OperationalUnder Construction

Operational NEXTDC hyperscale colocation facility in Artarmon, Sydney. Stage 1 opened in September 2022 and the builder announced Stage 2 completion in June 2023. Subsequent capacity fit-outs continued: FY26 disclosures report 68MW built and 12MW in progress toward an ultimate 80MW IT capacity at 30 June 2026. S6 at 3 Broadcast Way is a separate facility.

What remains unknown

Current legal property owner; planning records identify NEXTDC Limited as applicant/owner in 2019, but current title was not established.
Exact facility footprint and independently corroborated marker coordinates.
Completion date for the remaining 12MW fit-out after 30 June 2026.
Actual IT demand, facility electricity consumption and grid connection capacity.
Current occupied racks, maximum rack density and contracted versus billing capacity specifically for S3.
Reconciled technical-space and PUE figures across sources.
Site-specific renewable electricity sourcing and sustainability certification scope.
Tenant contracts and tenancy sizes; PeeringDB presence is not proof of tenancy.

Unknown information is deliberately preserved. A sparse profile can still have reliable evidence.

Location detail

PeeringDB facility geocode associated with the operator-confirmed 2 Broadcast Way address; property-marker placement has not been independently corroborated through Google Maps or cadastral evidence.. Coordinate precision: approximate. Street-map detail does not increase the accuracy of the sourced point.

Capacity evidence

Statements retain their dates, definitions and development scope. Do not add these rows together.

Claim / measurement	Scope and status	As of	Evidence and accounting
80 MW IT load	S3 ultimate target IT capacity Planned · cumulative	2026-10-09	Reported claim ↗ Excluded from capacity totals. As-of is retrieval date of an undated operator specification; target capacity is not measured demand or proof of full commissioning.
68 MW IT load	S3 built capacity at FY26 year end Operational · cumulative	2026-06-30	Reported claim ↗ Excluded from capacity totals. FY26 presentation reports built capacity; date is financial year end, corroborated by the results announcement. This overlaps the ultimate 80MW target.
12 MW IT load	S3 remaining capacity fit-out in progress Under Construction · incremental	2026-06-30	Reported claim ↗ Excluded from capacity totals. Announcement explicitly dates capacity in progress to 30 June 2026; this forms part of the ultimate target.
16 MW IT load	S3 capacity delivered during FY26 Operational · incremental	2026-06-30	Reported claim ↗ Excluded from capacity totals. Period addition during FY26, already included in built capacity; not an additional independent facility total.
120 MW Unspecified power	S3 potential electrical capacity described by builder Planned · unclear	2022-08-28	Reported claim ↗ Excluded from capacity totals. Publication-date claim of potential electrical capacity. IT/facility/grid basis is unspecified and cannot be reconciled automatically with the operator's 80MW IT target.
12 MW Unspecified power	S3 opening available capacity Operational · cumulative	2022-11-18	Reported claim ↗ Excluded from capacity totals. Historical opening capacity reported in the dated AGM statement; basis is not explicitly stated in the opening-capacity sentence.
40 MW IT load	S3 Stage 1 fully fitted capacity Planned · cumulative	2022-11-18	Reported claim ↗ Excluded from capacity totals. Historical Stage 1 target reported at the AGM; nested within the overall S3 target and not additive to it.

Disclosed specifications

Technical space

20,000 m²

Operator disclosed target/technical-space figure; builder's 2022 report gives more than 25,000 m² critical IT space, requiring scope reconciliation.

Rack capacity

10,800

Advertised capacity, not installed or occupied rack count.

Cooling

Hot aisle containment; indirect free-cooling CRAC units and modular cooling towers; N+1 independent cooling

Operator also describes N+2 CRAC units per hall and at least 24 hours water storage.

Target PUE

Approximately 1.15 instantaneous / 1.29 annual

Specification footnotes distinguish best instantaneous ratio from annual consumption ratio; facility webpage instead gives 1.2 annual-average target and 1.15 yearly lowest. Not treated as measured current performance.
