ElectraNet

South Australia's electricity system is the most renewables-intensive in Australia, with wind and solar generation regularly meeting the entirety of state demand, and the state government has adopted targets of 100% net renewable electricity generation by 2027 and net zero emissions by 2050. In its 2026 Transmission Annual Planning Report, ElectraNet projected that the state's peak electricity demand could more than double over the following 15 years, rising from about 3.3 GW to more than 6.5 GW, driven by data-centre construction, defence-industry expansion, mining and minerals development, steel production at Whyalla and the Northern Water desalination project. The report set out a pipeline of priority transmission projects valued at around A$3.94 billion.
