Network Map
ElectraNet’s ‘super highways’ of high-voltage power are the backbone of our electricity transmission network.
Across the diverse and rugged state
The electricity transmission network in South Australia extends across some 200,000 square kilometres of diverse and rugged terrain, operating at voltages of 330, 275, 132 and 66 kilovolts (330,000, 275,000, 132,000 and 66,000 volts). The network includes more than 90 high-voltage substations with approximately 6,600 circuit kilometres of transmission lines.
