No. A retailer files different prices for each electricity network, and which plan costs least depends on how much power a home uses and when. A plan with a low daily supply charge can cost less for a small home and more for a large one. So each plan here is priced as a year’s bill for your household at your postcode, and the answer is for your home, not an average.

New South Wales, the ACT, Victoria, Queensland, South Australia and Tasmania: the states the Australian Energy Regulator’s plan data covers. Western Australia and the Northern Territory aren’t in it, so their plans aren’t here. Prices depend on your electricity network, so only the plans filed for your postcode are shown.

Use your bill: the kWh it shows, or just what it cost, for a month, a quarter or a year. Without a bill, pick your household size and we use the Australian Energy Regulator’s benchmark for homes like yours in your state. Your smart-meter file is the most exact: ask your retailer or electricity distributor for your interval data in NEM12 format.

Because it decides which plan costs least. Many plans charge more in the evening peak and less overnight or in the middle of the day, so the same plan can be among the cheapest for a home that’s empty on weekdays and among the dearer for one that’s busy all day. If you’re not sure, each plan is priced three ways and those that stay cheap whatever your pattern are marked.

By what your exports would earn in a year, not by the advertised rate. A high rate paid only in some hours, or only on the first few kWh a day, can earn less than a lower flat rate. Your panels’ output is worked out hour by hour from their size and your state’s average sunshine, your home uses what it needs as it’s made, and the rest is priced on each plan’s feed-in schedule as part of the year’s bill.

Yes. Retailers file their usage and supply charges without GST, so we add it. Guaranteed discounts are taken off; a discount you get only for paying on time or by direct debit is shown on the plan but not counted, since it depends on you. A sign-up credit counts in the first year only.

From the Australian Energy Regulator. Every retailer must file its generally available plans with the AER, which publishes them through the Consumer Data Right, the same data behind the government’s Energy Made Easy site. We read that feed every night.

It stays in your browser. The page reads it on your device, works out your usage by hour, month and weekday, and keeps only that summary on this device so the results remember it. The file itself is never uploaded to us.

Some plans can only be taken through a comparison site or a partner, or only by members of a club, seniors card holders or existing customers, so they’re left out. Plans made for homes with solar, a battery or an electric car are shown only if you say you have one. Wholesale-price plans, like Amber and Flow Power, publish only an estimate of prices that change through the day, so they’re marked as estimates and never ranked against fixed prices.
