The Tennessee Valley Authority (TVA) is a feerally owned corporation in the United States created by congressional charter in May 1933 to provide navigation, flood control, electricity generation, fertilizer manufacturing, and economic development in the Tennessee Valley, a region particularly impacted by the Great Depression. The TVA was envisioned not only as an electricity provider, but also as a regional economic development agency that would use federal experts and electricity to rapidly modernize the region's economy and society.
