Core-field coverage counts eight basic fields available in the Atlas. It is not an accuracy score or a measure of technical specification completeness. Individual evidence checks appear below.

Evidence by field

Evidence status applies to the named field and cited sources. “Not found” means those sources do not establish the fact; it does not establish absence.

Capacity Source checked: Electrical basis is verified as critical equipment capacity. The 36 MW rating of each building is not a verified fully fitted IT subtotal.Checked 2026-09-22 · STACK Infrastructure ↗ · STACK Infrastructure ↗ · A.G. Coombs ↗

Capacity & development

Operating / built36 MW

Power for servers, GPUs, storage & networking (IT power) · Source as of 2023-08-22

MEL01A is a 36 MW critical-capacity building delivered in 2023. The contractor reports staged hall fit-out continuing alongside live operations in June 2025. The fully fitted IT subtotal is not disclosed, so the 36 MW design rating remains outside the operating subtotal.

Excluded from capacity totals: scope or power basis is not comparable.

MEL01B construction completion was reported in November 2025. Its 36 MW critical design capacity is separate from MEL01A; completion of all IT fit-out and operational availability is not established.

Excluded from capacity totals: scope or power basis is not comparable.

Scope and context

Truganina campus. MEL01A, B, C and D remain within one physical-site record. Marketing campus power and the 2023 completion announcement require phase reconciliation before MW aggregation.
Only the first MEL01A 36 MW delivery is quantified here; later campus plans and buildings cannot be added as delivered capacity.
MEL01A and MEL01B are separately completed 36 MW buildings, together 72 MW critical design capacity. Commissioned hall capacity has not been separated from completed shells and staged fit-out. The later 180 MW campus plan also includes MEL01C and MEL01D.
STACK defines critical capacity at the server data-hall boundary. The separate 135 MW utility substation is not equipment capacity.

Compute, workloads & commercial commitments

Facility specificationAustraliaReported observation

STACK MEL01 campus: disclosed development boundary

Four building design values are 36, 36, 54 and 54 MW. This envelope includes the completed first facility.

Disclosed campus specification: 180 MW unspecified electrical boundary

Evidence scope: Named facility · STACK Infrastructure
Evidence as-of date: Applicable date not stated

How to read this: This observation has its own electrical and physical boundary. It is not an additional contribution to the comparable IT subtotal, a GPU count or a delivery forecast. Four building design values are 36, 36, 54 and 54 MW. This envelope includes the completed first facility.

Facility specificationAustraliaOperating deployment

STACK delivered its first Melbourne 36 MW building

Operator confirms first-phase 36 MW delivery on 22 August 2023; the second phase remained upcoming.

First building delivered capacity: 36 MW, boundary unspecified

Evidence scope: Named facility · STACK Infrastructure
Evidence as-of date: 2023-08-22

How to read this: Electrical basis is not stated. This is nested inside the campus and duplicates the profile stage observation, so is not an additional sum. The then-72 MW or later 180 MW campus specification is not a delivered total.
