Our Network

Our network extends throughout NSW and the ACT, with connections to Queensland and Victoria. It forms the backbone of the National Energy Market (NEM) and enables trading between Australia's three largest states along the east coast.

High voltage bulk electricity is carried from generators through 13,000 kilometres of high voltage transmission lines, underground cables and substations. This is converted at our substations to low voltage electricity suitable for household consumption. Distribution networks then deliver electricity through smaller poles and wires to more than three million homes and businesses.
