New Albany, Ohio campus targeting 1 GW, with nuclear supply agreements signed in January 2026.
What is established
Partially operational. 1 GW announced (basis not stated by the source); expected Jun 2027; owned or developed by Meta; power source: Nuclear PPAs + grid.
What is not disclosed
Accelerator count, hardware platform, project capex, named tenant, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
Nuclear agreements with TerraPower, Oklo and Vistra are power-purchase commitments, not on-site reactors delivering today. UPDATE 2026-08-01: Epoch lists Prometheus operational at an estimated 631 MW IT (854 MW projected by Q4 2026) against the ~1 GW announced cluster scale. Status moved to partially operational; the 1 GW figure remains the announced nameplate. Not operator-confirmed capacity, so nothing enters the confirmed column.
Corroborated by more than one source, but not yet backed by physical evidence.
Power readiness
Capacity basis unclear
A megawatt figure exists but the source does not say whether it is IT load, site power or generation.
Derived from the evidence on this page by a published rule, not a model. How this is calculated.
