Google has announced a groundbreaking power purchase agreement (PPA) with Commonwealth Fusion Systems (CFS), marking the largest-ever direct corporate offtake deal for fusion energy. The agreement is coupled with a new investment in CFS, aimed at accelerating the development of fusion power and supporting the company’s efforts to bring it to the grid at scale.
Fusion energy, often dubbed the “Holy Grail” of clean power, involves merging two atoms to release massive amounts of energy without carbon emissions or long-lived radioactive waste. Despite its promise, achieving net-energy positive fusion has remained a major scientific and engineering challenge due to the extreme conditions required.
CFS, spun out of MIT in 2018, is leading efforts to make fusion a practical energy source. In partnership with MIT’s Plasma Science and Fusion Center, CFS is building SPARC, a demonstration fusion device using a tokamak design that employs high-temperature superconducting magnets to confine plasma. SPARC is expected to validate the feasibility of net-positive fusion, paving the way for ARC — the company’s first commercial fusion plant.

ARC, to be developed in Chesterfield, Virginia, is anticipated to be the world’s first grid-scale fusion power facility, with operations targeted for the early 2030s. Under the PPA, Google will purchase power from ARC once it comes online.
Bob Mumgaard, CEO of CFS, called the deal a “strategic milestone,” emphasizing fusion’s potential to deliver abundant and clean energy to fuel global economic growth. Google’s latest investment follows its participation in CFS’s $1.8 billion raise in 2021.
Michael Terrell, Google’s Head of Advanced Energy, noted the company’s excitement to support CFS’s efforts, describing the partnership as a long-term bet on a transformative technology that could meet the world’s future energy needs.
