Electricity supply

Ausgrid distributes electricity to customers in the Sydney, Central Coast and Hunter regions of NSW, along a vast network of substations, poles and wires.

The Ausgrid network distributes more than 30,000 GWh of electricity annually, to just under 1.7 million customers through over 49,000km of both overhead lines and underground cables.  

Our electricity supply is taken from the NSW transmission network at either 132,000 or 66,000 volts and reduced to 33,000, 22,000 or 11,000 volts through a network of transmission and zone substations. Street-based distribution substations further reduce supply to levels that meet our customers’ home or business requirements.
