Tennessee Valley Authority

Background

In the late 19th century, the Army Corps of Engineers first recognized several potential dam sites along the Tennessee River for electricity generation and navigation improvements. The National Defense Act of 1916, signed into law by President Woodrow Wilson, authorized construction of a hydroelectric dam on the Tennessee River in Muscle Shoals, Alabama, for the purpose of producing nitrates for ammunition; that dam was completed in 1924. During the 1920s and the 1930s, Americans began to support the idea of public ownership of utilities, particularly hydroelectric power facilities. Many believed privately owned power companies were charging too much for power, did not employ fair operating practices, and were subject to abuse by their owners–utility holding companies–at the expense of consumers. [ citation needed ] The concept of government-owned generation facilities selling to publicly owned distribution utilities was controversial, and remains so today. The private-sector practice of forming utility holding companies resulted in them controlling 94% of generation by 1921, and they were essentially unregulated. In an effort to change this, Congress and Roosevelt enacted the Public Utility Holding Company Act of 1935 (PUHCA). During his 1932 presidential campaign, Franklin D. Roosevelt expressed his belief that private utilities had "selfish purposes" and said, "Never shall the federal government part with its sovereignty or with its control of its power resources while I'm President of the United States."

U.S. Senator George W. Norris of Nebraska also distrusted private utility companies, and in 1920 blocked a proposal from industrialist Henry Ford to build a private dam and create a utility to modernize the Tennessee Valley. In 1930, Norris sponsored the Muscle Shoals Bill, which would have built a federal dam in the valley, but it was vetoed by President Herbert Hoover, who believed it to be socialistic. The idea behind the Muscle Shoals project became a core part of President Roosevelt's New Deal program that created the Tennessee Valley Authority.

Even by Depression standards, the Tennessee Valley was in dire economic straits in 1933. 30% of the population was affected by malaria. The average income in the rural areas was $639 per year (equivalent to $12,260 in 2024), with some families surviving on as little as $100 per year (equivalent to $1,919 in 2024). Much of the land had been exhausted by poor farming practices, and the soil was eroded and depleted. Crop yields had fallen, reducing farm incomes. The best timber had been cut, and 10% of forests were lost to fires each year.

Founding and early history

President Franklin D. Roosevelt signed the Tennessee Valley Authority Act (ch. 32, Pub. L. 73–17, 48 Stat. 58, enacted May 18, 1933, codified as amended at 16 U.S.C. § 831, et seq.), creating the TVA. The agency was initially tasked with modernizing the region, using experts and electricity to combat human and economic problems. TVA developed fertilizers, and taught farmers ways to improve crop yields. In addition, it helped replant forests, control forest fires, and improve habitats for fish and wildlife.

The authority hired many of the area's unemployed for a variety of jobs: they conducted conservation, economic development, and social programs. For instance, a library service was instituted for this area. The professional staff at headquarters were generally composed of experts from outside the region. By 1934, TVA employed more than 9,000 people. The workers were classified by the usual racial and gender lines of the region, which limited opportunities for minorities and women. TVA hired few African Americans, generally restricted for janitorial or other low-level positions. TVA recognized labor unions; its skilled and semi-skilled blue collar employees were unionized, a breakthrough in an area known for corporations hostile to miners' and textile workers' unions. Women were excluded from construction work. With the goal of providing further economic relief to TVA employees, Knoxville TVA Employees Credit Union was formed. In 1934, Knoxville TVA Employees Credit Union established a place for TVA employees to store their money when the Great Depression shuttered many traditional banks.

Many local landowners were suspicious of government agencies, but TVA successfully introduced new agricultural methods into traditional farming communities by blending in and finding local champions. Tennessee farmers often rejected advice from TVA officials, so the officials had to find leaders in the communities and convince them that crop rotation and the judicious application of fertilizers could restore soil fertility. Once they had convinced the leaders, the rest followed.

TVA immediately embarked on the construction of several hydroelectric dams, with the first, Norris Dam in upper East Tennessee, breaking ground on October 1, 1933. These facilities, designed with the intent of also controlling floods, greatly improved the lives of farmers and rural residents, making their lives easier and farms in the Tennessee Valley more productive. They also provided new employment opportunities to the poverty-stricken regions in the Valley. At the same time, however, they required the displacement of more than 125,000 valley residents or roughly 15,000 families, as well as some cemeteries and small towns, which caused some to oppose the projects, especially in rural areas. The projects also inundated several Native American archaeological sites, and graves were reinterred at new locations, along with new tombstones.

The available electricity attracted new industries to the region, including textile mills, providing desperately needed jobs, many of which were filled by women. A few regions of the Tennessee Valley did not receive electricity until the late 1940s and early 1950s, however. TVA was one of the first federal hydropower agencies, and was quickly hailed as a success. While most of the nation's major hydropower systems are federally managed today, other attempts to create similar regional corporate agencies have failed. The most notable was the proposed Columbia Valley Authority for the Columbia River in the Pacific Northwest, which was modeled on the TVA, but did not gain approval.

World War II

To provide electricity for essential industries during World War II, TVA engaged in one of the largest hydropower construction programs ever undertaken in the U.S. This was especially important for the energy-intensive aluminum industry, which was used in airplanes and munitions. By early 1942, when the effort reached its peak, 12 hydroelectric plants and one coal-fired steam plant were under construction at the same time, and design and construction employment reached 28,000. In its first 11 years, TVA constructed 16 hydroelectric dams. During the war, the agency also provided 60% of the elemental phosphorus used in munitions, produced maps of approximately 500,000 square miles (1,300,000 km 2 ) of foreign territory using aerial reconnaissance, and provided mobile housing for war workers.

The largest project of this period was the Fontana Dam. After negotiations led by then-Vice President Harry Truman, TVA purchased the land from Nantahala Power and Light, a wholly owned subsidiary of Alcoa, and built Fontana Dam. Also in 1942, TVA's first coal-fired plant, the 267-megawatt Watts Bar Steam Plant, began operation. The government originally intended the electricity generated from Fontana to be used by Alcoa factories for the war effort. However, the abundance of TVA power was a major factors in the U.S. Army's decision to locate uranium enrichment facilities in Oak Ridge, Tennessee, for the world's first atomic bombs. This was part of an effort codenamed the Manhattan Project.

Increasing power demand

By the end of World War II, TVA had completed a 650-mile (1,050 km) navigation channel the length of the Tennessee River and had become the nation's largest electricity supplier. Even so, the demand for electricity was outstripping TVA's capacity to produce power from hydroelectric dams, and so TVA began constructing additional coal-fired plants. Political interference kept TVA from securing additional federal appropriations to do so, so it sought the authority to issue bonds. Several of TVA's coal-fired plants, including Johnsonville, Widows Creek, Shawnee, Kingston, Gallatin, and John Sevier, began operations in the 1950s. In 1955, coal surpassed hydroelectricity as TVA's top generating source. On August 6, 1959, President Dwight D. Eisenhower signed into law an amendment to the TVA act, making the agency self-financing. During the 1950s, TVA's generating capacity nearly quadrupled.

The 1960s were years of further unprecedented economic growth in the Tennessee Valley. Capacity growth during this time slowed, but ultimately increased 56% between 1960 and 1970. To handle a projected future increase in electrical consumption, TVA began constructing 500 kilovolt (kV) transmission lines, the first of which was placed into service on May 15, 1965. Electric rates were among the nation's lowest during this time and stayed low as TVA brought larger, more efficient generating units into service. Plants completed during this time included Paradise, Bull Run, and Nickajack Dam. Expecting the valley's electric power needs to continue to surge, TVA began building nuclear power plants in 1966. The following year, TVA began work on Tellico Dam, which was initially conceived in the 1930s and later became its most controversial project.

Financial problems, Tellico Dam, and restructuring

During the 1970s, significant changes occurred in the economy of the Tennessee Valley and the nation, prompted by energy crises in 1973 and 1979 and accelerating fuel costs throughout the decade. The average cost of electricity in the Tennessee Valley increased fivefold from the early 1970s to the early 1980s. TVA's first nuclear reactor, Browns Ferry Unit 1, began commercial operation on August 1, 1974. Between 1970 and 1974, TVA set out to construct 17 nuclear reactors, based on projections of continued rapid power demand increases. However, in the 1980s, it became increasingly evident that the agency had vastly overestimated the valley's future energy needs, and rapid construction cost inflation and new regulations following the Three Mile Island accident posed additional obstacles to this undertaking. In 1981, the board voted to defer the Phipps Bend plant, as well as to slow construction on all other projects. The Hartsville and Yellow Creek plants were cancelled in 1984 and Bellefonte in 1988. Citing safety concerns, all of TVA's five operating nuclear reactors were indefinitely shut down in 1985 with the two at Sequoyah coming back online three years later and Browns Ferry's three reactors coming back online in 1991, 1995, and 2007.

Construction of Tellico Dam raised political and environmental concerns, as laws had changed since early development in the valley. Scientists and other researchers had become more aware of the massive environmental effects of the dams and new lakes, and worried about preserving habitats and species. The Tellico Dam project was initially delayed because of concern over the snail darter, a small ray-finned fish which was discovered in the Little Tennessee River in 1973 and listed as an endangered species two years later. A lawsuit was filed under the Endangered Species Act and the U.S. Supreme Court ruled in favor of protecting the snail darter in Tennessee Valley Authority v. Hill in 1978. The project's main motive was to support recreational and tourism development, unlike earlier dams constructed by TVA. Land acquired by eminent domain for the Tellico Dam and its reservoir that encountered minimal inundation was sold to private developers for construction of present-day Tellico Village, a planned retirement community.

The inflation crises of the 1970s and early 1980s, combined with cancellation of several planned nuclear plants, put the agency in deep financial trouble. In an effort to restructure and improve efficiency and financial stability, TVA began shifting towards a more corporate environment in the later 1980s. Marvin Travis Runyon, a former corporate executive in the automotive industry, became chairman of the TVA in January 1988, and pledged to stabilize the agency financially. During his four-year term he worked to reduce management layers, and cut overhead costs by more than 30%. This required laying off thousands of workers and transferring many operations to private contractors. These moves resulted in cumulative savings and efficiency improvements of $1.8 billion (equivalent to $3.6 billion in 2024 ). His tenure also saw three of the agency's five nuclear reactors return to service, and a rate freeze that lasted 10 years.

Early 1990s to late 2010s

As the electric-utility industry moved toward restructuring and deregulation, TVA began preparing for competition. It cut operating costs by nearly $800 million a year, reduced its workforce by more than half, increased the generating capacity of its plants, and developed a plan to meet the energy needs of the Tennessee Valley through 2020.

In 1992, work resumed on Watts Bar Unit 1, and the reactor began operation in May 1996. This was the last commercial nuclear reactor in the United States completed in the 20th century. In 2002, TVA began work to restart Browns Ferry Unit 1, the last of TVA's reactors mothballed in 1985. This unit returned to service in 2007. In 2004, TVA implemented recommendations from the Reservoir Operations Study (ROS) on how it operates the Tennessee River system. In 2005, the company announced its intention to construct an Advanced Pressurized Water Reactor at its Bellefonte site in Alabama, filing the necessary applications in November 2007. This proposal was gradually trimmed over the following years, and essentially voided by 2016. In October 2007, construction resumed on Watts Bar Unit 2. which began commercial operation in October 2016. Watts Bar Unit 2 was the first new nuclear reactor to enter service in the United States in the 21st century.

On December 22, 2008, an earthen dike impounding a coal ash pond at TVA's Kingston Fossil Plant failed, releasing 1.1 billion US gallons (4,200,000 m 3 ) of coal ash slurry across 300 acres (1.2 km 2 ) of land and into two tributaries of the Tennessee River. The spill, of which cleanup was completed in 2015 at a cost of more than $1 billion, was the largest industrial spill in United States history, and considered one of the worst environmental disasters of all time. A 2009 report by engineering firm AECOM found that multiple inadequate design factors of the ash pond were responsible for the spill, and in August 2012, TVA was found liable for the disaster by the U.S. District Court for the Eastern District of Tennessee. The initial spill resulted in no injuries or deaths, but several employees of an engineering firm hired by TVA to clean up the spill developed illnesses, some of which were fatal. In November 2018, a federal jury ruled that the contractor did not properly inform the workers about the dangers of exposure to coal ash and failed to provide them with necessary personal protective equipment.

In 2009, to gain more access to sustainable green energy, TVA signed 20-year power purchase agreements with Maryland-based CVP Renewable Energy Co. and Chicago-based Invenergy Wind LLC for electricity generated by wind farms. In April 2011, TVA reached an agreement with the Environmental Protection Agency (EPA), four state governments, and three environmental groups to drastically reduce pollution and carbon emissions. Under the terms of the agreement, TVA was required to retire at least 18 of its 59 coal-fired units by the end of 2018, and install scrubbers in several others or convert them to make them cleaner, at a cost of $25 billion, by 2021. As a result, TVA closed several of its coal-fired power plants in the 2010s, converting some to natural gas. These include John Sevier in 2012, Shawnee Unit 10 in 2014, Widows Creek in 2015, Colbert in 2016, Johnsonville and Paradise Units 1 and 2 in 2017, Allen in 2018, and Paradise Unit 3 in 2020.

Recent history

In 2018, TVA opened a new cybersecurity center in its downtown Chattanooga office complex. More than 20 information technology specialists monitor emails, social media, and network activity for cybersecurity and grid security threats. Across TVA's digital platform, two billion activities occur each day. The center is staffed 24 hours a day to spot any threats to TVA's transmission grid.

Given continued economic pressure on the coal industry, the TVA board defied President Donald Trump and voted in February 2019 to close two aging coal plants, Paradise Unit 3 and Bull Run. TVA chief executive Bill Johnson said the decision was not about coal, per se, but rather "about keeping rates as low as feasible". They stated that decommissioning the two plants would reduce its carbon output by about 4.4% annually. TVA announced in April 2021 plans to completely phase out coal power by 2035. The following month, the board voted to consider replacing almost all of their operating coal facilities with combined-cycle gas plants. Such plants considered for gas plant redevelopment include the Cumberland, Gallatin, Shawnee, and Kingston facilities.

In early February 2020, TVA awarded an outside company, Framatome, several multi-million-dollar contracts for work across the company's nuclear reactor fleet. This includes fuel for the Browns Ferry Nuclear Plant, fuel handling equipment upgrades across the fleet, and steam generator replacements at the Watts Bar Nuclear Plant. Framatome provided its ATRIUM 11 fuel for the three boiling water reactors at Browns Ferry. This contract makes TVA the third U.S. utility to switch to the ATRIUM 11 fuel design. On August 3, 2020, President Trump fired the TVA chairman and another board member, saying they were overpaid and had outsourced 200 high-tech jobs. The move came after U.S. Tech Workers, a nonprofit that works to limit visas given to foreign technology workers, criticized the TVA for laying off its own workers and replacing them with contractors using foreign workers with H-1B visas.

Citing its aspiration to reach net-zero carbon emissions in 2050, the TVA Board voted to approve an advanced approach of nuclear energy technology with an estimated $200 million investment, known as the New Nuclear Program (NNP) in February 2022. This would promote the construction of new nuclear power facilities, particularly small modular reactors, with the first facility being constructed in partnership with Oak Ridge National Laboratory at the Clinch River Nuclear Site in Oak Ridge. In December 2025, the United States Department of Energy allocated TVA a grant of $400 million to assist in deployment of advanced light-water SMRs; TVA is planning to build a BWRX-300 SMR.

On December 23, 2022, TVA had several hours of rolling blackouts due to the late December 2022 North American winter storm. As many as 24,000 Nashville Electric Service customers were without power, with thousands more from smaller distributors affected as well.
