Electricity generation by electric utilities in the U.S. 2004-2022

Electric utilities in the United States generated approximately 2,237 terawatt-hours of electricity in 2022, with a slight increase in comparison to the previous year. Overall, electricity generation from U.S. utilities has slowly decreased over the past decades, from over 2,500 terawatt-hours in 2004.

Electricity providers in the U.S.

Despite the decrease in electricity generation recorded in the past decade, electric utilities still accounted for the majority of net electricity generation in the U.S. However, their margin has been slowly reducing, reaching a little over half of the net output in 2022. Meanwhile, electricity generation by independent producers grew by almost 20 percent in the past decade, surpassing 1,850 terawatt-hours that same year.

Leading electric utilities in the U.S.

Exelon stands out in the U.S. electricity market as the leading utility by net output, with over 200 terawatt hours generated in 2021. That same year, the company was also, by a wide margin, the leading utility in the U.S., based on revenue. Nevertheless, when it comes to market value, the Chicago-based utility did not make the top five in the country in the first months of 2022. At that time, Florida-based NextEra Energy was by far the country's most valuable electric utility, at roughly 145 billion U.S. dollars.
