Regulated minimum. A regulator sets a mandatory floor that retailers must at least match — the most stable arrangement. Tasmania (OTTER) and regional Queensland (QCA, in the Ergon network) work this way.
Benchmark. A regulator publishes a guide range for transparency, but it isn’t binding. New South Wales (IPART) is the clearest example — retailers can, and do, price above or below the benchmark.
Deregulated. No mandated minimum beyond a zero floor; rates are set by the market. Victoria moved to this model on 1 July 2025, joining South Australia, the ACT and south-east Queensland. This is the big trap for stale comparison pages — Victoria no longer has a minimum to quote.
Government buyback scheme. Outside the National Electricity Market, Western Australia (DEBS) and the Northern Territory (Jacana) pay set, often time-based rates that reward exporting in the evening peak rather than the saturated middle of the day.
Whatever the model, the feed-in tariff is only one part of the picture. A plan with a slightly lower feed-in rate but meaningfully cheaper usage charges can save you more overall — which is why we point you to compare the whole plan.
