AI & Data Center Power Demand
Tech companies are betting on SMRs — nuclear is the only baseload answer to hyperscale AI power demand
AI & Nuclear Demand
Tech company nuclear PPAs, SMR agreements, and reactor restart deals
Google signed the world's first corporate nuclear energy deal with Kairos Power for multiple 50 MW fluoride salt-cooled high-temperature reactors. Target deployment starting 2030, full capacity by 2035.
Oracle announced plans to power a planned AI data center campus with three small modular reactors. Target capacity of 462 MW. Project pending NuScale NRC design certification outcomes.
Meta signed an agreement with Oklo for 150 MW of nuclear power from Aurora microreactors starting in the early 2030s. Contingent on NRC licensing approval for Oklo's design.
Google expanded nuclear power procurement with Constellation, adding approximately 1,000 MW from existing fleet nuclear assets to power Google Cloud regions in the Midwest.
Amazon Web Services inked a deal with Dominion Energy for nuclear power from North Anna Power Station to support Virginia data center operations. One of the largest nuclear PPAs ever signed.
Microsoft signed a 20-year PPA with Constellation to restart TMI Unit 1. The 835 MW reactor will power Microsoft data centers after a $1.6B refurbishment. Regulatory approvals ongoing.
Microsoft invested $678M in Helion Energy and agreed to purchase power from Helion's first commercial fusion plant targeting 2028. A landmark corporate fusion bet — 50 MW initial capacity.
