Our Heritage Developing The No. 1 The story of electricity supply and transmission in South Australia South Australia Converter From its very inception, the electricity supply network in South Australia has been helping our State develop and grow. In its early days, the advent of Station electricity supply rapidly improved the quality of life of South Australians and as the State matured, the transmission network’s increasing reach opened up new industries and opportunity. Today, our modern transmission network continues to support the people of South Australia by providing safe, affordable and reliable solutions to power homes, businesses and the economy.
