Pumped Storage Hydropower — India's Water Batteries
Pumped storage hydropower is a water battery: a plant pumps water up to a higher reservoir when power is surplus and lets it fall back through turbines when demand peaks. It is in the news because a PIB backgrounder of 19 October 2026 set out India's build-out: 7.43 GW running, 15.87 GW under way and 105.56 GW planned by 2035-36.
