Electricity exports from the Western Balkans to the European Union are increasingly dependent on whether importers can demonstrate the origin, emissions profile and contractual traceability of delivered power. For independent power producers (IPPs), trading companies and EU importers, the ability to substantiate actual embedded emissions is becoming a key factor in cross-border electricity transactions.
CBAM obligations for imported electricity
The EU’s Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase on 1 January 2026, covering imported electricity under customs code 2716 00 00. Unlike certain industrial goods that benefit from a 50-tonne annual threshold, electricity imports have no equivalent mass-based exemption. The EU entity responsible for an electricity import must therefore determine its applicable CBAM declaration and certificate obligations regardless of the volume or delivery profile.
A key distinction exists between electricity assessed using the applicable country default emissions factor and electricity for which the authorised EU CBAM declarant can demonstrate actual embedded emissions. The latter approach can be relevant to wind, solar and hydropower producers, but eligibility depends on meeting the applicable requirements.
Under the rules described as applicable in October 2026, the process involves a qualifying power purchase agreement (PPA), transmission-system evidence, emissions eligibility, firm hourly nominations and independent verification. Renewable energy certificates, trader invoices or general declarations that electricity comes from a green installation cannot independently replace these requirements.
Cross-border trading flows and price differences
The Energy Community Secretariat reported that commercially scheduled electricity trade across EU–Western Balkan borders declined by 25% in the first quarter of 2026. During the same period, average day-ahead electricity prices in the Western Balkans were approximately €30/MWh below prices in neighbouring EU markets.
The price differential indicated that conventional arbitrage opportunities had become more difficult to monetise, even when electricity was available at lower prices in the Western Balkans. A report covering the second quarter recorded a partial recovery in cross-border flows, while renewable generators continued to face difficulties documenting actual emissions.
Producers reconsider export and offtake arrangements
Independent power producers must assess whether to sell electricity into local wholesale markets, conclude domestic industrial PPAs or allocate part of their output to a specifically identified EU importer under a more detailed contractual arrangement.
Electricity sold through several successive traders may still be traded and delivered operationally, but a conventional chain of resales does not necessarily meet the requirements for recognition of actual emissions. A direct PPA between the producer and the authorised EU CBAM declarant provides a clearer contractual starting point. A carefully structured tripartite agreement involving an intermediary is another possible arrangement.
For trading houses, the challenge concerns the relationship between their commercial activities and their contractual responsibilities. Their established functions include aggregating purchases, managing congestion rights, optimising positions across exchanges and selling flexible delivery products. CBAM does not remove those functions, but traders must distinguish whether they act as a commercial principal, a nominated intermediary or a provider of scheduling and balancing services.
These roles must correspond to the parties’ actual legal obligations rather than relying solely on the terminology used in contract documents.
Carbon certificate prices and import economics
The financial implications are linked to the price of CBAM certificates. The official certificate price for the third quarter of 2026 was €82.32 per tonne of CO₂e, up from €75.28/tCO₂e in the second quarter.
At a hypothetical default exposure of one tonne of CO₂e per MWh, the gross carbon cost would exceed €82/MWh before any applicable statutory adjustment. Under that assumption, an ordinary transmission-cost or wholesale-price differential would not be sufficient to sustain an import margin.
This calculation is illustrative rather than a universal charge on imported electricity. The actual liability depends on the legally applicable emissions value and other relevant regulatory provisions.
CBAM eligibility becomes a financing consideration
Lenders evaluating renewable energy projects designed around electricity exports to the EU need to assess more than signed offtake agreements and projected baseload or capture prices. They must also consider which delivery volumes can qualify for actual-emissions treatment and how much generation could instead be subject to default emissions values.
Other relevant factors include the allocation of costs when eligibility is lost, the project’s resilience to interruptions in cross-border transmission capacity and the consequences of an adverse verification finding. A long-term PPA may provide weaker financial security if the expected premium for renewable electricity cannot be substantiated under the applicable CBAM requirements.
Contract provisions for traceability and compliance
Electricity export contracts need to distinguish between the physical energy price, balancing and transit charges, data-delivery obligations, carbon-cost adjustments and remedies for failures in the supporting evidence.
Responsibilities should be allocated according to the parties’ functions. The generating installation operator would be responsible for metering records, the relevant market participant for nominations, and the authorised EU CBAM declarant for the final CBAM declarations.
Contracts should also address changes in legislation. EU institutions are discussing more flexible rules for electricity imports, but the measures described in the source remain under debate and have not yet been enacted. Any contractual mechanism addressing such changes must therefore distinguish existing legal obligations from potential future amendments.
For producers and traders operating between the Western Balkans and the EU, the commercial challenge is to connect renewable generation with deliverable electricity volumes, legally traceable transactions and independently verified emissions data. The ability to establish that connection is becoming an important consideration in securing and maintaining access to EU electricity markets.
