Quick Facts




Network lines


Peak demand

SA Power Networks has a history of ranking as the most efficient electricity distributor on a state-by-state basis in the National Electricity Market, and has the second lowest state-by-state distribution charges per residential customer.

Services include maintaining and building a reliable distribution network, responding to outages including those caused by extreme weather, and ensuring community safety from electric shock and bushfires. The average customer pays about $10 per week for these services. In real terms, customers pay the same amount as they did in 1999, due to efficiency of the business. This means SA Power Networks’ share of the residential bill has fallen from 50% in 1999 to about 30% in 2019.

SA Power Networks has the second lowest state by state distribution charges per residential customer.
