Key Takeaways
- Delectrik Systems, working with Bondada Engineering, has won a tender to deploy India's first utility-scale vanadium redox flow battery project, sized at 100 MWh.
- The project was awarded by NTPC Renewable Energy Limited and will be built at Khavda Solar Park, a site planned to reach 30 GW of generation capacity by 2029.
- Deployment is scheduled for 2027 and will mark India's first non-lithium utility-scale battery energy storage system.
- Delectrik Systems said the project will be the first of its scale fully designed, engineered, and manufactured in India.
- The award builds on a smaller 3 MWh flow battery Delectrik Systems deployed for NTPC at Greater Noida in 2025.
Delectrik Systems Wins India's First Utility-Scale Flow Battery Tender
Delectrik Systems, working in collaboration with Bondada Engineering Limited, has won a tender to deploy a 100 MWh vanadium redox flow battery project, the first utility-scale flow battery of its kind in India. The project was awarded by NTPC Renewable Energy Limited, a subsidiary of state-run NTPC Limited.
Inside the Khavda Solar Park Project
The system will be built at Khavda Solar Park, a site in Gujarat planned to grow into the world's largest renewable energy park, with 30 GW of generation capacity targeted by 2029. Delectrik Systems expects to complete deployment in 2027.
A Break From Lithium-Ion Storage
Unlike the lithium-ion batteries that dominate most grid storage projects, vanadium redox flow batteries store energy in liquid electrolyte tanks, an approach suited to long-duration storage. The Khavda project will be India's first utility-scale battery energy storage system built on non-lithium technology.
Delectrik Systems Builds on Earlier NTPC Deployment
Delectrik Systems said the Khavda project will be the first flow battery of this scale fully designed, engineered, and manufactured in India. The award follows a smaller 3 MWh flow battery the company deployed for NTPC at Greater Noida in 2025, which served as a precursor to the larger utility-scale system now planned.
India has largely relied on lithium-ion batteries for grid-scale storage to date, so a 100 MWh non-lithium project marks a shift in the technology mix supporting the country's renewable energy buildout. Vanadium flow batteries are generally valued for their long cycle life and ability to discharge over many hours, characteristics that make them a fit for large solar parks like Khavda that need storage to smooth output across the day.
