Watch the history of pumped storage hydropower in the United States
Pumped storage plants for hydroelectric power in the United States were primarily built between 1960 and 1990. There have been no new projects since 2012, but three new ones have been proposed, potentially adding 2.6 GW to the existing 22 GW capacity. The largest facility is the Bath County Pumped Storage Station in Virginia, with 2.9 GW.
