Key Takeaways
- • Hyperscalers Alphabet, Amazon, Meta and Microsoft have signed nuclear PPAs that could supply about 6.9 GW by the early 2030s, according to a Carnegie Endowment paper published June 2, 2026.
- • Announced hyperscaler nuclear agreements could provide up to 13 GW in total, split roughly equally between PPAs and direct partnerships with reactor developers.
- • Big tech's preference is to act as energy offtaker rather than nuclear owner or project developer, a posture the paper attributes to priorities, timing and cost considerations.
- • Meta's 20-year PPA with Constellation for 1,121 MW from the Clinton Clean Energy Center kept a plant slated for 2027 shutdown running, and Meta's separate 2.6 GW Vistra PPA is contingent on NRC approval.
- • The paper flags reputational exposure, nonproliferation concerns and long-term waste management as entanglement risks hyperscalers must confront.
Summary
A Carnegie Endowment for International Peace paper by John Pendleton and Mackenzie Schuessler, published June 2, 2026, examines how large U.S. technology companies are approaching nuclear power to meet electricity demand driven by AI data centers. The authors note that the United States hosts the world's largest data center market and that hyperscalers require firm, always-available power that already strains grids facing capacity, reliability and affordability challenges.
Hyperscalers are pursuing nuclear through two main pathways: power purchase agreements with existing or planned plants, and direct partnerships with startups developing small and advanced reactors. The paper characterizes the latter as largely venture-capital-style moves, with opaque terms that give hyperscalers a stake in future options. Deal structures range from straightforward PPAs with large utilities to speculative, long-term arrangements with developers, and some are behind-the-meter while others connect to transmission grids. Fusion is also being monitored as a potential option that could enter the mix by the mid-2030s.
In PPAs, the paper reports that Alphabet, Amazon, Meta and Microsoft together could provide about 6.9 GW by the early 2030s. Alphabet, Kairos Power and the Tennessee Valley Authority agreed that TVA will buy up to 50 MW from Kairos's Hermes-2 molten-salt reactor, expected to operate in 2030; the paper calls this the first U.S. utility PPA featuring a Generation IV reactor. It also describes a Google-Kairos program targeting 500 MW by 2035. Amazon and Talen Energy's 2025 agreement, after FERC declined a behind-the-meter proposal in November 2024, moved to a front-of-the-meter configuration providing access to 1.9 GW through 2042, with full volume expected by 2032. Meta's 20-year Constellation PPA for 1,121 MW from the Clinton plant is structured as a purchase of clean energy credits, with power still sold to the regional market, and it required no state or federal approval. Meta also announced a 20-year Vistra PPA in January 2026 covering 2.6 GW from Ohio and Pennsylvania plants, contingent on NRC approval, with financial terms undisclosed.
The paper frames these cautious approaches as reflecting risk tradeoffs in a historically regulated, slow-moving sector, and says it is still unclear whether big tech will commit large capital to nuclear beyond offtake arrangements.
