That said, things to consider when comparing plans include: How a plan’s annual estimated cost compares to the reference price. The usage charge per kilowatt hour (kWh) and daily supply charge. Whether those charges are variable or fixed for a specific term. If the plan includes a guaranteed or conditional bill discount. Your tariff type - do you need a single rate, a time of use tariff, or do you require a controlled load? If there’s benefits for solar owners, such as a feed-in tariff.
