Compare Electricity Plans in SA — 2026

South Australia has historically had some of Australia's highest electricity prices, making plan comparison essential. The 2026 Default Market Offer (DMO) from the AER caps standing offer prices, but competitive market offers can deliver significant savings. With SA's strong solar resources, households with rooftop PV should also compare feed-in tariff rates.

What is the DMO?

The Default Market Offer (DMO) is set annually by the Australian Energy Regulator (AER). It represents the maximum price a retailer can charge on their standing offer. When we show a plan as "X% below the DMO", that means its estimated annual cost is X% cheaper than this reference price — helping you quickly identify genuine savings.
