Fusion research, natural gas, solar power and battery improvements at heart of TVA’s plans to wean itself off coal
OAK RIDGE — The Tennessee Valley Authority is phasing out coal and announcing developments tied to other energy sources at two plants that sit on either side of Oak Ridge.
One of the options includes a fusion test site. Scientists have long pursued fusion energy, though the technology remains in infancy and has yet to generate electricity anywhere.
The TVA coal plant on Edgemoor Road in the Claxton community in Anderson County closed Dec. 1 last year. TVA remains uncommitted to any plans for most of the land around the plant. A company recently announced, however, that it plans tests connected to fusion power in a small part of one of Bull Run’s old buildings by 2028. It will be an experiment and not generate power directly.
Meanwhile, TVA plans to retire Kingston Fossil Plant on Swan Pond Road in Harriman by the end of 2027. Its nine coal-fired units power about 818,000 homes. To replace the power generated at the plant, TVA plans to build a new complex at the Kingston plant’s site, combining natural gas, solar power and battery storage.
TVA plans to retire all its coal plants by the 2030s.

News Sentinel: Playground near TVA’s Bull Run Fossil Plant contaminated by coal ash
Testing by independent Duke University researchers indicates a playground in the Claxton community contains dangerous levels of coal-ash byproducts.
The playground is near the Tennessee Valley Authority’s Bull Run steam plant, which has historically used vast amounts of coal to produce electricity and stored the resultant coal ash in huge landfills near the facility on Melton Hill reservoir near Oak Ridge. The plant will be decommissioned within two years, but questions remain about how TVA will handle the tons of remnant coal ash produced over the lifetime of the plant.
Duke University researchers sampled soil from the site, and results showed high levels of heavy metals and other toxins typically present in coal ash.
TVA maintains its testing has not detected harmful levels of contaminants in the area, but the News Sentinel’s Jamie Satterfield, who was been relentless in her investigations of TVA coal-ash policies and the disastrous Kingston coal slurry spill of 2008, noted that “There are no human health guidelines, however, for substances like coal ash that combine many toxins or radioactive metals.”
