Existing Nuclear Power vs. Future Reactors: The AI Power-Contract Timeline
The bounded sample mixes operating-plant purchases with prospective generation, uprates and development rights. A power headline is not, by itself, a common measure of electricity available to an AI load on a given date.

Coverage note
Evidence cutoff: September 22, 2026. This is a five-arrangement sample, not a census of AI power deals. Recovering the saved evidence did not add new collection or experimentation.

How to read this report
- 01Bounded the review to five AI-linked nuclear arrangements announced or materially updated by September 22, 2026: Google–Fortum, Google–Kairos, Meta–Vistra, Meta–Oklo and Meta–TerraPower.
- 02Classified each arrangement by underlying resource status: operating generation, future uprate, construction-stage project, or development-stage advanced reactor.
- 03Separated announced capacity, contractual form, construction or licensing status, and stated delivery timing rather than treating headline capacity as equivalent.
- 04Timeline: Meta’s Prometheus cluster was targeted for 2026; Meta–Vistra purchases start in late 2026; Google–Fortum starts at smaller capacity in 2028 and reaches its stated 50% share in 2030; Hermes 2 is targeted for 2030; Oklo’s first phase is targeted for 2030; TerraPower’s initial units are projected no earlier than 2032; Vistra uprates and Oklo’s full buildout are expected by 2034.
- 05Calculated only disclosed, date-comparable gaps: Oklo’s earliest first phase versus Prometheus’s target is at least four years, and TerraPower’s initial units versus that target are at least six years.
