The Carbon Border Adjustment Mechanism is set to enter into force on January 1, with effects extending beyond carbon-intensive imports. The mechanism is formally aimed at imports including steel, cement, aluminium, fertilisers and electricity. Its impacts are beginning to intersect with the European Union’s renewable energy, battery and broader clean-technology value chains in ways not fully anticipated during the policy design phase.
Renewable energy systems are described as metal-heavy assets, with wind turbines, solar structures, grid infrastructure and battery storage systems relying on materials such as steel, aluminium and copper. Specialised alloys are also increasingly embedded across the renewable supply chain. When policies raise the cost of these base materials, the change feeds into the capital expenditure profile of renewable energy projects. For utility-scale solar and onshore wind, material-cost increases can affect project bankability where margins are already compressed by auction-based pricing and tariff assumptions.
Material-cost exposure for renewables and storage
Battery energy storage systems face additional exposure through upstream processing of key materials. The source material states that lithium, nickel, cobalt and graphite are not yet directly covered by CBAM. However, processing of these inputs relies heavily on steel, aluminium and energy-intensive industrial inputs. Battery components such as casings, racks, containers, cooling systems and power electronics are described as subject to cost inflation linked to carbon pricing on imported intermediate goods.
The timing is highlighted as a concern for European deployment plans. The source material links higher costs for battery projects to the period when policymakers rely on storage deployment to stabilise grids dominated by variable renewables. It also notes that higher CAPEX for renewables and storage can translate into higher subsidy requirements, lower investor returns or delayed project pipelines. The same text says these outcomes do not align comfortably with Europe’s decarbonisation targets.
Renewables sector pressures since 2022
The interaction is described as occurring alongside structural challenges in Europe’s renewable energy sector. After years of cost deflation, the period since 2022 is characterised by rising equipment prices, higher financing costs and growing grid-connection constraints. CBAM-related cost increases are described as risks that could reinforce these existing pressures. The source material frames this as affecting both project economics and deployment timelines.
For equipment manufacturers within Europe, the impact is presented as mixed. On paper, CBAM should protect EU-based producers of steel and aluminium inputs against imports produced under looser environmental regimes. In practice, it is described as creating a circular cost problem when imported input costs rise without domestic energy costs falling materially. Downstream manufacturers of turbines, solar mounting systems, batteries and grid equipment are then described as potentially squeezed between higher input prices and competition in global markets.
Battery manufacturing competitiveness versus Asian imports
The source material identifies battery manufacturing as a particularly acute area. It states that Europe is attempting to build a domestic manufacturing base in competition with established Asian players. European gigafactories are described as already struggling with higher electricity costs, more expensive labour and tighter environmental regulation. Additional increases in industrial input costs are said to undermine competitiveness of European battery cells, modules and systems relative to imports from Asia.
The text adds that competitiveness concerns persist even when transport costs and tariffs are factored in. It characterises CBAM as potentially weakening strategic industries it is intended to support indirectly through upstream input protection. This includes the broader clean-technology value chain where materials used for components can be influenced by carbon-related cost changes.
Implications for power markets and grid investment
The impact on electricity markets is described as adding further complexity. Renewable deployment has been linked to more frequent negative power prices in several European markets due to oversupply combined with insufficient storage and grid flexibility. At the same time, industrial power demand is described as becoming increasingly elastic, with energy-intensive industries curtailing production during high-price periods. The source material states that CBAM does not address this structural imbalance.
It further notes that raising costs for industrial producers could accelerate deindustrialisation, potentially reducing stable baseload demand. This is described as complicating the business case for both renewables and storage while destabilising power markets. Grid infrastructure and balancing assets are also identified as affected through reliance on steel and aluminium for transmission lines, substations, transformers and battery-based flexibility solutions.
Higher costs for these elements are said to translate into higher regulated asset bases for grid operators. Those higher asset bases feed into network tariffs paid by consumers and industry alike. The source material describes a feedback loop in which policies designed to decarbonise the system contribute to higher electricity costs that undermine industrial competitiveness and social acceptance of the energy transition.
Regulatory risk for investment and financing
The source material frames cumulative effects in industrial policy terms across multiple objectives pursued in parallel within Europe. These include decarbonising the economy, reshoring critical manufacturing, scaling renewables, electrifying transport and building strategic autonomy in batteries and clean technologies. It describes CBAM as interacting with these goals in ways that could create internal contradictions through increased costs across interconnected value chains.
It also links these cost effects to investment behaviour by stating they may slow investment, reduce deployment rates and deepen dependence on imported finished goods rather than strengthening domestic industrial capacity. Financing implications are also highlighted: investors in renewable energy and storage projects are described as sensitive to cost stability and regulatory predictability.
The source material points to uncertainty over CBAM implementation details including default emission values and potential future scope expansion as adding regulatory risk. It states that this risk is priced into the cost of capital, raising hurdle rates for projects already operating under tight economic constraints. Overall impacts described in the text extend beyond traditional heavy industry into renewable energy build-out and related industries.
