The Largest Hydroelectric Dams by Capacity

Hydroelectric dams ranked by installed generating capacity in megawatts, with height, river and completion year. The top 50 total 224 GW.

How this is ranked: Installed capacity is the maximum nameplate output, not actual annual generation — a dam in a seasonal monsoon basin may produce far less of its rating than one on a steady-flow river. The two measures diverge widely.
