Statistical Highlights

EEI maintains comprehensive statistical data on the electric power industry and shareholder-owned electric companies. Below are quick statistical highlights providing an overview of the industry. For more detailed information, see Products and Services.


Forecast Data

  • Total electric industry capability in the United States is forecast by the Energy Information Administration to increase a total of 23.4% from 2012 through 2040.  Coal capability is expected to decrease over 15%, retiring over 50 gigawatts of capability, within the total electric power sector.  Renewable sources increase their capability by almost 35% over the period.
  • Total retail sales are forecast to increase 25.4% from 2012 through 2040.  Those generating electricity for their own use is expected to more than double over the same period. 


  • The U.S. electric power industry's total installed generating capacity was 1,172,604  megawatts (MW) as of December 31, 2012—a 1.0-percent increase from 2011.
  • U.S. investor-owned installed generating capacity was 420,296  MW as of December 31, 2012. This accounts for approximately 36 percent of total electric power industry installed capacity. 
  • Non-utility owned installed generating capacity grew from 487,002  MW in 2011 to 494,684 in 2012.


  • In 2012, total U.S. electricity generation was 4,047,765 gigawatt-hours (GWh)—a 1.3 percent decrease from 2011.
