Connecting Your Substation Into The Network
Building or upgrading a substation is only half the job. Before it can supply power, it needs to be formally connected into the Ausgrid or Endeavour Energy network. That covers lodging a network connection application, working through the distributor's design review, coordinating construction and testing, and finally energisation, the point where the substation is switched on and goes live. Backed by our Level 2 ASP accreditation and a team completing Level 1 ASP accreditation, we manage that whole connection process for you, whether the physical substation was built by us or by another contractor.

Getting your substation connected doesn't need to be complicated. Here's what developers, strata managers and businesses most often ask before we start. If you only need power temporarily disconnected or reconnected rather than a new connection, our disconnect and reconnect services cover that instead.
Substation connection is the process of formally linking a new or upgraded substation into the Ausgrid or Endeavour Energy network so it can supply power. It covers the network connection application, distributor design approval, construction coordination, testing and energisation.
No. Substation installation is the physical construction of the chamber, kiosk or pad mount substation. Substation connection is the separate process of getting that substation approved and switched on by the network operator. Many projects need both, and we can manage them together.
Developers and builders on subdivision or estate projects, strata schemes upgrading shared infrastructure, and commercial or industrial clients bringing a new substation online.
Timeframes depend on the distributor's application queue and design review. Application and approval are usually the biggest factor, so we recommend engaging us early in the project.
Yes. We can manage the connection process for a substation you or another contractor has built, or handle the connection alongside our own installation as one job.
Site details, the substation design or specification and your intended timeframe. From there we confirm scope during a site assessment before pricing is locked in.
Cost depends on the distributor, the substation size and site conditions. Every job starts with a site assessment before we confirm scope and provide a fixed quote.
