Our Story & Purpose

We are leaders in the energy transition, delivering reliable and sustainable electricity transmission services and valued customer connections.

Device Our Story & Purpose

A Powerful History

South Australia’s electricity journey started back in 1885, when J.W.H Hullet became the first person to light a private residence through what was known as a hydro-electric plant. But it wasn’t until 1897 that the South Australian Parliament passed a bill to form a privately owned electricity company to generate and transmit power to the Port Adelaide area.

Our Vision

Energising South Australia’s Clean Energy Future.

Our Purpose

We are leaders in the clean energy transition, delivering reliable and sustainable electricity transmission services and valued customer connections

Early 1900's

The demand for electricity soared throughout the early 1900s. By 1917, electricity supplies had been extended to Norwood, Unley, Hindmarsh and Thebarton, and the demand was so high that the powerhouse that had initially been built in Grenfell Street needed to expand its capacity. By 1923, a further power station was built in Osborne to cope with customer demand.

The 1920s saw new transmission lines being built, expanding out past the metropolitan area. By the Second World War, transmission lines were delivering power to the farmlands of South Australia, providing electricity to industrial sites and important war-effort supply stores.

Eventually, the South Australian Government reasoned that an adequate, reliable and centrally planned electricity supply was key to the growth of the state’s industry and agriculture. The Government formed the Electricity Trust of South Australia (ETSA) and nationalised privately owned electricity companies.

1950's - 1997

During the 1950s, the Port Augusta power stations came online and the Power Line Carrier communications system was first used to relay a conversation between Northfield and Port Augusta. It enabled the remote operation and monitoring of the transmission network. ElectraNet has the largest private telecommunications network in the state.

The Northern Power Station was commissioned in 1985 to supply additional base load power. The connection between Adelaide and Port Augusta was also reinforced to meet the growing demands of metropolitan Adelaide. Around the same time, an agreement was made to connect the transmission networks of Victoria and South Australia, and an interconnector was built in Heywood, Victoria.

1998 - Current

ElectraNet entered the story in 1998, when the South Australian Premier, John Olsen, announced the privatisation of ETSA. We began trading as a private company in 2000.

In 2005, Cathedral Rocks became the first wind farm connected to ElectraNet’s transmission network. We have now become the largest connector of wind generation in Australia, and the second largest wind-to-load ratio in the world.

With demand for electricity continuing to grow in South Australia, we bolstered the high-voltage supply to Adelaide CBD with a new underground cable in 2011. Our commitment to providing stable, reliable, and high quality electricity continues, with the interconnector in Heywood next in line to be upgraded in the near future, to increase the capacity in both directions by 40%.
