Vedanta Aluminum Metal Issues Corrigendum on Renewable Energy Storage Deal, Updates Battery Storage Capacity
Vedanta Aluminum Metal Limited has issued a regulatory corrigendum to its earlier announcement regarding its renewable energy partnership with Sarnia Renewable India 9 Private Limited (SRI9PL). The company submitted the update to the stock exchanges under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, revising certain technical specifications related to its Battery Energy Storage System (BESS).
The clarification follows the company’s original disclosure dated July 30, 2026, and aims to provide shareholders and regulators with updated information on the integration of battery storage into its renewable power infrastructure.
What Has Changed?
According to the revised filing, Vedanta Aluminum Metal has updated the specifications of the Battery Energy Storage System that will be integrated with its existing solar power arrangement.
Revised Battery Energy Storage System (BESS)
The company has revised the planned Battery Energy Storage System (BESS) capacity to 142.5 MW–150 MW, reflecting updated project specifications.
Higher Assured Renewable Power Supply
The updated agreement also provides for an assured renewable power supply of 90%–95%, enhancing the reliability of electricity delivered under the project.
Integration with Existing 600 MW Solar Agreement
Rather than signing a new power purchase arrangement, the battery storage system will be integrated into Vedanta Aluminum Metal’s existing 600 MW Solar Power Delivery Agreement (PDA) with Sarnia Renewable India 9 Private Limited (SRI9PL).
This allows the company to strengthen its renewable energy infrastructure while leveraging its current long-term solar power agreement.
Why Battery Energy Storage Matters
Battery Energy Storage Systems play a critical role in improving the reliability of renewable energy by storing excess electricity generated during peak solar production and supplying power when generation declines.
For energy-intensive industries such as aluminium manufacturing, integrating BESS offers several benefits:
- Improved stability of renewable power supply.
- Reduced dependence on conventional energy sources.
- Better management of fluctuations in solar generation.
- Enhanced operational efficiency for continuous manufacturing.
- Support for long-term sustainability and decarbonisation goals.
With an assured renewable power availability of up to 95%, the project is expected to strengthen Vedanta Aluminum Metal’s ability to operate its aluminium production facilities using cleaner and more reliable energy.
Company Clarifies Previous Disclosure
Vedanta Aluminum Metal stated that the corrigendum updates the appendix to its earlier regulatory filing dated July 30, 2026. The revised document incorporates the updated Battery Energy Storage System capacity and the assured power supply figures, ensuring greater transparency for investors and regulatory authorities.
The company emphasized that the correction is intended to accurately reflect the technical specifications of the renewable energy project.
What It Means for Investors
The corrigendum does not indicate a change in Vedanta Aluminum Metal’s overall renewable energy strategy. Instead, it provides greater clarity on the technical configuration of the battery storage system supporting its existing solar power agreement.
The integration of large-scale battery storage highlights the company’s continued focus on improving energy efficiency, increasing renewable power utilization, and supporting its broader environmental and sustainability commitments.
