Steel and Aluminium Industry in Odisha
The Steel Industry
Odisha has emerged as the steel hub of eastern India, leveraging its unmatched combination of high-grade iron ore, thermal coal, cheap power, and port access. The state accounts for approximately 25 per cent of India’s installed steel-making capacity. The steel industry in Odisha spans the entire technology spectrum from large integrated steel plants using the blast furnace-basic oxygen furnace (BF-BOF) route to medium and small sponge iron and induction furnace units.
The Rourkela Steel Plant (RSP), the first integrated steel plant in the public sector in Odisha, was established in 1955 with West German collaboration and is now a unit of the Steel Authority of India Limited (SAIL). With an expanded capacity of about 4.5 million tonnes per annum (MTPA), RSP produces a wide range of flat and tubular products, and its plate mill is one of the few in India capable of producing high-strength plates for defence and strategic applications. Other major integrated plants include Tata Steel Kalinganagar (3 MTPA, with plans to expand to 8 MTPA), Jindal Steel and Power Limited (JSPL) at Angul (6 MTPA, based on the coal gasification-direct reduced iron route), Bhushan Steel (now BPSL) at Meramandali in Dhenkanal (5 MTPA), and the forthcoming JSW Steel plant at Paradip. Dozens of sponge iron and induction furnace units, particularly in the Sundargarh, Jharsuguda, and Jajpur districts, augment the steel-making capacity.
The steel plants source their iron ore primarily from the Keonjhar-Sundargarh belt (SAIL from its captive Bolani, Kiriburu, Meghahatuburu, and Barsua mines; private players from captive and merchant mines). Domestic thermal coal from the Talcher and Ib Valley coalfields is used for power generation and sponge iron making, but coking coal — essential for blast furnace operation — is almost entirely imported from Australia, Mozambique, and the United States. The steel produced is consumed in the domestic market (construction, infrastructure, automotive, and consumer durables sectors) with a significant portion exported through Paradip and Dhamra ports.
The Aluminium Industry
The aluminium industry in Odisha is synonymous with the state’s bauxite reserves and cheap captive power. Odisha houses the entire value chain from bauxite mining to alumina refining to aluminium smelting and downstream fabrication within the state, making it one of the world’s most cost-competitive locations for aluminium production.
National Aluminium Company Limited (NALCO) is the flagship public-sector aluminium company, with a fully integrated operation: bauxite mining at Panchpatmali (Koraput, 6.8 MTPA capacity), alumina refining at Damanjodi (2.275 MTPA), aluminium smelting at Angul (0.46 MTPA), and a captive power plant of 1,200 MW at Angul to supply the smelter. NALCO is one of the lowest-cost alumina producers globally, and it exports a substantial portion of its alumina and aluminium to Asia, Europe, and the Americas.
Vedanta Limited (formerly Sterlite Industries) operates a 2 MTPA alumina refinery at Lanjigarh (Kalahandi), sourcing bauxite from other states following the Supreme Court’s decision against mining at Niyamgiri. Vedanta also operates a 1.75 MTPA aluminium smelter and 1,215 MW captive power plant at Jharsuguda, making it the largest single-location aluminium smelter in India. Hindalco Industries (Aditya Birla Group) operates an alumina refinery at Sambalpur (using bauxite sourced from its captive mines in Koraput and Rayagada) and an aluminium smelter at Hirakud with associated captive power generation.
Ferroalloys and Downstream
The ferroalloys industry, producing ferrochrome, ferromanganese, and silicomanganese, is an important sub-sector that bridges mining and steelmaking. Odisha accounts for a dominant share of India’s ferroalloy production, centred on the Jajpur-Dhenkanal-Keonjhar belt, where chromite and manganese mines and cheap thermal power from Talcher create favourable locational conditions. Major producers include Tata Steel (Ferro Alloys), Indian Metals and Ferro Alloys Limited (IMFA), Jindal Stainless, Visa Steel, and numerous smaller units. The ferrochrome and ferromanganese produced in Odisha is consumed by stainless steel and alloy steel producers across India and is also exported.
Downstream fabrication and value addition in both steel and aluminium remain relatively underdeveloped in Odisha. Most of the intermediate products — steel slabs, hot-rolled coils, primary aluminium ingots — are transported to other states for rolling, extrusion, and fabrication into final products. Recognising this value leakage, the state has designated ‘Metal Downstream Parks’ at Kalinganagar (associated with Tata Steel) and Angul (associated with NALCO and JSPL) to attract investments in automotive components, construction systems, packaging, and electrical products. The development of a downstream ecosystem is central to Odisha’s industrial strategy.
Energy-Intensive Nature
A defining feature of both the steel and aluminium industries is their enormous energy intensity. Aluminium smelting, in particular, requires 14,000-16,000 kilowatt-hours of electricity per tonne of metal, making power cost the single most important determinant of competitiveness. The co-location of smelters with captive coal-based thermal power plants (Vedanta at Jharsuguda, NALCO at Angul, Hindalco at Hirakud) at pit-head locations has been the business model underpinning the success of the aluminium industry in Odisha. The carbon footprint of these industries is correspondingly large, and as India moves towards its net-zero commitments, the steel and aluminium industries in Odisha will need to progressively adopt green hydrogen-based reduction, renewable energy, and carbon capture technologies — a transition that will fundamentally alter the technological and economic landscape of the state’s industrial sector.
