NEXTDC M3 Melbourne
- Planned critical IT
- 225 MW
- Updated
- Oct 29, 2026
NEXTDC M3 opened in October 2022 in West Footscray, Melbourne, and is expanding toward 225 MW of IT capacity. FY26 results released August 27, 2026 report 60 MW built and 165 MW in progress. Built means fitted-out hall design power, not measured operating IT load. The 42 MW delivered during FY26 must not be added to the built-capacity total. The operator lists 41,000 square metres of technical space, resilient power and cooling, and links to its other Melbourne facilities. M3 is separate from M4 at Port Melbourne.

Power dependency and delay
ForecastOn 21 October 2026, NEXTDC linked M3 expansion delays to Jemena’s 66 kV augmentation works. Based on Jemena’s indicative timetable, it expected the next grid supply increase during FY28, the financial year ending 30 June 2028. Subsequent increases depend on new transformers at Brooklyn Terminal Station; these are forecasts, not secured delivery dates.

Operating scope clarification
ActualOn 28 October 2026, NEXTDC distinguished affected M3 contracts from other existing M3 customer contracts whose capacity was fully commissioned and operational. It excluded the affected contracts’ future contracted earnings from its covenant calculation, while retaining already billed earnings. This does not indicate a campus wide shutdown or quantify operating MW.
SourceFy26 m3 fitout progress context
Reported roundedNEXTDC’s FY26 results, released August 27, 2026, report M3 at approximately 225 MW planned, 60 MW built and 165 MW in progress. Built describes fitted out data hall design power; customer infrastructure may still be required. The FY26 delivery figure must not be added to the reported built capacity total. These figures do not measure occupied, billed or fully energized IT load.

Technical details (6)
Reported context
M3 is near a major electricity substation. Exact service contract, utility counterparty and currently energized grid capacity were not established.
Planned or represented
M3 technical specification describes redundant Piller UPS systems, backing up the site including cooling. No sum of module ratings is treated as campus IT capacity.
Planned or represented
Technical specification describes MTU backup engines with at least 24 hours of on-site fuel storage; this is resilience design, not primary generation supply.
Planned or represented
M3 specification: hot-aisle containment, ceiling-plenum hot return, fan walls and high-efficiency magnetic-bearing chillers, with N+1 independent cooling.
Planned or represented
Technical specification provides at least 24 hours of on-site water storage. It does not establish annual water consumption or a water-rights allocation.
Operational
Opening announcement describes four diverse carrier access points and direct interconnection with NEXTDC M1 and M2. Network providers are not treated as tenants.
