History
Early 1900s
DTE's earliest direct corporate ancestor, the Edison Illuminating Company of Detroit, was founded in 1886. By the turn of the century, it split responsibility for commercial electric power in the fast-growing city of Detroit with the Peninsular Electric Light Company; the latter company controlled the city's electric distribution network.
In 1903, the two companies merged as the Detroit Edison Company, which began trading on January 17. That same year, construction began on the Delray 1 Power Plant, and Henry Ford, who had left Edison Illuminating four years earlier, founded Ford Motor Company
