“Castellano coordinated the network connection design and underground reticulation for a 14-lot subdivision in the South-West. They staged the energisation to match our releases and kept the Endeavour Energy process moving so we never lost time on the program.”

Trusted on Sydney developments
“For our 22-unit project they managed the supply design, metering room provisions and individual metering coordination, and flagged the substation requirement early. Having one ASP run both the temporary site supply and the permanent connection made the build far simpler.”
“We needed a high-capacity connection with CT metering for a new industrial unit. They confirmed the available supply, handled the application and got us energised in time for the tenant fit-out. Exactly the kind of contractor you want on a commercial program.”
“Across multiple builds they’ve handled our temporary builders supply and the permanent connections to AS/NZS 3012. Reliable, compliant and easy to deal with — we use them as our go-to Level 2 ASP in the north-west growth area.”
