How Does Closed-Loop Pumped Hydro Storage Measure Up?
According to the EIA, pumped storage hydroelectric systems in the U.S. had 22 gigawatts (GW) of utility-scale nameplate power capacity at the end of 2022—more than any other energy storage resource, including batteries and solar electric with thermal energy storage. There are 40 PSH plants and 152 generators scattered nationwide.
A Comparison of the Environmental Effects of Open-Loop and Closed-Loop ...
Abstract Pumped storage hydropower (PSH) capabilities are generally characterized as either open-loop or closed-loop. The U.S. Department of Energy (DOE) defines open-loop PSH as "continuously connected to a naturally flowing water feature," and closed-loop PSH as "not continuously connected to a naturally flowing water feature."
