Cross-border electricity transactions can involve several companies performing different commercial, operational and customs functions. The electricity seller, final buyer, transmission-capacity holder, scheduling agent and customs importer may all be separate legal entities, making the identification of the responsible EU Carbon Border Adjustment Mechanism (CBAM) declarant a central compliance issue.
Under Regulation (EU) 2023/956, the relevant obligations include reporting imported electricity, declaring its embedded emissions and surrendering the required CBAM certificates. The first annual CBAM declaration covering 2026 imports is due on 30 September 2027. Contractual arrangements may allocate the economic cost of compliance between commercial parties, but they do not automatically transfer statutory responsibilities away from the legally responsible declarant.
Electricity imports and the declarant designation
Electricity has specific provisions because cross-border flows are linked to allocated interconnector capacity. Article 5(4) of Regulation (EU) 2023/956 addresses persons to whom transmission capacity for electricity is allocated through explicit capacity allocation and who nominate that capacity for import.
Trading companies must therefore examine the actual border transaction and applicable customs arrangements when identifying the responsible party. Naming an EU offtaker in a power purchase agreement (PPA) does not, by itself, resolve every question concerning the legally responsible declarant. The electricity-specific provisions must also be considered when determining which participant bears the relevant obligations.
Six checks for mapping contractual and operational responsibilities
A cross-border electricity transaction should be mapped against six questions:
- Which legal entity owns the electricity immediately before and after the relevant border transaction?
- Which entity holds the explicit transmission-capacity right, where applicable?
- Which entity submitted the final accepted nomination?
- Which company performs the customs import formalities?
- Which entity will submit the CBAM declaration?
- Which party holds the original generating-plant and network evidence?
Different answers do not necessarily indicate a compliance failure. However, discrepancies must be explainable through the contractual arrangements, transaction records and supporting documentation.
Corporate structures can complicate actual-emissions claims
Consider a Serbian wind farm selling electricity to a regional trading company that uses a Hungarian affiliate for market access. The affiliate may hold the capacity allocation and manage the imported electricity position, while its parent company records the economic exposure.
If the affiliate is the legally responsible declarant, a physical PPA naming only the parent company may fail to establish the required contractual link between the generating producer and the declarant for actual-emissions treatment. Membership of the same corporate group does not, by itself, replace the need for a qualifying contractual arrangement.
The relevant parties must therefore establish which entity occupies the import position and ensure that the PPA and supporting evidence correspond to the applicable CBAM requirements.
Responsibility matrices and evidence management
A practical control is to agree on a responsibility matrix alongside the electricity supply contract. It should identify the entity accountable for each relevant function, including the physical PPA, interconnection capacity, hourly nominations, metering evidence, verification instructions, registry data and CBAM certificate surrender.
Data-processing providers can manage documentation workflows, while engineering advisers can assemble emissions evidence and technical records. Their involvement does not automatically make them the authorised CBAM declarant or transfer the statutory obligation to them.
Clear allocations of responsibility also help identify gaps between the company managing the physical delivery, the entity controlling the supporting evidence and the party submitting the declaration.
Statutory liability and contractual reimbursement
Legal responsibility for CBAM must be distinguished from the commercial allocation of resulting costs. A generator may warrant the accuracy of installation data and indemnify an importing trader for losses arising from incorrect information. A scheduling agent may accept liability for missed nominations under its service agreement.
Where the contracts provide for reimbursement, the importer may be able to recover specified losses from the responsible counterparty. Such provisions do not, however, transfer the importer’s public-law CBAM obligations to the generator, scheduling agent or engineering adviser.
Electricity companies establishing new trading routes into the EU therefore need to identify the legally responsible declarant before agreeing on the carbon premium. The contractual value of a PPA depends in part on whether the named parties can establish the qualifying relationship, control the relevant import position and produce the evidence required to support the electricity’s claimed emissions treatment.
