Renewable electricity procurement may 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 form determines what each instrument establishes and which claims can be supported.
Physical power purchase agreements (PPAs), virtual PPAs and Guarantees of Origin (GoOs) serve distinct roles in procurement. A physical PPA sets out a contractual relationship for electricity supply. A virtual PPA typically provides financial settlement linked to a reference electricity price, while a GoO records an environmental attribute under its certification scheme.
Contract types and what they establish for CBAM claims
None of the three instruments, by itself, creates all conditions needed for installation-specific actual-emissions treatment of imported electricity under CBAM. The evidence required depends on the nature of the electricity supply being claimed. As a result, contractual documentation must align with the CBAM requirements applicable to the claim being made.
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 backed by one coherent three-party contract.
Where electricity is resold through successive bilateral transactions, this does not automatically produce the same evidentiary chain as required for qualifying physical supply. The contractual structure needs to be assessed against the applicable requirements rather than assumed to qualify based on renewable generation origin alone. This distinction affects how parties substantiate electricity-related CBAM statements.
A virtual PPA generally settles financially against a reference price rather than establishing the same physical supply relationship used for qualifying physical evidence. A GoO operates as an environmental-attribute instrument within its own certification framework. These instruments can be used together in a procurement strategy, but their individual functions need to remain distinct when supporting CBAM-related claims.
Industrial use in steel and aluminium emissions calculations
Steel and aluminium companies may use physical PPAs, virtual PPAs and GoOs to address different objectives. These objectives can include electricity procurement, price-risk management, renewable electricity disclosure and supply-chain decarbonisation. The selection of instruments is therefore tied to commercial needs that are not identical to CBAM calculation requirements.
The CBAM calculation for an imported steel or aluminium product must be assessed separately under the relevant methodology. A renewable electricity procurement arrangement or a sustainability claim cannot replace legal requirements governing embedded emissions calculations. This means that documentation supporting renewable attributes does not automatically satisfy installation-specific or methodology-specific obligations.
Contracts also need to differentiate between cooperation duties and guarantees of regulatory outcomes. Parties may warrant facts within their control, commit to deliver 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, evidence rights and contract consistency
Investors and project developers are advised to avoid double counting where environmental-attribute revenue and CBAM-linked premiums 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 expected cash flows.
Claims matrices and allocation ledgers can support tracking of which electricity volumes, environmental attributes and evidence rights are assigned to specific counterparties. Such records can also help identify conflicting commitments before they affect revenue forecasts or contractual performance. This approach is intended to align commercial documentation with the underlying allocation arrangements.
The contractual structure should ensure mutual consistency across parties, title transfers, cash flows, data rights and fallback settlement formulas. Each obligation should be assigned to a party capable of performing it. A clear separation is needed between supplying evidence and guaranteeing regulatory treatment ultimately accepted by an authority or verifier.
Commission guidance and proposed changes on electricity treatment
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 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 how electricity is treated under CBAM. The proposal includes updates to the methodology for electricity default values and parts of the conditions governing actual emissions values. It 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 being enacted legislation for current transaction assessments. For renewable electricity contracts, the commercial value of physical supply, financial price protection, environmental attributes and CBAM evidence should be identified and verified separately.
