The company showcases significant achievements in reducing energy consumption, optimizing processes, and driving GHG reductions, underscoring its role as a leader in sustainable industrial practices

Marking Energy Conservation Week, initiated by the Bureau of Energy Efficiency (BEE), Vedanta Aluminium, India’s largest producer of aluminium, announced achieving an impressive 1.3 million Giga Joules (GJ) of energy savings through innovative measures aimed at enhancing energy efficiency and reducing greenhouse gas (GHG) emissions. The company achieved a remarkable 10.16% reduction in GHG intensity against the 2021 baseline, positioning it as a frontrunner in the global effort to reduce carbon emissions. Further driving its sustainability agenda, the company announced sourcing 1.3 GW of renewable energy, marking a major step towards a cleaner, more sustainable operations.

Vedanta Aluminium has implemented several key initiatives to enhance sustainability and operational efficiency in its potlines, where molten aluminium is produced from alumina through electrolysis. These initiatives include installing graphitized cathode enhancements to reduce current consumption, lower GHG emissions, and improve operational efficiency. The company has also deployed indigenously-developed Vedanta pot controllers that reduces energy use by 200–250 kWh per tonne of aluminium. Moreover, the company has reduced specific coal consumption in its power plants to cut GHG emissions and enhance power efficiency. By optimizing smelting processes to promote energy-efficient operations, Vedanta Aluminium is promoting sustainable industrial practices as part of its broader sustainability goals.

Commenting on these activities, Sunil Gupta, Chief Operating Officer, Vedanta Aluminium, said, “At Vedanta Aluminium, energy management is central to our net-zero journey. Innovations like the patented ‘Vedanta Lining Design’ for smelting pots and expanding renewable energy adoption, we are enhancing our efficiency and lowering carbon emissions. Ranking 1st in the S&P Global Sustainability Assessment for the year 2023 reflects our belief that industrial progress must go hand-in-hand with environmental responsibility. Energy Conservation Week reaffirms our resolve to pioneer sustainable practices for a greener future.”

At its refinery operations in Lanjigarh, Odisha, boilers were replaced with advanced graphitized pots to enhance energy conservation. At its smelter operations in Jharsuguda, Odisha, the company successfully reduced cathode voltage drop and implemented Voltage Drop (VLD) measures in pots, improving both performance and energy efficiency. Similarly, at its BALCO smelter in Korba, Chhattisgarh, cathode relining and graphitization initiatives were executed, significantly boosting energy efficiency across the facility.

Moreover, to sensitise employees, Vedanta Aluminium has implemented a comprehensive energy efficiency training initiative across its operations. By engaging its extensive employee base through various awareness initiatives, the company seeks to optimize energy use, while adhering to international standards such as ISO 50001 for Energy Management.
