EU Carbon Border Adjustment Mechanism (CBAM) negotiations are being treated as a factor for renewable energy valuations ahead of any final legal changes. The Council of the EU and the European Parliament have adopted negotiating positions that relate to electricity contracting, emissions default values, and downstream coverage for selected industrial products.
The definitive CBAM regime applies from 1 January 2026. Electricity is covered under CN 2716 00 00, and the mass-based de minimis exemption introduced through the 2025 simplification does not remove electricity imports from the mechanism.
Reform proposal targets electricity rules under CBAM
The reform proposal is COM(2025) 989. It would change how electricity is handled for CBAM purposes, including the methodology for default emissions values. The proposal also addresses conditions for using actual emissions values, recognition of physical power purchase agreements (PPAs) involving intermediaries, and the congestion and nomination framework.
The Council adopted its negotiating position on 12 June 2026. The European Parliament followed on 15 September 2026. The file has moved into interinstitutional negotiations, but it remains subject to agreement and is not in force as enacted law.
Investors are expected to focus on differences between the institutions’ positions. The final provisions are described as determining how far electricity trading arrangements could change and how broadly downstream CBAM coverage might extend.
Downstream expansion from 2028 links industrial demand and electricity
The same legislative file includes a downstream expansion from 2028 for selected steel- and aluminium-intensive goods. Both institutions support broader downstream coverage, while their proposed product lists differ and remain under negotiation.
A wider downstream scope could affect demand for lower-carbon industrial inputs. At the same time, revised electricity rules could change commercial conditions for renewable electricity exports from the Western Balkans.
Renewable energy projects, electricity traders, and steel and aluminium manufacturers are therefore described as facing related investment considerations within the same policy process. The developments are presented as connected through both electricity treatment and potential downstream coverage.
Valuation approach relies on current law until adoption
The source material indicates that RES investors may incorporate these developments into valuation scenarios as potential upside. It also states that expected regulatory benefits should not be treated as established revenue before relevant legal provisions are adopted and applicable.
Project valuations can reflect possible future regulatory changes without relying on them to support base financing assumptions. Lenders are described as assessing potential upside through sensitivity analysis while keeping debt assumptions anchored in current law, existing customer demand, and demonstrable project economics.
Change-in-law provisions in contracts should specify precise triggers, including adoption, publication, and application of the relevant rules. Political agreements, committee votes, and press releases should not automatically trigger repricing, and historic imports should keep the legal basis applicable to their reporting period even after systems and contracts are updated.
Regulatory milestones to monitor during interinstitutional talks
An event-based regulatory watchlist is outlined around several milestones. These include adoption of the final regulation, official publication with dates of application, changes to implementing rules and procedures, publication or revision of applicable electricity default values, and final decisions on the downstream product list.
The source material also notes that negotiating texts and public announcements can inform scenario planning. However, they do not replace enacted legislation for compliance purposes.
For policy-sensitive renewable investments, the central principle described is maintaining flexibility for reform while keeping current-law controls until an adopted rule changes them. Regulatory probability can be used in valuation approaches, but proposed law should not be treated as an operative compliance requirement or a guaranteed source of future revenue.
