The European Commission has put forward proposed 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 limitation 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.
Intermediary structures in electricity contracting
Electricity trading arrangements often include traders, aggregators and licensed suppliers between generators and final buyers. These intermediaries can provide market access, balancing services, collateral arrangements and cross-border scheduling. In some cases, this structure makes direct contracting between independent power producers and EU importers commercially difficult.
The Commission’s proposal would recognise intermediary-based contractual setups to expand the number of independent generators able to supply electricity under qualifying arrangements. It would seek to accommodate physical PPA chains where the contractual relationships and the connection to the source installation can be demonstrated.
The change is still a legislative proposal rather than an adopted rule. For imports covered by the 2026 framework, the qualifying PPA requirement remains direct contracting 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 European Parliament.
Compliance and documentation requirements
Commercial implications 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.
Companies are expected to assess both the qualifying case and a fallback scenario, including which party would bear any resulting cost difference. This is particularly relevant for long-term PPAs with pricing arrangements spanning multiple regulatory years.
Even if intermediaries are allowed, documentation requirements would not be removed. The emphasis would shift toward demonstrating integrity across the contractual and physical chain. Agreements would need to define the relationship between the generating installation, intermediary and authorised declarant, prevent double allocation of generation, and preserve access to hourly production and scheduling data.
Verification would also require a controlled allocation methodology able to trace relevant electricity through the contractual chain. The approach would not rely solely on a bilateral PPA.
Evidence handling across generators, traders and importers
Records needed for a CBAM electricity claim are held by multiple participants in the supply chain. The generating plant holds production data, traders may control nominations, transmission system operators retain capacity or flow records, and the EU importer remains responsible for its CBAM declaration.
Contracts should specify who retains each record, how long it must be kept and how quickly it must be provided to a verifier. Without enforceable access to evidence, electricity may fail to qualify even when physical origin and generation can otherwise be traced.
If adopted, the reform could support a supply model where utilities and aggregators combine renewable generation from several third-country installations for delivery to EU importers through a single trading platform. Such structures could reduce transaction costs while raising additional questions about allocation of emissions performance, failed operating hours and verification expenses among participating parties.
Relevance for Serbia and Montenegro
The proposed flexibility could be particularly relevant in the Western Balkans, where independent producers often sell electricity via regional trading companies rather than maintaining direct access to EU import markets. This context is linked to intermediary involvement in sales arrangements rather than direct contracting with EU counterparties.
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, an immediate priority is distinguishing any proposed intermediary-compatible framework from requirements governing 2026 imports. The Commission proposal and positions taken by the Council and European Parliament can inform scenario planning and contract negotiations.
Planning contracts under current 2026 rules
A two-scenario model is described as a way for companies to prepare without relying on legislative change before it is adopted. One scenario reflects the direct-PPA requirement applicable to 2026 imports; another assesses potential effects under an intermediary-compatible framework.
Existing 2026 transactions must comply with rules in force. New long-term agreements can include conditional clauses intended to permit intermediary arrangements if an amendment is adopted. This avoids assuming that proposed flexibility already creates a legal entitlement.
Implementation should connect compliance documentation with purchasing records, production data, customs records and financial records. Using shared underlying information for verification and commercial management is intended to make it easier to evaluate how changes in suppliers, trading routes, prices or legal requirements affect outcomes.
Building a compliance file before reporting
Before finalising a transaction or reporting period, companies should be able to link contract terms with generating installation details, meter data, electricity schedules and cross-border records. Documentation should also identify who approves each assumption. A fallback should be established in cases where preferred emissions treatment cannot be demonstrated.
Defining fallback conditions in advance helps assess exposure before challenges by a verifier, customs authority or authorised declarant. It also supports management of price adjustments as verification requirements change alongside internal reporting needs.
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 a way to distinguish genuine emissions performance from claims that cannot be adequately substantiated.
