HV substation design up to 500 kV.

APD Global’s substation team delivers the full scope - primary plant selection and layout, secondary systems, protection, civil and structural, earthing, lightning protection, and 3D design with VR review capability. Nothing is handed off to a subcontractor the client doesn't see.

The team is accredited with Essential Energy, Western Power, Transgrid, ElectraNet, Ausgrid, AusNet, TasNetworks and other Australian network owners. In New Zealand, accreditation extends to Transpower and the distribution networks. New European clients are served from the Rome and Milan offices.

AIS and GIS

Air-insulated and gas-insulated switchgear to 500 kV. APD has delivered zone substations, terminal substations, switching stations and customer substations. Where the site is constrained - urban infill, brownfield industrial, space-limited network - GIS is a first-class offer: the hall, the basement, the frames the plant sits on. GIS substations →

3D design and VR review

Greenfield projects are delivered in 3D with VR review capability - enabling client sign-off of constructability, access, clearances and aesthetics before a sod is turned. The same model feeds construction and O&M documentation.

Owner's engineer and independent engineer

Where the client needs a technical check rather than a design team, APD operates as owner's engineer or independent engineer - reviewing third-party designs, witnessing testing, and providing the independent assurance that lenders, regulators and operators need on high-consequence assets.
