Google has agreed to purchase power from a planned nuclear fusion plant in the 2030s as it seeks to lock in the massive electricity supplies needed for the boom in data centres and artificial intelligence.

The technology group has committed to buying 200 MW of electricity from Commonwealth Fusion Systems’ (CFS) planned power station in Virginia under a multiyear power purchase agreement, the companies said in a statement.

Google has been an investor in CFS since 2021 and also is increasing its investment stake in the Massachusetts-based company, the statement said.
