Lots of developments on both tracts:
1. Confirmed 2nd primary substation on the left tract, making the total confirmed 3.
2. Data Center rows are visible on the right of PS1.
3. Visible bulk substation transformer on the most right pad, possibly a transformer on one of the pads at PS1.
4. Mass grading on the left tract, indicating further development of the site towards adjecent parcels on the north and west.
5. Utility substation expansion now connected to the main switch, suspected POI for IREN's energization in Q2.
6. Suspected further build-out of primary substations on the left tract, south of the first two, confirmed by drone footage posted by a subcontractor.
My considerations:
-> IREN is making a site that is a blank slate for mass production of data center shells.
-> The area right of PS1 is showing indications of rows, underground conduits, and this area will soon be ready for data center construction.
-> The fact that there is 1 bulk substation transformer visible on the most right transformer pad, makes me certain that energization is not far out.
-> I expect 750MW of gross power at the 36.5kV level (DC ready), to be flowing by the end of the year (incremental over the course of the year).
-> Based on the concentration of the substations on the left tract (possibly 3 or 4), we could see the entire 1,400MW become operational on these 2 tracts.
-> This further strengthens the believe that this will be a VR200/VR300 site, with a much smaller data center footprint due to a massive jump in rack density.
Now as to "wen deal":
I think
@IREN_Ltd is making a site that can still pivot in either direction of Build-to-suit, colocation, or AI Cloud/IaaS.
By doing all the step-down work first, but preparing multiple data center areas down to the 34.5kV level — the ultimate use-case doesn't need to be set in stone yet.
I think this site will have a slow ramp up, but when the use-case is determined, all the moving parts will be in place, and the construction will be "released" as a coil spring into mass data center development, on multiple areas across the site in parallel.
Time to data center = Time to revenue
There are no delays when you do all the pre-work for 1,400MW of data centers, making the eventual construction a simplified copy-paste task at an unprecedented scale and pace.
Sweetwater is the flagship and will be the holy grail of AI infrastructure in 2027/2028.
Patience is a virtue, take the time to learn and know what you own.
