How many states have pumped-storage hydroelectricity?

In 2023, the United States had about 23,167 MW of total pumped-storage hydroelectricity generation capacity in 18 states. The top five states combined were 61% of the national total. Most pumped-storage hydroelectricity systems use more electricity to pump water to upper water storage reservoirs than they produce with stored water.

Do pumped-storage facilities produce electricity?

Therefore, most pumped-storage facilities have net negative annual electricity generation balances. Only a small percentage of the dams in the United States produce electricity. Most dams were constructed for irrigation and flood control and do not have hydroelectricity generators.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) currently accounts for over 90% of storage capacity and stored energy in grid scale applications globally. The current storage volume of PSH stations is at least 9,000 GWh, whereas batteries amount to just 7-8 GWh.

What is the storage capacity of a PSH station?
