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.

Status Source checked

Capacity & development

Planned≤ 800 MW

Power basis not established · Source as of 2026-06-03

Up to 800 MW of transmission-connected project power. This is an upstream electricity boundary, not IT load; the separate proposed IT design is up to 600 MW. Energisation from 2028 is a connection target, not delivery of the full campus.

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

IREN ↗Australian Government EPBC Act Public Portal ↗
Planned≤ 600 MW

Power for servers, GPUs, storage & networking (IT power) · Source as of 2026-07-31

Federal referral proposes three halls, each up to 200 MW IT. The 600 MW sum is an ultimate design ceiling; the reviewed records do not establish state development consent, construction or operating supply. It replaces no component already counted at this physical site.

Proposed or approved design capacity. Included in the planning inventory, not a dated delivery forecast or a claim of committed supply.

Government certification

Certification not verified

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

What certification covers →

Scope and context

  • 800 MW headline is not treated as IT load; no construction commencement is stated.
  • Technical details reported by Data Center Map are shown separately from the Atlas's primary-source observations.
  • The federal referral defines a 600 MW IT design ceiling within an 800 MW electricity project. A referral decision is recorded, but no hall has been verified as operating.

Compute, workloads & commercial commitments

Facility specificationAustraliaAnnouncement

Bundey remains an Australian development project

IREN's 800 MW transmission connection supports a proposed campus whose later federal referral specifies up to 600 MW IT across three halls. Neither figure describes a commissioned Australian GPU deployment.

Transmission support ceiling
≤ 800 MW
Evidence as of 2026-08-27
Evidence scope
Named facility · IREN
Evidence as-of date
2026-08-27

How to read this: The 800 MW connection is not IT load. The 600 MW IT value is a proposed design limit in a referral, not a consent, construction start or delivery schedule. IREN's overseas compute contracts do not establish a Bundey offtake.

IREN Bundey campus: disclosed development boundary

An 800 MW electricity connection supports a proposed 600 MW IT campus design across three halls. Energisation from 2028 is a connection target, not delivery of the whole campus.

Electricity connection capacity
≤ 800 MW (grid-connection)
Whole campus connection; proposed envelope
Evidence scope
Named facility · IREN
Evidence as-of date
Applicable date not stated

How to read this: The 800 MW connection and 600 MW proposed IT design have distinct electrical boundaries and are not additive. A federal referral decision is recorded; state development consent and operating halls are not established by the reviewed records. No completion year for the full design is established.

Bundey: 600 MW proposed IT design within an 800 MW electricity project

The federal referral specifies three proposed data halls of up to 200 MW IT each at Bundey, South Australia.

Proposed IT design ceiling
≤ 600 MW IT
Referral dated 31 July 2026
Electricity project ceiling
≤ 800 MW grid/project power
Campus proposal
Evidence scope
Named facility · IREN
Evidence as-of date
2026-07-31

How to read this: The IT and grid figures are different boundaries and are not additive. The IT figure is an upper design limit in a referral; the reviewed records do not establish state development consent, construction or operating capacity. No site-specific GPU deployment or tenant contract is established by the referral.
