NALCO’s ₹30,000 Cr Capex: Can It Be the Next Leader in...

Synopsis: The National Aluminium Company Limited is entering a decisive investment cycle after delivering record FY26 performance. With a ₹30,000 crore aluminium expansion, a new alumina stream, rising domestic sales, captive resource security, and pilot projects in gallium and rare earth extraction, NALCO is positioning itself beyond aluminium toward becoming a broader strategic materials player.

India’s push toward energy transition, infrastructure, semiconductors, and strategic minerals is creating new opportunities for metal producers, and National Aluminium Company Limited appears ready to capitalise on that shift. After posting its best-ever operational and financial performance in FY26, the company has unveiled ambitious plans spanning a ₹30,000 crore smelter expansion, higher alumina capacity, stronger domestic market penetration, captive resource security, and early-stage projects in gallium and rare earth recovery, signalling a transformation that could define its next decade.

With a market cap of Rs 76,890 crore, the shares of National Aluminium Company Ltd are trading at Rs 419 and are trading at a PE of 12.5. The shares have given a return of more than 450% in the last 5 years.

A Record Year Sets the Stage

FY26 not only saw another successful year for NALCO, but it also saw what management called an “historic year” where the company had its best-ever performance on all operational and financial measures.

As far as operation is concerned, the firm saw positive growth in terms of bauxite excavation, alumina hydrate production, calcined alumina production, metal production, thermal power generation, and wind power generation. In terms of production numbers, bauxite production was up 6%, whereas alumina hydrate and calcined alumina were up 11.5%.

Production of aluminium metal was up 2.61%, captive coal production was up 41.84%, thermal power was up 4.7%, and wind power was up 9.25%. Sales-wise, the sales of alumina went up 30.74%, while those of aluminium metal were up 2.8%.

Financially, the revenue from operations was up from ₹16,788 crore to ₹17,843 crore; the EBITDA increased to ₹8,613 crore, profit before tax to ₹7,767 crore, and the profit after tax to ₹5,816 crore, which was an increase of 9.22% from last year’s number.

The New Smelter Vision

The largest strategic move announced during the earnings call pertained to the implementation of the new 0.5 million tonne aluminium smelter project, which has been termed a crucial growth plan for the company.

The detailed project report is being drafted, while the technology licensor is expected to be determined by September-October FY27. By then, the company will also complete the DPR approval, board approvals, and the tendering process for the new smelter plant.

Execution at ground level can start as early as April-May of the following year, while commercial commissioning may commence by December 2030 or January 2031. In this regard, it is pertinent to note that the company has already taken its present aluminium manufacturing facilities beyond the nameplate capacity of 4.6 lakh tonnes to manufacture 4.71 lakh tonnes of the metal.

Inside the ₹30,000 Crore Bet

Management also indicated that this would not be a small brownfield investment. While the initial investment requirement for the new aluminium smelting plant, along with power infrastructure, is estimated to be around ₹30,000 crore, after considering the joint venture formation in the case of the power segment, the net impact on NALCO could reduce to around ₹23,000 to ₹24,000 crore.

The capital expenditure in FY27 will stand around ₹1,800 to ₹2,000 crore, which would jump to ₹4,000 to ₹5,000 crore in FY28. However, the true peak in capex might take place in FY29 and FY30, when capex could amount to ₹8,000 to ₹10,000 crore.

The Fifth Stream Begins

Though the smelter will take longer, the immediate growth can come from NALCO’s fifth alumina refinery stream, which is likely to start commissioning in June itself and will need three to four months more to stabilise.

The management aims for an additional 2 lakh tonnes of alumina in FY27, which would take the total alumina production to about 25 lakh tonnes. With accelerated commissioning, the production may go even higher.

More importantly, the additional capacity of alumina will provide NALCO with the ability to use it for exports as well as for captive use once the aluminium smelter starts operations in the coming years.

Building New Alumina Markets

This is not just an expansionary approach, but one of altering the destination of production as well. According to management, domestic sales of alumina grew from a mere 40,000 tonnes in FY25 to a much larger 1.4 lakh tonnes in FY26, representing an increase of 1 lakh tonnes, with the plan being to ramp up domestic sales to 2.5-3 lakh tonnes in FY27.

Alongside that, NALCO is also seeking to establish long-term supply agreements with smelters across the globe. What makes this essential is that any problems in the Middle East region have impacted the area which accounts for 40-50% of NALCO’s alumina exports.

NALCO’s Gallium Opportunity

Apart from aluminium, another significant revelation was made regarding the recovery of gallium. According to management, NALCO has already started the process of gallium recovery and currently stands at an advanced level of establishing a pilot plant for this purpose.

Gallium, which is a rare mineral used for manufacturing semiconductors, defence equipment, and high-end communication systems, is being increasingly recognised as a strategic metal across the globe.

As per the information given by the management, the project is making good progress, and within the next two or three years, NALCO may be able to establish a gallium factory on a commercial scale.

Turning Red Mud into Value

The gallium project is just one of many efforts surrounding rare earths and critical minerals. According to management, “NALCO has huge amounts of red mud”, which is the waste product generated during alumina production, and “Several pilot projects are ongoing” to recover valuable minerals from this source.

While these projects currently operate at a pilot scale, management indicated that it may take up to two to three more years for the company to prove its commercial feasibility.

However, the potential cannot be overstated. Should even a small portion of these mineral recovery projects succeed commercially, then NALCO would be able to turn the waste into gold, turning a negative into a positive source of value for the company.

What the Next 5 Years Could Look Like

Bringing all the pieces together, one can conclude that the next five years for NALCO will revolve around four main pillars, which include capacity building, energy security, diversification of products, and strategic metals.

The company has plans for setting up an alumina stream; creating a new aluminium smelter with a capacity of 0.5 million tonnes; embarking upon a capex cycle with an investment of ₹23,000 crore to ₹30,000 crore; sourcing coal by means of captive mining, which is likely to expand its production from 4 million tonnes to 4.8 million tonnes; and having a degree of flexibility in the mining of gallium and rare earths.

Conclusion

NALCO’s vision of the next five years does not simply revolve around the production of aluminium. It involves expanding its integrated metals platform, sourcing raw materials, increasing its downstream capacity, looking into critical minerals of high value, and positioning itself to capitalise on the capex cycle that will coincide with the spike in demand for aluminium, semiconductor materials, and energy transition metals.

With successful implementation, the company that currently stands out as the aluminium leader in India may very well become a much bigger entity in the coming decade, namely, a strategic materials platform based on aluminium, gallium, and rare earths.
