India Aluminium Wire Rod Imports Face CVD Sunset Review on Malaysian Supply

India's Trade

India aluminium wire rod imports from Malaysia are under renewed trade scrutiny after the Directorate General of Trade Remedies started a sunset review of existing countervailing duties. The review comes ahead of the current duty’s expiry on 23 September.

India aluminium wire rod imports are strategically important because wire rod is a key semi-finished aluminium product for electrical conductors, cables, industrial wire and downstream manufacturing. Domestic producers argue that subsidised Malaysian supply could continue or recur if the duty expires.

India aluminium wire rod imports from Malaysia have been subject to countervailing duties since September 2021. The original levy followed a probe launched in June 2020 into alleged government subsidies supporting Malaysian producers.

Hindalco Industries, Vedanta and Bharat Aluminium Company filed the application that triggered the review. DGTR said the applicants represent a majority of India’s domestic output of the product covered by the duty.

Domestic Producers Warn of Subsidy and Trade Diversion Risk

The review covers aluminium wire and rod in coil form with diameters of 9-13mm. These products are used across electrical, cable and industrial supply chains, making them important to India’s aluminium downstream sector.

The applicants argue that Malaysian producers continue to benefit from government support. They identified 64 subsidy programmes, including 23 from the original investigation and 41 new schemes.

The alleged support includes tax breaks, export grants, preferential financing and below-market land and power rates. If confirmed, these measures could allow Malaysian producers to offer aluminium wire rod at artificially competitive levels.

Indian producers warned that removing the duty could harm the domestic industry. Their concern is that subsidised imports would pressure local pricing, reduce utilisation and weaken investment confidence in downstream aluminium capacity.

The case also includes a wider trade-flow risk. Recent increases in US Section 232 aluminium tariffs could divert Malaysian export volumes away from the US and toward India if the CVD lapses.

This matters because aluminium trade measures in one region can quickly reshape flows elsewhere. When one market becomes harder to access, exporters often look for alternative destinations with weaker trade barriers.

Review Could Shape India’s Downstream Aluminium Protection

The period of investigation for the sunset review is July 2024-December 2025. DGTR will assess whether the duty should be extended, modified or withdrawn.

Exporters, importers, users and the Malaysian government have been invited to submit comments through DGTR’s SETU portal. Their responses will help determine whether subsidised imports remain a material risk.

The outcome will matter for India’s aluminium value chain. Domestic producers want protection from subsidised competition, while downstream users may focus on supply availability and input cost.

India has been trying to strengthen local manufacturing across metals, electrical infrastructure and industrial materials. Maintaining fair competition in aluminium wire rod supports that policy direction, especially as demand grows from power transmission, cables, construction and manufacturing.

However, trade protection also needs balance. If duties raise input costs too much, downstream processors can become less competitive. The review will need to weigh domestic producer protection against the needs of users that rely on wire rod supply.

The case shows how aluminium is becoming more exposed to trade policy. Tariffs, subsidies, countervailing duties and regional trade diversion are now central to market positioning, not secondary issues.

The Metalnomist Commentary

India’s CVD review shows that aluminium downstream products are becoming part of a wider trade-defence strategy. The key issue is whether India can protect domestic wire rod capacity without raising costs for cable, conductor and electrical manufacturing supply chains.

Germany Data Centre Capacity Strategy Targets Major AI and Grid Expansion by 2030

Data Center

Germany data centre capacity is set for a major expansion after the cabinet adopted a national strategy targeting at least a two-fold increase by 2030. The plan also aims to quadruple Germany’s AI and high-performance computing capacity over the same period.

The strategy reflects Germany’s push to strengthen digital sovereignty while competing for AI infrastructure investment. It also places data centres directly inside the country’s energy, grid, and industrial planning agenda.

Germany data centre capacity stood at 2.98GW in 2025, more than double the level recorded in 2010. AI and high-performance computing capacity totalled 500MW, while total data centre power consumption reached 21TWh.

Grid Connections Become the Main Bottleneck for AI Infrastructure

Germany’s data centre strategy identifies grid access as one of the biggest constraints on future growth. The country has strong supply security and a renewables-rich power mix, but long connection queues and limited grid capacity could slow new projects.

The strategy calls for data centre demand to be included earlier in grid infrastructure planning. It also supports more flexible connection rules, allowing transmission system operators to reserve capacity for data centres where competition for grid access is intense.

This matters for metals and electrical infrastructure suppliers. Faster data centre growth will increase demand for transformers, switchgear, copper and aluminium conductors, power cables, busbars, cooling systems, and grid reinforcement materials. The Frankfurt metropolitan area, already Germany’s largest data centre cluster, will remain a focal point for these constraints.

Energy Planning and Renewables Must Keep Pace With Digital Demand

Germany data centre capacity growth will only remain sustainable if renewable energy and grid infrastructure expand at the same pace. The strategy highlights the need to use existing infrastructure more efficiently while improving digitalisation at the distribution system operator level.

The new maturity-level procedure for large consumer grid applications is designed to create a clearer queue for major power users. Industry groups also support faster approval processes, early identification of priority areas, and better planning around water requirements.

For industrial supply chains, the message is clear. AI infrastructure is becoming a power-intensive manufacturing and materials story, not only a digital services story. As Germany scales AI and HPC capacity, the country will need more electrical metals, power equipment, cooling infrastructure, and grid-ready industrial zones.

The Metalnomist Commentary

Germany’s data centre strategy shows how AI growth is turning grid capacity into an industrial competitiveness issue. The winners will not only be cloud operators, but also suppliers of power equipment, conductors, transformers, and low-carbon electricity infrastructure.

Low-Carbon Aluminum Data Center Cables Advance Through Rio Tinto and Prysmian Trial

Prysmian low carbon aluminum

Low-carbon aluminum data center cables are moving from concept toward industrial validation as Rio Tinto and Prysmian complete a trial using cleaner aluminum feedstock. The partnership links primary aluminum production, cable manufacturing, and fast-growing electricity demand from digital infrastructure.

Rio Tinto produced aluminum rod for the trial using a blend of hydro-powered aluminum from its Alma smelter in Quebec and aluminum made through Elysis technology. Prysmian then used the material pathway to test low-carbon aluminum cable production for data center applications.

The trial forms part of a five-year supply agreement signed in 2023 between Rio Tinto and Prysmian. That deal focuses on low-carbon aluminum made with renewable hydropower from Rio Tinto’s Canadian operations.

Data Center Growth Raises Demand for Cleaner Conductors

Low-carbon aluminum data center cables matter because power infrastructure is becoming a larger part of the data center supply chain. Data centers require large volumes of cable, busbar, grid equipment, and electrical distribution systems as operators expand capacity for cloud computing and artificial intelligence.

Aluminum offers a strategic balance between conductivity, weight, cost, and availability. For cable manufacturers, lower-carbon aluminum can help reduce the embedded emissions of electrical infrastructure without changing the core role of aluminum as a conductor material.

Prysmian’s involvement is important because cable producers sit close to the final customer. If data center owners increasingly ask for lower-carbon materials, cable manufacturers will need stable access to verified low-carbon aluminum supply.

Elysis Technology Remains Strategic but Not Yet Scaled

Elysis aluminum gives the trial a deeper industrial meaning. The Rio Tinto and Alcoa joint venture is developing an emissions-neutral smelting process that could reduce the carbon footprint of primary aluminum production.

However, Elysis aluminum remains in development and is not yet available in large production quantities. This limits near-term commercial impact but supports longer-term qualification work with downstream users such as Prysmian.

Rio Tinto’s hydro-powered Canadian aluminum provides the scalable base for the current supply relationship. Elysis material adds a future-facing technology layer that could become more important if industrial buyers push harder for lower-emission metals.

The Metalnomist Commentary

Low-carbon aluminum data center cables show how digital infrastructure is reshaping metals demand beyond chips and servers. The next competitive advantage may come from verified low-carbon supply chains for the electrical backbone behind data centers.

New Casthouse at Karmoy to Support Europe’s Energy Transition with Sustainable Aluminium

Hydro to Launch 110,000 t/yr Aluminium Wire Rod Casthouse in Norway

Norwegian aluminium producer Hydro has unveiled plans to build a 110,000-ton-per-year aluminium wire rod casthouse at its smelter in Karmoy, Norway. This marks the company’s largest domestic investment in a decade, signaling its commitment to supplying the materials needed for Europe’s accelerating energy transition.

Set to begin production in Q1 2028, the new facility will manufacture low-carbon aluminium wire rod specifically designed for power cables. These cables are critical to the growing renewable energy infrastructure across the continent.

Hydro emphasized that aluminium's light weight, durability, and recyclability make it ideal for energy systems. Notably, aluminium conductors provide the same electrical conductivity as copper while weighing only half as much.

Surging Demand for Sustainable Aluminium in Energy Infrastructure

Hydro has observed rising demand for low-carbon aluminium in recent years, even as overall aluminium market activity remains subdued. The shift is driven by Europe’s push for sustainable energy transmission systems, which increasingly favor renewable materials.

“We see in our own sales figures an increasing awareness in the market that future renewable energy must be transported with renewable materials,” said Hydro CEO Eivind Kallevik. This trend aligns with broader decarbonization efforts within the European Union’s Green Deal framework.

Final Investment Decision Expected by Year-End

While the plan is progressing, Hydro stated that a final investment decision will be made in the fourth quarter of 2025. If approved, the Karmoy project will not only expand Hydro’s low-carbon product portfolio but also strengthen Norway’s role in Europe's clean energy material supply chain.

The Metalnomist Commentary 

Hydro’s strategic pivot toward low-carbon wire rod production is more than a manufacturing expansion—it's a signal to the broader metals industry. As governments and utilities demand greener grids, aluminium wire rod is quietly emerging as a frontline material for climate-resilient infrastructure. With weight and recyclability on its side, aluminium could challenge copper in critical grid applications. Hydro’s move reinforces how upstream aluminium strategies are now tightly linked to downstream energy policy.

India Renewable Curtailment Exposes Grid Bottleneck Behind Clean Power Growth

Ember

India renewable curtailment reached around 300GWh in January-March because of transmission constraints, showing that the country’s clean power buildout is now running ahead of grid readiness. The lost generation accounted for nearly two-thirds of India’s total renewable curtailment in the first quarter.

India renewable curtailment was concentrated in renewable-heavy northern and western grid pooling stations, especially Rajasthan and Gujarat. These regions have added large solar and wind capacity, but transmission expansion has not kept pace.

India renewable curtailment is strategically important because wasted clean power weakens project economics, increases peak power costs and delays the energy transition. It also highlights rising demand for grid materials, including copper, aluminium conductors, transformers, electrical steel and battery storage systems.

The curtailed volume represented around 1.5-2% of total renewable generation from interstate transmission system-connected plants in northern and western India. On 30 March alone, India lost 34GWh of renewable output because of insufficient transmission margins.

Transmission Delays Threaten Renewable Project Economics

India has achieved only around 80% of its annual transmission buildout targets over the past five years. That gap is now becoming visible in curtailment, grid connection delays and weaker returns for renewable developers.

One in four interstate transmission schemes scheduled for the 2026-27 fiscal year faces delays of at least one year. Around 20GW of renewable capacity is expected to face grid connectivity delays exceeding four months.

These delays carry direct financial consequences. A six to twelve-month delay in solar projects can reduce internal rates of return by 100-200 basis points because of lost early cash flows and higher financing costs.

The problem also affects India’s fuel import exposure. Curtailed renewable generation could have displaced costly gas-fired power during peak demand periods, reducing reliance on expensive LNG at a time when spot gas prices were elevated by the US-Iran war.

For metals markets, the message is clear. India’s renewable buildout now needs faster transmission investment, which means more demand for aluminium conductor, copper cable, transformers, substations, steel structures and grid equipment.

BESS Deployment Offers Near-Term Relief

Battery energy storage systems could provide a near-term solution at renewable pooling stations. Ember estimates that around 3-4GW of two-hour storage could absorb most curtailed renewable generation.

The economics are becoming more attractive. Stored solar power delivered at 7-8 rupees/kWh would remain below the Rs9-10/kWh many Indian states pay for peak-demand electricity.

This makes BESS deployment more than a technical fix. It is a cost-control tool, a grid-stability tool and a way to protect renewable project returns.

Battery storage demand also has materials implications. BESS deployment supports demand for lithium, phosphate, graphite, copper, aluminium, power electronics and thermal management systems, with lithium iron phosphate likely to remain important for stationary storage.

India’s southern region recorded no transmission-related renewable losses because renewable additions and transmission readiness were better aligned. That contrast shows that curtailment is not inevitable; it is a planning and execution problem.

India’s clean power transition will therefore depend on synchronising generation, transmission and storage investment. Solar and wind additions alone will not deliver energy security if power cannot move from renewable zones to demand centres.

The Metalnomist Commentary

India’s renewable curtailment shows that the energy transition is becoming a grid materials story. The next bottleneck is not only solar panels or wind turbines, but transmission capacity, storage deployment and the metals needed to move clean electricity.
