The Tennessee Valley Authority (TVA) is a federally owned corporation in the United States created by congressional charter on May 18, 1933, to provide navigation, flood control, electricity generation, fertilizer manufacturing, and economic development to the Tennessee Valley, a region particularly affected by the Great Depression. Senator George W. Norris (R-Nebraska) was a strong sponsor of this project. TVA was envisioned not only as a provider, but also as a regional economic development agency that would use federal experts and rural electrification to help modernize the rural region's economy and society.
