How to read this
Every figure is OpenStream's estimate, not a retailer quote: the supply and usage rates each retailer publishes to the Australian Energy Regulator (via Energy Made Easy), applied to the stated annual usage, GST as published, conditional discounts excluded. Prices vary by distribution network, not postcode, so the network page is the record; it links every plan to its regulator entry and keeps a nightly history. Demand-priced, variable-priced and solar-only plans are left out because they have no single honest figure. Errors are possible - check the cited sources. Full method: methodology.
