India Secondary Aluminium: The 10-Fold CBAM Advantage of the Scrap Route and Business Case
India's three primary aluminium producers have projected capacity targets that would nearly triple the sector from 3.8 MMT to 10 MMT by 2030. Every tonne added via conventional coal captive power carries approximately €680 of CBAM liability per tonne of EU-exported metal. The 10 MMT ambition and the European market remain structurally incompatible unless the expansion pivots systematically to renewable electricity.
Key Takeaways
- India's primary aluminium capacity is ~3.8-4.0 MMT/year. The sector's combined expansion projections approach 10 MMT of total capacity by 2030, representing an addition of roughly 6 MMT and requiring an electricity supply of about 87 billion additional units per year at full capacity.
- Vedanta targets roughly 3 MMT of additional capacity. With a current RE share of ~3-5%, expanding on coal locks in CBAM embedded emissions of 14-18 tCO₂/t, making EU market participation unviable.
- Hindalco occupies a differentiated position. With ~10-15% current RE share and advanced evaluations for 1 GW RTC RE, its expansions possess better grid RE access than deep-inland Odisha operations.
- NALCO recently signed a 1,080 MW coal CPP MOU in February 2026. Commissioning this post-CBAM definitive period locks in a ~1.0 tCO₂/kWh emission factor for 25-30 years, creating extreme structural exposure.
- A 10 MMT coal-based sector exporting 35-40% to the EU would face an estimated annual CBAM bill of €2.4 to €2.8 billion, effectively pricing the coal-based increment out of Europe.
- Powering the 6 MMT expansion via green aluminium requires 35 to 45 GW of blended RTC renewable capacity (solar, wind, storage), demanding unprecedented parallel infrastructure execution.
India's aluminium sector sits at the intersection of two incompatible trajectories. On one side, India's industrial policy and domestic demand growth, driven by automobiles, packaging, construction, and power transmission, support a well-grounded ambition to grow primary aluminium production to 10 million tonnes per year by 2030. This expansion aims to cement India's position as the world's second-largest producer and capture the value-added production that currently flows through imports. On the other side, CBAM has turned the electricity source for every tonne of that expanded production into a critical financial variable, with the power to determine whether EU market access remains economically possible. The two trajectories will only be compatible if India's aluminium expansion functions simultaneously as a renewable energy expansion rather than a coal capacity expansion with a renewable aspiration attached.
The distinction between these two approaches, integrated renewable-with-smelter expansion versus coal-with-renewable-aspiration, forms the central analytical question for India's aluminium sector in 2026. Every company has announced renewable energy commitments. However, not every company has a credible timeline, capital commitment, and grid connection plan that keeps pace with its smelting capacity additions. Understanding which companies are genuinely integrating renewable electricity into their expansion programmes and which are announcing targets without a delivery plan provides the starting point for any assessment of India's aluminium sector's EU market competitiveness through 2034.
Company-by-company expansion and renewable electricity assessment
India Primary Aluminium: Capacity Expansion Plans vs RE Trajectory (Oct 2026)
| Producer | Current Capacity | 2030 Target | Expansion Delta | Current RE Share | RE Commitment for Expansion | CBAM Exposure Assessment |
|---|---|---|---|---|---|---|
| Vedanta (Jharsuguda) | ~2.4 MMT (inc. BALCO) | ~5.0 to 5.5 MMT | plus 2.6 to 3.1 MMT | 3 to 5% | Targeting 4-5 GW RTC power via Serentica; full scaling remains unverified | Very High: coal CPP dominant; locks in CBAM exposure |
| Hindalco (Portfolio) | ~1.3 MMT | ~2.5 to 3.0 MMT | plus 1.2 to 1.7 MMT | 10 to 15% | Evaluating 1 GW RTC RE + pumped hydro; better regional grid access | High but reducing: RE commitments more credibly paced with expansion |
| NALCO (Angul) | ~0.46 MMT | ~1.5 MMT | plus 1.0 MMT | 8 to 10% | 1,080 MW coal CPP MOU signed Feb 2026 | Extreme: new coal CPP post-CBAM definitive period is the sector's most exposed decision |
The CBAM arithmetic on the expansion: what each scenario costs
The financial stakes of getting the electricity mix wrong on the expansion are large enough to deserve explicit quantification at the sector level. The table below evaluates three electricity scenarios for the expanded 6 MMT increment, assuming an €80/tCO₂e price, an 8.0 tCO₂/t EU benchmark deduction, and a 40 percent export ratio to the EU.
CBAM Cost Impact: Three Scenarios for the 6 MMT Expansion (EU ETS at €80/tCO₂e)
| Electricity Scenario | Scope 2 EF | Total Embedded Emissions | CBAM Cost/t (Excess over 8.0) | Annual CBAM Bill (EU exports) |
|---|---|---|---|---|
| All-coal CPP (expansion on coal) | ~1.0 tCO₂/MWh CPP | ~16.5 tCO₂/t aluminium | ~€680/t | ~€1.63 bn/year |
| 50% renewable (blended CPP + RE) | ~0.50 tCO₂/MWh blended | ~9.5 tCO₂/t aluminium | ~€120/t | ~€288 mn/year |
| 100% renewable (captive solar/wind) | ~0.02 tCO₂/MWh RE | ~2.2 tCO₂/t (Scope 1 only) | €0/t (Below Benchmark) | €0/year |
The difference between the all-coal and 100 percent renewable scenarios represents over €1.6 billion per year in CBAM certificates on the expansion increment's EU exports alone. This figure, which amounts to approximately Rs 14,500 crore annually on an ongoing basis, dictates the economic viability of the renewable energy infrastructure required to power the expansion. At an installed cost of approximately Rs 2.5 to 3.5 crore per MW and a blended round-the-clock renewable requirement of 35 to 45 GW for the 6 MMT expansion at full scale, the capital required for the renewable build hits roughly Rs 1,00,000 to 1,40,000 crore. Over a 20-year asset life, and measured against Rs 14,500 crore of annual CBAM savings, this represents a highly attractive carbon payback period of approximately 7 to 10 years, even before factoring in basic electricity cost savings or domestic CCTS compliance benefits.
NALCO's 1,080 MW coal captive power plant decision in context.
NALCO's signing of the 1,080 MW thermal captive power plant MOU with NLCIL in February 2026, just five weeks after CBAM legally entered its financially live definitive period on January 1, 2026, stands as one of the most consequential single decisions in India's aluminium sector's trade history. A 1,080 MW coal captive plant at 1.0 tCO₂/kWh supplying a 1 MMT smelter expansion generates Scope 2 embedded emissions of approximately 14.5 million tCO₂e per year. Assuming the 8.0 tCO₂/t EU benchmark deduction against total emissions (14.5 Scope 2 + 2.2 Scope 1 = 16.7 tCO₂/t), at €80/tCO₂e and a 40 percent EU export ratio, the annual CBAM obligation added by this one plant choice sits at exactly €278.4 million every single year for the operational life of the facility. NALCO's management and its supervisory Ministry of Mines must conduct a rigorous NPV analysis of the captive power decision against the renewable alternative before construction begins. The Rs 6.7 crore daily CBAM liability that this asset would impose on NALCO's EU-exported aluminium may emerge as the most expensive single capital decision a public sector company makes in 2026.

Frequently Asked Questions
Why does India want to expand aluminium capacity to 10 MMT if CBAM makes coal-based expansion uncompetitive in the EU?
The 10 MMT target is driven primarily by domestic market growth projections, not EU export ambition. India's domestic aluminium consumption is projected to grow from approximately 4 MMT today to 7 to 8 MMT by 2030, driven by electric vehicle battery casings, packaging, solar panel frames, and power transmission cables. The domestic market expansion is not subject to CBAM; it is driven entirely by India's internal demand growth and the government's import substitution policy. The CBAM problem only arises for the fraction of the expanded capacity that is exported to the EU, which is currently approximately 35 to 40 percent of total production. The expansion target is strategically sound for domestic market supply; the CBAM exposure is specifically on the EU export portion, and the answer to that exposure is renewable electricity, not smaller production ambitions.
What is the CCTS GEI target expected for aluminium when it is notified?
The CCTS GEI targets for aluminium were notified by MoEFCC under the Greenhouse Gas Emission Intensity Target Rules 2025 in October 2025. The specific numerical thresholds for aluminium GEI reduction percentages have been notified for 282 entities in four sectors including aluminium, setting FY2025-26 and FY2026-27 baseline trajectories derived from the FY2023-24 sectoral baseline. The intensity reduction percentages for aluminium are modest in Phase 1, roughly 1 to 3 percent per year, reflecting the sector's current high emission intensity and the government's intent to ratchet targets more aggressively in Phase 2. Producers investing in renewable electricity will over-achieve Phase 1 targets and generate a CCC surplus; producers relying on coal captive power will find themselves acting as compliance buyers from Phase 1 onwards.
Is there a realistic pathway for India to achieve 10 MMT of aluminium production with renewable electricity by 2030?
Technically yes, but it remains financially and logistically challenging on that timeline. India's renewable capacity addition is currently running at approximately 40 to 50 GW per year. Dedicating 35 to 45 GW of that capacity to aluminium smelter power supply would require either massive captive installations or very large-scale open access procurement contracts. Odisha's specific cross-subsidy concessions make the state's existing renewable framework a viable deployment pathway. The realistic scenario points to 7 to 8 MMT of capacity by 2030 with approximately a 30 to 40 percent renewable electricity share across the sector, not 10 MMT all-renewable by 2030. The 2035 NDC trajectory and the CCTS Phase 2 targets will drive the remaining transition in the second half of the decade.
