Vanadium Redox Flow Battery (3 MWHr VRFB) Storage at NETRA
Brief
Brief
NTPC has setup Vanadium Redox Flow Battery (VRFB) system of 600 kW / 3 MWh, marking the country’s first MWh-scale flow battery deployment. This project is a major milestone toward long-duration energy storage (LDES) and supports NTPC’s vision of transforming NETRA into a Green Energy Campus, enabling large-scale renewable integration and self-reliant energy innovation.

Electrolyte: Vanadium in different oxidation states (V2+, V3+, VO2+, VO2+)
Salient Strength
Salient Strength
- De-coupling of ‘Power’ & ‘Energy’:Independence in Scaleup,
- Long Lifetime:>20,000 cycles
- Cyclic degradation: almost nil
- Low Fire / Explosion Risk:Aqueous electrolyte, so no thermal runaway
- Recyclability: >99%, Significantly more compared to Li-ion,
- High Depth of Discharge (DoD): ~95% DoD, unlike ~80% in BESS.
