NALCO Signs EGA Licence to Double Aluminium Capacity to 1 MTPA

India’s largest state-owned aluminium producer has just committed to a technology path developed in the UAE, and the choice will double its smelting capacity. A decade ago that pairing would have seemed improbable. Today it signals how the global aluminium industry now sources its competitive advantage: through licensed, proven, high-amperage smelting platforms rather than in-house design.

National Aluminium Company (NALCO) signed a technology licensing agreement with Emirates Global Aluminium (EGA) on 7 September 2026 to deploy EGA’s proprietary DX+ Ultra high-amperage smelting system at its Angul facility in Odisha. The brownfield expansion will add 500,000 tonnes per annum of new output, lifting total capacity to roughly 1 million tonnes and making NALCO a meaningfully larger competitor in a domestic market dominated by Vedanta and Hindalco.

This is the first deployment of DX+ Ultra in India, and only the second international licensing of the technology after Aluminium Bahrain’s Line 6 expansion.

Here is what the deal actually involves: what the technology has already demonstrated at commercial scale, where the expansion fits within India’s aluminium ambitions, and the structural risks that sit between a signed licence and the first pot of new metal.

What NALCO and EGA agreed, and what each side gets from it

The agreement, signed in Dubai, is not a simple paper licence. EGA has committed to deliver a managed package across the project’s life.

Under the terms confirmed by NALCO’s press release, EGA will provide:

• The DX+ Ultra technology licence
• Technical know-how and proprietary process information
• Engineering designs for the smelter cells
• Implementation support across multiple project phases

Empty line noted. The seniority on both sides was clear. Chief General Manager (Projects) Biju K signed for NALCO, with Director of Projects and Technical Affairs Jagdish Arora and Director of Finance Abhay Kumar Behuria in attendance. EGA’s Acting Executive Vice President for Midstream operations, Abdalla Zarouni, signed on behalf of the licensor.

NALCO Chairman-cum-Managing Director Brijendra Pratap Singh set the ambition high.

“The Angul expansion using DX+ Ultra could rank among India’s most efficient aluminium smelting operations upon completion,” said Brijendra Pratap Singh, Chairman-cum-Managing Director of NALCO.

Because the scope covers engineering designs, commissioning support, and ongoing services rather than just intellectual property, NALCO is buying a supervised technology transfer. That matters for a state-owned enterprise with limited experience executing a smelter build at this scale. The execution risk that would normally shadow a first-in-country deployment is materially reduced.

The strategic calculus for each party

For NALCO, the logic is efficiency-led. The company had already been searching for a prebake, point-fed, high-amperage reduction-cell technology, the specific cell design proven to lower energy use per tonne and hold down capital cost per tonne on brownfield sites. DX+ Ultra fits that brief.

For EGA, the deal extends a licensing business that is now generating genuine multi-country traction. EGA first licensed its core process to Aluminium Bahrain in February 2016, and its technology booklet states it has licensed more than 500,000 tonnes of installed smelting capacity outside the UAE. NALCO becomes the second international licensee, and the first in India, monetising decades of in-house research as a tradable service that fits the broader Gulf push toward industrial diversification.

What DX+ Ultra actually delivers, and what Alba’s experience proves

Before NALCO commits half a million tonnes of new output to a single cell design, the relevant question is simple: what has this technology already produced under commercial conditions?

The technical differentiation starts inside the reduction cell. DX+ Ultra uses copper collector bar inserts in the cathode to cut cathode voltage drop and specific energy consumption. Modified busbars and reduced cell-to-cell distance let operators fit more pots into the same potroom, which lowers capital cost per tonne of capacity.

The performance envelope is documented. EGA started up a DX+ Ultra pot at 500 kA in its Eagle research section at Jebel Ali in May 2022, the first such achievement in the Middle East, signalling headroom well beyond current commercial deployment. Commercial potlines run in the 460-480 kA range.

The proof point that matters most is Aluminium Bahrain’s Line 6.

The single most striking outcome is the energy result.

Alba’s Line 6 produced roughly 26,000 tonnes more than initial projections with no increase in total energy consumption, according to EGA and Bechtel project summaries.

That is the benchmark NALCO’s engineers and investors should hold the Angul expansion against. It shows what the technology delivers when the power infrastructure is properly matched.

Alba Line 6 as the benchmark for Angul

Alba fitted 424 DX+ Ultra cells into a potroom that previously held 404 DX+ cells, purely through reduced cell spacing. That same brownfield constraint, adding capacity within an existing footprint, is exactly what NALCO faces at Angul.

The critical lesson is power. Alba’s result depended on a concurrent 1,800 MW power station built alongside Line 6. NALCO is developing its own captive power capacity in parallel, and the Angul outcome will hinge on whether that power investment matches the smelter’s appetite. The technology only performs when the electricity behind it does.

Where NALCO’s expansion fits in India’s aluminium ambitions

Doubling capacity is a genuine step up. It still leaves NALCO a distant third.

The current pecking order in Indian primary aluminium is clear. Vedanta leads at roughly 2.4 MTPA, expanding toward 2.8 MTPA. Hindalco sits at around 1.3 MTPA. NALCO’s Angul smelter carries a nameplate of 460,000 tpa and an operational figure of 480,000 tpa.

The sector’s ambition is large. Industry and government projections point to India moving from roughly 3.8-4.0 MTPA today to approximately 10 MTPA by 2030, requiring around 3 million tonnes of new smelter capacity across the three main producers, with demand growing at about 9% a year.

India’s aluminium demand-supply gap is the structural driver behind every capacity announcement in the sector, with domestic consumption growing at roughly 9% annually against primary production that has lagged for most of the past decade.

Reaching that target rests on several conditions the sector roadmap identifies:

• Securing low-cost, round-the-clock power
• Expanding domestic alumina refining capacity
• Integrating renewables, backed by a collective $5 billion investment targeting 20 GW by 2030
• Building downstream, value-added product capability

Odisha already holds around two-thirds of India’s aluminium capacity, so the Angul expansion reinforces an already concentrated geography rather than opening a new one. NALCO’s CMD framed the move within the national Viksit Bharat development vision.

Even at 1 million tonnes, NALCO remains well behind its private rivals. What changes is its category. NALCO shifts from a minor third player to a credible mid-scale producer with state backing, which strengthens its hand on power, logistics, and future downstream investment. For investors tracking Indian aluminium, the signal is that the state-owned sector is participating in the build-out cycle, not sitting it out.

The risks that complicate NALCO’s path to 1 million tonnes

The technology is proven. The power strategy behind it carries a multi-decade exposure that a July 2026 agreement has already locked in.

The dominant structural risk is coal. In July 2026, NALCO and NLC India signed a joint-venture-cum-shareholders’ agreement to build a 1,080 MW (4 x 270 MW) captive thermal power plant at Angul, under a 25-year power purchase agreement and a long-term coal fuel supply arrangement. The 0.5 MTPA expansion needs roughly 800 MW of additional captive power, so this plant is the engine of the new smelter.

The NALCO-NLC captive power JV formalised in July 2026 commits both parties to a 25-year commercial arrangement, locking in coal-based electricity as the backbone of the expanded smelter for the asset’s operating life.

What makes the choice notable is what preceded it. The power decision moved from optionality to commitment across three steps:

1. 2023: NALCO issued an Expression of Interest for around 1,100 MW of Angul smelter power, inviting coal-based captive generation over a 30-year period.
2. February 2024: NTPC and NALCO signed a non-binding MoU exploring coal, solar, wind, and storage to supply roughly 1,200 MW of round-the-clock power.
3. July 2026: NALCO and NLC India signed the binding JV for a coal-only 1,080 MW plant.

The renewable and storage options examined in 2024 did not survive into the final commitment. NALCO chose cost certainty over carbon flexibility.

Reclimatize’s May 2026 analysis rated the carbon risk of NALCO’s Angul expansion as “extreme,” describing the coal power plant as an explicit lock-in to coal-based electricity for 25 to 30 years.

That characterisation is not a peripheral footnote. It is a constraint on how NALCO can respond to carbon pricing and export tariffs over the life of the smelter.

Carbon policy and EU CBAM as compounding exposures

India’s own regulation arrives first. The country’s emission-intensity targets for the aluminium sector, elaborated by Prayas Energy Group, require a 4.8-4.9% reduction in smelter emission intensity by FY27 against an FY24 baseline. That obligation lands before the expanded Angul smelter is producing metal. NITI Aayog’s decarbonisation roadmap sets a longer pathway toward less than 4 tCO2 per tonne via indirect emissions and below 0.5 tCO2 per tonne via advanced smelting technologies.

Inert anode technology represents the longer-term alternative that producers like NALCO would need to consider if carbon pricing renders coal-backed Hall-Heroult smelting commercially unviable, with pilot deployments in the UAE and Europe demonstrating near-zero direct emissions from the reduction cell itself.

The forward trade risk is the EU’s Carbon Border Adjustment Mechanism (CBAM), the tariff scheme that prices the embedded carbon in imported goods entering the European market. Analysts single out coal-fired Indian aluminium as the most exposed to escalating CBAM charges. NALCO carries more of this risk than Hindalco, given the latter’s relatively more flexible renewable strategy. For any investor taking a long view on NALCO’s post-expansion economics, this exposure needs pricing in now, not later.

CBAM exposure for coal-fired aluminium producers is not static: the mechanism’s carbon price is linked to EU ETS allowance costs, which analysts project will rise through the late 2020s, compounding the cost disadvantage of smelters locked into coal-based power.

A deal that moves the dial, on capacity at least

The EGA agreement settles one big question for NALCO. The technology is chosen, it is commercially proven at Alba, and the managed transfer package reduces the execution risk that would otherwise haunt a first-in-India deployment. On the metal itself, the foundation is solid.

What the licence does not resolve is everything downstream of it. The 25-year coal PPA locks in a carbon exposure that India’s FY27 emission rules and a maturing EU CBAM will test directly. Doubling capacity to roughly 1 million tonnes still leaves NALCO far behind Vedanta’s 2.8 MTPA target. And the distance from a signed licence to competitive tonnes is filled with power and timeline variables the deal itself cannot answer. AlCircle reported no delays in the brownfield smelter as of mid-2025, while Reclimatize frames the current phase as the first step toward a possible 1.5 MTPA over time.

For investors, the story shifts from technology selection to execution. Three variables now matter most:

• Final investment decisions and delivery on the captive power supply
• NALCO’s compliance trajectory against India’s emission-intensity targets for the Angul smelter
• Any further EGA licensing announcements confirming DX+ Ultra’s momentum as a global platform

The licence is a credible start. It is the beginning of the execution story, not its conclusion.
