India Inaugurates First MWh-Scale Vanadium Redox Flow Battery at NTPC NETRA
Union Minister Manohar Lal inaugurated India's first MWh-scale Vanadium Redox Flow Battery (VRFB) system of 3 MWh capacity at NTPC Energy Technology Research Alliance (NETRA) in Greater Noida on November 11, 2025, with the announcement gaining wider coverage on November 12.
The VRFB uses vanadium ions in liquid electrolytes, enabling long-duration energy storage without degradation — unlike lithium-ion batteries. The technology supports India's goal of reducing lithium import dependence while advancing indigenous long-duration energy storage (LDES) for renewable energy integration and grid resilience. Rajasthan's vast solar capacity makes LDES solutions critical for balancing intermittent solar power output.
