A Comprehensive Overview of Smelters, Downstream Industries, and Emerging Investments
According to the Vision Document on Aluminium Metal for India, the nation has achieved significant capacity in aluminium production, currently producing 4.16 million tonnes per annum (Mtpa) of primary aluminium and 1.8 Mtpa in the secondary sector.
At the forefront of this growth stands Odisha, which has emerged as the epicentre of India’s aluminium industry, hosting four major aluminium smelters with a combined installed capacity of 2.7 Mtpa.
Major Aluminium Smelters Operating in Odisha
1. NALCO Aluminium Smelter, Angul (0.46 Mtpa)
The smelter operated by National Aluminium Company Ltd. (NALCO) at Angul is based on the Aluminium Pechiney (AP-18) technology, comprising four potlines with 240 electrolytic cells each. The facility integrates casting units for ingots, sows, billets, strips, wire rods, and chequered sheets.
A 50,000 tpa Rolled Products Unit (RPU), connected directly to the smelter via molten metal transfer, produces cold rolled sheets and coils using FATA Hunter (Italy) technology. The unit specialises in chequered sheets for industrial use.
The smelter is supported by a 1,200 MW captive thermal power plant, ensuring uninterrupted supply of electricity for its operations.
2. HINDALCO Hirakud Aluminium Smelter, Sambalpur (0.216 Mtpa)
Located in Sambalpur district, the Hirakud Smelter is India’s oldest operational aluminium smelter, commissioned in 1959.
It consists of five potlines and 12 rooms housing 785 pots, operating on GAMI pre-baked technology. The plant is linked to five casting houses and draws power from a coal-based captive power plant.
3. HINDALCO Mahan Aluminium Smelter (0.371 Mtpa)
The Mahan Smelter, operational since 2013, is an integrated complex employing AP36 Pechiney technology (France) for its smelter and Solios technology for its carbon plant.
The associated captive power plant (6×150 MW) is powered by BHEL systems, supporting full production since 2015.
4. HINDALCO Aditya Aluminium Smelter, Lapanga (0.38 Mtpa)
A flagship facility at Lapanga (Sambalpur), the Aditya Smelter has a capacity of 0.38 Mtpa and is powered by a 900 MW captive plant.
It uses AP-36S RTA technology (France), designed for high-efficiency operations at 368 kA current, featuring advanced controls and safety systems.
5. VEDANTA Aluminium Smelter, Jharsuguda (1.8 Mtpa)
Vedanta Aluminium operates India’s largest aluminium smelting complex at Jharsuguda (Odisha) and Korba (Chhattisgarh) through BALCO.
The Jharsuguda SEZ complex offers export-oriented infrastructure and is central to Vedanta’s aluminium growth strategy.
Odisha’s Thriving Aluminium Downstream Ecosystem
Odisha has evolved into India’s leading aluminium downstream hub, transforming primary metal (ingots, billets, wire rods) into value-added products including sheets, coils, foils, extrusions, castings, conductors, and can stocks.
Key downstream industries include:
-
HINDALCO Hirakud FRP Unit – Produces flat-rolled products for automotive, packaging, and industrial applications, using cold rolling and continuous casting technologies.
-
Dhaatu Fabex Pvt. Ltd. (Angul Aluminium Park) – Manufactures custom extrusions using direct molten metal feed from NALCO’s smelter, enhancing energy efficiency.
-
Narayan Aluminium Alloy Pvt. Ltd. – Specialises in anodised and powder-coated extrusions, operating 900-ton and 1650-ton presses for industrial profiles.
-
Alom Group (UML Balasore) – Operates two extrusion units and a fabrication facility for solar frames and architectural hardware, with 14,000 TPA capacity.
-
APAR Industries (Jharsuguda) – Runs a large-scale aluminium cable manufacturing unit.
Vedanta Aluminium Park, Jharsuguda
A 253-acre integrated industrial park developed jointly by Vedanta Ltd. and IDCO, this park enables MSMEs to source hot metal directly from the smelter, significantly reducing reheating and energy costs. Equipped with logistics, utilities, and R&D support, it’s driving MSME-led value addition in aluminium.
NALCO Angul Aluminium Park
A joint venture of NALCO and IDCO, this 450-acre park—the first of its kind in India—offers direct molten and solid aluminium supply to downstream units.
The park focuses on conductor manufacturing, extrusions, castings, and foils, and is set to revolutionize the downstream value chain by reducing carbon emissions (by 60,000–70,000 tonnes annually) through energy-efficient molten metal transfer.
Mega Investments and Future Outlook
By 2025, Vedanta Ltd. has pledged investments worth US$ 15.5 billion in Odisha’s aluminium sector, expected to create over 200,000 direct jobs, strengthening industrial and employment growth.
The Government of Odisha is drafting a dedicated downstream aluminium policy, encouraging diversification into calcined petroleum coke (CPC), aluminium fluoride, and coal tar pitch, aiming to catalyse innovation, sustainability, and value addition.
Bauxite Expansion & Upcoming Projects (By 2030):
-
India’s bauxite production is expected to double to 50 Mtpa, largely from Odisha’s Eastern Ghats.
-
Sijimali (Vedanta), Kuturmali & Ballada (Adani) have been allotted for development.
-
Karlapat and Nunapaimali blocks are in auction stage.
-
Brownfield expansions:
-
NALCO (Damanjodi): 2.3 → 3.3 Mtpa
-
Vedanta (Lanjigarh): 3.5 → 5.0 Mtpa
-
HINDALCO (Utkal): 2.0 → 2.5 Mtpa
-
-
Greenfield projects:
-
HINDALCO-OMC (Kansariguda)
-
Vedanta (Sijimali, 6 Mtpa)
-
Adani & Kalinga Alumina Ltd. (KAL)

Conclusion: Odisha’s Aluminium Advantage
Holding 59% of India’s bauxite reserves, Odisha has built a vertically integrated aluminium value chain, from bauxite mining and refining to smelting and downstream manufacturing.
World-class refineries (NALCO, Vedanta, Hindalco), smelters (2.7 Mtpa), and parks (Angul, Jharsuguda) make the state a powerhouse of global competitiveness.
Future growth will focus on:
-
30% renewable energy transition for smelters/refineries by 2030
-
Dedicated rail corridors linking mines, refineries, and ports
-
Conveyor networks for efficient ore transport
Odisha’s synergy of natural resources, industrial infrastructure, and policy vision firmly establishes it as India’s Aluminium Capital—driving Atmanirbhar Bharat and positioning the state as a global hub for sustainable aluminium production.
