| Claim / measurement | Scope and status | As of | Evidence and accounting |
|---|---|---|---|
| ≈68 MW IT load | Ultimate KIX1 campus across two buildings Planned · cumulative | 2026-10-09 | Reported claim ↗ Excluded from capacity totals. Operator says up to 68 MW; this is a ceiling, not commissioned capacity. Schema lacks an upper-bound qualifier, so approx is used with this explicit limitation. As-of is retrieval date of undated page. |
| 28 MW IT load | First KIX1 building, identified separately as KIX11 by operator post Planned · incremental | 2026-10-09 | Reported claim ↗ Excluded from capacity totals. Part of the 68 MW campus total, not additional to it. Undated operator page retains mid-2026 planned operation; actual opening is unconfirmed. As-of is retrieval date. |
| 28 MW IT load | First building of KIX1 campus Planned · incremental | 2024-05-23 | Reported claim ↗ Excluded from capacity totals. Announcement-date claim with early-2026 delivery target; overlaps c2 and campus total. |
