Hindustan Zinc Ltd. has strengthened its renewable energy commitment by expanding its power delivery agreement with Serentica Renewables, increasing its round-the-clock renewable energy supply to 530 megawatts from an earlier 450 MW, the company said on Tuesday.

According to a statement, the expanded capacity will push Hindustan Zinc’s renewable energy contribution to over 70 percent of its total power needs, marking a significant step toward its target of achieving net-zero emissions by 2050 or earlier.

Under the agreement, Serentica will provide at least 315 MW of uninterrupted power in each 15-minute time block, ensuring a stable and dispatchable power supply through a mix of solar, wind and energy storage technologies.

The project, developed under a captive structure, will be fully operational by 2027, with installations spread across high-resource locations in India.

Climate Action Strategy

“This agreement marks a significant step in our climate action strategy,” Hindustan Zinc CEO Arun Misra said in the statement. “By securing 70 percent of our power from renewables, we are targeting a nearly 70 percent reduction in carbon emissions.”

Serentica Renewables CEO Akshay Hiranandani called the agreement a breakthrough, addressing intermittency challenges and ensuring Hindustan Zinc has a firm, reliable power supply.

The company recently started receiving renewable power from Serentica’s 180 MW solar park, which was used in the production of Asia’s first low-carbon ‘green’ zinc, branded as EcoZen.

Sustainable Manufacturing

Last month, Hindustan Zinc was featured in the S&P Global Sustainability Yearbook 2025, securing a top 1 percent ranking for the second consecutive year for its commitment to sustainable manufacturing.

Notably, the company remains committed to achieving net zero by 2050 or sooner. The mining giant achieved a 14 percent decrease in greenhouse gas emission intensity compared to the base year 2020 while increasing production each year.

The company is taking significant strides towards sustainability by outlining plans to raise its renewable contribution to over 70 percent of its total power requirement by 2027.
