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.
