Power and Water Corporation has opened its new Darwin Zone Substation to meet the future electricity demands of commercial and residential growth in the Darwin CBD.
The $40 million substation was built to replace the City Zone Substation, which was at the end of its economic life.
The Darwin Zone Substation has 66kV Gas Insulated Switchgear (GIS) housed indoors, as opposed to the existing 66kV outdoor switchyard, which was subject to the harsh Territory environmental elements.
Having the new equipment indoors ensures a protected environment from dust and extreme weather, while reducing noise and providing greater security.
The scope of works included the design and installation of the substation building to house new switchgear and controls and three new power transformers.
The Darwin Zone Substation is the largest in Power and Water’s power system.
