Our role

A leader in delivering energy services that customers value.

We’re a key player in South Australia’s energy industry as the state’s sole electricity distributor. Put simply; we build, maintain and upgrade the poles, wires and substations that deliver power to around 850,000 customers.

We also:

  • operate a 24-hour faults and emergencies hotline
  • maintain street lighting for local councils and government
  • take readings of traditional SA Power Networks’ electricity meters.

Our Customer Charter

Our Customer Charter outlines what you can expect from us as well as what we need from you to provide and maintain a safe and reliable power supply.


Our past

With roots in the privately owned Electric Supply Company, the Electricity Trust of South Australia (ETSA) was formed by the State Government in 1946 and was responsible for providing electricity across the state.

In 1996 deregulation of the industry began. The State Government formed ESTA Corporation and electricity assets were separated into general, retail and transmission entities with ETSA Utilities responsible for electricity distribution. In 1999 the electricity industry was privatised and ETSA Utilities was sold to the CK Group.

In September 2012, ETSA Utilities was renamed SA Power Networks to clearly reflect our focus on serving business and residential customers in metropolitan, regional and remote South Australia.

Today, 51% of SA Power Networks is owned by CK Infrastructure Holdings Limited and Power Assets Holdings, which form part of the CK Group. The remaining 49% is owned by Spark Infrastructure.
