## Company history

Duke Energy traces its origins to Catawba Power Company’s hydroelectric station, which began operating on April 30, 1904. In 1905, James B. Duke and W. Gill Wylie founded Southern Power Company to expand electricity service across the Carolinas. Southern Power supplied hundreds of textile mills and other industries, and changed its name to Duke Power Company in 1924. [25](https://www.duke-energy.com/our-company/about-us/our-history)[26](https://illumination.duke-energy.com/articles/the-idea-that-transformed-the-carolinas)

The company broadened its generation portfolio when Oconee Nuclear Station’s first unit entered commercial operation in 1973. In 1997, Duke Power merged with PanEnergy and adopted the name Duke Energy Corporation. Subsequent combinations expanded the company’s utility operations: it merged with Cinergy in 2006 and Progress Energy in 2012, then completed its acquisition of Piedmont Natural Gas in 2016.
