Our Network

Our primary role at SA Power Networks is building, extending, maintaining and upgrading the South Australian electricity distribution network - a strategic community asset that is a core component of the State's infrastructure.

We deliver electricity from the transmission network and directly-connected generators (primarily renewable) to around 850,000 residential and business customers.

The network has a route length of around 88,000 kilometres, which includes 400 zone substations, more than 73,000 transformers and 720,000 Stobie poles.
