Electricity distribution

Electricity is supplied to most Queensland customers via an electricity distribution system, which connects the high-voltage transmission system to individual customer premises.

These distribution systems (also called supply networks) consist of electric lines, substations and associated equipment.

Queensland's electricity distribution networks are extensive, with a total line length of about 232,000km. Three distributors supply 2.3 million industrial, commercial and domestic electricity consumers.
