The roots of Duke Energy goes back to the Catawba Power Company, founded in the year 1900 by Dr. Walker Gill Wylie and his brother. After successfully building and running a hydroelectric power station along the Catawba River near India Hook in South Carolina, the brothers convinced James Buchanan Duke to invest in a newly formed company called the Souther Power Company, and this investment made it possible to carry out the construction of several new hydroelectric plants.

In 1917, several utilities founded or acquired by Duke and his associates were pulled together into the holding company Wateree Power. In 1924, this holding company changed its name to Duke Power, and a few years later most of the subsidiaries were merged into Duke Power.

1973 labour dispute

The 1973 Brookside Strike, a labour dispute between Duke Power and coal mine workers, garnered a lot of attention, and it became the subject of the Academy Award-winning documentary film “Harlan County, USA”.

Mergers and acquisitions

From the late 1990s and onward, Duke Power has made several major mergers and acquisitions, including the merger with the natural gas company PanEnergy that resulted in a name change to Duke Energy.

Duke Energy has acquired or merged with the Midwestern-based Cinergy Corporation, the Canadian gas company Union Gas, the North Carolina-based Progress Energy Inc, and Piedmont Natural Gas.

The 2014 Dan River coal ash spill

In February 2014, the Duke Energy-owned facility Eden in North Carolina spilled 39,000 tons of coal ash into the Dan River. The company eventually pled guilty to criminal negligence (both at Eden and elsewhere) and paid substantial fines. Duke Energy and the U.S. Environmental Protection Agency signed an administrative order for the clean up process.

Getting out of Latin America

In 2016, Duke Energy sold its remaining power operations in Central and South America for 1.2 billion USD.

The 2019 clean-up order

In 2019, the State of North Carolina ordered Duke Energy to remove millions of tons of coal ash from 31 ponds located at six different power plants. The coal ash is mixed with water and stored in uncovered, unlined ponds – and some of it has been sitting there for decades. The clean up is expected to cost 5 billion USD.
