132kV substation build, hyperscale data centre
Rosehill, NSW
A 132kV connection where the energisation dates are set by the network, not by us.
Nebula holds the full electrical scope for a 132kV substation programme and the construction of a four-bay switchyard, serving a hyperscale data centre operator at Rosehill.
Work at this voltage is only half the difficulty. The programme runs against energisation dates fixed by the network and by the facility behind it, so cabling, primary plant, protection and SCADA all have to arrive at the same hold points together. Self-performing the scope is what makes that possible: the crews installing the switchgear are the crews commissioning the protection on it.
What the scope covered
- Primary and secondary 132kV and 11kV cabling
- 132kV disconnectors and MV switchgear
- Neutral earthing transformers
- SCADA and protection cabinets, built in full
- Circuit breaker timing, partial discharge and VLF high potential testing
Four bays, built and proven by the same team.
