History

The Aqueduct post office opened in 1908, and changed its name to Monolith in 1910.
Aqueduct−Monolith began as a camp for workers at a cement plant for the Owens Valley aqueduct project, supplying materials for the construction of concrete structures. William Mulholland bestowed the name change, due to a huge limestone deposit. At Monolith Substation in 2014, Southern [California Edison] commissioned the Tehachapi [Energy Storage Project], which was the largest lithium-ion battery system operating in North America at the time of commissioning and one of the largest in the world.
