The Tennessee Valley Authority (TVA) is a corporate agency of the United States that provides electricity for business customers and local power distributors serving more than 10 million people in parts of seven southeastern states. TVA receives no taxpayer funding, deriving virtually all of its revenues from sales of electricity. The TVA was created in 1933 to help combat the Great Depression, and today it is the largest public power provider in the United States.
