Roadmap & milestones

First commercial fusion licence issued anywhere

2026-08-31
Tennessee / Type One Energy — Bull Run, Clinton, TN

Tennessee issued the first licence anywhere for a commercial fusion machine on 31 Aug 2026, presented by Governor Bill Lee at the Organization of Agreement States meeting in Nashville. It covers Project Infinity, Type One Energy's 400 MW stellarator plant at TVA's Bull Run Energy Complex in Clinton, and follows the state's first-in-the-nation fusion regulatory framework — built after the NRC delegated fusion regulation to the states. Type One plans to break ground on phase one this year and expects full startup by 2034. A licence is permission to build, not a machine that works: no stellarator has yet produced net energy, and the plant is a decade out.

UK Infinity Fusion Consortium — first private-led UK plant

~ 2026-05
Type One Energy / Tokamak Energy / AECOM

Type One Energy (400 MWe Infinity Two stellarator design), Tokamak Energy (HTS magnets + UK manufacturing) and AECOM (engineering) form a consortium to develop the UK's first private-sector-led fusion power plant, building on the US Bull Run/TVA project and the government's STEP programme.
