Bondada
A rare non-lithium award — flow batteries decouple power from energy, making them well-suited to the many-hour storage lithium handles less economically.
Mercom India ↗What it means
Most Indian storage tenders assume lithium-ion; a vanadium redox flow award is a deliberate step toward long-duration alternatives. Flow batteries separate the power stack from the electrolyte tanks, so adding hours of storage is comparatively cheap — the opposite of lithium’s economics. It complements the lithium chemistries we compare in our LFP vs NMC guide, and sits within the same NTPC storage push driving India’s central tenders.
The award has been made; the project now moves toward build.
