The recent arrival of the Gas Insulated Switchgear (GIS) signified a key milestone on the project.
The six GIS weighing approximately six tonne are located on the first floor of the three storey substation.
Over 120 workers across the various trades are based on this constrained site daily to see the substation through to completion, which is on target for commissioning in September 2013.
The project has involved constructing a new tunnel and four buildings to house the Transpower and Vector substations and will reinforce the power supply into Auckland.
