Power traders supplying aluminium producers are increasingly expected to provide more than electricity. Some industrial customers seek a single commercial arrangement covering physical power, renewable energy attributes, and evidence for specific regulatory or customer claims. Each component is expected to retain a defined purpose and value within that arrangement.
Contract structures separating electricity, GoOs, and supporting services
Bundled supply arrangements can reduce procurement complexity for aluminium smelters and fabricators. Contracts are still expected to distinguish the price paid for electricity from the cost of Guarantees of Origin (GoOs). They should also separate any services covering metering, data management, or verification support.
This separation is intended to prevent one contractual instrument from being used to substantiate a claim it cannot independently prove. Renewable attribute contracts are also expected to prevent the same environmental claim from being sold more than once. This is particularly relevant when a generating project serves multiple industrial buyers.
Power and GoO records can be reconciled to show the allocation of electricity and its associated attributes. However, owning a renewable attribute alone does not establish compliance with a specific CBAM electricity route. The allocation of records is therefore treated as necessary but not sufficient for route-specific compliance.
Renewable electricity procurement and current CBAM liability
For iron-and-steel and aluminium goods listed in Annex II, the existing CBAM calculation takes account of direct emissions. Renewable electricity procurement can provide operating, customer, financing, and decarbonisation value without automatically reducing current CBAM certificate liability through purchased-electricity emissions.
For an aluminium smelter or fabricator, an electricity contract can support operating-cost competitiveness and decarbonisation. At the same time, the product’s CBAM calculation follows its applicable methodology. This distinction is described as important when a trader supplies multiple production sites or separate legal entities within the same corporate group.
The legislative file also proposes a downstream expansion from 2028 for selected steel- and aluminium-intensive goods. The Council of the EU and the European Parliament support extending coverage, but their proposed product lists differ and remain under negotiation. Until final legislation is adopted, the existing scope is treated as the operating baseline.
Evidence services, allocation controls, and customer claim documentation
Traders offering repeatable evidence services may secure more durable margins than competitors relying only on commodity electricity prices. Such offerings can combine energy procurement, attribute allocation, and organised data supporting customer or regulatory requirements.
Lenders and investors are expected to require clear liability caps and controls against double allocation. Contractual responsibilities should specify which party supplies underlying data, maintains allocation records, and supports each agreed claim.
Customer contracts for low-carbon aluminium are expected to specify the precise commitment being purchased. A product-carbon-footprint claim, a renewable-electricity sourcing commitment, a maximum emissions threshold, and a disclosure requirement each require different supporting evidence. Different elements may also justify different commercial premiums.
COM(2025) 989 electricity reform negotiations
A separate reform proposal, COM(2025) 989, would materially change electricity treatment under CBAM. The proposal includes changes to the methodology for electricity default values and aspects of the conditions for using actual values.
The reform would also allow a broader concept of physical power purchase agreements involving intermediaries. It would change the congestion and nomination framework used in relation to electricity arrangements.
The Council adopted its negotiating position on 12 June 2026, while the European Parliament adopted its position on 15 September 2026. The proposal remains under interinstitutional negotiation and is not treated as enacted law.
The future supplier to power-intensive aluminium producers is described as likely combining energy-market services with environmental-attribute management and structured data support. For buyers, the key decision described is separating electricity-cost competitiveness from process-carbon compliance while assessing each transition measure by demonstrable benefit.
