Serentica Increases Renewable Energy Capacity For Hindustan Zinc to 530 MW

Indian renewable energy company Serentica Renewables has announced strengthening its partnership with Hindustan Zinc Limited, India’s largest and the world’s second-largest integrated zinc producer. This expanded power delivery agreement increases Hindustan Zinc’s round-the-clock (RTC) renewable energy capacity from 450 MW to 530 MW.

This has led to a boost in its clean energy share to over 70% of total power consumption. This agreement is the first-of-its-kind Time Block-based round-the-clock renewable energy contract, ensuring a guaranteed supply of at least 315 MW in every 15-minute time block. The project will integrate newly developed solar, wind, and energy storage facilities across multiple locations in India while leveraging existing renewable assets.

Developed under a captive structure, the project will be spread across high-resource locations in India and is expected to be fully operational by 2027. This innovative hybrid solution eliminates Hindustan Zinc’s reliance on conventional power sources by delivering seamless, reliable energy through advanced storage systems and market-driven mechanisms.

Akshay Hiranandani, CEO of Serentica Renewables, added, “This agreement is a breakthrough in providing uninterrupted, firm renewable energy to one of India’s largest industrial players. By guaranteeing 315 MW in every 15-minute time block, we’re solving the intermittency challenge and ensuring that Hindustan Zinc has a stable, reliable power supply for its operations.”

Speaking on the development, Arun Misra, CEO – Hindustan Zinc Limited, said, “Sustainability at Hindustan Zinc is about future-proofing our business and driving long-term value through innovation. As the world transitions to a low-carbon economy, we embrace our dual role as a leader in this transformation and as an active participant with our critical metals like zinc & silver. This agreement marks a significant step in our climate action strategy. By securing 70% of our power from renewables, we are targeting nearly 70% reduction in carbon emissions, setting sights on our goal of achieving net zero by 2050 or sooner.”

This agreement marks a shift in industrial power procurement, moving beyond traditional round-the-clock (RTC) models to an advanced Time Block-Based Firm Renewable Energy solution. Unlike conventional renewable energy contracts, this agreement ensures precisely scheduled and dispatchable power using a combination of solar, wind, and cutting-edge energy storage technologies.
