The European Commission has put forward changes to the EU’s Carbon Border Adjustment Mechanism (CBAM) electricity rules that would allow power purchase agreements involving intermediaries to qualify for actual-emissions treatment. The proposal, dated Brussels, October 27, 2026, addresses a constraint in the current framework. Under the existing approach, a qualifying PPA must be concluded directly between an authorised CBAM declarant and a third-country electricity producer.
Direct PPA requirement meets intermediary-based market structures
Electricity trading arrangements often include traders, aggregators and licensed suppliers between generators and final buyers. These intermediaries provide market access, balancing services, collateral arrangements and cross-border scheduling. In some cases, that structure makes direct contracting between independent power producers and EU importers commercially difficult.
The Commission proposal is designed to recognise intermediary-based contractual structures within the CBAM electricity framework. It would seek to accommodate physical PPA chains where the contractual relationships and the connection to the source installation can be shown. The change is still at the legislative proposal stage rather than an adopted rule.
For imports under the framework applicable to 2026, the qualifying PPA requirement would continue to require a direct agreement between the authorised CBAM declarant and the producer. The Commission’s December 2025 proposal would broaden the framework to accommodate intermediaries, subject to final terms agreed by the Council and the European Parliament.
Compliance documentation and verification remain central
The financial implications described in the proposal extend beyond the electricity purchase price. Trading margins can be narrow, and transactions that appear attractive based on energy costs and cross-border price spreads may become less profitable if actual-emissions treatment cannot be substantiated. In that case, a higher default emissions factor would apply.
Commercial assessments are therefore expected to model both a qualifying case and a fallback scenario. The approach is described as particularly relevant for long-term PPAs whose pricing arrangements extend across multiple regulatory years. The proposal also indicates that allowing intermediaries would not remove documentation requirements.
Instead, it would place greater emphasis on demonstrating the integrity of the contractual and physical chain. Agreements would need to establish relationships between the generating installation, intermediary and authorised declarant. They would also need to prevent double allocation of generation and preserve access to hourly production and scheduling data.
Verification under an intermediary-compatible structure would require a controlled allocation methodology. The methodology would trace relevant electricity through the contractual chain rather than relying solely on a bilateral PPA. This is presented as a shift in how tracing evidence would be handled for CBAM electricity claims.
Evidence responsibilities distributed across participants
Records needed for a CBAM electricity claim are described as being distributed among multiple participants. The generating plant holds production data, while traders may control nominations. Transmission system operators retain relevant capacity or flow records, and the EU importer remains responsible for its CBAM declaration.
Contracts are expected to specify who retains each record, how long it must be kept and how quickly it must be made available to the verifier. Without enforceable access to evidence, electricity may fail to qualify for intended treatment even if physical origin and generation can otherwise be traced.
If adopted, the reform could support supply models where utilities and aggregators combine renewable generation from several third-country installations. Those combined volumes could then be delivered to EU importers through a single trading platform. The proposal also notes that such arrangements could raise additional questions about allocating emissions performance, failed operating hours and verification expenses among participating parties.
Western Balkans relevance for regional trading structures
The proposed flexibility is described as particularly relevant in the Western Balkans. Independent producers in that region often sell electricity through regional trading companies rather than maintaining direct access to EU import markets.
In Serbia and Montenegro, aggregators could potentially combine generation, market access and CBAM documentation while preserving the required connection to the source installation. The commercial benefit would depend on final legal requirements and on whether each participant can provide evidence needed for verification.
For independent power producers, aggregators, suppliers, traders, corporate buyers and EU importers, the immediate priority is distinguishing any intermediary-compatible framework from requirements governing 2026 imports. Scenario planning and contract negotiations can draw on positions taken by the Council and European Parliament alongside the Commission proposal.
Planning around current rules and potential amendments
A two-scenario approach is described as a way for companies to prepare without relying prematurely on legislative change. One scenario reflects the direct-PPA requirement applicable to 2026 imports. The other scenario assesses potential effects of an intermediary-compatible framework.
The proposal states that existing transactions for 2026 must comply with rules in force. New long-term agreements could include conditional clauses allowing intermediary arrangements if an amendment is adopted. This is intended to avoid treating proposed flexibility as an automatic compliance option before amending legislation enters into force.
Implementation is also described as requiring links between compliance documentation and purchasing, production, customs and financial records. Using shared underlying information for verification and commercial management is presented as a way to assess how changes in suppliers, trading routes, prices or legal requirements affect outcomes.
Building a compliance file before reporting periods
Before finalising a transaction or reporting period, companies should connect contract details with generating installation information, meter data, electricity schedules and cross-border records. Documentation should identify who approves each assumption. It should also establish a fallback where preferred emissions treatment cannot be demonstrated.
The fallback may be less commercially attractive but defining it in advance helps assess exposure if challenged by a verifier, customs authority or authorised declarant. It also supports management of price adjustments, changes in verification requirements and internal reporting processes.
The proposal notes that as CBAM’s financial impact increases over coming years, preventable evidence gaps could become recurring costs for electricity suppliers and importers. A documented process is described as helping distinguish genuine emissions performance from claims that cannot be adequately substantiated under verification requirements.
Until any amendment is adopted, the existing direct-PPA requirement remains described as the applicable legal test for qualifying CBAM electricity under 2026 imports.
