Electricity Comparison in South Australia

The Australian Energy Regulator sets the Default Market Offer, the regulated price benchmark for customers in SA, NSW, and South East Queensland. It reviews this benchmark every 1 July. The Essential Services Commission of South Australia monitors retail conduct and retailer compliance with billing and customer protection rules.

Retailers set their own market offer prices within this framework. That competition is what produces savings for SA customers. GoSwitch reflects this regulatory framework and is a credible, compliance-aware comparison resource for South Australian energy customers.

SA households can choose between four tariff types, and the right choice affects what you pay on your bill. GoSwitch generates tailored recommendations based on your usage patterns, appliances, and time-of-use behaviour, not a generic list. Each tariff type suits a different usage profile.

• A single rate tariff (flat rate or basic plan) charges one usage rate at all hours, suiting homes with steady consumption.
• A time-of-use tariff charges different rates across peak, shoulder, and off-peak periods, best suited to smart meter households that shift appliances.
• A controlled load tariff applies a lower off-peak rate to dedicated circuits like electric hot water systems, without changing the main tariff.
• A demand tariff adds a demand charge based on your highest electricity use during a set peak window.

SA has had no minimum feed-in tariff since ESCOSA removed the regulated rate in January 2017. Retailers now set their own rates, with 2026 figures ranging from 3 to 10 cents per kWh. That low range reflects SA’s high solar panel penetration, which pushes down the value of daytime exports.

That makes self-consumption the smarter play. Avoiding a 32c/kWh grid import saves three to six times more than earning 5c/kWh on exports. Comparing usage rates alongside solar feed-in tariffs gives a clearer picture, and GoSwitch does both together for SA solar households.

SA government rebates can reduce your electricity costs, and each one counts when comparing plans. GoSwitch includes rebate and concession details so all South Australians can compare with the full picture. These are the current SA rebates.

• The Energy Concession provides up to $281.78 per year (2025-26 rate, indexed annually) as a daily bill credit. Eligible card types include the Pensioner Concession Card, Health Care Card, Low Income Card, and Veterans’ Affairs Gold Card.
• The Medical Heating and Cooling Concession offers up to $281.78 per year for households where a doctor-certified condition requires extra heating or cooling.
• The Cost of Living Concession pays $261.90 in 2025-26 via EFT to eligible low and fixed-income households.
• The Australian Government Energy Bill Relief Fund ended 31 December 2025, and the two $75 credits totalling $150 are no longer available. Visit the Concessions SA page at sa.gov.au to check your eligibility.
