The agency brief
What this U.S. agency structure tells us
The Tennessee Valley Authority (TVA) is a wholly owned Government corporation created by the TVA Act of 1933. Authority is vested in a nine-member Board of Directors appointed by the President and confirmed by the Senate, while day-to-day operations are led by the President and Chief Executive Officer. Structurally, TVA is distinctive among federal entities because it combines public power generation, river system management, and regional economic development within a single, financially self-supporting organization. Its divisional structure aligns around major mission areas such as power generation and operations, nuclear oversight, finance, external relations, and independent oversight through the Office of Inspector General. TVA’s mission directly serves citizens through reliable electricity, flood control, navigation, environmental stewardship, and economic development across a seven-state region.
