NTPC commissions 3 MWh vanadium flow battery system

Union Power Minister Manohar Lal has inaugurated NTPC’s 3 MWh vanadium redox flow battery project. The system has been developed through NTPC’s in-house research and development programme and commissioned at the NTPC Energy Technology Research Alliance in Greater Noida, Uttar Pradesh. The project advances India’s long-duration storage capability and supports better integration of renewable power into the grid.

The vanadium redox flow battery uses vanadium ions in different oxidation states to store energy for extended periods. This makes it useful for managing the variability of solar and wind generation. The technology offers long cycle life, non-flammable operation, and the ability to scale power and energy capacity independently.

The commissioning of this indigenous system broadens India’s access to alternative storage materials and reduces reliance on lithium and rare earth imports. NTPC views the project as a step towards expanding domestic expertise in long-duration storage and strengthening grid stability as renewable capacity continues to rise.
