• Renewable power consumption increases from ~18% in FY26 to current 22% of overall power consumption

• 530 MW round-the-clock renewable power arrangement to support transition towards 70% renewable power by FY28

• Clean energy adoption supports Hindustan Zinc’s SBTi-validated Net Zero 2050 or sooner ambition

Hindustan Zinc Limited, the world's largest integrated zinc producer and one of the world's top ten silver producers, has increased the share of renewable power in its current overall power consumption to 22%, up from approximately 18% in FY26, marking continued progress in its clean energy transition. The company is progressing towards meeting approximately 70% of its overall power requirements through renewable energy by FY28, as it scales clean energy adoption across its mining and smelting operations.

Across its business units in Rajasthan and Uttarakhand, Hindustan Zinc has continued to strengthen its renewable power generation capabilities. During FY26, the company generated 892 million units of green power, compared with 632 million units in FY25. The increase in green power generation, along with renewable power procurement, has contributed to the steady growth of renewable energy in the company’s overall power mix.

The company is progressing towards its ambition of sourcing 70% of its total electricity requirements from renewable sources by FY28. To support this target, Hindustan Zinc expanded its round-the-clock renewable energy power delivery agreement with Serentica Renewables from 450 MW to 530 MW. In addition, Hindustan Zinc is advancing its energy transition by upgrading power connectivity from the state transmission network to the central transmission utility, alongside implementing innovative in-house projects that support a cleaner, more resilient and energy-efficient future. Key initiatives include enhancing waste heat recovery boiler steam turbine generation through efficiency improvements and harnessing renewable energy through floating solar installations on water ponds

The organization’s renewable energy portfolio combines solar, wind and energy storage solutions to enable reliable round-the-clock clean power across the company’s operations. The arrangement is expected to progressively increase the contribution of renewable energy to Hindustan Zinc’s overall power mix as additional capacity is integrated.

Highlighting the company’s accelerating clean energy transition, Mr. Amarendu Prakash, CEO, Hindustan Zinc, said “The next chapter of growth in metals and mining will be defined by our ability to produce more with a progressively lower environmental footprint. With renewable power now accounting for 22% of our power consumption and our ambition to take this to 70% by FY28, we are demonstrating that clean energy is not simply a decarbonization lever; it is fundamental to creating a more resilient, competitive and responsible business. By transforming the way we power our operations, we are strengthening Hindustan Zinc for a low-carbon future while supporting India’s journey towards energy security and a Viksit Bharat.”

These efforts form an integral part of Hindustan Zinc's broader sustainability roadmap and support its Science Based Targets initiative (SBTi)-validated decarbonisation pathway towards achieving Net Zero emissions by 2050 or sooner. During the year, the company continued to strengthen its position as a sustainability leader, building on its recognition as the world's most sustainable metals and mining company by the S&P Global Corporate Sustainability Assessment and its membership of the International Council on Mining and Metals (ICMM), the highest global benchmark for responsible mining.

Hindustan Zinc, a Vedanta Group company, advances its next phase of growth and moves towards a multi-metal future, clean energy will remain central to its strategy of producing metals essential for India’s growth and the global energy transition through increasingly sustainable and responsible operations.
