Compare the estimated annual cost, not just the advertised cents-per-kilowatt-hour rate, because supply charges and your usage patterns also affect the bill. Check whether rates vary by time of day, whether discounts are conditional, and whether the plan includes controlled-load or solar feed-in rates if relevant to your home. Retailer comparison tools and your state or territory’s official energy comparison service can help assess available offers. Prices and eligibility depend on your location, meter and circumstances, so confirm the plan details directly with the retailer before switching.
