Enhanced-Pumped-Storage: Combining pumped-storage in a yearly storage …
This option does not involve pumped-storage, however, it can be used to increase the storage capacity of the watershed just by simply building more dams with storage reservoirs upstream of the river. In this way, the watershed will be able to store more water during the wet period and generate more energy during the dry period.
How Does Closed-Loop Pumped Hydro Storage Measure Up?
There are 40 PSH plants and 152 generators scattered nationwide. A 2022 GIS-based analysis by the NREL found technical potential for 35 terawatt-hours (TWh) of energy storage at 14,846 sites across the U.S., Alaska, Hawaii, and Puerto Rico. Those sites could add 3.5 TW of capacity, assuming a 10-hour storage duration.
