India: Hindalco steps up aluminium integration with INR 21,000-crore smelter expansion and downstream push

• Smelter expansion strengthens upstream base in Odisha
• Battery foil and FRP units target EV and energy storage supply chains

Hindalco Industries has announced a major expansion of its aluminium operations in Odisha, underlining its confidence in India’s long-term demand for primary metal and high-value downstream products. The company will invest INR 21,000 crore to add 360,000 tpa of smelting capacity at its Aditya Aluminium complex in Sambalpur, while commissioning 170,000 tpa of flat rolled products (FRP) and battery-grade aluminium foil capacity at an additional cost of around INR 4,500 crore.

The new downstream facilities mark a strategic shift toward value-added aluminium. The battery-grade foil plant would be India’s first dedicated facility of its kind and is designed to support up to 100 GWh of lithium-ion cell manufacturing capacity, directly aligning Hindalco with the country’s rapidly expanding electric mobility and energy storage ecosystem. Company officials indicated that the FRP unit will feed the foil facility, improving conversion efficiency and product consistency.

India currently imports close to 40% of its flat-rolled aluminium requirements. With Hindalco accounting for over half of domestic FRP supply, the expanded capacity is expected to halve import dependence over time, improving supply security for sectors such as EVs, defence, packaging, renewables and advanced manufacturing. A senior industry participant noted that “local availability of battery foil could materially reduce costs and lead times for cell manufacturers setting up in India.”

On the upstream side, the Sambalpur smelter expansion strengthens Hindalco’s integrated model linking bauxite, alumina and primary aluminium with downstream products. Part of the smelter’s power requirement is planned to be met through round-the-clock renewable energy, which could help manage cost volatility in a power-intensive segment.

The Odisha projects form part of Hindalco’s broader INR 55,000-crore growth capex pipeline across India, with about INR 37,000 crore earmarked for the state. Combined, the investments are expected to generate more than 15,000 direct and indirect jobs, reinforcing Odisha’s position as a key aluminium hub.
