Renewable electricity procurement can combine physical power delivery, financial price hedging and environmental attributes, but these arrangements do not provide interchangeable benefits under the EU Carbon Border Adjustment Mechanism (CBAM). For electricity producers, traders and industrial buyers, the contractual distinction between physical power purchase agreements (PPAs), virtual PPAs and Guarantees of Origin (GoOs) determines what each instrument establishes and which claims it can support.
A physical PPA establishes a contractual relationship for electricity supply. A virtual PPA generally provides financial settlement against a reference electricity price, while a GoO records an environmental attribute under the applicable certification scheme. None of these instruments, on its own, establishes every condition required for installation-specific actual-emissions treatment of imported electricity under CBAM.
Physical electricity supply and CBAM evidence
Commission Implementing Regulation (EU) 2025/2547 specifies the contractual evidence requirements for qualifying physical electricity supplies. A physical PPA can be concluded directly between the electricity producer and the relevant authorised CBAM declarant. Where an intermediary is involved, the relevant physical supply must be supported by one coherent three-party contract.
Successive bilateral resales do not, by themselves, establish the same evidentiary chain. The contractual structure must therefore be assessed against the applicable requirements rather than assumed to qualify solely because the electricity originates from renewable generation.
A virtual PPA serves a different commercial purpose because it generally settles financially against a reference price rather than establishing the same physical supply relationship. A Guarantee of Origin serves an environmental-attribute function under its scheme. These instruments can coexist within a procurement strategy, but their individual roles must remain clear when substantiating electricity-related CBAM claims.
Industrial procurement and emissions accounting
Steel and aluminium companies may use physical PPAs, virtual PPAs and GoOs to address different commercial objectives, including electricity procurement, price-risk management, renewable electricity disclosure and supply-chain decarbonisation.
However, the CBAM calculation applicable to an imported steel or aluminium product must be assessed separately under the relevant methodology. A renewable electricity procurement arrangement or sustainability claim cannot substitute for the legal requirements governing the calculation of embedded emissions.
Contracts should also distinguish between obligations to cooperate and guarantees of a regulatory outcome. Parties can warrant facts within their control, undertake to deliver specified records and allocate financial consequences for contractual failures. They cannot use those provisions to transfer the statutory responsibilities of the entity legally obligated under CBAM.
Revenue attribution and contractual verification
Investors and project developers need to avoid double counting environmental-attribute revenue and CBAM-linked premiums where both depend on the same generation output or an exclusivity commitment. Revenue due diligence should identify the claims associated with each product and reconcile them against contractual allocation records.
Claims matrices and allocation ledgers can help establish which electricity volumes, environmental attributes and evidence rights have been assigned to particular counterparties. These records also help identify conflicting commitments before they affect revenue forecasts or contractual performance.
The contractual structure should make the parties, title transfers, cash flows, data rights and fallback settlement formula mutually consistent. Each obligation should be assigned to a party capable of performing it, with a clear distinction between supplying evidence and guaranteeing the regulatory treatment ultimately accepted by an authority or verifier.
EU guidance and proposed electricity reforms
The European Commission published definitive-period sector guidance on 14 August 2026, including dedicated guidance for electricity, iron and steel, and aluminium. It 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, including the methodology for electricity default values and parts of the conditions governing actual emissions values. It would 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 and must not be treated as 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 therefore be identified and verified separately.
