• GreenSquare is proposing MEL1 at 44–76 Simcock Avenue in Spotswood with up to 240MW of stated IT capacity
  • The campus has a 220kV power design, while GreenSquare says the project is still moving through planning and network assessment

The fact

GreenSquare is planning a 240MW data-centre campus in Spotswood, Melbourne, aimed at cloud and AI workloads. Known as MEL1, the proposed development would be built at 44–76 Simcock Avenue. The design includes a 220kV power connection, with GreenSquare targeting a PUE below 1.24 and water usage effectiveness of about 0.1. It plans to use closed-loop hybrid cooling, which the company says can operate without water for most of the year.

GreenSquare plans to pay for the grid connection and the infrastructure needed to bring power to the site. The network still needs to confirm that it can supply enough capacity. MEL1 remains in planning, and GreenSquare has not said how large the first phase will be or when power could first be delivered.

The assessment

Power delivery is the clearest constraint between MEL1's proposed scale and operating capacity. GreenSquare has identified a 220kV design and says it will fund the project's grid connection, but the network still has to establish that sufficient capacity can be supplied. That distinction matters because the 240MW figure describes the proposed campus at full scale.

GreenSquare has not publicly identified how much IT capacity would be delivered in the first phase or when that capacity could be energised. A connection design therefore does not yet establish a delivery schedule. For BTW readers, the next step is a defined first phase tied to confirmed network capacity and a commissioning date. That would show how GreenSquare intends to turn the 240MW campus design into operating infrastructure.

What to watch

Watch for the planning decision, the confirmed grid-connection scope and GreenSquare's first construction phase. A phase-specific IT load, available connection capacity and energisation date would show how much of the proposed 240MW can move into construction and when the first capacity could become operational.
