The European Commission has set the third-quarter 2026 CBAM certificate price at €82.32 per tonne of CO₂, up from €75.28 in the second quarter. Using Serbia’s default emissions factor of 1.041 tCO₂/MWh, the indicative CBAM burden for imports where the default value is applied is about €85.70 per megawatt-hour in Q3. The same calculation implies roughly €78.37/MWh in Q2, an increase of more than €7/MWh over three months.
CBAM default cost and implications for cross-border pricing
For Serbian electricity traders, CBAM is increasingly treated as part of the cross-border price calculation rather than a separate compliance charge. An export deal that looks profitable when comparing Serbian and EU wholesale prices can become uneconomic once the default carbon cost is added. At the Q3 certificate price, relying on the national default starts from an indicative carbon disadvantage of around €85.70/MWh, which is described as large relative to normal wholesale-market spreads.
The higher burden does not indicate that all Serbian electricity physically carries emissions at that level. Serbia’s generation mix includes hydro, wind and solar alongside lignite-fired production. The key issue for individual renewable generators is methodological, because the system applies the prescribed default value unless conditions for using actual emissions are met.
Actual-emissions methodology depends on a qualifying evidence chain
A Serbian wind farm cannot replace the national default by demonstrating renewable output alone under the current EU framework. Electricity claimed under actual emissions must be supported by a qualifying power purchase agreement between the authorised CBAM declarant and the third-country producer. The generating installation must meet relevant emissions threshold and physical network conditions.
In addition, electricity must be firmly nominated to allocated cross-border capacity, with nomination and production matched within a period of no more than one hour. Compliance must be certified by an accredited verifier, supported by interim evidence during the reporting period. The operational chain described links a named installation through meter and SCADA data, hourly generation, PPA allocation, accepted nomination, cross-border evidence, the EU declarant and final verification.
Verification requirements affect trading and contract design
For renewable generators, commercial value increasingly depends on maintaining evidence needed to show that the specific electricity claimed by an EU importer came through a qualifying transaction. A producer that fails to preserve hourly meter records, nominations or contractual allocation could lose access to actual emissions and leave its EU buyer exposed to the higher Serbian default. The higher Q3 certificate price increases the economic consequences of such failures.
The evidence expectations extend to meter hierarchy, SCADA-to-settlement reconciliation, calibration records and hourly production data, as well as trading records. Even if renewable electricity is exported successfully from a market perspective, it may still be difficult to demonstrate that nominated cross-border quantities correspond with output from the named installation during the required hourly interval. For projects planning to use actual emissions for 2026 imports, preserving the complete evidence chain during 2026 is identified as increasingly important.
The carbon-price increase also strengthens the case for changes in how renewable PPAs are drafted. A conventional PPA typically covers price, volume, profile, balancing, settlement and guarantees of origin, while a CBAM-oriented agreement needs additional controls including plant identification and allocation of qualifying volumes. It also requires EU declarant identification, access to meter and nomination information, verifier cooperation, data-retention requirements and provisions preventing double counting.
The agreement should also specify what happens if electricity fails the actual-emissions test. If contract pricing assumes low or near-zero plant-specific emissions but verification fails and the importer must use Serbia’s default, carbon exposure could become material. The parties therefore need to determine contractually who carries fallback risk.
Guarantees of origin remain separate from CBAM actual-emissions claims
The rising CBAM certificate price reinforces a distinction between guarantees of origin and actual-emissions verification under CBAM rules. A Serbian wind or solar generator may issue renewable certificates associated with its production, which can carry commercial value and could become more valuable if EU recognition of Energy Community guarantees of origin expands. However, guarantees of origin do not replace physical electricity evidence required under CBAM.
The certificate can establish a renewable attribute but does not establish the PPA terms, transmission conditions, cross-border nomination or hourly matching needed to claim actual emissions for imported electricity. As a result, Serbian renewable projects are described as potentially selling two distinct environmental products: a renewable attribute and a CBAM-verifiable electricity transaction.
Industrial buyers and financing considerations
The same evidence issue applies to Serbian industrial companies purchasing renewable electricity and exporting CBAM-covered goods into the EU. Industrial buyers increasingly seek PPAs that reduce both electricity-price exposure and production-related carbon footprint exposure in their downstream reporting needs. A generic green-electricity contract may not provide evidence required for regulatory actual-emissions claims.
Buyers are described as seeking access to meter data, production allocation and verification documentation when renewable procurement is intended to support downstream carbon reporting. This could support demand for domestic supply of CBAM-ready renewable electricity among steel, aluminium and other energy-intensive exporters where such documentation can be provided alongside transactions.
The development is also linked to project financing considerations because renewable developers have traditionally modelled revenue around wholesale prices, PPA prices, balancing costs, curtailment and guarantees of origin. CBAM adds another possible source of value because a project capable of delivering verifier-ready electricity to an EU buyer can potentially avoid a default carbon charge approaching €86/MWh based on the figures cited for Q3.
The Commission calculates CBAM certificate prices from EU ETS auction prices: for 2026 they are set quarterly and from 2027 on a weekly basis. That structure means carbon-price volatility becomes increasingly embedded in cross-border electricity economics. For Serbia’s exports relying on default emissions this increases effective costs reaching the EU market when EU ETS prices rise.
The Commission confirms Q3’s €82.32/tCO₂ certificate price versus €75.28 in Q2 and Serbia’s applicable default factor of 1.041 tCO₂/MWh. The resulting Q2 comparison is supported by Energy Community CBAM monitoring, while current EU regulation retains requirements covering physical PPA arrangements, network conditions, nomination procedures, hourly matching and accredited-verifier certification for actual electricity emissions.
