Citywide compressed air energy systems for delivering mechanical power directly via compressed air have been built since 1870. Cities such as , France; , England; , , and , Germany; and , Argentina, installed such systems. Victor Popp constructed the first systems to power clocks by sending a pulse of air every minute to change their pointer arms. They quickly evolved to deliver power to homes and industries. As o. The McIntosh Power Plant was built 30 years ago above a solution-mined salt cavern located 1,500 feet underground, which provides 19.8 million cubic feet of compressed air storage. The plant uses off-peak electricity, or electricity available at times of low demand, to pump air into the cavern.
