The Hyperscaler Nuclear Procurement Rush (2023-2026)
Constellation-Microsoft TMI restart (2023); Google-Kairos first SMR PPA 50→500MW (2025); Meta 6.6GW; Oklo first reactor ~2027
The Hyperscaler Nuclear Procurement Rush
Provenance note: The originally-selected Build.inc URL returned HTTP 404. This file synthesizes corroborating public reports from the discovery-search pass rather than that single article. Distinct from the Meta-6.6GW file — this captures the broader cross-hyperscaler pattern.
Core Pattern
To meet AI data-center load, hyperscalers are procuring nuclear three ways: (1) restart existing plants, (2) first corporate SMR PPAs, (3) multi-GW advanced-reactor development deals.
Anchor Deals
- Constellation ↔ Microsoft (Sep 2023): 20-year PPA to restart Three Mile Island Unit 1 (Pennsylvania).
- Google ↔ Kairos Power (Aug 2025): first corporate SMR PPA; Hermes 2 (Oak Ridge) supplying 50 MW by 2030, scaling to 500 MW.
- Meta ↔ Vistra / Oklo / TerraPower (2026): up to 6.6 GW by 2035 (see meta-66gw-nuclear-deal).
- Oklo: targets first reactor ~2027, ahead of most peers.
Why It Matters
The gating constraint on AI buildout is power; nuclear PPAs are how hyperscalers try to secure firm, carbon-free baseload outside congested grid-interconnect queues. Demand from a single buyer class is now underwriting the SMR/advanced-reactor commercialization curve.
