The U.S. electricity market is mainly comprised of electric co-operatives, municipal systems and shareholder-owned electric utilities, with the latter accounting for a market share of more than 68 percent. While U.S. electric utilities generated around 2.5 petawatt hours of electricity, total end use consumption of electricity amounted to about 3.9 petawatt hours in 2010. That year, the utility industry produced revenue of around 370.5 billion U.S. dollars.

Prior to the 2012 merger of Progress Energy and Duke, Southern Company was the largest utility, based on market value. The company also ranks among the five investor-owned utilities with the highest customer satisfaction in the United States.
