Big Tech AI nuclear commitments and data center power demand
Key Questions
What major nuclear power purchase agreements have Big Tech companies signed recently?
Hyperscalers have signed multiple large deals including Meta's 6.6 GW Vistra PPA for eight Natrium reactors, Microsoft's 800 MW 20-year PPA with Constellation, Google's $2B data center with a 50 MW Kairos Power SMR, and Walmart's first nuclear PPA with Constellation for 176 MW.
How much electricity demand are data centers projected to create by 2030?
Data center power demand is projected to reach 945 TWh by 2030, creating a timing mismatch with new nuclear capacity coming online.
Which microreactors achieved criticality by the July 4 deadline?
Four microreactors from Antares, Valar, Deployable, and Aalo reached criticality, including Aalo's 10-MWe Aalo-X built in eight months and Valar's Ward 250 that powered an Nvidia desktop live on stage.
What partnerships exist between nuclear developers and AI companies?
Valar Atomics partnered with Nvidia to develop a 30 MW waterless AI factory in Utah, while X-energy is assessing Xe-100 deployment with Talen Energy in PJM and SGE announced a 4.2 GW UK BWRX-300 fleet with Google Cloud.
What government funding supports new nuclear reactor deployments?
The DOE announced a $17.5B loan program for 10 AP1000 reactors, and Anthropic signed a $19B data center lease amid rising power needs.
What regulatory or policy pushback is emerging against data centers?
Florida SB 484 bans utility cost pass-through to residential customers, Detroit is drafting data center regulations, and rural backlash surveys plus Oregon rate hikes highlight growing concerns over electricity costs.
How are flexible loads affecting nuclear PPA incentives?
Data center pricing economics show flexible loads can avoid peak costs, which may weaken the economic case for nuclear PPAs despite rising demand.
What international nuclear commitments were announced in the UK?
A Polish billionaire committed £35B for 14 BWRX-300 reactors in the UK alongside SGE's 4.2 GW fleet announcement with Google Cloud.
Hyperscalers deepening SMR/utility deals: Meta 6.6 GW Vistra PPA, eight Natrium reactors; Microsoft-Constellation 800 MW 20-year PPA; Google $2B data center with 50 MW Kairos Power SMR PPA; Walmart first nuclear PPA with Constellation for 176 MW. Four microreactors (Antares, Valar, Deployable, Aalo) reached criticality by July 4 deadline, with Aalo's 10-MWe Aalo-X built in 8 months and Valar's Ward 250 powering an Nvidia desktop live on stage. Valar Atomics partners with Nvidia to develop 30 MW waterless AI factory in Utah. X-energy partners with Talen Energy to assess Xe-100 deployment in PJM. SGE announces 4.2GW UK BWRX-300 fleet with Google Cloud. Polish billionaire commits £35B for 14 BWRX-300s in UK. DOE $17.5B loan program for 10 AP1000 reactors. Anthropic signs $19B data center lease. Data center power demand projected at 945 TWh by 2030, highlighting timing mismatch between AI demand and new nuclear capacity. Counter-narrative: Florida SB 484 bans utility cost pass-through to residential customers; data center pricing economics show flexible loads can dodge peak costs, potentially weakening nuclear PPA incentives; Detroit drafting data center regulations; rural backlash survey; Oregon rate hikes.
