Power Plant Mall was built in December 2000 on the former site of the 130-megawatt Rockwell Thermal Plant owned by the
Lopez-led
Manila Electric Railroad and Light Company. The thermal power plant, named after the company's first president
James Rockwell, operated between 1950 and December 14, 1973, when it was hit by a fire. In 1994, after protests from Makati residents against its reopening, the plant was decommissioned and subsequently converted by its owners into a modern commercial district. Construction on the shopping mall began in 1998 and was completed and opened on December 26, 2000. Beginning in 2014, Rockwell Land expanded the Power Plant Mall by adding another of additional leasable space, expanding the total retail floor area from with three additional floors, and two VIP cinema theaters. The ground and second levels (R1 & R2) of the expansion opened in December 2017, while Cinemas 7 and 8 at Level R3 opened in January 2018. It is also connected to the luxury condominium development Balmori Suites, replacing the cancelled expansion of Aruga Hotel. ==Brand expansion==
