SA Power Networks (until 3 September 2012, ETSA Utilities[2]) is the sole electricity distributor in South Australia, delivering electricity from high voltage transmission network connection points, operated by ElectraNet, through a network of about 87,500 kilometres of powerlines, to about 830,000 residential and business customers throughout most of South Australia.

SA Power Networks is the fifth largest electricity distributor in the Australian National Electricity Market.


SA Power Networks arose from the split up of the Electricity Trust of South Australia and its subsequent privatisation. It is owned by the Hong Kong-based Cheung Kong Infrastructure Holdings[1] (51%), and Spark Infrastructure (49%). SA Power Networks is structured as a partnership of CKI Utilities Development Limited,[3] PAI Utilities Development Limited, each incorporated in the Bahamas; and Spark Infrastructure SA (No. 1) Pty Ltd, Spark Infrastructure SA (No. 2) Pty Ltd, and Spark Infrastructure SA (No. 3) Pty Ltd, each incorporated in Australia.

Regulated electricity distribution[edit]

SA Power Networks operates its electricity distribution business under a licence granted by the Government of South Australia.

The business is subject to regulation by the Australian Energy Regulator and Essential Services Commission of South Australia. Regulation of the business primarily relates to the tariffs required to meet regulated service standards cost efficiently.

In September 2016, the State experienced the 2016 South Australian blackout.

Other business activities[edit]

SA Power Networks also competes in the un-regulated energy market providing infrastructure construction and maintenance services to industry and government.

The company is a client of registered lobbyist and former Labor party senator, Nick Bolkus.[4]
