TVA Turns 90
Join us in celebrating TVA's 90th anniversary in 2023!
This summer, TVA is offering public tours of some of our dams, allowing you to see inner workings of a dam and learn how we produce clean hydropower while ensuring the health of the waterways.
The TVA Act
Signed in 1933, the Tennessee Valley Authority Act created a public corporation “To improve the navigability and to provide for the flood control of the Tennessee River; to provide for reforestation and the proper use of marginal lands in the Tennessee Valley; to provide for the agricultural and industrial development of said valley...and for other purposes.” Learn more about the TVA Act.
Living our History of Service Every Day
TVA’s original 1933 purpose—set forth in the TVA Act—was to address the Valley's most important issues in energy, environmental stewardship and economic development. Learn about key moments in our history as we’ve tackled important issues in the Tennessee Valley such as power production, flood control and reforestation, and about how our mission of service lives on today. Click on the dates below to get a more thorough accounting of TVA's history from decade to decade.
With the country reeling from the Great Depression, President Roosevelt created his “New Deal” to help America recover. The Tennessee Valley Authority was founded to help the hard-hit Tennessee Valley, where it was tasked with improving the quality of life in the region.
Against the backdrop of World War II, TVA launched one of the largest hydropower construction programs ever undertaken in the United States.
Serving as the nation’s largest electricity supplier, TVA benefited from 1959 legislation that made our power system self-financing.
Accommodating unprecedented economic growth, TVA began building nuclear plants to expand our capacity and spur innovation.
A difficult decade affected by rising fuel costs led to innovative thinking about energy conservation. Working successfully to stop a steady rise in energy costs, we paved the way for a long period of stable rates.
Through a period of restructuring, TVA kept wholesale electric power affordable and reliable while unveiling a new clean-air strategy.
With power demand growing, TVA turned its attention back to clean nuclear energy, returning an idled reactor to service, and paving the way to finish construction of another. We also launched the first green power program in the Southeast.
We continue to carry out our mission of serving the people of the Tennessee Valley region, to make life better through our work in energy, the environment and economic development.
