Serbia’s Renewable Power Gains New CBAM Value Through Verified Electricity Data

Serbia’s renewable electricity market is facing a new commercial requirement as the EU’s Carbon Border Adjustment Mechanism (CBAM) makes verifiable emissions data increasingly important for power exports and industrial supply chains. Two distinct routes are emerging for Serbian renewable generators. Electricity can be sold directly, or through traders, for physical delivery into the EU, or it can be supplied domestically to Serbian industrial companies whose products are later exported to EU markets. Although the same wind, solar or hydro plant can serve both markets, the CBAM treatment differs substantially.

Electricity exports face direct CBAM requirements

When electricity crosses the EU border, electricity itself is the CBAM good. The EU importer or other qualifying authorised CBAM declarant carries the regulatory liability. Electricity is classified under CN 2716 00 00. Under the current rules, embedded emissions are generally calculated using a default value unless the authorised declarant can demonstrate eligibility to use actual emissions.

For Serbian renewable generators, this creates an important distinction between producing low-carbon electricity and being able to prove its emissions at the EU border. Actual-emissions treatment requires cumulative evidence, including a qualifying physical PPA, the required grid relationship between the generating installation and the EU system, generation below the 550 gCO₂/kWh fossil-origin threshold, cross-border nominations aligned with generation at intervals of no more than one hour, and certification by an accredited verifier.

Where transmission capacity is explicitly allocated, the party holding the import capacity and nominating the electricity for import is regarded as the authorised CBAM declarant. Imports must be measured border by border in periods of no more than one hour, without simply netting exports or transit against imported quantities within the same hour.

Serbia has significant exposure to electricity CBAM

The scale of Serbia’s exposure is reflected in European Commission data. About 96 million MWh of electricity were reported as CBAM imports between the fourth quarter of 2023 and the second quarter of 2025. Serbia accounted for approximately 15% of that volume, making it the second-largest source after the United Kingdom and ahead of North Macedonia. Electricity exports to the EU represent roughly 5% of Serbia’s total exports to the bloc.

The definitive CBAM regime has been in force since 1 January 2026, making the ability to substantiate renewable electricity claims increasingly relevant to cross-border power transactions.

A Serbian generator can establish metering records, generation data, installation identification, emissions calculations, PPA documentation, Guarantees of Origin and operating procedures. However, the final actual-emissions claim also depends on the trader or intermediary, transmission and nomination arrangements, the EU importer, the authorised declarant and the accredited verifier. The commercial value therefore extends beyond renewable electricity itself to renewable electricity supported by an intact evidence chain.

Traders are becoming part of the compliance chain

Serbian electricity transactions can involve several parties, including a Serbian supplier, regional trader, cross-border capacity holder, EU trading company and final CBAM declarant. Each additional contractual or operational interface creates another point at which the connection between the generating plant and the electricity claimed at the EU border can be disrupted.

The current implementing rules recognise intermediary structures, but require contractual evidence establishing the relevant relationship between the parties and demonstrating physical delivery rather than merely a financial hedge.

This means conventional virtual PPAs or portfolio-based green power contracts cannot automatically be treated as sufficient evidence for the current actual-emissions route. The European Commission has noted that Serbia already had several PPAs under development representing around 0.3 GW of contracted capacity, while formal cross-border PPAs between EU buyers and third-country generators remained uncommon. The Commission also noted that European corporate PPAs are frequently arranged through intermediaries, while purely financial virtual PPAs do not establish the physical delivery required under the current CBAM route.

Proposed EU changes could alter PPA structures

The European Commission has proposed changes that would explicitly allow PPAs involving intermediaries where a verifiable contractual relationship exists between the generator, intermediary or intermediaries and the importer or authorised CBAM declarant. The proposal would also remove the existing network-congestion criterion and modify nomination requirements. If adopted, the electricity-related changes would apply to imports dating from 1 January 2026.

The amendments are not yet final law. As of 8 September 2026, the European Parliament was still awaiting its first-reading position, with the file scheduled for the plenary beginning 14 September 2026.

For Serbian producers and traders, the proposed changes indicate greater recognition of the structure of wholesale electricity markets, where renewable generation is often sold through intermediaries rather than directly to the final EU declarant. The evidence requirement would remain, with greater emphasis on traceability across the contractual chain.

CBAM evidence extends beyond certificates

A Serbian renewable generator seeking EU customers increasingly needs to provide more than electricity and renewable certificates. The evidence package can include installation identification, technology, meter hierarchy, generation data, emissions methodology, PPA documentation, delivery structure, trader or intermediary roles, nominated quantities, relevant time periods and cross-border import documentation.

These datasets must reconcile. Production volumes, contractual allocations, trader schedules and quantities declared at the EU border must correspond. The European Commission published detailed sector guidance, including dedicated electricity guidance, on 14 August 2026, followed by verifier and accreditation guidance on 24 August. Accredited verifiers have been able to register in the CBAM Registry since 1 September 2026, with the first verification reports expected from January 2027. This makes the quality of 2026 records particularly important. Missing hourly meter data, inconsistent nominations, inadequate PPA structures or undocumented allocations between buyers may create problems when evidence is formally reviewed.

Domestic industrial supply creates a second route

A renewable generator does not have to export electricity directly to the EU to become relevant to CBAM. It can instead sell electricity through a Serbian PPA or supplier arrangement to an industrial company whose products are exported to the EU. In that case, the electricity itself is not the CBAM good. The CBAM good is the Serbian manufactured product imported into the EU.

The treatment of renewable electricity then depends on the CN code and emissions methodology applicable to that product. Under the current Regulation, goods covered by Annex II — principally relevant iron and steel products, aluminium and hydrogen — are currently assessed for direct emissions only. Electricity consumed during their production therefore does not generally reduce the 2026 CBAM obligation simply because the Serbian producer purchased renewable electricity.

For goods where indirect emissions are included, notably relevant cement and fertiliser products, electricity can have a more direct role. The CBAM Regulation permits actual electricity emissions to be used for indirect emissions where the industrial installation can demonstrate either a direct technical connection with the generation source or a qualifying PPA with a third-country electricity producer.

Industrial PPAs require detailed electricity evidence

For PPA-based claims, implementing rules can require evidence including the physical-delivery contract, smart-meter data showing electricity production, smart-meter data demonstrating delivery of an equivalent amount to the industrial installation during the same measurement period of no more than one hour, and evidence of the physical grid connection between the generator and industrial facility. Where an intermediary participates, the contractual structure must meet the applicable CBAM requirements.

This creates a potential Serbian business model in which renewable generators supply domestic industrial companies together with an industrial CBAM electricity evidence package. For a Serbian cement or fertiliser exporter, qualifying renewable electricity data may allow the electricity component of embedded emissions to be calculated using actual data rather than the applicable grid-based default, provided all regulatory conditions are satisfied. The EU importer remains responsible for the CBAM declaration, while the Serbian industrial operator supplies information needed to establish the product’s embedded emissions.

The two evidence chains are therefore distinct:

Serbian RES producer → trader/cross-border delivery → EU electricity importer or authorised CBAM declarant → accredited verifier

and

Serbian RES producer → Serbian industrial installation → exported CBAM product → EU importer/authorised CBAM declarant → accredited verifier.

Guarantees of Origin do not replace CBAM evidence

Guarantees of Origin remain relevant for demonstrating renewable attributes, renewable procurement, disclosure and avoiding double claiming. They do not, however, automatically satisfy CBAM requirements concerning the generating installation, PPA or technical connection, metering and, for electricity exports, physical cross-border matching and nomination. The distinction is therefore between renewable procurement evidence and CBAM emissions evidence.

This is particularly relevant for Serbian industrial buyers that have traditionally relied on supply agreements and renewable certificates to document green electricity procurement. For CBAM purposes, the electricity must be traceable through auditable data to the relevant generation source and, where required, to the industrial process and production period.

CBAM treatment depends on the exported product

Renewable electricity does not create a CBAM benefit for every Serbian exporter. If a Serbian factory produces goods outside the current CBAM scope, purchasing renewable electricity does not bring those products into CBAM or create a CBAM credit. Renewable power can still affect Scope 2 emissions, corporate carbon reporting, product-carbon-footprint requirements, customer procurement standards, financing criteria and voluntary decarbonisation commitments, but those mechanisms are separate from CBAM.

Similarly, for steel or aluminium products currently subject only to direct-emissions treatment, renewable electricity can lower the actual carbon footprint without necessarily reducing the current CBAM calculation. The relevant question is therefore whether the applicable CBAM methodology for the exported CN code allows qualifying electricity data to influence the embedded-emissions calculation.

Renewable electricity could develop different commercial values

Serbia’s renewable market could increasingly distinguish between conventional renewable power and verification-ready renewable electricity. The latter would be supported by contractual and data systems capable of tracing electricity through an EU import transaction or into the production process of an eligible Serbian CBAM exporter. This distinction could influence commercial value. An EU electricity trader facing default Serbian electricity emissions has a different exposure from one able to support verified actual emissions.

Likewise, a Serbian industrial buyer whose electricity-related emissions are included in its CBAM product calculation may place greater value on a supplier capable of providing hourly metering and CBAM-compatible evidence than on a supplier offering certificates alone. The Energy Community has reported that renewable producers and developers are encountering practical difficulties in demonstrating eligibility for actual emissions and that the requirements are creating additional compliance costs. It has also reported unusual movements on the Serbia-Hungary electricity corridor during 2026 as CBAM begins influencing regional trade economics.

For Serbian renewable generators, participation in the EU-facing market therefore increasingly depends on both electricity production and the ability to make that production auditable. For direct EU exports, the evidence system must connect the generating installation with the trader, border transaction and authorised CBAM declarant. For domestic industrial supply, it must connect renewable generation with the Serbian consuming installation and, where indirect electricity emissions are covered, with the verified embedded-emissions calculation of the exported product. The generator, industrial company, trader, EU declarant and accredited verifier each control different parts of the same evidence chain.
