A self-contained transformer kiosk designed and built by ABB Australia, resolved a challenge mid-way through Horizon Power’s port upgrade project at Exmouth, on the tip of the North West Cape, 1270km from Perth.
The West Australian regional electricity supplier had anticipated a costing of $40K for the civil works associated with a transformer pad and oil separation facility but received a quotation of $240K from its power station sub-contractor.
With time pressures, a remote location and a heated economy, the options to obtain alternative contractors did not prove fruitful.
ABB Australia developed a solution that has left the hard ground untouched, since bunding is enclosed within a self-contained kiosk.
The 15 tonne, 3.5 MVA kiosk was designed and manufactured at ABB Australia’s Osborne Park facility and shipped to site, as separate units.
The design was a first for ABB Australia and Horizon Power and has potential for other sites, especially as it was constructed for cyclonic conditions.
Horizon Power’s building schedule continued to plan, and Exmouth’s new 7 MW power station completed its 60 day trial in April 2007.
