Energy-intensive steel plants can provide renewable energy developers with long-term demand that merchant power markets may not offer. The demand is tied to industrial customers whose electricity use is linked to physical production. This can position steel mills as anchor offtakers for renewable projects even when power purchase agreements do not directly lower current CBAM certificate liabilities.
Renewable PPAs and CBAM certificate liabilities
For iron-and-steel and aluminium goods included in Annex II, the existing CBAM calculation accounts for direct emissions. Renewable electricity procurement can still generate operational, customer, financing and decarbonisation benefits without automatically reducing the certificate liability through purchased-electricity emissions. The value of a PPA therefore extends beyond the immediate effect on certificate costs.
The commercial case for a PPA is strongest when its design matches the mill’s load profile, credit quality and operational flexibility. Instead of relying on a generic green-energy label, buyers can structure arrangements around wind and solar generation combined with market shaping, hydropower or storage services. Replacement electricity costs and volumes should remain separately identifiable within the contract structure.
Linking electricity procurement with process decarbonisation
Competitive steel producers are likely to be those that pair credible electricity procurement with process decarbonisation. Addressing only one side of the equation can leave either carbon-related exposure or operating costs insufficiently managed. This interaction affects how mills approach both power sourcing and emissions reduction planning.
Long-term industrial offtake can provide renewable developers with a more predictable revenue base. Project economics depend on how the mill’s consumption profile aligns with renewable generation, along with how balancing, curtailment and replacement-power risks are allocated. These contractual details shape the financial profile of renewable projects backed by industrial demand.
Financing assessments for bankable industrial offtake
Banks financing renewable energy projects will evaluate whether the steel mill can meet payment obligations and whether contractual termination rights are acceptable. Lenders also assess curtailment allocation and any premium that depends on supporting evidence. In parallel, lenders financing the mill focus on electricity-cost competitiveness and whether a PPA reduces existing exposure or shifts risk into new contractual obligations.
The requirements differ between parties: a renewable project needs an offtake arrangement that is bankable, while the industrial buyer needs an electricity supply structure compatible with production requirements. The alignment between these needs influences whether long-term contracts can support financing and operational continuity.
CBAM’s indirect influence through carbon data and market access
CBAM strengthens decarbonisation efforts indirectly by increasing demand for carbon data from EU customers. Steel producers need credible plans for reducing emissions and demonstrating environmental performance. Renewable electricity can therefore affect customer positioning and market access even when the current certificate calculation remains focused on direct emissions.
Downstream manufacturers are expected to identify the CN codes relevant to their products and determine which sales face the greatest exposure to EU customers. This assessment can guide prioritisation of renewable electricity procurement and investments in emissions-data capabilities where commercial benefits are most likely to arise.
Planned expansion of CBAM scope from 2028
A legislative proposal would extend CBAM coverage from 2028 to selected steel- and aluminium-intensive downstream goods. Both the Council and the European Parliament support an expansion, but their proposed product lists differ and remain subject to negotiation. Until final legislation is adopted, the existing scope remains the operating baseline.
Steel buyers are therefore expected to evaluate renewable electricity against defined energy, customer or decarbonisation benefits rather than assuming a generic CBAM saving that current product methodology does not support. The anchor-offtaker model is described as strongest when project economics are independently defensible without assuming every renewable megawatt-hour reduces certificate liability.
