Largest Pumped-Storage Power Stations 2026
Pumped storage is the world's main form of grid-scale electricity storage: water is pumped uphill when power is cheap and released through turbines when it is expensive. These stations consume more electricity than they return, so they are counted as storage rather than as generation.
