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.

Solar production and public green space remain options; coal ash questions remain

CLAXTON — Tennessee Valley Authority will demolish most structures at Bull Run Fossil Plant but has not yet shared plans for the ultimate disposition or reuse of the property.

Bull Run Fossil Plant was a coal-fired plant in the Claxton community, located just outside of Oak Ridge in Anderson County, Tenn. The plant opened in 1967. TVA closed it in 2023, and plans to phase out all its coal fired plants by 203.

The utility and its spokesman Scott Brooks have listed the scrubbers, coal handling structures and the large chimney, nicknamed the “lighthouse” by locals, as structures that will likely come down.

TVA has listed some possibilities for the site, including battery storage, park areas, “economic development” and a synchronous condenser, which is a device meant to keep the overall grid's power supply stable without generating any power of its own. This last option would involve keeping and repurposing the turbine building. TVA has not committed to any of these ideas.

TVA retires coal-fired plant; just four more to go

OAK RIDGE — The Tennessee Valley Authority took another step toward its goal to phase out all its coal plants by 2035.

TVA officially announced Bull Run Fossil Plant, at 1265 Edgemoor Road in Anderson County’s Claxton community, closed on Friday, Dec. 1. The TVA board decided to close the plant four years earlier on Feb. 14, 2019. Now the utility says it plans to retire all of its coal plants by 2035. The utility has cited the environment and efficiency as reasons for closing the plants. TVA plans to create solar and natural gas plants to replace the power formerly generated by coal. TVA has not made final plans for the Bull Run site.

“It’s not an easy decision to retire a plant, but it’s one we must make to secure a reliable and cleaner energy future as our generation portfolio and load shapes change,” Jacinda Woodward, senior vice president of power operations, said in a press release.

TVA solicits public input following release of environmental assessment for Bull Run Fossil Plant decommission

CLAXTON — Tennessee Valley Authority plans to close its Bull Run Fossil Plant (BRF) in Anderson County, but it’s still looking for public input on what comes next.

“As a large, inflexible coal unit with medium operating costs and a high forced outage rate, BRF does not fit current and likely future portfolio needs,” the federal utility said in a draft Environmental Assessment.

TVA is looking at three different options for the future of the structures still standing on the site by the Clinch River near Oak Ridge: taking down all structures; taking down some of them; or leaving everything standing. A recent report lays out the environmental consequences of each of these actions. The report, in draft form, is against that third choice, listing it as only an option for the sake of comparison.

“If the facility is left in the “as-is” condition, it likely would present a higher risk than Alternatives A or B for the potential to contaminate soil and groundwater as systems and structures degrade. As such, this alternative is not a reasonable alternative,” the draft states.

TVA stated its considering removing “all or most of the buildings and structures” on a 250-acre area. After closing the plant, but before any demolitions, TVA will begin by removing components that may be used at other TVA sites, draining of oil and fluids from equipment, taking ash out of the boilers, removing information technology assets, removing plant records and other tasks.

The Bull Run Environmental Assessment is 170 pages long and available for public review. It doesn’t directly tackle the coal ash storage conundrum that has grabbed the attention of politicians, nearby residents and environmental activists, because that issue involves separate regulations.
