    South Australia's electricity costs

    South Australia has a single electricity distribution network — SA Power Networks — covering the entire state. SA has some of the highest average electricity bills in Australia, with benchmark costs around $2,100 per year for a typical household. The high costs are driven by a combination of network infrastructure investment, the state's transition to renewable generation, and historically higher wholesale prices.

    Despite the high average costs, South Australia has a competitive retail market with 14 retailers publishing offers. This competition means switching from a standing offer to a competitive market offer can save households up to $350 per year — one of the highest potential savings of any Australian state. The AER Default Market Offer (DMO) applies in SA and acts as a reference price benchmark.
