Marsden Park Data Centre
Under ConstructionPlanned
CDC-owned Sydney campus under construction at Marsden Park. The approved development reports 504 MW; an October 2026 modification proposal seeks 743.5 MW. Neither figure establishes operational load. Building configuration and power basis require reconciliation.

| Claim / measurement | Scope and status | As of | Evidence and accounting |
|---|---|---|---|
| 504 MW IT load | Whole Marsden Park campus announced in 2024 Planned · cumulative | 2024-10-25 | Reported claim ↗ Excluded from capacity totals. Announcement date; operator explicitly calls this ICT capacity. Not commissioned load. |
| 504 MW Facility power | Approved SSD-70889211 campus Planned · cumulative | 2025-11-27 | Conflicting claim ↗ Excluded from capacity totals. Planning determination date; portal calls this power consumption. Relationship to operator ICT figure unresolved. |
| 720 MW Grid connection | Substation associated with SSD-70889211 Planned · unclear | 2025-11-27 | Reported claim ↗ Excluded from capacity totals. Determination date; reported substation capacity, not IT load or proof of energized connection. |
| >504 MW Unspecified power | Marsden Park campus planned capacity Planned · cumulative | 2026-10-09 | Conflicting claim ↗ Excluded from capacity totals. Retrieval date of undated operator page; says over 504 MW, unlike the exact approved figure. |
| ≈1000 MW Unspecified power | Potential ultimate Marsden Park campus scalability Planned · cumulative | 2026-10-09 | Reported claim ↗ Excluded from capacity totals. Retrieval date; one gigawatt converted to MW. Scalability towards this figure is an aspiration, not approved or operational capacity. |
| 743.5 MW Unspecified power | Proposed modified whole-campus capacity Planned · cumulative | 2026-10-09 | Reported claim ↗ Excluded from capacity totals. Retrieval date of October 2026 update; application being prepared. Replaces proposed total of 504 MW rather than adding 743.5 MW; approval not established. |
| 5 MW Unspecified power | Initial facility approved under DA-24-00542 Planned · unclear | 2024-11-14 | Reported claim ↗ Excluded from capacity totals. Local approval date; inclusion within or overlap with SSD campus capacity is unresolved. Do not add to campus totals. |
