Electricity generation by electric utilities in the U.S. 2004-2024

Electric utilities in the United States generated approximately 2,241 terawatt-hours of electricity in 2024, with a slight decrease 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 a decrease in electricity generation in the past decade, electric utilities account 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 2023. Meanwhile, electricity generation by independent producers grew by almost 20 percent in the past decade, amounting to roughly 1,850 terawatt-hours that same year.

Leading electric utilities in the U.S.

Constellation Energy Generation stands out in the U.S. electricity market as the leading utility by net output, with over 200 terawatt hours generated in 2023. That same year, Duke Energy was the leading utility in the U.S., based on revenue. Nevertheless, when it comes to market value, it was the Florida-based NextEra Energy to rank as the country's most valuable electric utility, at roughly 156 billion U.S. dollars in 2024.
