Hindalco Industries Ltd, the metals flagship of the Aditya Birla Group, has announced a Rs. 21,000-crore, 3.6 lakh-tonne-per-annum smelter expansion at its Aditya Aluminium complex in Sambalpur and commissioned a 1.7 lakh-tonne-per-annum Flat Rolled Products (FRP) and battery-grade aluminium foil manufacturing facility with an investment of Rs. 4,500 crore.

The projects were inaugurated by the Chief Minister of Odisha, Mohan Charan Majhi.

These projects are a major step in indigenising critical raw materials for lithium-ion batteries in India, supporting the electric mobility and energy storage ecosystem, while enhancing domestic capabilities in high-grade aluminium products. The battery-grade aluminium foil facility—India’s first of its kind—draws input directly from the FRP complex and is designed to support up to 100 GWh of lithium-ion cell manufacturing capacity.

These projects form part of Hindalco’s broader growth capital expenditure programme, with around Rs. 37,000 crore planned for Odisha across upstream and downstream aluminium operations. The Odisha investments are a significant component of the company’s overall growth capex of Rs. 55,000 crore across India.

Commenting on the development, Kumar Mangalam Birla, Chairman, Aditya Birla Group said, “India’s manufacturing growth depends on integration, value addition and sustainability. Through Hindalco, we are building a fully integrated aluminium ecosystem that spans from upstream resources to high-value downstream products. Our long-standing partnership with Odisha continues to play an important role in this journey. This strategy strengthens India’s self-reliance, supports critical sectors, and accelerates the nation’s transition towards advanced, sustainable manufacturing.”

Satish Pai, Managing Director, Hindalco Industries Ltd. said, “The FRP expansion and smelter growth at Sambalpur exemplify our integrated upstream–downstream growth strategy. This enables Hindalco to deliver high-quality aluminium solutions across packaging, defence, electric mobility, renewable energy and advanced manufacturing, positioning us strongly to support India’s industrial ambitions while creating long-term value.”
