The Tennessee Valley Authority (TVA), the largest utility in the US, has issued a letter of intent to US-based Type One Energy regarding potential deployment of the company’s 350-MW Infinity Two stellarator fusion power plant at the site of TVA’s retired coal-fired Bull Run plant near Oak Ridge, Tennessee.

Type One Energy said the Infinity Two design is as a first-generation baseload fusion plant that uses stellarator technology, which has demonstrated stable and steady-state operation.
