Proposed changes to the European Union’s Carbon Border Adjustment Mechanism (CBAM) could widen the routes available to renewable electricity exporters seeking recognition of actual emissions. The reforms could make multi-trader transactions easier to structure and reduce some evidence requirements, but electricity producers and importers still face uncertainty over when the changes will take effect and which conditions will ultimately apply.
As of October 2026, the definitive CBAM regime has been operating since January, while the proposed electricity-related amendments remain subject to the legislative process. Businesses must therefore distinguish between requirements currently in force and potential future benefits.
Commission proposal targets electricity methodology and trading structures
The European Commission’s COM(2025) 989, presented in December 2025, combines measures addressing downstream CBAM goods and anti-circumvention with proposed changes to the electricity methodology.
For electricity, the proposal would broaden access to actual-emissions treatment, including changes to the rules governing contractual intermediaries and the physical-network congestion requirement. It would also revise the default emissions methodology to reflect a broader electricity generation mix, rather than relying on fossil-fuel generation in the same way as the existing approach described in the proposal.
These measures remain proposals. They do not currently provide electricity exporters with automatic eligibility for more favourable treatment.
A broader default factor could change export economics
The proposed methodology could have material implications for neighbouring countries with significant hydropower, wind and solar generation. A default factor based on fossil-fuel generation may produce a relatively high emissions value compared with a country’s overall electricity output mix.
A methodology reflecting a broader generation mix could narrow that difference and alter the carbon-cost assumptions used by electricity importers. It could also affect the relative commercial positions of independent power producers (IPPs), traders and projects seeking installation-specific power purchase agreements.
The actual impact would depend on the final legislative wording and the official emissions factors adopted under the applicable rules. A country’s renewable share alone would not establish the precise reduction in its default emissions treatment.
Proposed intermediary changes could reopen multi-trader routes
The existing implementing framework recognises a direct power purchase agreement (PPA) and a limited tripartite contractual structure. The Commission’s proposed changes could allow a wider range of verifiable contractual chains to support actual-emissions claims, potentially accommodating more conventional electricity trading arrangements.
Such flexibility could reduce the need to restructure transactions around a single three-party contract whenever multiple intermediaries participate in a sale.
However, broader contractual recognition would not eliminate the requirement to substantiate the electricity volumes claimed. The EU importer would still need evidence showing that the electricity was generated, nominated and imported in accordance with the final applicable regulation. Reliable allocation controls would remain essential to prevent unsupported or duplicated claims.
Congestion evidence remains a compliance issue
The physical-network congestion condition is another focus of the proposed reform. Market participants can face difficulties obtaining evidence covering the relevant transmission route for individual import hours, creating an additional documentation burden for renewable generators and EU buyers.
The Commission has proposed removing this condition as part of the reform package. If adopted and made applicable, the change could reduce the evidence burden associated with demonstrating qualifying electricity imports.
Until the amendment enters into force and applies to the relevant transactions, however, exporters cannot assume that the current congestion-evidence requirements have been waived.
Proposed 2026 application creates a recordkeeping challenge
The Commission’s proposal envisages applying certain electricity-methodology changes to imports from 1 January 2026, allowing the revised rules to be used for the first annual declarations due in September 2027 if the relevant provisions are ultimately adopted in that form.
Such an approach would have retrospective effect for the covered imports. Businesses should therefore retain their 2026 records even if they anticipate a future simplification. The final legislation may differ from the draft or establish specific conditions for recalculating historical imports and declarations.
The legislative timetable remains another source of uncertainty. The European Parliament adopted amendments at first reading on 15 September 2026, after which the file proceeded to interinstitutional negotiations. As of 17 October 2026, the final text and implementation timetable remained uncertain.
Contracts should reflect this distinction between the rules currently applicable and the anticipated changes. Pricing, evidence obligations and qualification claims should not depend on proposed provisions as though they were already enforceable.
PPAs need mechanisms for future rule changes
Electricity offtake agreements can address the uncertainty through conditional provisions that take effect only when specified legal changes become applicable. For example, a PPA could allow the eligible volume pool to expand or permit additional contractual intermediaries once the relevant requirements are satisfied.
Contracts should also address the treatment of historical 2026 transactions, including whether previous settlements can be reopened, whether corrected information must be submitted by the buyer, and how any realised carbon-cost savings would be allocated between the parties.
Without clear provisions, a reform intended to facilitate electricity trade could create disputes over the financial value of earlier imports and the responsibilities of individual participants in the contractual chain.
For regional electricity markets, the proposed changes offer a potential route to broader access and more flexible trading structures, but their commercial value remains uncertain until enforceable rules are established. Exporters, traders and importers need to preserve current evidence, negotiate contracts capable of accommodating legal changes and avoid pricing anticipated regulatory benefits before the necessary amendments take effect.
