Tulsa District, US Army Corps of Engineers Hydropower

Hydropower Nationally

The U.S. Army Corps of Engineers multi-purpose dams are the largest producer of hydropower in the United States, and one of the largest in the world.  The Corps’ hydropower plants provide 100 billion kilowatt-hours annually, enough power to serve more than 10 million households. Operating 353 units at its 75 hydropower plants the Corps dams and reservoirs produce one-fourth of the nation's hydroelectric power.  One of four Power Marketing Administrations in the United States markets the power produced from these plants at average annual revenues of $142 million to the U.S. Treasury.

Hydropower Locally

Tulsa District operates and maintains 8 hydroelectric power plants, containing a total of 22 units with a generating capacity of 584 megawatts.  Seven of the plants are located within eastern Oklahoma with one located just across the border in Texas.  These plants benefit approximately 2 million end users throughout Oklahoma, Texas, Arkansas, Missouri, Kansas and Louisiana.
