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 & development

Under construction250 MW

Power for servers, GPUs, storage & networking (IT power) · Source as of 2026-06-30

NEXTDC reports 250 MW in progress at 30 June 2026 under its defined in-progress measure. Multiplex broke ground on 17 March 2026; FY26 material also describes early structural works. This does not mean all 250 MW has completed mechanical/electrical fit-out, and the builder's mid-2027 target is not a verified whole-capacity commissioning date.

Government certification

Certification not verified

No verified certification scope has been assigned to this record. Unknown does not mean uncertified.

Scope and context

Horsley Park. FY26 discloses 365 MW total; the facility page's older 350 MW headline is superseded for the numeric split. Separate planning applications are not added as extra sites or capacity.
Technical details reported by Data Center Map are shown separately from the Atlas's primary-source observations.
Primary builder gives the address as 16 Johnston Crescent, Horsley Park. No exact coordinates have been inferred from the address.
City map markers are approximate. No exact facility coordinates have been verified.

Compute, workloads & commercial commitments

Site-specific workloads, GPU inventory and customer contracts are not established by the cited evidence. Electrical capacity and AI-ready specifications alone do not establish these details.

These disclosures describe the operator’s portfolio. They are not assigned to this facility or included in its power totals.

Facility specificationAustraliaReported observation

NEXTDC Australian fitted-out capacity: 277.9 MW

NEXTDC reports 287.9 MW consolidated built capacity at 30 June 2026, including 10 MW at Kuala Lumpur. The derived Australian portfolio is 277.9 MW. Named-site evidence allocates 273.45 MW within this portfolio.

Australian fitted-out capacity: 277.9 MW IT

Evidence scope: Operator portfolio · NEXTDC
Evidence as-of date: 2026-06-30

How to read this: Built capacity is the designed power of fitted-out halls. Customer infrastructure may require further investment. The regional table rounds Australia to 278 MW. Named-site capacity is deducted before the remaining portfolio balance is counted.
