WA households cannot choose their electricity retailer. Synergy supplies the South West Interconnected System and Horizon Power the regions, both on government-set tariffs. Solar, and shifting usage into daylight hours, are the levers available here.
How we worked this out
Western Australia runs its own market outside the NEM, with prices set by the state government rather than the AER.
Typical bills use average single-rate residential rates for 2026–27 (effective 1 July 2026), from the AER Default Market Offer and ESC Victorian Default Offer determinations, reviewed 20 July 2026. Cheapest plan figures are indicative, based on the lowest-cost plans on our panel excluding conditional discounts. Your bill depends on your retailer, tariff type, meter and usage pattern. This is a guide, not a quote.
