Powell Valley Electric Cooperative purchases energy from the Tennessee Valley Authority (TVA).

The Tennessee Valley Authority is a corporate agency of the United States that provides electricity for business customers and local power companies serving 9 million people in parts of seven southeastern states. TVA receives no taxpayer funding, deriving virtually all of its revenues from sales of electricity. In addition to operating and investing its revenues in its electric system, TVA provides flood control, navigation and land management for the Tennessee River system and assists local power companies and state and local governments with economic development and job creation.
