Vedanta group-owned Hindustan Zinc Ltd is going big in clean energy. On 11 March, 2025, it announced a new deal with Serentica Renewables to provide as much as 530 MW of green power. Following a deal that was earlier inked for 450 MW, the company’s portion of renewable energy is now over 70% of its total power demand. It’s one giant leap towards making India’s mines sustainable.
A Game-Changing Agreement
The power delivery agreement (PDA) is unique. “This is a first-of-its-kind round-the-clock renewables PDA that guarantees a minimum of 315 MW uninterrupted power supply through every 15-minute time block,” Hindustan Zinc stated in a filing to the BSE. The project will combine new solar, wind, and energy storage systems across multiple sites.
Driving Toward Net Zero
Hindustan Zinc is serious about cutting emissions. “This agreement marks a significant step in our climate action strategy. By securing 70 per cent of our power from renewables, we are targeting nearly 70 per cent reduction in carbon emissions, setting sights on our goal of achieving net zero by 2050 or sooner,” said Hindustan Zinc CEO Arun Misra. The purpose of the company is clear: more renewables, greater efficiency, and cleaner-burning fuels.
Progress in Emissions
The impact has already begun to be felt. Hindustan Zinc cut greenhouse gas emissions by 14% since 2020. It’s cutting its carbon footprint by decarbonizing its operations, powering up on more renewable energy, and electrifying. These steps align with world sustainability targets as well as India’s vision of cleaner industries.
Why This Matters
Hindustan Zinc is the second-largest integrated zinc producer in the world and third-largest silver producer. Its energy needs are massive, but this deal shows a shift to clean power. Using up to 530 MW of green electricity reduces reliance on fossil fuels. It also sets an example for other heavy industries.
Key Highlights
- Green Power Supply: Up to 530 MW from Serentica Renewables, up from 450 MW.
- Renewable Share: Over 70% of total power needs now renewable.
- Uninterrupted Supply: Guarantees 315 MW every 15-minute time block.
- Emissions Reduction: 14% drop in greenhouse gas intensity since 2020.
- Net Zero Goal: Targeting net zero by 2050 or sooner.
This partnership highlights India’s growing renewable energy sector. Serentica, known for round-the-clock green power, is a key player. For Hindustan Zinc, the transaction is consistent with its climate objectives without sacrificing continuity of operations. It’s a win for the world and for the company.
Challenges and Opportunities
It is not easy to scale up renewable projects. Land, funds, and technology integration are challenges. But the gain—lower emissions, savings, and a greener reputation—is huge.Hindustan Zinc’s moves could inspire other industries to follow suit.
This deal marks a milestone. With up to 530 MW of green power, Hindustan Zinc is powering up its future—and the planet’s.
