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 more than 800,000 residential and business customers.

The network has a route length of around 88,000 kilometres, which includes 408 zone substations, more than 74,000 transformers and over 718,000 Stobie poles.

Major projects

Whether it's an updated substation meeting growth in local demand or supplying our biggest mining projects, SA Power Networks plays an important role in supporting the achievement of our economic, community and social objectives.

Improving reliability

Each day our dedicated reliability team monitors and analyses power interruptions on our network and implements preventative actions to reduce the risk of future interruptions.
