About This Dataset
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.
Analysis
Fengning in China is the largest at 3,600 MW, 1.20 times the 3,003 MW of Bath County. The 5 stations here total 13,623 MW. 3 of them are in China, and 2 countries are represented in total. The smallest on the chart, Ludington, is rated at 2,172 MW, 60% of the leader.
