Energy shift creates opening for ‘world’s largest batteries’


              Eric Gustad, community affairs manager for Consumers Energy, looks into the upper reservoir of the Ludington Pumped Storage Plant on Jan. 31, 2022. The facility near Ludington, Mich., generates electricity by pumping water from Lake Michigan to the upper reservoir atop a bluff, then releasing it through giant turbines as needed. Advocates of pumped storage call such facilities the "world's largest batteries." (AP Photo/John Flesher)

            There are 43 'Pumped Storage Plants' in the U.S., accounting for 95% of the nation's utility-scale energy storage.
