Renewable electricity producers outside the European Union must align their power purchase agreements with CBAM requirements if they want imported electricity to receive actual-emissions treatment. The contractual relationship covering the generating installation, any intermediary, and the authorised EU importing declarant is described as central to establishing electricity origin and supporting cross-border delivery evidence.
Direct physical PPAs and single tripartite agreements
A direct physical PPA between a renewable producer and an authorised EU CBAM declarant is described as a straightforward contractual setup. The agreement is expected to specify the generating installation, contracted volumes, delivery periods, pricing, the buyer, and how responsibility is allocated for obtaining records used in the EU import declaration. Separate traders or balancing service providers may support scheduling and market access if their role does not conflict with the supply relationship used for actual-emissions claims.
An alternative structure is a single tripartite PPA involving the producer, an intermediary, and the EU declarant. Commission Implementing Regulation (EU) 2025/2547 is cited as requiring that, when a PPA is concluded through an intermediary, contractual evidence must show that only one contract was concluded between all three parties. The same requirement is framed as distinguishing a qualifying tripartite arrangement from a conventional wholesale trading chain.
The text contrasts qualifying tripartite arrangements with cases where an independent power producer sells electricity to one trader under one agreement and that trader resells it to an EU importer under another. While successive transactions can be valid wholesale trades, they are described as not being classifiable as a qualifying tripartite PPA. The distinction is tied to what contractual evidence must demonstrate for CBAM purposes.
Physical delivery conditions under Regulation (EU) 2023/956
Both contractual models are stated to need to meet conditions set out in Annex IV(5) of Regulation (EU) 2023/956, which governs the EU Carbon Border Adjustment Mechanism. The generating installation must be directly linked to the EU transmission system. Alternatively, the claimant must demonstrate that there was no physical network congestion along the relevant route at the time of export.
The installation must also remain below a threshold of 550 grams of fossil-origin CO₂ per kWh. Electricity must be firmly nominated against allocated interconnection capacity by responsible transmission system operators. The nomination period and actual electricity production must match and cannot exceed one hour.
An accredited verifier is described as certifying compliance with these conditions and receiving interim evidence at least monthly. The text states that a signed PPA alone cannot establish eligibility. It adds that eligibility depends on supporting evidence covering generation, nominations, transmission arrangements, and verification.
Nominations, balancing responsibilities, and contract clarity
For direct PPAs, cross-border delivery can require additional arrangements related to operational delivery. A wind project selling to an EU trader is cited as an example where a separate entity may be needed to act as the local balancing-responsible party, manage grid deviations, and secure cross-border transmission rights. Agreements should identify who submits nominations, how imbalance charges are allocated, and what operational instructions the importing buyer can issue.
The text also describes a scenario where a trader acquires full title to electricity under a separate resale arrangement. In that case, parties are said to need reassessment of whether the direct PPA still reflects the transaction relied upon for actual-emissions treatment. It frames this as relevant to maintaining consistency between contractual structure and CBAM evidence requirements.
A tripartite agreement is described as able to accommodate an intermediary with broader contractual responsibilities. However, its provisions are said to need to distinguish the qualifying physical supply relationship from supporting commercial services. The main agreement should establish the single qualifying PPA and set out each party’s commitments.
The text further states that separate schedules can cover pricing and invoicing, dispatch instructions, cross-border capacity, balancing settlements, meter access, document retention, and transfer of data to the EU declarant. It warns that unclear contractual relationships can jeopardise anticipated treatment under actual-emissions rules.
Hourly reconciliation and allocation of emissions-related costs
The text states that annual invoices are insufficient for establishing eligible electricity quantities. Contracting parties should reconcile on an hourly basis: PPA-covered volume, metered eligible generation, accepted firm nominations, and volumes recorded in customs-import documentation. This reconciliation is presented as necessary for determining eligible quantities under CBAM actual-emissions treatment.
As an operational control, eligible quantity can be limited to the smallest hourly volume supported by available evidence if other regulatory conditions are met. The approach is described as a reconciliation safeguard rather than a replacement for statutory eligibility tests. It links eligibility determination to hourly documentation consistency across contracts and customs records.
Pricing provisions are also described as needing separation between payment for delivered electricity and any premium tied to successful emissions qualification. A producer may receive payment for all delivered megawatt-hours while receiving an additional qualification premium only for volumes supported by a satisfactory verifier’s conclusion. Contracts should specify how financial differences are handled when eligibility is lost due to inaccurate metering, late nominations, network congestion, curtailed generation, or errors attributable to the importer.
The text adds that contracts should also address whether an adverse verification result leads to repricing, indemnification, alternative delivery arrangements, or application of a default emissions factor. These elements are presented as part of how financial outcomes connect to verification results under CBAM actual-emissions treatment.
Commission proposal status and implications for contracting parties
The European Commission’s December 2025 proposal COM(2025) 989 is cited as introducing greater flexibility into aspects of the actual-emissions test. The cited areas include treatment of intermediary arrangements and physical-network conditions. As of 17 October 2026, proposed changes were stated as still subject to the EU legislative process.
The text states that contracting parties may include provisions for adapting agreements if rules change. It also notes that proposed changes should not be treated as legislation already in force. Any attempt to qualify earlier imports retrospectively is said to require awaiting enacted legal text and relevant implementation provisions.
Financing considerations for direct versus tripartite PPAs
Lenders assessing direct and tripartite PPAs are described as facing different contractual and operational considerations. A direct agreement is characterised as generally providing a more straightforward legal chain for tracing electricity origin. Additional arrangements may still be required for balancing, scheduling, and cross-border services.
A tripartite structure is described as allowing importing buyers to benefit from a trading intermediary’s infrastructure while combining contractual, operational, and evidentiary responsibilities into a multi-party instrument. For both structures, the test described in the text focuses on whether each claimed electricity import can be traced from the generating installation through contractual and physical delivery arrangements to the EU import declaration.
The same tracing requirement is linked to availability of required evidence for independent verification. The text frames this as applicable across both direct PPAs and single tripartite agreements when seeking CBAM actual-emissions treatment for imported renewable electricity.
