial policy.
In Serbia and the wider Western Balkans, industrial buyers are expected to require electricity supply structures that can withstand scrutiny from EU importers, authorised CBAM declarants, verifiers and internal auditors. A standard corporate PPA is described as insufficient for these requirements. Contracts are expected to include CBAM clauses covering data delivery, meter boundaries, production allocation and time matching.
Contract terms and audit-ready evidence for traded power
The contract framework is also expected to address non-double-counting, registry evidence, audit cooperation, correction rights and liability for inaccurate declarations. This changes how sellers participate in cross-border transactions by making them compliance counterparties. Sellers are expected to provide regular datasets linking supplied electricity to the buyer’s production period and production process.
For exporters of aluminium, steel, fertilisers or cement, the key question becomes whether they can demonstrate that an electricity claim is technically consistent, contractually supported and verifiable. In markets with active trading, balancing and cross-border flows, linking these elements is described as a complex data-management task.
Documented low-carbon supply versus default values
The CBAM rules create a distinction between generic market electricity and documented low-carbon supply. Default values may be easier to apply but can fail to reflect actual decarbonisation in a country’s generation mix or the specific low-carbon electricity contracted by an industrial buyer. Eurelectric has warned that default-value approaches for electricity can distort cross-border flows and fail to capture actual carbon content of traded power where renewable deployment is rising.

Renewable producers are therefore expected to prepare before explicit buyer requirements appear. A CBAM-ready supplier should have structured systems for SCADA and metering records, generation certificates, settlement data and balancing-period allocation. Additional elements include PPA delivery schedules, grid-connection documentation, buyer allocation methodology and monthly reporting packs.
The strongest producers are described as creating a CBAM data room containing standardised evidence that can be provided to industrial buyers, EU importers and verifiers without reconstructing information later. In practical terms, this supports movement toward CBAM-verified electricity supply in reporting chains rather than simple marketing claims about certification. For renewable generators, this is framed as a bankability issue tied to lenders’ assessment of projects with credible CBAM-compliant offtake frameworks.
Serbia’s role in dual-market renewable projects
For Serbia specifically, its industrial base includes sectors exposed to CBAM and suppliers linked to EU value chains while its power system remains exposed to a carbon-intensive legacy mix. New renewable projects are described as able to serve two markets: the wholesale electricity market and the industrial decarbonisation market linked to export compliance needs. The second market may increase in value over time because CBAM converts clean electricity into a tool for protecting export margins and reducing embedded-emissions exposure while preserving access to EU buyers.
The implications for power producers are described as requiring readiness across engineering, commercial and data-governance functions rather than relying on renewable generation alone. Producers are expected to prove where, when and under which contractual framework electricity was produced, delivered and allocated. In the next phase of the SEE electricity market, producers able to combine renewable generation with reliable offtake arrangements, metering discipline, contractual traceability and audit-ready CBAM documentation are highlighted as positioned differently in contracting outcomes.
