|---|---|---|---|
| 150 MW IT load | Ultimate M4 target IT capacity Planned · cumulative | 2026-10-09 | Reported claim ↗ Excluded from capacity totals. As-of is retrieval date of undated live facility page; target, not commissioned capacity. Relationship to 162 MW announcement unresolved. |
| 162 MW Unspecified power | M4 digital infrastructure campus Planned · cumulative | 2026-01-19 | Reported claim ↗ Excluded from capacity totals. As-of is announcement date. Source does not identify IT, facility or grid basis; do not combine with 150 MW IT target. |
