# Meta Nuclear Supercluster

Meta's 6.6 GW nuclear power portfolio announced January 9, 2026, comprising agreements with three nuclear suppliers to power AI datacenters. Meta internally refers to this as their nuclear "supercluster" for AI infrastructure.

## Portfolio Structure

**Total capacity:** 6.6 GW across three technologies

**Suppliers:**
1. **TerraPower (Natrium):** Up to 8 Natrium sodium-cooled fast reactors
   - Committed: 2 units (690 MW firm, up to 1 GW dispatchable) by 2032
   - Options: 6 additional units (2.1 GW) by 2035
   - Each unit: 345 MW baseload + molten salt storage surge to 500 MW for 5.5 hours

2. **Vistra:** Power from existing nuclear fleet (extensions/restarts)

3. **Oklo:** Microreactor commitments (sub-30 MW units)

## Strategic Rationale

Meta explicitly cited the need for "firm, dispatchable, 24/7 carbon-free power" for AI training workloads. The company specifically highlighted Natrium's surge capability (345 to 500 MW) as matching AI training cycle variability—the first public statement linking advanced reactor load-following to AI compute demand patterns.

The three-technology portfolio reflects different deployment timelines: Vistra's existing fleet provides immediate capacity, TerraPower's Natrium targets 2032-2035, and Oklo's microreactors fill intermediate gaps starting 2028+.

## Significance

This represents the largest single corporate nuclear power commitment in history, exceeding all prior corporate clean energy PPAs in scale. Meta's framing of nuclear plants as "AI infrastructure" rather than clean energy credits marks a narrative shift in how hyperscalers position nuclear procurement.

## Timeline

- **2026-01-09** — Announced 6.6 GW nuclear portfolio across TerraPower, Vistra, and Oklo
- **2032** — Target delivery for first 2 Natrium units (690 MW firm)
- **2035** — Target delivery for up to 6 additional Natrium units (2.1 GW)
