From Coal to Fusion: Repowering the Bull Run Plant in Tennessee

September 26, 2025

A New Chapter for America’s Energy Future

🌍 Coal stacks down. Atomic fusion up.

A new chapter has begun at the retired Bull Run coal plant in Tennessee.

The Tennessee Valley Authority (TVA) and Type One Energy are preparing to build the world’s first commercial fusion prototype on this former coal site — transforming one of America’s worst polluting plants into the bedrock for future clean energy abundance.

🚀 Infinity One, their stellarator prototype, is planned for 2026. If successful, it will lead to Infinity Two — delivering 350 MW of round-the-clock carbon-free, base load electrical generation in the 2030s.

The Promise of Fusion

Nuclear fusion is the holy grail of energy production. It’s what powers the sun.

When we crack it, we have clean energy for billions of years. It produces no greenhouse gases, would have less long-lived radioactive waste than nuclear fission, and cannot “melt down” as there is no self-sustaining chain reaction or long-lived residual heat.

Revitalising Communities Through Innovation

This isn’t just about new technology. It’s about revitalising communities — $223.5M in investment and 330 new jobs created where coal once defined livelihoods in Oak Ridge, Tennessee.

🌍 Repowering means more than replacing energy sources. It means preserving what matters — the people, the grid, the future — while cutting carbon.

It means forging ahead using all of our innovative spirit and resources.

Coal infrastructure: a bridge from the energy of fossils to the energy of the stars.
