Start by entering your Adelaide postcode and recent usage into the Australian Government’s Energy Made Easy comparison tool, which lists available electricity offers and estimated costs. Check the supply charge, usage rates, discounts, contract terms, exit fees and whether the plan suits solar, controlled-load or time-of-use customers. Adelaide electricity is generally distributed by SA Power Networks, so changing retailers usually does not change the poles and wires serving your property. Your final costs and eligibility for concessions depend on your household and the retailer’s terms, so confirm the offer directly before switching.
