Delectrik Systems Secures 120MWh Vanadium Flow Battery Contract in India, Advancing Long-Duration Energy Storage
Date: 27 Oct 2026 |
Major six-hour energy storage project in Gujarat highlights growing demand for vanadium flow battery (VFB) technology and renewable energy integration.
27 October 2026 — Delectrik Systems, an Indian developer and manufacturer of vanadium flow battery (VFB) technology, has secured a major 20MW/120MWh long-duration energy storage contract in Gujarat, India, marking another significant milestone in the commercialization of VFB technology.
The project was awarded through a competitive tender conducted by Gujarat Industries Power Company Limited (GIPCL), a public-sector power generation company. Delectrik will partner with Bondada Engineering to deliver the six-hour energy storage system at GIPCL's existing natural gas power plant in Vadodara.
The project has been approved by Gujarat Urja Vikas Nigam Limited (GUVNL), the state's principal electricity buyer, as a pilot initiative to demonstrate the potential of VFB technology in enhancing grid flexibility and supporting renewable energy integration.
Advancing Long-Duration Energy Storage
The 120MWh VFB installation will leverage existing transmission infrastructure at the Vadodara facility, with necessary upgrades, to provide reliable and flexible energy storage.
Designed for approximately 1.5 charge-discharge cycles per day, the system will help demonstrate how long-duration storage can support electricity demand management and the integration of renewable energy into India's power grid.
Unlike conventional lithium-ion batteries, vanadium flow batteries offer several advantages for stationary energy storage, including:
- Long-duration storage: Delivering six hours of energy storage to support grid flexibility and renewable energy integration.
- Enhanced safety: Avoiding the thermal runaway risks associated with lithium-ion batteries.
- Long operational life: Supporting thousands of charge-discharge cycles with minimal degradation.
- Scalability: Allowing energy storage capacity to be expanded through larger electrolyte tanks.
- Potential lifetime cost benefits: Offering opportunities for lower total ownership costs over extended operating periods.
Building Momentum in India's VFB Market
The Gujarat contract follows Delectrik Systems' earlier success in securing a 16.7MW/100MWh VFB project with Bondada Engineering through a tender issued by NTPC, India's largest power company, in June 2026.
That project is planned for the Khavda Renewable Energy Park in Gujarat, one of India's largest renewable energy developments.
Delectrik also previously deployed a 3MWh VFB pilot system for NTPC, which has reportedly operated successfully since its installation was completed in mid-2025.
Together, the two major project awards represent 220MWh of planned VFB energy storage capacity, demonstrating increasing interest in long-duration battery technology across India's electricity sector.
Supporting India's Clean Energy Transition
India's rapid expansion of renewable energy is creating growing demand for energy storage solutions capable of delivering electricity over longer periods.
“The market is now demanding longer duration storage. Even in India, where it started with 2-hour, 4-hour, now that the penetration of renewable energy is increasing, the market really needs these 6-hours+ of storage,” said Vishal Mittal, founder and CEO of Delectrik Systems, in an earlier interview with Energy-Storage.news.
Mittal also described the Gujarat project as a model for future installations designed to deliver firm, dispatchable renewable energy around the clock.
With India's projected energy storage requirements reaching approximately 74GW/411GWh by 2031–2032, VFB technology is emerging as a potential solution alongside lithium-ion batteries and pumped hydro storage.
The latest contract represents another important step toward the wider adoption of vanadium flow batteries and reinforces their potential role in building a more reliable, flexible, and sustainable energy system.
