Renewable electricity procurement arrangements can combine physical power delivery, financial price hedging and environmental attributes. Under the EU Carbon Border Adjustment Mechanism (CBAM), these elements do not create interchangeable compliance outcomes. For electricity producers, traders and industrial buyers, the contractual distinction between physical power purchase agreements (PPAs), virtual PPAs and Guarantees of Origin (GoOs) affects what each instrument establishes and which claims it can support.
A physical PPA sets out a contractual relationship for electricity supply. A virtual PPA generally provides financial settlement against a reference electricity price. A GoO records an environmental attribute under the applicable certification scheme. None of these instruments, by itself, establishes every condition needed for installation-specific actual-emissions treatment of imported electricity under CBAM.
Contractual evidence for qualifying physical electricity
Commission Implementing Regulation (EU) 2025/2547 sets out contractual evidence requirements for qualifying physical electricity supplies. A physical PPA may be concluded directly between the electricity producer and the relevant authorised CBAM declarant. Where an intermediary is involved, the physical supply must be supported by one coherent three-party contract.
The evidentiary chain cannot be assumed to qualify based solely on renewable generation origin. Successive bilateral resales do not, by themselves, establish the same contractual evidence structure. The contractual setup therefore needs assessment against the applicable requirements rather than relying on origin alone.
Virtual PPAs operate under a different commercial mechanism because they typically settle financially against a reference price. This generally does not create the same physical supply relationship as a physical PPA for CBAM evidence purposes. GoOs function as environmental-attribute records within their certification scheme. These instruments can be used together in one procurement strategy, but their roles must remain distinct when substantiating CBAM-related electricity claims.
Use of PPAs and GoOs in steel and aluminium reporting
Steel and aluminium companies may use physical PPAs, virtual PPAs and GoOs to meet different commercial objectives. These objectives can include electricity procurement, price-risk management, renewable electricity disclosure and supply-chain decarbonisation. The instruments therefore may appear in the same broader procurement approach.
CBAM calculations for an imported steel or aluminium product must still be assessed separately under the relevant methodology. A renewable electricity procurement arrangement or a sustainability claim cannot replace legal requirements governing embedded emissions calculations. The CBAM treatment applicable to the imported product is therefore not substituted by contract-based renewable disclosures.
Contracts also need to separate obligations to cooperate from guarantees of regulatory outcomes. Parties can warrant facts within their control, commit to delivering specified records and allocate financial consequences for contractual failures. However, such provisions cannot transfer statutory responsibilities of the entity legally obligated under CBAM.
Revenue allocation and verification across contract layers
Investors and project developers are advised to avoid double counting environmental-attribute revenue and CBAM-linked premiums when both depend on the same generation output or an exclusivity commitment. Revenue due diligence should identify which claims relate to each product and reconcile them with contractual allocation records. This includes checking how commitments map to specific revenue streams.
Claims matrices and allocation ledgers can support tracking of assigned electricity volumes, environmental attributes and evidence rights across counterparties. These records can also help detect conflicting commitments before they affect revenue forecasts or contractual performance. The purpose is to ensure that assigned rights align with what each counterparty is expected to deliver.
The contractual design should keep parties, title transfers, cash flows, data rights and fallback settlement formulas mutually consistent. Each obligation should be assigned to a party capable of performing it. A clear distinction is needed between supplying evidence and guaranteeing regulatory treatment ultimately accepted by an authority or verifier.
European Commission guidance and proposed changes
The European Commission published definitive-period sector guidance on 14 August 2026, including dedicated guidance for electricity, iron and steel, and aluminium. It also updated its general CBAM questions and answers on 15 October 2026. These materials support implementation but do not replace binding regulations and implementing acts.
A separate reform proposal, COM(2025) 989, would change electricity treatment under CBAM. It includes modifications to the methodology for electricity default values and parts of the conditions governing actual emissions values. The proposal would also broaden the concept of physical PPAs involving intermediaries and modify the congestion and nomination framework.
The Council adopted its negotiating position on 12 June 2026, followed by the European Parliament’s position on 15 September 2026. The proposal remains under interinstitutional negotiation rather than enacted legislation when assessing current transactions. For renewable electricity contracts, the commercial value of physical supply, financial price protection, environmental attributes and CBAM evidence should be identified and verified separately.
