Overview

  • On June 30, Google signed the industry’s first direct corporate power purchase agreement for 200 MW from CFS’s planned ARC fusion plant in Virginia, targeting grid delivery in the early 2030s.
  • The company also increased its investment in CFS to support development of its SPARC demonstration tokamak and the subsequent ARC reactor.
  • Michael Terrell, Google’s head of advanced energy, said the purchase is intended to send a market signal that fusion can advance from laboratory breakthroughs to commercial scale.
  • Fusion power could provide virtually limitless energy with four times the output per fuel unit of today’s nuclear plants and no long-lived radioactive waste, though major engineering hurdles remain.
  • The agreement aligns with Google’s strategy to secure reliable, carbon-free baseload power for its data centers as AI-driven energy demand grows.
