Google will invest in Commonwealth Fusion Systems and buy 200 MW of electricity from its forthcoming power plant.

Although Google won’t have access to the power it’s buying for more than five years, making the purchase now is in Google’s interest. The move both helps CFS on its path to a functioning fusion power generator and gets Google’s foot in the door once CFS meets with success.

Google signs the largest corporate fusion power deal to date, aiming to supply AI-scale energy through its partnership with Commonwealth Fusion Systems.
